Bilateral ureteric obstruction caused by benign pelvic lipomatosis

A second case of bilateral ureteric obstruction owing to diffuse pelvic lipomatosis is reported. The clinical features and possible aetiological factors are discussed. The condition may be mistaken for a pelvic neoplasm due to high fixation of the bladder and colon, but it is felt that the diagnosis can be made on the basis of characteristic radiological findings. Surgical intervention is unsuccessful in replacing the bladder and colon to their normal positions but may be necessary for relief of obstruction.
