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...

There are four types of ureteral metal stents: self expandable, balloon expandable, covered, and thermoexpandable shape-memory. Insertion of metal stents requires expertise with transurethral and percutaneous techniques. The stricture is traversed with the aid of a guidewire via a percutaneous nephrostomy, and the stenotic segment is dilated using a high-pressure balloon catheter. The stent is ...

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...

More than 90% of renal injuries in children result from blunt abdominal trauma. A 10-year-old female had a blunt abdominal trauma with macro-hematuria. The computed tomography scan revealed the presence of a horseshoe kidney and a 3rd grade renal lesion and contrast leakage from the right ureter. The ureteral rupture was confirmed by cystoscopy and ascendant pyelography and than a double J-sten...

BACKGROUND The 2008 American Urological Association (AUA) Best Practice Statement on antimicrobial prophylaxis states that prophylaxis is not warranted for subjects with normal risk profile undergoing cystourethroscopy unless manipulation such as ureteral stent removal is performed. To date no studies have specifically assessed the need for antimicrobial prophylaxis during cystoscopic ureteral ...
