    Abstract:
    We report on 47 patients, surveyed and treated by us, diagnosed of primary vesical diverticula, having thus excluded all those secondary to lower obstructive anomalies, such as urethral valves and neurogenic bladder. Only seven out of the 47 patients were females: two of them had a iatrogenic cause and the remainder were of small size and associated with vesicoureteral reflux. All the cases have been documented by means of an intravenous pyelography (IVP), an excretory cystogram and a voiding cystourethrogram (VCUG). Many diverticula may go unnoticed when screened by IVP, whereas the cystogram and preferentially the VCUG are a 100 for 100 diagnostic. A 45 for 100 of these children (22 cases) had an attendant reflux and 23 for 100 (11 cases) had some other concomitant renal disease. Three further cases were iatrogenic, as a result of the methods employed for antireflux ureteral reimplantation. A 77 for 100 of the patients had urinary tract infection demonstrated by a urinary sediment and a positive culture. Surgery was performed on 34 patients, the indication being made on the basis of the big size of the diverticulum, its clinical repercussion, or because of its association with vesicoureteral reflux or any other kidney malformation. We employ an intravesical approach for the small diverticula with attendant reflux, but for resection of the sizeable ones, irrespective of the existence of reflux, we prefer the combined extra and intravesical approach, which allows a most accurate extravesical dissection, as well as the recognition and control of the ureter and the deferes duct, structures both that are usually anatomically distorted.
