Endoscopic management of obstructive complications in ureterosigmoidostomy. Urology Eisenberg, M. L., Lee, K. L., Stoller, M. L. 2007; 70 (6): 1048-1052


Although rarely used today for supravesical urinary diversion, ureterosigmoidostomy remains useful in patients with bladder exstrophy. However, management of ureteral stricture and ureteral urolithiasis is challenging because of the lack of anatomic landmarks.We reviewed our prospectively collected database from 1994 to 2006 for all patients requiring surgical treatment for obstructive complications associated with ureterosigmoidostomy.Our analysis revealed 3 patients (mean age 46 years; 2 men and 1 woman). All 3 patients had undergone ureterosigmoidostomy as a component of bladder exstrophy management. All patients presented with renal failure due to obstruction and required antegrade endoscopic management. Two patients had anastomotic strictures and one had obstructive urolithiasis. One patient in whom the stricture was judged to be chronic was treated with an endoureterotomy and Acucise balloon. The second patient, who had an acute obstruction after colonoscopic biopsy of his anastomosis, was treated with antegrade balloon dilation. Both patients had stents placed across the anastomosis for 6 weeks postoperatively. Despite reflux of stool into the collecting system, neither patient manifested with local or systemic signs of infection. The patient with urolithiasis required antegrade basket stone extraction.Obstructive complications after ureterosigmoidostomy should be managed using antegrade endoscopic techniques.
