[Ectopic ureterocele].

An analysis of 43 clinical observations helped to establish three variants of ectopic ureterocele: ectopic ureterocele of the accessory ureter, ectopic ureterocele of the doubled ureter. Ectopic ureterocele always brings about obstruction of the ureter. Ectopic ureterocele of the accessory ureter was treated by making anastomosis between the accessory ureter and the main ureter with a removal of all the accessory ureter and dissection of ureterocele. The operation of heminephrureterectomy or dissection of ureterocele with resection of the paracystic part of the ureter were performed with antireflux utererocystoanastomosis.
