Quality control in urodynamics.

AIM: To review the quality and consistency of urodynamic traces collected as part of the Bladder Ultrasound Study (BUS).

METHOD: A total of 64 urodynamic traces were randomly selected and assessed for adherence to the BUS standard operating procedure based on good urodynamic practice guidelines. Assessments were undertaken of the patient's position during the filling phase, filling cystometry rate, presence of one cough per minute, presence of cough pre and post void, reliability of initial diagnosis and whether there was adequate zeroing pressures before starting the urodynamic studies.

RESULTS

Eight traces complied fully with the BUS standard operating procedure. In 52 traces, women were in the recommended filling position and 34 traces were performed at the recommended cystometry rate. In 58 traces, initial diagnoses were re-confirmed by the reviewers.

CONCLUSION

There was good consistency and adherence to urodynamic practice guidelines. Areas for improvement include adhering to the recommended filling cystometry rate and initiating cough post void.
