Bladder diverticulum, Voiding dysfunction, Internal herniation, Intestinal obstruction, Management


Urinary bladder diverticula can be congenital or acquired, and the latter tends to occur in older men and results from urinary obstruction. Primary bladder diverticula are congenital, smooth walled, solitary in nature and rarely diagnosed in adults. An internal hernia (IH) is a protrusion of intestines or other abdominal organs through a normal or abnormal orifice in the peritoneum or mesentery, occasionally leading to strangulation or incarceration. Internal hernias (IH) are rare causes of acute abdomen and intestinal obstruction in adults. Here we present a case report detailing the authors' surgical experience with inverted bladder diverticulum, presenting as internal hernia with sigmoid colon herniating through it, with features of acute intestinal obstruction and urinary dysfunction.
