Abstract

Two male patients presented with urinary retention 6 and 8 months after a stroke. On urodynamic investigation, both had impaired detrusor function and bladder neck obstruction, and 1 had unrelaxing distal urethral sphincter. Abnormalities of ocular movement were present. Magnetic resonance imaging revealed a widespread lesion of the dorsal tegmentum of the pons. Transurethral resection and incision of the prostate enabled them to void without significant residual urine. Pontine hemorrhage may cause neurogenic vesicourethral dysfunction because the pontine micturition center is located in the dorsolateral tegmentum of the rostral pons.
