An unmarried 35 years old male, who took 25mg sildenafil daily for 8 days followed by 12.5 mg daily for 4 days, with consultation with a local chemist for nocturnal emission developed priapism. He presented to an urologist after 72 hours where a corporal wash and distal shunt was tried but it did not give any relief to the patient. He had no other identified contributing factors for priapism. A proximal caverno-spongiosal shunting (Quackels cavernoso-spongiosal shunts) was done which subsequently relieved his symptoms. To our knowledge this is the first reported case of priapism resulting from supposedly safe doses of sildenafil in a healthy individual. Distal shunts are associated with high failure rates which may warrant a more proximal shunt. Even when seen after a considerable time a shunt may be useful. After the delayed surgery, relief of pain without complete detumesence suggests a role for watch-full waiting.
