妇科肿瘤放疗所致尿瘘处理

妇科肿瘤放射治疗后尿瘘的发生率极低，但是严重影响患者的生存质量。放射性尿瘘可能与放疗方式、剂量、术后放疗、腔内近距离放疗及放疗技术等多种因素有关。目前放射性尿瘘以手术治疗为主，经腹腔利用带蒂皮瓣修复、尿流改道等适用于治疗放射性尿瘘。放射性尿瘘的预防措施在于严格把握妇科肿瘤手术适应证、改进放疗技术、合理应用腔内近距离放疗等。

Management of radiation-induced urinary fistula in patients with gynecological tumor.

Abstract: The incidence of urinary fistula rate is very low in patients with gynecological tumor after radiation therapy，but it influences the quality of life seriously. Aspects as radiation injury, dose, postoperative radiotherapy, brachytherapy and radiation techniques impact the incidence of fistula. The operation treatment is the main treatment method at present. The abdominal approach repair by using pedicle flap and urinary diversion are applicable for radiation-induced urinary fistulas. Methods as strictly control surgical indications, improved radiotherapy techniques, reasonable application of brachytherapy may reduce radiation-induced urinary fistulas.
