Definition
Videourodynamics are a group of tests used to study the bladder and the flow of urine. These tests show how well the bladder and the connecting tubes (the urethra and the ureters) are working.1
Clinical Context
Videourodynamics are used to evaluate various lower urinary tract symptoms, including incontinence, overactive bladder, and urinary retention.1 They are particularly valuable in patients with complex lower urinary tract dysfunction, such as those with neurological conditions.2 This diagnostic tool allows for the assessment of bladder wall trabeculation, identification of diverticula, and determination of the presence and grade of vesicoureteral reflux.2
Videourodynamics can help identify bladder or urethral dysfunctions that contribute to lower urinary tract symptoms, aiding in precision diagnosis and treatment.1 They are also used to assess patients at risk for upper urinary tract damage.2
Patient selection for videourodynamics often includes individuals with persistent storage symptoms after initial drug therapy, or those with suspected primary bladder neck obstruction or dysfunctional voiding.3
