    Background Recent years, morbidity of chronic prostatis is increasing in Mongolia. Most common cause of the chronic prostatis is Non-Gonococcal Urethritis (NGU) such as chlamydia trachomatis, mycoplasma hominis, mycoplasma genitalium, ureaplasma urealyticum and ureaplasma parvum or mixed infections. Purpose The purpose of the study was to research possible relationships between signs or symptoms of the chronic prostatitis and its cause. Method A total of 466 males who have possible signs of c...

    A total of 7 healthy volunteers and 31 patients have been examined clinically, by MRI, TRS, and biopsy. In those patients with established carcinoma, a CT examination was also performed. For the MRI study, a superconducting MR 2000 imager (Picker International) operated at 0.15 T was used with multiplanar SE and IR sequnces. SE sequences with long echo times detected prostatitis, adenoma and carcinoma of the prostate with a high degree of sensitivity. However, at present, differentiation between adenoma, prostatis and carcinoma is not possible with sufficient accuracy. In these studies we were unable to establish a correlation between the signal pattern and staging and/or grading of the carcinoma. Reliable diagnosis of a prostate carcinoma still requires a biopsy. Because of the high soft tissue contrast and the possibility of selecting any orientation for the plane under investigation, however, MRI represents an improvement in the preoperative diagnosis of local spread.

    US-guided biopsy was performed in 94 patients with suspected lesions at transerectal US. Histology demonstrated carcinoma in 43 cases, benign hyperplasia in 44, and prostatis in 7. In all cases the prostate specific antigen (PSA) was calculated, by means of US, together with prostatic volume (v). PSA was related to the corresponding gland volume, which resulted in PSA/V ratio. Our study showed PSA/V ration to have higher sensitivity and specificity than absolulute PSA value in the diagnosis of prostatic carcinoma. The authors believe prostate US-guided biopsy to be: a) necessary when the suspected area has PSA/V ratio >0.15, and especially when PSA/V >0.30; b) not indicated when echo-structural alterations are associated with PSA/V <0.15, because they are most frequently due to benign lesions. The combined use of PSA/V ratio and US is therefore suggested to select the patients in whom biopsy is to be performed

    To investigate the pathogenic infection and its drug resistance in expressed prostatic secretion (EPS) and its correlation with serum PSA, and provide some evidence for the systematic and normalized diagnosis and treatment of prostatitis. Three EPS swabs were collected from each of the 320 prostatis patients following measurement of the serum PSA level, 1 for bacterial culture and identification, 1 for detection of Mycoplasma and drug sensitivity, and the other for examination of Chlamydia trachomatis antigen by colloidal gold immunoblot. Totally 244 strains were isolated from the 320 EPS samples, including 188 bacterial strains (dominated by Staphylococcus and sensitive to vancomycin or linezolid) and 44 Mycoplasma and Chlamydia strains (mainly Ureaplasma urealyticum and susceptible to josamycin or doxycycline). The serum PSA level was significantly higher in the pathogen-positive than in the pathogen-negative group ([6.98 +/- 0.56] microg/L vs [2.32 +/- 0.12] microg/L, P Prostatitis may lead to the elevation of the serum PSA level and the pathogens involved vary in their resistance to different antibacterial spectrums. Therefore, appropriate and individualized antibiotic therapy should be selected according to etiological diagnosis and the results of drug sensitivity test.

    To evaluate the therapeutic effect of Compound Xuanju Capsule (CXC) on autoimmune prostatitis in rat models. Sixty healthy male Wistar rats were randomly divided into five groups of equal number: blank control, low-concentration purified prostate protein (low-conc PPP), low-conc PPP + CXC treatment, high-concentration PPP (hi-con PPP), and hi-conc PPP + CXC treatment. Autoimmune prostatitis models were established by intragastric administration of PPP solution at 15 mg/ml (low concentration) and 80 mg/ml, respectively. At 30 days after modeling, the rats in the blank control and low-conc and hi-conc PPP model groups were treated with normal saline, and those in the other two groups with CXC at a daily dose of 0.068 g/ml. At 30, 45, and 60 days, all the animals were sacrificed for observation of pathological changes in the prostate tissue and determination of the levels of IL-8, IL-10, and TNF-alpha in the serum. Compared with the PPP models, the hi-conc PPP + CXC group showed significantly reduced levels of IL-8 and TNF-alpha in the serum at 45 days ([148.54 +/- 17.23] and [62.14 +/- 5.59] pg/ml vs [100.77 +/- 11.08] and [32.63 +/- 2.91] pg/ml, P microscope. Compound Xuanju Capsule is efficacious on autoimmune prostatis in rats by reducing inflammatory changes in the prostate tissue and improving the expression of inflammatory factors.

    The main aim of this study is to compare two hypo-fractionated protocols used in the radiotherapy of prostate cancer in terms of late complications in normal tissue. 50 patients in first protocol were irradiated with the dose of 52,8 Gy in 16 fractions. 52 patients included in the second protocol were irradiated with the dose of 62 Gy in 20 fractions. Protocols were compared through dose-volume histograms (DVH) of rectum and bladder and radiobiological calculations with the use of Lyman-Kutcher-Burman model for Normal Tissue Complication Probability (NTCP). Results of NTCP were compared with real incidence of late toxicity for normal tissue. DVH of rectum and bladder for patients from second protocol have a better behavior then DVHs for patients from first protocol. NTCPs for first protocol are (12,5{+-}3,3)% and (1,6{+-}1,3)% for rectum and bladder, respectively. NTCPs for second protocol are (6,8{+-}3,0)% and (0,53{+-}0,9)% for rectum and bladder, respectively. From comparison of results of radiobiological calculations and real incidence had arisen a need of refinement of parameters of LKB model. (authors)
