INTRODUCTION This work evaluates the results of ureteroscopic treatment of impacted ureteral stones with a pneumatic lithotripter. MATERIALS AND METHODS From March 1997 to May 2002, 42 patients with impacted ureteral stones were treated by retrograde ureteroscopic pneumatic lithotripsy. Twenty-eight patients were female and 14 were male. The stone size ranged from 5 to 20 mm. The ureteral sit...

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...

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 We evaluated the effectiveness and safety of holmium: YAG laser lithotripsy with a semirigid ureteroscope for ureteral calculi in a prospective cohort of 697 patients. PATIENTS AND METHODS Holmium: YAG laser lithotripsy was performed with a semirigid ureteroscope in 697 inpatients between September 2002 and January 2006. Calculi were located in the distal ureter in 382 patients (54.8%...

*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...

Study population The study population comprised adult patients with a solitary, radiopaque distal ureteral calculus below the bony pelvis, 15mm or less in diameter. Exclusion criteria were multiple ureteral calculi, solitary kidney, renal insufficiency, ipsilateral ureteral stricture, plan for simultaneous treatment of ipsilateral renal or contra lateral renal or ureteral calculi, active urinar...

BACKGROUND Laser lithotripsy is an established endourological modality. Ho:YAG laser have broadened the indications for ureteroscopic stone managements to include larger stone sizes throughout the whole upper urinary tract. Aim of current work is to assess efficacy and safety of Ho:YAG laser lithotripsy during retrograde ureteroscopic management of ureteral calculi in different locations. MET...
