Conservative treatment of asymptomatic ectopic ureterocele: A report of two cases

INTRODUCTION: There are no established treatments for asymptomatic ectopic ureteroceles, with completely duplicated ureters, during the neonatal period and infancy. However, conservative treatment is sometimes successful. CASE PRESENTATION: Two patients were prenatally diagnosed, via ultrasonography, with left hydronephrosis. In each case, magnetic resonance imaging confirmed an ectopic ureterocele accompanying the left, completely duplicated ureter. Prophylactic antibiotics were administered and conservative treatment was started. Currently, one patient is 44 months old and the other is 49 months old; in neither patient has the ureterocele or hydronephrosis been exacerbated. CONCLUSION: Patients with (i) a nonfunctional kidney, (ii) mild hydronephrosis or moderate vesicoureteral reflux, (iii) no bladder neck obstruction on urination, and (iv) a Churchill classification ≤Grade II (Churchill classification) may be able to select conservative treatment.
