[Kidney functions after electropiezolithotripsy]

To study the effect of the "Piezolit-2300" impulses on renal parenchyma at electropiezolithotripsy (EPL), the authors employed dynamic nephroscintigraphy (10 patients) and indirect angiography (10 patients) with 131I-hippuran and 99mTc-Mag3. The measurements were made before EPL and during 24 hours after it. No serious changes in either the target or contralateral kidney were observed because of a high-pressure small zone in the generator focus. Minor traumatism of the method allows its outpatient application as well as repeat use in case of large concrements.
