Glomerular filtration rate up to 10 years after urinary diversion of different types. A comparative study of ileal and colonic conduit, refluxing and antirefluxing ureteral anastomosis and continent caecal reservoir.

To evaluate the influence of conduit type (ileal or colonic) and method of ureterointestinal anastomosis (refluxing or antirefluxing) on renal function in patients with urinary diversion, a prospective randomized trial was conducted in 1977-1984. During these years urinary diversion via a continent caecal reservoir emerged as an alternative to conduit diversion at our hospital, and these patients with continent reservoir were also included in the study. Total and separate glomerular filtration rate (GFR) were measured, the latter with scintillation camera renography, preoperatively and at follow-up in 70 patients. Measurements 2-10 years postoperatively showed slight to moderate decrease of GFR in all groups, with no significant difference between values according to conduit type or caecal reservoir or between refluxing and antirefluxing ureterointestinal anastomosis. Almost all of the anastomotic strictures involved the ureter that had been brought beneath the sigmoid mesentery, indicating that ischemia secondary to extensive ureteral mobilization is a likely cause of stricture in these cases.
