Abstract
Objective: To determine mean skin to stone distance (SSD) for successful disintegration of renal stones in patients undergoing shock wave lithotripsy (SWL) for the treatment of renal stone. Methodology: This descriptive cross-sectional study was conducted at the department of Urology, Sindh Institute of Urology and Transplantation, Karachi. A total number of 91 patients having stone size > 4 mm was included in the study. Mean SSD was measured using NCCT before treatment with SWL. Data analysis was carried out using SPSS version 20.0. Results: Out of 91 patients, there were 59 (64.8%) male and 32 (35.2%) females. The mean age of patients was 45.75 ± 10.03 years. Mean duration of kidney stone disease was 8.28 ± 4.21 months. Mean size of kidney stone was 12.95 ± 3.24 mm. Mean SSD was 70.72 ± 6.01 mm. Complete stone disintegration occurred in 84 (92.3%) patients while it was unsuccessful in seven (7.7%) patients. Mean SSD in patients with complete stone disintegration was 69.52 ± 4.45 mm and was 94.71 ± 2.28 in patients with unsuccessful stone disintegration (p < 0.001). Conclusion: Mean SSD was 69.52 ± 4.45 mm in patients with successful stone clearance. SSD was higher in overweight to obese patients as compared to the normal weight patients. Keywords: Shock wave lithotripsy, non-contrast computed tomography, skin to stone distance, renal stone.
