Diverticula of the Urinary Bladder

Author and Disclosure Information

Abstract

Diverticula of various hollow organs of the body are frequently encountered. They may be present without causing any outstanding symptoms, but that they do often cause symptoms and impairment of health is well attested by the many reports which have appeared in the literature of diverticula of the gastro-intestinal tract. In many cases, however, their presence is not suspected and the symptoms produced by them are supposed to be due to some other condition for which treatment is instituted. This is true also of diverticula of the urinary bladder.

The most common location of diverticula in the urinary bladder is in the lateral wall near the ureters. It is interesting to note that in the cases cited in the literature, as in our series, more were proximal to the left than to the right ureter — a fact, however, that seems to have no especial significance. In 62.1 per cent of our cases the diverticulum was in the lateral wall. In 21.2 per cent it was on the posterior wall; rarely in the dome and still less frequently in the trigone.

Diverticula may be single or multiple. In our series a single diverticulum was present in 63 per cent, two diverticula were demonstrated in 14.9 per cent, and there were more than two in 22 per cent.

The causative factors of diverticula of the gastro-intestinal and of the urinary tract are probably fundamentally identical. They are no doubt due to some congenital defect which, becoming aggravated under certain conditions, produces a. . .
