[Anastomosis of the total calyx system in solitary kidney with an ileal loop].

In a female patient with a solitary kidney the authors achieved a maximum drainage by means of an ileoneocystostomy comprehending the whole calyx system with lateral drainage between kidney and urinary bladder. The indication for this intervention was made in a much extended calyx system with stone formation, in which case the ureter and the urethra remained intact. The result of the operation and the function of the drainage were satisfactory after 2 years.
