The reasons of unsatisfactory results of extracorporeal shock wave lithotripsy in patients with ureterolithiasis

The article dedicate to the problem of failure extracorporeal shockwave lithotripsy in patients with ureterolithiasis and reveal changes which appear ureter location stone.The aim. Analysis results treatment patients, suffering ureteric stones, using ureterolithotripsy procedure after lithotripsy.
 Materials methods. In 137 whom was conducted, symptoms disease, diagnostic methods value, efficacy surgical reasons previous method were analyzed.
 Results. 135 endoscopic removal stones has been succeeded, 2 because total obliteration ureter, uretero-ureteral anastomosis performed. If symptoms, are characteristic ureterolithiasis, persists up one week don’t cause significant macroscopic wall. stone longer than a we identified local appearing oedema. Long–term (more two months) persistence increase risk intramucosal “ingrowth” calculi greatly.
 Conclusion. URS ESWL high effective minimal invasive intervention for guaranteeing level postoperative “stone free rate”. Prolongation insertion time causes wall changes, complicating performance interventions (ureterolithotripsy shock–wave lithotripsy) reduce its efficacy.
