Urethral cancer is the only genitourinary neoplasm with a predilection for women, the ratio being 4:1. The histologic type depends on the cells of origin. Squamous-cell carcinoma predominates, with adenocarcinoma and transitional-cell carcinoma being less common and undifferentiated carcinoma, malignant melanoma, mixed tumors, clear-cell carcinoma, and cloacogenic carcinoma accounting for the remaining lesions. The authors describe the various options for the management of low-stage and high-stage cancers and of cancers arising in urethral diverticula.
尿道癌是唯一一种女性比男性更易患的泌尿生殖系统肿瘤，男女患病比例为4:1。组织学类型取决于肿瘤的起源细胞。鳞状细胞癌最为常见，腺癌和移行细胞癌相对少见，未分化癌、恶性黑色素瘤、混合瘤、透明细胞癌和泄殖腔源癌则占其余病例。作者描述了低分期和高分期尿道癌以及尿道憩室癌的各种治疗选择。
