PURPOSE We compared biochemical recurrence-free survival of patients who underwent radical retropubic prostatectomy vs robot assisted laparoscopic prostatectomy in concurrent series at a single institution. MATERIALS AND METHODS A total of 2,132 patients were treated between June 2003 and January 2008. We excluded from study patients with prior treatment(More)
OBJECTIVE To determine whether robotic-assisted laparoscopic radical prostatectomy (RALP) is associated with a lower transfusion rate than radical retropubic prostatectomy (RRP). PATIENTS AND METHODS In this cohort study, we evaluated 1244 consecutive patients who underwent RALP (830) or RRP (414) between June 2003 and July 2006. Demographics, clinical(More)
We investigated the risk factors for community acquired/onset urinary tract infections due to extended spectrum beta-lactamase (ESBL)-positive Escherichia coli or Klebsiella pneumoniae in 62 patients who were followed-up from August 1, 2003 to September 1, 2006. Sixty patients with community-acquired urinary tract infections caused by ESBL-negative E. coli(More)
OBJECTIVE Urolithiasis has a strong familial component. However, to date, no specific genetic abnormality has been identified. It has been reported that allelic variation in the vitamin D receptor (VDR) gene may affect calcium absorption and excretion. Urolithiasis is a multifactorial disease in which both genetic and environmental factors have an effect on(More)
The prognostic value of tumor volume in predicting biochemical recurrence after prostatectomy has been debated. Our aim in this study was to (a) evaluate tumor volume as an independent predictor of adverse pathologic outcomes and BCR and (b) determine the effect of two different methods of tumor volume estimation. We reviewed the charts of 3,087 patients(More)
PURPOSE We evaluated whether the 2002 TNM substages of pathological T2 prostate cancer predict intermediate term biochemical recurrence-free survival. MATERIALS AND METHODS The cohort consisted of men who underwent radical prostatectomy between January 2000 and June 2008, and had pT2 disease at final pathological evaluation. We excluded patients with(More)
PURPOSE To evaluate the efficacy of intraoperative local anesthetic infiltration in combination with intravenous paracetamol infusion on postoperative pain management in patients who underwent percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS Sixty adult patients were randomized into three groups with 20 cases in each: Group SP, 20 mL saline was(More)
PURPOSE To evaluate the feasibility of laparoscopic simple prostatectomy for large volume prostates. MATERIALS AND METHODS Between October 2007 and July 2009, laparoscopic simple prostatectomy was performed on 16 patients with the prostates over 80 mL. All the patients were operated with transvesical method. Peri-operative and 3rd postoperative month data(More)
OBJECTIVE To investigate the adequacy of the samples obtained by prostate biopsies and the factors those could affect this adequacy. MATERIALS AND METHODS Three hundred seventy-eight patients who underwent transrectal ultrasound guided biopsy have been included into the study. The biopsy samples have been retrospectively reviewed in terms of presence of(More)
OBJECTIVE To evaluate the correlation between cyclooxygenase-2 (Cox-2) expression and clinicopathologic findings with the effect of these variables on prognosis of bladder cancer. METHODS Cox-2 expression was examined immunohistochemically in paraffin blocks of 99 patients. Correlations between Cox-2 expression and variables like cancer stage and grade,(More)
