    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.

    A 12-year-old male patient suffered hematuria. Histopathology of a biopsy showed granulomata suspicious for schistosomiasis. The patient had never travelled outside Europe during his entire lifetime. He had taken frequent bathes in various rivers during his last family holidays 5 months earlier in Corsica. Microfiltration of urine revealed viable ova of Schistosoma haematobium with alterated size and shape. Ultrasonography showed a large focal echopoor mass attached to the bladder roof. Four days after antihelminthic therapy, the patient suffered inferior abdominal pain and acute anuria. Ultrasound revealed an approximately 5-cm mass in the bladder lumen suspicious for a large blood clot. After taking non-invasive measures such as drinking high amounts of fluid and treating the lower abdomen with a warm water bag and massage, the clot was excreted with urine and symptoms subsided. The further course was uneventful until 11 months later when hematuria recurred. This time, parasitological urine examination confirmed non-viable schistosome ova. Hematuria was likely due to erosion of the bladder mucosa by calcified non-viable ova. PMID:26852123

    Full Text Available BACKGROUND : Urolithiasis in infancy is rare but important health issue. Etiology is multi factorial . Optimal management of pediatric stone disease is still evolving . Infants with bilateral obstructive renal stones are unique group of patients in whom prompt evaluation and management is necessary. AI MS AND OBJECTIVE: To evaluate safety and efficacy of PCNL in infants presenting with bilateral obstructive renal calculi and anuria . MATERIALS AND METHOD S: From N ov . 2012 to M arch 2014, 18 renal units with calculi in 9 infants (6 boys, 3 girls were treated with PCNL ( P ercutaneous N ephrolithotomy at our institution. All infants presented with anuria, rised serum creatinin (mean 6.1mg/dl and uremic symptoms due to bilateral obstructive renal calculi. All patients managed initially with peritoneal dialysis a t nephrology u nit, followed by bilateral DJ (D ouble J stenting, then bilateral PCNL performed in two sittings. Mean age 8.5 months (4m to 12m, mean stone burden 1.7 cm (0.6cm to 3.0 cm, 20 F pediatric nephroscope through 22F percutaneous access was used . Stones were fragmented with pneumatic lithotripter. RESULTS: Mean operative time was 60.22 mins (30 mins to 90 mins. Complete stone clearance was done in all cases without need for second look PCNL. Mean post op serum creatinin is 0.6 mg/dl. No patient r equired blood transfusion, developed urosepsis, or had a procedure related complications. CONCLUSION: When performed by experienced urologists, PCNL is safe and effective procedure in infants presenting with bilateral obstructive renal calculi and anuria, provided these patients managed preoperatively with peritoneal dialysis and DJ stenting to optimise renal function and to relieve sepsis.

  5. Successful Management of Repetitive Urinary Obstruction and Anuria Caused by Double J Stent Calculi Formation after Renal Transplantation

    Full Text Available This report firstly describes an extremely rare case of repetitive double J stent calculi formation after renal transplantation caused by the antihyperparathyroidism (HPT drug calcitriol. In 2012, a woman initially presented to our hospital for anuria with lower abdominal pain. She was diagnosed with allograft hydronephrosis and double J stents obstruction by calculi formation after transplantation and treated with triplicate stents replacements in another hospital without clinical manifestations improvements. Through detailed exploration of medical history, we conclude that the abnormal calculi formation is due to the calcitriol (1,25-dihydroxyvitamin D3 administration, a drug which can increase renal tubular reabsorption of calcium for treating posttransplant HPT bone disease. After discontinuing calcitriol, the patient was stone-free and had a good recovery without severe complications during the 9-month follow-up. Our novel findings may provide an important clue and approach to managing formidable repetitive double J stent calculi formation in the clinical trial.

    2003-03-01

    To evaluate the clinical benefit of the prophylactic use of urate oxidase in children with non-Hodgkin's lymphoma (NHL), we analyzed the incidence and complications of tumor lysis syndrome (TLS) in children with B-cell acute lymphoblastic leukemia (B-ALL) or stage III/IV Burkitt's lymphoma and a lactate dehydrogenase (LDH) level > or =500 U/l before and after the introduction of a protocol amendment to use urate oxidase for the prophylaxis of TLS. Data from 1791 children with NHL enrolled in the two subsequent multicenter studies NHL-BFM 90 and 95 were evaluated. The presence of the side effects TLS, anuria, sepsis, and other complications during the first 2 weeks after admission were registered. Until March 1996, no urate oxidase was used (period 1). From November 1997 all children with B-ALL or stage III and IV B-NHL and LDH > or =500 U/l should receive urate oxidase prophylactically (period 3). In between (period 2), urate oxidase was given in a minority of hospitals therapeutically. Initial chemotherapy was identical. Altogether, 78 children (4.4%) developed a TLS. Patients with B-ALL had the highest risk to develop a TLS (26.4%) followed by B-ALL/Burkitt's lymphoma and a LDH > or =500 U/l (14.9%). In period 1, 16.1% and 9.2% of the latter children developed a TLS or anuria, respectively, compared to 12.3% and 6.2% in period 3 ( p=NS). The incidence of sepsis remained unchanged (5.0% vs 4.6%). In children with B-ALL the differences in the incidence of TLS and anuria between period 3 and period 1 were more pronounced, reaching significance for anuria (15.4% vs 3.8%, p=0.03). Our results suggest that patients with the highest risk to develop a TLS might benefit from the prophylactic use of urate oxidase. PMID:12634948

    1978-08-01

    A 39-year-old man had anuria and azotemia and was found to be suffering from acute arsenic poisoning. After two peritoneal dialyses, partial renal function returned, and the patient has survived for five years without dialysis. Renal cortical necrosis was demonstrated by renal biopsy and renal calcification. We suggest that arsenic be added to the list of substances capable of causing renal cortical necrosis and recommend consideration of this complication in cases of arsenical poisoning.

  13. Aortic Dissection and Renal Failure in a Patient with Severe Hypothyroidism

    Directory of Open Access Journals (Sweden)

    2012-01-01

    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.

    2009-08-01

    Full Text Available Uraemic toxemia is a condition resulting due to the retention of toxic waste metabolite of urine like urea, creatinine etc. in the blood. Which may prove fatal many a times. The retention of urine may be a sequelee of severe dehydration leading to oliguria followed by anuria or due to the nephritis in a animals. It has been observed that nephritis is oftenly associated with pyometra also. In the present study the elevated levels of urea and creatinine were alarmingly elevated and was life threatening also. However the timely diagnosis & surgical intervention could save and prolong the life of bitch. [Vet. World 2009; 2(4.000: 146-147

    Schou-Jensen, Katrine; Mohammad, Wael

    2015-01-26

    In Denmark, kidney transplantations in patients above 50 years have increased during the last decade. Consequently, the number of patients with lower urinary tract symptoms due to prostate hypertrophy increases accordingly. We describe two patients, who both had a resection of the prostate while having anuria and waiting for a kidney transplantation from a deceased donor. In both cases it was impossible to place a urethral catheter during the following transplantation due to total urethral occlusion, so a suprapubic catheter was inserted until the scar tissue was dilated or resected by a later transurethral intervention.

    2014-11-01

    Bilateral renal vein thrombosis is an unusual etiology of acute renal failure and usually is associated with nephrotic syndrome. We report a 77-year-old man, consulting in the emergency room for anuria that appeared 24 hours after a syncope. The patient was carrier of an inferior vena cava filter prophylactically installed 17 months earlier and was not receiving anticoagulation. Serum creatinine on admission was 5.45 mg/dl and blood urea nitrogen was 54 mg/dl. Computed tomography and Doppler ultrasonography showed an extensive thrombosis of inferior vena cava and both renal veins. Heparin therapy was started with a rapid recovery of renal function and diuresis.

    In this case report, we describe our experience of managing a patient with chemical burns caused by hot chromic acid that covered over 60% of the patient's body. The patient developed anuria 48 hours after injury. Early excision of burn eschars and hemodialysis were carried out. The patient survived after a series of comprehensive treatments, including allografting and autografting. In patients burned by hot chromic acid, excision of affected skin down to the muscle fascia should be carried out as soon as possible after injury. Dialysis to remove circulating chromium in the first 24 hours after injury is also recommended.

  18. Severe loin pain following renal biopsy in a high-risk patient: A case report of a rare combination of pseudoaneurysm and arterio-venous fistula

    Desai Madhav

    2011-01-01

    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.

  19. The cause of P.I. Tchaikovsky's (1840-1893) death: cholera, suicide, or both?

    2010-01-01

    The death of P. I. Tchaikovsky (1840 - 1893) excites imagination even today. According to the "official scenario", Tchaikovsky had suffered from abdominal colic before being infected with cholera. On 2 November 1893, he drank a glass of unboiled water. A few hours later, he had diarrhoea and started vomiting. The following day anuria occured. He lost consciousness and died on 6 November (or on 25 Oktober according to the Russian Julian calendar). Soon after composer's death, rumors of forced suicide began to circulate. Based on the opinion of the musicologist Alexandra Orlova, the main reason for the composer's tragic fate lies in his homosexual inclination. The author of this article, after examining various sources and arguments, concludes that P. I. Tchaikovsky died of cholera.

    The aim of our report is to increase awareness that the antioxidant alpha-lipoic acid, which is marketed primarily as weight loss and energy supplement, has potentially lethal effects. A 14-year-old girl ingested in suicidal intention a large amount of alpha-lipoic acid, which led to multiorgan failure and subsequent death within 24 h. Multiorgan failure consisted of decreased myocardial contractility, seizures, anuria, thrombocytopenia, and coagulopathy. Therapy consisted of ventilation, anticonvulsive treatment and circulatory support with high-dose catecholamines. According to alpha-lipoic acid serum levels following ingestion the girl must have ingested a minimum of 10 alpha-lipoic acid tablets of 600 mg each. This is the first report on a fatal case of alpha-lipoic acid ingestion, which is intended to inform physicians, pharmacists and patients about critical side effects of this allegedly innocuous drug.

    CASE DESCRIPTION A 6-year-old neutered male domestic shorthair cat was evaluated because of signs of abdominal pain and anuria of 12 hours' duration after vehicular trauma. CLINICAL FINDINGS Lethargy, mydriasis, bradycardia, abdominal distension, and signs of pain on abdominal palpation were observed. Abdominal ultrasonography revealed moderate urinary bladder distension without evidence of free abdominal fluid; hematologic evaluation revealed leukocytosis with high BUN and serum creatinine concentrations. TREATMENT AND OUTCOME The patient was hospitalized, medical stabilization was attempted, and an indwelling urinary catheter was placed. Urinary output was cat was free of clinical signs, and results of ultrasonography, CBC, and serum biochemical analysis were unremarkable. CLINICAL RELEVANCE Results suggested that a Boari flap procedure with renal descensus could be a feasible alternative in the management of proximal ureteral rupture in cats, but research is needed in this area.

    2011-01-01

    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.

    2003-06-01

    A 38-year-old woman with end stage renal disease received a living related donor-renal transplant to the right iliac fossa. She developed anuria a week later. Tc-99m MAG{sub 3} renal scintigraphy demonstrated no perfusion, uptake, or excretion of the radioactive tracer from the renal transplant. The expected area of the renal allograft appeared as a photopenic area with increased rim activity. The gallbladder and bowel activities were observed on delayed images at 24 hours. There was no blood flow within the renal artery on renal doppler examination. This case shows total absence of perfusion and function in the infarcted renal transplant with extrarenal excretion of Tc-99m MAG{sub 3} caused by acute renal artery thrombosis.

  4. Cystic uterus masculinus in the dog: six case history reports

    International Nuclear Information System (INIS)

    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

    Spontaneous renal vein thrombosis (RVT) is very rare in the absence of nephrotic syndrome. It is more common in newborns and infants. RVT should always be included in the differential diagnosis of flank pain and hematuria, and because RVT can induce acute renal injury. A 19-year-old man was admitted to our hospital because he complained of right flank pain and oliguria for 3 days. Another patient, a 24-year-old man, complained of a severe and sudden onset of bilateral flank pain and anuria for a day. They were both healthy before they developed the described symptoms and had different levels of decrease in renal function when they visited the hospital. Color Doppler ultrasonography revealed RVT in both the patients. The patients received therapy, including anticoagulation and thrombolysis, following their diagnoses, and they recovered in a few days.

    Neonatal renal vein thrombosis (NRVT) is a rare thromboembolic complication in the neonatal period, and sequelae from renal dysfunction can cause significant morbidity. The authors retrospectively reviewed 10 patients with NRVT treated at their institution. The majority of the cohort were male (n = 9), preterm (n = 6), and had unilateral NRVT (n = 6). Six patients received thrombolysis and/or anticoagulation, and 4 patients received supportive care only. Two of the 6 patients treated with anticoagulation who had bilateral NRVT and anuria received thrombolysis with low-dose tissue plasminogen activator. Thrombolysis was not associated with any major adverse events, and both patients had marked improvement of renal function. Eight patients subsequently developed renal atrophy (3 received anticoagulation, 2 received thrombolysis with anticoagulation, and 3 received supportive care). Anticoagulation/thrombolysis did not appear to prevent renal atrophy. The role of thrombolysis needs to be further studied and considered in the setting of bilateral NRVT and acute renal failure.

    We report the case of a 66-year-old woman with no significant past medical history who presented to the Emergency Department at Houston Methodist Hospital with 24 hours of chest pain. An electrocardiogram was done, an electrocardiogram confirmed a posterolateral ST elevation myocardial infarction. An immediate and successful percutaneous coronary intervention of a totally occluded ramus intermedius was performed. Six hours later she developed pulmonary edema, cardiogenic shock, severe acidosis, and anuria. Echocardiography showed severe mitral regurgitation due to a ruptured anterolateral papillary muscle, and emergency surgery revealed necrosis of this muscle. A bioprosthetic mitral valve was placed, and extracorporeal membrane oxygenation was needed for 3 days. This is a rare mechanical complication of myocardial infarction, which usually affects the posteromedial papillary muscle. The patient subsequently made a good recovery. One month later, just prior to discharge home, the patient developed pneumonia and sepsis, and she expired from multiorgan failure. PMID:25793030

    2011-01-01

    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.

    Full Text Available Background: Malaria has protean clinical manifestations and acute kidney injury (AKI is one of its serious and life threatening complications. This study was carried out to describe the clinical characteristics, and factors associated with adverse outcomes, in patients with malarial AKI. Materials and Methods: Data of 100 patients with AKI and smear positive malaria was retrospectively analyzed to evaluate the incidence, clinical profile, outcome and predictors of mortality among all cases presented to us at the Nephrology unit of Jawaharlal Nehru Medical College, Aligarh Muslim University, Aligarh between November 2010 to October 2011. Results were expressed as mean, standard deviation (SD and range. Results: One hundred (22.1% (68 males, 32 females cases of malaria induced AKI, amongst 452 total cases of AKI, were evaluated. The mean age (± SD was 30 ± 11.23 years. Male to female ratio was 3.3:1. Plasmodium falciparum was reported in 76%, P. vivax in 11%, and both in 13% patients. The mean serum creatinine was 8.7 ± 3.7 mg%, and oligo/anuria was present in 84% of the patients. 78% of the patients required hemodialysis. 67% of the patients recovered completely, 12% did not show full recovery, and 6% developed chronic kidney failure. Mortality occurred in 15% of the patients. Conclusion : Malarial AKI most commonly occurs in patients infected by Plasmodium Falciparum. Falciparum malaria associated with AKI is a life threatening condition. Prolonged disease duration, low hemoglobin, oligo/anuria on admission, hyperbilirubinemia, cerebral malaria, disseminated intravascular coagulation, and high serum creatinine were the main predictors of mortality in our study.

    Full Text Available Sugarcane (Saccharum officinarum Linn. is an important perennial grass of Poaceae family, indigenous to tropical South Asia and Southeast Asia. It is cultivated worldwide due to the economical and medicinal value of its high yielding products. Sugarcane juice is well known as a raw material for the production of refined sugar and its wax is considered as a potential substitute for the expensive carnauba wax, which is of cosmetic and pharmaceutical interest. Refined sugar is the primary product of sugarcane juice, but during its processing, various other valuable products are also obtained in an unrefined form, such as, brown sugar, molasses, and jaggery. Sugarcane juice is widely used in India in the treatment of jaundice, hemorrhage, dysuria, anuria, and other urinary diseases. Herein, we have summarized the different phytoconstituents and health benefits of sugarcane and its valuable products. The phytochemistry of sugarcane wax (obtained from the leaves and stalks of sugarcane, leaves, juice, and its products has revealed the presence of various fatty acid, alcohol, phytosterols, higher terpenoids, flavonoids, -O- and -C-glycosides, and phenolic acids. The future prospective of some of the sugarcane products has been discussed, which needs a phytopharmacological study and has a great potential to be a valuable medicinal product.

  13. Fibroproliferative response to urothelial failure obliterates the ureter lumen in a mouse model of prenatal congenital obstructive nephropathy.

    Congenital obstructive nephropathy (CON) is the most prevalent cause of pediatric chronic kidney disease and end-stage renal disease. The ureteropelvic junction (UPJ) region, where the renal pelvis transitions to the ureter, is the most commonly obstructed site in CON. The underlying causes of congenital UPJ obstructions remain poorly understood, especially when they occur in utero, in part due to the lack of genetic animal models. We previously showed that conditional inactivation of Sec10, a central subunit of the exocyst complex, in the epithelial cells of the ureter and renal collecting system resulted in late gestational bilateral UPJ obstructions with neonatal anuria and death. In this study, we show that without Sec10, the urothelial progenitor cells that line the ureter fail to differentiate into superficial cells, which are responsible for producing uroplakin plaques on the luminal surface. These Sec10-knockout urothelial cells undergo cell death by E17.5 and the urothelial barrier becomes leaky to luminal fluid. Also at E17.5, we measured increased expression of TGFβ1 and genes associated with myofibroblast activation, with evidence of stromal remodeling. Our findings support the model that a defective urothelial barrier allows urine to induce a fibrotic wound healing mechanism, which may contribute to human prenatal UPJ obstructions. PMID:27511831

    Full Text Available In the diffuse medical diseases of kidney, percutaneous renal biopsy is a valuable, safe and hazardless procedure. With the aid of this nearly new technique renal pathology, the natural history of renal diseases and the response of renal diseases to therapy, as well as the prognosis of renal disorders can be evaluated."nWe have analysed 210 percutaneous biopsies in Tehran. Complications were observed in 13% of cases, there is no mortality and no patient required drastic therapeutic intervention. Anuria, peri-renal colic and peri-renal hematoma were the only serious complications, which were seen in 4 patients, and were. readily controled with simple measures We obtained renal tissue in 95% cases of our patients and in 9 I% of them the tissue was adequate for c'ear diagnosis."nLike other authors, we believe that the procedure, when properly performed, can give a far more valuable informations about the patients without any realy dangerous risk.

  15. New aspects for nuclear renal diagnosis

    International Nuclear Information System (INIS)

    Non-invasive nuclear methods of examination have gained great importance in renal diagnosis because they can be carried out without discomfort to the patient. Unilateral clearance is valuable in cases of unilateral renal damage where the impaired functioning of one kidney may be mashed by the compensatory action of the other, contralateral kidney. This is offen the case with chronic pyelonephritis, ureteral stenosis, and nephrolithiasis. In ectactic renal pelves, unilateral clearance should be obligatory, as functional assessment on the basis of the excretory urogram is impossible. The pathological X-ray picture often leads to false conclusions in this type of disease. Due to the low radiation exposure involved, close-meshed control examinations are possible which indicate functional changes early enough for the necessary therapy. The emphasis in scintiscanning has shifted to dynamic investigations. The main fields of application for sequential scintiscanning are unilateral and segmental renal diseases, differential diagnosis of anuria, traumatic changes, and emergency diagnoses in infants. Suspected growing and displacing processes are only an indirect indication for scintiscanning today. (orig.)

    Results: Two comparable groups of PCN and DJS were formed with a mean age of 45.5 years and 47.9 years. Male to female ratio was 1.5:1 and 1.2:1 respectively. Pain with oliguria or anuria was the major presentation. The urine output levels showed a sudden increase postoperatively with a subsequent trend towards normal value in both the groups. Creatinine however showed a normalizing trend from a mean 6.46 mg/dl preoperatively to 1.01mg/dl postoperatively in PCN group whereas in DJS group 5.38mg/dl preoperatively to 2.75mg/dl with a rising trend from POD 15 requiring conversion to PCN in 20% of patients with subsequent normalization of creatinine levels to 0.95 mg/dl. Statistically we found no difference in the outcome when both the groups were compared in view of serum creatinine and urine output levels whereas there is a significant difference in the pre and post operative outcome of both the groups. Conclusions: Our results thus support that though there is no significant difference among both the procedures, ureteral stents are associated with intolerable lower urinary tract symptoms owing to conversion to secondary percutaneous Nephrostomy. Hence percutaneous nephrostomy is superior to ureteral stents for diversion of urine in patients with ARF due to obstructive uropathy. [Int J Res Med Sci 2016; 4(8.000: 3486-3491

    White, R N

    2001-10-01

    Urethropexy was performed on 100 bitches for the management of urethral sphincter mechanism incompetence (SMI). The dogs ranged in age from 12 months to nine years (mean 4.5 years). Diagnosis of the condition was based upon clinical, laboratory and contrast radiographic examinations, and clinical response to medical management. In all bitches, incontinence developed in the adult individual and in the majority (89 bitches) after spaying. Radiographic findings were unremarkable in 22 bitches, apart from the presence of an intrapelvic bladder neck. Follow-up periods ranged from 12 months to seven years (mean 2.9 years). Fifty-six bitches were completely cured by surgery, 27 became less incontinent and 17 either failed to respond (nine animals) or showed an initial improvement in urinary function, but then relapsed (eight animals). Nine of these 17 animals underwent a second urethropexy procedure, resulting in a cure in six and an improvement in three cases (follow-up 12 to 41 months, mean 22.2 months). A deterioration in the response rate was observed over time. Postoperative complications were seen in 21 bitches and included an increased frequency of micturition (14 bitches), dysuria (six bitches) and anuria (three bitches). PMID:11688522

    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.

    Recent advances in neonatal cardiorespiratory management and neonatal renal replacement therapy have led to occasional reports of favorable short-term and long-term outcomes for Potter sequence, once thought to be fatal. The present patient was a girl born at a gestational age of 34 weeks 4 days with a birthweight of 1398 g. She was diagnosed with Potter sequence complicated by pulmonary hypoplasia due to left renal agenesis and small right kidney. Hemodialysis was started because anuria persisted even after persistent pulmonary hypertension receded and cardiorespiratory status improved. Peritoneal dialysis during the clinical course failed to achieve stability because of pericatheter leakage and frequent obstruction of the peritoneal dialysis catheter; in the meantime, hemodialysis was also performed. Once bodyweight passed 3.5 kg, peritoneal dialysis became more feasible with stability; the patient was discharged at 9 months and at the time of writing was on peritoneal dialysis at home, and renal transplantation was planned.

    Full Text Available Aim: The aim of this study was to evaluate the simple tube cystostomy procedure for management of urethral obstruction cases in ruminants. Materials and Methods: Tube cystostomy was used to treat a total of 58 ruminants, which included 35 buffalo calves and 23 goats. Diagnosis of the disease was made with the history of anuria, clinical signs, and physical examinations. Physical parameters like heart rate, respiratory rate, rectal temperature dehydration status of animals by skin tenting test, and intraoperative findings were compared. Results: Young ruminants were most commonly affected and the mean age was 4-5 months in both species. Only male were considered for the study in which buffalo calves were not castrated but in goat's 73.91% animal were castrated and 34.7% not castrated. Rupture of bladder was more common in buffalo calves as compared to goats. The confirmed cases of obstructive urolithiasis were selected for tube cystostomy with Foley's catheter. Postoperatively all cases were administered with broad spectrum antibiotic, anti-inflammatory agent, and caliculolytic agents like ammonium chloride. Postoperative complications recorded only in 10 animals and remaining 48 animals had an uneventful recovery. Conclusion: Tube cystostomy is a simple and effective procedure particularly in intact urinary bladder, which can be adopted at field level.

    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%.

    Full Text Available Melandrii Herba (MH is a traditional Asian medicinal herb used to treat breast cancer, anuria, and diseases of lactation. However, its biological properties and molecular mechanisms have not been fully elucidated. The purpose of this study was to investigate the anti-inflammatory activity and underlying molecular mechanism of MH ethanol extract (MHE on the lipopolysaccharide (LPS-mediated inflammatory response in macrophages. MHE cytotoxicity was determined using a cell counting kit (CCK assay. The effects of MHE on the production of NO, inflammatory cytokines, and related proteins and mRNAs were determined using the Griess test, ELISA, Western blotting, and real-time RT-PCR, respectively. In addition, intracellular signaling pathways, such as NF-κB, MAPK, and HO-1, were analyzed using Western blotting. Our results revealed that MHE treatment significantly inhibited the secretion of NO and inflammatory cytokines, including TNF-α, IL-6, and IL-1β in macrophages, at sub-cytotoxic concentrations. Furthermore, MHE treatment inhibited iNOS expression and induced HO-1 expression. Finally, the transcriptional activities of NF-κB and MAPK activation were significantly suppressed by MHE in LPS-stimulated macrophages. The results indicate that MHE exerts anti-inflammatory effects by suppressing inflammatory mediator production via NF-κB and MAPK signaling pathways inhibition and induction of HO-1 expression in macrophages. Therefore, our results suggest the potential value of MHE as an inflammatory therapeutic agent developed from a natural substance.

    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.

    2002-01-01

    Full Text Available Pulmonary thromboembolism is a clinical and pathophysiological condition caused by occlusion of pulmonary arteries by thrombotic embolus. Deep venous thrombosis needn't necessarily be evident. Acute renal insufficiency is a syndrome manifested by rapid decrease or even complete urinary retention which may be due to obturation of renal arteries by a thrombus. The condition is clinically manifested by hematuria, oliguria, anuria and death due to uremia. Case Report The patient had a history of disease and a chest X-ray finding both irrelevant for establishing the working diagnosis. Blood gas analysis presented prominent hypoxemia with hyperventilation and ECG finding exhibited right heart overload, pointing to pulmonary thromboembolism. On the third day of treatment with heparin, the patient developed hematuria, oliguria and excessive elevation of nitrogen in blood as a sign of acute renal insufficiency, leading to fatal outcome. Autopsy revealed deep venous thrombosis of the left femoral vein, with massive pulmonary thromboembolism and thrombosis of both femoral arteries, inducing acute renal failure. Discussion Although the patient had a typical radiologic presentation of pulmonary thromboembolism, treatment with heparin was initiated on the basis of his blood gas analysis and ECG findings. Deep venous thrombosis was not clinically evident and acute renal failure could not be explained during patient's lifetime. Conclusion This is a rare case of acute renal failure due to a rare occurrence of bilateral acute thrombosis of renal arteries.

    Full Text Available A 68-year-old Caucasian female with a past medical history of a deceased donor kidney transplant four months prior was admitted with a two-day history of anuria and acute kidney injury. A renal ultrasound demonstrated thrombus in the transplanted kidney's renal vein that extended into the left iliac vein as well as into the left femoral venous system. Catheter-guided tissue thrombolytics were infused directly into the clot. Within twelve hours of initiating thrombolytic infusion, there was brisk urine output. Interval venography demonstrated decreasing clot burden. At the time of discharge her creatinine was 0.78 mg/dL, similar to her baseline value prior to presentation. The patient was noted to have May-Thurner syndrome on intravascular ultrasound (IVUS. Angioplasty followed by stent placement was done. Unique to our case report was the timing of the presentation of renal vein thrombosis (four months after transplant and the predisposing anatomy consistent with May-Thurner syndrome, which was diagnosed with IVUS and successfully treated with local thrombolytics.

    A reptile holder based in the Czech Republic was bitten into his hand and foot by the Northeast saw-scaled viper (Echis pyramidum). The person arrived at the health institution after twenty hours for anuria. Despite the antivenom against the Asian Echis carinatum - the Echis pyramidum's close relative - was readily available and administered repeatedly, the envenoming continued to develop with subsequent coagulopathy, hepatopathy and respiratory failure. The effects of plasmapheresis and symptomatic therapy were positive, but only temporary. Continual renal replacement therapy and plasmapheresis were complicated by thrombotic occlusions of the device tubing set. A turning point arrived following repeated application of imported antivenom containing antigens against venom components of another African saw-scaled viper species, Echis leucogaster (the antivenom containing E. pyramidum antigens was not available). The clinical status, including complications, resolved following 30 days of hospitalization. The case further validates the geographical specifics of immunogenicity of venom components with similar clinical action in snakes of the same genus. PMID:21978783

    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.) With 4 figs., 16 refs.

  10. Role of radiopharmaceutical renal function studies in the medical surveillance of patients with transplanted kidneys

    International Nuclear Information System (INIS)

    In a study group of 35 patients having received a total of 37 kidneys 204 renal function scintiscans were obtained following administration of 99mTc DTPA and analysed with regard to the question as to whether radiopharmaceutical investigations using a gamma camera are a useful auxiliary tool to detect and diagnose functional disorders in the transplant that occur soon after surgery. In all of 13 patients showing complications in the form of prolonged anuria or oliguria during a period of up to 14 days following surgical intervention, the renal function scintiscans either permitted as firm diagnosis to be established or revealed conclusive findings that pointed to the necessity of further specific tests. Long-term follow-up studies carried out in 33 individuals failed or were slow to reveal acute or chronic rejection processes in one quarter of the patients, whereas the renal function scintiscans gave the earliest warning of functional disorders, unfavourable developments and complications in another quarter of patients; in the remaining part, the test results were in keeping with the clinical findings. Renal function scintiscans were thus judged to be a valuable diagnostic tool to ascertain and identify disorders occurring soon after surgery as well as to detect the early signs of functional disorders in the transplant during long-term follow-up studies. In view of the fact, however, that the sensitivity of the method in this field of application only is of the order of 75%, further research work appears to be required here. (TRV)

MATERIALS AND METHODS: 70 cases admitted at VIMS, Bellary during the period January 2012 to june 2013, with clinical evidence of acute renal failure were included in the study. They were evaluated for various etiological, prognostic factors and its outcome. RESULTS: Among the various aetiologies in our study, snake bite (28.6%, ADD (27.1%, RPGN (7.1% were the most common. Most common type of renal failure was prerenal (50%, among them ADD was the predominant cause followed by intrinsic failure (47%, among them snake bite was leading cause. Patients presenting with Anuria, late presentation to hospital, blood pressure 3mg had poor outcome. CONCLUSION: Amongst the etiological factors snake bite and ADD ranked first. Prognosis was determined by age, aetiology of renal failure, initial creatinine value, blood pressure, time of presentation to. Even though both snake bite and ADD are equally common causes, morbidity is more in snake bite and cost of treatment also more in snake bite as many of them require dialysis.

    Background The incidence of urinary lithiasis following kidney transplantation is very low, and decision-supporting data are not available. The aim of this study was to review the diagnosis and treatment of urinary lithiasis following kidney transplantation, which is of realistic significance to reduce urinary lithiasis following kidney transplantation, prolong the survival of renal allografts.Methods The incidence, diagnosis and treatment of urinary lithiasis in ten patients following kidney transplantation were analyzed retrospectively. Seven out of these patients had stones sized approximately 0.4-1.1 cm, and they were treated with low-voltage, low-frequency extracorporeal shock-wave lithotripsy (ESWL). Two patients had stones sized <0.3 cm and they underwent cystoscopy and ureteroscopy. The ureteral catheter endoscopes were inserted in a retrograde manner to mobilize stones repeatedly. After elimination of obstruction, a ureteral double J stent was indwelt.One patient had a pelvic stone (1.2 cm), which was removed surgically.Results The major clinical manifestations were hematuria, oliguria or anuria. Some patients were asymptomatic and they were diagnosed through laboratory tests and imaging examinations, e.g., ultrasonography. After elimination of obstruction, subjective symptoms disappeared in all patients, and the function of renal allografts recovered. A six-month follow-up indicated no remnant stones or lithiasis relapse.Conclusions The diagnosis and treatment of renal allograft lithiasis are challenging. After prompt and appropriate treatment, the prognosis was satisfactory, and permanent renal functional impairment did not occur in most patients.

    A case of Red-bellied Black snake envenomation resulting in intravascular haemolytic anaemia, rhabdomyolysis and anuric renal failure is described in the dog. A 12-year-old female desexed Golden Retriever was presented with a 15 hour history of profuse salivation, progressive lethargy, obtundence, inappetence and collapse. Significant findings on clinical examination were pallor, icterus, tachypnoea and dyspnoea with increased respiratory sounds and crackles in all lung fields. Generalised abdominal and muscular pain was apparent and dark red-brown urine was present around the perineal region. A diagnosis of Red-bellied Black snake (Pseudechis porphyriacus) envenomation was made and the dog was treated with intravenous fluid therapy, Tiger/Brown snake antivenom, packed red cell transfusions and Intermittent Positive Pressure Ventilation. Continued clinical deterioration occurred and a diagnosis of acute renal failure secondary to myohaemoglobinuric pigmenturia was made 12 hours after admission. Intensive treatment was attempted with diuresis and volume expansion. Oliguria and subsequent anuria ensued and the dog was euthanased due to a grave prognosis and lack of clinical response to treatment. Necropsy examination revealed muscular necrosis, accumulation of fluid in the thoracic and peritoneal cavities, and marked renal tubular necrosis with intraluminal occlusion secondary to pigmentary casts.

    Full Text Available Abstract Background The differentiation of the nature of a fluid collection as a complication of kidney transplantation is important for management and treatment planning. Early and delayed radionuclide renography can play an important role in the evaluation of a urine leak. However, it is sometimes limited in the evaluation of the exact location and extent of a urine leak. Case Presentation A 71-year-old male who had sudden anuria, scrotal swelling and elevated creatinine level after cadaveric renal transplantation performed Tc-99 m MAG3 renography to evaluate the renal function, followed by an ultrasound which was unremarkable. An extensive urine leak was evident on the planar images. However, an exact location of the urine leak was unknown. Accompanying SPECT/CT images confirmed a urine leak extending from the lower aspect of the transplant kidney to the floor of the pelvic cavity, presacral region and the scrotum via right inguinal canal as well as to the right abdominal wall. Conclusions Renal scintigraphy is very useful to detect a urine leak after renal transplantation. However, planar imaging is sometimes limited in evaluating the anatomical location and extent of a urine leak accurately. In that case accompanying SPECT/CT images are very helpful and valuable to evaluate the anatomical relationships exactly.

    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.

    Objective: To evaluate the efficacy and safety of holmium YAG laser lithotripsy for the treatment of ureteral calculi. Methods: A total of 356 patients underwent ureteropyeloscopic lithotripsy using holmium YAG laser with a semirigid uretesopyeloscope, 93 upper, 135 middle, and 128 lower ureteral stones were treated. Results: The overall successful fragmentation rate for all ureteral stones in a single session achieved 98% (349/356). The successful fragmentation rate stratified by stone location was 95% 88/93 in the upper ureter, 99% (134/135) in the mid ureter , and 99%(127/128) in the distal ureter. 12 cases with bilateral ureteral stones which caused acute renal failure and anuria were treated rapidly and effectively by the holmium YAG laser lithotripsy. No complications such as perforation and severe trauma were encountered during the operations. 2 weeks 17months (with an average of 6.8 month ) follow up postoperatively revealed that the overall stone-free rate was 98%(343/349) and no ureteral stenosis was found. Conclusions Holmium YAG laser lithotripsy is a highly effective, minimally invasive and safe therapy for ureteral calculi. It is indicated as a first choice of treatment for patients with ureteral calculi, especially for the ones with mid- lower levels of ureteral calculi.

    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 thromboplast in 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 conservatively. 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. PMID:24969215

    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.

    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.

  2. Obstetrical acute renal failure: a challenging medical complication

    International Nuclear Information System (INIS)

    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)

    Full Text Available The article presents some results of the research that are aimed at identifying specific realization of grammatical norms of the Church Slavonic language (Russian edition of the XV – beginning of XVI century. In Hagiography 'Life of Saint Anuria of the Desert', which is included into "Sobornik of the Greek Saints' lives" by St. Nilus of Sora, functional-semantic specificity of the forms of the past tense is defined. It is established that in the Hagiography all possible preterit forms are used: aorist, imperfect, perfect, pluperfect. On the example of aorist and imperfect forms' usage it is proved that they implement not only the original semantics, but also the meanings, that are characteristic of other preteritum. Due to the context the aorist form can express the following aeristhesia meanings: specifically factual (when referring to a specifically singled undifferentiated actions attributable to the past and without any connection with reality, specifically processional (if the characteristic of a specific condition or process is associated with a specific moment in the past, and perfect (in case of designating condition at the moment of speech, which was the result of actions in the past, pluscuamperfecto (when referring to actions that preceded another past action and imperfective (when referring to either long-term, continuous or repeated action in the past. The imperfect is used not only in its original meaning (long-term, repeated action or state, but also in the meanings of other preterito, in particular of the aorist. The mixture of past tense forms indicates a change in the nature of strict grammatical rules and the emergency of new grammatical rules of the Church Slavonic language (Russian edition.

    BACKGROUND Unexplained renal insufficiency combined with hepatic failure is a common problem encountered by clinicians. As with many disease processes involving multi-organ systems, reversible causes are usually not readily identifiable, and for many patients their health deteriorates rapidly. We present a rare cause of acute renal failure and hyperbilirubinemia occurring simultaneously, with leptospirosis presenting as Weil's disease. CASE REPORT A 53-year-old male presented to our clinic with complaints of anuria over the past two days. His symptoms started with dark urine, severe cramps in the thighs, and chills. The patient was a visitor to the United States from Guyana. Positive physical examination findings included mild tachycardia and hypotension, scleral icterus, and tenderness over abdomen, costovertebral angles, and thighs. The patient had a high white blood cell count, thrombocytopenia, renal/hepatic insufficiency, and an urinary tract infection (UTI). The patient was initially treated under the suspicion of acute kidney injury secondary to rhabdomyolysis and pyelonephritis. The patient continued to deteriorate with decreasing platelet counts, worsening renal function, hyperbilirubinemia, and respiratory distress, with no improvement with hemodialysis. Broad-spectrum antibiotics were administered, including doxycycline, due to a high suspicion of leptospirosis. The patient's condition drastically improved after initiation of doxycycline. On subsequent days, the patient's Leptospira antibody results were available, showing titers of more than 1:3200. Hemodialysis was discontinued as the patient started producing urine with improved kidney function. CONCLUSIONS As world travel becomes more economically feasible, we will continue to encounter foreign endemic diseases. Leptospirosis presenting as Weil's disease is a common cause of renal and hyperbilirubinemia in endemic areas. Often, as was the case for our patient where the time from presentation to acute

    Full Text Available We present the first report of a case of fibrillary glomerulonephritis (FGN associated with thrombotic microangiopathy (TMA and anti-glomerular basement membrane antibody (anti-GBM antibody. A 54-year-old man was admitted to our hospital for high fever and anuria. On the first hospital day, we initiated hemodialysis for renal dysfunction. Laboratory data revealed normocytic-normochromic anemia with schistocytes in the peripheral smear, thrombocytopenia, increased serum lactate dehydrogenase, decreased serum haptoglobin, and negative results for both direct and indirect Coombs tests. Based on these results, we diagnosed TMA. Assays conducted several days later indicated a disintegrin-like and metalloprotease with a thrombospondin motif 13 (ADAMTS13 activity of 31.6%, and ADAMTS13 inhibitors were negative. We started plasma exchange using fresh frozen plasma and steroid pulse therapy. Anti-GBM antibody was found to be positive. Renal biopsy showed FGN. Blood pressure rose on the 46th hospital day, and mild convulsions developed. Based on magnetic resonance imaging of the head, the patient was diagnosed with reversible posterior leukoencephalopathy syndrome. Hypertension persisted despite administration of multiple antihypertensive agents, and the patient experienced a sudden generalized seizure. Computed tomography of the head showed multiple cerebral hemorrhages. However, his blood pressure subsequently decreased and the platelet count increased. TMA remitted following 36 plasma exchange sessions, but renal function was not restored, and maintenance hemodialysis was continued. The patient was discharged on the 119th day of hospitalization. In conclusion, it was shown that TMA, FGN and anti-GBM antibody were closely related.

    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.

  13. Computerized technique for evaluating renal transplant function

    International Nuclear Information System (INIS)

    This investigation was undertaken to improve the assessment of renal transplant function in the early post-operative period when the usual measures of renal function afford little useful information. A simplified mathematical model of I-131 hippurate transport allows separation of renal uptake and excretion. Uptake (U) is defined as the fraction of I-131 hippurate in the plasma picked up by the kidney per minute, and excretion (E), the fraction of I-131 hippurate in the kidney excreted into the bladder per minute. Scintillation camera data from the region of the renal allograft are framed at 4/min by a computer system for up to 30 minutes post injection. After regions of interest are flagged over the kidney, bladder and background regions, the activity-time curves are analyzed, and values for U and E are output in a report updated through punched paper tape for any values from previous studies. The entire analysis of a patient study requires about 5 minutes of technologist time. Over 150 studies on 24 patients have been analyzed using the above technique. In the immediate post-operative state when anuria or severe oliguria is often present, sequential estimation of U was found to be a sensitive measure of renal transplant viability. In the period beyond one week reductions in U and E appeared to be sensitive measures of rejection, while increases in U and E heralded amelioration of the rejection episode. Changes in U and E appeared to be more sensitive measures of changes in renal function than routine qualitative scintiphotographic analysis. This technique has proven useful in following the renal function status of the kidney transplant recipient through acute tubular necrosis and rejection episodes and has been a significant adjunct to routine scintigraphy

    In the present study we conducted proteomic and pharmacological characterizations of the venom extracted from the Brazilian tarantula Acanthoscurria paulensis, and evaluated the cardiotoxicity of its two main fractions. The molecular masses of the venom components were identified by mass spectrometry (MALDI-TOF-MS) after chromatographic separation (HPLC). The lethal dose (LD(50)) was determined in mice. Nociceptive behavior was evaluated by intradermal injection in mice and the edematogenic activity by the rat hind-paw assay. Cardiotoxic activity was evaluated on in situ frog heart and on isolated frog ventricle strip. From 60 chromatographic fractions, 97 distinct components were identified, with molecular masses between 601.4 and 21,932.3 Da. A trimodal molecular mass distribution was observed: 30% of the components within 500-1999 Da, 38% within 3500-5999 Da and 21% within 6500-7999 Da. The LD(50) in mice was 25.4 ± 2.4 μg/g and the effects observed were hypoactivity, anuria, constipation, dyspnea and prostration until death, which occurred at higher doses. Despite presenting a dose-dependent edematogenic activity in the rat hind-paw assay, the venom had no nociceptive activity in mice. Additionally, the venom induced a rapid blockage of electrical activity and subsequent diastolic arrest on in situ frog heart preparation, which was inhibited by pretreatment with atropine. In the electrically driven frog ventricle strip, the whole venom and its low molecular mass fraction, but not the proteic one, induced a negative inotropic effect that was also inhibited by atropine. These results suggest that despite low toxicity, A. paulensis venom can induce severe physiological disturbances in mice.

    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.

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

    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

    Full Text Available Abstract Background The main hypothesis of this study is that neutral pH, low glucose degradation product (GDP peritoneal dialysis (PD fluid better preserves residual renal function in PD patients over time compared with conventional dialysate. Methods/Design Inclusion criteria are adult PD patients (CAPD or APD aged 18-81 years whose first dialysis was within 90 days prior to or following enrolment and who have a residual GFR ≥ 5 ml/min/1.73 m2, a urine output ≥ 400 ml/day and an ability to understand the nature and requirements of this trial. Pregnant or lactating patients or individuals with an active infection at the time of enrolment, a contra-indication to PD or participation in any other clinical trial where an intervention is designed to moderate rate of change of residual renal function are excluded. Patients will be randomized 1:1 to receive either neutral pH, low GDP dialysis solution (Balance® or conventional dialysis solution (Stay.safe® for a period of 2 years. During this 2 year study period, urinary urea and clearance measurements will be performed at 0, 3, 6, 9, 12, 18 and 24 months. The primary outcome measure will be the slope of residual renal function decline, adjusted for centre and presence of diabetic nephropathy. Secondary outcome measures will include time from initiation of peritoneal dialysis to anuria, peritoneal small solute clearance, peritoneal transport status, peritoneal ultrafiltration, technique survival, patient survival, peritonitis rates and adverse events. A total of 185 patients has been recruited into the trial. Discussion This investigator-initiated study has been designed to provide evidence to help nephrologists determine the optimal dialysis solution for preserving residual renal function in PD patients.

    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.

    , comparable to that of the two control groups treated with catheterization with a cystoscope or by medication. There was no significant difference in the recovery time of renal function among the three groups (P>0.05).Conclusions Melamine-contaminated milk formula may cause urinary stones and obstructive acute renal failure in infants. Dialysis is suggested to treat life-threatening complications such as hyperkalemia, oliguria or anuria if surgical intervention fails. If possible, hemodialysis or peritoneal dialysis can be performed early. Blood purification is feasible to help the infants overcome the critical stage of acute renal failure. Surgical measures can be taken to remove the obstruction if necessary.

    Background There was a hospital outbreak of venous diethylene glycol poisoning in Guangzhou, China. It is the only massive episode of venous diethylene glycol poisoning in history. Here we report its clinical features, laboratory findings, and imaging appearances.Methods The clinical features of 15 venous diethylene glycol poisoning patients with liver disease were analyzed and summarized. Their laboratory findings and imaging appearances were comparatively analyzed before and after poisoning.Results All poisoned patients presented with oliguric acute renal failure with anuria after a mean of 6 days. Carbon dioxide combination power of 13 patients dropped after a mean of 9 days with valley value on the 10th day, when metabolic acidosis developed. Gastroenteric symptoms or aggravation of gastroenteric symptoms were displayed in 11 patients after a mean of 9 days. Neurological system impairment was observed in 10 patients after a mean of 14 days. Seven patients had low fever after a mean of 6 days. Causes of death of 14 patients included multiple organ dysfunction syndrome, severe lung infection and massive haemorrhage of digestive tract. Blood creatinine and urea nitrogen were abnormal after a mean of 5 days with peak value on the 11th and 14th days, respectively. Serum calcium had no obvious change, and phosphorus was distinctively increased. Liver functions did not change significantly. Poisoned patients had higher white blood cell counts, but lower red blood cell counts and hemoglobin value. Of the 7 patients who exhibited mild, moderate or severe patchy consolidation shadowing in the lung, 2 manifested mild or severe gaseous distention and dilation of gastroenteric tract.Conclusions Main features of venous diethylene glycol poisoning in patients with liver disease include oliguric acute renal failure, metabolic acidosis, gastroenteric symptoms or aggravation of gastroenteric symptoms, neurological system impairment and low fever, with a mortality rate of 93

    Objective To investigate risk factors associated with acute tumor lysis syndrome (ATIS) in children with B-cell lymphoma and to explore feasible means for the prophylaxis and treatment.Method Data from 18 children with ATLS in B-cell lymphoma were collected to assess their tumor burden at diagnosis and before chemotherapy. Evaluation was performed at the 8th day, 3 month, and the end of chemotherapy and follow up. The incidence of ATLS in B-cell lymphoma, and the relationship between the incidence of ATLS and whether the kidney was involved and large tumor burden were analyzed respectively.All patients received hydration, alkalinization and received allopurinol routinely. Urate oxidase and hemodialysis treatment were administered in some cases. Result Of the 103 children with B-cell lymphoma, 18 were diagnosed as having ATLS (17.5%). All the 18 cases with ATLS were histopathologically confirmed as having Burkitt's lymphoma. All the patients were at stage Ⅲ or Ⅳ and all had large tumor sizes, and 7 were found to have blasts in the bone marrow > 25% ( 38. 9% ). Lactate dehydrogenase (LDH) levels ≥1000 U/L were found in 11 (61.1%) cases. All patients had developed metabolic abnormalities, including hyperuricemia, hyperphosphatemia, hypocalcemia , and uremia. In terms of clinical features and prognosis, all cases had nausea, vomiting, anorexia, oliguria, and anuria at different levels. One had gastrointestinal bleeding, 7 patients experienced seizures. The etiology in five was hypocalcemia and two had reversible posterior encephalopathy syndrome and all responded well to treatment.Nine cases of ATLS responded to supportive care, 4 required hemodialysis, and the other 4 responded to urate oxidase. Ten cases survived and 8 died. The major cause of death was severe complications and treatment was given up in 5 cases and recurrence occurred in 3 cases. Conclusion ATLS was commonly seen in Burkitt's subtype of B-cell lymphoma. Higher LDH and large tumor sizes and

    a history of abdominal pain, pallor, lethargy, and anuria for 36 hours. On physical examination, the patient showed malnutrition, high blood pressure, moderate edema, and hypochondrial pain. Laboratory findings included: urea=112mg/dl, serum creatinine= 4.5 mg/dl, blood pH= 7.47, blood bicarbonate= 12.8 mmol/L, K=7.2 mEq/L. Peritoneal dialysis was started and maintained for 11 days. After 7 weeks, the patient still needed anti-hypertensive drugs and the renal function was still abnormal. Renal biopsy was performed and revealed renal infarction. The result of Doppler ultrasonography revealed absent renal blood flow on the right side. Renal arteriography showed total occlusion of the right renal artery. Results for collagen diseases were negative. A right nephrectomy was performed and the blood pressure was controlled. The child was hospitalized again at 5 years and 8 months old with episodes of absence seizures and abdominal and precordial pain. Anticardiolipin antibody test was positive. The child is now 7 years old, asymptomatic, with negative anticardiolipin antibody, and has been under regular follow-up. COMMENTS: children with arterial thrombosis should be investigated for a possible association with the antiphospholipid antibody syndrome even in the absence of collagen disease.

    Objective: To investigate the clinical and pathological manifestation of acute kidney injury ( AKI) following infusion of clindamycin. Methodology: From Aug, 2008 to Mar, 2011, twenty two patients were diagnosed as the infusion of clindamycin induced AKI. All of patients met the following three criteria; ( 1 ) No previous history of underlying chronic kidney disease; (2) the AKIN critieria of AKI soon after the infusion of clindamycin; (3) No obvious other cause of AKI, e. G. Volume insufficency, septic shock, urinary obstruction, etc. The clinical and pathological manifestations of these patients were investigated. Results-.They were 13 males and 9 females, with an average of (44. 46 ±11. 53 ) ( ranged from 20 to 70 ) years old. The reasons of clindmycin therapy were upper respiratory infection, toothache, and routine anti-infection therapy after minor operation with a usual dosage of 1. 0 ~ 1. 5 g/d. The median time between administration of drug and onset of AKI was one day (0. 5h ~4d). The most frequent chief complains were nausea and vomiting( 54. 55% ), lumbodynia ( 22. 73% ) , abdominal pain ( 22. 73% ) and edema ( 13. 64% ). Oliguria was in 13(59. 09% )and anuria in 7 patients(31. 82% ). Sixteen patients(72. 73% ) had episodes of gross hematuria, while only 3 patients(13. 64% ) encountered fever and one (4. 55% ) had skin rash. Laboratory examinations revealed anemia in 16 (72. 73% ) patients,but eosinophilia was not detected. Nineteen(90. 91% ) patients were diagnosed as AKI 3 stage, the others were as AKI 1 stage on admission. Urine analysis sowed mild proteinuria (0. 44 ± 0. 35) g/24h and severe tubular function injury. Urine eosinophilic cell was positive in only one case, and uniform microscopic hematuria was positive in 3 cases. Clindamycin lymphocyte transformation assay was positive in 13/16 (81. 25% ).

    , slow development of renal dysfunction and failure. With the improvement of living standards, living environment changes, chronic renal failure (including diabetic nephropathy) the incidence rate has been increasing, more and more young age, number of people in hemodialysis is also increasing, seriously affecting the quality of life of patients, resulting in huge economic losses to the state. In recent years, show who survey, the incidence of chronic kidney disease in the global rate gradually increased, have after cardiovascular disease, cancer, diabetes and a threat to the health of major diseases. The situation of chronic kidney disease was serious in China, according to people over the age of 40 preliminary investigation of chronic kidney prevalence rate of 8%---9%. And other hazards Compared with the major diseases to human health, performance of chronic kidney disease more insidious onset, no obvious symptoms, many patients began treatment have become chronic renal failure uremia patients with uremia until, average annual medical costs about 5----10 million yuan, high treatment cost bring a heavy burden to bear to the society and families, many so "family poverty, returning to poverty due to illness". Western medicine treatment can not only solve the early injury of kidney, urinary protein and early renal dysfunction cannot be alleviated. Traditional Chinese medicine believes that this disease is the disease for a long time is false and renal failure. Renal failure (edema) refers to kidney and renal injury by a sudden illness, or disease, caused by long, kidney failure, Qi dysfunction, wet and muddy uremic shall not be discharged, to quickly oliguria or anuria, eyelid swelling and edema of the lower extremities, lusterless complexion, depressed. Divided into renal failure early (compensatory period), Renal failure stage (decompensation and failure stage), renal failure (uremia) late. Western traditional treatment is early symptomatic treatment, advanced
