Urethroplasty is currently a standard method of urethral stricture treatment. A uroflowmetry is typically used in the postoperative assessment of patients. The test is noninvasive, but it poses an additional cost and its proper performance may be troublesome. 
The aim of our study was to assess if the patient-reported outcome measure (PROM) may replace uroflowmetry in the follow-up after urethroplasty.

A group of 21 men treated with urethroplasty for urethral stricture was included into the study. In the assessment of micturition, both before and after the operation, we used uroflowmetry and a translated questionnaire dedicated to patients with urethral stricture (PROM) [1]. In the Wilcoxon test, we compared the Qmax value and PROM result before and after the treatment. Using the Spearman's rank correlation coefficient we correlated the postoperative Qmax and PROM results.

A mean Qmax value increased after the treatment from 3.7ml/s to 15.4ml/s (p=0,0015), and a mean PROM result decreased from 22.7pts to 9.1pts (p=0,0002). The postoperative results of PROM had a correlation with postoperative Qmax values (R=-0,5218, p=0,0153).

The PROM is a sensitive tool in the assessment of micturition in patients treated with urethroplasty, and its results correlate with Qmax values.

The patient-reported outcome measure may replace uroflowmetry in the postoperative assessment of men treated with urethroplasty.
