PURPOSE This retrospective study evaluated the unenhanced multi-detector computed tomography (MDCT) findings of urinary system calculi and the secondary signs associated with ureteral stones in children. MATERIALS AND METHODS The study included 87 children (54 boys, 32 girls) with a mean age of 89 months (range: 5 months to 16 years) who were referred to us from various departments and were e...

Objectives. We compared outcome and complications after uncomplicated ureteroscopic treatment of distal ureteral calculi with or without the use of ureteral stents. Materials and Methods. 117 patients, prospectively divided into three groups to receive a double j stent (group 1, 42 patients), ureteral stent (group 2, 37 patients), or no stent (group 3, 38 patients), underwent ureteroscopic trea...

PURPOSE To correlate the presence of secondary signs of non-enhanced computed tomography (NECT) in renal units harboring ureteral calculi with intraoperative findings and treatment outcome after holmium:yttrium-aluminum-garnet laser (Ho:YAG) ureterolithotripsy. SUBJECTS AND METHODS Two-hundred patients were prospectively included after ureteral calculi were detected on NECT. All patients unde...

INTRODUCTION Ureteral trauma is rare, accounting for less than 1% of all urologic traumas. However, a missed ureteral injury can result in significant morbidity and mortality. The purpose of this article is to review the literature since 1961 with the primary objective to present the largest medical literature review, to date, regarding ureteral trauma. Several anatomic and physiologic consider...

Ureteral stents coated with the quorum-sensing inhibitor RNAIII-inhibiting peptide (RIP) were implanted in rat bladders and shown to suppress Staphylococcus aureus formation on the stent and in urine and was especially effective when combined with teicoplanin. Coating ureteral stents with RIP thus increases the efficacy of teicoplanin in preventing ureteral stent-associated staphylococcal infec...

OBJECTIVE Ureteral stents are widely used in endo-urological procedures. However, ureteral stents can be forgotten and cause serious complications, including fragmentation, migration and urosepsis.There are few reports about forgotten and fragmented ureteral stents with stone formation. We aimed to present this rare case with successful combined endo-urological management.

PURPOSE Since the holmium:yttrium-aluminum-garnet (Ho:YAG) laser is the flexible lithotrite of choice for ureteral stones, its application to ureteral strictures associated with ureteral calculi is convenient. The results of Ho:YAG laser endoureterotomy in this specific setting have not been defined. We report our experience with Ho:YAG laser endoureterotomy of ureteral strictures associated wi...

INTRODUCTION We intended to evaluate the feasibility and effectiveness of the simultaneous rigid and flexible ureteroscopic treatment of symptomatic ureteral and ipsilateral small simultaneous calyceal stones. Outcomes of combined therapy were compared with monotherapy alone. MATERIAL AND METHODS In this retrospective study, group 1 consisted of 45 patients with middle or lower ureteral and i...

Purple urine bag syndrome is a rare phenomenon whose striking presentation can lead to earlier recognition and treatment of potentially serious medical condition. This unique condition long11 term indwelling catheter associated urinary tract infection with distinct, purple-colored caused by bacterial metabolites. infrequent occurrence was seen in patient stage IIIb squamous cervical cancer who ...

OBJECTIVE The incidence of ureteral stricture is showing a rising trend due to increased use of laparoscopic and upper urinary tract endoscopic procedures. Boari flap is the preferred method of repairing long- segment ureteral defects of 8-12 cm. The procedure has undergone change from classical open (transperitoneal and retroperitoneal) method to laparoscopic surgery and recently robotic surge...
