Bladder perforation caused by long-term catheterization misdiagnosed as digestive tract perforation: A case report

Spontaneous bladder rupture is relatively rare, and common causes of spontaneous bladder rupture include bladder diverticulum, neurogenic bladder dysfunction, gonorrhea infection, pelvic radiotherapy, etc. Urinary bladder perforation caused by urinary catheterization mostly occurs during the intubation process.

Here, we describe an 83-year-old male who was admitted with 26 h of middle and upper abdominal pain and a history of long-term catheterization. Physical examination and computed tomography of the abdomen supported the diagnosis of diffuse peritonitis, most likely from a perforated digestive tract organ. Laparoscopic exploration revealed a possible digestive tract perforation. Finally, a perforation of approximately 5 mm in diameter was found in the bladder wall during laparotomy. After reviewing the patient's previous medical records, we found that 1 year prior the patient underwent an ultrasound examination showing that the end of the catheter was embedded into the mucosal layer of the bladder. Therefore, the bladder perforation in this patient may have been caused by the chronic compression of the urinary catheter against the bladder wall.

For patients with long-term indwelling catheters, there is a possibility of bladder perforation, which needs to be dealt with quickly.
