[A method for joining the ends of the resected urethra]

Area of Science:

• Urology
• Surgical Innovation
• Anatomical Studies

Background:

• Urethral reconstruction surgery, while recognized, has a high complication rate (3-29%).
• Existing techniques involving full-layer suturing of urethral ends are implicated in post-operative ischemia.
• Ischemia at the anastomosis site can lead to poor functional results and complications.

Observation:

• Experiments on male dogs and human cadavers demonstrated urethral ischemia due to standard suturing.
• Mathematical calculations indicated 12-16% urethral tissue ischemia with conventional methods.
• A new technique was developed to oppose and fix urethral ends using outer layers only, avoiding full-layer suturing.

Findings:

• The novel technique, involving 6 stitches on outer layers, was applied to 29 patients.
• Twenty-eight patients achieved successful micturition recovery post-surgery.
• One patient experienced a relapse due to inflammatory urethral stricture, but reoperation yielded good results. Long-term follow-up (3 months to 3 years) showed sustained positive outcomes for most patients.

Implications:

• This modified surgical approach offers a promising alternative to reduce complications in urethral reconstruction.
• Minimizing ischemia through non-full-layer suturing can improve functional recovery and patient satisfaction.
• Further research and clinical adoption of this technique could enhance the standard of care for urethral stricture disease.
