[Kidney operations in ischemia (author's transl)]

Forty-two operations were done on patients suffering from extensive nephrolithiasis. The procedure was performed in the complete absence of blood, using a special clamp. No hypothermia was applied. The special clamp was placed at the renal hilum. The meantime of ischemia amounted to 17.8 min. The technique of this operative procedure is described. Complications, postoperative urograms, late follow-ups, and the results of differential isotope clearances are discussed.
