    Full Text Available Background: Acute Kidney Injury results from pre renal, post renal or intrinsic renal causes. Reflex anuria is a very rare cause of renal impairment which happens due to irritation or trauma to one kidney or ureter, or severely painful stimuli to other nearby organs. Case Presentation: Here we present a case of acute kidney injury secondary to reflex anuria in a patient who underwent extensive gynecological surgery along with ureteral manipulation which recovered spontaneously. Conclusion: Reflex Anuria is a rare and often not considered as cause of acute kidney injury. This case illustrates that this should be kept as a differential in potential cause of acute kidney injury in patient undergoing urogenital or gynecological surgeries.

    Full Text Available Aim. Оptimize the treatment of patients with prolonged anuria kidney transplantation due to the introduction of the diagnostic algorithm and treatment of patients at risk. Materials and Methods. 145 renal transplant recipients who had surgery during the period from 2006 to 2011. Of these – 73 (50.3% patients with anu- ria period exceeding 3 years. An algorithm for the treatment of patients with prolonged anuria kidney trans- plantation, which consists of three stages: pre-operative, peri-operative and post-operative. In the study, two groups. The first group of 47 patients, which were held all three stages of the algorithm evaluation and treat- ment of patients with prolonged anuria in kidney transplantation. The second group of 26 patients with pro- longed anuria without urological examination and treatment. Results. Implementation of the proposed algo- rithm of diagnosis and treatment of patients with prolonged anuria can reduce the risk of adverse outcome of 11. Additional specific urological examination and treatment can reduce the number of urological com- plications, both in the immediate and late postoperative period by 20%. The emergence of severe urological complications in patients with prolonged anuria increases the risk of adverse outcome of 17. The most pre- ferred anastomosis urinary tract in recipients were on long-term renal replacement therapy is an immersion- type anastomosis «drop in». Renal transplant patients with prolonged anuria preferable to perform up to 45 ye- ars, as this reduces the relative risk of an adverse outcome by 14 times compared with the older age group.Conclusion. Prolonged anuria in a patient with chronic renal failure awaiting a kidney transplant, is not a con- traindication to the operation. The duration of anuria not significantly affect the results of renal transplantation.

However, clinical studies are limited, and few have explored the potential confounding effect of anuria. This study, thus, evaluated the association between IS and anemia in both non-anuric and anuric peritoneal dialysis (PD patients.Methods: This cross-sectional and observational study included 165 chronic PD patients aged 19–84 years. Their serum IS levels in total and free forms were measured by ultra performance liquid chromatography. Correlations between serum IS and hemoglobin (Hb were performed in both non-anuric and anuric groups.Results: Among the study subjects, 90 were non-anuric and 75 were anuric. As a whole, there was no correlation between IS and Hb. Nonetheless, subsequent analysis of the non-anuric patients showed that Hb is negatively correlated with IS levels (rs=-0.405, P<0.001 for total form and rs=-0.296, P=0.005 for free form. Factors that significantly affected Hb levels in the stepwise multiple regression analysis include total IS and iron saturation. In contrast for anuric patients, serum ferritin, albumin, iron saturation, use of angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker, but not serum IS, were predictors for anemia in the multiple regression model.Conclusions: Serum IS is associated with an increased severity of anemia in non-anuric PD patients and not in anuric ones, indicating anuria could be a confounding factor in such association.

    To present our experience with emergency ureteroscopic lithotripsy (URSL) for ureteral calculi associated with acute kidney injury (AKI). We retrospectively evaluated the 61 patients consisted of 90 ureteral units (UU), who underwent URSL. The cause of anuria was bilateral calculus obstructions in 29 cases, and unilateral calculus obstruction with, absent, nephrectomized contralateral kidney in 32 cases. In the case of bilateral synchronous ureteric calculi same-session bilateral ureteroscopy (SBBU) was done. The duration of anuria varied between 12 to 72 hours. At the end of the procedure, ureteral stent was systematically left in place in all patients. Surgery was performed 6-12 hours after admission to hospital. Patients were followed at least 1 month postoperatively. The stone free rates (SFR) were determined as baseline, on the first post-operative day, and as overall on the 30 days after procedure. The greatest success was achieved in the distal localization of stones up to 10 mm (93%). Renal function returned in 51 (83.6%) patients within 7 days. In 18 (29.5%) patients [18 (20%) UU] we performed second procedure as extracorporeal shockwave lithotripsy in 16.7% and open surgery in 2.2%. In 43 (70.5%) patients URSL was a successful therapeutic approach in dealing with pain, obstruction and calculus. Calculus anuria is a medical emergency that requires rapid diagnosis and prompt treatment for the purpose of decompression. URSL is the proper method of choice for selected patients and can be performed safely and has high success rates with minimal morbidity.

    Full Text Available A young female presenting with right flank pain, fever, raised creatinine and bilateral hydronephrosis was treated with antibiotics elsewhere, with presumptive diagnosis of bilateral pyelonephritis. She had partial relief in symptoms and her creatinine level showed an improvement. Three months later during evaluation at our center she had anuria, hypertensive crisis and pulmonary edema which were managed with emergency bilateral percutaneous nephrostomies. Cross-sectional imaging and ureteroscopy suggested bilateral synchronous intramural mid-ureteric lesions as underlying pathology. Histopathology of the ureteric segments during laparotomy revealed caseating granulomas suggestive of tuberculosis. This clinical presentation has not been previously described in urinary tuberculosis.

    Ursine hibernation uniquely combines prolonged skeletal unloading, anuria, pregnancy, lactation, protein recycling, and lipolysis. This study presents a radiographic and biochemical picture of bone metabolism in free-ranging, female American black bears (Ursus americanus) that were active (spring bears and autumn bears) or hibernating (hibernating bears). Hibernating bears included lactating and non-lactating individuals. We measured serum calcium, albumin, inorganic phosphate, creatinine, bone specific alkaline phosphatase (BSALP), CTX, parathyroid hormone, insulin-like growth factor-I (IGF-l), leptin, 25-hydroxyvitamin D [25(OH)D], 1,25-dihydroxyvitamin D [1,25(OH)(2)D] and sclerostin from 35 to 50 tranquilized hibernating bears and 14 to 35 tranquilized spring bears. We compared metacarpal cortical indices (MCI), measured by digital X-ray radiogrammetry, from 60 hunter-killed autumn bears and 79 tranquilized, hibernating bears. MCI was greater in autumn than winter in younger bears, but showed no seasonal difference in older bears. During hibernation eucalcemia was maintained, BSALP was suppressed, and CTX was in the range expected for anuria. During hibernation 1,25(OH)(2)D was produced despite anuria. 1,25(OH)(2)D and IGF-I were less in hibernating than spring bears. In a quarter of hibernating bears, sclerostin was elevated. Leptin was greater in hibernating than spring bears. In hibernating bears, leptin correlated positively with BSALP in non-lactating bears and with CTX in lactating bears. Taken together the biochemical and radiographic findings indicate that during hibernation, bone turnover was persistent, balanced, and suppressed; bone resorption was lower than expected for an unloaded skeleton; and there was no unloading-induced bone loss. The skeleton appears to perceive that it was loaded when it was actually unloaded during hibernation. However, at the level of sclerostin, the skeleton recognized that it was unloaded. During hibernation leptin

    Ceftriaxone is known to cause biliary pseudolithiasis and, rarely, nephrolithiasis mainly in children. However, we reported the development of bilateral distal ureteral ceftriaxone-associated lithiasis in 7 adults, which suggests that the risk of ureterolithiasis impaction should be considered when treating patients with ceftriaxone, even in adults. To avoid strengthening greater renal damage, ureteroscopic insertion of double J stents may be an alternative management for patients with ureteral ceftriaxone-associated lithiasis.

    ♦ Background: Residual renal function (RRF) is an important prognostic indicator in continuous ambulatory peritoneal dialysis (CAPD) patients. We determined the predictors of RRF loss in a cohort of incident CAPD patients. ♦ Methods: We reviewed the record of 645 incident CAPD patients. RRF loss is represented by the slope of decline of residual glomerular filtration rate (GFR) as well as the time to anuria. ♦ Results: The average rate of residual GFR decline was -0.083 ± 0.094 mL/min/month. The rate of residual GFR decline was faster with a higher proteinuria (r = -0.506, p peritonitis episodes were independent predictors of progression to anuria, while a higher baseline GFR was protective. Each 1 g/day of proteinuria is associated with a 13.2% increase in the risk of progressing to anuria, each 10 g/day higher glucose exposure is associated with a 2.5% increase in risk, while each peritonitis episode confers a 3.8% increase in risk. ♦ Conclusions: Our study shows that factors predicting the loss of residual solute clearance and urine output are different. Proteinuria, baseline residual GFR, and the use of diuretics are independently related to the rate of RRF decline in CAPD patients, while proteinuria, glucose exposure, and the number of peritonitis episodes are independent predictors for the development of anuria. The role of anti-proteinuric therapy and measures to prevent peritonitis episodes in the preservation of RRF should be tested in future studies. PMID:24497594

    Hemolytic uremic syndrome (HUS) is a main cause of acute renal failure in children. This study aimed to analyze the clinical characteristics of HUS. A retrospective analysis was performed in 46 children with sporadic HUS. Of the 46 HUS patients, 20 (43.5%) were diarrhea-related HUS, and 26 (56.5%) were atypical HUS. Anemia, edema, oliguria, hemoglobinuria and hypertension were the most common manifestations. Thrombocytopenia, hyponatremia, hypocalcemia, hyperkalemia, metabolic acidosis, increased fibrinogen and hypocomplementemia were found in most patients. The age of onset (younger than 2 years or not, P=0.009), the duration of oliguria or anuria (more than one week or not, P=0.005), accompanied with extrarenal complications or not (P=0.005), dialysis and plasma exchange (P=0.04) were associated with the mortality rate. The age of onset younger than 2 years, oliguria/anuria more than 1 week, and associated with extrarenal complications were predictive factors of poor prognosis.

  12. Electro-thermal injuries due to high-current accidents with special regard to the skeletal muscles

    Rausch, M.

    1982-02-25

    Seven patients suffering from high-current accidents with different degrees of severity are reported on. Damages to the striped musculature are preferentially considered. When the function of the cellular membrane is affected by an electric current, the Na/sup +//K/sup +/ mechanism collapses due to an increase of membrane permeability for calcium. Depolarisation, development of contractures, changes of the fibrillar structures and decay of the stripes or swelling of the Q (A) substance were found to indicate damage. A particular effect of electrothermal muscle damages is the affection of other organs, e.g. of the kidneys, provoked by an increased chromoprotein production and a higher output of myoglobin and hemoglobin. Since in case of an accident due to electric current affecting the musculature, more acid substances enter the vascular system, an acute renal damage provoked by an alkalinisation of the urine, shall be treated by drugs. In most cases, an anuria, occurring several days after deep burn of musculature, is a so-called constipational anuria, if it is not an anuria induced by a decrease of blood pressure or by shock. The therapy of wounds due to electrical burning depends on the size of the affected skin area and down to which depth the tissue is burnt. Particular attention must be paid to the affection of bones being situated in the depth of wounds due to burning. In the last part of the study possible reconstructive and ensuing rehabilitation measures are indicated.

    Full Text Available Acute aortic dissection (AAD is a life-threatening condition associated with high morbidity and mortality. The most important recognized acquired cause that leads to dissection is chronic arterial hypertension. With respect to the anuria and renal failure, aortic dissection is not something that is always considered and is still not a very common presentation unless both renal arteries come off the false lumen of the dissection. However, when present, preoperative renal failure in patients with acute type B dissection has been noted to be an independent predictor of mortality. Early recognition and diagnosis is the key and as noted by previous studies as well, almost a third of these patients are initially worked up for other causes until later when they are diagnosed with aortic dissection. Here we present a case of a patient presenting with severe hypothyroidism, long-standing hypertension, and anuria. Through the case, we highlight the importance of having aortic dissection as an important differential in patients presenting with anuria who have a long standing history of uncontrolled hypertension. Pathophysiology relating to severe hypothyroidism-induced renal dysfunction is also discussed.

    The thrombotic occlusion of one renal artery may become completely asymptomatic, due to the functionality of the contralateral kidney. However, in rare circumstances, such is the case of individuals with a solitary kidney, a situation of anuria and acute renal failure may constitute the main presentation of the condition. The authors report the clinical case of a 43 year old male patient, with the previous diagnosis of an infrarenal aortic occlusion and a single left kidney, who developed a thrombotic occlusion of the renal artery, with anuria and acute renal failure. The patient underwent an emergency revascularization procedure, consisting in the implantation of a prosthetic bypass graft from the superceliac aorta to the renal artery, with immediate recovery of the diuresis and renal function. Seventeen months later as a consequence of an anastomotic hyperplasia, an occlusion of the bypass graft occurred, again with anuria and acute renal failure. The patient was reoperated on and due to the inadequacy of both saphenous veins to be used as the material of choice for the revascularization procedure, a redundant segment of the left colic artery (Riolan's arcade) was removed and used as an interposition graft, from the middle colic artery to the renal artery, followed by an immediate restoration of diuresis and renal function. The singular and recurrent character of this clinical condition and the utilization of an original, eventually unique and well succeeded revascularization procedure, prompted its presentation and divulgation.

E-mail: tatiana@fmvz.unesp.br Acute renal injury is characterized by a sudden injury in renal parenchyma that causes loss in its excretory, metabolic and endocrine function. The dialysis therapy has been instituted in the small animal clinic aimed at removing metabolic waste and correcting electrolyte disturbances of renal dysfunction. Peritoneal dialysis is a therapy based on the use of the peritoneum as a semipermeable membrane through which there is exchange of solutes and fluid between blood from the peritoneal capillaries and the dialysis solution. We describe a case of acute kidney injury refractory to drug therapy in a canine female mixed-breed, with 13 years old. The patient was presenting anorexia, vomiting, decubitus and anuria, had a history of prolonged treatment with anti-inflammatory drugs, was azotemic and in metabolic acidosis. Anuria persisted after drug therapy (volume restoration, chemical and osmotic diuresis and renal vasodilation then starting to peritoneal dialysis (PD. Were performed three cycles of PD, during the second cycle patient left anuria and at the end of the third cycle showed clinical improvement, reduction of azotemia, hyperkalemia and metabolic acidosis. PD has shown satisfactory results, reversing the anuria, reducing azotemia and electrolyte disturbances, thereby providing clinical improvement.

    Full Text Available Acute kidney injury (AKI is a common complication of liver cirrhosis and mainly manifests as a rapidly elevated serum creatinine level, a reduced glomerular filtration rate, and oliguria or anuria. Type 1 hepatorenal syndrome (HRS-1 is a special type of AKI, and patients with untreated HRS-1 have an extremely high risk of death. Early diagnosis and treatment are of great importance. This paper summarizes the latest diagnostic criteria for hepatorenal syndrome (HRS type of AKI and research advances in the treatment of HRS-1.

    Purpose: The metastatic differentiated thyroid cancer represents an indication of isotopic treatment by an ablative dose of iodine 131, but the coexistence of an anuric renal failure poses very serious problems and requires adequate logistics. Conclusions: Surgical treatment is the rule, isotope treatment is less in a number of cases. The initial staging of the disease of our patient has imposed an additional treatment based on {sup 131}I, but complicated by anuria which is the elimination path. Interdisciplinary cooperation allowed to stabilize the case of this patient. (N.C.)

    Hemodialysis was performed in 2 cases of acute renal insufficiency after radiotherapy of carcinoma colli (Stage III of carcinoma colli). This experience was reported including discussion. One patient developed ileus and uremia approximately 6 months after radiotherapy (telecobalt 6000 R and radium 1800 mgh). The other complained of anuria and low fever approximately 3 years after radiotherapy (telecobalt 6000 R and radium 3800 mgh), which led to the presumption of post-renal urinary retention due to complete obstruction of the ureter. Both patients escaped from crisis by hemodialysis. (Kanao, N.)

    Full Text Available We report a 50-year-old male patient with diabetes mellitus and hypertension who presented with low-grade fever, anuria and renal failure. He had no prior history of nephropathy and retinopathy. Since anuria persisted, a renal biopsy was performed using automated gun, under ultrasound guidance. Two hours after the renal biopsy was performed, the patient developed severe left loin pain that required analgesics and sedatives. Ultrasound of the abdomen performed immediately, two hours and four hours after the biopsy, did not reveal any hematoma. The hemoglobin was stable when the patient developed loin pain, but after eight hours decreased to 9.1 g/dL, and computed tomography scan of the abdomen revealed a big peri-nephric hematoma around the left kidney. He was managed with blood transfusions and a selective angiogram was done. It revealed a pseudoaneurysm and arterio-venous fistula from the segmental artery of lower pole of the left kidney; both were closed by using microcoils and liquid embolic agent N-butyl-cyanoacrylate (NBCA. The only risk factor the patient had at the time of renal biopsy was severe renal failure. Our case suggests that severe loin pain immediately after renal biopsy in a patient with renal failure warrants careful follow-up of hemoglobin and imaging, even if initial imaging is normal. Further fall of hemoglobin necessitates early evaluation with angiogram, which helps in diagnosing the treatable, although rare, complications like pseudoaneurysm and arterio-venous fistula.

    Malaria has protean clinical manifestations and renal complications, particularly acute renal failure that could be life threatening. To evaluate the incidence, clinical profile, ou come and predictors of mortality in patients with malarial acute renal failure, we retrospectively studied the last two years records of malaria induced acute renal failure in patients with peripheral smear positive for malarial parasites. One hundred (10.4%) (63 males, 37 females) malaria induced acute renal failure amongst 958 cases of acute renal failure were evaluated. Plasmodium (P). falciparum was reported in 85%, P. vivax in 2%, and both in 13% patients. The mean serum creatinine was 9.2 ± 4.2 mg%, and oligo/anuria was present in 82%; 78% of the patients required hemodialysis. Sixty four percent of the patients recovered completely, 10% incompletely, and 5% developed chronic kidney failure; mortality occurred in 21% of the patients. Low hemoglobin, oligo/anuria on admission, hyperbilirubinemia, cerebral malaria, disseminated intravascular coagulation, and high serum creatinine were the main predictors of mortality. We conclude that malaria is associated with acute renal failure, which occurs most commonly in plasmodium falciparum infected patients. Early diagnosis and prompt dialysis with supportive management can reduce morality and enhance recovery of renal function (Author).

  1. Causes and Treatment of Acute Renal Failure in Children

    Full Text Available Objective: to study the causes of acute renal failure (ARF in children and to substantiate recommendations on its treatment. Fifty-nine children with ARF were followed up in 1979 to 2004. In 90% of the patients, ARF was established to be caused by hemolytic uremic syndrome (HUS, acute intestinal infection (AII, acute glomerulonephritis, and acute intravascular hemolysis. The major cause of ARF was AII in two thirds (66.1% of the children. In the past decade, the incidence of HUS has decreased from 55 to 40%. The authors identified the following predictors of poor ARF outcome: early age, anuria, impaired consciousness progressing to spoor and coma. A combination of these symptoms is most frequently observed in patients with HUS in which the kidneys are the major target organ and the possibilities of more than 7-day treatment for anuria without dialysis are limited. In other etiology of ARF, water deprivation, antihypertensive therapy, and exchange plasmapheresis allow patients to survive until renal function restores without renal replacement therapy, by preventing serious complications.

    Current methods for rapid detection of delayed graft function (DGF) after kidney transplantation are unreliable. Urinary clusterin is a biomarker of kidney injury but its utility for prediction of graft dysfunction is unknown. In a single-center, prospective cohort study of renal transplant recipients (N=81), urinary clusterin was measured serially between 4 hr and 7 days after transplantation. The utility of clusterin for prediction of DGF (hemodialysis within 7 days of transplantation) was compared with urinary interleukin (IL)-18, neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1, serum creatinine, and clinical variables. At 4 hr after reperfusion, anuria was highly specific, but of low sensitivity for detection of DGF. At 4 hr, receiver operating characteristic analysis suggested that urinary clusterin, IL-18, kidney injury molecule-1, and NGAL concentration were predictive of DGF. After adjusting for preoperative clinical variables and anuria, clusterin and IL-18 independently enhanced the clinical model for prediction of DGF. Kidney injury molecule-1 only modestly improved the prediction of DGF, whereas NGAL, serum creatinine, and the creatinine reduction ratio did not improve on the clinical model. At 12 hr, the creatinine reduction ratio independently predicted DGF. Both urinary clusterin and IL-18 are useful biomarkers and may allow triaging of patients with DGF within 4 hr of transplantation. Relative performance of biomarkers for prediction of graft function is time-dependant. Early and frequent measurements of serum creatinine and calculation of the creatinine reduction ratio also predict DGF within 12 hr of reperfusion.

    Noncontrast computed tomography (CT) has great advantage with higher sensitivity and more clear modalities in detecting urinary tract radiolucent calculi in patients with acute renal insufficiency (ARI) compared to other image diagnosis approaches. We report two cases (female, 28 years old; male, 39 years old) with persistent flank pain and acute anuria after the administration of ceftriaxone (4.0 g daily) for 2 days intravenously. No abnormality was found in the kidney-ureter- bladder (KUB) areas with plain abdomen X-rays. A diagnosis of bilateral hydronephrosis was made by ultrasound examination in both cases. Serum creatinine levels reached up to 257 and 810 μ mol/L (normal serum creatinine level is 40-130 μ mol/L), respectively. Vague density spots were noticed in the pelvis with noncontrast multidetector-row CT (MDCT) scanning. However, distinguishable clusters of high-density shadows were seen in pelvic areas with maximum intensity projections (MIP, CT values in 30-128 HU). Ceftriaxone crystal calculi were found on both sides of distal ureters under endoscopy. Renal function recovered in both patients after double-J ureteral stents were installed. Out results demonstrated that noncontrast MDCT scanning and MIP reconstruction as an effective diagnostic tool could provide clear images in detection of radiolucent calculi in urinary tract when conventional X-rays image are not suitable in the patients with obstructive anuria and ARI of unknown origin.

    A 70-year-old male patient was admitted complaining of weakness and pain in his arms and lower limbs. His serum creatine kinase and serum creatinine were markedly elevated (36,248 IU/L and 2.8 mg/dL, respectively). He had taken dexketoprofen trometamol because of a common cold, which had developed the previous night. Acute kidney injury caused by dexketoprofen-induced rhabdomyolysis was diagnosed by ruling out other possible causes, such as dermato/polymyositis, myxedema, brucellosis, and hepatitis. Dexketoprofen administration was stopped. As diuresis did not restore spontaneously, the patient was treated with I.V. alkaline solutions and mannitol. Hemodialysis was performed because of anuria and severe metabolic acidosis. The patient's renal function later recovered. In conclusion, dexketoprofen may be a potential risk factor for acute kidney injury and rhabdomyolysis.

    Acute kidney injury (AKI) secondary to near-drowning is rarely described and poorly understood. Only few cases of severe isolated AKI resulting from near-drowning exist in the literature. We report a case of near-drowning who developed to isolated AKI due to acute tubular necrosis (ATN) requiring dialysis. A 21-yr-old man who recovered from near-drowning in freshwater 3 days earlier was admitted to our hospital with anuria and elevated level of serum creatinine. He needed five sessions of hemodialysis and then renal function recovered spontaneously. Renal biopsy confirmed ATN. We review the existing literature on near-drowning-induced AKI and discuss the possible pathogenesis.

    Retroperitoneal fibrosis has been observed in two patients with Parkinson's disease treated with bromocriptine. The patients complained of abdominal or lower back pain and presented with various degrees of renal insufficiency, with anuria in one. Laboratory evaluation furthermore showed an increased sedimentation rate and inflammatory anemia. Computerized tomography disclosed marked retroperitoneal thickening, and biopsy was performed in one patient. The symptoms appeared eighteen months and five years after treatment was started, at doses of 20 and 22.5 mg of bromocriptine daily. The medication was discontinued in both patients and steroid therapy was initiated, with resolution of all clinical, biological and radiological evidence of disease. This potential but rare complication of a widely prescribed drug warrants monitoring of renal function and sedimentation rate in patients undergoing bromocriptine treatment.

    2008-12-01

    The 2006 Kidney Disease Outcomes Quality Initiative recommended a minimum total Kt/V of 1.7, eliminated creatinine clearance (Ccr) as a target, and recommended the use of ideal body weight to calculate Kt/V. We assessed these recommendations as predictors of outcomes in anuric peritoneal dialysis patients. Retrospective observational study using administrative data. 1,432 peritoneal dialysis patients with anuria from January 1, 1994, to January 31, 2005, in a national sample (1,428 with Kt/V, 1,416 with Ccr). Kt/V and Ccr at anuria; Kt/V based on actual body weight and ideal body weight. Association of dialysis adequacy with mortality and time to first hospitalization after anuria assessed by using accelerated failure time models. 293 anuric patients had Kt/V less than 1.7, 366 had Kt/V of 1.7 to 2.0, and 769 had Kt/V greater than 2.0, using actual body weight for calculation. In unadjusted analyses, Kt/V calculated using actual body weight both less than 1.7 (-41.3%; 95% confidence interval [CI], -55.5 to -22.6) and 1.7 to 2.0 (-26.1%; 95% CI, -42.6 to -4.6) were associated with shorter time to mortality. Kt/V calculated using actual body weight less than 1.7 was associated with shorter time to hospitalization (-38.1%; 95% CI, -50.0 to -23.4), but Kt/V calculated using actual body weight of 1.7 to 2.0 was not a significant predictor (-3.3%; 95% CI, -21.1 to 18.6). After adjustment, Kt/V calculated using actual body weight less than 1.7 remained associated with mortality (-25.3%; 95% CI, -41.1 to -4.8) and hospitalization (-33.4%; 95% CI, -47.1 to -16.0). Ccr did not predict mortality. In unadjusted analysis, Ccr was not associated with hospitalization, but after adjustment, Ccr less than 50 L/wk/1.73 m(2) was significantly associated with shorter time to hospitalization (-19.9%; 95% CI, -35.0 to -1.3). Kt/V using ideal body weight was not a significant predictor in adjusted models. This study was nonrandomized, with few malnourished patients. In addition, there is

    Long-lasting recovery of renal function of the native kidneys after prolonged renal replacement therapy is rare. An 8-year-old girl and a 3-year-old boy had suffered from acute atypical and diarrhea-associated hemolytic uremic syndrome (HUS), respectively, with subsequent apparent end-stage renal failure. Both recovered renal function after long-lasting anuria and dialysis of 8 and 16 months, respectively. After prolonged follow-up, i.e., 7 and 5 years after cessation of dialysis, they attained normal or slightly reduced renal function (plasma creatinine 84 and 90 micro mol/l, respectively). In addition, growth and cognitive development were normal. We conclude that caution is appropriate before offering early renal transplantation to pediatric patients with presumed end-stage kidney disease secondary to HUS.

    To determine the utility of local thrombolysis in the treatment of acute renal arterial occlusion. We used local thrombolytic treatment in a female patient, aged 76, with 72 h of anuria, right lumbar and flank pain. She had a 3-year history of ischemic heart disease and atrial fibrillation controlled with digital treatment. Also, she was nephrectomized on the left side 33 years ago for lithiasic pyonephrosis. A normal right urinary tract was demonstrated with ultrasound examination, KUB radiography and retrograde pyelography. The next step was diagnostic abdominal angiography and local thrombolytic treatment with streptokinase. Thrombolysis with streptokinase was successful following 72 h of renal artery occlusion. After 24 months the patient is doing well. Local intra-arterial thrombolysis is the treatment of choice in renal artery occlusion.

    Full Text Available An 80-year-old man was diagnosed to have pneumonia and advanced chronic kidney disease. He presented with anuria and hemodialysis, by temporary femoral catheter, was initiated. He was empirically treated with imipenem/cilastatin 500 mg/24 h after hemodialysis. After 10 days of antibiotic intake, he developed severe diarrhea. Diagnosis of Clostridium difficile (CD-associated diarrhea was confirmed by detection of the toxins A and B in his stool. Imipenem therapy was discontinued; Vancomycin 500 mg orally every 6 h and 1000 mg per rectum every day was added. After two weeks of this treatment, the patient reported complete resolution of the diarrhea and stool samples were negative for Clostridium toxin. In this case, the most possible cause of CD colitis was considered to be imipenem because of the temporal relationship between exposure to the drug and onset of symptoms.

    A 26-year-old male bodybuilder was admitted to the surgical department of a Danish community hospital for hematemesis. During the clinical interview, he revealed that he had recently finished a course of anabolic steroids and erythropoietin. The patient also had a previous history of infections and chronic ulcers due to paraffin-oil injections in both upper arms one year before. Over the course of the next few hours, the patient developed signs of multi-organ dysfunction, including pancreatitis, hemorrhagic gastritis, nephropathy with temporary anuria, and respiratory insufficiency, and was transferred to the ICU. After manometric monitoring on the patient's upper arms proved difficult, invasive blood pressure monitoring was used and revealed that the patient was in a state of hypertensive crisis. This case of multi-organ dysfunction was possibly caused by multi-substance-induced hypercalcemia. © Georg Thieme Verlag KG Stuttgart · New York.

    1983-01-01

    Two hundred sixty-six patients were evaluated for development of acute renal function impairment after renal angiography. Forty-five (16.9%) had a significant increase in serum level of creatinine (sCr), six developed oliguria or anuria, and one required permanent dialysis. Age, proteinuria, abnormal baseline sCr, use of Renografin 76, and preexisting renal disease were the five independent risk factors in the series. An odds-ratio analysis establishes the relative risk (i.e., likelihood) of developing acute renal insufficientcy after renal angiography on the basis of the number of risk factors present. An increasing relation was demonstrated; the more factors present, the more likely it becomes that a patient will develop acute renal insufficiency

    Radiographic, historical, clinical signs, and surgical and histopathologic findings of six dogs with diagnosed cystic uterus masculinus are given. The condition was seen in aged dogs between 4 and 15 years (mean of 8.8 years). There was no breed predisposition, although the larger breeds were involved in this study. The predominant clinical signs were constipation, dysuria and anuria. Lateral survey recumbent abdominal radiographs coupled with negative-or positive-contrast cystography were useful in delineating the bladder and the urethra, thus revealing the smooth-contoured, asymmetrical fluid-filled viscus in the caudal abdomen. The bi-horned cysts were connected to the dorsal urethra through a short blind-ending pedicle. The nonseptic, aspermic, cystic fluid averaged 146.7 ml (range of 100–200 ml). The predominant epithelial lining cells seen were simple columnar to pseudostratified columnar

    Our aim was to evaluate the clinical profile, treatment, and outcome of ceftriaxone-associated postrenal acute renal failure (PARF) in children. We retrospectively studied 31 consecutive cases from 2003 to 2012 for PARF after ceftriaxone treatment. There was no past history of urolithiasis or nephropathy in these children. The average time of ceftriaxone administration before PARF was 5.2 days. The major symptoms apart from anuria included flank pain (>3 years old, 25/25), excessive crying (Ceftriaxone was verified to be the main component of the calculi in 4 children by tandem mass spectrometric analysis. The recovery was complete in all cases. Ceftriaxone therapy in children may cause PARF. Early diagnosis and prompt pharmacological therapy are important in relieving the condition. Retrograde ureteral catheterization is an effective treatment of those who fail to respond to pharmacotherapy.

    We set out to assess the effect of continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD) on residual renal function (RRF) in children with end-stage renal disease (ESRD). In 101 children (age: 8.84 +/- 5.25 years; 44 on CAPD, 57 on APD) over 36 months, we evaluated RRF [as daily diuresis (DD) in mL/kg/24 h and mL/m2/24 h], glomerular filtration rate [GFR (in mL/min/1.73 m2)], ESRD cause, presence of arterial hypertension (HTN), biochemical parameters, peritoneal equilibration test (PET), adequacy [as total weekly Kt/V (twKt/V) and creatinine clearance (twCCr)], and infectious complications of PD. Initially, the CAPD and APD groups did not differ significantly in DD, but mean GFR was significantly higher in the APD group (p uremic syndrome (HUS) and hereditary nephropathy were at the highest anuria risk. Compared with the 22 children (7 CAPD, 15 APD) who became anuric, the 20 children (10 CAPD, 10 APD) with RRF preserved for 36 months had a higher DD and GFR before dialysis onset; higher hemoglobin and albumin; and lower HTN prevalence, cholesterol, triglycerides, and proteinuria (p dialysis onset, HTN, anemia, hypoalbuminemia, hyperlipidemia, and proteinuria. Compared with children on APD, those on CAPD show better preservation of RRF during year 1, although the risk of anuria seems to be the same for both methods. In children with risk factors for rapid diuresis loss, CAPD might be considered the preferred initial dialysis method.

    The present study was conducted to analyze the dietary phosphorus intake and distribution in different food categories in peritoneal dialysis (PD) patients, to evaluate the relationship between dietary phosphorus intake and hyperphosphatemia. It was a cross-sectional study, in which prevalent Chinese PD patients were instructed by dietitians to record 3-day diet diary. Dietary phosphorus and other nutrient contents were calculated using a food composition computer program. Renal and peritoneal phosphorus clearance (CPh) was estimated, and serum phosphorus, as well as other serological parameters, were measured at the same time. 93 PD patients [age 52.9 ± 13.0 years, PD duration 30.1 (8.0, 71.0) months] finished the 3-day diet diary. Hyperphosphatemic patients (serum phosphorus level 1.97 ± 0.28 mmol/l, n = 48) showed higher dietary phosphorus intake (771.6 ± 195.1 versus 620.8 ± 155.3 mg/day, p = 0.040) than those with normal serum phosphorus level (1.37 ± 0.21 mmol/l, n = 45), due to greater phosphorus intake from meat, snacks, beverage, food condiments and additives. Significantly lower dietary phosphorus intake (605.6 ± 122.5 mg/day) and phosphorus to protein ratio (12.7 ± 1.4 mg/g) were observed in patients with anuria who maintained serum phosphorus within normal range. Multivariate linear regression analysis indicated normalized phosphorus intake, renal CPh and dietary protein intake were independently associated with serum phosphorus level. High dietary phosphorus intake is associated with elevated serum phosphorus level in PD patients. The study suggests that PD patients, particularly those with anuria, shall limit the intake of meat, snacks, beverage, food condiments and additives to reduce dietary phosphorus ingestion.

    Sixteen infants, 2 to 35 days of age, had acute renal failure, a diagnosis based on serum creatinine concentrations greater than 1.5 mg/dL for at least 24 hours. Eight infants were oliguric (urine flow less than 1.0 mL/kg/h) whereas the remainder were nonoliguric. To determine clinical parameters useful in prognosis, urine flow rate, duration of anuria, peak serum creatinine, urea (BUN) concentration, and nuclide uptake by scintigraphy were correlated with recovery. Nine infants had acute renal failure secondary to perinatal asphyxia, three had acute renal failure as a result of congenital cardiovascular disease, and four had major renal anomalies. Four oliguric patients died: three of renal failure and one of heart failure. All nonoliguric infants survived with mean follow-up serum creatinine concentration of 0.8 +/- 0.5 (SD) mg/dL whereas that of oliguric survivors was 0.6 +/- 0.3 mg/dL. Peak serum creatinine concentration did not differ between those patients who were dying and those recovering. All infants who were dying remained anuric at least four days and revealed no renal uptake of nuclide. Eleven survivors were anuric three days or less, and renal perfusion was detectable by scintigraphy in each case. However, the remaining survivor (with bilateral renal vein thrombosis) recovered after 15 days of anuria despite nonvisualization of kidneys by scintigraphy. In neonates with ischemic acute renal failure, lack of oliguria and the presence of identifiable renal uptake of nuclide suggest a favorable prognosis

    Full Text Available In this paper we describe the causes, patterns of presentation, and management of obstructive uropathy in Sudanese patients in a retrospective multi-center audit. All patients who presented with obstructive uropathy during 2005 were included in this study. All of the patients were subjected to serial investigations including imaging and tests of renal function. Diversion, stenting, and/or definitive surgery were performed in order to relieve the obstruction. Five hundred twenty patients were diagnosed with obstructive uropathy during this period; 345 (66% patients presented with chronic obstruction and 175 (34% with acute obstruction. Of the study patients, 210 (40% presented with significant renal impairment; 50 (23% of them required emergent dialysis. The patterns of clinical presentation of the obstructed patients included pain at the site of obstruction in 48%, lower urinary tract symptoms in 42%, urine retention in 36.5%, mass effect in 22%, and anuria in 4%. Patients in the pediatric age group constituted 4% of the total. The common causative factors of obstruction included congenital urethral valves, pelvi-ureteral junction obstruction, urolithiasis, and iatrogenic trauma, especially in the obstetric practice. Renal function was completely recovered with early management in 100% of patients with acute obstruction and was stabilized in 90% of patients with chronic obstruction. Four patients were diagnosed with end-stage renal failure; two of them were transplanted. The mortality rate in this study was less than 0.3%.

    In this paper we describe the causes, patterns of presentation, and management of obstructive uropathy in Sudanese patients in a retrospective multi-center audit. All patients who presented with obstructive uropathy during 2005 were included in this study. All of the patients were subjected to serial investigations including imaging and tests of renal function. Diversion, stenting, and/or definitive surgery were performed in order to relieve the obstruction.

    Objective: To investigate the significance of renal arterial embolization nephrectomy for treating post-transplanted renal failure. Methods: 15 cases of post-transplanted renal failure received renal arterial embolization. The post-procedural efficacies were followed up for about 6 months to 4 years. Results: Among the 15 cases, 11 showed blood pressure decreasing to normal level, 3 with reduction of the drug dose for anti-hypertension and 1 of no response. In addition, 12 suffered from postprocedural anuria, and 3 with obvious hypourocrinia associated with significant decrease of proteinuia; 5 with positive lymphcytic population response antigen (PRA > 20%), but turning negative with 3 of them after 3 weeks. All the transplanted kidneys revealed different degrees of atrophy but 4 of them obtained chances of successful retransplantation 3- 6 months after the procedure, 3 of them with follow up of 1-3 years were being well. Conclusions: Renal arterial embolization is a safe, efficient measure for treating post-transplanted renal failure with obvious decrease of correlative clinical symptoms and providing conditions for renal retransplantation.

    The successful endovascular repair of a type III thoracoabdominal aortic aneurysm (TAAA) with the use of a tube endograft is reported. A 56-year-old male with a 6.4-cm type III TAAA, a 4.2-cm infrarenal abdominal aortic aneurysm, and chronic renal insufficiency presented with flank pain, nausea, acute anuria, and serum creatinine of 6.1 mg/dl. Acute occlusion of the left solitary renal artery was diagnosed and emergent recanalization with percutaneus transluminal angioplasty and stenting was performed successfully, with reversal of the serum creatinine level at 1.6 mg/dl. Further imaging studies for TAAA management revealed ostial occlusion of both the celiac artery (CA) and the superior mesenteric artery (SMA) but a hypertrophic inferior mesenteric artery (IMA) providing retrograde flow to the aforementioned vessels. This rare anatomic serendipity allowed us to repair the TAAA simply by using a two-component tube endograft without fenestrations (Zenith; William Cook, Bjaeverskov, Denmark) that covered the entire length of the aneurysm, including the CA and SMA origins, since a natural arterial bypass from the IMA to the CA and SMA already existed, affording protection from gastrointestinal ischemic complications. The patient had a fast and uneventful recovery and is currently doing well 6 months after the procedure. To our knowledge, this is the first report in the English literature of successful endovascular repair of a TAAA involving visceral arteries with the simple use of a tube endograft

    We report on a 3-year-old girl with respiratory syncytial virus (RSV) encephalitis manifested by disturbance of consciousness, conjugate eye deviation, anuria, truncal ataxia and intention tremor. T2-weighted magnetic resonance imaging (MRI) showed hyperintense areas in the cerebellar cortex. No lesion was detected in the cerebral cortex, pons or spinal cord. The hyperintense areas in the cerebellar cortex diminished with recovery from the clinical manifestations and had resolved 2 months after onset. The MRI lesions in the cerebellum were considered to be due to oedema. SPECT and positron emission tomography (PET), performed 3 months after onset, disclosed areas of hypoperfusion and hypometabolism at the same sites. One year after onset, MRI showed mild atrophy of the cerebellum. Hypoperfusion on SPECT and hypometabolism on PET remained. Neuroimaging showed that ataxia and tremor in this case were the result of cerebellitis. The patient has no neurological deficit except for mild truncal ataxia. This patient is a rare example of RSV encephalitis. (orig.)

    Acute renal failure (ARF) is reported in some severe forms of malaria such as black water fever (BWF). It is associated with a high mortality rate and can be managed effectively with adequate renal replacement. A prospective survey of children with dark urine after a malarial infection with Plasmodium falciparum was coupled with a chart review study of patients managed in the past 11 years in the Pediatrics' Kinshasa University Hospital. Eighty-nine cases of ARF were identified, but data from only 63 patients were available, of whom 44 (69.8%) had severe malaria (39 with BWF and 5 with cerebral malaria). The mean age of the patients was 8.2±1.73 years. Of the 39 cases of BWF, an association with quinine ingestion was observed in 32 children (82%). Urea and creatinine levels were elevated in all cases (135.4±88.2 and 3.83±2.81 mg/dL, respectively). Oligo-anuria was observed in 44.4%, severe metabolic acidosis (bicarbonatemetabolic acidosis were observed more often than other clinical/metabolic disturbances. Severe renal impairment remains a significant complication with a high mortality rate in low-resource settings.

    Full Text Available Aim: The present work was designed to study the incidence of obstructive urolithiasis and to apply comparative diagnosis to urine retention cases. Materials and Methods: A total of 78 non-castrated buffalo calves aging 3-11 months were included in this study, 68 calves were admitted to the Veterinary Teaching Hospital, Zagazig University, Egypt, during the study period with a history of anuria, and they were classified into three groups; intact bladder group (19 calves, uroperitoneum group (45 calves, and ruptured urethra group (4 calves. 10 apparently healthy calves were used for comparison. On the basis of history, clinical, laboratory, and ultrasonographic findings diagnosis was achieved. Results: There was a marked increase in the incidence of obstructive urolithiasis in winter season, especially in winter months of 2016. Calves within the age of 3-4 months and 6-8 months were mostly affected. Inappetence to anorexia, restlessness or depression, and abdominal distension were the most observed signs in the diseased calves. Laboratory findings revealed hemoconcentration and a significant increase in blood urea nitrogen and serum creatinine levels in all diseased groups. Hyperproteinemia, hypocalcemia, and hyperphosphatemia with electrolytes imbalance were recorded in the uroperitoneum group. Ultrasonographically, distended urinary bladder with distal acoustic enhancement revealed obstructive urolithiasis with intact bladder while anechoic fluid in abdominal cavity indicates uroperitoneum. Conclusion: On the basis of all findings, calves with intact bladder were in superior condition than those with a ruptured urethra and both were better than those with uroperitoneum.

    2013-11-01

    Shiga toxin-producing Escherichia coli (STEC) hemolytic uremic syndrome (HUS) is an important cause of acute kidney injury (AKI). The outcomes of STEC HUS have improved, and the acute mortality rate in children is 1-4%. About 70% of patients recover completely from the acute episode and the remainder have varying degrees of sequelae. Only a few retrospective studies have reviewed these patients over long periods. Methodological flaws include a lack of strict definitions, changing modes of treatment, ascertainment bias and loss of subjects to follow-up. The kidneys bear the brunt of the long-term damage: proteinuria (15-30% of cases); hypertension (5-15%); chronic kidney disease (CKD; 9-18%); and end-stage kidney disease (ESKD; 3%). A smaller number have extra-renal sequelae: colonic strictures, cholelithiasis, diabetes mellitus or brain injury. Most renal sequelae are minor abnormalities, such as treatable hypertension and/or variable proteinuria. Most of the patients who progress to ESKD do not recover normal renal function after the acute episode. Length of anuria (more than 10 days) and prolonged dialysis are the most important risk factors for a poor acute and long-term renal outcome. After the acute episode all patients must be followed for at least 5 years, and severely affected patients should be followed indefinitely if there is proteinuria, hypertension or a reduced glomerular filtration rate (GFR).

  8. Comparative study of unilateral renal tubule function using 131I-o-hippuran and sup(99m)Tc-dimercaptosuccinic acid with regard to renal depth and excretion relations

    Good agreement was found between sonographic and nuclear renal depth data. In patients with undisturbed postrenal urodynamics, the data of unilateral renal clearance obtained by DMSA and OIH are in good agreement after depth correction. With OIH, the activity measured for unilateral congestion kidneys was higher than with DMSA. However, both methods may overestimate unilateral congestion kidneys. The OIH method should be favoured in nuclear renal diagnostics. In patients with mobile kidneys, the lower function calculated for the ptotic kidney can be evaluated only after depth correction. To reduce the radiation exposure, renal depth data required for depth correction should be determined by sonographic methods. The peak/scatter method of renal depth determination cannot be employed in practice in the 131 J hippurane test; in the sup(99m)Tc-DMSA test, sufficient agreement between peak/scatter quotient and renal depth is only obtained after background correction. The result does not warrant the tedious procedure. DMSA studies of the kidneys are appropriate in the following cases: 1. Emergency studies of unilateral renal function in cases of acute anuria due to postrenal stoppage. 2. Assessment of unilateral parenchymal function in patients with mobile kidneys if the ptotic kidney cannot be imaged by sonographic processes. 3. Search for extremely displaced renal tissue. 4. Unilateral renal function studies in patients with unilateral kidney diseases if the postrenal situation and the global renal function can be assessed by other methods. (orig./MG) [de

    To determine the incidence and management of urological complications after 1200 consecutive live-donor renal transplantations, all of which were carried out in one centre; the possible risk factors and the effect on patient and graft survival were also assessed. Data were retrieved from an electronic database; the incidence of urological complications was determined, and correlated with relevant risk factors by univariate and multivariate analysis. The effect on patient and graft survival was assessed using Kaplan-Meier statistics. There were 100 complications in 96 patients (8%); urinary leaks occurred in 37, ureteric strictures in 23 and lymphoceles causing ureteric obstruction in 17. Percutaneous needle biopsy was complicated by haematuria and clot anuria in six patients. Late complications included 11 cases of stones, four of bladder malignancy and two of haemorrhagic cystitis. There was evidence that the age of the recipients (effect on the incidence of urological complications. However, their development did not influence graft or patient survival. When there is meticulous attention to the technical details, renal transplantation should incur few urological complications. Early intervention with percutaneous drainage reduces morbidity and the likelihood loss of graft function. Proper and prompt management should not affect the graft and/or the patient's survival.

    Full Text Available A 25-years old man from Zagreb, Croatia, was admitted to the University Hospital for Infectious Diseases four days after the onset of symptoms such as fever, intense pain in the calves and anuria. The patient owned a rabbit and, before the onset of the disease, repaired some rubber pipes damaged by rodents. At admission, he had a severe clinical picture with fever, hypotension, jaundice, immobility, and pain in leg muscles. Treatment with ceftriaxone was initiated in combination with volume restitution. Renal failure soon ensued. Consequently continuous venovenous hemodiaphiltration therapy was performed. Due to acute respiratory distress syndrome, the patient was mechanically ventilated. The patient’s condition gradually improved and he recovered fully from multi-organ failure. Diagnosis was confirmed by a microscopic agglutination test (MAT covering 15 leptospira serovars and real-time polymerase-chain reaction (PCR. The first serum sample taken on day 6 tested negative for leptospira, while PCR showed positive results for leptospiral DNA. The second serum sample taken on day 13 tested positive for serovar Canicola serogroup Canicola, serovar Patoc, serovar Grippotyphosa serogroup Grippotyphosa and serovar Tarassovi serogroup Tarassovi (titre 4000, 4000, 1000 and 2000, respectively, while PCR was negative. This report highlights the benefits of combining MAT and PCR methods in early diagnosis of leptospirosis.

    The authors report a series of 130 children suffering from urinary lithiasis (essentially between the age of 4 to 6 years) and particularly in boys (2.5 to 1). There were 108 cases of reno-ureteric lithiasis as against 23 vesico-urethral. In 69 cases, pyelocalyceal lithiasis predominated. Thirty per cent of the children had bilateral lithiasis, and 19% of all cases of lithiasis were staghorn calculi. Presenting symptoms : haematuria, diffuse abdominal pain, anuria (6 cases), complete urinary retention (5 cases). Study of these cases failed to indicate whether obstruction of the upper urinary tract (14%) or infection (27%) was the cause or the effect of the lithiasis. Particularly notable were 8 cases of cystinuria (6%), 1 of glycinuria, 1 of hyperoxaluria and 7 of hypercalciuria. At least in Spain, lithiasis in children would appear to be essentially idiopathic. However, 40% of these cases of lithiasis were secondary to obstruction of the excretory tract and/or urinary infection. All types of entero-uroplasty were lithogenic (6 cases). 32% of the children had a proteus infection. Treatment : 14 children were treated medically as against 125 surgically. 70% are free of any recurrence. 7% have a residual lithiasis. The rarity of recurrences and the quality of the results obtained indicate that complete surgical treatment represents the essential feature of the treatment of urinary lithiasis in children.

    Acute Kidney Injury (AKI) has a significant mortality rate. In developing countries, mortality due to AKI is high due to lack of access to dialysis facilities and related cost. The main goal of International Society of Nephrology (ISN) 0 by 25 initiative is to eliminate deaths due to AKI. Peritoneal dialysis is an underutilized modality in such a scenario. The aim of this study was to look into effectiveness of starting Acute stylet Peritoneal Dialysis (PD) in a resource constraint settings. In this prospective study conducted over a year, patients with AKI due to various aetiologies were subjected to Acute stylet PD. The clinical Outcome, demographic, biochemical and treatment data was assessed. Descriptive statistics was used to analyze the data. A total of 79 (41 anuric, 33 oliguric and 5 nonoliguric) patients were included in the study. Sepsis was the predominant cause of AKI. Recovery was seen in 34% of patients. Patients with relatively preserved urine output recovered with PD in comparison to the anuric patients (p value <0.01). 58% of patients, majority of whom were anuric needed Hemodialysis (HD) in due course (7 ± 3 days) of time. The mortality in our study was 7.5%. Acute stylet PD can be considered as a modality of Renal Replacement Therapy (RRT) to treat a selected (oliguric, nonoliguric) group of AKI patients and as a bridge therapy for HD in those AKI patients in anuria.

    Full Text Available Acute glomerulonephritis (AGN is a type of renal disease which indicates the inflammation of glomerulus and nephrons. This study was carried on 94 children, <15 years old with the diagnosis of AGN who were admitted to Qom and Yazd's hospitals between 2000 and 2006. Data were collected using hospital records on admission, progression notes and outpatient follow up. Among 94 patients, 55.3% were male and 44.6% were female. Mean age of patients was 8.2±2.7 years old. Acute post streptococcal glomerulonephritis (APSGN was reported in 92.5%, membranoproliferative glomerulonephritis in 4.2%, hemolytic uremic syndrome in 2.1% and IgA nephropathy in 1.06%. There was no significant differences between GN types and gender (P=0.54. Clinical manifestation included edema in 68.8%, oliguria in 36.3%, gross hematuria in 69.1%, HTN in 61.7% and anuria in 1.06%. Microscopic hematuria was detected in all patients. In the time of follow up none of patients had hypertension, 3.1% had proteinuria and 6.3% had microscopic hematuria. APSGN is the most common causes of AGN in Qom and Yazd's children. Early diagnosis and treatment of APSGN may protect children from long term morbidity and mortality and improve quality of life.

    Full Text Available Abstract. We report the case of a patient with long-term history of hypertension, presenting with transient neurological disorders and severe graft failure several years after kidney transplantation. Cause of end-stage renal disease was hypertensive nephrosclerosis. Chronic hemodialysis lasted for 1 year. After transplantation and throughout follow-up, serum creatinine ranged from 200 to 230 μmol/L and maintenance immunosuppression included sirolimus and low-dose steroids. Six years after transplantation, the patient presented with right hip pain radiating to the lower back, transient aphasia, confusion, and hemiparesis. Surprisingly, progressive anuria was established requiring dialysis. After numerous nonconclusive investigations including renal histology, a contrast computed tomography scan discovered a Stanford B aortic dissection from the left common carotid artery and left subclavian artery to bilateral internal and external iliac arteries, including the right femoral artery. No surgical treatment was opted and hemodialysis, tight control of blood pressure and oral anticoagulation were established. Immunosuppression was lightened to low-dose steroids alone. After 8 months, chronic dialysis was stopped, and today, 22 months after the diagnosis of aortic dissection, the patient is doing well with a still functioning graft (creatinine, 377 μmol/L; modification of diet in renal disease-glomerular filtration rate, 15 mL/min, and without any other immunosuppression than low-dose steroids.

    Rhabdomyolysis is a rare paediatric condition. The case is presented of a patient in whom this developed secondary to severe hypernatraemic dehydration following acute diarrhoea. Infant 11 months of age who presented with vomiting, fever, diarrhoea and anuria for 15 hours. Parents reported adequate preparation of artificial formula and oral rehydration solution. He was admitted with malaise, severe dehydration signs and symptoms, cyanosis, and low reactivity. The laboratory tests highlighted severe metabolic acidosis, hypernatraemia and pre-renal kidney failure (Sodium [Na] plasma 181 mEq/L, urine density> 1030). He was managed in Intensive Care Unit with gradual clinical and renal function improvement. On the third day, slight axial hypotonia and elevated cell lysis enzymes (creatine phosphokinase 75,076 IU/L) were observed, interpreted as rhabdomyolysis. He was treated with intravenous rehydration up to 1.5 times the basal requirements, and he showed a good clinical and biochemical response, being discharged 12 days after admission without motor sequelae. Severe hypernatraemia is described as a rare cause of rhabdomyolysis and renal failure. In critically ill patients, it is important to have a high index of suspicion for rhabdomyolysis and performing serial determinations of creatine phosphokinase for early detection and treatment.

    Abdominal aortic aneurysms can be complicated by some conditions and aortocaval fistula is one of them. Aortocaval fistula is an unusual entity. A male patient was admitted to the hospital for abdominal pain and leg oedema of three days duration. In addition, severe anuria was also noted. We determined a fistula from the right lateral wall of aneurysm to the distal of vena cava inferior. The aortocaval fistula was closed with pledged-reinforced 4/0 polypropylene suture in the aneurysmal wall. At the postoperative 10th day, he was discharged with normal renal function. After a long-term untreated fistula, right-sided heart failure, acute renal and hepatic insufficiency, deep vein thrombosis and pulmonary thrombo-embolism can be seen in these patients. Increased venous pressure should be the reason for decreased arterial flow results in renal insufficiency. Emergency intervention in these patients saves the patient's life as well as prevents irreversible organ failure. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Chronic dialysis is a valid therapeutic option in very elderly ESRD patients, even though the decision to dialyze or not has little impact on survival. Additionally, very old patients usually do not agree with starting chronic dialysis. Even though, activated charcoal is a cheap treatment for working as adsorbent for nitrogenous products its utility is very limited. We studied the combination of a low protein diet and oral activated charcoal to reduce serum urea and creatinine levels in very old ESRD patients who had refused to start chronic dialysis. Nine lucid, very old > 80 years, ESRD patients who had refused to start dialysis were prescribed a treatment based on a combination of a very low protein diet and oral activated charcoal (30 gram/day). None of the patients had anuria, oliguria, edema, significant metabolic acidosis or hyperkalemia. None of them had significant gastrointestinal symptoms. After one week and ten months of charcoal use significant decrease in blood urea and creatinine levels was observed and none of them required emergency dialysis during this time. In conclusion, in patients more than 80 years of age low protein diet and oral activated charcoal may control the uremic symptoms effectively.

    A clinical case of a 72 hours newborn patient admitted to the pediatric intensive care unit for reduced cardiac output syndrome showing anuria, metabolic acidosis and respiratory distress, is reported. Mechanical ventilation, inotropic support and continuous prostaglandin e1 infusion were initiated. The echocardiogram showed hypoplasia of the left ventricle. The Norwood procedure stage i under extracorporeal circulation with deep hypothermia and circulatory arrest, was performed at the 6th day of life. During the early postoperative period, the patient developed hypoxaemia and pulmonary hypertension, which improved with controlled hyperventilation and vasodilatation therapy. Other complications were clinical sepsis and abstinence syndrome, which resolved with medical management. The patient was extubated on the sixth postoperative day. Subsequent echocardiograms showed tricuspid valve regurgitation, right ventricular dysfunction with dilation and an organized thrombus in the left atrium. These improved with diuretics, dopamine, milrinone and heparin. The patient was discharged after 32 days of the surgery without signs of congestive heart failure. This case is important, given the high mortality rate of this pathology. The Norwood procedure proved to be a palliative strategy versus the ortotopic cardiac transplant in newborns, because of the difficulty in finding donators at this age and the immunosuppressive therapy complications. This represents a great advance in the Colombian pediatric cardiology because until recent years these patients did not have any other surgical alternative

    The authors developed a cost-effective approach to imaging studies, based on initial selection of an exam that best addresses the specific clinical problem and obviates the need for additional diagnostic tests. Tightly reasoned arguments compare available imaging options with respect to diagnostic yield, feasibility, risk, and cost. To aid the clinician in making cost comparisons, each paper of the Second Edition lists the dollar cost of relevant imaging studies. The Second Edition has been thoroughly revised to reflect the important advances in diagnostic imaging of the past three years, highlighting CT's expanding role in thoracic and abdominal problems, magnetic resonance imaging as a spectacular diagnostic tool for the central nervous system, and the clinical application of many newly-developed radiopharmaceuticals. New chapters cover breast cancer screening, acute spinal trauma, search for primary cancer of unknown origin, acute anuria, blunt chest trauma, new onset seizures, and spinal cord compression from metastases. Other papers have been rewritten for greater clarity and to incorporate new techniques, like dipyridamole stress testing.

    A 58-year-old man was referred to our hospital with high fever and anuria. Since undergoing a total pelvic exenteration due to bladder-invasive sigmoid colon cancer, urinary tract infections had frequently occurred. We treated with the construction of a bilateral percutaneous nephrostomy (PCN), and chemotherapy. Although we replaced the PCN with a single J ureteral catheter after an improvement of infection, urinary infection recurred because of an obstruction of the catheter. Urological examinations showed that an ileal conduit-ureteral reflux caused by kinking of the ileal loop was the reason why frequent pyelonephritis occurred. We decided to resect the proximal segment to improve conduit-ureteral reflux for the resistant pyelonephritis. After the surgery, the excretory urogram showed improvement and the urinary retention at the ileal conduit disappeared. Three years after the operation, renal function has been stable without episodes of pyelonephritis. Here we report a case of open repair surgery of an ileal conduit in a patient with severe urinary infection.

    Radionuclide renal studies are particularly well suited to pediatrics as renal problems in children usually are part of a dynamic process which requires serial assessment. The absence of side-effects and the low radiation dose has added to their popularity in pediatrics. A number of different renal parameters can be evaluated using the appropriate radiopharmaceutical and method of analysis. The renal study is of value to assess patients with hydronephrosis both pre-operatively and for serial follow-up post-operatively, as well as to distinguish obstructive from non-obstructive uropathy. Perfusion to the kidney may be assessed and ischemic areas detected in children with hypertension or trauma. The renal scan commonly is used in patients with congenital anomalies such as ectopic and duplex kidneys, nonvisualized kidney on IVP and in children with oliguria or anuria secondary to diseases such as acute tubular necrosis, hemolytic uremic syndrome, and renal vein thrombosis. It frequently is done as an emergency procedure in neonates. In conjunction with the IVP and ultrasound, the renal study is useful in some cases of abdominal mass to distinguish between hydronephrosis, cystic kidneys and tumors

    Acute kidney injury (AKI) with hyperparathyroidism caused by nitrite was rare, and renal function and parathyroid hormone (PTH) decreased to normal range after therapy. Acute kidney injury was diagnosed in a 40-year-old male with hyperparathyroidism and cyanosis of his hands and both forearms. The patient ate some recently pickled vegetables, and he experienced nausea, vomiting and diarrhoea without oliguria or anuria; Additionally, his hands and both forearms had a typical blue ash appearance. After admission, the laboratory findings indicated theincreasing serum creatinine (Scr) and parathyroid hormone (PTH). He was diagnosed as acute kidney injury with hyperparathyroidism caused by nitrite. The patient stopped eating the pickled vegetables and was given rehydration, added calories and other supportive therapy without any glucocorticoids. According to his clinical manifestations, laboratory findings and imaging results, the patient was diagnosed with acute kidney injury with secondary hyperparathyroidism. He was given symptomatic supportive care therapy. After one week, the serum creatinine, parathyroid hormone (PTH), hypercalcemia, hyperphosphatemia, proteinuria, and urine red blood cell values decreased to normal range. Nitrite-induced acute kidney injury with secondary hyperparathyroidism was relatively rare. After therapy, the function of the kidney and parathyroid returned to normal. This case suggests that detailed collection of medical history, physical examination and correct symptomatic treatment is very important.

    Full Text Available Abstract Background Acute aortic dissection (AAD is a life-threatening condition requiring immediate assessment and therapy. A patient suffering from AAD often presents with an insignificant or irrelevant medical history, giving rise to possible misdiagnosis. The aim of this retrospective study is to address the problem of misdiagnosing AD and the different imaging studies used. Methods From January 2000 to December 2004, 49 patients (41 men and 8 women, aged from 18–75 years old presented to the Emergency Department of our hospital for different reasons and finally diagnosed with AAD. Fifteen of those patients suffered from arterial hypertension, one from giant cell arteritis and another patient from Marfan's syndrome. The diagnosis of AAD was made by chest X-ray, contrast enhanced computed tomography (CT, transthoracic echocardiography (TTE and coronary angiography. Results Initial misdiagnosis occurred in fifteen patients (31% later found to be suffering from AAD. The misdiagnosis was myocardial infarction in 12 patients and cerebral infarction in another three patients. Conclusion Aortic dissection may present with a variety of clinical manifestations, like syncope, chest pain, anuria, pulse deficits, abdominal pain, back pain, or acute congestive heart failure. Nearly a third of the patients found to be suffering from AD, were initially otherwise diagnosed. Key in the management of acute aortic dissection is to maintain a high level of suspicion for this diagnosis.

    A clinical and epidemiological study of 267 cases of envenomation by Loxosceles spp. (loxoscelism), notified to Centro de Informações Toxicológicas de Florianópolis (Santa Catarina State, Brazil), was conducted between January 1985 and December 1995. Most of the incidents occurred along the coast of the mid-southern region of the state, during the warmest months. L. laeta and L. intermedia were identified as the causative agents. Cutaneous loxoscelism was clinically diagnosed in 232 (86.9%) patients with local pain (86.5%), oedema (80.5%), hyperaemia (79.8%) and necrosis (56.9%). Cutaneous-visceral loxoscelism was detected in 35 patients (13.1%) with intravascular haemolysis, manifested by jaundice (68.6%), oliguria (45.7%), dark urine (28.6%), haemorrhage (25.7%), anuria (8.6%) and shock (2.9%), besides the cutaneous effects. Specific antivenom was given to 125 patients (46.8%) and only 8 (6.5%) had mild reactions. Acute renal failure was observed in 17 cases (6.4%); 4 patients (1.5%) died, all of whom were children under 14 years old.

    To analyse 80-kVp 16-MDCT in patients with clinically suspected pulmonary embolism (PE) and diminished renal function after a reduction in dose of contrast medium (CM) from 200 to 150 mg I/kg. Fifty patients with suspected PE and glomerular filtration rate (GFR) less than 50 mL/min underwent 80-kVp 16-MDCT with 150 mg I/kg. Mean density/image noise (1 standard deviation) was measured in a region of interest in the left pulmonary artery (LPA) and a lower lobe segmental artery (LLSA), and the contrast-to-noise ratio (CNR) was calculated. The values of LPA and LLSA were averaged. Median values/2.5-97.5 percentiles were: age 84/67-96 years, weight 65/43-84 kg, GFR 36/21-45 mL/min, CM dose 9.6/6.4-12 g of iodine, PA density 353/164-495 HU and CNR 11/4.4-20. PE incidence was 16%, and 8% and 12% of the examinations were regarded suboptimal by observer 1 and 2, respectively. Density/CNR values were within ranges reported for common 120-kVp MDCT protocols. None of 32 patients with plasma-creatinine follow-up within 1 week experienced a rise of more than 44.2 {mu}mol/L and none of 50 patients had oliguria/anuria or dialysis. None of 40 patients with a negative CT/no anticoagulation had thromboembolism during follow-up. 80-kVp MDCT combined with individualised ultralow CM doses may provide satisfactory diagnostic quality, which should be to the benefit of patients at risk of contrast medium-induced nephropathy.

    Retention of β 2-microglobulin in patients undergoing hemodialysis is associated with a β 2-microglobulin-derived amyloidosis. Removal of β 2-microglobulin by renal replacement therapy has been proposed for the prevention of this amyloidosis. Currently, however, data on the β 2-microglobulin synthesis rate in patients undergoing hemodialysis are scarce, and consequently it remains speculative how much removal would be necessary to counterbalance synthesis. The plasma kinetics of iodine 131-labeled β 2-microglobulin were therefore examined in 11 patients with anuria who were undergoing long-term hemodialysis. Five healthy persons served as controls. Kinetic modeling of the plasma curves showed that the data fitted a two-pool model (r2 greater than 0.96) consisting of a rapid 2 to 4 hour distribution phase followed by a less steep curve, described by the plasma (metabolic) clearance (Clp). Synthetic rates were calculated from Clp and the β 2-microglobulin steady state plasma concentration (plus β 2-microglobulin removal during hemodialysis in the case of high flux hemodialysis). The results showed a significantly higher Clp in normal controls as compared with patients undergoing hemodialysis (65.5 ± 12.8 ml/min (mean ± SD) versus 3.4 ± 0.7 ml/min). In contrast, the β 2-microglobulin synthesis rate in the patient group (3.10 ± 0.79 mg/kg/day) was not significantly different from that of normal controls (2.40 ± 0.67 mg/kg/day), which was due to markedly elevated β 2-microglobulin plasma concentrations in the patients (37.6 ± 14.1 mg/L vs 1.92 ± 0.27 mg/L). These findings suggest that the presence of end-stage renal disease does not have a significant impact on the beta 2-microglobulin generation rate

    Augmented renal clearance (ARC) refers to the enhanced renal excretion of circulating solute commonly demonstrated in numerous critically ill subgroups. This study aimed to describe the prevalence of ARC in critically ill Indigenous Australian patients and explore the accuracy of commonly employed mathematical estimates of glomerular filtration. We completed a single-centre, prospective, observational study in the intensive care unit (ICU), Alice Springs Hospital, Central Australia. Participants were critically ill adult Indigenous and non-Indigenous Australian patients with a urinary catheter in situ. Exclusion criteria were anuria, pregnancy or the requirement for renal replacement therapy. Daily eight-hour measured creatinine clearances (CrCLm) were collected throughout the ICU stay. ARC was defined by a CrCLm ≥130 ml/min/1.73 m2. The Cockcroft-Gault and Chronic Kidney Disease Epidemiology Collaboration equations were also used to calculate mathematical estimates for comparison. In total, 131 patients were recruited (97 Indigenous, 34 non-Indigenous) and 445 samples were collected. The median (range) CrCLm was 93.0 (5.14 to 205.2) and 90.4 (18.7 to 206.8) ml/min/1.73 m2 in Indigenous and non-Indigenous patients, respectively. Thirty-one of 97 (32%) Indigenous patients manifested ARC, compared to 7 of 34 (21%) non-Indigenous patients (P=0.21). Younger age, major surgery, higher baseline renal function and an absence of diabetes were all associated with ARC. Both mathematical estimates manifest limited accuracy. ARC was prevalent in critically ill Indigenous patients, which places them at significant risk of underdosing with renally excreted drugs. CrCLm should be obtained wherever possible to ensure accurate dosing.

    Full Text Available Acute renal failure (ARF is reported in some severe forms of malaria such as black water fever (BWF. It is associated with a high mortality rate and can be managed effectively with adequate renal replacement. A prospective survey of children with dark urine after a malarial infection with Plasmodium falciparum was coupled with a chart review study of patients managed in the past 11 years in the Pediatrics′ Kinshasa University Hospital. Eighty-nine cases of ARF were identified, but data from only 63 patients were available, of whom 44 (69.8% had severe malaria (39 with BWF and 5 with cerebral malaria. The mean age of the patients was 8.2 ± 1.73 years. Of the 39 cases of BWF, an association with quinine ingestion was observed in 32 children (82%. Urea and creatinine levels were elevated in all cases (135.4 ± 88.2 and 3.83 ± 2.81 mg/dL, respectively. Oligo-anuria was observed in 44.4%, severe metabolic acidosis (bicarbonate <15 mEq/L in 61.5% and hyponatremia (<130 mEq/L in 33.3%. Peritoneal dialysis was required in 36 patients, including 20 with BWF. The remaining patients were managed with conservative treatment. Twenty-eight children (44.4%, including 20 on dialysis, fully recovered and 14 died (22.2%, including eight cases of BWF. Our study suggests that ARF is commonly associated with BWF in Congolese children. Elevated urea and creatinine and severe metabolic acidosis were observed more often than other clinical/metabolic disturbances. Severe renal impairment remains a significant complication with a high mortality rate in low-resource settings.

    Decreased physical activity in mammals increases bone turnover and uncouples bone formation from bone resorption, leading to hypercalcemia, hypercalcuria, bone loss and increased fracture risk. Black bears, however, are physically inactive for up to 6 months annually during hibernation without losing cortical or trabecular bone mass. Bears have been shown to preserve trabecular bone volume and architectural parameters and cortical bone strength, porosity and geometrical properties during hibernation. The mechanisms that prevent disuse osteoporosis in bears are unclear as previous studies using histological and serum markers of bone remodeling show conflicting results. However, previous studies used serum markers of bone remodeling that are known to accumulate with decreased renal function, which bears have during hibernation. Therefore, we measured serum bone remodeling markers (BSALP and TRACP) that do not accumulate with decreased renal function, in addition to the concentrations of serum calcium and hormones involved in regulating bone remodeling in hibernating and active bears. Bone resorption and formation markers were decreased during hibernation compared with when bears were physically active, and these findings were supported by histomorphometric analyses of bone biopsies. The serum concentration of cocaine and amphetamine regulated transcript (CART), a hormone known to reduce bone resorption, was 15-fold higher during hibernation. Serum calcium concentration was unchanged between hibernation and non-hibernation seasons. Suppressed and balanced bone resorption and formation in hibernating bears contributes to energy conservation, eucalcemia and the preservation of bone mass and strength, allowing bears to survive prolonged periods of extreme environmental conditions, nutritional deprivation and anuria. © 2015.

    To report a case of a newborn patient with renal failure due to polycystic kidneys requiring renal replacement therapy, and total anomalous pulmonary venous return requiring major cardiosurgical intervention. Pediatric cardiosurgery operatory room and pediatric cardiologic intensive care. A 6-day-old newborn child weighing 3.1 kg. Renal function (creatinine value and urine output) was monitored during the course of the operation and intraoperative renal replacement therapy was not initiated. Serum creatinine concentration decreased from 4.4 to 3 mg/dL at cardiopulmonary bypass (CPB) start and to 1.5 at the end of surgery: the creatinine decrease was provided by the dilutional effect of CPB priming and the infusion of fresh blood from transfusions together with an adequate filtration rate (800 m/L in about 120 minutes). After the operation, extracorporeal membrane oxygenation (ECMO) for ventricular dysfunction and continuous hemofiltration for anuria refractory to medical therapy were prescribed. The hemofiltration machine was set in parallel with the ECMO machine at a blood flow rate of 60 ml/min and a predilution replacement solution infusion of 600 ml/h (4.5 ml/min of creatinine clearance once adjusted on extracorporeal circuits; 3000 mL/m2 hemofiltration): after a single hemofiltration session lasting 96 hours, serum creatinine reached optimal steady state levels around 0.5 mg/dL on postoperative day 2 and 3. Administration of intraoperative continuous hemofiltration is not mandatory in the case of a 3-kg newborn patient with established renal failure needing major cardiosurgery: hemodilution secondary to CPB, transfusion of hemoderivates, and optimal UF rate appear to be effective methods for achieving solute removal. If postoperative continuous hemofiltration is started, however, a "dialytic dose" of 4.5 ml/min allows an adequate creatinine clearance, quick achievement of a steady state of serum creatinine concentration and an eventual acceptable rate of

    Full Text Available Obiectives: To report our experience of diagnosis and multimodal management of urolithiasis in renal transplantation. Patients and Methods: From January 1995 to December 2012, 953 patients underwent renal transplantation in the Kidney Transplant Unit of Treviso General Hospital. Ten (10% of them developed urinary calculi and were referred at our institution. Their mode of presentation, investigation and treatment were recorded. Results: Seven had renal and 3 ureteral calculi. Urolithiasis was incidentally discovered on routine ultrasound in 6 patients, 1 presented with oliguria, 1 with anuria and acute renal failure and in 2 urolithiasis was found at removal of the ureteral stent. Nephrostomy tube was placed in 5 patients. Hypercalcemia with hyperparathyroidism (HPT was present in 5 patients and hyperuricemia in 3. Two patients were primary treated by shock wave lithotripsy (SWL and one of them was stone-free after two sessions. Two patients, one with multiple pielocaliceal calculi and the other with staghorn calculus in the lower calyx, were treated with percutaneous nephrolitothotomy (PCNL. Three patients were treated by ureteroscopy (URS and in one of them two treatments were carried out. One patient had calculus impacted in the uretero-vesical anastomosis and surgical ureterolithotomy with re-do ureterocystoneostomy was performed after failure of URS. Two patients with calculi discovered at removal of the ureteral stent were treated by URS. Conclusions: The incidence of urolithiasis in renal transplantation is uncommon. In the most of patients the condition occurs without pain. Metabolic anomalies and medical treatment after renal transplantation may cause stone formation. Advancements in endourology and interventional radiology have influenced the management of urolithiasis that can be actually treated with a minimal incidence of risk for the renal allograft.

    In 2011 Escherichia coli O104:H4 caused an outbreak with >800 cases of hemolytic uremic syndrome (HUS) in Germany, including 90 children. Data on the intermediate outcome in children after HUS due to E. coli O104:H4 have been lacking. Follow-up data were gathered retrospectively from the medical records of patients who had been included in the German Pediatric HUS Registry during the 2011 outbreak. Seventy-two of the 89 (81%) patients were included after a median follow-up of 3.0 (0.9-4.7) years. Hypertension and proteinuria were present in 19% and 28% of these patients, respectively. Of 4 patients with chronic kidney disease (CKD) > stage 2 at short-term follow-up, 1 had a normalized estimated glomerular filtration rate, and 3 (4%) had persistent CKD > stage 2. In 1 of these patients, CKD improved from stage 4 to 3; 1 who had CKD stage 5 at presentation received kidney transplantation; and 1 patient required further hemodialysis during follow-up. One patient (1.4%) still had major neurological symptoms at the latest follow-up. Dialysis during the acute phase (P = .01), dialysis duration (P = .01), and the duration of oligo-/anuria (P = .005) were associated with the development of renal sequelae. Patients treated with eculizumab (n = 11) and/or plasmapheresis (n = 13) during the acute phase of HUS had comparable outcomes. The overall outcome of pediatric patients after HUS due to E. coli O104:H4 was equivalent to previous reports on HUS due to other types of Shiga toxin-producing E. coli (STEC). Regular follow-up visits in patients are recommended after STEC-HUS. © The Author 2017. Published by Oxford University Press for the Infectious Diseases Society of America. All rights reserved.

    Rizwan, N.

    2011-01-01

    Acute renal failure (ARF) is a syndrome characterised by rapid decline in glomerular filtration rate and retention of nitrogenous waste products such as urea and creatinine. The objective of this study was to study the prevalence, risk and outcome of women with obstetrical renal failure. Methods: This observational study was conducted in Department of Obstetrics and Gynaecology, Liaquat University Hospital, Hyderabad, Pakistan from October 2009 to September 2010. Thirty-five patients with obstetrical acute renal failure were included in the study, patients with chronic renal diseases, hypertension, diabetes mellitus and renal stones were excluded from the study. A detailed history was followed by thorough examination and investigation. Their clinical history, physical examination and intake/urine output was recorded. Routine laboratory investigations were done related to each case and specialised investigations like renal scan, renal ultrasonography and renal biopsies were performed in selected cases where recovery was delayed for more than 3 weeks. Results: Total numbers of admissions in obstetric ward were 3,285. Pregnancy related acute renal failure was found in 35 (1.065%) women. Age ranged from 18-40 years. Most of the women belonged to age group 30-35. Out of 35 women 31.42% had postpartum haemorrhage. Ante partum haemorrhage was found in 25.71%, Eclampsia in 17.14%, DIC in 14.28%, and sepsis in 11.42%. Anuria was observed in 25 patients, remaining presented with oliguria (28.57%). Haemodialysis was done in 75% of patients, others were managed conservatively. Complete recovery was observed in 53% cases. Maternal mortality was 25.71% and foetal mortality was 22.85%. Conclusion: Pregnancy related ARF is one of the most common causes of ARF, it is a dangerous complication of pregnancy which carries very high mortality and morbidity. (author)

    2004-01-01

    Objective: To identify the causes of acute renal failure (ARF) in pediatric population along with the identification of the age and gender most affected by the failure. Subjects and Methods: The study included children under the age of 12 years who presented with signs and symptoms suggestive of ARF (oliguria/anuria, vomiting, acidotic breathing etc.) along with raised blood urea nitrogen (BUN) serum creatinine and metabolic acidosis as shown by arterial blood gases (ABGs). Patients were divided into two group on the basis of age; group A consisting of 0-2 years and group B from >2 years. Patients presenting with transient pre-renal azotaemia were excluded from the study. After providing initial emergency cover, detailed history, physical examination and investigations were carried out according to a proforma specially designed to ascertain the cause of ARF. Patients were managed for ARF as per standard recommendations and investigations completed or repeated as and when required. Results: A total of 119 patients with ARF were admitted in the ward over a period of two years constituting 1.36% of the total admissions and 16.39% of the admissions due to renal pathology. Mean age of presentation was 4.5 years 16.7% of the patients under the age of 5 years. Male predominance was noted in all ages with an overall male to female ratio of 2.3:1. Most common cause leading to ARF in younger age group was found to be hemolytic uremic syndrome [25(54.34%)] followed by septicemia [7(15.21 %)]. In older patients renal calculus disease was the most common [22(30.13%)] underlying pathology followed by pre-existing, undiagnosed chronic renal failure [16(21.91 %)]. Conclusion: ARF is fairly cotton in children especially under the age of 5 years showing a male predominance. More than 90% of the cases can be prevented by improving primary health care and by early and prompt treatment of infections. (author)

    2012-09-01

    Full Text Available Background and Aim. Advanced chronic kidney disease (CKD severely impairs life expectancy and quality of life in affected patients. Considering its benefits, renal transplantation currently represents the optimal treatment solution for end stage kidney disease patients. Pre-transplant assessment aims to maximize the graft and patient survival by identifying potential factors influencing the post-transplant outcome. The aim of this study has been to analyze recipient related prognostic factors bearing an impact on graft survival. Material and Methods. We analyzed the graft outcomes of 426 renal transplantations performed at the Clinical Institute of Urology and Renal Transplantation of Cluj-Napoca, between January 2004 and December 2008. Variables related to recipient and to potential donor/recipient prognostic factors were studied using univariate and multivariate analysis. Results. Graft survivals at 1, 3, 5 and 7 years were 94.01%, 88.37%, 82.51% and 78.10%, respectively. Chronic rejection (41.11% and death with a functioning graft (18.88% were the main causes of graft loss. In uni and multivariate analysis the recipient related variables found to influence the renal graft outcome were: peritoneal dialysis, pre transplant residual diuresis, grade I hypertension, severe iliac vessel atheromatosis, ischemic heart disease, stroke history, dyslipidemia and denutrition. The worst graft outcomes have been found for recipients on peritoneal dialysis, with anuria, hypotension, severe iliac atheromatosis, ischemic heart disease, stroke history, dyslipidemia and a poor nutritional status. Conclusion. The type of dialysis, the pre transplant residual diuresis, recipient arterial blood pressure, iliac vessel atheromatosis, ischemic heart disease, stroke history, dyslipidemia and denutrition significantly influence graft survival.

  17. Hypertonic saline solution and high-dose furosemide infusion in cardiorenal syndrome: our experience

    2013-03-01

    Full Text Available Introduction Heart failure is frequently complicated by renal failure, and this association is a negative prognostic factor. These patients sometimes present oligo-/anuria and resistance to high-dose furosemide, a condition referred to as the cardiorenal syndrome (CRS. Acute or chronic reductions in left ventricular function result in decreased blood flow, with reduction of renal perfusion and activation of several neurohormonal systems, which cause resistance to diuretic therapy. This condition often requires ultrafiltration, which is an effective, but invasive and expensive procedure. Infusions of hypertonic saline solution (HSS and high-dose furosemide can be an effective alternative. Materials and methods From November 2009 through May 2010, our team treated 20 patients with CRS and resistance to iv boluses of high-dose furosemide. These patients were treated with small-volume (150-250 mL infusions of HSS (NaCl 1.57 – 4.5%, depending on serum Na values and high-dose furosemide twice a day. The aim of this treatment is to modify renal hemodynamics and the water-saline balance in the kidney by counteracting the extracellular fluid accumulation and eliminating symptoms of congestion. Results In 18 patients (90%, urine output was restored and renal function improved during the first hours of treatment. Clinical improvement was evident from the first day of therapy, and there were no adverse events. Two patients (10% did not respond to the treatment: one (who had been in critical condition since admission died; the other required regular sessions of ultrafiltration. Conclusions HSS combined with high-dose furosemide is a safe, effective, low-cost approach to the treatment of CRS that is resistant to diuretic therapy.

    Objective: To describe the clinical spectrum and outcome of patients presenting to a tertiary care kidney center, developing acute kidney injury (AKI) after snake-bite. Study Design: An observational study. Place and Duration of Study: Nephrology Department, Sindh Institute of Urology and Transplantation (SIUT), Karachi, from January 1990 to December 2014. Methodology: All patients coming to SIUT identified as having AKI after snake-bite during the study period were included. AKI was defined according to RIFLE criteria with sudden rise in creatinine or decline in urine output or both. Demographics, clinical presentation, laboratory profile, and final outcome was noted. Result: During the studied period, 115 cases of AKI, secondary to snake-bite, were registered at this institution. Median age of patients was 35.92 ±15.04 (range: 6 - 70) years and male to female ratio was 1.6:1. Time from bite and referral to this hospital ranged from 2 to 28 days (mean: 8.77 ±5.58 days). Oligo-anuria was the most common presentation, being found in 98 (93.90 percentage) patients. Bleeding diathesis was reported in 75 (65.21 percentage) patients on presentation. All patients had normal sized, non-obstructed kidneys on ultrasonography, with no previous comorbids. Renal replacement therapy (RRT) was required in 106 (92.17 percentage) patients. Complete recovery was seen in 59 (51.30 percentage), while 15 (13.04 percentage) patients expired during acute phase of illness, 4 (3.47 percentage) developed CKD, 11 (9.56 percentage) required dialysis beyond 90 days, and 26 (22.60 percentage) were lost to long-term follow-up. Conclusion: Snake-bite, leading to multiple complications including renal failure and death, is a major health issue in tropical countries. Late referral of these patients to specialized centres Result in undesirable outcome. (author)

    Studies on risk factors of mortality in elderly patients with hemodialysis usually focus on comorbidities, nutrition, and inflammation. Discussion on the correlation between living environment and mortality of these patients is limited. A total of 256 elderly hemodialysis patients participated in this 2-year prospective observational study. The subjects were divided into 2 subgroups based on whether they were living in Taipei Basin (n = 63) or not (n = 193). Demographic, hematological, nutritional, inflammatory, biochemical, and dialysis-related data were obtained for cross-sectional analysis. Causes of death and mortality rates were also analyzed for each subgroup. Patients in the basin group had a higher incidence of combined protein-energy wasting and inflammation than those in the around basin group. At the end of the 2-year follow-up, 68 patients had died. Univariate binary logistic regression analysis revealed that a very advanced age, basin group, serum albumin levels, serum creatinine levels, non-anuria, and the complications of stroke and CAD were associated with 2-year mortality. Meanwhile, log high-sensitivity C-reactive protein (hs-CRP) levels were not associated with 2-year mortality. Multivariate Cox regression analysis revealed that basin group, serum albumin levels, and the complications of stroke and CAD were significant risk factors for 2-year mortality in these patients. The results of this study indicate that factors such as living in the Taipei Basin with higher air pollutant levels in elderly hemodialysis patients is associated with protein-energy wasting and inflammation, as well as 2-year mortality. These findings suggest that among this population, living environment is as important as comorbidities and nutrition. Furthermore, air pollution should be getting more attention especially in the overcrowding Basin topography.

    Acute bilateral renal cortical necrosis (BRCN) has been reported following envenoming by exotic venomous snakes. Proatheris superciliaris is a rare viper with restricted distribution in east Africa. Very little information is available on envenoming by this species. We herein describe the case of a 60-year-old professional wildlife photographer who was bitten on his thumb while photographing an adult specimen of P. superciliaris that he held at home in France. On admission, physical examination revealed severe hypertension and bruising with edema at the bite site. Within the following 24 h, he developed vomiting, diarrhea, acute lumbar pain and anuria. Laboratory tests showed acute kidney injury (serum creatinine 4.6 mg/dL), with thrombocytopenia, anemia and severe coagulopathy. Contrast-enhanced computed tomography scan revealed hypodense areas in the cortex of both kidneys consistent with diffuse BRCN. As no appropriate antivenom existed, only symptomatic care was given to the patient. Coagulation tests returned to normal within 48 h. The patient was placed on chronic hemodialysis, until he underwent successful kidney transplantation 18 months later. In developed countries, severe complications provoked by snake bites tend to be more frequent with the number of trendy exotic pets. Acute kidney injury, including BRCN, is a classic complication of viper bites. The present case of end-stage renal failure related to diffuse BRCN illustrates the potentially devastating effects of envenoming by P. superciliaris. Clinicians in developed countries should be informed about renal disorders and other potentially fatal complications of venomous snake bites and seek urgent expert advice for optimizing clinical management. Education and coaching of envenomed patients and exotic snake owners is mandatory to prevent dramatic accidents. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Acute kidney injury (AKI is one of the most challenging and serious complications of pregnancy. We present our experience on the clinical profile and outcome of 57 patients with pregnancy-related AKI, of a total of 580 patients with AKI seen during the study period. This is a prospective single-center study in a civil hospital conducted from January to December 2010. The most common age group of the study patients was 20-25 years; 43.8% of the patients had received antenatal care. AKI was observed in the puerperium (n = 34, early pregnancy (n = 10 and late pregnancy (n = 13. The cause of AKI included puerperal sepsis (63.1%, pregnancy-induced hypertension (PIH (33.33%, post-abortion (22.80%, ante-partum hemorrhage (APH (14% and post-partum hemorrhage (PPH (8%. Complete, partial and no renal recovery was observed in 52.64%, 21.05% and 26.31% of the patients, respectively. Low platelet count and plasma fibrinogen and high bilirubin, D-dimer and activated partial throm-boplastin time were observed more commonly in patients with partial recovery. Of the 57 patients, 50 received hemodialysis, three received peritoneal dialysis and seven patients were managed conserva-tively. A total of 13 patients developed cortical necrosis that was associated with sepsis in six, PPH and pre-eclampsia/eclampsia in three patients each and APH in one. Nine patients died, and the cause of death was septicemia in four, pre-eclampsia in three and APH and PPH in one patient each. In our study, puerperal sepsis was the most common etiological factor for pregnancy-related AKI. Prolonged oliguria or anuria were bad prognostic factors for renal recovery. Sepsis, thrombocytopenia, disseminated intra-vascular coagulation and liver involvement were associated with increased mortality.

    Transport characteristics of phosphorus are different from other small solutes that are evaluated in routine peritoneal equilibration test (PET) in peritoneal dialysis (PD) patients. We aimed to evaluate peritoneal phosphorus clearance and permeability, and their relationship with peritoneal membrane transport type and creatinine clearance as well as factors affecting peritoneal phosphorus clearance. 70 adult patients on a PD program were included in our study. Phosphorus transport status was classified according to dialysate/plasma (D/P) phosphorus at the 4th hour of PET as slow transporter ( 0.67). We evaluated the relationship of peritoneal phosphorus clearance and transport type with PD regime, phosphorus level, and presence of residual renal function in addition to investigating factors that are effective on peritoneal phosphorus clearance. D/P phosphorus and peritoneal phosphorus clearance were positively correlated with D/P creatinine and peritoneal creatinine clearance, respectively. Automated PD and continuous ambulatory PD patients were similar regarding phosphorus and creatinine clearances and transport status based on D/P phosphorus. The major determinant of peritoneal phosphorus clearance was anuria status. Anuric patients had higher dialysate volume (11.6 ± 3.0 L vs. 8.4 ± 2.1 L, p peritoneal phosphorus clearance (61.7 ± 15.1 L/week/1.73 m2 vs. 48.4 ± 14.0 L/week/1.73 m2, p = 0.001). Hyperphosphatemia was present in 40% and 11% of anuric patients and those with residual renal function, respectively (p = 0.005). Peritoneal phosphorus transport characteristics are similar to that of creatinine. Although increased dialysis dose may increase peritoneal phosphorus clearance, it may be insufficient to prevent hyperphosphatemia in anuric patients.

However, systemic inflammation is one of the possible pathogenesis of UP, and blood lead level (BLL has been noted to be associated with inflammation and nutritional status in long-term HD patients. There might be an interaction or association, therefore, between BLL and UP through systemic inflammation. We analyzed cross-sectional data among 866 participants. All of the 866 patients in this study were stratified into groups with low-normal (<10 µg/dL, high-normal (10–20 µg/dL, and abnormal BLLs (>20 µg/dL. The associations between UP and BLL and the clinical data were analyzed. Multivariate logistic regression demonstrated that HD duration, non-anuria, log ferritin, serum low-density lipoprotein, log BLL, high-normal BLL, and high BLL were associated with UP. In conclusion, BLL was positively associated with UP. Keywords: blood lead levels, uremic pruritus, hemodialysis

    Kidney Diseases contribute a significant proportion to the global burden of non-communicable diseases. Haemodialysis services as the main modality of renal replacement therapy in most resource limited countries is only available in few cities and at higher costs. The aim of this study was to determine the challenges and outcomes of patients who were on haemodialysis at the University of Dodoma (UDOM) haemodialysis unit in Tanzania. In this retrospective study; we reviewed haemodialysis registers and charts of 116 patients dialyzed from January 2013 to June 2015 at The UDOM haemodialysis unit. Data were descriptively and inferentially analysed using Stata version 11 software. Of the 116 patients, 52 (44.9%) were male, and 38(32.8%) were married. Their median age was 45 years. Thirty-two (27.6%) had acute kidney injury, of them 26 (81.3%) patients had recovery of renal function after haemodialysis. Indications for hemodialysis were anuria (18), intoxications (14), electrolyte imbalance (9), uraemia (7) infections (6) and fluid overload (4). Eighty-four (72.4%) patients had End Stage Renal Diseases (ESRD), of which 37 (44.1%) absconded/lost to follow up, 15 (17.9%) died, 22 (26.2%) were referred to Muhimbili National Hospital (MNH), 12 for possible kidney transplant abroad after haemodialysis, and 10 (11.9%) were still attending our unit for haemodialysis. Residing outside Dodoma was predictive for poor outcomes while on haemodialysis (OR 5.2, 95% CI 3.2-8.6, p challenges for better outcomes. Therefore, haemodialysis and renal transplants services should be made easily available in regional referral hospitals at reasonable costs. In addition, members of the public should be educated on joining health insurance schemes and on making healthy life style choices for preventing chronic kidney disease and its progression.

  5. Angiotensin I-converting enzyme Gln1069Arg mutation impairs trafficking to the cell surface resulting in selective denaturation of the C-domain.

    Directory of Open Access Journals (Sweden)

    Sergei M Danilov

    Full Text Available BACKGROUND: Angiotensin-converting enzyme (ACE; Kininase II; CD143 hydrolyzes small peptides such as angiotensin I, bradykinin, substance P, LH-RH and several others and thus plays a key role in blood pressure regulation and vascular remodeling. Complete absence of ACE in humans leads to renal tubular dysgenesis (RTD, a severe disorder of renal tubule development characterized by persistent fetal anuria and perinatal death. METHODOLOGY/PRINCIPAL FINDINGS: Patient with RTD in Lisbon, Portugal, maintained by peritoneal dialysis since birth, was found to have a homozygous substitution of Arg for Glu at position 1069 in the C-terminal domain of ACE (Q1069R resulting in absence of plasma ACE activity; both parents and a brother who are heterozygous carriers of this mutation had exactly half-normal plasma ACE activity compared to healthy individuals. We hypothesized that the Q1069R substitution impaired ACE trafficking to the cell surface and led to accumulation of catalytically inactive ACE in the cell cytoplasm. CHO cells expressing wild-type (WT vs. Q1069R-ACE demonstrated the mutant accumulates intracellularly and also that it is significantly degraded by intracellular proteases. Q1069R-ACE retained catalytic and immunological characteristics of WT-ACE N domain whereas it had 10-20% of the nativity of the WT-ACE C domain. A combination of chemical (sodium butyrate or pharmacological (ACE inhibitor chaperones with proteasome inhibitors (MG 132 or bortezomib significantly restored trafficking of Q1069R-ACE to the cell surface and increased ACE activity in the cell culture media 4-fold. CONCLUSIONS/SIGNIFICANCE: Homozygous Q1069R substitution results in an ACE trafficking and processing defect which can be rescued, at least in cell culture, by a combination of chaperones and proteasome inhibitors. Further studies are required to determine whether similar treatment of individuals with this ACE mutation would provide therapeutic benefits such as

    Pediatric nephrology is challenging in developing countries and data on the burden of kidney disease in children is difficult to estimate due to absence of renal registries. We aimed to describe the epidemiology and outcomes of children with renal failure in Cameroon. We retrospectively reviewed 103 medical records of children from 0 to 17 years with renal failure admitted in the Pediatric ward of the Douala General Hospital from 2004 to 2013. Renal failure referred to either acute kidney injury (AKI) or Stage 3-5 chronic kidney disease (CKD). AKI was defined and graded using either the modified RIFLE criteria or the Pediatrics RIFLE criteria, while CKD was graded using the KDIGO criteria. Outcomes of interest were need and access to dialysis and in-hospital mortality. For patients with AKI renal recovery was evaluated at 3 months. Median age was 84 months (1QR:15-144) with 62.1% males. Frequent clinical symptoms were asthenia, anorexia, 68.8% of participants had anuria. AKI accounted for 84.5% (n = 87) and CKD for 15.5% (n = 16). Chronic glomerulonephritis (9/16) and urologic malformations (7/16) were the causes of CKD and 81.3% were at stage 5. In the AKI subgroup, 86.2% were in stage F, with acute tubular necrosis (n = 50) and pre-renal AKI (n = 31) being the most frequent mechanisms. Sepsis, severe malaria, hypovolemia and herbal concoction were the main etiologies. Eight of 14 (57%) patients with CKD, and 27 of 40 (67.5%) with AKI who required dialysis, accessed it. In-hospital mortality was 50.7% for AKI and 50% for CKD. Of the 25 patients in the AKI group with available data at 3 months, renal recovery was complete in 22, partial in one and 2 were dialysis dependent. Factors associated to mortality were young age (p = 0.001), presence of a coma (p = 0.021), use of herbal concoction (p = 0.024) and acute pulmonary edema (p = 0.011). Renal failure is severe and carries a high mortality in hospitalized children in Cameroon

    Background Available data on the characteristics of patients with Ebola virus disease (EVD) and clinical management of EVD in settings outside West Africa, as well as the complications observed in those patients, are limited. Methods We reviewed available clinical, laboratory, and virologic data from all patients with laboratory-confirmed Ebola virus infection who received care in U.S. and European hospitals from August 2014 through December 2015. Results A total of 27 patients (median age, 36 years [range, 25 to 75]) with EVD received care; 19 patients (70%) were male, 9 of 26 patients (35%) had coexisting conditions, and 22 (81%) were health care personnel. Of the 27 patients, 24 (89%) were medically evacuated from West Africa or were exposed to and infected with Ebola virus in West Africa and had onset of illness and laboratory confirmation of Ebola virus infection in Europe or the United States, and 3 (11%) acquired EVD in the United States or Europe. At the onset of illness, the most common signs and symptoms were fatigue (20 patients [80%]) and fever or feverishness (17 patients [68%]). During the clinical course, the predominant findings included diarrhea, hypoalbuminemia, hyponatremia, hypokalemia, hypocalcemia, and hypomagnesemia; 14 patients (52%) had hypoxemia, and 9 (33%) had oliguria, of whom 5 had anuria. Aminotransferase levels peaked at a median of 9 days after the onset of illness. Nearly all the patients received intravenous fluids and electrolyte supplementation; 9 (33%) received noninvasive or invasive mechanical ventilation; 5 (19%) received continuous renal-replacement therapy; 22 (81%) received empirical antibiotics; and 23 (85%) received investigational therapies (19 [70%] received at least two experimental interventions). Ebola viral RNA levels in blood peaked at a median of 7 days after the onset of illness, and the median time from the onset of symptoms to clearance of viremia was 17.5 days.

    To describe lower urinary tract symptoms (LUTS) and their management in renal transplant candidates and recipients. Relevant publications were identified through Medline (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) database using the following keywords, alone or in association: "transplantation", "prostate hyperplasia", "transurethral resection of prostate", "urinary incontinence", "LUTS", "pelvic floor dysfunction". Articles were selected according to methods, language of publication and relevance. The reference lists were used to identify additional historical studies of interest. Both prospective and retrospective series, in French and English, as well as review articles and case reports were selected. In addition, French national transplant and health agencies (http://www.agence-biomedecine.fr and http://www.has-sante.fr) databases were screened using identical keywords. A total of 991 articles were analyzed and after careful selection, 47 publications were eligible for our review. Reduction of bladder capacity, due to dialysis and anuria, is correlated with dialysis duration. This reduction is reversible after renal transplantation and does not seem to put renal transplant recipients at risk for medical complications. Transplant procedure generally allows restoration of bladder maximal output, normal bladder capacity and compliance. Medical treatment of LUTS related to prostate hyperplasia (BPH) includes alpha-blockers and finasteride. Silodosin and dutasteride have not been evaluated in that setting. Antimuscarinics may be used with caution, and favor the use of solifenacin at 5mg per day. Surgical treatment of BPH requires a preserved urine output, otherwise must be delayed after transplantation; it may thus be performed safely in the early postoperative course. Botulinum toxin injections and surgical treatment of stress incontinence and prolapse are barely reported in this population. Precise assessment and optimal management of LUTS in

Urinalysis findings were proteinuria, glucosuria, hematuria, cilindruria, celluria and decrease of urinary specific gravity and crescent values of urinary gamma glutamyl transpeptidase from 24 hours after gentamicin administration until the "end of" the experiment. Azotemia was noticed on the 12th and 14th days of the study. Acute tubular nephrosis was established in the histological evaluation. Based on the results found on this study, the measurement of the urinary gamma glutamyl transpeptidase activity might be considered a sensitive indicator of renal tubular damage allowing early diagnosis of the lesion.

    To investigate the relationship between obesity, small-solute clearances, and nutrition in continuous peritoneal dialysis (CPD), we compared clearances and nutrition indices between 270 obese and 502 normal-weight CPD patients. Degree of obesity was classified by the ratio of body weight (W) to desired weight (DW) at the first clearance study. The DWs were obtained from the tables of the Metropolitan Life Insurance Company, assuming a medium skeletal frame. The obese patients (group I) had W/DW > 1.2 (1.38 +/- 0.17), and the normal-weight patients (group II) had 0.9 W/DW W and DW. The following variables differed between group I (first value) and group II: sex (women: 48.2% vs. 33.9%), W (87.6 +/- 14.4 kg vs. 68.2 +/- 8.7 kg), body surface area (1.95 +/- 0.22 m2 vs. 1.77 +/- 0.16 m2), body water by method of Watson (41.2 +/- 7.7 L vs. 36.3 +/- 5.5 L), body mass index (31.8 +/- 3.9 vs 24.3 +/- 2.0), protein nitrogen appearance (PNA: 62.9 +/- 17.6 kg in 24 h vs. 57.7 +/- 15.7 kg in 24 h), PNA normalized to DW (1.08 +/- 0.29 g/kg in 24 h vs. 0.96 +/- 0.26 g/kg in 24 h), creatinine excretion (CrEx: 1111 +/- 396 mg in 24 h vs. 991 +/- 348 mg in 24 h), CrEx/W (12.6 +/- 3.7 g/kg in 24 h vs. 15.4 +/- 4.5 g/kg in 24 h), CrEx/DW (17.3 +/- 5.3 g/kg in 24 h vs. 15.1 +/- 4.8 g/kg in 24 h), lean body mass (LBM: 49.3 +/- 13.8 kg vs. 43.6 +/- 11.9 kg), LBM/W (0.56 +/- 0.12 vs. 0.64 +/- 0.15), and LBM/DW (0.77 +/- 0.18 vs 0.67 +/- 0.16), all at p p > 0.05) were found in the diabetes prevalence (53.0% vs. 40.8%), height (165.9 +/- 11.7 cm vs. 167.4 +/- 9.8 cm), and serum albumin (3.64 +/- 0.55 g/dL vs. 3.53 +/- 0.62 g/dL). No differences were found in age, duration of CPD until the first clearance study, percent of subjects with anuria, Kt/V urea, creatinine clearance, blood urea nitrogen, serum creatinine, and PNA normalized to W. Obese CPD patients tend to have better nutrition indices than do normal-weight CPD patients with similar small-solute clearances. In obese subjects

    The study was devised to understand the contribution to nephrology ofDe Medicina Methodicaof Prospero Alpini published in 1511, at a time when the fame of the professor reached the azimuth. We have analyzed the contents of chapters devoted to nephrology in that book of Prospero Alpini and the novelties of his message. Prospero Alpini (1563-1616) taught at the University of Padua (1594-1616), at the same time of Galileo Galilei, Santorio Santorio, and Girolamo Fabrizi dAcquapendente, when measurements (pulse, temperature, perspiration) were introduced into medicine. He was a travelling physician to whom we owe fundamental contributions to the use of urine to prognosticate life and death (De Praesagienda vita et morte aegrotantium libri septem, Venetiis, apud Haeredes Melchioris Sessae,1601). As prefect of the Botanical Garden - the first ever and a model in the world - he could turn the study of simples into cures(De Medicina Methodica Libri Tredecim. Patavi, apud Franciscum Bolzettam, 1611. Ex typographia Laurentij Pasquali, is anin foliovolume of XLVII + 424 pages, 54 lines per page), wherein Alpini aimed to rejuvenate antique medical Methodism. It is a testimony of the interest of medicine philosophers of the modern era for the corpuscular and atomic ideas (Nancy Siraisi). Methodists (2ndCentury BC) refused anatomy and physiology as unique guidelines to the interpretations of diseases and gave importance to the development of a pharmacological science and alternative medicine. The book begins with a 3 page letter to Francis Maria della Rovere Duke of Montefeltro, and a 2 page letter to the readers. We discuss the novelties of the chapters on renal colic (de dolorerenum), hematuria (de sanguinis profluvium), pyuria, anuria (de urina suppressa) and its cure, polyuria (de urina profluvio), renal abscesses, hydrops and its treatment by skin incisions. We also analyze the chapter on kidney and bladder stones (Book X, Chapter XVIII, pp. 354-356) - a masterpiece of

    modificações do metabolismo se traduziram por alterações urinarias e sanguineas. As urinas foram emitidas em muito pequena quantidade (50 cc. em 24 horas não havendo comtudo, anuria absoluta. Cylindros hyalinos e granulosos, bem como leucocytos e cellulas renaes, associadas á albuminoria, era presentes. Os exames chimicos do sangue, revelaram: Proteinas totaes 7,61 grs. em 1000 cc.; Albumina 2,39 grs em 1000 cc.; Globulina 5,22 grs. em 1000 cc.; Uréa 6,42 grs. em 1000 cc.; Fibrinogeneo 0,324 grs. em 1000 cc.; Indican +++; Cl. plasmatico 339 mgrs. em 100 cc.; Cl. globular 170 mgrs. em 100 cc.; Cholesterol 163 mgrs. em 100 cc.; Creatinia 260 mgrs. em 100 cc.; Ph. inorganico 13,4 mgrs. em 100 cc.; Calcio 10,3 mgrs em 100 cc.; Potassio 28 mgrs. em 100 cc.; Sodio 328 mgrs. em 100 cc.. O exame hematologico revelou 11% de hemoglobina; 960.000 hematias por mm.³; e 5.200 leucocytos por mm.³. A formula leucocytaria revelou augmento dos neutrophilos, com 74% dos segmentados. A proporção entre sôro o coagulo foi 9 x 3 cc. A reacção de Wassermann no sôro sanguineo foi negativa. A insufficiencia renal se traduziu no caso em estudo, por modificações humoraes, particularmente pela azotemia elevada, pelo augmento da creatinina, do phosphoro inorganico e do indican. Em contraste com a existencia de taes modificações, o doente não apresentou os signaes clinicos observados nos casos emque a azotemia se mantem elevada, reproduzindo tal facto, o quadro clinico descripto para a necrose symmetrica da cortex renal.In a mortal case of ophidism, in an individual 15 years old, bitten by a snake (Bothrops jararaca on the external face of his right leg and who died 26 days after the accident, the AA. describe the pathologic-anatomical changes met with and the modifications of the metabolism put into evidence through chemical blood examinations.
