OBJECTIVES To assess the clinical role of corticosteroids in the medical expulsive therapy of symptomatic distal ureteral stones. METHODS Between January 2004 and September 2005, 114 patients with symptomatic distal ureteral stones with a >/=5mm diameter were enrolled in this prospective study and divided into four groups based on the urologist (of four)(More)
OBJECTIVE To demonstrate the safety of the Millin extraperitoneal laparoscopic adenomectomy by comparing the laparoscopic and open approaches. METHODS From January 2003 to April 2005, patients, with indication of prostatic adenomectomy, were offered the chance to choose between 2 types of procedure: Millin adenomectomy with open or extraperitoneal(More)
BACKGROUND AND PURPOSE Laparoscopic radical cystectomy is confined to centers where advanced laparoscopy is performed, and its role is not yet well clear. Our aim was to evaluate, through a prospective comparative study, the advantages of the laparoscopic compared with an open approach. PATIENTS AND METHODS From November 2002 to December 2005, all the(More)
Can vitrectomy help to understand the vitreous role in intermediate uveitis and Behçet's disease with vitritis without retinal detachment? 400 vitrectomies were decided because of vitreous changes but, over all, if macular changes were seen clinically or on the angiogram in 58 Behçet's disease and 342 intermediate uveitis including 59 children cases. Visual(More)
Scanning tunneling microscopy (STM) at liquid helium temperature is used to image potassium adsorbed on graphite at low coverage (≈0.02 monolayer). Single atoms appear as protrusions on STM topographs. A statistical analysis of the position of the atoms demonstrates repulsion between adsorbates, which is quantified by comparison with molecular dynamics(More)
PURPOSE To describe and demonstrate the feasibility of early ligature of the renal artery using a direct access to the renal pedicle at the level of the Treitz ligament during left transperitoneal radical laparoscopic nephrectomy. MATERIALS AND METHODS A total of 42 patient underwent left transperitoneal radical laparoscopic nephrectomies from February(More)
OBJECTIVE Laparoscopic partial nephrectomy (LPN) is a technique that is emerging as an attractive option for the treatment of renal tumors <or=4 cm. We retrospectively analyzed our experience with LPN to identify patient and tumor features that correlate with a higher risk of complications. MATERIAL AND METHODS From January 2001 to May 2007, 90 patients(More)
OBJECTIVE To evaluate renal damage and impairment of renal function 1 yr after laparoscopic partial nephrectomy (LPN) with warm ischemia >30 min. METHODS From July 2004 to June 2005, 18 patients underwent LPN with warm ischemia time >30 min. Kidney damage markers (daily proteinuria and tubular enzymes) and renal function (serum creatinine, cystatin C, and(More)
OBJECTIVES To evaluate, in a pilot prospective randomized trial, the safety, effectiveness and radiological recurrence of retroperitoneal renal cyst decortication compared with retroperitoneal decortication with wadding using perirenal pedicled fat tissue. PATIENTS AND METHODS From March 2004 to December 2007, 40 patients with simple renal cysts were(More)
OBJECTIVES To analyze, in a consecutive study, the perioperative, postoperative, and functional results of the transperitoneal and extraperitoneal approaches for laparoscopic radical prostatectomy. METHODS A total of 160 patients underwent radical prostatectomy and were subdivided into two groups. Group 1 underwent the transperitoneal approach and group(More)
