一、发病情况原发尿道癌是泌尿系中少见的肿瘤。其发病率明显低于膀胱、肾脏及男性生殖系中之睾丸和阴茎肿瘤,但原发性尿道癌在尿道恶性肿瘤中却相对多见。原发性尿道癌,女性明显多于男性。我院1961～80年共收治尿道肿瘤27例,其中良性4例,均为女性;恶性23例中经病理证实的原发性尿道癌20例,女性19例,男性1例。随着肿瘤防治的加强,原发尿道癌的发现有增加的趋势。国外有报道指出,部分原发性尿道癌曾被当作阴道癌、阴唇癌、膀胧癌、尿道肉阜、息肉、粘膜外翻而误诊。
First, the incidence of primary urinary tract cancer is a rare tumor in the urinary tract. The incidence was significantly lower than in the bladder, kidney and male reproductive system of testicular and penile tumors, but primary urethral cancer in urethral malignancies are relatively common. Primary urethral cancer, women significantly more than men. Twenty-seven cases of urethral tumors were treated in our hospital from 1961 to 1980, of which 4 were benign and all were female. Twenty cases of pathologically confirmed primary urethral carcinoma were malignant in 23 cases, 19 were female and 1 was male. With the strengthening of prevention and treatment of cancer, the detection of primary urinary tract cancer has an increasing trend. Foreign reports pointed out that some of the primary urethral cancer had been as vaginal cancer, labia majora, bladder cancer, urethral caruncle, polyps, mucosal eversion and misdiagnosis.
