In a patient who complains of urinary incontinence, cystometrogram is performed to: (LQ)



A Determine urethral length

B Rule out uretero vesical reflux

C Diagnose stress urinary incontinence

D Determine if a patient has normal bladder sensation

Ans. D
Determine if a patient has normal bladder sensation

1. As a catheter is introduced for performing a cystometrogram, measurement of residual urine is obtained. During the cystometrogram, a normal first sensation is of fullness felt at 100 mL. Urge is felt at approximately 350 mL, with maximum capacity at 450 mL.

2. The primary reason to perform a cystometrogram is to rule out uninhibited detrusor contractions.

3. The cystometrogram is a urodynamic test, and it cannot determine whether ureterovesical reflux exists. The degree of reflux can be evaluated with the voiding cystogram, a radio- logic test.
