Application of multihole U-shaped drainage stent in complex posterior urethra surgery

Objective To study a method for using a new drainage stent following complex posterior urethral operation. Methods Fifty-five patients,15 of whom had complex posterior urethrorectal fistula, 35 had complex posterior stricture or a-tresia, and 5 had bladder exstrophy, received surgical treatment, after which multihole U-shaped drainage stent was applied. Results All the patients were normal in micturition and no complications occurred during the follow-up period lasting for 1 to 10 years. Conclusion Multihole U-shaped drainage stent performs the functions of both stenting and drainage, and is applica-ble in complex posterior urethral surgery.
