Urodynamic testing is the gold standard diagnostic tool for evaluating urinary incontinence. It objectively measures bladder pressure, urine flow rate, and sphincter function, helping to distinguish between different types of incontinence such as stress, urge, or mixed. This information is crucial for tailoring effective surgical or medical management. Other tests like Pap smear, MRI pelvis, or blood glucose estimation do not provide functional data on bladder dynamics. Hence, urodynamic testing guides precise treatment decisions, including surgical planning in refractory cases.
