AB028. The repair and reconstruction of urethral stricture

Urethral stricture is still a challenging field in urology. Despite the varied procedures to treat this disease at present, no one existed approach can be clearly stated to be superior over another. Among the procedures, simple dilation and direct vision internal urethrotomy are more commonly suggested only for short urethral stricture (<1 cm, soft and no previous intervention). Currently, urethroplasty using buccal mucosa or penile skin are the most widely adapted techniques in clinic and have met great success. But some complications such as donor site morbidity still remains problems to be solved. Tissue engineering technique is considered as a promising solution for urethral reconstruction, but still need further investigation, and the stem cell therapy also mandates further work in the future.
