Risk Of Diabetes Mellitus (IDDM) After Lithotripsy Or Ureteroscopy For Urinary Stone Disease


Researchers from the University of Tennessee in Memphis have found an increased number of ueteroscopy ( URS) treatments significantly predicts the onset of diabetes mellitus compared to SWL. The study included 713 consecutive patients treated with Shock-wave lithotripsy (SWL) and 146 consecutive patients treated with ueteroscopy (URS).

At the end of the study, it was found of the 713 SWL patients, 137 had pre-existing diabetes mellitus. Of the remaining patients 9.9% developed de novo diabetes mellitus during an average follow-up of 45 months. On the other hand, in case of 146 URS patients 24 had pre-existing diabetes mellitus. Of the remaining patients 7.3% developed de novo diabetes mellitus with an average follow-up of 39 months.

When comparing the de novo diabetes mellitus after SWL and URS, only the total number of treatments 1.7 SWL versus 2.0 URS treatments, (P<0.001) significantly predicated the onset of diabetes mellitus. Age, gender, ethnicity, and laterality of stone disease were not significant risk factors for de novo diabetes mellitus.

The study was presented at the Annual Meeting of the American Urological Association.
