Urodynamic studies are tests that help doctors understand how well the bladder and urethra are functioning. These tests measure the pressure and flow of urine, as well as how well the bladder stores and releases urine. They are often used to diagnose conditions like urinary incontinence or overactive bladder. During a urodynamic study, a small catheter is inserted into the bladder to fill it with fluid. Patients may be asked to cough or urinate while measurements are taken. The results can guide treatment options and help improve bladder health.
