OBJECTIVE To compare the clinical effects of three minimally invasive surgeries on the treatment of impacted upper ureteral calculi. METHODS 135 patients with impacted upper ureteral calculi were selected and randomly divided into three groups (Group A-C) (n=45), which were treated with transurethral ureteroscopic lithotripsy, minimally invasive percutaneous nephrolithotomy, and retroperitone...

This case report describes a distal ureteral atresia along with ureteropelvic junction obstruction which occurred in a 19-month-old female child. It is easily to be misdiagnosed as mere ureteropelvic junction obstruction and omitted the combined diagnosis of distal ureteral atresia. Dismembered pyeloplasty was done in local hospital after admission, however with the result of recurrent fever wh...

Double-j (DJ) ureteral stenting is a very common procedure performed after various endourological procedures. Although several complications due to DJ stent insertion were revealed, only three cases of renal parenchymal perforation have been reported to date. We present a case of a 35-year-old woman who had perforation of renal parenchyma without perirenal hematoma following insertion of DJ ure...

Uretero-retropentoneal fistulas (urinomas) occur most commonly following penetrating trauma or calculi. Despite the large variety of surgical procedures advocated for the management of ureteral fistulas or urinornas, the results are suboptimal. Conservative treatment by endoscopic placement of indwelling ureteral stents is often preferred. Adaptation of antegrade percutaneous stents offers an e...

We report a case of a benign fibroepithelial polyp of the lowermost ureter, which prolapsed into the bladder and was associated with a huge, impacted ureteral stone. The polyp was considered to have resulted from chronic irritation of the ureteral mucosa caused by the stone. Review of the literature showed that six out of 74 reported cases had concomitant stones but the polyp was apparently cau...

Spontaneous rupture of the ureter is an uncommon condition defined by non-traumatic extravasation of urine. Causative factors leading to rupture include urinary calculi, malignancies, instrumentation or trauma. Ureteral rupture can lead to numerous complications, including abscess formation, urinomas, and urosepsis. Minimal literature is available regarding spontaneous ureteral perforation, esp...

BACKGROUND The use of robotic assistance in adult genitourinary surgery has been successful in many operations, leading surgeons to test its use in other applications as well. METHODS Based on our use during prostatectomy, we have applied robotic surgery to complex distal ureteral surgeries since 2004 with successful outcomes. RESULTS A series of 11 patients who underwent robot-assisted lap...
