OBJECTIVE The current study investigates the effect of bladder neck (BN) preservation on postoperative continence and positive surgical margins (+SMs). PATIENTS AND METHODS 150 patients (group 1) who underwent BN-sparing endoscopic extraperitoneal radical prostatectomy (EERPE) and 90 patients treated with EERPE and BN resection (group 2) were(More)
PURPOSE To evaluate the effect of vardenafil on renal function after renal ischemia-reperfusion (IR) injury (IRI) in a rat model. MATERIALS AND METHODS Seventy-one Wistar rats were divided into 7 groups including (1) a vehicle-treated group, (2) a vehicle pretreated-IR group, (3-6) vardenafil pretreated-IR groups in doses of 0.02, 0.2, 2 and 20 μg/kg,(More)
PURPOSE Ureteral patency in malignant ureteral obstruction cases is a therapeutic challenge. We report our long-term experience with palliative treatment for extrinsic malignant ureteral obstruction with percutaneous placement of metal mesh stents. MATERIALS AND METHODS From January 1996 to December 2005, 90 patients with a mean age of 59 years (range 35(More)
Drugeluting metal stents (DESs) have been extensively used in coronary and vascular disease. This type of stents has been proven to provide significantly lower restenosis rates due to the reduction of neo-intimal hyperplasia in comparison to the traditionally used bare metal stents (BMSs). The latter stents have been evaluated for more than a decade in(More)
This study aimed at comparing the success rates of silodosin to the most commonly used for medical expulsive therapy (MET) tamsulosin for the management of ureteral stones. A systematic review using the search string: "silodosin AND (ston* OR calcu* OR expul*)" was conducted on Pubmed, SCOPUS, Web of Science, Cochrane Central Register. The Primary endpoint(More)
OBJECTIVES To perform a survey of the current state of laparoendoscopic single-site surgery (LESS) and its implementation in the treatment of malignant disease of the urinary tract. Although it is a recent development in the field of laparoscopic surgery with still unproven long-term results, LESS may prove to be more commonly performed in the coming years(More)
UNLABELLED Objectives should be describe a modular training scheme (MTS) which aims to provide training in percutaneous nephrolithotripsy (PCNL) and ensure the safety of the patients. SUBJECTS AND METHODS Two trainees with no experience in PCNL attended the MTS under the supervision of an experienced mentor. The MTS included five modules, comprising an(More)
The laparoscopic approach has been established as the surgical procedure of choice for radical nephrectomy during the recent years. The advantages of the laparoscopic radical nephrectomy in comparison to the open approach are well-documented. The oncological results of the laparoscopic approach are similar to the open procedure while the post-operative(More)
The full metallic double-J ureteral stent (MS) was introduced as a method for providing long-term drainage in malignant ureteral obstruction. Experimental evaluation of the MS revealed that its mechanical features allow efficient drainage in difficult cases, which could not be managed by the insertion of a standard polymeric double-J stent. Clinical(More)
INTRODUCTION Evaluation of ketamine and propofol combination for the performance of photoselective vaporization of prostate (PVP). PATIENTS AND METHODS Twenty-six patients undergoing PVP for benign prostatic hyperplasia were included in the study. Co-morbidities were present in 24 patients. Midazolam 2 mg intravenous was administered for the induction to(More)
