With the combination of two operative techniques: septotomy of the penile corpus cavernosum and partial chiseling of the subpubic rim, not only is the surgical field exposed clearly, but also the route of the posterior urethral anastomosis is shortened. The purpose is: 1. The resection of the inferior pubic rim and the free distal urethra are completed in one perineal incision, which makes up for the defect that the simple perineal route cannot deal with complex posterior urethral strictures of more than 4 cm, and reduces the surgical trauma due to the long urethral defect that needs to go through the pubic route; 2. After excision of the inferior pubic rim, the distal urethra can be passed through the septum of the penile corpus cavernosum at the same time, or the distal urethra can be passed through the foot of the penile corpus cavernosum on one side, and then through the excised inferior pubic rim, and the urethra can be concealed in the space, which can shorten the distance between the anterior and posterior urethra by about 4 to 5 cm and basically achieve a tension-free anastomosis. It also avoids the phenomenon of penile shortening due to excessive freeing of the distal urethra; 4. In case of failure of this pathway, posterior urethral surgery can still be performed later through the transcubital pathway; 5. One of the keys to end-to-end urethral anastomosis is adequate excision of the scar tissue around the urethra up to the normal healthy urethral mucosa. As the cases involved in this study had severe periurethral scars and long resections, the above two techniques can ensure a tension-free anastomosis of the urethra in most patients.
