Abstract
PURPOSE: To compare the effectiveness and safety of shockpulse with pneumatic lithotripsy in percutaneous nephrolithotomy. METHODS: A prospective randomized comparative study was performed in Department of Urology, Bir Hospital for 1-year duration with 61 patients in shockpulse (Group 1) and 58 patients in pneumatic lithoclast (Group 2) groups, respectively. Patient's demographics, stone characteristics, hemoglobin drop, hospital stay, operative duration, stone fragmentation time and postoperative complications were compared. RESULTS: The two groups did not differ significantly in terms of patient's demographic and stone characteristics. The mean hemoglobin drop was 1.96 ± 1.48 g/dl in Group 1 and 2.32 ± 1.38 g/dl in Group 2 (p = 0.16) and hospital stay was 3.14 ± 1.42 days in Group 1 and 3.29 ± 1.82 days in Group 2 (p = 0.62). The number of cases that required multiple tracts were six (9.8%) in Group 1 and 12 (20.68%) in Group 2 (p = 0.12). The stone-free rates were 78.69% in Group 1 and 74.13% in Group 2 (p = 0.66). Mean total operation time was 43.23 ± 18.49 min in Group 1 as compared to 51.53 ± 19.48 min in Group 2 (p = 0.0188). Mean stone fragmentation time was 17.95 ± 15.25 min in Group 1 and 24.37 ± 11.12 min in Group 2 (p = 0.0096). Overall complications were not significant between the two Groups (p = 0.58). On sub-analysis of the patients with single tracts in both groups the results were comparable to patients with single and multiple tracts combined. CONCLUSIONS: Despite similar stone-free rates and complications between the two Groups, shockpulse has significantly lower stone fragmentation time and total operation time as compared to pneumatic lithotripsy.
