He was diagnosed as “urethral injury” at the local hospital. After the operation, he felt no significant improvement in urination and urine dripped by force. The patient had erectile dysfunction but still had mild erection ◆Diagnosis and treatment > Posterior urethral stricture, elective end-to-end urethral anastomosis was performed. ◆Follow-up and discussion > One month after the operation, the urethral catheter was removed and urination was clear, and erectile function was still present. End-to-end urethral anastomosis with non-disconnected urethral corpus cavernosum is a new surgical procedure developed by Prof. Yuemin Xu during his long practice of urethral surgery, which has not been reported in China. This surgical procedure can preserve the complete structure of the urethral corpus cavernosum to the greatest extent, thus preserving the sexual function of the patient to the greatest extent. As the first doctor of Prof. Yuemin Xu, Deputy Director Chao Li has been transferred from the Sixth Hospital to Shanghai Tongji Hospital, and nearly 10 patients have been treated with this surgical method, and all of them have recovered satisfactorily after the operation. This surgical method is worthy of reference and promotion.
