The purpose of a CT urogram in a patient with urinary incontinence and recurrent UTIs is to:

• A. Define structural abnormality of the upper GU tract
• B. Distinguish the thickness of the bladder wall
• C. Visualize the quality of detrusor contractions
• D. Determine the post void residual

Answer: (A)

CT urogram is best for mapping the anatomy of the upper urinary tract and revealing structural abnormalities such as stones, strictures, hydronephrosis, tumors, or congenital anomalies. Incontinence with recurrent UTIs can be driven by anatomic issues that predispose to infection or obstructive problems, so this imaging helps identify those treatable causes involving the kidneys, ureters, or collecting system. The other options reflect functional tests or assessments not provided by CT urogram: evaluating detrusor contractions requires urodynamics, assessing bladder wall thickness is typically done by ultrasound or cystoscopy, and measuring post-void residual is done with a bladder scan or ultrasound.
