Acute ureteral obstruction by lymphoceles following cadaver kidney transplantation.

Acute ureteral obstruction caused by perinephric and pelvic lymphoceles developed after the transplantation of a cadaver kidney in a patient who had been on chronic hemodialysis for two years. The patient was readmitted two months after the transplantation and found to have three large cystic masses in the pelvic region, which were successfully drained. Early diagnosis and aggressive surgical treatment of post-transplantation lymphoceles are essential, if the function of the transplanted kidney is to be preserved.
