OBJECTIVE To critically evaluate the use of uroflowmetry (UF) in a large urethral stricture disease cohort as a means to monitor for stricture recurrence. MATERIALS AND METHODS This study included men that underwent anterior urethroplasty and completed a study-specific follow-up protocol. Pre- and postoperative UF studies of men found to have cystoscopic recurrence were compared to UF studies from successful repairs. UF components of interest included maximum flow rate (Qm), average flow rate (Qa), and voided volume, in addition to the novel post-UF calculated value of Qm minus Qa (Qm-Qa). Area under the receiver operating characteristic curves (AUC) of individual UF parameters was compared. RESULTS Qm-Qa had the highest AUC (0.8295) followed by Qm (0.8241). UF performed significantly better in men ≤40 with an AUC of 0.9324 and 0.9224 for Qm-Qa and Qm respectively, as compared to 0.7484 and 0.7661 in men >40. Importantly, of men found to have anatomic recurrences, only 41% had a Qm of ≤15 mL/s at time of diagnostic cystoscopy, whereas over 83% were found to have a Qm-Qa of ≤10 mL/s. CONCLUSION Qm rate alone may not be sensitive enough to replace cystoscopy when screening for stricture recurrence in all patients, especially in younger men where baseline flow rates are higher. Qm-Qa is a novel calculated UF measure that appears to be more sensitive than Qm when using UF to screen for recurrence, as it may be a better numerical representation of the shape of the voiding curve.

“…4,5 Evaluation can involve any combination of cystourethroscopy, flow studies, retrograde urethrography or other imaging studies, and patient history. 4,6 Our objective was to compare the pre-and postoperative patient-reported outcomes to better describe patients' perception of success, considering the urinary bother scores, quality of life, and overall erectile function for each patient. Concurrently, we obtained objective data using cystoscopy, establishing a minimum of 17F as the standard objective definition of success.…”

“…El-Kassaby and Sa reported three-dimensional spiral computed tomography/cysto-urethrography (CTCUG) and reconstruction pictures could provide physician preoperative evidence for better surgical planning and consequently better results of posterior urethral stricture [5,6]. Ultrasonography has got increased attention in the diagnosis of urethral stricture due to its characters such as presenting direct and real-time images as well as accurate information of exterior and interior structures of urethral lumen during urethral operations with good repeatability and without X-ray radiation [7].…”

Abstract. Urethral ultrasonography is non-invasive and able to indicate the urethral lumen clearly, as well as the surrounding tissues of the posterior urethra, without contrast agent or X-ray irradiation. In this paper, we evaluate the reliability of urethral ultrasonography in the diagnosis of dysuria following bipolar transurethral plasma kinetic prostatectomy (TUPKP). A total of 120 benign prostate hyperplasia (BPH) patients with dysuria undergoing TUPKP were enrolled in this study, with a mean age of 72.8 years. All the patients received urethral ultrasonography, urethroscopy and bladder neck urethra stenosis oulectomy. Among the 120 cases, there were 22 cases of bladder neck closure, 20 bladder orifice stricture, 60 urethral stricture, 10 prostate remnants, 2 calculi in prostatic urethra, 4 dysfunction of bladder detrusor muscle and 2 flap of internal urethral orifice. χ 2 -test was used for the comparison of ultrasonography and urethral cystoscopy in the diagnosis of dysuria following TRPKP, and no significant difference was found between two diagnostic tools (χ 2 = 0.94, P > 0.05). Urethral ultrasonography is a reliable and minimally invasive diagnostic tool for dysuria following TUPKP and is conducive to early treatment of dysuria following prostatectomy.
