A supernumerary kidney is a rare congenital anomaly of the urinary tract. Association of supernumerary kidney with horseshoe kidney is even rarer and true incidence of this anomaly is not known because of its infrequent occurrence.

Neither computed tomography (CT) nor intravenous pyelography (IVP) alone can diagnose tumors of renal pelvic diverticula, but magnetic resonance urography (MRU) can obtain accurate preoperative information.

This review article comprehensively discusses multidetector CT urography protocols and their role in imaging of the urinary tract in patients with hematuria.

OBJECTIVE The purpose of this study was to determine the positive predictive value of CT urography in the diagnosis of upper tract urothelial malignancies. MATERIALS AND METHODS Retrospective review of the records of patients who underwent 2,602 CT urographic examinations revealed that 81 (3%) examinations of 77 patients had findings suggesting upper tract urothelial cancer. Two radiologists ...

(1) in a previous issue of Nephro-Urology Monthly (October 2011), regarding the comparison between intravenous urography and computed tomography urography in diagnosing ureteropelvic junction obstruction. As previously described, pathological lesions at the ureteropelvic junction are classified into intrinsic and extrinsic abnormalities. In the ca...
