[Complications in the postoperative period resulting in recurrent nephrolithiasis]

Under study were the factors influencing the recidivation of nephrolithiasis. An analysis of 1310 operations was made. Organ-preserving operations made up 90,3%. The analysis of repeated operations shows the transparenchymatous pathology for the removal of a kidney stone to be complicated by recurrent stones in 73% of cases. A disturbed outflow of urine not corrected in due time after operation results in purulent injuries of the kidney with or without a recurrent stone in 35,8% of cases. A recidivation of the disease is also related with urine leakage into the retroperitoneal fat. Technical improvement of the operative procedures and prevention of complications can make the operative treatment of nephrolithiasis more effective.
