Penile strangulation: report of two unusual cases.

We report two cases of penile strangulation that presented to our emergency department. In the first case, a 60-year-old man, the object of strangulation was a metallic ring that was extricated using an orthopaedic cutter in the operating theatre. The patient recovered uneventfully. In the second case, a 77-year-old man, the object of strangulation was a plastic bottle, which was extricated using surgical instruments in the emergency department, but the patient subsequently developed postobstructive diuresis. The first case illustrates the difficulty that may be encountered in this delicate yet urgent situation, while the second case reports a rare complication.
