Diverticulum of bladder is a condition where the bladder lining protrudes through a weak or defective part of the bladder wall, forming a pouch or bulge that connects to the bladder lumen.

Most often, bladder diverticula have no direct signs. They are found while looking for causes of other urinary problems.

Bladder diverticula are often asymptomatic, but there can be urinary related symptoms. Some of the symptoms include: Urinary retention (inability to urinate). Urinary tract infection. Blood in the urine. Bladder diverticula are often diagnosed on imaging studies like a CT scan or ultrasound.

Bladder diverticula can be found with an x-ray test of the bladder. The test is done by filling the bladder with a dye that shows up well in x-rays (called a "contrast") and taking pictures. Your health care provider may also look into your bladder with a cystoscope, a long, thin telescope with a light at the end.

Bladder diverticula don't always need to be treated if they're not causing any problems. Diverticula caused by a block in the bladder are treated by taking out the block and maybe the diverticulum, as well. The surgery can be done by open surgery or through small tubes fed inside the bladder. A robot may be used to help with the surgery.

Some rare risks of diverticulum surgery are:

• damage to the intestines or ureters (the tubes that carry urine from the kidneys)

• urine leaking from the bladder after surgery

• infection

• Rate as voiding dysfunction or urinary tract infection, whichever is predominant.
