A 54 year old man was found to have a simple ureterocele with a dilated ureter. Ultrasonography demonstrated the ureterocele as an echo-free structure at the base of the bladder without involvement of the bladder wall. The course of the dilated ureter and its entrance into the bladder were clearly defined.

The massively dilated ureter is a major therapeutic challenge that faces the pediatric urologist. In those instances when more conservative measures, such as control of infection or correction of the primary pathology, have failed or are likely to fail surgical treatment must be directed to the massively dilated ureter itself. The goals of reconstructive procedures are the elimination of residual urine, effective ureteral peristalsis, and efficient and/or urgent urinary drainage. We encountered these clinical settings in 244 children with 366 massively dilated ureters from 1965 through 1974. The underlying pathologic processes included primary megaureter, refluxing megaureter, posterior urethral valves, ureteral duplication with upper role ectopic ureterocele or lower pole refluxing megaureter, simple ureterocele, ureterovesical junction obstruction, neurogenic vesical dysfunction, prune belly syndrome and acquired (iatrogenic) megaureter. The results of several reconstructive techniques are reviewed according to the excretory urogram, cystogram, renal function studies and the presence or absence of urinary infection. Analysis of the results with respect to the underlying pathologic entity responsible for the massively dilated ureter indicates that the etiology is a crucial factor in determining whether surgical treatment should be recommended and the type of surgical treatment that will most likely be successful.

The problem of a duplex collecting system associated with an obstructed ectopic ureter or ureterocele is common in pediatric urology. Four such patients were studied by gray scale ultrasound which was useful in demonstrating the dilated upper pole collecting system as well as an ectopic ureter and a ureterocele. Although the diagnosis of a nonfunctioning upper pole unit in a duplex kidney is usually suggested by the urogram, ultrasound provides a noninvasive means of confirmation which is independant of function. Further, ultrasound-guided puncture with antegrade pyelography demonstrates the course of the ectopic ureter, thus providing a more complete preoperative evaluation.

Three children with ectopic ureteroceles were examined with ultrasound, intravenous urography and cystography. In all cases the ultrasound studies outlined the ectopic ureterocele within the fluid-filled bladder and in one case added additional information regarding the non-functional portion of the duplication and its ureter.

A personal experience in the management of 73 ureterocele cases during the last 17 years and points of technical importance in the correction of this sometimes complex problem are described. Small adult-type ureteroceles are best resected, reimplanting the ureter, since simple unroofing can cause reflux. The infant-type ureterocele with a duplex collecting system requires individualization according to the status of the patient. In ectopic ureterocele cases the bladder outlet often requires repair. The spectrum of management for this group of problems is shown by representative cases.

Report of a case of prolapse of the lower end of the ureter into the bladder. Observed in a 11 year-old boy with a history of recurrent urinary infection. The bladder deformity was seen as a non-opaque filling defect which possibly ressembles the shadow of a simple ureterocele. The child required resection of the prolapsed segment and ureteral reimplantation using the combined suprahiatal and infrahiatal routes.

Behind the typical signs of a staghorn calculus of a kidney and a ureterocele with calculi in x-ray a transitional cell carcinoma of the kidney and the whole ureter was found. The nonfunction of the organ was thought to be due to pyonephrosis. Four other cases reported in the literature are discussed.

Three cases involving developmental anomalies of mesonephric duct derivatives were examined by computed tomography and ultrasonography. Cases included an ectopic ureter inserting into a cystic seminal vesicle, an ectopic ureterocele, and agenesis of the seminal vesicle and vas deferens. Computed tomography and ultrasonography were valuable noninvasive methods, supplementing standard radiographic techniques, for evaluating these anomalies.

Ipsilateral ureteroureterostomy near the bladder (end-to-side anastomosis) for treatment of single ureteral disease in patients with complete ureteral duplication has been performed in 16 patients during the last 8 years. The operative technique, indications, results, followup and complications are presented. Reflux in the lower segment ureter was treated in 13 patients and upper segment ectopia or ureterocele was managed in 3 patients with this operative procedure. This operative technique is simpler and safer than reimplantation of both ureters into the bladder. Because no dissection of the bladder wall is needed there is less risk of injury to the pelvic viscera and vasculature. The chance of success in correcting reflux appears better than with reimplantation of both ureters into the bladder. Long-term followup has shown few complications and no repeat operations were needed in this series. The small stump of the diseased ureter left behind near the bladder caused no serious problems.

Experience with 20 simple ureteroceles in 18 children is reviewed. In most cases hydroureteronephrosis of various grades of severity was present. In 5 cases the related kidney was non-functioning. The ureterocele generally is seen on excretory urography, either as a positive cobra-head dilatation or as a negative filling defect in the cystogram when renal function is impaired. Cystoscopy is diagnostic but confusion may occur when a lax ureterocele is compressed and emptied or even everted by a high intravesical pressure. Expectant management is warranted in the absence of upper tract dilatation but operative intervention is needed in most cases. Nephroureterectomy may be unavoidable if the kidney is afunctional. Simple unroofing or incision of the ureterocele is followed by vesicoureteral reflux and ascending infection. The preferred technique is total excision of the ureterocele and reimplantation of the ureter into the bladder by an antireflux technique.
