Abstract
A 72-year-old man presented with urinary retention, weight loss, haematuria and severe acute kidney injury. He had never before been admitted to hospital and his past medical history included only an inguinal hernia. On examination, he appeared uraemic and had a right-sided painful hernia. A three-way catheter was inserted, bladder washouts performed and irrigation started. An ultrasound showed severe bilateral hydronephrosis and a 'thickened bladder' and this was thought to be obstructive uropathy secondary to bladder cancer. Twenty-four hours later his hernia doubled in diameter, became incarcerated and a CT of the abdomen and pelvis showed an inguinal hernia of both bladder and bowel, with the catheter tip inside the bladder hernia. He was taken to theatres and an open mesh repair was performed with a rigid cystoscopy to assist in locating and reducing the bladder. He required intensive care and dialysis postoperatively and remains on regular dialysis following discharge.
