ABSTRACT
We attempted to compare the result of EDAP LT-01+ lithotripsy with Modulith SLX lithotripsy for management of urinary stones. We evaluated 1,544 patients (1,731 renal units) treated with EDAP LT-01+ ESWL (Group A) and 668 patients (707 renal units) treated with Modulith SLX ESWL (Group B). The results were obtained as follows; 1. Between the group A and B, stones were located in kidney (except staghorn calculi) in 666 cases (38.5%) and 160 cases (22.6%), in staghorn calculi in 31 cases (1.8%) and 13 cases (1.8%), in ureteropelvic junction (UPJ) in 65 cases (3.8%) and 19 cases (2.7%), in upper ureter in 469 cases (27.0%) and 200 cases (28.3%), in lower ureter in 491 cases (28.4%) and 271 cases (38.3%) and in bladder in 9 cases (0.5%) and 10 cases (1.4%), respectively. 2. Success rates according to stone size were 99.4% and 99.6% in less than 1 cm:, 97.5% and 97.2% in 1 cm2 to 2 cm2, 92.4% and 91.3% in 2 cm2 to 3 cm2 and 82.2% and 78.1% more than 3 cm2 respectively in the group A and B. There. was no statistically significant difference between two groups (,p>0.05). 3. Success rates ccording to stone location were 98.8% and 100% in renal stone (except staghorn calculi) , 83.9% and 84.6% in staghorn calculi,92.3% and 94.7% in UPJ stone, 97.7% and 98.5% in upper ureteral stone, 98.4% and 98.6% in lower ureteral stone and 66.7% and 30% in bladder respectively in the group A and B. There was no statistically significant difference between two groups (p>0.05). 4. Average shock wave sessions and time (min.) were 4.0 and 1.8 and 42.1 and 28.6 respectively in the group A and B. These differences were statistically significant (p=3 days) in 1.6% and 10.7%, steinstrasse in 5.1% and 12.5%, fever (>=38 degree C) in 2.1% and 2.3% and perirenal hematoma in 0% and 0.7% respectively in the group A and B. We concluded that success rates according to location and size of urinary stone were similar between two groups. But, treatment time of the group B was significantly shorter than that of the group A. Treatment sessions of the group B were decreased compared with the group A. Gross hematuria and steinstrasse were occurred significantly more in the group B compared to the group A (p<0.05).
