[Surgical management of double kidney in children].

In 48 patients a heminephrectomy was carried out on account of a chronic relapsing pyelonephritis when a double kidney was present which for the largest part was combined with vesico-ureteral reflux, pyelectasia and hypertension. The partly severe histologic changes found in more than 80% in the resection preparation confirmed the supposition that in the majority of the cases the chronic relapsing inflammation issues from the hypoplastic renal pole with a decreased function. Also the courses observed in more than 3/4 which had no recidivation after operation show the possibility of the causal-surgical therapy in chronic relapsing pyelonephritis with double kidney, when the indication is correct.
