  • Title: Ileal ureteral substitution in reconstructive urological surgery: is an antireflux procedure necessary?
    Author: Waldner M, Hertle L, Roth S.
    Journal: J Urol; 1999 Aug; 162(2):323-6. PubMed ID: 10411030.
    Abstract:
    PURPOSE: Whether antireflux implantation techniques are necessary in adults who undergo ileal ureteral substitution is controversial. We prospectively evaluated the correlation between reflux and renal function in 19 patients who underwent ileal ureteral substitution with no antireflux implantation technique. MATERIALS AND METHODS: Followup included clinical evaluation, serum creatinine, blood gasses, excretory urogram, cystogram and dynamic selective renographic clearance on technetium mercaptotriglycine renal scans. All patients were followed for a minimum of 4 years except 2 who died 26 and 43 months postoperatively. Mean followup was 57 months (range 48 to 72). RESULTS: Despite reflux, renal scans indicated a significant increase in renal function in all patients. Vesico-ileal reflux was present in 9 cases and reflux in the renal pelvis occurred in only 3. Reflux occurred in only 3 of 10 patients with ileal segments longer than 15 cm., and did not reach the renal pelvis. CONCLUSIONS: Reflux appears to have no detrimental effect on renal function in adults with ileal ureters and, therefore, an antireflux procedure is unnecessary. In addition, an ileal segment longer than 15 cm. appears to safeguard the renal pelvis against visible reflux stemming from pro-grade intestinal peristalsis.
