Purpose: We investigated role of neutrophil-to-lymphocyte ratio (NLR) in the diagnosis and prediction of extracapsular extension (ECE) in clinically localized prostate cancer (PCa). Materials and methods: A total of 396 patients with clinically localized PCa who underwent open radical retropubic prostatectomy (RRP), and 260 patients with benign prostatic hyperplasia (BPH) who underwent suprapubic prostatectomy were included in the study. Preoperative NLR, prostate specific antigen (PSA), prostate specific antigen density (PSAD), free PSA, prostate volume (PV), free/total PSA (f/t PSA) in both groups, and relation of NLR with PSA, Gleason Score (GS), and pathologic stage in PCa group were investigated. Records of patients were analyzed retrospectively. Results: NLR, free PSA, f/t PSA, and PV were statistically higher in BHP, and PSAD was higher in PCa group. In PCa group, NLR was found to be higher in patients with PSA >10 ng/ml compared to those with less than ⩽10 ng/ml. NLR increases as the preoperative GS increases, and it was higher in pT3 patients than pT2 patients. NLR was statistically higher in those patients with positive lymph nodes than those without after RRP (p = 0.029). Conclusion: NLR is not a sufficient biomarker in differentiating clinically localized PCa from BPH. NLR increases as preoperative GS and pathologic stage increases. Lymph node involved patients after RRP have statistically higher NLR. NLR can be an indicator of ECE and lymph-node involvement in clinically localized PCa. [ABSTRACT FROM AUTHOR]

Objective: In our study, we aimed to evaluate the parameters that are effective in predicting the possibility of stone migration during ureteroscopic lithotripsy. Patients and method: We divided our patients two group whom we applied ureteroscopic lithotripsy. Patients who migrated stones during ureteroscopic manipulation to the 1st group, and the patients who did not migrate stones to the second group were included. We measured the proximal ureter diameters of the patients in both groups on their computed tomography. We compared these values statistically. In addition, we determined a cut-off value for the ureter diameter to predict the possibility of stone migration. Result: Especially, ureter diameters of patients with middle and lower ureter stones showed significant differences between groups. Also, stone sizes differed significantly between groups. Conclusion: We concluded that the possibility of stone migration is high in patients with a ureter diameter higher than 7.45 mm in the middle and lower ureteric stones. Also, we believe that stone diameter and the surgeon's experience are effective factors in stone migration. [ABSTRACT FROM AUTHOR]

Purpose: We aimed to present our laparoscopic cystectomy experience and demonstrate that it is a feasible technique with safe oncologic principles. Methods: Total 19 patients who underwent laparoscopic radical cystectomy and pelvic lymph node dissection (PLND) in our urology clinic (Okmeydani Training and Research Hospital) were retrospectively evaluated. Demographic data, operation technique and complications, tumour pathology and follow-up details of patients were recorded. Results: Patients ranged from 40 to 73 years, with the average age of 60.8 and female/male rate was 2/17. The mean total operation time was 375 min (range 260–500). Mean hospitalisation time of patients was 10.3 days. The mean follow-up time was 11.2 months. Conclusion: Minimally invasive approaches in urology are becoming the first line treatment by the time. Due to the high costs and limited availability, robotic surgery is still not exactly widespread in the world. Our series showed that conventional laparoscopic cystectomy is an appropriate approach until robotic surgery becomes widespread. [ABSTRACT FROM AUTHOR]

Purpose: Prediction of extracapsular extension (ECE) before radical prostatectomy in clinically localized prostate cancer (PCa) is very important for clinical practice. ECE affects our decision on treatment strategy. The aim of this study is to identify the predictors of ECE, determine cut-off values, and compare them with the accuracy of Partin Table parameters to improve tumor staging in clinical practice.Materials and Methods: 374 patients with clinically localized PCa who underwent open radical retropubic prostatectomy (RRP) were included in this study. Gleason Score (GS), age, digital rectal examination (DRE), prostate specific antigen (PSA), prostate specific antigen density (PSAD), free PSA, Free/Total PSA, prostate volume (PV), number of cores involved, tumor length, and tumor percentage in maximum involved core in biopsy were investigated.Results: PSAD, tumor percentage, and tumor length are predictive factors of ECE. The cut-off values of PSA, PSAD, maximum tumor length, and maximum tumor percentages in predicting ECE are: > 8.90 ng/mL, > 0.26 ng/mL2, >5mm, and >50%, respectively. The cut-off values for Partin extraprostatic extension (EPE) and organ confined (OC) disease are >29% and ≤ 64%, respectively.Conclusion: Partin tables could better predict extracapsular extension in clinically localized PCa if they include PSAD, tumor percentage, and tumor length. The cut-off values of these predictive factors can be beneficial in treatment strategies and in the decisions of lymphadenectomy and nerve-sparing surgery at radical prostatectomy.

Objective: To assess the safety and effectiveness of percutaneous nephrolithotomy in aging male patients.Methods: Two hundred eighty-three male patients over the years of forty undergoing percutaneous nephrolithotomy between December 2009 and September 2014 were evaluated, retrospectively. The patients were stratified by four age groups [40-49 (group-1), 50-59 (group-2), 60-69 (group-3), ≥70 years (group-4)]. The groups were compared regarding stone size, mean operation time, mean access number, mean nephrostomy removal time, hospitalization duration, stone-free rate, and complications rate. The patients were also evaluated with regard to glomerular filtration rate levels preoperatively and in the sixth month after surgery.Results: Mean stone size was 810 ± 490 mm2 in group-1, 840 ± 500 mm2 in group-2, 845 ± 480 mm2 in group-3, and 800 ± 460 mm2 in group-4 (p = .02). There was no statistical difference between the four groups in terms of mean operation time, access number, hemorrhage, nephrostomy removal time, and hospital stay duration (p > .05). After additional interventions; no significant difference was detected for final stone-free rates among the groups (p = .12). A significant improvement was detected in glomerular filtration rate levels in the sixth month after surgery in all groups (p < .05).Conclusion: These results indicate that percutaneous nephrolithotomy is a safe and effective method in aging male patients.
