SHOULD RENAL ULTRASOUND BE PERFORMED IN THE PATIENT WITH MICROSCOPIC HEMATURIA AND A NORMAL EXCRETORY UROGRAM

Purpose: We determine what additional information would be detected by renal ultrasonography that was not identified by a normal excretory u rogram (IVP) performed for the evaluation of microscopic hematuria. Ma terials and Methods: A retrospective review was done of 101 patients w ith microscopic hematuria and a normal IVP who underwent renal ultraso nography. Results: Of the 101 patients with microscopic hematuria and a normal IVP, renal ultrasonography was abnormal in 20%. All findings were ultimately proved to be of no clinical significance, although 6 o f 21 patients required a total of 10 additional studies, including 9 c omputerized tomography scans and 1 renal arteriogram. Conclusions: The se data demonstrate that renal ultrasonography is unnecessary in a pat ient with microscopic hematuria and a normal IVP.
