A 23-year-old female had bilateral ureteral stents placed due to bilateral renal stones and hydronephrosis. The bilateral ureteral stents were changed every 3 months. A kidney ureter bladder (KUB) film showed left encrustation along the ureteral stent thus necessitating removal; however, the ureteral stent could not be removed cystoscopically. The ureteral stent was, therefore, extracted using ...

PURPOSE To determine predictive factors for stent failure-free survival in patients treated with a retrograde ureteral stent for a malignant ureteral obstruction. MATERIALS AND METHODS We retrospectively reviewed 71 patients who underwent insertion of a cystoscopic ureteral stent due to a malignant ureteral obstruction between May 2004 and June 2011. Performance status, type of cancer, hydron...

Ureteral fistula is a serious complication of abdomino-pelvic surgeries, often resulting in poor outcomes owing to lack of proper treatment. We report the case of a 49-year-old woman who underwent placement of a silicone-covered ureteral occlusion stent in her right ureter for the management of ureteral leakage after pelvic surgery. A ureterogram obtained 18 months following the stent placement...

from july, 1987 to oct, 1989 , 104 patients underwent 111 transurethral ureteroscopy procedures at the air force medical center. all intramural ureters were dilated by flexible metal dilators. the overall success rate for ureteral stone removal was 95.8 per cent. ureteroscopy was done for evaluation of gross hematuria, strictures, ureteral stent, and ureteral and pyelocalyceal tumors. the overa...

OBJECTIVE Urinary tract obstruction is one of the most prevalent diseases in urology. The handling of it includes conservative (analgesia and fluid therapy) and invasive (urinary diversion) measures. Ureteral stent is the method currently employed for urinary tract diversion. Complications of urinary tract stents maintenance have already been studied and are well known. We report a case of ur...

*E-mail: [email protected] We report a rare case of an ectopically placed ureteral stent, which was acceptable and functional. obstructing 8 × 15-mm proximal right-sided ureteral calculus. There were also multiple nonobstructing renal calculi on the left side. An antegrade ureteral stent was placed to relieve his infected and obstructed right kidney. During stent placement, the interventional ra...

PURPOSE Malignant ureteral obstruction often necessitates chronic urinary diversion and is associated with high rates of failure with traditional ureteral stents. We evaluated the outcomes of a metallic stent placed for malignant ureteral obstruction and determined the impact of risk factors previously associated with increased failure rates of traditional stents. MATERIALS AND METHODS Patien...

Ureteral stents are widely used in urology clinics to protect urinary flow. The complications of ureteral stent implantation are observed more frequently with the increased use of these stents. Early complications of double-J (DJ) ureteral stents are stent discomfort, irritative bladder symptoms and hematuria.[1] In contrast, migration, encrustation, and fragmentation are the most frequent comp...

The Resonance(®) metallic ureteral stent is one of the latest additions to the urologist's armamentarium in managing ureteral obstruction. One advantage of this stent over traditional polymer-based stents is resistance to encrustation with stone material, which allows longer dwell times and less frequent exchange procedures. Although exchanging a metallic stent is slightly more complicated than...

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 ...
