Rare etiology of obstructive uropathy: pelvic lipomatosis.

We present a case of a 32-year-old hypertensive and obese male who had bilateral obstructive uropathy, and who was diagnosed as having pelvic lipomatosis on the basis of clinicoradiological findings. Cystoscopy and biopsy revealed cystitis cystica. He was successfully managed with bilateral extravesical modified Lich-Gregoir ureteric reimplantation by intraperitoneal approach. At 5 months follow-up, the patient had normal serum creatinine and was clinically asymptomatic.
