The influence of lithotripsy methods on the incidence of auxilary procedures after ureteric stone desintegration]

Introduction/ Aim. Localization of ureteric stone.,, and the differcrice in disintegration success arc the most important but not the only factors in choosing the first treatment approach to ureteric stones. The aim of the study was to investigate the incidence of auxiliary procedures after different ureteric stories lithotripsy modalities. Methods. In a prospective bicentric study patients with ureteric stones were analyzed. The patients weve divided into two groups: group 1 - 120 patient-subjected to extracorporeal shock ware lithotripsy (ESWI) treatment and group 11 - 140 patients treated cricloscopicINT with ballistic lithotripsy using "Swiss" Lithoclast. Results. Hudoscopic treatment of all distal ureteric stories was significantly more Successful than ESWL, but not significantly more Successful than ESWL. regarding proximal ureteric stones except for stones larger than 100 mm(2) that were significantly better treated with endoscopic method. There was no general significant difference in auxiliary procedures rate after lithotripsy I)cmTccn the two groups. In the group I auxiliary procedures Nvcrc significantly more performed than in the group 11 after the lithotrips\7 of stones larger than 100 mm(2), calcium-oxalat-monohydrate stones and highly significantly more performed after the treatment of stories located in the iliac ureteric portion and impacted stones. After the lithotripsy of lumbar ureteric stones and multiple stones situated in different ureteric portions additional procedures were highly significantly more necessary in the goup II than in the group I. Conclusion. Being significantly more successful comparing to ESWL, ureteric stone treatment with "Swiss" Lithoclast Should be considered the first therapeutic option for all, especially, impacted stones located in iliac and pelvic ureter. In spite of a statistically significant difference in success rate, ESWL should be performed as the first treatment option in all cases of lumbar stones as well as multiple stones located in different ureteric portion because of lower auxiliary procedures rate except for stones larger than 100 mm(2) that should be primarily treated endoscopicly.
