Pan-caliceal ileoneocystostomy--a new operation for intrapelvic tuberculotic strictures of the renal pelvis.

Intrarenal scarring with stricture formation is common in late cases of renal tuberculosis and has caused more loss of renal function than direct involvement by tuberculosis. The classical treatment of this condition is heminephrectomy for early cases and total nephrectomy for late cases. However, these destructive procedures are far from satisfactory. We describe a new operation, pan-caliceal ileoneocystostomy, that aims at draining the entire caliceal system into an ileal ureter, which thereby relieves the obstruction. Good results were obtained in 2 cases. This procedure also is applicable to cases of intrarenal scarring with stricture formation owing to other causes.
