RESUMO
BACKGROUND: The population-based survival rate is affected by the quality and effectiveness of health care systems. Overall, the survival of prostate cancer (PC) patients has improved over the past two decades worldwide. This study aimed to determine the overall survival rate and correlate it with the prognostic factors in patients with PC diagnosed in Kurdistan province. METHODS: In a retrospective cohort study, 410 PC patients registered in Kurdistan province population-based cancer registry from March 2011 to 2018 were recruited. Kaplan-Meier method and log-rank test were used to analyze the overall survival rates of PC patients. A Multivariate Cox regression model was used to determine adjusted hazard ratios for different variables. RESULTS: Of 410 patients with PC, 263 (64.1%) died within seven years due to the disease. The 1, 3, and 5 years survival rates were 93, 64.1, and 40.7%, respectively. According to the results of multiple Cox regression, the following factors were significantly related to PC survival: age at diagnosis (≥81-years old) (HR=2.23, 95% CI: 1.23-4.42) and 71-80 years old was (HR=1.26, 95% CI: 1.12-2.31), occupation (employee) (HR=0.42, 95% CI: 0.20-0.87), educational level: academic (HR=0.78, 95% CI: 0.64-0.91), AJCC stage of disease (HR=2.18, 95% CI: 1.9-3.68), Gleason score ≥ 9 (HR=7.12, 95% CI: 5.35-10.28), and Gleason score= 8 (HR=4.16, 95% CI: 2.50-6.93). There was less mortality rate among the patients who had received active care, radical prostatectomy, radiotherapy, combined treatment, and orchiectomy had a lower mortality rate than those who received no treatment (P<0.05). CONCLUSIONS: This study demonstrated that factors such as age at diagnosis, level of education, occupation, AJCC stage of disease, Gleason score, and type of treatments were influential factors in the survival of PC patients in Kurdistan province and needed more attention.

PURPOSE: Urological complications are common and serious in kidney transplant patients. Correct diagnosis of urological complications and rapid intervention are very important to maintain the transplanted organ. Using endoscopic methods and rapid access to ureteral orifice can be effective in treatment and management of urological complications in transplant patients. MATERIALS AND METHODS: In this retrospective cohort study, 934 medical records of kidney transplant patients who underwent surgery through Posterolateral Extravesical Ureteroneocystostomy (PLEVUNC) and anterior extravesical ureteroneocystostomy (AEVUNC) techniques from 2011 to 2018 were evaluated. The outcomes of PLEVUNC and AEVUNC techniques were evaluated in 461 and 473 transplant patients, respectively. The patients were followed up for 60 months. Immediate and delayed complications, urological complications requiring endoscopic intervention, duration of access to ureteral orifice, as well as ureteroscopic and endoscopic outcomes were evaluated. RESULTS: The mean and ± SD (standard deviation) age of patients in PLEVUNC and AEVUNC groups were 46.2 7± 2.7 years and 47.3 ± 3.6 years, respectively. Urinary leakage and UTI were the most common immediate (7% and 6.2%) and delayed (5.5% and 5.5%) complications in both groups, respectively. The time to find ureteral orifice in patients requiring endoscopic intervention was significantly shorter in PLEVUNC group 3.5±1.2 compared with the AEVUNC group 10 ± 4.5 (P <.001). In 100% of PLEVUNC group and 62.6% of AEVUNC group, ureteral orifice of transplanted kidney was observed (P <.001). Ureteroscopy was reported successful in 94.5% and 37.4% of patients in PLEVUNC and AEVUNC groups, respectively. CONCLUSION: Easy and safe access to the ureteral orifice and to the upper urinary tract in transplant recipients can be achieved with the PLEVUNC technique. In case of urological complications this method facilitates endoscopy.

PURPOSE: With the invention of miniature devices, it has been advised to apply less aggressive methods for the management of upper urinary tract stones, especially in children. In the recent years, ultra-mini percutaneous nephrolithotomy (UMP) has been used for the treatment of upper urinary tract stones in order to perform surgeries with less complications and more acceptable outcomes. Results reported from different medical centers have been promising. MATERIALS AND METHODS: Twenty-two children aged less than 8 years old with upper urinary stones sized between 10-20 mm underwent UMP. Inclusion criteria was solitary unilateral kidney stone, stone size between 10-20 mm, normal renal function tests, absence of any congenital malformations, and history of previous ESWL failure. Data including age, sex, side of kidney involvement, size of stone, location of stone, duration of surgery, duration of hospitalization, stone composition, need for blood transfusion, damage to adjacent organs, postoperative fever, septicemia after surgery, need for narcotics, further need for a complementary method, stone-free rate, pre and post-operative hemoglobin levels, and urinary leakage from the access tract were extracted from patients' medical files and were recorded. RESULTS: The mean age (± standard deviation) of children was 5.22 (±1.57) years. Fourteen (63.6%) patients were male. Fifteen (68.2%) renal stones were located in the right kidney, and 82% of patients had pelvis stones. 13 (59%) patients' stones were composed of calcium oxalate. Stone-free rate was 95.5%. In none of the cases urinary leakage, septicemia after surgery, injury to adjacent organs, and need for blood transfusions was reported. CONCLUSION: Ultra-mini percutaneous nephrolithotomy is an efficient and safe method for treating urinary stones sized between 10-20 mm in children.

PURPOSE: The aim of this study was to evaluate the efficacy of transvesical open prostatectomy (OP) compared with transurethral resection of the prostate (TURP) in patients with benign prostate hyperplasia (BPH) with a prostate weight of 40-65 grams. The short-term and long-term complications of these two procedures were also assessed. MATERIALS AND METHODS: In this retrospective study, we included 160 consecutive patients with BPH who had undergone TURP (n=80) or OP surgery (n=80) from 2006 to 2017. Inclusion criteria were positive history of BPH, definite indication for prostatectomy, and prostate weight between 40 to 65 grams. Patients were evaluated for duration of hospitalization, need for re-operation, short-term and long-term postoperative complications, urinary flow rate, peak flow rate (Q max) and international prostate symptom score (IPSS). RESULTS: The mean age ± Standard Deviation (SD) of patients' age was 62.4 ± 3.7 and 67.2 ± 4.6 years in the TURP and OP groups, respectively. Four (5%) and seven (8.7%) patients required transfusion in the TURP group and OP groups, respectively. Dysuria was significantly more frequent in the TURP group from week two to 12 months after surgery as compared with the OP group (P < .001). Hemodynamic changes and decrease in serum sodium level were not reported in either group. However, the urinary retention and need for urinary catheterization in the first year was significantly different between the two groups with 10 cases (12.5%) in the TURP group and no cases in the OP group (P<0.001). The need for reoperation in the TURP group was reported (27 procedures on 19 patients) (33.7%) of patients. Furthermore, retrograde ejaculation (RE) was reported in 65 (81.2%) and 80 patients (100%) of the TURP and OP group, respectively. CONCLUSION: Despite the fact that TURP is the standard method of treatment for BPH when the prostate weighs between 40-65 grams, the results of our study showed that OP is a more efficient and safe surgery for these patients and is associated with less complications. Furthermore, the need for re-operation seems to be higher in patients with TURP.

BACKGROUND: Varicocele is defined as dilated and twisted veins of the pampiniform plexus in the spermatic cord. It is the most common cause of male infertility. There are various medical and surgical procedures for the treatment of this disease. AIM: This study was aimed to compare the effects of oral administration of L-Carnitine and varicocelectomy on spermogram parameters. MATERIALS AND METHODS: This study was conducted as a double blind clinical trial without randomization. Inclusion criteria were, all married infertile men with varicocele. Patients chose their treatment personally and spermogram was carried out for all patients before and after the third and sixth months of treatment. Then, the sperm parameters of the two groups were compared using repeated measures ANOVA. RESULTS: In our study, trend of sperm count in the surgery group changed from 22 to 28.61 million (vs 34.6 to 45.37 in L-Carnitine group), motility changed from 21.74 to 35.38 percent (vs 33.9 to 47.48 in L-Carnitine group), normal sperm morphology changed from 46.25 to 60 percent (vs 56.61 to 69.7 in L-Carnitine group) and volume of semen changed from 3.5 to 4.17 cc (vs 2.95 to 4.33 in L-Carnitine group). These values were not statistically different between the two groups. CONCLUSION: Based on the results of this study, we can say that medicinal treatment by administration of oral L-Carnitine is as effective as varicocelectomy in improving semen parameters and can be used as an alternative to surgery for varicocele grade II.
RESUMO
PURPOSE: To investigate technical problems, complications and stone clearance rate in patients with spinal neuropathy who had undergone percutaneous nephrolithotomy. MATERIALS AND METHODS: This cross-sectional study was done between 2004 and 2013 on 29 patients with both spinal cord neuropathy and kidney stones who were chosen for percutaneous nephrolithotomy in Sanandaj city, Iran. The data were obtained from patients' medical records and were documented in a researcher-made checklist. Absolute and relative frequency, mean and standard deviation were calculated. RESULTS: A total of 43 percutaneous nephrolithotomies were performed on 32 kidneys. In 51.7% the right kidney, in 37.9% the left kidney and in three patients (10.3%) both kidneys were involved. There were 24 patients (82.8%) with spinal cord injury. Five patients (17.2%) had spina bifida. The mean of operation time was 129.7 minutes and the mean of hospital stay was 8.3 ± 3.1 days. The mean of kidney stone size was 35.7 ± 6.1 mm (25 to 45 mm). In 58.5% of the patients, surgery lasted more than two hours. Stone clearance rates were 53.1% and 78.1% after the first and second percutaneous nephrolithotomy. CONCLUSION: Although patients with spinal cord injury have problems in terms of surgery and complications, percutaneous nephrolithotomy is an appropriate and safe treatment method for their kidney stones. Pre-operative counseling with a radiologist and an anesthesiologist is recommended. .

BACKGROUND: Andropause is the gradual reduction of the male sex hormone (testosterone) with increasing age. Its symptoms are sexual dysfunction, weakness, fatigue, insomnia, loss of motivation, mood disorders and reduction of bone density. Treatment of andropause with testosterone has been recently considered. OBJECTIVES: The aim of this study was to evaluate the effect of testosterone in the treatment of andropause in men. PATIENTS AND METHODS: For men who met the inclusion criteria (50 years of age and older) laboratory tests and clinical examinations were conducted by an urologist in order to diagnose prostate cancer, prostate disease, urinary tract infection and active urinary retention. After obtaining consent, the patients were enrolled in the study. Data were analyzed using SPSS version 20. Descriptive statistics (frequency and percentage, mean, standard deviation) and the paired t-test were used to compare levels of testosterone. To determine the correlation between age and testosterone levels, the Pearson correlation was used. Finally, to compare the treatment processes during the treatment period the repeated measures ANOVA was used. RESULTS: The mean age of patients was 56.57 ± 3.21 years. A total of 31 patients (39%) were smokers, among them 30% smoked daily, 2.5% weekly and 6% smoked for fun. The mean testosterone level before treatment was 240.6 ± 125.4 and at 1, 3 and 6 months after treatment the level was raised, so that at the end of the sixth months it was 578.7 ± 141.7. The level of increase was statistically significant (P = 0.0001). CONCLUSIONS: Treatment with testosterone in men over 50 years with andropause will increase testosterone levels and also quality of life, sexual desire, erection, energy levels, ability to exercise and feel the joy of life more than before. Depression was decreased and they had sleepy feelings after dinner.
RESUMO
Uncontrolled self-renewal plays a direct function in the progression of different types of carcinomas. The same molecular pathway that manages self-renewal in normal stem cells also seems to manage cancer stem cells. Here, we examine the expressions of self-renewal regulatory factors Oct4, Nanog, Sox2, nucleostemin, Zfx, Esrrb, Tcl1, Tbx3, and Dppa4 in tissue samples of colon, prostate, and bladder carcinomas as well as cancer cell lines HT-29, Caco-2, HT-1376, LNCaP, and HepG2. We used reverse transcriptase polymerase chain reaction to examine expressions of the above mentioned regulatory factors in cancer cell lines HT-29, Caco-2, HT-1376, LNCaP, and HepG2 and in 20 tumor tissue samples. Total RNA was isolated by the ISOGEN method. RNA integrity was checked by agarose gel electrophoresis and spectrophotometry. Expressions of Oct4 and nucleostemin at the protein level were determined by immunocytochemistry. A significant relationship was found between tumor grade and self-renewal gene expression. Expressions of stem cell specific marker genes were detected in all examined cancer cell lines, in 40% to 100% of bladder cancer samples, and in 60% to 100% of colon and prostate cancer samples. Oct4 expressed in 100% of tumor tissue samples. Our data show that stem cell markers Oct4, Nanog, Sox2, nucleostemin, Bmi, Zfx, Esrrb, Tcl1, Tbx3, and Dppa4 significantly express in cancer cell lines and cancer tissues. Hence, these markers might be useful as potential tumor markers in the diagnosis and/or prognosis of tumors.
