OBJECTIVE To investigate the efficacy of near infrared spectroscopy (NIRS) and an algorithm on the diagnosis of bladder outlet obstruction in men with lower urinary tract symptoms (LUTS). METHODS Male patients with LUTS were recruited and underwent uroflowmetry and urodynamic pressure flow study (PFS) with simultaneous transcutaneous NIRS monitoring. Next, the postvoid residual urine volume was measured using ultrasonography. Data analysis first classified each subject as obstructed or unobstructed using the standard pressure flow data and nomogram and compared these results with the NIRS algorithm, which analyzed the pattern of change of the NIRS data plus the measurements of the postvoid residual urine volume and peak flow rate on uroflowmetry. RESULTS A total of 65 patients were enrolled in the present study. Of these patients, 10 with equivocal PFS findings and 2 with concurrent urinary tract infection were excluded. Of the 53 patients, 29 and 24 were classified as obstructed and unobstructed according to the PFS outcomes, respectively. The International Prostate Symptom Score and uroflowmetry peak flow rate demonstrated significant differences between the obstructed and unobstructed patients. The NIRS algorithm correctly identified 25 patients diagnosed as obstructed (86.2%) and 21 diagnosed as unobstructed (87.5%) according to the PFS findings. CONCLUSION The NIRS algorithm could be a noninvasive option for the diagnosis of bladder outlet obstruction in men with LUTS, with 86.2% and 87.5% sensitivity and specificity, respectively.

INTRODUCTION The discrepancy between prostate biopsy and prostatectomy Gleason scores is common. We investigate the predictive value of prostate biopsy features for predicting Gleason score (GS) upgrading in patients with biopsy Gleason scores ≤6 who underwent radical retropubic prostatectomy (RRP). Our aim was to determine predictors of GS upgrading and to offer guidance to clinicians in determining the therapeutic option. METHODS We performed a retrospective study of patients who underwent RRP for clinically localized prostate cancer at 2 major centres between January 2007 and March 2013. All patients with either abnormal digital examination or elevated prostate-specific antigen at screening underwent transrectal ultrasound-guided prostate biopsy. Variables were evaluated among the patients with and without GS upgrading. Our study limitations include its retrospective design, the fact that all subjects were Turkish and the fact that we had a small sample size. RESULTS In total, 321 men had GS ≤6 on prostate biopsy. Of these, 190 (59.2%) had GS≤6 concordance and 131 (40.8%) had GS upgrading from ≤6 on biopsy to 7 or higher at the time of the prostatectomy. Independent predictors of pathological upgrading were prostate volume <40 cc (p < 0.001), maximum percent of cancer in any core (p = 0.011), and >1 core positive for cancer (p < 0.001). CONCLUSIONS When obtaining an extended-core biopsy scheme, patients with small prostates (≤40 cc), greater than 1 core positive for cancer, and an increased burden of cancer are associated with increased risk of GS upgrading. Patients with GS ≤6 on biopsy with these pathological parameters should be carefully counselled on treatment decisions.

A 48-year-old man was hospitalized with the chief complaints of lower abdominal pain, pain during micturation and pollakuria. Plain radiography showed 2 giant bladder stone shadows: one as 6.0 × 5.0 cm and the other one 5.0 × 5.0 cm in size. Cystolithotomy was performed. The first stone weighed 400 g and measured 6.0 × 5.0 × 6.0 cm in size, and the other stone was fragmented to smaller particles with pneumatic lithotriptor. Although a bladder stone is not rare, this case is interesting for 2 huge bladder calculi that were completely obstructing the bladder outlet and observed several years following pelvic trauma. To the best of our knowledge, our patient represents one of the largest bladder stone cases reported to date.

Objective: In this study we aimed to compare photoselective vaporization (PVP) with the GreenLight 120-W Laser and monopolar transurethral resection as surgical treatments of prostates less than 80 cc in men with obstructive benign prostatic hyperplasia. Methods: From February 2009 to March 2012 we allocated 101 patients with a prostate glands of less than 80 cc; patients were randomly assigned for surgical treatment with monopolar transurethral resection of the prostate (TURP) (n = 62) or PVP (n = 39). Serum prostate specific antigen (PSA), International Prostate Symptom Score (IPSS), Sexual Health Inventory for Men (SHIM), maximum flow rate (Qmax) postmicturition residual (PMR), transrectal ultrasound volumes (TRUS), postvoid urine residual (PVR), complications, re-operations and hospitalization time were collected. The patients were seen in the follow up at 6, 12 and 24 months. Results: Median age was 69 (56–87) years old in the TURP group and 67 (51–87) years old in the PVP group. Mean preoperative prostate volume was 55 cc (40–72) and 60 cc (41–75) cc in the TURP group versus the PVP group. There was no statistically difference in subjectively (IPSS, SHIM) and objectively (Qmax-PMR) parameters and postoperatively complication rates between the two groups (p > 0.05). A significant difference was observed in the PVP group with a 2 (1–4) days hospital stay compared with 5 (3–9) days for the TURP group (p < 0.001). Conclusion: Prostate PVP and TURP are effective surgical treatments for benign prostatic hyperplasia. Postoperative functional improvements were durable and equivalent in the two groups. The two techniques have a similar complication rate.

INTRODUCTION We evaluated the prognostic effects of hematologic parameters of preoperative leukocytosis and neutrophil-to-lymphocyte ratio (NLR) in patients who underwent radical cystectomy for bladder cancer. METHODS We retrospectively reviewed the medical records of 363 patients who underwent radical cystectomy for bladder cancer between January 1990 and June 2013. In total, 286 patients were included in the study. Age, gender, pathologic stage, lymph node involvement, preoperative hydronephrosis, histologic sub-type, surgical margin status, and lymphovascular invasion were recorded for each patient. Univariate and multivariate analysis were performed to determine the prognostic value of the preoperative clinical and laboratory parameters on disease-specific survival (DSS). Additionally, the correlation between leukocytosis and other factors were evaluated. RESULTS According to the univariate analysis preoperative leukocytosis and NLR were detected as negative prognostic factors on DSS. Preoperative leukocytosis, NLR, stage, lymph node involvement, histologic subtype, grade and age were independent prognostic factors for DSS, on multivariate analysis. Patients with leukocytosis had higher stage, grade and lymphovascular invasion. CONCLUSIONS Inexpensive, reproducible, and readily available peripheral blood count components of white blood cell count and NLR were independent prognostic factors, which can stratify DSS risks in bladder cancer patients who underwent radical cystectomy.

Aims To investigate the prevalence and risk factors of overactive bladder syndrome and urinary incontinence in Turkish women; furthermore, to assess the impact on the quality of life. Materials and Methods A cross-sectional, epidemiological study was carried out in women of reproductive age to define overactive bladder syndrome, urinary incontinence, ICIQ-SF score and medical care seeking. Results The womens average age was 34.4 ± 5.26 years. The prevalence of UI was 26.9%. Stress UI was the predominant form. The prevalence of UI increased with age, BMI, number of pregnancies and children delivered. The prevalence of OAB was 20.7%. Women with OAB were older and had greater number of pregnancies than women without OAB. History of nocturnal enuresis was a significant risk factor for OAB and UUI. Women with MUI had more frequent and more abundant leakage of urine. 10.7% of women sought medical care for their condition. Conclusions Although prevalence estimates differ across studies, the available evidence indicates that UI and OAB are highly prevalent conditions among women. UI had negative effect on QoL, but only severely-affected women sought medical care. Public health and clinical management programs are needed to determine diagnosis and management of these social problems.

Bladder urothelial carcinoma is rare in young adults and occurs more commonly in older individuals. The aim of this study was to compare the clinical behavior, pathologic characteristics, and prognosis of urothelial carcinoma of urinary bladder in young versus older adults. A retrospective review of our records between 2007 and 2013 identified 56 patients (42 males and 14 females) with transitional cell carcinoma of the bladder who were less than 40 years old. Clinical and pathological parameters of patients who were less than 40 years of age were compared with those of a series of patients older than 40 years of age (the control group) during the same period. A survival analysis was performed using the Kaplan–Meier method and log‐rank test, and Cox regression was performed to identify clinical parameters that affected the clinical outcomes. The mean age was 29.21 years (range, 5–40 years) for patients less than 40 years old and 61.66 years (range, 41–75) for those older than 40 years. The mean follow‐up was 40.26 months (range, 12–65 months) for young patients and 42.57 months (range, 12–72 months) for the older patients. Young bladder cancer patients had smaller‐sized tumors (less than 3 cm), less high‐grade cancers, higher papillary urothelial neoplasms of low malignant potential, and low‐grade tumors than patients older than 40 years. Multivariate logistic regression analysis predicted tumor recurrence in young patients with high‐grade tumors [odds ratio (OR), 1.959; 95% confidence interval (CI), 1.235–2.965; p = 0.046] and tumors larger than 3 cm (OR, 1.772; 95% CI, 1.416–1.942; p = 0.032). The 5‐year overall survival rate was 100% for young patients and 88.1% for older patients. No difference was observed in the recurrence‐free (p = 0.321) and progression‐free (p = 0.422) survival rates between the two groups. We concluded that although the clinical stage distribution, natural history, and outcomes of bladder urothelial cancer in young adults are similar to those in their older counterparts, clinicians must be aware that patients under 40 years of age presented with higher‐grade and larger (>3 cm) tumors and are more likely to experience tumor recurrence.

Introduction: The aims of this study were to investigate the effect of varicocelectomy on DNA fragmentation index and semen parameters in infertile patients before and after surgical repair of varicocele. Materials and Methods: In this prospective study, 72 men with at least 1-year history of infertility, varicocele and oligospermia were examined. Varicocele sperm samples were classified as normal or pathological according to the 2010 World Health Organization guidelines. The acridine orange test was used to assess the DNA fragmentation index (DFI) preoperatively and postoperatively. Results: DFI decreased significantly after varicocelectomy from 34.5% to 28.2% (P = 0.024). In addition all sperm parameters such as mean sperm count, sperm concentration, progressive motility and sperm morphology significantly increased from 19.5 × 10 6 to 30.7 × 10 6 , 5.4 × 10 6 /ml to 14.3 × 10 6 /ml, and 19.9% to 31.2% (P < 0.001) and 2.6% to 3.1% (P = 0.017). The study was limited by the loss to follow-up of some patients and unrecorded pregnancy outcome due to short follow-up. Conclusion: Varicocele causes DNA-damage in spermatozoa. We suggest that varicocelectomy improves sperm parameters and decreases DFI.

Background: To determine association between urine pH and OAB symptoms and to determine if urinary alkalization improves overactive bladder (OAB) symptoms. Methods: 659 patients with OAB were enrolled in this study between June 2012 and May 2014. 329 patients (group 1) were included in the final analysis. 201 adults were used as a control group (group 2). 24-hour urinary pH and the validated Turkish version of the OAB-V8 questionnaire were performed in patients. A 24-hour urine pH <6.2 was considered acidic urine. In the second part, a diet program was performed for 4 weeks in 30 participants. Urine pH values and OAB-V8 scoring results were recorded before the diet program and 2 and 4 weeks after the diet program. Results: Acidic urinary pH was determined in 61.4% of patients with OAB. There was a significant association between the presence of acidic urine and OAB. Also, the OAB-V8 scores of patients were significantly higher in patients with acidic urine than nonacidic urine. OAB-V8 scores of patients showed statistically significant improvement after diet therapy (17.87 ± 6.52 vs. 10.43 ± 7.17; p < 0.001). Conclusions: We found that acidic urinary pH was closely associated with OAB, and alkalization of urine improved lower urinary tract symptoms. We suggest that urinary pH should be considered as a parameter in treatment planning of patients with OAB.
