Applications of Ureterosigmoidostomy in Bladder Exstrophy
1999
Until 1994, 95 patients with bladder exstrophy and 20 with incontinent epispadias were operated upon at our department. During the last years more and more exstrophycripples were referred to our institution after primary treatment elsewhere. Thus a total of 56 of the 104 patients had a secondary treatment after failure or unsatisfactory treatment. In contrast to many other institutions, our standard procedure was primary ureterosigmoidostomy and, since 1990 it is completely replaced by a modification of it, the sigma rectum pouch (Mainz Pouch II). After failed primary bladder closure and in patients with short or pathological ureters or insufficient anal sphincter function, we prefer an ile…
Confocal Laser Endomicroscopy and Chromoendoscopy - A New Option of Surveillance in Patients with Ureterosigmoidostomy or Rectosigmoid Pouch
2010
Purpose In patients with bladder exstrophy-epispadias-complex (BEEC) or in selected patients with bladder loss for other reasons, ureterosigmoidostomy (USIG) & rectosigmoid pouch (Mainz Pouch (MZP) II) has been used at our institution. This diversion carries a lifelong risk for secondary malignancies. Therefore annual colonoscopy is recommended. Identification of potentially malignant structures can be challenging, and biopsies are taken in doubt, with the risk of injuring the ureterocolic implantation site. Using confocal laser endomicroscopy (CLE) and chromoendoscopy, the uretero-intestinal anastomosis is better visualized compared to conventional colonoscopy, and target biopsies could be…
