[Complications following nephrectomy and nephrostomy in calculi]

A report is given on the rate of complication in connection with 139 operations with incision of the renal parenchyma (= 29.3% of all operations to remove calculi). The number of early complications (urinary fistulas, secondary healing, vestigial calculi) is the same after polar resection and pyelocalicotomy as after pyelotomy, but is significantly greater after nephrectomy. The importance of temporary drainage of urine after nephrotomy and especially after operations in the stage of anuria is pointed out. The rate of complication for the various operations lies between 18.7 and 50%.
