Answer

Patients with urinary incontinence should undergo a basic evaluation that includes a history, physical examination, and urinalysis. In selected patients, the following may also be needed:

  • Voiding diary

  • Cotton swab test

  • Cough stress test

  • Measurement of postvoid residual (PVR) urine volume

  • Cystoscopy

  • Urodynamic studies (see the image below)

Note the presence of multiple uninhibited detrusor contractions (phasic contractions) that is generating 40- to 75-cm H2O pressure during the filling cystometrogram (CMG). He also has small bladder capacity (81 mL), which is indicative of poorly compliant bladder.
