“…Those studies recommended the use of reconfigured colon segments outside of the radiation portal. Several studies have demonstrated that a prior history of abdominal or pelvic radiation should not serve as the sole determining factor for the selection of the bowel segment utilized during urinary diversion because there is evidence that, in most patients, the complication rate is low with use of the ileum [13,22]. In the present study, we reconstructed the ureter by using the ileum after radiation therapy in two of four patients who needed the additional surgical procedure.…”

“…The merits of the ileal segment are its mobility, small diameter, and constant blood supply [3]. Contraindications for the ileal ureter are inflammatory bowel disease, an irradiated bowel, bladder neck obstruction, neurogenic bladder, renal insufficiency with a serum creatinine concentration of greater than 2 mg/dL, and hepatic dysfunction [5,13]. A colon segment has different merits that the ileal segment does not have [11].…”

PurposeAlthough 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 MethodsUreteral reconstruction with bowel segments was performed in eight patients in our institute between 1969 and 2009. We investigated the position and length of the ureteral defect and methods of reconstruction as well as the patients' backgrounds, postoperative complications, and clinical outcomes.ResultsFive patients underwent ureteral replacement with isolated ileal segments alone. In one patient, the ureter was reconstructed by using the Yang-Monti procedure with the ileum. A colon segment was used in two patients who required bladder augmentation for tuberculous contracted bladder at the same time. Metabolic acidosis occurred in three patients having a solitary kidney and the ureter had to be replaced by a relatively long intestinal segment. Two patients who received preoperative radiation therapy were required to undergo additional operations. Long-term cancer-free survival was achieved in one patient who underwent ileal substitution for low-grade renal pelvic cancer.ConclusionsAlthough ureteral replacement with a bowel segment is a challenging and useful procedure, attention must be paid to the possibility of metabolic acidosis, which is likely to occur in patients having a solitary kidney with renal insufficiency or in patients requiring a long intestinal segment for reconstruction. In addition, preoperative radiation therapy for the pelvic organs may cause postoperative complications.

“…Desde la primera descripción de reemplazo ureteral se han propuesto técnicas con apéndice cecal 8 , vasos sanguíneos, trompa de Falopio, peritoneo y material sintético, con escasos resultados 9 . El intestino delgado es el segmento más utilizado, sin embargo, se han descrito experiencias con colon 10 .…”

Bilateral ileal ureteral replacementIntroduction: Ureteral replacement by a loop of defunctionalized ileum was described more than 2 centuries ago and continues to be a therapeutic option at present. This series describes the technique of bilateral ureteral replacement with ileum. Aim: To report 4 cases of bilateral ileal ureteral replacement performed at our institution, its indications, the surgical technique, complications, and a review of the literature. Material and Method: We report 4 cases of extensive bilateral ureteral injury of different etiologies, whose treatment with curative intent was to replace the damaged ureter with a isoperistaltic small bowel segment. Results: The surgical technique used was standard in all cases. There were no intraoperative complications and only one patient had hyperchloremic acidosis. No patient has shown loss of renal function in the long-term follow up. Conclusion: Is an effective therapeutic, safe and reproducible technique to replacement of major bilateral ureteral injuries, independent of the original cause.

“…Autologous tissues such as small bowel, appendix, fallopian tube, stomach, and colon have been used as substitute for a damaged ureter [2][3][4][5][6][7][8][9][10]. Synthetic materials have been developed and failed to gain wide acceptance [5].…”
