Results of operative treatment of Fraley's syndrome.

Relying on their own observations, the authors describe nine patients in whom Fraley's syndrome was diagnosed and treated operatively. In six of them, calycopyeloneostomy was performed. In three of the patients, because of complications, the upper pole of the kidney was excised together with the changed calyx. In noncomplicated cases the calycopyeloneostomy with a transposition of the artery beyond the cervix of the upper calyx allows to retain the active parenchyma of the upper pole of the kidneys.
