OBJECTIVE To investigate the outcome of laparoscopic repair of ureteral injury in laparoscopic gynecologic surgery. DESIGN Prospective trial. SETTING University hospital. PATIENT(S) Forty patients with a ureteral lesion in laparoscopic surgery between 1991 and 2007. INTERVENTION(S) Laparoscopic ureteral repair, laparoscopic-assisted or blind stent insertion. MAIN OUTCOME MEASURE(S) Tr...

PURPOSE We assess the safety, efficacy, and cost of the novel long-term indwelling thermo-expandable Memokath ureteral stent for the management of malignant and benign ureteral strictures. MATERIALS AND METHODS Since October 2004, we treated 73 patients (34 men), ages 23 to 84 years (mean 57.7) with 86 ureteral strictures (13 bilateral) with the Memokath 051 stent. The causes of the stricture...

BACKGROUND AND OBJECTIVES The success of laser tissue welding or soldering depends on optimal laser settings, solder material, and tissue type and geometry. To develop a practical laser welding technique for ureteral repair, an intraluminal albumin stent was designed to enhance the welding effects on ureteral end to end anastomosis. STUDY DESIGN/MATERIALS AND METHODS In vitro porcine ureters ...

PURPOSE We assessed the efficacy and safety of insertion of a polytetrafluoroethylene membrane-covered self-expandable metallic stent (UVENTA stent) for palliation of malignant ureteral obstruction on the basis of our early results. MATERIALS AND METHODS Eighteen patients underwent UVENTA stent insertion for extrinsic malignant ureteral obstructions of 20 ureters. The UVENTA stents were deplo...

PURPOSE We performed a prospective, randomized clinical trial to evaluate the outcome of ureteral stents for solitary ureteral stones 2 cm or less in moderately or severely obstructed systems using shock wave lithotripsy. MATERIALS AND METHODS Between 2001 and 2004, 186 patients who met study criteria were randomized into 2 groups. Group 1 received a pre-shock wave lithotripsy 6Fr Double-J st...

BACKGROUND The most important surgical complications of renal transplantation are stenosis and obstruction of anastomosis of the ureter to the bladder. Although the routine use of the ureteral stents to prevent such complications seems rational, the optimal time to keep the ureteral stent is still controversial. OBJECTIVES This study presents the benefits and complications of removing the ure...

Background and Objectives: We compared ureteral anastomosis using a laser and intraluminal albumin stent with both conventional suturing and laser soldering techniques. Study Design/Materials and Methods: Twelve pigs underwent bilateral ureteral anastomoses (N1⁄4 24) using one of the three anastomotic methods: (1) laser welding with intraluminal albumin stent (N1⁄4 11); (2) with albumin solder ...

OBJECTIVE To determine the incidence of urinary tract infection in those patients that we have used an ureteral double-J stent as internal diversion after urological procedures. MATERIAL AND METHODS We reviewed all the medical records of patients who had a ureteral double-J stent after a urological procedure from August 2007 to May 2013. We have analyzed the following data: age, gender, type ...

PURPOSE We evaluated the use of tamsulosine versus placebo for management of ureteral stent discomfort. PATIENTS AND METHODS This prospective and randomized study was realized in the Department of Urology of three university hospital. The participation was proposed at all patient having indication to receive an ureteral stent except for cancer. The evaluation of the tolerance used two validat...

Background: Ureteral stenosis is part of the common complications of renal graft reported in 3% to 7% of cases. Multiple treatments have been introduced regarding length and position of the stenosis. Metal stents for urologic purpose were created in 1998. Double percutaneous antegrade and transurethral retrograde access to a ureteral stenosis to a long-term metal stent procedure has been rarely...
