[Conservative surgery--a basic principle of childhood urology]

Abstract

Dysfunction of the solitary kidney was established in 58 patients after the contralateral kidney removal in childhood. The tests were made at senior school age, at adolescence, at adult age. The disorders in the renal function were more severe in pathological processes in the solitary kidney: chronic pyelonephritis, nephron dysplasia, etc. In 49 children the kidney was preserved even in functional failure 70-90%. These patients had less evident renal failure. Basing on this evidence and other arguments, the authors recommend to limit indications for nephrectomy in children.
