Inguinoscrotal Hernia of the Urinary Bladder

Abstract

Inguinal bladder hernia (IBH) is a rare clinical condition that may present as scrotal swelling. Most patients are asymptomatic and found incidentally at the time of herniorrhaphy. IBH continues to pose a challenge to surgeons before, during, and even after herniorrhaphy. This case report aims to describe the case of the incarcerated right inguinal hernia containing the small bowel and the urinary bladder herniation. An 81-year-old male presented to the emergency department with complaints of abdominal pain, distension, and swelling in the right groin. Physical examination was remarkable for incarcerated right inguinal hernia with tenderness to palpation. A CT scan demonstrated a right inguinal hernia containing a small bowel. The urinary bladder was noted to be adherent to the hernia sac. The hernia sac and urinary bladder were reduced, and Lichtenstein tension-free hernia repair was performed. The postoperative course was uneventful without any complications. IBHs are uncommon. Unrecognized bladder hernias can cause bladder injury during surgery. It is particularly common in individuals with long-standing hernias and should be anticipated during surgery. High-risk patients including obese, older men, who have urinary symptoms that need further evaluation with a CT scan, ultrasound, or cystography to prevent iatrogenic injury and complications. Management consists of reduction or resection of the herniated bladder followed by hernia repair.
