The effectiveness of local steroid injection after internal urethrotomy to avoid recurrence.

OBJECTIVE: Local steroid injection to the stricture region after internal urethrotomy (IU) is a promising technique to avoid the recurrence, although the effectiveness and safety of this technique is still controversial. We aimed to determine the efficacy and safety of local steroids as applied with the IU procedure. MATERIAL-METHOD: A total of 83 patients data with urethral stricture in men were examined retrospectively. Patients classified in two groups who had steroid injection with internal urethrotomy or not. Metil prednisolone 40 mg was injected with transurethral injection needle in the stricture region at the 5, 7 and 12 o'clock sites at the same session with internal urethrotomy. Procedure was considered successful if patient did not report any voiding difficulty and maximum flow rate > 15 mL/second for a voided volume of at least 150 mL after removal of the catheter. Patient's age, time to recurrence, previous recurrences were evaluated. RESULTS: The mean age was 56.4 (18-83) years. Of those patients 33/83 had recurrent stenosis. Nineteen out of these 33 recurrent stenosis patients were treated with local steroid injection and 14/33 had no injection. Only two patients of the steroid treated group had recurrence. Despite that 12 patients had recurrence in the steroid non-treated group. Also the primary stenosis patients showed no recurrence at the steroid+ IU group. CONCLUSIONS: The use of local steroids with IU seems to decrease the high stricture recurrence rate following IU. When local steroids were administered with complementary intention, the disease control outcomes are encouraging. Further robust comparative effectiveness studies are now required.

Bladder cancer invasion predictability based on preoperative neutrophil-lymphocyte ratio.

An increased pretreatment neutrophil-lymphocyte ratio (NLR) is associated with poor prognosis in colorectal, gastric, and ovarian cancer; malignant mesothelioma; and renal cell carcinoma. The present study aims to define the predictive value of preoperative peripheral blood count NLR in non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive disease (MIBC) patients. There were in total 291 patients, 241 males and 50 females. Out of these, 156 male and 36 female patients were in the NMIBC group and 85 male and 14 female patients in the MIBC group. In the NMIBC group, 172 patients had low-grade and 20 high-grade papillary urothelial carcinoma. The mean age of the patients in the NMIBC group was 64 ± 13, ranging from 27 to 97. The mean age of the patients in MIBC group was 70.5 ± 10, ranging from 27 to 95. A statistically significant relation between patient ages and tumor invasiveness was determined (p = 0.023, 95 % confidence interval (CI) 63.3-66.7). The mean tumor size of the NMIBC group was 2.1 ± 1.09 (cm) (range 0.5-8), and of MIBC group 3.6 ± 1.5 (cm) (range 0.8-9). There was a statistically significant relation between the tumor size and invasiveness (p = 0.002, 95 % CI 2.8-4.4). In the NIMBC group, 149 (77.6 %) of them have NLR ≤ 2.5 and 43 (22.4 %) have NLR > 2.5. Also, in MIBC, 67 (67.7 %) of them have NLR ≤ 2.5 and 32 (32.3 %) have NLR > 2.5. The mean NLR in the NMIBC group was 2.4 ± 0.1 (range 0.08-6.49, 95 % CI 1.52-2.71) and in the MIBC 2.9 ± 0.2 (range 0.08-16.72, 95 % CI 1.67-2.97). In terms of NLR, there was a statistically significant difference between the NMIBC and MIBC groups (p = 0.028). Platelet-lymphocyte ratio (PLR) of the two groups was also analyzed. The PLR of the NMIBC group was 12.8 ± 15.1 (range 3.38-19.1) and of the MIBC 13.6 ± 8.78 (range 0.18-63), yet there was not any statistically significant difference (p = 0.810, 95 % CI 11.4-14.8) (Table 1). The correlation tests revealed a positive correlation between the age (r = 0.144, p = 0.024), tumor size (r = 0.193, p = 0.02), and tumor invasiveness NLR (r = 0.138, p = 0.031). NLR can be used to determine tumor invasiveness as a cost-effective, common, and simple biomarker in bladder cancer (BC).

CA 125 levels and left ventricular function in patients with end-stage renal disease on maintenance hemodialysis.

PURPOSE: The aim of this study was to analyze associations between serum cancer antigen 125 (CA 125) levels and left ventricular (LV) function in patients with end-stage renal disease on maintenance hemodialysis (HD). METHODS: CA 125 levels, pro-brain natriuretic peptide (pro-BNP) and biochemical parameters were measured, and echocardiography was performed for 110 patients and 47 healthy controls. RESULTS: The mean CA 125 level in patients, 38.78 ± 35.48 U/mL, was significantly higher than that found in healthy controls (9.20 ± 4.55 U/mL; p = 0.003). Patients with elevated CA 125 levels (n = 40) had significantly lower levels of albumin and reduced relative wall thickness, LV ejection fraction (EF) and fractional shortening but significantly higher levels of pro-BNP and a greater left ventricular end-diastolic diameter (LVEDd) and -systolic diameter (LVESd). CA 125 levels were positively correlated with pro-BNP (r = 0.596, p < 0.05) and C-reactive protein (CRP) levels (r = 0.439, p < 0.05), as well as LVEDd (r = 0.599, p < 0.001), LVESd (r = 0.750, p < 0.001) and LV mass index (r = 0.378, p < 0.05). In contrast, serum CA 125 levels were negatively correlated with albumin (r = -0.513, p < 0.05) and hemoglobin (r = -0.475, p < 0.05) as well as the EF (r = -0.878, p < 0.0001). A depressed EF (ß = -1.121, p < 0.0001) and increased CRP levels (ß = 0.247, p = 0.035) were independent predictors of high CA 125 levels in the whole group in the multivariate-model. CONCLUSIONS: Our study is the first to demonstrate an association between serum CA 125 levels and LV systolic dysfunction via inflammation in patients on maintenance HD.

Testicular fusion in a patient with crossed testicular ectopia: a rare entity.

Crossed testicular ectopia (CTE) is a well-described, rare congenital abnormality of testicular descent, in which both testes migrate through one inguinal canal. The objective of this work is to present a case of fused two testicles in a hemiscrotum as a rare entity of CTE. We describe a rare case of CTE in a 19-year-old boy presenting to the Department with left testis placed in the right hemiscrotum with right inguinal hernia. Ultrasound and magnetic resonance imaging revealed fused testes with their own vasa deferentia in the left hemiscrotum. Azoospermia was detected in semen analysis. The patient was referred to microTESE and ICSI procedure for his infertility problem. CTE should be kept in mind in patients with an inguinal hernia and contralateral nonpalpable testis.

Ovarian apoptosis after shock wave lithotripsy for distal ureteral stones.

The objective of this study is to identify any apoptotic effect of shock wave lithotripsy (SWL) for distal ureteral stones on ovarian tissue. Twenty-one female New Zealand White rabbits were divided into three groups of seven rabbits each: I (control), and II, III (treated and killed 14 and 28 days after SWL, respectively). The left distal ureteral segment of the anesthetized (ketamine HCl, 20 mg/kg) animals in groups II and III was exposed to 1,500 shock waves at 17 kV. Localization of the distal ureteral segments was achieved following contrast medium (Iohexol 300 mg of I/ml) injection. The animals were killed on day 14 or 28 after SWL, and the ovaries were removed. The follicle number with apoptotic changes in ovarian tissue was compared with control group. Apoptotic changes were determined by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end-labeling (TUNEL) method. No increased apoptosis was detected in all groups. The mean number of TUNEL-positive follicle in groups I, II and III was 9.3 +/- 2.9, 8.1 +/- 2.6 and 8.7 +/- 2.9, respectively. There were no statistically significant differences among all groups regarding the number of TUNEL-positive follicle (P = 0.647). Also, no histomorphological change other than apoptosis was detected in the study groups. In conclusion, SWL treatment for distal ureteral stones does not induce apoptotic changes on ovarian tissue.

The effect of dietary ginger (Zingiber officinals Rosc) on renal ischemia/reperfusion injury in rat kidneys.

Oxidative stress has been considered as one of the possible mechanisms of ischemia/ reperfusion (I/R) injury in the kidney. The aim of this study was to analyze the possible protective effect of dietary ginger (Zingiber officinals Rosc), a free radical scavenger, on renal I/R injury in rats. The protective effect of ginger against the damage inflicted by reactive oxygen species (ROS) during renal I/R was investigated in Wistar albino rats using histopathological and biochemical parameters. Thirty rats were randomly divided into five experimental groups (i.e., control, sham-operated, ginger, I/R, and I/R + ginger groups, n = 6 each). The ginger and I/R + ginger groups were fed on the test diet containing 5% ginger. The rats were subjected to bilateral renal ischemia followed by reperfusion in I/R and I/R + ginger groups. At the end of the reperfusion period, rats were sacrificed, and kidney function tests, serum and tissue oxidants and antioxidants, and renal morphology were evaluated. Serum urea, creatinine, and cystatin C (CYC) levels were significantly elevated in the ischemia group, but these levels remained unchanged in the ginger + I/R group compared to the I/R group. Reduction of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) enzyme activity was significantly improved by the treatment with ginger compared to I/R group. Administration of ginger resulted in significant reduction levels of tissue malondialdehyde (MDA), NO, protein carbonyl contents (PCC) in the ginger + I/R group compared with the I/R group. Ginger supplementation in the diet before I/R injury resulted in higher total antioxidant capacity (TAC) and lower total oxidant status (TOS) levels than I/R group. The ginger supplemented diet prior to I/R process demonstrated marked reduction of the histological features of renal injury. The findings imply that ROS play a causal role in I/R-induced renal injury, and ginger exerts renoprotective effects probably by the radical scavenging and antioxidant activities.

Serum adropin as a predictive biomarker of erectile dysfunction in coronary artery disease patients.

INTRODUCTION: Erectile dysfunction (ED) is associated with various comorbidities and an early diagnosis and treatment is necessary to avoid the development of these comorbidities. Unfortunately, there is no biochemical marker that can be used for early diagnosis of ED. Nitric oxide (NO) is released by nerve and endothelial cells in the corpora cavernosa of the penis and is believed to be the main vasoactive chemical mediator of penile erection. Adropin is a regulatory peptide which has effects on NO bioavailability and energy homeostasis. We hypothesized that adropin may contribute to the pathogenesis of ED because of the presence of both metabolic effects and the influence on NO bioavailability. To confirm this hypothesis, we investigated the relationship between ED and serum adropin and NO levels. MATERIAL AND METHODS: Seventy-five ED patients were enrolled for this study and the patients were divided into two groups according to angiographic scoring. Serum NO and adropin levels were measured by the Griess reaction and ELISA method, respectively. RESULTS: Serum adropin and NO levels were found to be lower in the group which has higher angiographic score and the difference in NO was statistically significant. Also, adropin has a significant correlation between IIEF scores in ED patients. CONCLUSIONS: This is the first study in the literature investigating the levels of adropin in ED patients having coronary artery disease. The adropin molecule shows a promising future in clarifying the etiopathogenesis of ED. More comprehensive and multicenter studies are needed to reveal the role of adropin in ED and the effects of treatment on this molecule.

Urological recommedations of Hadji Pasha's, a Turkish aged doctor in Anatolia.

OBJECTIVE: Urinary tract conditions have been an important part of diseases from antiquity until today. Historically, many plants and herbs have been used for the treatment of urinary disorders. METHODS: Celâlüddîn Hizir bin Ali el-Konevi (Hadji Pasha) is one of the most famous physician who lived in Anatolia between 13th and 14th centuries. He has written one of the most important medical books of that era, "Müntehab-iSifa" (solution of wellness) in Turkish. General medical information about the diseases in this book, focus on diagnosis and treatment. RESULTS: The herbal solutions for urological disorders such as, urinary incontinence, urinary stones or erection problems are told in this section. CONCLUSION: Many of the herbal medicines addressed in this book are being widely used in current medicine, but the usage of these herbals in daily urology practice is limited. In this study, we aimed to share the advices for the urological diseases and the related herbal medicines that are named in Hadji Pasha's book, "Müntehab-iSifa ", with today's physicians.

Ameliorative effect of selenium in cisplatin-induced testicular damage in rats.

In this study, we investigated the protective effect of selenium (Se) on cisplatin (Cis) induced testicular damage using histopathological, immunohistochemical and biochemical approaches. Twenty-one male Wistar rats were equally divided into three groups of seven rats each: control (C), Cis, and Cis+Se. Cis and Cis+Se group rats received Cis at a dose of 12mg/kg b.w./day, intraperitoneally for 3 consecutive days. Cis+Se group rats received selenium via oral gavage 3mg/kg/day (twice-a day as 1.5mg/kg) until 11th consecutive days starting at 5 days before cisplatin injection. C group received only 0.9% NaCl intraperitoneally and orally at same time and at equal volume. After the treatment, the histopathological, immunohistochemical and biochemical examinations were performed. In seminiferous tubules of Cis treated rats were observed the most consistent findings characterized with vacuolization, desquamation, disorganization, and also was a considerable reduction in elongated spermatids, however the Cis+Se group exhibited improved histopathologic changes. In the immunohistochemical examinations, caspase-3 immunopositive cells displayed higher in the Cis group according to C and Cis+Se groups. Bcl-2 and NF-κB staining revealed a moderate number in the C group and significantly fewer in the Cis group compared to the Cis+Se groups. Additionally, MDA levels were also significantly increased in the Cis group in comparison to Control group, but pretreatment with selenium prevented elevation of MDA levels significantly in Cis+Se group rats. This study indicates that Cis-treatment induced testicular apoptosis and lipid peroxidation, and combined treatment with selenium prevented severity of the toxicity in rats.

Melatonin protects kidney against apoptosis induced by acute unilateral ureteral obstruction in rats.

INTRODUCTION: To investigate whether there was a protective effect of melatonin on apoptotic mechanisms after an acute unilateral obstruction of the kidney. MATERIAL AND METHODS: A total of 25 rats consisting of five groups were used in the study, designated as follows: Group 1: control, Group 2: sham, Group 3: unilateral ureteral obstruction treated with only saline, Group 4: unilateral ureteral obstruction treated with melatonin immediately, and Group 5: unilateral obstruction treated with melatonin one day after obstruction. Melatonin was administered as a 10 mg/kg dose intraperitoneally. The kidneys were evaluated according to the apoptotic index and Ki-67 scores. RESULTS: Comparison of all obstruction groups (Group 3, 4, and 5), revealed that the apoptotic index was significantly higher in Groups 1 and 2. Despite melatonin reduced apoptotic mechanisms in Groups 4 and 5, there was no significant difference between Groups 4 and 5 in terms of the reduction of apoptosis. However, the reduction of apoptosis in the melatonin treated group did not decrease to the level of Groups 1 and 2. CONCLUSIONS: Despite melatonin administration, which significantly reduces the apoptotic index occurring after acute unilateral ureteral obstruction, the present study did not observe a return to normal renal histology in the obstruction groups.

Benign prostatic hyperplasia and prostate cancer differentiation via platelet to lymphocyte ratio.

BACKGROUND: The aim of the current study is to evaluate NLR and PLR inflammation markers in PCa and BPH. METHODS: Clinical and pathological data such as age, prostate volume, PSA, NLR, and PLR levels of 201 patients were retrospectively reviewed. Pathological sample results of these patients were categorized either as benign or malign. The benign group consisted of chronic prostatitis and BPH and the malign group of PCa. The PSA levels were divided into three categories as PSA: 0-4 ng/ml, PSA: 4-10 ng/ml, and 10 ng/ml and above. RESULTS: In the benign category, the mean PLR values for PSA: 0-4 ng/ml is 131.8 ± 31.2, for PSA: 4-10 ng/ml 124.7 ± 83.9 and 10 ng/ml and above 124 ± 53 in chronic prostatitis group and in the BPH group for PSA: 4-10 ng/ml 120.3 ± 45.1, for PSA: 4-10 ng/ml 126 ± 54.2, and 10 ng/ml and above 191.4 ± 176.1. In the malign category, the mean PLR values of PCa patients is for PSA: 0-4 ng/ml 122.8 ± 43.8, for PSA: 4-10 ng/ml 123 ± 43.8, and above 10 ng/ml 179.1 ± 94. Related to the variables of age, NLR, and mean prostate volume, there were no statistically significant differences. Statistically significant differences were observed in the mean PLR values only if the PSA level was 10 ng/ml and above (p: 0.044) in the BPH and PCa groups. The correlation of the PCa Gleason score and PSA, NLR and PLR parameters in the malign category revealed no statistically significant differences (P > 0.05). CONCLUSION: Effective malign and benign differentiation of prostate pathologies based on noninvasive inflammation biomarkers such NLR and PLR necessitate clinical studies with larger patient series.

What is harmful for male fertility: cell phone or the wireless Internet?

In this study, we aimed to assess the potential harmful effects of radiofrequency-electromagnetic radiation on sperm parameters. We requested semen for analyses from the male patients coming to our infertility division and also asked them to fill out an anonymous questionnaire. We queried their mobile phone and wireless Internet usage frequencies in order to determine their radiofrequency-electromagnetic radiation exposure. A total of 1082 patients filled the questionnaire but 51 of them were excluded from the study because of azoospermia. There was no significant difference between sperm counts and sperm morphology excluding sperm motility, due to mobile phone usage period, (p = 0.074, p = 0.909, and p = 0.05, respectively). The total motile sperm count and the progressive motile sperm count decreased due to the increase of internet usage (p = 0.032 and p = 0.033, respectively). In line with the total motile sperm count, progressive motile sperm count also decreased with wireless Internet usage compared with the wired Internet connection usage (p = 0.009 and p = 0.018, respectively). There was a negative correlation between wireless Internet usage duration and the total sperm count (r = -0.089, p = 0.039). We have also explored the negative effect of wireless Internet use on sperm motility according to our preliminary results.

The comparison of the influence between two different bowel preparation methods on sepsis after prostate biopsies.

INTRODUCTION: Transrectal ultrasonography (TRUS) guided prostate needle biopsy has been performed to diagnose and stage prostate cancer for many years. There are many different bowel preparation protocols to diminish the infectious complications, but there is no standardized consensus among urologists. Therefore, we aimed to assess two different bowel preparation methods on the rate of infectious complications in patients who underwent TRUS-guided prostate biopsy. MATERIAL AND METHODS: A total of 387 cases of TRUS-guided prostate biopsy were included in this retrospective study. All patients received antibiotic prophylaxis with ciprofloxacin (500 mg) twice a day orally for 7 days starting on the day before the biopsy. The patients were divided into two groups according to the bowel preparation method used. Patients (Group 1, n = 164) only received self-administrated phosphate enema) on the morning of the prostate biopsy. Other patients (Group 2, n = 223) received sennasoid a-b laxatives the night before the prostate biopsy. Infectious complications were classified as sepsis, fever (greater than 38°C) without sepsis, and other clinical infections. RESULTS: Major complications developed in 14 cases (3.8%), including 3 cases (0.8%) of urinary retention, and 11 (3%) infectious complications, all of which were sepsis. There were 3 and 8 cases of urosepsis in Group 1 and Group 2, respectively. There were no statistically significant differences between both Groups regarding to the rates of urosepsis (p = 0.358). CONCLUSIONS: Despite both methods of bowel preparation, sodium phosphate enema or sennasoid a-b calcium laxatives, before TRUS-guided prostate biopsy have similar effect on the rate of urosepsis, so both methods of bowel preparation can be safely used.

The association between serum follicle-stimulating hormone levels and the success of microdissection testicular sperm extraction in patients with azoospermia.

PURPOSE: To evaluate the predictive power of luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, testicular biopsy histology and male age were evaluated with respect to the success of sperm retrieval in a microdissection testicular sperm extraction (microTESE) procedure, pregnancy and live birth rates. MATERIALS AND METHODS: We examined the data of 131 infertile men with non-obstructive azoospermia, who have undergone microTESE operation. The men were classified into two groups based on serum follicle-stimulating hormone (FSH) levels ≤ 15 mIU/mL (group 1) and > 15 mIU/mL (group 2). RESULTS: Group 1 consisted of 59 patients (mean age 36.2 ± 6.2 years) and group 2 consisted of 72 (mean age 38.8 ± 7.4 years) patients. Sperm retrieval and pregnancy rates were 66.1% and 16.9% in normal FSH group, respectively. These parameters were higher than those of men with FSH > 15 (43% and 8.3%, respectively). Only 128 patients had histopathological diagnosis. Sperm was retrieved from 12/30 (40%) patients with maturation arrest, 9/29 (31.03%) patients with seminiferous tubules atrophy, 14/40 (35%) patients with sertoli cell only syndrome and 13/13 (100%) of patients with hypospermatogenesis. There was no statistically significant difference in pathological diagnosis between pregnancy and live birth rates. CONCLUSION: These results demonstrate that there is a significant difference with sperm retrieval, pregnancy rates and live birth rates comparing the FSH levels. Histopathological findings did not associate with successful microTESE, pregnancy rates and live birth rates.

Curcumin protects against ischemia/reperfusion injury in rat kidneys.

OBJECTIVES: Renal ischemia followed by reperfusion leads to acute renal failure in both native kidneys and renal allograft. We investigated the effect of curcumin on ischemia-reperfusion (I/R) injury and the antioxidant effects of curcumin in rats. METHODS: Thirty rats were randomly divided into five experimental groups (control, sham, curcumin, I/R and I/R+curcumin, n=6 each). Curcumin was administered (200 mg kg(-1)) orally to curcumin and I/R+curcumin groups for 7 days. Then, the rats were subjected to bilateral renal ischemia for 45 min and followed by reperfusion for 24 h. All rats were killed and kidney function tests, serum and tissue nitric oxide (NO), protein carbonyl (PC), malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) levels were determined. Histopathological examinations were also performed. RESULTS: Curcumin significantly improved the urea and cystatin C levels in I/R+curcumin group compared to I/R group (p<0.05). Reduction of serum GSH-Px was significantly improved by curcumin (p<0.001), but SOD enzyme activity did not alter (p>0.05). Treatment with curcumin also resulted in significant reduction in serum and tissue MDA, NO and PC and for tissue that were increased by renal I/R injury (p<0.001 for serum and p<0.05 for tissue, respectively). In histological examination, the rats treated with curcumin had nearly normal morphology of the kidney. CONCLUSIONS: Based on our results, it can be concluded that curcumin protects the kidneys against I/R injury via its antioxidant effects.
