Ureterocele*

Ureteropelvic junction obstruction and duplicated collecting system are common urologic anomalies in upper urinary system, but they seldom occur in combination. These obstruction can occur in both partial or complete duplicated collecting system. Complete duplication of the ureter may be asymptomatic or recognized when complications develop as a result of reflux into the lower pole ureter or obstruction of the upper pole with an ectopic ureterocele. It is difficult to choose an optimal therapy due to the high variability in function, degree of obsturction, damage and potential for regeneration in growing kidney. We report our experience of successful surgical interventions in the ureteropelvic junction obstruction of the lower pole with complete duplicated collecting system.

The authors report two infants with unilateral duplex ureteroceles treated successfully by simplified operation at the age of 3 months and 11 months. Both had been prenatally diagnosed by ultrasound at the 24th and 32nd week of gestation. By the way the authors suggest the importance of prenatal diagnosis and monitor the evolution in order to plan an early postnatal surgical correction

Between April 1992 and March 2001, a total of 52 patients (58 ureteroceles) was diagnosed and treated at National Pediatric Institute. For ureterocele, female to male ratio was 5.2:1. Complete duplication was found in association with the ureterocele in 50 cases. Urinary tract infection was the most frequent mode of presentation (64%), abdominal mass (12%) and prolapsed ureterocele (13%). The diagnostic procedure included ultrasonographic examination, voiding cystourethrography and excretory urogram. Of 52 patients, 82% and 77% were less than 2 years old at presentation and operation respectively. The elective surgical policy was individualized, based on renal function and presence of vesicoureteral reflux. Overall results within various groups were generally satisfactory regarding the eradication of urinary tract infection, the preservation of renal function in 73% cases after the first procedures

Ectopic ureteroceles have a broad spectrum of presentation, anatomy and pathophysiology and the management is controversial. Herein, we report our experience of the management in 7 children with 8 ectopic ureteroceles associated with complete duplicated systems. Two functioning upper renal segments were able to be salvaged with ureteropyeIostomy and common sheath ureteral reimplantation. Four small ureteroceles not associated with reflux managed successfully with upper tract correction only(3 heminephrectomy and 1 ureteropyelostomy). Three children with ectopic ureteroceles associated with reflux and/or outlet obstruction underwent successful one stage total reconstruction which included heminephrectomy, ureterectomy, ureterocelectomy and lower pole ureter reimplantation. In summary, the management of ectopic ureterocele must be individualized taking into considerations the salvageability of renal segments, presence of reflux and/or outlet obstruction.

Hydronephrosis is the most common urogenital anomaly with the potential for obstructive process. And ultrasonography, as a first-line imaging modality, is a useful tool for evaluation of prenatal and postnatal hydronephrosis, even though evaluation of renal function is still needed. In this article, we review the common causes of congenital hydronephrosis and the sonographic findings of those diseases.

Ureterocele is a cystic dilatation of the intravesical segment of the ureter. In the ectopic ureterocele the ureteral orifice opens at a point other than its normal upper pole position, usually at the bladder neck or in the urethra, and is commonly associated with the upper moiety of a duplicated collecting system. Reflux into the ipsilateral lower pole ureter occurs in almost 50 per cent of ectopic ureterocele. But reflux into the ureterocele is rare. Recently we experienced a case of ectopic ureterocele associated with reflux into the ureterocele and treated successfully by heminephrectomy and total ureterectomy.

We report a case of uncrossed complete ureteral duplication with the orifice of the upper system ureter opening in the cranial and lateral positionin the bladder. There was reflux only to the upper system of the duplex kidney and the orifice of the lower system ureter in caudal position was associated with a ureterocele, and the lower pole system was large and non-functioning. The patient was treated successfully by lower pole heminephrectomy and ureterectomy.
