BACKGROUND: Although uroflowmetry is a widely used diagnostic test, reference values of uroflowmetry parameters in women are lacking making it difficult to interpret the test results.

AIM: To quantify the range of results in uroflowmetry parameters in healthy women based on a systematic review.

METHODS: A search was made in the International Continence Society standardization articles, PubMed, Embase and the Cochrane Library (from inception to 27 February 2014). Studies on uroflowmetry in healthy women were included. The selected articles were examined using a critical appraisal process based on the QUADAS-2 tool and the Critical Appraisal Skills Program.

RESULTS: Mean values of uroflowmetry parameters in healthy women (mean age 37.1 years) were: voided volume (VV) 338 ml (SD 161), maximum flow rate (Qmax) 23.5 ml/s (SD 10), average flow rate (Qave) 13 ml/s (SD 6), postvoid residual (PVR) 15.5 ml (SD 25), voiding time (VT) 29 sec (SD 17), and time to maximum flow rate (time to Qmax) 8 sec (SD 6). Qmax was dependent on VV. There was no clear relationship between Qmax and age, and no correlation between parity and Qmax. A normal shape of the uroflowmetry curve was seen in 70-80% of the flows.

CONCLUSION: This systematic review provides an overview of the range of results of uroflowmetry parameters in healthy women. Neurourol. Urodynam. 36:953-959, 2017. © 2016 Wiley Periodicals, Inc.
