[The prevention of infectious-inflammatory complications in the postoperative period in percutaneous surgical interventions in patients with urolithiasis].

The paper describes a number of modifications in the operative procedures, pre-, intra- and postoperative antibacterial treatment introduced to decrease the number and severity of infectious-inflammatory complications of endourological surgery for urolithiasis; presents the results of anti-bacterial prophylaxis of urinary infection aggravation in 29 patients suffering from urolithiasis combined with renal anomalies. Antibacterial treatment was performed with ftorquinolone drug ciprinol (ciprofloxacin hydrochloride) made in Slovenia. 18 patients received ciprinol twice a day at a dose 500 mg 3-5 days before the operation and within 5-7 postoperative days. The other 11 patients received the drug intravenously (100 mg in drops) in parallel with initial anesthesia and during 1-2 postoperative days. It was continued orally within the next 5-6 postoperative days. The analysis of ciprinol pharmacokinetic profile showed its concentrations in the blood and urine to surpass minimal inhibitory concentration for the majority of the isolated microorganisms. Out of 18 patients treated with oral ciprinol, postoperative aggravation of pyelonephritis occurred in 3 (16.7%) versus 8 (40%) cases out of 20 controls. 11 patients on intravenous ciprinol developed no complications. The conclusion is made on high efficacy of preoperative antibacterial preparation and of intraoperative antibacterial therapy continued for some time after the surgery in cases of percutaneous endoscopic surgical interventions for urolithiasis attended by chronic urinary infection. The antibacterial treatment brings about a 2-3-fold decrease in the occurrence of postoperative inflammatory complications.
