An Endoscopic treatment for male short segment posterior urethral stricture

Objective: To introduce a new sequential sheath urethral dilatation (SSUD) method to treat male short segment posterior urethral stricture (MSS-PUS). Methods 67 male patients who had a MSS-PUS were enrolled and randomly assigned to one of two groups: group A (SSUD) and group B (Cold knife internal urethrotomy, CIU). Baseline information, including age, diabetes status, location of urethral stricture, preoperative ultrasound post-void residual (PVR) measurement, preoperative maximum urinary flow rate (Qmax), and preoperative International Prostate Symptom Score (IPSS) were collected and compared between groups. The operation time, postoperative length of hospital stay, indwelling catheter size, success rate, operative complications, recurrence, postoperative PVR, Qmax, and IPSS were evaluated and compared between the two groups. Results There was no significant difference in the baseline data, postoperative data, the complication, recurrence rates, postoperative length of hospital stay and postoperative PVR measurements between the two groups (p > 0.05), but the difference in immediate success rate, operative time, indwelling catheter size, postoperative Qmax and postoperative IPSS was statistically significant (p < 0.05). Conclusion We introduced a new SSUD method to treat MSS-PUS. The immediate success rate, operation time, and surgical effect were better than the CID procedure.
