The Effect of Shock Wave Lithotripsy on Urease-Positive Calculogenic Bacteria
Extracorporeal shock wave lithotripsy (ESWL) has been extremely effective among patients with infection-associated renal calculi. Given recent data regarding the adverse effect on shock waves on malignant cells, the possibility was raised that perhaps shock waves might also have an adverse effect on calculogenic bacteria. Accordingly, we studied the direct and indirect effects of shock waves on urease-positive bacteria. In all instances, utilizing a variety of bacteria, shock waves had no effect on bacterial viability. These results more strongly underscore earlier recommendations that patients undergoing ESWL should have a sterile urine. In those instances in which infection stones are suspected, appropriate parenteral antibiotic therapy should be instituted in order to sterilize the urine, and such treatment should be continued in the immediate post-ESWL period.
