Intravesical ureterocele in children.
Eighteen intravesical ureteroceles associated with single collecting system were found in 16 children over past 6 years. Hydronephrosis of varying severity, with hydroureter, was present in 10 patients. The ipsilateral kidney was nonfunctioning in 5 patients and normal in 1. The ureterocele was easily detected by ultrasound and usually revealed as a cystic mass in the bladder. On intravenous urogram the ureterocele usually showed a positive cobra-head dilatation. However, it may exhibit a negative filling defect when the function of the associated kidney is impaired. In this series, 9 patients were asymptomatic, and the condition was detected incidentally by ultrasound. 7 patients received surgery. The remaining 9 patients were followed up at an Outpatient Clinic.
