Successful conservative management of a spontaneous intraperitoneal rupture of bladder diverticulum in a critical patient: A case report. A CARE-compliant article

Abstract

Rationale:A spontaneous rupture of the bladder diverticulum in an adult patient is extremely rare. The recommended treatment is surgery. However, some cases can be successfully treated with urinary catheterization, antibiotics, and/or percutaneous peritoneal drainage. In this case report, a spontaneous rupture of the bladder diverticulum was successfully treated non-surgically because it was deemed too risky for surgical intervention, such as non-ST segment elevation myocardial infarction (NSTEMI).Patient concerns:A 76-year-old man presented with abdominal pain, distention, diarrhea, and oliguria for 3 days and hypotension for 1 day with no history of trauma. The patient showed direct and rebound tenderness in the lower abdomen. Computed tomography revealed an intraperitoneal bladder rupture associated with the bladder diverticula. Electrocardiography, echocardiography, and elevated cardiac enzyme suggested NSTEMI.Diagnoses:A spontaneous rupture of the bladder diverticulum, NSTEMI, and suspected sepsis due to gastroenteritis or urinary infection.Interventions:The patient was treated conservatively with urinary catheterization and antibiotics for a bladder rupture and an infection. Percutaneous transluminal coronary angioplasty was performed for NSTEMI.Outcomes:The patient fully recovered without complications on hospitalization day 13.Lessons:Conservative management might be an alternative for a spontaneous intraperitoneal bladder rupture in some cases. However, close observation is required, and surgical intervention is the first option for a spontaneous intraperitoneal rupture of the bladder diverticulum.
