Diabetic neuropathic bladder associated with clinical features of iliofemoral venous thrombosis

A 60-year-old female diabetic patient with autonomic neuropathy gradually developed a warm swollen left leg over a period of 12 days. She was found to have chronic retention of urine due to a neuropathic bladder. Venography did not reveal thrombus but showed compression of the ipsilateral external iliac vein by the bladder. No other cause for her warm swollen leg was found. Following the introduction of a bladder catheter, her leg gradually returned to normal.
