MP41-08 URETERAL SUBSTITUTION WITH INTESTINAL SEGMENTS

Ureteral Substitution Using Appendix for a Ureteral Defect Caused by a Retroperitoneal Rhabdomyosarcoma in a Child

A 7-year-old boy was diagnosed with a recurrent embryonal rhabdomyosarcoma in the retroperitoneum. After resection of the mass, direct end-to-end anastomosis of the ureter was not possible owing to the length of the resected segment. Accordingly, we performed ureteral substitution by using the appendix to repair the ureteral defect.

Ureteral Reconstruction With Bowel Segments: Experience With Eight Patients in a Single Institute

PURPOSE Although replacement of the ureter with a bowel segment is indicated for large ureteral defects, it is still a challenging technique for urologists. We present our experience and outcome of ureteral reconstruction using bowel segments. MATERIALS AND METHODS Ureteral reconstruction with bowel segments was performed in eight patients in our institute between 1969 and 2009. We investigat...

Unusual stent after ureteral substitution. A first case

BACKGROUND To the best of our knowledge this is the first case where a Silastic drain is used in ureteral surgery instead of a common urological stent. Patients coming from other institutions, especially in peripheral areas, can be treated with non conventional devices and if traditional imaging is inconclusive, computed tomography (CT) can provide valuable information to make the right diagnos...

The Dangers of Excluded Intestinal Segments

Chemical Carcinogenesis in Transposed Intestinal Segments 1

A research model has been devised to assist in an assessment of the relative susceptibility of small bowel and colonie mucosa to potential intestinal carcinogens, and an application of this model to azoxymethane is reported. Intestinal transpositions were performed on Sprague-Dawley rats. In one group, segments of small intestine were transposed to the ascending and descending colon and, in ano...
