[Nephrectomy without hemostasis of the pedicle].

The authors report a case of lithiasis of the renal pelvis which had progressed for several years and was complicated by severe perinephritis and peripyelitis. This inflammatory reaction around the kidney affected the renal pedicle and caused constriction of the renal artery. This arterial obstruction resulted in hypertension and such a reduction in the blood supply to the kidney that nephrectomy was performed without any haemostasis of the pedicle. This case is reported because of its rarity.
