[Do shock waves damage the kidney? Morphologic and functional changes of the kidney following exposure to shock waves].
The introduction of extracorporeal shockwave lithotripsy (ESWL) as a routine procedure has brought about a dramatic change in the therapy of urolithiasis. More than 500,000 patients have been treated successfully. Although a tissue damaging effect of the shock wave on the kidney was regarded as non-existent, phenomena such as hematuria during ESWL treatment and subsequent subcapsular hematomas suggest the possibility of damage in the region of the renal parenchyma by the shockwave itself. To investigate this possibility canine kidneys were examined histologically at different intervals after shockwave exposure. Extensive histological changes such as hemorrhage and sometimes direct tubular damage were found, with scar formation after three months. These changes are limited to the areas exposed to ESWL treatment.
