Sacral dysgenesis associated with occult spinal dysraphism causing neurogenic bladder dysfunction.

A case of a neurogenic bladder in a 20-year-old man is described. The patient had difficulty in voiding and incontinence, with a history of several urinary infections. Misdiagnoses included stricture and posterior urethral valves. Early treatment included urethral dilation, a transurethral resection and a left ureteral implantation. Throughout this time the neurological examinations were essentially normal. Final diagnosis was sacral dysgenesis with associated occult spinal dysraphism, after the discovery of a small pock mark over the sacrum and an abnormal pelvic x-ray. Urinary diversion was done.
