To take the first step toward standardization of UDS with air-filled catheters, we present a video documenting a procedure for performing video UDS with air-filled catheters in female adults. According to The International Consultation on Incontinence (ICS), the aim of urodynamic studies (UDS) in clinical practice is to evaluate a patient's lower urinary tract function with at least 1 complete and representative filling-voiding-post-voiding cycle by testing with relevant pressures and flowmetry.1 International guidelines state that UDS is preferably performed with fluid-filled catheters.2,3 However, although air-filled catheters are widely used, further research is needed before these catheters can be recommended for routine clinical use.4 To our knowledge, no guide on how to perform UDS with air-filled catheters has been published.


The UDS was conducted according to local protocol. The ICS recommendations mentioned above were used as a template for this protocol. Intravesical, intraurethral, and abdominal pressure were measured. The cysto-urethrometry filling cycle and pressure-flow study were performed in sitting position. Fluoroscopy was performed during filling and voiding phase at fixed points. Before starting the filling cycle, the patient was verbally instructed with visual aids (Fig. 1) to report bladder sensation. Filling rate was 10% of the largest voiding flow rate reported on the frequency volume chart. Initial baseline pressure was measured, and a cough pressure response test was performed.


Our procedure for video UDS with air-filled catheters in a female adult was demonstrated in an instruction video.


An instruction video on a standardized UDS with air-filled catheters in female adults is presented to take the first step toward standardization and for the benefit of health-care workers performing such tests.
