Ureterocele.

In conclusion, the diagnosis and management of the ureterocele, simple or ectopic, require careful and thorough preoperative evaluation, culminating in a carefully planned and precisely done operative procedure. An error of omission can be a catastrophe. The choice of surgical approach is controversial but should be one with few potential complications. An awareness and understanding of the potential complications of ureterocele surgery are mandatory and should aid in their prevention. To avoid postoperative complications related to the retained ureteral stump, for ectopic ureteroceles I prefer removal of the entire dilated upper-pole ureter and ureterocele regardless of the manner in which the upper-pole parenchyma is managed. As noted, infants and small children with large ectopic ureteroceles may be approached entirely extravesically, excising the dilated ectopic ureter to the detrusor hiatus.
