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.

Transitional cell carcinoma of the bladder in children is rare, low grade, noninvasive and rarely recurrent. A l2-year old boy with painless gross hematuria showed a 1.5cm sized papillary mass on cystoscopy. Histologic examination showed grade I transitional cell carcinoma without muscle invasion. Three months postoperative cystoscopy and urine cytology were negative but adjacent vesical biopsy revealed carcinoma in situ. We report a case of transitional cell carcinoma of the bladder in a child and treated with transurethral resection and intravesical BCG therapy.
