BACKGROUND AND OBJECTIVES The incidence of ureteral injuries is on the rise. Endoscopic treatment of long distal ureteral strictures is associated with poor success rates, and open ureteral reimplantation is a potentially morbid surgical procedure. The objective of this study was to review our early results with laparoscopic ureteral reimplantation. METHODS Between May 2004 and February 2007,...

PURPOSE OF REVIEW To review laparoscopic surgery in the treatment options for ureteral lesions in gynaecological surgery. RECENT FINDINGS Laparoscopic treatment of ureteral injuries has been increasingly reported over the past years. Treatment has progressively shifted from ureteroneocystostomy performed by laparotomy to less invasive treatment options such as ureteral stenting or dilatation ...

Moderate increases of ureteral back pressure usually cause decreases of glomerular filtration rate and even greater decreases of sodium excretion. It has been assumed previously that increased ureteral back pressure does not enhance renal tubular sodium reabsorption directly and that the decreases of sodium excretion are caused by the decreases of glomerular filtration rate. In the experiments ...

The α8 integrin (Itga8) chain contributes to the regulation of cell proliferation and apoptosis in renal glomerular cells. In unilateral ureteral obstruction Itga8 is de novo expressed in the tubulointerstitium and a deficiency of Itga8 results in more severe renal fibrosis after unilateral ureteral obstruction. We hypothesized that the increased tubulointerstitial damage after unilateral urete...

PURPOSE Previous reports suggest a high success rate for retrograde ureteral stenting for intrinsic ureteral obstruction, but few preoperative predictors of success have been offered. We reviewed our experience to look for factors that suggest failure of stents for intrinsic ureteral obstruction. MATERIALS AND METHODS We retrospectively reviewed the outcome of retrograde ureteral stent placem...

primary ureteral neoplasms are very rare and its prevalence is less than 1% of all genitourinary neoplasms. we report a symptomatic giant ureteral fibro epithelial polyp in adult women presenting as a bladder mass which was resected ureteroscopically and reported at the first time from iran. cystoscopy is growing use in the treatment of urinary tract lesions cystoscopy can be used in large lesi...

*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: To present our experience of laparoscopic ureteral reimplantation using intracorporeal ureteral tapering for management of distal ureteral stricture. Materials and Methods: Between April 2005 and October 2008, six patients, including 3 children and 3 adults, underwent laparoscopic modified Lich-Gregoir type extravesical ureteral reimplantation for distal ureteral stricture. Significant...

BACKGROUND Ureteral obstruction caused by extrinsic compression is often associated with intra-abdominal cancers. Internal drainage with ureteral stents is typically the first-line therapy to relieve such obstructions. Novel designs of ureteral stents made of different materials have been invented to achieve better drainage. In this study, we described the functional outcomes of a Resonance met...

PURPOSE A ureter obstruction caused by a ureteral stone results in inflammatory changes in the proximal submucosal layer and prevents the spontaneous passage of the ureteral stone. Accordingly, we analyzed the relationship between the spontaneous passage rates of ureteral stones less than 8 mm in size and serum C-reactive protein (CRP) levels and neutrophil percentages. MATERIALS AND METHODS ...
