Abstract

OBJECTIVE:

To report 10 years' experience with ileal ureteric replacement as a last resort in complex reconstruction of the urinary tract.

PATIENTS AND METHODS:

From March 1991 to February 2002 ileal segments were used for partial or total substitution of the ureter in 43 patients (mean age 45.6 years) with structural or functional ureteric loss secondary to irradiation, surgical complications or various other pathological conditions. Ileum was either implanted into the native urinary bladder (in 14) or an intestinal reservoir (in 29). In the latter group the technique was used at the time of primary urinary diversion in eight, in a secondary approach for treating early or late complications in nine and in undiversion or conversion procedures in 12. The ileal ureter was implanted into the urinary reservoir using a serous-lined extramural tunnel or distal intussusception for reflux prevention (in 31). All patients were followed prospectively according to a standardized protocol.

RESULTS:

There were no perioperative deaths; the mean (range) follow-up was 40.8 (1.5-109.5) months. In 41 patients with dilatation of the upper urinary tract before surgery there was a significant improvement radiographically in 34, no change in five and deterioration in two. The serum creatinine level decreased or remained stable in all. Reflux occurred in the 12 cases without and in three with an antireflux mechanism. Shortening of an elongated kinking ileal ureter became necessary because of recurrent severe metabolic acidosis and mucus obstruction in two; in one case mucus obstruction was treated endoscopically. There was pyelonephritis only in three patients with refluxing implantation into an intestinal reservoir.

CONCLUSION:

Ileal ureteric replacement is a safe and reliable last resort even in difficult cases. Whenever feasible, antirefluxing implantation into intestinal urinary reservoirs is recommended.
