INTRODUCTION Lumbar discectomy constitutes the most common and probably easiest spine surgery but it is not without complications. The aim of this work is to report a case with total ureteral avulsion during lumbar discectomy due to careless advancement of the pituitary rongeur. METHODS A 59-year-old male presented with refractory left L5-S1 lumbar disc herniation. During the surgery, left si...

Ureteral disease can create a significant dilemma in our feline patients. The relatively common incidence of ureteral disease, combined with the invasiveness and morbidity associated with traditional surgical techniques, makes the investigation of minimally invasive alternatives appealing. Interventional radiologic (IR) and interventional endoscopic (IE) techniques, like ureteropyelography, per...

PURPOSE We report the clinical characteristics and the principles of laparoscopic management of ureteral endometriosis at our institution. MATERIALS AND METHODS We retrospectively reviewed the charts of patients with ureteral endometriosis. RESULTS Preoperatively 97% of patients complained of pain but only a third had urinary symptoms. The left ureter was affected in 64% of cases and diseas...

PURPOSE To review the feasibility of laparoscopic ureteroneocystostomy with extracorporeal eversion of the ureteral end in various distal ureteral lesions. MATERIALS AND METHODS We conducted a retrospective review of 5 laparoscopic procedures of ureteroneocystostomy with extracorporeal eversion of the ureteral end. Of these, 4 patients (range, 45 to 54 years) had distal ureter stricture or ob...

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...
