Congenital bladder diverticulum – a rare adult presentation

Congenital bladder diverticula usually present during childhood. They are solitary and present with infection, haematuria and abdominal pain. They are associated with a smooth walled bladder without bladder outlet obstruction. An adult male presented with voiding symptoms and lower abdominal pain. On evaluation he had a grossly distended bladder extending from the hypogastrium up to the right hypochondrium. Investigations revealed a large bladder diverticulum and left hydronephrosis with a non-functioning left kidney. Left nephroureterectomy and diverticulectomy were carried out. We report this case because of its unusual adult presentation.
