Does extra corporeal shock wave lithotripsy predispose patients to diabetes mellitus? Prevalence of diabetes mellitus after ESWL in 15 years follow-up

Abstract

Background and Purpose To investigate the hypothesis that extra corporeal shock wave lithotripsy (ESWL) increases the risk of new onset diabetes mellitus (DM) or significant changes in FBS. Materials and Methods A total number of 307 patients enrolled in this study. All of them had undergone ESWL for kidney stone from 1991 to 1994. In 2009, after 15-19 years, we invited patients to check their Blood Sugar. Results there were 307 patients, 19.8% female, and 80.1% male. Mean age of the patient were 44 for female and 42 years for males.47.5% had kidney stone in left side, 42.9% in right side and 9.4% bilateral. The mean FBS increasing was 11.86 g/dl. It was 14.54 g/dl for right side, 8.57 g/dl for left and 16.24 g/dl for bilateral ESWL. Conclusions The increasing of FBS is more significant in shock wave intensities higher than 15.5 KV. And there wasn't any significant relationship between age, sex, BMI and total number of shock waves with increasing of FBS. ESWL treatment might associate with increasing FBS without relation to age, sex and BMI.
