Abstract
INTRODUCTION Human papillomavirus infection (HPV) is one of the most common sexually transmitted infections and can cause penile and anal cancer in men, and invasive cervical cancer in women. OBJECTIVE To evaulate the colonization of 32 HPV subtypes in the foreskin of boys. STUDY DESIGN A prospective analysis was made of the data of 62 healthy boys who had undergone standard circumcision. Deoxyribonucleic acid (DNA) was isolated from the foreskin tissues, and the integrity of DNA was tested. The DNA of each patient was further assessed with real-time polymerase chain reaction (PCR) and the presence of 32 subtypes of HPV was explored. To confirm the results, melting curve analysis and agarose gel electrophoresis (AGE) were performed for all samples. Further analysis was made using LCD-array on six randomly selected samples to confirm the results together with negative and positive controls. RESULTS The mean age of the boys was 6.8 ± 2 years at the time of surgery. All positive controls and samples were positive, all negative controls were negative in the first HPV amplification assay. All positive controls had typical melting curve peaks, whereas all sample amplifications had non-specific, atypical melting curves not fitting with those of the positive controls. Two bands of expected sizes (124 and 405 bp) were only observed in positive controls, but not in negative controls or samples on AGE. The same results were observed on the 6 randomly selected samples using LCD-array. Consequently, all the foreskin samples were evaluated as negative for the 32 HPV types investigated in the study. DISCUSSION Literature shows a high prevalence of genital HPV in newborns, in early infancy, late adolescence and adulthood. However there is a lack of data in literature on the prevalence in early and late childhood. The negative results of HPV colonization on the foreskin in the current study may be attributed to the conservative and mostly monogamous nature of most family structures in Turkey. CONCLUSION The results of the present study have shown that foreskin tissue is not a natural reservoir for HPV and subclinical HPV infection is not likely in the absence of suspected sexual contact.

Abstract
One of the most important causes of varicocele-related infertility is oxidative stress (OS). One of the markers considered as an indicator of OS is thiol-disulphide homeostasis (TDH). Based on the hypothesis that OS should decrease after varicocelectomy in the light of this information, in our current study, we investigated the relationship between TDH levels and sperm parameters. The data of 56 infertile varicocele men were prospectively analysed. The post-operative total and native thiol levels were significantly higher than those pre-operative total and native thiol levels (477.7 & 436.7 nmol/L, 417.6 & 372.1 nmol/L). Positive correlation was found between total thiol change and change in semen volume (ρ: .277, p: .039), ratio of spermatozoa with normal morphology (ρ: .342, p: .01), progressive (ρ: .334, p: .012) and nonprogressive motility (ρ: .385, p: .003). Positive correlation was also found between native thiol change and semen volume (ρ: .349, p: .008), ratio of spermatozoa with normal morphology (ρ: .362, p: .006), progressive (ρ: .297, p: .026) and nonprogressive motility (ρ: .368, p: .005). Change in the level of TDH was found as positively correlated with progressive and nonprogressive motility change. According to these results, OS decreases with varicocelectomy in infertile patients and TDH can be used as a useful method for measuring OS.

Abstract
PURPOSE We analyzed the role of oxidative stress in detrusor overactivity (DO) by measuring serum total antioxidant capacity (TAC), total oxidant status (TOS), binding capacity of exogenous cobalt to human albumin (IMA), serum advanced oxidation protein products (AOPP), paraoxonase (PON), and arylesterase. MATERIALS AND METHODS The study included 38 female patients diagnosed with DO and 29 healthy female subjects forming the control group. Serum total antioxidant capacity (TAC), total oxidant status (TOS), binding capacity of exogenous cobalt to human albumin (IMA), serum advanced oxidation protein products (AOPP), paraoxonase (PON), and arylesterase were analyzed. The results of serum TAC, TOS, IMA, AOPP, PON, and arylesterase of the subjects in both groups were compared. RESULTS There was no difference between the groups in terms of age. When compared to the control group, serum TAC and IMA levels were statisticaly lower (P < 0,001) and higher (P = 0,003), respectively. However, TOS, AOPP, PON, arylesterase levels were similar in both groups ( p > 0.05 ). CONCLUSION There seems to be an association between DO and oxidative damage according to our results, this can be measured by analyzing TAC and IMA in this patient group.

Abstract
OBJECTIVE We evaluated the effect of diabetes mellitus (DM) on urinary continence after robotic radical prostatectomy (RARP). PATIENTS AND METHODS Overall, 99 patients with DM and 213 patients without DM who underwent RARP with at least 2-year follow-up were included. The preoperative prostate biopsy Gleason scores and clinical stages of the groups were similar. The patients who were dry or used one safety pad per day were regarded as continent. Early (0-3 months), mid-term (4-12 months), and late-term (>12 months) continence rates were evaluated. RESULTS In diabetic and nondiabetic groups, mean age was 63.3 ± 6.5 and 61.3 ± 6.8 years, respectively (p = 0.015). On the day of the removal of the urethral catheter, 61.6% (n = 61) of the diabetic patients and 99.1% (n = 211) of the nondiabetic patients were continent (p = 0.000). At third-month follow-up, 80.8% (n = 80) of the diabetic patients and 99.1% (n = 211) of the nondiabetic patients were continent (p = 0.000). At sixth-month follow-up, 89.9% (n = 89) of the diabetic patients and 99.1% (n = 211) of the nondiabetic patients were continent (p = 0.000). At first-year follow-up, 93.9% (n = 93) of the diabetic patients and 100% (n = 213) of the nondiabetic patients were continent (p = 0.001). At 18th-month follow-up, 96.0% (n = 95) of the diabetic patients and 100% (n = 213) of the nondiabetic patients were continent (p = 0.013). At second-year follow-up, 98.0% (n = 97) of the diabetic patients and 100% (n = 213) of the nondiabetic patients were continent (p = 0.115). Multivariate analysis showed that age and body mass index had no impact on urinary continence (p > 0.05). Presence of diabetes (p = 0.008) and duration (≥5 years) of diabetes (p = 0.004) were independent factors that had a significant negative impact on urinary continence. CONCLUSIONS Diabetes seems to be a significant disadvantage in gaining urinary continence compared with nondiabetic patients particularly in the first 18 months after RARP. Diabetic patients should be informed about possible late recovery of postoperative urinary continence compared with nondiabetic patients after RARP.

Abstract
PURPOSE The mean platelet volume (MPV) has important role in the pathophysiology of vascular diseases as a marker of the platelet activity. To investigate the association between mean platelet volume and erectile dysfunction (ED) and to search whether this marker can be used for diagnosis of ED. MATERIALS AND METHODS Of the 312 patients with ED of various degrees, 122 patients without ED (IIEF-5>21) were included in this prospective study. Severity of ED was determined according to IIEF-5 questionnaire. MPV, fasting serum glucose, cholesterol, low density lipoprotein (LDL) and serum testosterone levels are also recorded. The mean platelet volume was calculated by the Coulter counter technique and sexual function was determined by International Index of Erectile Function erectile function domain (IIEF-5). RESULTS The mean age of patients was 58.4 years. The mean MPV value of patients with ED was significantly higher compared to the non-ED patients (8.91 vs. 8.22, p=0.0001). The severity of ED was shown to have a positive strong correlation with MPV values (r=0.719, p=0.001). Mean serum triglyceride, glucose, total cholesterol and LDL cholesterol levels were noted higher in patients with ED. MPV values were found to be significantly higher in patients with ED. CONCLUSION MPV level shows significant correlation with severity of ED. This cheap laboratory test can have potential to be a marker of ED. Further prospective larger studies with vascular wall thickness measurements should be conducted.

Abstract
Introduction Urinary stone disease is a major urological condition. Endourologic techniques have influenced the clinical approach and outcomes. Open surgery holds a historic importance in the management of most conditions. However, complex kidney stone burden may be amenable to successful results with open stone surgery. In this article, we report our eighteen cases of complex urinary stone disease who underwent open stone removal. Material and methods A total of 1701 patients have undergone surgical treatment for urinary stone disease in our clinic between July 2012 and July 2016, comprising eighteen patients who underwent open stone surgery. Patients’ demographic data, stone analysis results, postoperative clinical data, and stone status were evaluated retrospectively. The choice of surgical approach is mostly dependent on the surgeon’s preference. In two patients, open surgery was undertaken because of perioperative complications. Results We did not observe any Clavien-Dindo grade 4 or 5 complications. Three patients were managed with a course of antibiotics due to postoperative fever. One patient had postoperative pleurisy, one patient had urinoma, and two patients had postoperative ileus. Mean operation time was 84 (57–124) minutes and mean hospitalization time was 5.5 (3–8) days. Stone-free status was achieved in 15 patients (83.3%). Conclusions Endourologic approaches are the first options for treatment of urinary stone disease. However, open stone surgery holds its indispensable position in complicated cases and in complex stone burden. Open stone surgery is also a valid alternative to endourologic techniques in all situations.

Abstract
The aim of this study was to investigate the protective effects of trimetazidine (TMZ), as an antioxidant agent, on streptozotocin (STZ)-induced diabetic rats. A total of 50 male Sprague Dawley rats were randomly classified into five groups as follows: Group 1 (control), Group 2 (STZ-induced diabetic rats), Group 3 (STZ-induced diabetic rats treated orally with 1 cc/day isotonic saline), Group 4 (diabetic rats treated orally with 10 mg/kg/day TMZ) and Group 5 (diabetic rats treated orally with 20 mg/kg/day TMZ). After 8 weeks, orchiectomy was carried out. Histopathological and electron microscopic examinations were performed in all groups. In groups 1 and 5, the structural and ultra-structural findings of the testicular tissue and spermatogenesis were found normal. In groups 2, 3 and 4, similar results were obtained in terms of the impaired testicular architecture and degeneration of spermatogenesis. The administration of an optimal dose of TMZ protects against the harmful effects of diabetes mellitus on spermatogenesis in rats. TMZ therapy can be used to maintain normal spermatogenesis in diabetic rats.

Abstract
OBJECTIVE In this study we aimed to compare renal functions in patients who underwent robotic partial nephrectomy (RPN) with on-clamp and zero- ischemia techniques. MATERIAL AND METHODS Between 2009 and 2015, 12 off-clamp and 22 on-clamp RPN procedures were performed on a total of 34 patients in two centers. The main outcome parameters examined were serum creatinine, and estimated glomerular filtration rate (eGFR) during preoperative, immediate postoperative periods, and at postoperative 3rd months. RESULTS There were no statistically significant differences between on-clamp and zero- ischemia groups regarding age, ASA score, BMI, PADUA and R.E.N.A.L. nephrometry scores, operation time and tumor size (p>0.05). Significant differences were found in the duration of hospital stay (3.8±0.9 days vs. 3.0±0.9 days) and amount of blood loss (85.9±49.6 mL vs. 183.3±176.2 mL) between the on-clamp and zero-ischemia groups (p<0.05). Statistically significant differences were found between preoperative and immediate post-operative periods, in terms of eGFR and serum creatinine levels in both groups. Moreover, statistically significant differences were found between preoperative and postoperative 3rd month periods, in the on-clamp group in terms of eGFR and serum creatinine levels. In the zero-ischemia group, the decrease in eGFR and serum creatinine levels at postoperative 3rd month relative to the preoperative period was not statistically significant. CONCLUSION Off-clamp RPN technique is superior, in short-term outcomes involving renal functions, compared to on clamp approach. However, long- term data regarding the renal functions should be evaluated to arrive at a definitive decision.

Abstract
PURPOSE To examine the effect of steep Trendelenburg position (ST) on intraocular pressure (IOP), resistive index of the central retinal artery, and venous impedance index of the central retinal vein during robotic prostatectomy and cystectomy. METHODS A total of fifty-three male patients were included into the study (prostatectomy: 43, cystectomy: 10). During robotic surgery, the effect of the ST on IOP, resistive index of the central retinal artery (CRA-RI), and venous impedance index of the central retinal vein (CRV-VI) was prospectively examined. The measurement times of IOP are as follows: T1: before anesthesia while supine and awake; T2: anesthetized and supine; T3: anesthetized and ST; T4: anesthetized, ST, and intraperitoneal insufflation; T5: anesthetized in ST at the end of the procedure with CO2; T6: anesthetized in ST after desufflation; and T7: anesthetized supine before awakening. RESULTS There was no difference between the IOP values of the right and left eyes in both groups. The highest IOP values were reached at T4 and T5. CRA-RI values were different, while CRV-VI values were similar at T1 and T4. CONCLUSIONS Despite staying in the ST for a long time provided that the ophthalmologic examination was normal, ocular complication risk is low in robotic prostatectomy and cystectomy.

Abstract
The aim of this study was to evaluate outcomes of robotic partial nephrectomy (RAPN) procedures. At two centers, 42 patients underwent RAPN. Radius, Exo/Endophytic, Nearness, Anterior/Posterior, Location (R.E.N.A.L.) nephrometry and PADUA scores of patients were calculated by computed tomography (CT) or magnetic resonance imaging (MRI). Intra- and perioperative (0-30 days) complications were evaluated using modified Clavien classification. A four-arm da Vinci-S robotic surgical system was used and outcomes were evaluated retrospectively. Mean age of the patients was 52.3 ± 6.5 years. Mean tumor size was 3.1 ± 1.0 (1.4-6.6) cm. R.E.N.A.L. nephrometry and PADUA scores were 6.0 ± 1.5 and 7.5 ± 0.9, respectively. Mean surgical time was 127.7 ± 18.7 minutes and estimated blood loss was 100 ± 18.1 cc. Mean warm ischemia time was 16.0 ± 8.9 (0-30) minutes. Intraoperative complications did not develop in any patient. Median hospital stay was 3.0 (2-6) days. Except for 17 patients, hilar clamping was performed in 25 patients. Histopathology results included 34 renal cell carcinoma (22 clear cell, 7 chromophobe cell, 4 papillary cell, and 1 clear papillary cell). Oncocytoma (n = 4), adenoma (n = 1), fibroadipose tissue (n = 1), papillary epithelial hyperplasia (n = 1), and chronic pyelonephritis (n = 1) were present. Surgical margins were negative in all patients. During a median follow-up period of 15.5 ± 10.9 (3-46) months, neither local recurrence nor distant metastasis was detected. In conclusion, RAPN is a safe, minimally invasive surgical approach, with excellent surgical and oncological outcomes in T1 kidney tumors. Zero ischemia off-clamp RAPN is also safe in selected masses with the advantage of avoiding complete renal ischemia.

Abstract
Introduction We evaluated and compared the serum oxidative stress and antioxidant enzymes in patients with renal cell carcinoma (RCC) and the control group. Material and methods The prospective study consisted of 97 patients with RCC (Group 1) and 80 age and sex matched healthy volunteers (Group 2). Group 1 and 2 were compared concerning serum mean total oxidant status (TOS), total antioxidant capacity (TAC), paraoxonase-1 (PON-1), arylesterase, total thiol, catalase (CAT), myeloperoxidase (MPO) and ceruloplasmin. Results Patients’ mean age was 58.5 ±12.3 and 56.9 ±15.8 years, respectively, in Group 1 and 2. No statistically significant differences were detected between the groups in terms of oxidative stress parameters and antioxidant capacity measured in the serum of patients including, TOS, TAC, PON1, arylesterase, total thiol, CAT, MPO, and ceruloplasmin levels (p >0.05 for all parameters). The PON-1 value was significantly higher in patients with pT1 stage than pT3 stage (p = 0.007). The arylesterase value was significantly higher in patients with Fuhrman's nuclear grade 3 than grade 2 (p = 0.035). There was no correlation between these parameters level and Fuhrman's nuclear grade, stage, or histopathological tumor type. Conclusions Our results demonstrated that evaluation of these parameters in the serum of patients with localized RCC may not be used as a marker to discriminate between patients with RCC and healthy people.

Abstract
Currently, most renal masses are detected incidentally while still small in size because of the widespread use of radiological imaging, and most pheochromocytomas are localized in the adrenal glands as unilateral lesions. A 5 × 4-cm right adrenal mass and a 19 × 13-mm exophytic left renal mass were synchronously detected by contrast enhancement on computed tomography and magnetic resonance imaging in a 47-year-old male with hypertension. The patient's preoperative serum and 24-h urine catecholamine levels were elevated. Initially, robotic transperitoneal right adrenalectomy was performed, and histopathology confirmed a 4 cm pheochromocytoma. After 3 months, transperitoneal zero ischemia robotic left partial nephrectomy was performed, and histopathology demonstrated clear cell renal cell carcinoma, Fuhrman grade II, 17 mm in size with clear surgical margins. This case indicates that sequential robotic surgery is feasible and safe as a minimally invasive approach to remove bilateral renal and adrenal masses. Zero ischemia robotic partial nephrectomy is also feasible and safe for selected small renal masses.

Abstract
OBJECTIVE We evaluated outcomes of our robot-assisted laparoscopic transperitoneal pyeloplasty (RALP) procedures. MATERIAL AND METHODS Between July 2011 and March 2014, 18 RALP procedures were performed at our instutition. Ureteropelvic junction obstruction (UPJO) diagnosis was made based on clinical presentation and intravenous urography. All patients underwent basal and diuretic isotopic renography to evaluate the degree of obstruction and impaired renal function. Anderson-Hynes dismembered pyeloplasty technique was used with a transperitoneal approach by using the da Vinci-S 4-arm surgical robot. Outcomes were assessed retrospectively. RESULTS Mean patient age was 31.3±11.7 (13-62) years. Male: female ratio was 9: 9. All procedures were primary surgeries. Of 18 patients, 10 (55.5%) had a crossing vessel and 8 (44.5%) had intrinsic obstruction. Mean operative time was 150.4±17.2 (115-185) minutes. Mean anastomosis time was 21.4±5.5 (10-33) minutes. Mean blood loss during the operation was 33.6±17.3 (10-60) cc. Mean hospital stay was 2.6±1.0 (1-6) days. No conversion to open surgery was required. No intraoperative and perioperative (0-30 days) complication occurred. Readmission rate during perioperative period was 0%. Median follow-up was 16.6±10.3 (3-35) months. Postoperative intravenous urography and renography showed improved results in all cases. CONCLUSION Due to our experience, RALP is a safe and feasible minimally invasive approach in patients with UPJO with excellent surgical and functional outcomes.

Abstract
In this study, we aimed to investigate the effects of ureterorenoscopy (URS) on morbidity and renal functions in patients with ureteral stones and nondialysis-requiring renal insufficiency. The data of 3200 patients who had ureterorenoscopic lithotripsy and diagnostic URS were analyzed retrospectively. Age, urea and creatinine levels in the preoperative period and 4 h after surgery, the size of the stone, duration of surgery, percentage change in urea and creatinine levels [(last level-first level/first level) × 100] and postoperative complications were noted. Student's t-test was used for the intergroup analysis of continuous variables. p < 0.05 was considered as statistically significant. There were 90 patients in nondialysis-requiring renal insufficiency group (group 1) and 101 patients in the control group (group 2). Percentage changes of urea and creatinine levels in the renal insufficiency and the control groups were found as -0.3% ± 3.3, 0.67% ± 3.9 and 2.3% ± 23.2, 2.5% ± 31.6 (p = 0.24 and p = 0.56), respectively. In group 1, three (3.3%) patients had postoperative febrile urinary infection, however febrile infections were not seen in any of the patients in group 2 (p = 0.06). Our results indicated that URS might be used safely in ureteral stones of the patients with nondialysis-requiring renal insufficiency.

Abstract
Teratomas are bizarre neoplasms derived from embryonic tissues that are typically found only in the gonadal and sacrococcygeal regions of adults. Primary retroperitoneal teratomas are rare and present challenging management options. We report a case of a unilateral primary retroperitoneal mature cystic teratoma mimicking an adrenal mass in a 54-year-old male patient. Complete resection of the adrenal mass was performed by the flank approach by using the 11th rib resection. Because of the risk of malignancy, follow-up radiographic studies were performed to ensure the oncologic efficacy of resection. The patient has been free of recurrence for longer than 12 months.

Abstract
UNLABELLED In this study, we investigated whether electromyography of corpus cavernosum (CC-EMG) results vary with age and whether CC-EMG could be a parameter to predict ageing of cavernous smooth muscle. Recordings of electrical activity of corpus cavernosum (EACC) were retrospectively investigated in 134 patients with erectile dysfunction. Penile colour Doppler ultrasonography and cavernosometry were also performed for all of the patients. The total number and duration of EACC and amplitudes between positive and negative peaks were compared between the flask state for 10 min and after intracavernosal papaverine injection. The mean age of the 47 patients in group 1 was 35.2 ± 6.3 years (range, 23-44), the mean age of the 45 patients in group 2 was 51.1 ± 3.1 years (range, 45-56) and the mean age of the 42 patients in group 3 was 61.8 ± 4.6 years (range, 57-77). Total IIEF-5 score was 7.6 ± 2.1 in group 1, 7.9 ± 2.4 in group 2 and 7.9 ± 2.1 in group 3. There were no statistically significant differences among the groups regarding electrical potential frequencies, durations and amplitudes of electromyographic recordings. CONCLUSION We do not think that CC-EMG findings could be used efficiently as a predictor of ageing.

Abstract
UNLABELLED OBJECTIVE. To evaluate the effects of short term use of dutasteride and Serenoarepens before transurethral resection of the prostate (TURP) on the amount of intraoperative blood loss and microvessel density (MVD) of prostatic stromal and suburethral tissues in the patients with benign prostatic hyperplasia. PATIENTS AND METHODS The study involved 75 male patients who planned to have a TURP. The patients were randomly divided into three groups. The control group comprised 21 patients. Group 2 comprised 27 patients who used dutasteride 5 mg/day, and group 3 comprised 27 patients who used S. repens 160 mg/day for 5 weeks before the operation. The amount of intraoperative haemorrhage was calculated. Total blood loss, total blood loss/time, total blood loss/weight of resected tissue and total blood loss/weight/time were calculated for each patient and all were recorded. Sections from the prostatic stromal and suburethral tissues were examined for suburethral and prostatic MVD. RESULTS The total amount of intraoperative blood loss, total blood loss/time, total blood loss/weight of resected tissue, total blood loss/weight/time, serum haemoglobin level change, prostatic MVD and suburethral MVD of the groups were compared. No significant statistical differences were found between the groups for any of these variables (p > 0.05). CONCLUSIONS Dutasteride and S. repens therapies were not superior to control in terms of the decrease in total blood loss during TURP. Moreover, MVD showed no statistical differences in the treatment groups compared with the control group.

Abstract
PURPOSE To evaluate the efficacy of sildenafil citrate only, 25 mg. Four times/week, tamsulosin only, 0.4 mg once daily, and the combination of both on lower urinary tract symptoms (LUTS) suggestive of benign prostate hyperplasia (BPH) and erectile dysfunction. METHODS A total of 60 men with BPH-related LUTS were randomized to receive sildenafil citrate only (n = 20), tamsulosin only (n = 20), and the combination of both (n = 20) for 8 weeks. Changes from baseline in International Prostate Symptom Score (IPSS), maximum urinary flow rate (Q (max)), post voiding residual urine volume (PRV), Sexual Health Inventory for Male (SHIM) score, 3rd and 4th questions of International Index of Erectile Function (IIEF) were assessed at the end of the treatment. RESULTS The mean age was 58 years. IPSS, Q (max), PRV, SHIM scores, and 3rd and 4th questions in IIEF significantly improved in each group. Improvement of IPSS was more remarkable in combination (40.1%) and tamsulosin only (36.2%) groups in comparison with sildenafil citrate only group (28.2%; p < 0.001). Improvement of Q (max) and PRV were greater in tamsulosin only and combination than sildenafil citrate only group. SHIM scores significantly improved in sildenafil citrate only (65%) and combination (67.4%) than tamsulosin only (12.4%; p < 0.001). Increases in the 3rd and 4th questions of IIEF were greater in sildenafil only and combination than tamsulosin only (p < 0.001). CONCLUSIONS Treatment with the combination of tamsulosin only and sildenafil citrate only was not superior to tamsulosin only to enhance voiding symptoms. Also, sexual function improvement was similar for both the combination and sildenafil citrate only treatments.

Abstract
PURPOSE Endoscopic treatment of large bladder stones via cystoscope is still bothersome, and open cystolithotomy is the preferred method in many centers. To gain more insight into the endoscopic bladder stone management, we aimed to compare the transurethral use of nephroscope and cystoscope randomly. PATIENTS AND METHODS Forty-three male patients with bladder stones were randomized into two groups, to perform nephroscopic (group 1, n = 22) and cystoscopic (group 2, n = 21) stone fragmentation procedures transurethrally. Combined pneumatic/ultrasonic lithotripsy device was used in both groups to fragment the bladder stones. RESULTS The mean stone size in group 1 and group 2 was 3.6 +/- 1.3 cm and 3.5 +/- 1.6 cm, respectively (p > 0.05). Stone fragments were removed completely in all of the patients, and the mean operation time was calculated as 48.2 +/- 13.2 minutes in group 1 and 68.1 +/- 22.7 minutes in group 2, with no intraoperative complications (p < 0.01). None of the patients developed urethral stricture disease in the early (postoperative third month) follow-up. Three patients with previously known urethral stricture disease have shown to have the same disease in the late (postoperative 14.4 +/- 5.1 months) follow-up. CONCLUSION Treatment of large bladder stones by transurethrally placed nephroscope is a fast and effective treatment modality compared to endoscopic treatment via cystoscope. Nephroscope allows for use of larger forceps and facilitates collection of large stone fragments through its 24F sheath. It also prevents multiple entries to the urethra and hence avoids possible urethral injury. Combined pneumatic/ultrasonic lithotripsy device, with its aspiration quality, enables the surgeon to gain a better endoscopic view during both procedures.

Abstract
OBJECTIVES To determine whether the level of serum prostate-specific antigen (PSA) varies with fasting and nonfasting. METHODS The study involved 80 male patients with normal digital rectal examination who were hospitalized for benign urologic problems. The patients with active urinary tract infection, urologic cancer, urethral catheterization, diabetes mellitus, or acute or chronic renal failure and those who had undergone urologic manipulations within the past 45 days were excluded from the study. All the patients were asked to fast between 12:00 am and 8:00 am. The next morning, 10-mL venous blood samples were obtained at 8:00 am. Then each patient was provided with breakfast, which was followed by additional serial venous serum sampling during the first and second hour. The patients ate lunch at 12:00 pm. The final venous serum sampling was conducted at 2:00 pm. The serum PSA levels were determined for all the serum samples. RESULTS The mean patient age was 62.42 +/- 8.75 years (range 46 to 82). The mean serum total PSA value at fasting and the first, second, and sixth hour was 2.78 +/- 2.19, 2.7 +/- 2.0, 2.7 +/- 2.1, and 2.78 +/- 2.10 ng/mL, respectively. In the comparisons of the fasting values and first, second, and sixth hour values and the values at each hour with those at the other hours, no significant differences were observed (P > 0.05). CONCLUSIONS According to our results, blood samples can be obtained for serum PSA measurement at any time of the day, regardless of whether the patient has fasted or not.
