There are different surgical options for the treatment of anterior stricture diseases such as anastomotic repair, substitution urethroplasty and two stage procedures. The choice of the adequate technique must be based on a correct urethral stricture selection (aetiology, length, previous treatments, local factors). The urethroplasty failures are generally secondary to incorrect selection or execution of the operations and sometimes to spongiofibrosis relapse or prolonged tessutal ischemia. End-to-end anastomosis is the treatment of choice for strictures, particularly post traumatic, of the bulbous urethra no longer than 2 cm. The dorsal roof-strip anastomosis is indicated for bulbar urethral strictures longer than 2 to 3 cm. It is a combined end-to-end and substitution urethroplasty technique.
对于诸如吻合口修复、替代尿道成形术和两阶段手术等前尿道狭窄疾病的治疗，有不同的手术选择。合适技术的选择必须基于正确的尿道狭窄评估（病因、长度、既往治疗、局部因素）。尿道成形术失败通常继发于手术选择或实施不当，有时也继发于海绵体纤维化复发或组织长时间缺血。端端吻合术是治疗球部尿道狭窄（尤其是创伤后）且长度不超过2厘米的首选方法。背侧屋顶条带吻合术适用于长度超过2至3厘米的球部尿道狭窄。它是一种端端吻合与替代尿道成形术相结合的技术。
