[Complications of open surgical procedures in urolithiasis and their prevention].

236 operative interventions for urolithiasis have been performed in 234 patients. Of them, 187 (79.9%) patients developed complications. Intraoperatively complications resulted from opening of the pleural and abdominal cavities (20 patients, 8.5%) and intraoperative blood loss < 500 ml (19 patients, 8.1%). In one case a nephrectomy was made because of repeated hemorrhage early after the operation. Among the postoperative complications most frequent were acute pyelonephritis (34, 14.5%) and aggravation of renal failure (11, 4.7%). The former demanded extracorporeal detoxication in 9 cases, in the latter hemodialysis was not required. Residual comcrements occurred in 28 (12%) patients. 17 of them had to undergo extracorporeal lithotripsy. Thus, open urological interventions in urolithiasis are now conducted in advanced disease, provoking complications. This raises responsibility of the surgeons who must take maximal preventive measures and use novel technologies in management of the complications.
