Urethroplasty after radiation therapy for prostate cancer

Area of Science:

• Urology
• Oncology
• Reconstructive Surgery

Background:

• Radiation therapy for prostate cancer can lead to urethral stricture.
• Urethral stricture significantly impacts quality of life for affected men.

Purpose of the Study:

• To evaluate the outcomes of urethroplasty in men with radiation-induced urethral stricture.
• To identify factors influencing treatment success.

Main Methods:

• Retrospective review of 29 patients undergoing urethroplasty for post-radiation stricture (June 2004-May 2010).
• Data collected included patient demographics, prior radiation type, stricture characteristics, and surgical technique.
• Success defined as no requirement for repeat surgical intervention, with clinical and imaging follow-up.

Main Results:

• The overall success rate for urethroplasty was 90% with a median follow-up of 40 months.
• Anastomotic urethroplasty (76%) was the most common procedure for strictures primarily in the bulbar and membranous urethra.
• Recurrence occurred between 6-16 months post-surgery.

Conclusions:

• Urethroplasty, using various techniques, is a viable treatment for radiation-induced urethral strictures.
• Further research is necessary to confirm the long-term durability of these reconstructive procedures.
