I. Bada Bosch et al.CIRUGÍA PEDIÁTRICA ResumenObjetivo. Evaluar la eficacia del tratamiento endourológico del ureterocele ectópico en niños en una serie amplia y con seguimiento a largo plazo.Material y métodos. Estudio retrospectivo descriptivo de los pacientes con ureterocele ectópico intervenidos en nuestro centro en los últimos 15 años. Todos los pacientes se tratan por vía endourológica, tanto el ureterocele como el reflujo vesicoureteral (RVU) postoperatorio.Resultados. Se trataron 40 pacientes, 55% eran izquierdos y 5% bilaterales. La edad media al diagnóstico fue de 4,97 meses siendo de diagnóstico prenatal el 54,1%. En todos los pacientes menos uno se realizó una punción endourológica del ureterocele. La edad media en el momento de la cirugía era de 6,96 meses (0-1,11). La cirugía fue ambulante en un 94,9% de los pacientes. No se registraron complicaciones perioperatorias. En los últimos 30 pacientes no se realizó cistouretrografía miccional preoperatoria. Un 72,5% de los pacientes presentaron RVU postoperatorio (44,8% a pielón superior, 10,3% a pielón inferior, 17,2% a ambos, 6,9% al sistema contralateral y 20,7% bilateral), pero este se resolvió con un único procedimiento endoscópico en un 48,1% de los casos (curación del 65% de los pacientes con dos procedimientos). El RVU no se resolvió de forma endoscópica en 3 pacientes que requirieron un reimplante ureteral. Seis pacientes precisaron heminefrectomía (n= 3) o nefrectomía (n= 3) por anulación funcional e infecciones.Conclusión. El tratamiento endourológico del ureterocele ectópico es una técnica poco agresiva invasiva que consigue la resolución de la obstrucción de forma ambulante permitiendo diferir la cirugía vesical (si fuera necesaria) fuera del periodo neonatal.
Objective. To assess the efficacy of the endourological treatment of ectopic ureterocele in children in a large series and with a long-term follow-up. Materials and methods.A retrospective, descriptive study of patients with ectopic ureterocele who had undergone surgery in our institution in the last 15 years was carried out. All patients were treated using an endourological approach, both for ureterocele and postoperative vesicoureteral reflux (VUR).Results. 40 patients were treated -55% with left involvement and 5% with bilateral involvement. Mean age at diagnosis was 4.97 months, with diagnosis being established prenatally in 54.1% of cases. In all patients but one, endourological puncture of the ureterocele was conducted. Mean age at surgery was 6.96 months (0-1.11). Surgery was performed on an outpatient basis in 94.9% of patients. No perioperative complications were recorded. In the last 30 patients, preoperative voiding cystourethrography was not carried out. 72.5% of patients had postoperative VUR (44.8% into the upper pyelon, 10.3% into the lower pyelon, 17.2% into both, 6.9% into the contralateral system, and 20.7% into the bilateral system), but it was resolved with a single endoscopic procedure in 48.1% of cases (65% of patients were healed with two procedures). VUR was not endoscopically resolved in 3 patients who required ureteral re-implantation. 6 patients required heminephrectomy (n=3) or nephrectomy (n=3) as a result of functional impairment and infections. Conclusion:The endourological treatment of ectopic ureterocele is a little aggressive and little invasive technique that allows the obstruction to be resolved on an outpatient basis, which means bladder surgery -if required-can be performed outside the neonatal period.
