dc.description.abstractPatients treated by extracorporeal shock wave lithotripsy (ESWL) 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 technetium-99m-diethylenetriaminepentaacetic acid and iodine-131-hippurate radionuclide renal imaging studies, and a plain abdominal radiograph as the initial followup study after ESWL of 64 kidneys in 55 patients. Of 53 kidneys studied within 60 days after ESWL 42 had abnormal radionuclide renal imaging studies demonstrating pelviocaliceal stasis, excretory delay or poor function, 8 of which required subsequent interventions for obstructing stone debris. Five patients had excretory delay after ESWL that was unexpected based on a pre-ESWL excretory urogram showing normal function without dilatation. A subset of 23 patients with large stone burden or anatomical deformity from a prior operation had baseline radionuclide renal imaging studies before ESWL; function improved in 4 and worsened in 5 by radionuclide renal imaging studies after completion of treatment. A total of 19 patients had radionuclide renal imaging studies earlier (within 17 days) after ESWL because of poor function and/or large stone burden, and as expected they had evidence of obstruction from stone debris, which necessitated further followup. Our experience suggests that followup of ESWL by radionuclide renal imaging studies provides specific functional information that is of particular value in the management of patients with obstructing stone debris and/or diminished renal function. Radionuclide renal imaging studies may also reveal unsuspected obstruction or functional impairment after ESWL of uncomplicated stones, and is recommended as routine followup after ESWL.
