An NP is assessing an adult patient who presents with urinary incontinence when coughing, laughing, or sneezing. They report no urge to urinate prior to the incontinence. Which of the following diagnostic tests should the NP utilize for the initial evaluation of these findings?

The patient's presentation — urine leakage triggered by increases in intra-abdominal pressure such as coughing, laughing, or sneezing, without a preceding urge to void — is classic for stress urinary incontinence. The bladder stress test is the appropriate initial diagnostic tool for evaluating stress urinary incontinence. This bedside test involves having the patient cough vigorously while the clinician observes for immediate urine leakage, which confirms the diagnosis. Postvoid residual measurement is used to evaluate for urinary retention and detrusor underactivity, conditions not suggested by this presentation. Urethral mobility evaluation, such as the Q-tip test, can provide supplementary information about urethral hypermobility in stress incontinence but is not the first-line diagnostic test. Urodynamic testing is a more invasive, comprehensive study reserved for cases where the diagnosis is unclear, conservative treatments have failed, or surgical intervention is being considered. Starting with the simplest, least invasive, and most clinically relevant test is consistent with best diagnostic practice. Confirming stress incontinence with the bladder stress test guides initial management, which may include pelvic floor exercises, lifestyle modifications, and referral for physical therapy or surgical evaluation if conservative measures fail.
