Abstract
SUMMARY: One hundred and five cases of vesical diverticulum are analysed. The ætiology is discussed, and it is suggested that urethral obstruction and bladder‐wall hypertrophy exist in all cases. It is suggested that congenital bladder‐neck obstruction is the obstructing factor. The mechanics of formation and enlargement of a diverticulum are considered, and it is suggested that the pouch always enlarges and remains within the layers of the bladder wall. The indications for treatment are discussed, and it is suggested that the presence of residual urine in the diverticulum is the only reliable indication for operation. Operative details are considered and an alternative and simpler operation is described. Urinary infection, calculus. carcinoma of the bladder and renal failure are considered as to their effect on treatment.
