Abstract
AIMS We aimed to evaluate the durability and cost effectiveness of the latest digital flexible ureterescope by comparing it with the conventional fiberoptic one. MATERIALS AND METHODS Data of patients who underwent retrograde intrarenal surgery between January 2013 and December 2014 were collected. Fiberoptic Flex-X2 or digital Cobra vision flexible ureteroscopes were used for the procedures. The comparison of both ureteroscopes was performed in terms of patient and stone characteristics, operative outcomes, durability, and cost effectiveness. RESULTS A total of 105 patients were evaluated for the study. The patient and stone characteristics and operative outcomes were similar between the groups. Overall, 54 and 51 procedures were performed using Flex-X2 and Cobra vision, respectively, before they were sent for renovation. The purchase prices were USD 29,500 for Flex-X2 and USD 58,000 for Cobra vision. Costs of per case were determined as USD 549.29 for Flex-X2 and as USD 1,137.25 for Cobra vision. Per minute working time costs were USD 772.04 and 1,471.33 for Flex-X2 and Cobra vision respectively. CONCLUSIONS The digital Cobra vision has high costs without any difference in durability as compared to Flex-X2. Moreover, it has no benefit over Flex-X2 in terms of surgical outcomes.

Abstract
BACKGROUND Renal ischemia-reperfusion (IR) leads to alterations of tubular epithelial cells, interstitial microvasculopathy and endothelial cell dysfunction in peritubular capillaries. Although dextrans have deteriorative effects on healthy kidney, their favorable effects on postischemic microvascular disturbances have been demonstrated. Therefore, we aimed to investigate in vivo effects of systemic dextran 70 administration in kidney tissue with ischemia-reperfusion injury. METHODS Twenty-one rats were allocated as sham, IR and IR+ dextran 70 treatment groups. Perirenal dissection without ischemia-reperfusion injury was performed with 0.9 NaCl solution infusions in the sham group. The left renal ischemia-reperfusion injury model was induced with % 0.9 NaCl and dextran 70 solutions infusion in the IR and IR+ dextran 70 treatment groups, respectively. At the end of the experimental procedures, histopathologic findings, serum creatinine and blood urea nitrogen levels, 24 hour urinary volumes, urinary albumin, KIM-1and IL-18 levels, and tissue MDA and SOD levels were compared between the groups. RESULTS We determined slightly reduction of the histopathologic structural changes and significant reduced levels of the albuminuria and KIM-1 in the IR +dextran 70 treatment group (P=0.03 and P=0.02, respectively). Higher 24 hour urine out put and free radical scavenger SOD levels were also detected with Dextran 70 treatment (P=0.0 and P=0.03, respectively). CONCLUSIONS Intravenous Dextran 70 infusion has some substantial protective effects against the ischemic injury of kidney.

Abstract
Objectives Smoking is the most important risk factor for bladder cancer and smoking cessation is associated with reduced risk of tumor recurrence and progression. The aim of this study is to assess the awareness of non-muscle invasive bladder cancer (NMIBC) patients regarding the importance of smoking cessation, determine their access to smoking cessation programs and the effects of smoking cessation on recurrence rates of NMIBC. Materials and Methods NMIBC patients who were followed with cystoscopy were included in the study. Their demographic properties were recorded, along with their smoking habits, awareness regarding the effects of smoking on bladder cancer and previous attempts for smoking cessation. Moreover, the patients were asked whether they applied for a smoking cessation program. Recurrence of bladder cancer during the follow-up period was also noted. Results A total of 187 patients were included in the study. The mean age was 64.68±12.05 (range: 15-90) and the male to female ratio was 167/20. At the time of diagnosis, 114 patients (61.0%) were active smokers, 35 patients (18.7%) were ex-smokers and 38 patients (20.3%) had never smoked before. After the diagnosis, 83.3% of the actively smoking patients were advised to quit smoking and 57.9% of them quit smoking. At the time of the study, 46.52% of the NMIBC patients were aware of the link between smoking and bladder cancer, whereas only 4.1% of the smoking patients were referred to smoking cessation programs. After a mean follow-up of 32.28±11.42 months, 84 patients (44.91%) had recurrence; however, current smoking status or awareness of the causative role of smoking on NMIBC did not affect the recurrence. Conclusion In our study group, the majority of the NMIBC patients were not aware of the association between smoking and bladder cancer. Although most of the physicians advised patients to quit smoking, a significant amount of the patients were still active smokers during follow-up. Only a small proportion of patients were referred to smoking cessation programs. Urologists should take a more active role in the battle against smoking and refer those patients to smoking cessation programs. Larger study populations with longer follow-up periods are needed to better demonstrate the beneficial effects of smoking cessation on recurrence rates.

Abstract
OBJECTIVE To investigate the efficacy and safety of retrograde intrarenal surgery (RIRS) in the treatment of pediatric cystine stones. STUDY DESIGN Data of the pediatric patients who underwent RIRS for kidney stones were retrospectively evaluated. A total of 14 children with cystine stones managed with RIRS were identified. In addition to the patient demographics and stone characteristics, all retrospectively obtained operative data were evaluated and discussed in detail, with an emphasis on the success and complication rates. RESULTS Mean age of the 14 cases was 10.9 ± 2.2 years (range: 7-15). Mean stone size was 13.6 ± 2.4 mm (range: 10-18) (Summary table). Of these stones, four were located in the renal pelvis, three were in the lower, three were in the middle and the remaining four were located in upper calyx. Ureteral access sheath was used in 12 (85.7%) patients. The double-J ureteral stent was placed pre-operatively in one case and was inserted postoperatively in 12 cases. Mean operation time was 38.2 ± 7.2 min (range: 30-50). Complications were observed in two cases: mild ureteral laceration in the first and fever on the second postoperative day in the second patient. All of the patients were stone free on sonographic evaluation at the 4-week follow-up evaluation. Although potassium citrate treatment was initiated in 11 patients, tiopronin treatment was initiated in four patients for recurrence prophylaxis during long-term follow-up. During a mean follow-up period of 25.7 ± 5.2 months, stone recurrence was noted in one patient. DISCUSSION Treatment of patients with cystine stones is challenging, due to high risk of rapid recurrence in the presence of residual fragments. Besides allowing complete stone clearance in all cases in the current series, RIRS is a highly reproducible method that can be safely performed, even in recurrences. The major limitations of the current study were low number of patients and short follow-up period. CONCLUSION The results clearly indicated that RIRS is a safe treatment modality in the management of pediatric cystine stones.

Abstract
OBJECTIVES The aim of this study is to evaluate the effects of the herbal agent in the prevention and treatment of bacterial cystitis in a rat model. MATERIAL AND METHODS A total of twenty-eight male Sprague- Dawley rats were divided into four groups. Group-1 constituted the control group (operated and normal saline injected into the bladder, received only drinking water for 7 days); Group-2 constituted the no-treatment group (operated, E.coli J96 strain injected into the bladder, received only drinking water for 7 days); Group-3 constituted the short-term treatment (operated, E.coli J96 strain injected into the bladder, received the herbal agent added into drinking water for 7 days) and Group-4 constituted the long-term treatment (operated, E. coli J96 strain injected into the bladder, received herbal agent added into drinking water for 14 days). At the end of the pre-defined treatment periods of duration, the rats were sacrificed, urine samples collected from the bladder for culture and bladders were harvested for histopathological evaluation. Urine culture results and histopathological findings were comparatively evaluated between the groups. RESULTS Urine cultures were positive for implanted E. coli strains in 0%, 85.7%, 42.8% and 0% of rats in Group 1, Group 2, Group 3 and Group 4, respectively (p = 0.001). Although histopathological evaluation revealed increased vascular dilation in the bladder specimens obtained from Group 2 and Group 3 (p = 0.028) no significant difference was noticed in level of inflammation (p = 0.610), edema (p = 0.754) and thickness of uroepithelium (p = 0.138). CONCLUSION While long term (14 days) treatment with an herbal agent added into the drinking water resulted in complete clearance of urine from E. coli; shorter application of the agent revealed partial clearance. Further clinical studies are needed to support our results.

Abstract
Introduction The aim of this study was to demonstrate the efficacy of Instadose™, a novel dosimeter designed for radiation workers to provide a measurement of the radiation dose at any time from any computer; to determine the amount of radiation exposure during percutaneous nephrolithotomy (PNL); and to evaluate the factors that affect the amount of radiation exposed. Material and methods Two experienced surgeons wore Instadose™ on the outer part of their lead aprons during the PNL procedures performed between December 2013 and July 2014. Patient demographics and stone characteristics were noted. Factors affecting radiation dose were determined. Fluoroscopic screening time was compared with the amount of radiation in order to validate the measurements of Instadose™. Results Overall, 51 patients with a mean age of 43.41 ±18.58 (range 1–75) years were enrolled. Male to female ratio was 35/16. The amount of radiation was greater than 0.01mSv in only 19 (37.25%) cases. Stone location complexity (p = 0.380), dilation type (p = 0.584), stone size (p = 0.565), dilation size (p = 0.891) and access number (p = 0.268) were not associated with increased radiation exposure. Instadose™ measurements were correlated with fluoroscopic screening time (r = 0.519, p = 0.001). Conclusions Instadose™ is a useful tool for the measurement of radiation exposure during PNL. The advantage of measuring the amount of radiation exposure after each PNL operation is that it may aid urologists in taking appropriate precautions to minimize the risk of radiation related complications.

Abstract
PURPOSE To determine the diagnostic value of computerized tomography (CT) in differentiating pyonephrosis from hydronephrosis on the basis of attenuation values (Hounsfield unit-HU). METHODS Data of the patients with grades 1-3 hydronephrosis on abdominopelvic CT, who underwent nephrostomy tube placement for decompression of the collecting system, were retrospectively analyzed. Patient demographics and CT findings were recorded along with the first access urine culture results. Three physicians calculated the surface areas and the attenuation values of the dilated collecting systems using the system software. Mean HU of pyonephrosis and hydronephrosis cases was compared. RESULTS A total of 105 patients with the mean age of 47.7 ± 15.5 (range 20-80) were included. The interclass correlation coefficient of three physicians was 0.981 for HU measurement and 0.999 for calculation of collecting system surface area. Of the patients, 47 (44.8 %) had pyonephrosis. Mean surface areas of the collecting system were similar in patients with pyonephrosis and hydronephrosis (1481.13 ± 1562.94 vs. 1612.94 ± 2261.4 mm2, p = 0.735). Urine cultures were positive in all patients with pyonephrosis, whereas 12.7 % of hydronephrosis cases had bacterial in first access urine culture. The HU of the patients with pyonephrosis was significantly higher that that of patients with hydronephrosis (13.51 ± 13.29 vs. 4.67 ± 5.37, p = 0.0001). Having a HU of 9.21 or over diagnosed pyonephrosis accurately with 65.96 % sensitivity and 87.93 % specificity. CONCLUSION Measuring attenuation values of the collecting system may be useful to differentiate pyonephrosis from hydronephrosis. Diagnosing pyonephrosis accurately may avoid septic complications.

Abstract
The purpose of this study was to determine differences in genotype distribution and allele frequency of urokinase and vitamin D receptor (VDR) single nucleotide polymorphisms (SNPs) between first-stone formers, recurrent stone formers, and controls in a Caucasian population. A total of 86 first-stone formers, 78 recurrent stone formers, and 167 controls were included. Urokinase and VDR SNPs were tested by gene amplification followed by ApaL1 and Taq1 endonuclease digestion, respectively. Baseline variables, genotype, and allele frequencies were compared between the three groups, using descriptive statistics. Adjusted odds ratios were calculated to estimate the risk for recurrent urolithiasis associated with genotypes. We found that differences in the distribution of ApaL1 SNP and Taq1 SNP genotypes were statistically different between recurrent stone formers and first-stone formers, and between recurrent stone formers and controls. Allele frequency analysis showed that the T allele for ApaL1 SNP and the C allele for Taq1 SNP were significantly associated with recurrent urolithiasis. For Taq1 SNP, logistic regression analysis showed that the C/C genotype was associated with a more than threefold higher risk for recurrent urolithiasis. We conclude that ApaL1 and Taq1 SNPs of the urokinase and VDR genes are associated with recurrent urolithiasis in a Caucasian population.

Abstract
Several types of suture materials are being used for the correction of penile curvature and this study was designed to compare histopathological changes on penile tissue among different suture materials. A total of 30 male Sprague-Dawley rats were divided into five groups and right cavernosal body was sutured with 5/0 sutures (ETB: polyethylene terephthalate; PRL: polypropylene; VCR: polyglactine; and PDS: polydioxanone). An identical needle (3/8-13 mm cutting) was passed through the cavernosal bodies in the sham group (SHAM). After 3 weeks, all rats were killed and penile tissues were examined to assess the level (0-3) of inflammation, granuloma formation and fibrosis. There was a statistically significant difference among five groups regarding inflammation, granuloma formation and fibrosis levels (P<0.01 for all). The histological changes in the PRL group were not different from the SHAM group. Although the levels of granulation and fibrosis in the PDS group were also similar to the SHAM group, inflammation level was significantly higher. The inflammation, granulation and fibrosis levels were the highest in the ETB group. VCR caused similar levels of granulation and fibrosis to ETB. In conclusion, PRL suture is associated with the least histopathological change in the penile tissue. PDS can theoretically be a reasonable alternative to PRL as it causes similar levels of granulation and fibrosis.

Abstract
Fournier's Gangrene (FG) is a type of necrotizing infection or gangrene usually affecting the perineum. Penile gangrene is a rare disease because of rich collateral circulation and blood flow in the perineum and lower abdomen. We report an unusual and rare presentation of FG with isolated glans penis necrosis in a 62-year-old man. The patient underwent subtotal penectomy and closure of the wound with penile skin flap after covering the spongious tissue with dartos fascial flap enclosing the urethra. The recovery phase was uneventful and the patient had no urinating symptoms during follow-up.

Abstract
Bladder cancer is the most common malignancy of urinary tract and the seventh most common cancer in men with the peak incidence in the sixth decade of life. Our knowledge about bladder tumors in pediatric age group mainly relies on case series. The reported cases are mostly low grade and non-muscle invasive. We herein present a case of a 17-year-old male with metastatic high-grade muscle-invasive bladder cancer who was presented with macroscopic hematuria and flank pain.

Abstract
PURPOSE Studies about the anesthesia techniques during transrectal ultrasound guided prostate biopsy (TRUS-Bx) are usually focused on pain relief. Although patients' tolerance is an important issue in TRUS-Bx, cancer detection rate (CDR) must not be ignored. In this study, we compared the impact of intrarectal lidocaine gel anesthesia (IRLA) and periprostatic nerve blockade (PNB) techniques on CDR. MATERIALS AND METHODS A total of 422 patients underwent 10 core-TRUS-Bx because of elevated serum prostate specific antigen (PSA) level (>2.5ng/mL) and/or suspicious digital rectal examination findings. Patients were divided into two groups according to the applied anesthesia technique: IRLA group and PNB group. Age, serum PSA level, prostate volume, visual analogue scale (VAS) score and CDR were recorded and compared statistically with chi square and unpaired t-tests. RESULTS Of the patients 126/422 (29.9%) underwent TRUS-Bx by using IRLA whereas 296/422 (70.1 %) by PNB technique. The mean, age, serum PSA level and prostate volume were similar between the two groups. CDR was 19.8% and 25.4% in IRLA and PNB groups, respectively (p=0.001). The mean VAS score of the PNB group (1.84±0.89) was significantly lower than that for IRLA group (3.62±1.06) (p=0.001). CONCLUSIONS Our results revealed that PNB is superior to IRLA in terms of CDR. Further studies are required to confirm our findings.

Abstract
Inflammatory myofibroblastic tumour (IMT) is a rare benign mesenchymal tumour. However, IMT may arise from a wide variety of tissues and is very rare in the elderly. IMT may mimic the mass in which it originates. Although IMT has been defined as uncertain behaviour, it is treated surgically. We present a-65-year old man whose mass was diagnosed as IMT extending from scrotum to pelvis. The mass was independent of any surrounding anatomic structures. According to our best knowledge this is the first case in the literature that pelvic IMT was diagnosed in an elderly man and successfully treated surgically with a long term follow-up period. Aetiology of IMT is still unknown, and more studies are needed for exact continuum of IMT.

Abstract
OBJECTIVE To investigate the effect of human chorionic gonadotrophin (hCG) on rat testicular tissue, and its reversibility and dose dependence. MATERIALS AND METHODS Male Wistar rats were assigned to groups (10 rats/group) receiving 10, 30 or 50 IU/kg hCG subcutaneously once daily for 15 days; 10 controls received subcutaneous isotonic saline. At 1 and 3 months later, five rats in each group were killed and their testes removed. The testes were examined histologically to measure seminiferous tubular diameter and germinal membrane thickness. RESULTS At 1 month after hCG administration, the mean germinal membrane thickness in the testicular tissues of the hCG-treated rats was significantly less than in control rats, and was also significantly different between all of the hCG-treated groups (P < 0.05). However, at 3 months after hCG administration, all histological variables were similar to those in control rats (P > 0.05), and the mean germinal membrane thickness at 3 months after hCG administration was larger than that at 1 month (P < 0.05). There were no significant differences in the mean seminiferous tubular diameter between hCG-treated rats and control rats. CONCLUSION hCG impairs seminiferous tubule histology in the 'normal' descended testes of rats. This effect was dose-dependent, and the changes were reversed at 3 months after treatment. Thus, although hCG therapy might affect the seminiferous tubules of contralateral descended testes in cryptorchid boys, these effects might be reversible.
