[Ureteral calculi: comparison of echographic and radiologic scanning]

The ureteral calculi can be treated, today in situ with extracorporeal shock wave lithotripsy. In our study we have used three different lithotriptors, two with fluoroscopic scanning, one with ultrasound scanning. The patients we have treated with ultrasound scanning lithotriptor Dornier MPL 9000 were 48 (22M-26F), while 210 patients were treated with fluoroscopic scanning lithotriptor, respectively 23 (15M-8F) with Direx Tripter XI and 187 with Dornier HM3. The ureteral calculi were so localized: among the patients treated with ultrasound scanning lithotriptor 16 presented calculi in the upper third ureter between GPU and L3, 9 in the middle third ureter between L3 and the superior border of sacroiliac articulation, 9 in pelvic tract above the spinoischiatic line, 6 between this line and juxtabladder ureter and 8 in juxtabladder ureter. Among the patients treated with fluoroscopic scanning lithotriptors all together 58 presented calculi in the upper third ureter between GPU and L3, 29 in the middle third ureter between L3 and the superior border of sacroiliac articulation, 13 in the iliac tract of the ureter, 41 in pelvic tract above the spino-ischiatic line, 27 between this line and juxtabladder ureter and 42 in juxtabladder ureter. For every treatment the number of shock waves was 2500 and the number of treatments for every patients was 1, 3. We report 82% of patients stone-free at a follow up of three months for the patients treated with the MPL 9000, 87% of patients stone-free for Direx Tripter XI and 85% of patients stone-free for Dornier HM3.(ABSTRACT TRUNCATED AT 250 WORDS)
