Abstract:
Penile rings have been used to help sustain erection and enhance sexual pleasure for centuries. Constriction of the penis reduces the outflow of blood from the cavernosal tissue. However, if left for an extended time period, a condition called penile ring entrapment can occur. This may result in severe edema, gangrene, necrosis, and even penile amputation. Penile ring entrapment is a very rare condition; complete urinary obstruction with concomitant bladder rupture as a result renders this case even more extraordinary. We discuss our experience in the management of a 64-year-old man, who presented with altered mental status and inability to urinate, found to have penile ring entrapment and intraperitoneal bladder rupture. Removal of the constricting ring was performed in the ED, and bladder injury and penile necrosis were subsequently repaired with robot-assisted laparoscopic cystorrhaphy, penectomy, and perineal urethrostomy.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
