註釋
Radiotherapy-induced urethral strictures (RIUS) decrease quality of life and present a great challenge for surgical reconstruction, especially due to proximal location, compromised vascular supply, and poor wound healing. It is unclear whether urethroplasty is an option in cases with stricture resulting from exposure to pelvic radiation. We review the pathophysiology, diagnostic workup, and disease-specific aspects of RIUS. Furthermore, we discuss several management alternatives such as excision and primary anastomosis, as well as techniques for open reconstruction with flaps. The most extensive techniques in the treatment of strictures include, for example, those using gracilis muscle flaps, as they can involve periurethral tissue to provide sufficient vascularity for excellent post-surgery urethral healing. In brief, RIUS represent a significant challenge. In carefully chosen patients, urethroplasty should be considered as a feasible and durable treatment. However, medical practitioners should always take into consideration that the results of urethroplasty in RIUS are not comparable to urethroplasties without a radiation background.
