Abstract
Surgical reconstruction for ureteral obstruction is necessary in 1 to 10 per cent of renal transplants. On an acute basis edema, ischemia, lymphocele and hematoma formation cause ureteral obstruction. Chronic etiologies include ureterovesical obstruction and retroperitoneal or ureteral fibrosis. Options for repair are myriad and include repeat ureteral reimplantation, pyeloureterostomy, ureteroureterostomy, pyelocystostomy and calycovesicostomy. We report on the desirability of calycovesicostomy as a last resort option for total ureteral obstruction after renal transplantation.
