Colocalicostomy. A solution to an obliterated renal pelvis.

A thirty-nine-year-old paraplegic with an ileal conduit urinary diversion and long ureteral strictures bilaterally required urinary tract reconstruction to establish effective internal drainage. Reported techniques proved infeasible. Therefore, the right kidney with its small intrarenal pelvis was opened by anatrophic nephrotomy and anastomosed to a segment of transverse colon in two layers. The left kidney could not be anastomosed directly to the colon segment, so it was anastomosed end-to-side to an isolated jejunal segment. Colocalicostomy should be considered in the repair of an obliterated renal pelvis or an isolated, obstructed lower-pole calix.
