Heminephrectomy--ureterectomy as the sole procedure in ectopic ureterocele in children.

During the years 1976-1981, 12 children with duplex kidneys and ectopic ureterocele were operated upon with heminephrectomy and ureterectomy only. This simple procedure led to cure in 10 out of 12 patients. In two of the patients it later had to be supplemented by resection of the ureterocele and reimplantation of the orthotopic ureter. Such a two-stage procedure does not seem to jeopardize the final result.
