Abstract): INTRODUCTION: Application of constriction over penis by means of various objects for autoerotic purpose is a practice that may lead to dangerous consequences. A large variety of objects have been used for this purpose leading to a spectrum of complications. Management of such cases poses a great challenge to the treating surgeon, as it often requires teamwork involving not only doctors but also technical experts from engineering department. We report a case where a man presented with acute retention of urine with two metallic rings over his penis. CASE REPORT: A 50 years old man presented to the surgical emergency ward with complaint of acute retention of urine. He had pushed two metallic rings over his penis about two hours back in a bid to get sexual pleasure while he was under influence of alcohol. The rings later got impacted over the penis because of congestion of distal part of penis. Soon the patient developed the complaint of mild pain and swelling of penis and inability to pass urine and was brought to the hospital. The physical exam revealed that the part of penis distal to the rings was congested, swollen and slightly discolored. We started with urinary bladder emptying by putting a wide bore needle suprapubically and connecting it to a urobag through a drip set. Penile block was given. Blood was then aspirated from both corpora cavernosa distal to the rings and the rings were manipulated after generous application of lubricant jelly. This way, rings could be moved almost up to corona glandis obstructed only by a band of edematous skin. Now multiple needle punctures were given in this skin and the area was kept compressed for a while using a tape-gauze wrapped tightly over it. On removing the gauze, rings could be moved up to corona. Now the distal ring was placed with its wide stone bearing part against the ventral aspect of glans. Glans was then decongested by means of needle punctures and digital compression. Ring was rotated with traction while glans was compressed to negotiate through it. The attempt was successful and both rings were removed in this fashion. The post operative course was uneventful. CONCLUSIONS: Aspiration and puncture technique facilitates the removal of constricting objects from the penis. This technique is safe and does not require sophisticated equipment.
