154 Complete Inguinal Bladder Hernia Causing Acute Obstruction of Right Upper Urinary Tract

Abstract

Abstract Case Summary An 86-year-old male nursing home resident presented with increasing confusion and was initially treated for catheter-associated urinary tract infection. CT scan demonstrated acute acalculous cholecystitis and complete inguinal bladder hernia with compression of right vesico-ureteric junction leading to acute obstructive renal failure. Percutaneous cholecystostomy and percutaneous nephrostomy were attempted but were not possible due to patient non-compliance. Patient improved with conservative management. Discussion Bladder involvement in inguinal herniae is rare with most cases being identified at the time of hernia repair and there is a 17% risk of intra-operative bladder injury. Key risk factors include increasing age, male gender, lower urinary tract symptoms and previous hernia repair. Percutaneous nephrostomy followed by inguinal hernia repair is the treatment of choice for most patients. Clinicians should aim to make the diagnosis of inguinal bladder hernia pre-operatively to reduce risk of intra-operative bladder injury during hernia repair. Acute acalculous cholecystitis tends to occur in critically ill patients and is a marker of poor prognosis.
