[Extracorporeal shock-wave lithotripsy (ESWL) in removal of stones in anomalies of kidney and upper urinary tracts].

Abstract

The authors analyze the results of ESWL (URAT-P unit) for urolithiasis performed in 106 patients (49 females and 57 males) aged 16-67 years with anomalous kidneys and upper urinary tracts. 28, 1, 11, 14, 24, 4, 22 and 2 patients had horseshoe, L-shape, solitary, lumbar distopic, double, sponge, cystic kidneys, congenital megacallicosis, respectively. The stones ranged in size from 7 to 30 mm. Bilateral urolithiasis was in 7 patients. The number of impulses averaged 1745 +/- 168.4 per the procedure. The average number of ESWL procedures per stone was 1.4 (1-4). The stones were completely eliminated after one ESWL session in 78(73.6) patients, after two sessions in 23(21.7%) patients, after three sessions in 4, after for in 1 patient. Complications developed in 18 patients: urinary tract obstruction and attack of acute pyelonephritis (15 and 3 patients, respectively). Within 2-10-year follow-up recurrences arose in 12 patients who were retreated. Thus, ESWL is a method of choice in the treatment of urolithiasis patients with malformations of the kidneys and upper urinary tracts. Good results of ESWL are achieved in strict adherence to principles of the patients' selection, preoperative preparation technique, individual approach to patients in postoperative period, follow-up to detect complications and recurrences.
