conclusions this case raises awareness on the lack of visualization of ureteral flux during conventional cystoscopic evaluation in patients with renal failure undergoing pelvic organ prolapse repair, while also emphasizing the importance of confirming ureteral patency via retrograde ureteral intubation when cystoscopy is non-diagnostic. background pelvic floor reconstruction can result in obstr...

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 to 80) with ureteral obstruction due t...

BACKGROUND The Resonance(®) metallic stent has been reported to be sufficient for the management of malignant extrinsic ureteral obstructions within a 12-month time period. To determine the effectiveness in each specific patient group, we report our experience using the Resonance(®) stent in the treatment of ureteral obstructions. METHODS We retrospectively reviewed 20 patients (23 stents) wh...

PURPOSE To report the long-term follow-up results of peripheral cutting balloon incision and dilatation (PCBID) after failed high-pressure balloon dilatation in patients with benign ureteral and biliary strictures. MATERIALS AND METHODS The study included 9 patients (5 males and 4 females) who underwent successful PCBID procedures. Of these, 4 patients had biliary strictures; 2 of them had ch...

PURPOSE To review the role of minimally invasive management in ureteral stricture disease. MATERIALS AND METHODS A literature search was performed on the MEDLINE database through 2002 concerning endoscopic treatment of patients with ureteral strictures. RESULTS Many endourologic methods are available for ureteral strictures. Ureteral dilation may be accomplished in most cases, with various ...

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...

There are occasional reports of using the appendix to replace sections of the ureters, and to our knowledge, only a couple of them were in the left side. We used the appendix as a ureteral substitute in two cases in technically difficult parts, the upper left ureter and the first part of the right ureter. Follow-ups of8 years and 6 months in right and left side cases, respectively, are imp...

Dear Editor: The ureteral stents are defined as devices that are inserted inside obstructive ureters to maintain patency. Ureteral obstruction caused by extrinsic compression is a challenge in the management of malignant diseases. First, adequate stent placement across an obstructed ureter does not necessarily guarantee urine patency. Moreover, the stent is poorly tolerated, severely impairing ...

Ureteral stents are one of the most commonly used urologic devices with the purpose of establishing and maintaining ureteral patency. They are also associated with a number of complications including infection, migration, stent-related symptoms, and encrustation, leading to lithiasis. Prolonged stent dwell time is associated with a greater degree of these complications. We present the case of a...
