ABSTRACT
Objetivo: Exponer la experiencia del Servicio de Urología del Hospital Provincial Pediátrico, el tratamiento de las anomalías asociadas a la duplicidad ureteral. Métodos: Se hizo una revisión retrospectiva de 378 pacientes con duplicación ureteral, entre 1970 al 2010; se realizó tratamiento quirúrgico conservador a 26 casos y 6 casos de ellos tenían edad pediátrica, los cuales son objeto de análisis en este trabajo, según datos obtenidos en el registro de documentación médica de los centros. De los seis casos operados, a cinco se les realizó cirugía conservadora (uréteropielóstomia), y en un caso se realizó nefrectomía polar superior. Resultados: La duplicidad ureteral es una patología frecuente, determina un estasis urinario. El uréter bífido extra vesical, provoca reflujo urétero-ureteral. Conclusiones: Esta técnica quirúrgica es útil en las en las anomalías asociadas a la duplicidad ureteral. No se debe utilizar ésta cuando no haya posibilidades de conservación de parénquima renal.
Objective: To expose the experience of the Urology Service of the Teaching Pediatric Provincial Hospital, in the treatment of the anomalies associated with the ureteral duplication. Methods: We retrospectively reviewed the medical records of 378 patients with Ureteral Duplication attended in our center in the period 1970-2010; the surgical treatment was applied in 26 cases, and 6 of them were pediatric cases; the last ones are analyzed in this work, taking into account data obtained from the Clinical Documentation Database of the centers involved. The conservative surgery (uretero-pyelostomy) was carried out in 5 patients of the 6 cases and in the other 1 case, an upper pole we made upper pole nephrectomy. Results: The ureteral duplication is a frequent pathology that determines a urinary stasis. The extra-vesical bifid ureter causes uretero-ureteral reflux. Conclusions: This surgical procedure is useful in the anomalies associated with the ureteral duplication. It should not be used when there are not possibilities of conserving the renal parenchyma.
ABSTRACT
PURPOSE: A complete duplicated collecting system complicated with an ectopic ureter or ureterocele results in renal damage due to a ureteral obstruction or reflux. The clinical outcome of ureteropyelostomy in complicated complete duplicated collecting system was evaluated. MATERIALS AND METHODS: 20 children received a ureteropyelostomy for either an ectopic ureter or ureterocele with a complete duplicated collecting system anomaly. The median age was 3.2 months. Of the children, 11 had ureteroceles including 7 cecoureteroceles, and 9 had ectopic ureters. The associated anomalies were 3 UPJ obstructions of the lower pole and 9 VUR. All received a ureteropyelostomy. The lower pole ureter was used as the common ureter except in 2 cases with a lower ureter in poor condition. A lower pole pyeloplasty was combined in 3 cases with UPJ obstructions of the lower pole. A distal ureteral stump was left open except in the cecoureterocele in order to prevent VUR. Their clinical courses were followed up with an ultrasonogram and 99mTc-DMSA scan. The median follow-up after surgery was 17.8 months. RESULTS: A reduced upper pole hydronephrosis was observed in 19 patients and an improvement in the differential renal function was noted in 17 patients on the follow-up studies. All ureteroceles had either disappeared or were reduced in size. 7 patients showed an intermittent asymptomatic bacteriuria and 1 patient showed symptomatic UTI who required an ureteroneocystostomy during the follow-up. CONCLUSIONS: A ureteropyelostomy is recommended as a first-line treatment modality for patients with a complicated complete duplicated collecting system owing to the lower chance of secondary surgery, the prevention of deterioration in the bladder function and the possibility of early correction.
