Urethral stricture is an ancient disease and people have gone through a long process of understanding urethral stricture. With the process of modernization, especially with the development of infrastructure such as mineral development and building construction, urethral stricture caused by trauma has become more and more common. Given the differences in the level of diagnosis and treatment at hospitals at all levels, their treatment measures are also varied. Urethral strictures caused by trauma are mostly seen as posterior urethral strictures. The so-called posterior urethra is the segment of the urethra that runs from the bulb of the urethra toward the bladder. Generally speaking, patients cannot feel their posterior urethra themselves. The fact that the posterior urethra is located so deeply also makes it difficult for physicians to treat the condition. Considering the combined injuries of the patients, injured patients are mostly seen in primary care in the early stages. The treatment measures are no more than urethral conduction and the second stage of cystostomy management. After early urethral conference for various reasons more patients will experience difficulty in urination after removal of the urethral tube or even progressive inability to urinate. Some primary care physicians choose urethral dilatation to treat early dyspareunia, however, due to technical reasons, blind urethral dilatation leading to re-injury to the urethra is common and even leads to the patient having two posterior urethra, that is, long-term inadvertent dilatation leading to the formation of a false tract. I see many of these patients in my clinic, and they require a repeat urethral stricture scar resection and anastomosis to achieve a better outcome. The difficulties of reoperation are also great, such as the large amount of local scarring of the dissected urethra and the long distance of the dissected urethra. However, these challenges also present opportunities for the development of urethral anastomosis techniques for urologists. Our experience confirms that anastomosis of long segments of the posterior urethra with atresia or defects is possible with satisfactory results. We can achieve a tension-free anastomosis of the urethra with a longitudinal penile cavernotomy, partial excision of the pubic bone or even a whole excision. Decades of experience have confirmed that this procedure, although challenging, is a smooth process with definitive results. Therefore, patients with posterior urethral stricture are advised to dilate cautiously and operate as early as possible to benefit from early and unobstructed urination.
