Conventional urodynamics (UDS) has its disadvantages. It is—
• Prone to artifacts due to a number of factors
• Requires a laboratory setting of the test with the patient having to void on demand
• Based on rapid bladder filling by an indwelling catheter
• Can overestimate decreased bladder compliance and underdiagnose detrusor overactivity in up to 50% of cases
Ambulatory urodynamics (AUDS) has become an established method of investigating lower urinary tract function in a more physiological manner, by enabling natural bladder filling and allowing the patient to undertake their normal activities to provoke troublesome urinary symptoms.
