Abstract:
OBJECTIVE:To develop the visual uroflow scale (VUS), analyze the relationship of VUS score and index of free uroflowmetry, assess urination function preliminarily and improve the work efficiency in the clinic.
METHODS:Male lower urinary tract symptoms (LUTS) patients, who attended the Department of Urology in Peking University People's Hospital from March 2016 to March 2017, were assessed for their urination function according to the Visual Uroflow Scale without help from clinicians before undertaking a free uroflowmetry test. And afterwards, a free uroflowmetry was undertaken, and variables including maximal flow rate (Qmax), the average flow rate (Qave) and voiding volume (VV) was obtained. During the study, 124 cases were collected and 53 cases met the inclusion and exclusion criteria and were included in the study cohort. The Spearman correlation analysis was used for analyzing the correlation of VUS scores with free uroflowmetry variables and age. The validity of VUS was evaluated.
RESULTS:Most of the patients could choose the very figure matched with self-condition by first instinct without any help from the clinician. The data were analyzed by Spearman correlation analysis. In the present study, voiding time was positively correlated with the VUS score (correlation coefficient, 0.62, P < 0.05). In the present cohort, the patients chose the third and fourth figures to take longer time to urinate, implying worse LUTS situation. Flow time and VUS scores were positively correlated (correlation coefficient, 0.61, P < 0.05). The patients with higher VUS scores would spend more time on urinate, no matter how long urinary hesitation was. Both Qmax and Qave were negatively correlated with the VUS score (correlation coefficient －0.54, －0.62, P < 0.05). The study illustrated that the VUS score suggested that the Qmax basically and further reflected the urination function. And its relationship to age revealed the decreased urination function of aging male, which had reached a consensus.
CONCLUSION:Development of VUS has helped the clinician assess the urination function preliminarily at the first time. Patients are assessed for a VUS score before getting surgery or receiving the drug for treatment, and can be re-assessed after. The VUS score can provide an objective quantitative basis to evaluate the treatment efficacy. In addition, considering that it is convenient, timesaving and easy to understand, the VUS is available for follow-up.
