Uroflowmetry, video-urodynamic and operative images of the two cases. (A-C) First case scenario. (A) Q-tip test; (B) The VUDS showing multiple stress leak with abdominal leak point pressure of 40 cmH2O (1 cmH2O=0.098kPa); (C) Postoperative uroflowmetry showing a bell-shaped curve with voided volume 170 mL, Qmax 31.5 mL/s, and negligible PVR; (D-F) Second case scenario. (D) The VUDS showing high pressure poor flow voiding with Qmax 3 mL/s, Pdet@Qmax 63 cmH2O, and PVR 200 mL (though bladder neck funnelling is poor, a streak of contrast reached till proximal urethra); urethroscopy showing dense fibrous whitish ring at the level of proximal to mid urethra; (E) The post urethroplasty VUDS showing no urinary flow at the voiding phase with maximum detrusor pressure of 106 cmH2O and no bladder neck funnelling suggestive of primary bladder neck obstruction; (F) Postoperative uroflowmetry showing a bell-shaped curve with voided volume 170 mL, Qmax 22 mL/s, and negligible PVR. VUDS, video-urodynamic study; Qmax, maximum urinary flow; Pdet@Qmax, detrusor pressure at maximum urinary flow; PVR, post-void residual urine.
