Abstract

Patients treated by extracorporeal shock wave lithotripsy are usually evaluated by excretory urography within 1 month after treatment to determine the clearance of stone debris and rule out asymptomatic obstruction. In an attempt to obtain more precise functional information, we used 99m-Tc-DTPA renal scan as the initial follow-up study after ESWL in 10 patients. GFR checked by renal scan shows no difference in pre and post ESWL. Our experience suggests that follow up after ESWL by radionuclide renal imaging studies provides specific functional information and also particular value in the management of patients with obstructing stone debris and diminished renal function. Radionuclide renal imaging studies may also reveal unexpected obstruction and functional impairment after ESWL of stones, and is recommended as routine follow-up study after ESWL.
