We evaluated 16 patients, 2 weeks to 8 years of age (median: 18 months), operated on for ectopic ureterocele. Five patients, in whom the upper kidney, drained by the ureter with the ureterocele, was viable, were submitted to excision of the ureterocele with reimplantation of the double ureter (n = 4) or high ureteroureterostomy (n = 1). A 2-week-old baby with a non-functioning kidney was treated by nephroureterectomy. The remaining 10 children with a non-functioning upper part of a duplex kidney were submitted to heminephrectomy with subtotal ureterectomy. In this group of patients no problems arose from the retained ureteral stump or the decompressed ureterocele, and vesicoureteral reflux accompanying the ureterocele resolved postoperatively in 6 of 10 ureters.

Double ureters are not a rare anomaly. In the great majority of duplex-ureter systems, both components are functionally normal. Some may present medical problems such as abdominal cystic masses and recurrent urinary tract infections, even from the newborn period. The choice of the best method of the operation depends on residual renal function, the form of ureters, the shape and the position of the ureter orifice, and other factors. So, there are many methods by which to operate on duplex-ureter systems. Total heminephroureterectomy may be the best method of choice, if the duplex-ureter portion is non-functional. It is however, very difficult to resect the pathological ureter with the mate ureter uninjured, when the mate is covered by a common sheath or the patient is very small. Recently, two patients were admitted to our hospital because of abnormal findings of intrauterine echogram. One of them had a large ureterocele with a dilated ureter whose upper pole duplex kidney was non-functioning and cystic. The other patient had an upper ureter orifice opening ectopically to vagina, a ureter dilated, and a non-functioning upper ple duplex kidney. For heminephroureterectomy, resection of the upper one-fourth of the upper pole ureter was easy. But further excision of ureter seemed threatening to the mate ureter. We applied the mucolysis method, which we had been using as the operation of Sowve's method for the patients with Hirschsprung diseases. The method was technically easy and safe. There have been no complications after 1 year of follow up.

Severe hydronephrosis and hydroureter associated with ectopic ureters were diagnosed in 2 dogs. Surgical transplantation of the ectopic ureters into the urinary bladder resulted in urinary continence in both dogs. Intravenous urography revealed a marked decrease in the size of hydronephrosis and hydroureter in both dogs 28 to 35 weeks after surgery. In 1 dog with bilateral ureteral ectopia, kidney size and renal function remained normal for 5 years after surgery. A dog with one ectopic ureter and an associated ureterocele had a marked reduction in size of the affected kidney and an apparent decrease in function of that kidney, as indicated by decreased opacification on an intravenous urogram.

Analysis of the clinical manifestations of the obstruction of the pelviureteral segment, of the vesicoureteral reflux, reflux and obstructive megaureter, ureterocele and ectopia of the ostium ureteris in 423 children has demonstrated that the clinical symptomatology of the abnormalities depends to a great measure on the degree of urodynamic disorders. The developmental abnormalities that provoke the obstruction of the initial part of the ureter manifest themselves primarily by the painful syndrome. Provided the urodynamics is disturbed in the inferior parts of the ureter, urination disorders become first and foremost.

By referring to two cases, the author demonstrates the possibility of managing certain ureteroceles exclusively by endoscopic treatment. On one hand, by incising or resecting the ureterocele and, on the other hand, by suppressing the reflux thus created with a Teflon injection under the gaping ureterocele. The best indication for this method is the orthotopic ureterocele on a nondivided ureter, i.e. the ureterocele normally found in adults. It also seems possible to treat the orthotopic ureterocele on a duplex kidney in this way. On the contrary, the worst indications for this method are probably ectopic ureteroceles.

The routine use of maternal ultrasonography has led to frequent discovery of fetal anatomical abnormalities of the urinary tract. Herein we report on 35 cases with congenital urogenital anomalies which were found during the last 5 years by the prenatal ultrasonography and referred to our clinic either for treatment or consultation. 1. Findings of prenatal ultrasonography There were 12 cases of hydronephrosis, 7 of multicystic dysplastic kidney, 4 of megaureter, 3 of posterior urethral valve, 2 of ureterocele, 2 of vesicoureteral reflux and 5 other cases. Fetal anomalies were diagnosed during routine maternal examination, as intrauterine growth retardation, oligohydramnios, or the recurrent risk secondary to genetic risk factor or previous abnormal pregnancies. Prenatal diagnosis was made as early as 20 weeks of gestation in a case of hypoplastic urethra with large bladder diverticula. In about 30% of cases, abnormalities were found before 30 weeks of gestation. Oligohydramnios was evident in 5 cases. Prenatal diagnosis was correct in about 60% of cases. In the remainder the diagnosis was either incomplete or incorrect. Errors in the diagnosis resulted from difficulties in the differentiation of dilated ureter, intestinal dilation or intraperitoneal cystic masses. 2. Management in newborn periods Of the patients, 12 were treated urologically in newborn periods. Although patients with distended bladder and dilatation of upper tracts first underwent therapeutic placement of the urethral catheter, upper tract diversion with nephrostomy or tubeless ureterocutaneostomy was required in 2 because of continued elevation of serum creatinine levels. In 2 neonates nephrectomy was indicated for unilateral multicystic kidney, because the large cystic mass might compress the intestine.(ABSTRACT TRUNCATED AT 250 WORDS)

Among 25 cases of double ureter which required surgical treatment, six were accompanied by ureterocele. Interpelvic anastomosis was performed in two cases with uretero-ureteral reflux. En bloc reimplantation was performed for ten double ureters, three of which had common ureteral orifice with reflux in both ureters. In three other cases there was a common segment with low bifurcation and ureteroureteral reflux which had to be excised in order to create two ureteral orifices in the bladder. Heminephrectomy with excision of the ureterocele combined with a simultaneous reimplantation of the ipsilateral ureter was performed in three cases. These cases were accompanied by a large ureterocele and reflux in the ipsilateral ureter. Upper-pole nephrectomy and partial ureterectomy without excision of the stump and ureterocele was performed in one case of small ureterocele without reflux. Excision of the ureterocele combined with en block reimplantation was performed in one case with relatively well preserved renal tissues. Follow-up results were satisfactory in the majority of the cases.

The paper reports on the results of the endoscopic treatment in 16 cases of orthotopic ureterocele, out of which 11 developed on a simplex ureter and 5 on the superior ureter of the pyeloureteral duplicity (ren duplex). In 6 patients the pseudocystic dilatation of the submucous ureter contained calculi. The endoscopic treatment consisted of: the ureterocele resection in 12 patients (in 6 of them it was associated with the extraction of the calculi with Lowsley's lithotryptic clip): the ureterocele incision in 3 cases; and the endoscopic resection of the intravesical sac, with nephrouretectomy of the dysfunctional pelvis and the respective ureter in one case. The results recorded showed urographic improvement in 14 patients and uroculture sterilization in 11 cases of 14 with postsurgical urinary infections. Only in one case, the ureterohydronephrosis advanced, requiring the subsequent ureter-bladder reimplantation. No case of bladder-ureter reflux following the endoscopic resection or incision of the orthotopic ureterocele was recorded. Endoscopic resection or incision is a simple and efficient method for treating small or middle orthotopic ureteroceles, if the superior urinary system is recoverable. The method is simple and with low risks, and it can be applied as first therapeutic time in all the cases, even in those in which the chance of the definitive solution is less probable, as in the secondary surgical time the classical surgical correction of the uretero-bladder junction can be used.

A case of cecoureterocele in a 22-month-old girl is reported. She was admitted because of recurrent urinary tract infection associated with fever and dysuria. Excretory urogram showed a left duplex kidney with hydroureteronephrosis of the upper and lower moieties. Although the left upper moiety was hypofunctioned, some excretion of contrast medium was noted. Voiding cystourethrography demonstrated reflux into the left upper moiety, and a prominent dilation of the bladder neck and the urethra. Bladder sonography demonstrated an ectopic ureterocele at the bladder neck, and it was diagnosed as a cecoureterocele by endoscopic examination. Left pyelopyelostomy, total ureterectomy from the left upper half kidney and open resection of the ureterocele were performed together with reimplantation of the left lower ureter using Cohen technique in 1 stage. At the operation, the left lower ureter was confirmed as a typical obstructive megaureter. Convalescence was uneventful, and postoperative excretory urogram revealed an improvement of the left pyeloureterogram. But the postoperative voiding cystourethrography showed a remnant of cecoureterocele in the urethra causing bladder outlet obstruction. Endoscopic incision of the remnant cele wall in the urethra resulted in marked improvement in voiding and complete resolution of urinary tract infection. A brief review of cecoureterocele was given.

Eight infants and children (six girls) were seen over a 13-year period with duplex collecting systems and ectopic ureteroceles. In each, there was striking dissimilarity in size between the large ureterocele and its diminutive ureter and calyces. The upper moiety did not function and, except for the ureterocele, the indirect urographic and direct sonographic signs of duplication were absent or subtle. We call this entity ureterocele disproportion. Seven patients presented with urinary infection and one was found to have hydronephrosis of a dilated lower moiety in utero. Five had ipsilateral lower-pole reflux, which ranged in degree from 3 to 5 (on a scale of 1-5). Two had bilateral duplication; one of these had a typical contralateral ectopic ureterocele. The diagnosis of ureterocele disproportion was strongly suggested by urography and sonography and was confirmed at cystoscopy by direct puncture of the ureterocele and opacification of the upper moiety. All had surgery. The approach varied and depended on the status of the lower moiety and the contralateral kidney. One had incision of the ureterocele only. Five with lower-pole reflux had excision of the ureterocele and ipsilateral common-sheath reimplantation.
