Syncope in a patient with giant bladder diverticulum

Abstract

Syncope is common in clinical practice, but the cause is often difficult to diagnose. We report a 75-yearold man who was referred to the emergency department because of syncope after an urgent sensation of urinating during jogging. He was finally diagnosed as having a giant bladder diverticulum due to prostatic hyperplasia accompanied by neurally mediated syncope. Excessive urinary retention is a possible cause of not only giant bladder diverticula but also syncope due to vagal enhancement. © 2012 The Japanese Society of Internal Medicine.
