title: Longitudinal ureteral split for retroperitoneal fibrosis with ureteral involvement.
abstract: Idiopathic retroperitoneal fibrosis may rarely invade the ureteral wall, thereby rendering the attempt to perform classical ureterolysis futile. Possibilities for surgical correction include resection with end-to-end anastomosis, utilization of a spiral strip of ureter, small bowel substitution, iatrogenic nephroptosis or longitudinal incision of the involved ureter down to the mucosa. Two patients treated using the latter technique have been followed for 7 months and 132 months without recurrence of the obstructive process. The surgeon, when treating idiopathic retroperitoneal fibrosis, must be prepared to treat intrinsic ureteral involvement using the most appropriate surgical technique.
