Neurofibromatous ureteral obstruction relieved by sigmoid conduit cystoplasty

Neurofibromatosis is a neural disease of hereditary nature affecting both sexes of all races. Visceral and central nervous system involvement can cause serious interference with normal function of affected structures. Under these circumstances, lifelong observation and individualized treatment of the patient are essential to proper management. This report is an account of nearly 2 decades of conservative management of neurofibromatosis of the pelvis in a young woman. Progressive, bilateral ureteral obstruction developed but normal function of the urinary tract has been maintained for the last 10 years with a sigmoid conduit cystoplasty. It is anticipated that continued progression of the disease will require cutaneous transfer of the sigmoid conduit. Also, a colostomy might become necessary because of recent evidence of rectal obstruction noted on computed tomography.
