Renal impairments after extracorporeal shock wave lithotripsy (ESWL) were evaluated ultrasonographically. Twenty-three patients with renal stones were examined by ultrasonography within thirty minutes both before and after ESWL.
In seven cases, perirenal or subcapsular fluid collections were identified. The differences in the transverse diameter and the parenchymal thickness of the treated kidney before and after ESWL were significant, so enlargement of the treated kidney was suspected. In six cases, enlarged and conspicuous renal pyramids were identified, similar to renal allograft rejection or acute tubular necrosis. Histograms of twenty cases indicated increased contrast between renal pyramids and cortexes.
We deduced that these changes reflected damage to renal vesseles and urinary tubules, which took place during ESWL.
In conclusion, ultrasonography is helpful when evaluating renal impairment after ESWL.
