Nine patients with ectopic ureterocele, complete duplication, and nonvisualization of the upper renal segment are presented. All were managed with heminephrectomy and partial ureterectomy only. The procedure immediately controlled urosepsis, and ultimately was successful in the management of associated reflux. Excision of ureterocele and reimplantation of the ipsilateral ureter was unnecessary.

Recurrent urinary tract infection was seen in a 3-year-old girl with a ureterocele at the lower end of the upper segment ureter and reflux into the lower segment ureter of a duplicated kidney on the left side. We combined ipsilateral ureteroureterostomy (end-to-side anastomosis) with reimplantation of the host, single ureter into the bladder distal to the anastomosis to reduce dilatation, correct the reflux and keep the patient free of infection without medication.

The occult ureter in a duplex kidney should be recognized during the procedure time even if the intravesical orifice has not been visualized. In the opposite case it is possible to do some therapeutic errors. That is the reason why the authors report four new cases with five occult ureters in a duplex kidney. One is diagnosed during a second procedure for removing a stenosis on an unfortunate reimplantation with an acute renal failure. Four occult ureters were found during an intervention for a vesicorenal reflux on the functional ureter. The upper pouch was blind without any renal parenchyma in three cases and in two cases there was a little renal dysplasic parenchyma. In the four ureters where we have been able to observe the down pouch we have not seen an orifice in three cases and in one case the orifice was in ectopic position. Commentaries are done about the clinic context the similarities between this unrecognised ureter and ureterocele. Therapeutic approach is precised with the interest of an opacification during the procedure of all supplementary conduct discovered while the dissection of an ureter.

Ectopic ureterocele associated with double kidney and ureter was observed in 95 children and orthotopic ureterocele in 9 children. Most of them were the girls (91 of 104). All the children were operated upon (135 operations). The results were studied in 78 children within the terms from 1 to 10 years. Useful practical recommendations are given.

We report 2 cases of dilatation of the lower moiety ureter in a duplex kidney with ectopic ureterocele owing to intrinsic pathology at the ureterovesical junction. The relevant problems of this rare situation with double pathology are discussed.

A case is reported of uncrossed complete left ureteral duplication with the orthotopic ureteral orifice opening caudal to the ectopic orifice. Whereas the caudal orthotopic orifice was associated with a ureterocele and megaloureter, the cranial orifice was associated with a small undilated ureter. The orthotopic kidney was hydronephrotic, and the ectopic kidney was small and non-functioning. The ureterocele was excised together with the megaloureter and the small ectopic kidney also was removed. The undilated ectopic ureter was transplanted to the orthotopic kidney by performing a ureteroneocystostomy distally and ureteropelvic anastomosis proximally.

Eight children, 3 girls and 5 boys, with single ectopic ureters arising from non-concentrating kidneys are described. Two children, both girls, complained of persistent wetting with a pattern suggestive of ectopic ureter: 2 of the boys presented in the neonatal period with massive abdominal distension: the remaining children developed a urinary infection or chronic urinary retention. Diagnosis depends on an appreciation of the possibility that a non-concentrating kidney on intravenous urography may be giving rise to an ectopic ureter and, in the boys, on a correct interpretation of cystourethrographic findings. Careful endoscopic examination of the urethra and in the girls of the vagina also will lead to the identification of the ectopic ureteric orifice in most cases. When the ectopic ureter joins the male genital tract there may be an extravesical ureterocele which can be recognised cytoscopically. The condition is treated by nephroureterectomy.

A case of an ectopic ureterocele with a cystic dysplastic upper pole and atretic proximal ureter was studied. A four-month follow-up showed marked decrease in the size of the dysplastic upper pole which is explained on an embryologic and pathophysiologic basis.

From 1970 to 1977, 35 patients with ectopic ureterocele underwent a simplified treatment which consisted of the removal of the upper part of the kidney and its dilated ureter, but with no attention to the intravesical swelling. The procedure is straightforward and can be performed on very young children in poor physical condition. It can be used in all cases of ectopic ureterocele whether the contralateral upper urinary tract is normally refluxing or dilated. Of 33 cases with a reasonably long follow-up the results were good in 26 cases. In 19 cases the infection disappeared immediately and the ureterocele collapsed. If the lower ureter was dilated there was an improvement of its diameter in 13 of 14 cases. If the ureter was refluxing, the reflux disappeared in most patients. In only 7 patients did the reflux persist, necessitating a reoperation to reimplant the ureter and remove the ureterocele. In seven cases the results were not satisfactory: one case of dilatation in the superior contralateral urinary tract, two cases of persistence of reflux in the lower ureter and 4 cases in which the urinary infection persisted.

The wall of a ureterocele and the proximal ureter involved were investigated with light and electron microscopy. Emphasis in our study was on the muscular structure. In most cases, that is in patients with single or duplex, or simple or ectopic ureteroceles, muscle bundles were hardly developed in the dome of the ureterocele but were well developed in the proximal ureter, with and without dilatation. In the dome of the ureterocele muscle cells were much smaller than those in the proximal ureter. Thick and thin myofilaments were demonstrated in muscle cells in the proximal ureter but thick myofilaments were absent in the dome of the ureterocele. These findings may suggest that a ureterocele is a segmental embryonal arrest of the most distal portion of the ureter.
