A simple operation for the management of simple, i.e. intravesical, ureteroceles, which we have named 'ostioplasty', is presented. After unroofing the ureterocele, the retracted, gaping ureteric ostium is advanced and fixed medially to the center of the bladder trigone with three 5-0 polyglycolic acid sutures. The exposed intravesical ureter is covered with a new mucosal layer formed from the mobilized lateral edges of the unroofed ureterocele, sutured together over the ureter with 5-0 polyglycolic acid. Ostioplasty has been used in 5 patients so far with excellent anatomic and functional results. It is a simple and valuable surgical option to standard ureterovesical reimplantation after excision of a simple ureterocele, provided that the ureterocele is of moderate size and the bladder trigone retains good muscular support.

The authors report three cases of a ureterocele and duplication of the ureter and the surgical technique using a flap of the surface of the ureterocele itself. This facilitates surgical repair of this anomaly and prevents dissection of the terminal section of the two ureters.

Ureteral triplicity is a rare abnormality of which there are less than a hundred cases reported up to date. The possible absence of clinical signs can explain why this malformation passes unnoticed specially when there are blind branches and dysplastic renal segments. The paper presents the case of a 43 year-old male, attending the clinic on a testicle tumour consultation, in which in spite of the previously mentioned circumstances a preoperative diagnosis of trifid ureter with ipsilateral ureterocele and renal dysplasia was reached owing to the use of C.A.T.

To determine the impact of prenatal detection on neonates with hydronephrosis of the upper pole of a duplex collecting system, we reviewed 40 such cases seen between June 1982 and April 1989. This six-per-year rate contrasts with fewer than one case per year that was seen at our hospital from 1947 to 1977. Nineteen patients had an ectopic ureterocele, and 21 had an ectopic ureter without a ureterocele. Thirty-three (83%) were girls. Thirty-three cases were discovered because of abnormal findings on a prenatal sonogram, and 20 of those infants were asymptomatic. In the 33 patients whose prenatal sonographic findings were abnormal, the sonogram was diagnostically precise for hydronephrosis of the upper pole of a duplex collecting system in only 39%. This imprecision did not adversely affect management or outcome. Postnatal sonography modified the prenatal diagnosis in 75% of these 33 patients. Voiding cystourethrography was the most sensitive and precise imaging technique for detecting both ureterocele and reflux. Lower pole reflux was almost twice as common when an ectopic ureterocele was present (63%) than when one was not (33%). Prenatal sonographic detection of hydronephrosis of the upper pole of a duplex collecting system decreased the proportion of neonates presenting with urinary tract infection and urosepsis because of prophylactic antibiotics initiated at birth and continued until surgical correction. Precise prenatal diagnosis was not needed for effective surgical treatment.

Five children (three girls and two boys) who had a duplex collecting system with an ectopic ureter or a ureterocele that was not detected with either imaging or cystoscopy were seen during a 10-year period. Four had urinary tract infection. The fifth was noted to have hydronephrosis when CT scanning of the abdomen was done for trauma. In each case, voiding cystourethrography showed reflux into what was thought to be a single (nonduplex) collecting system, but was found during surgery to be the lower pole of a duplex system. Excretory urography in four patients, sonography in two, and CT scanning in one did not show signs of duplication on the affected side. In each case cystoscopy failed to show a duplex system on the affected side. The diagnosis of duplication of the collecting system with ectopic ureter or ureterocele was made in each case only when the bladder was opened to reimplant the ureter. Direct opacification of the previously unsuspected upper pole ureter in each case showed it to be bind-ending and terminating at the level of the kidney. Radiologists and surgeons should be aware that duplex systems may not always be visible on urography and sonography.

A seven-month-old female child presenting with a large abdominal mass was found on investigation to have a duplex right kidney with a non-functioning obstructed upper moiety and a right ureterocele. The grossly dilated and tortuous upper moiety ureter presented as a large cystic mass on ultrasound and computed tomographic scans.

The method of diagnosis and therapeutic rules for pathological ureteral duplicity has been highly developed over the last few years. Recent advances in fetal ultrasonography sometimes allow an early diagnosis of renal or intravesical cystic structure to be appraised before complications (urinary tract infection or pyelonephritis, prolapsed ureterocele, recurrent orchitis, primary diurnal and nocturnal urinary incontinence with conserved micturation for a young girl). However, the basis of therapeutic rules remain unchanged, the superior pyelocaliceal system is not preserved in most cases of ureterocele with ureteral duplicity or ectopic ureter, because of major cystic dysplasia; although, in some cases when an earlier diagnosis is made, conservative treatment (primary endoscopy followed by a surgical intervention if necessary) can be proposed. Likewise, the endoscopic injection of Teflon causes the vesico-ureteral reflux to disappear in most cases (70%).

On the basis of 5 cases, the author show the possibilities of treating certain ureteroceles via an endoscopic approach only with incision of the ureterocele and elimination of the reflux thus created by an injection of teflon paste under the gaping ureterocele. The best indication for this method is an orthotopic ureterocele affecting a non-double ureter, i.e. the ureterocele usually seen in the adult. Orthotopic ureterocele in the presence of double ureter/kidney also seems suitable for treatment in this way. In contrast, ectopic ureteroceles are probably the least suitable indication.

A 4-year-old girl with the history of repeated urinary tract infections was referred from the pediatric department to our department on January, 1987. Under the diagnosis of right ectopic ureterocele of everting type with complete duplication of renal unit, the one-stage operation, that is, right hemi-nephroureterectomy with complete excision of the ureterocele and ureteral stump was carried out on January 27, 1987. Reimplantation of the orthotopic mate ureter was done because of injury to lower part of the mate ureter during operation, although reflux of the mate ureter did not exist. After the operation, the voiding symptom became better except for large residual urine volume (300 ml). In order to protect renal function, intermittent catheterization was carried out. Two years and 8 months after that operation, residual urine volume was reduced to 20 ml. Judging from the literature and our experience, if the patient is not in a severe condition, we recommend one-stage operation, that is, total correction (a single operation designed to correct abnormalities of the upper and lower urinary tract) for ectopic ureterocele in children.

Dilatation in the upper limb of a duplex ureter is usually secondary to obstruction and may be associated with a ureterocele. By contrast, vesicoureteric reflux is the usual cause of a dilated lower moiety ureter. We report 3 cases in which unusual or complex causes of dilatation of 1 limb of a duplex ureter were demonstrated.
