The clinical manifestation of urinary incontinence is primarily the involuntary leakage of urine, where the patient lacks the ability to control urination. Diagnosis mainly involves reviewing the patient's medical history and a physical examination, which in most cases is sufficient to understand the type and cause of the incontinence. A urodynamic test is crucial for a definitive diagnosis. The contents of the urodynamic examination include the assessment of bladder and urethral function. If a patient exhibits the aforementioned symptoms, they should visit the urology department of a hospital for formal evaluation and treatment.
