Detection of urological and male genital tumors diagnosed in Beijing Hospital 1995 - 2004

Abstract

To investigate the diagnostic condition of urological and male genital tumors in Beijing Hospital during the period 1995 - 2004. The clinical data of 1245 patients diagnosed as with urological and male genital tumors that were hospitalized in the Department of Urology, Beijing Hospital from 1 January 1995 to 31 December 2004, 957 males and 288 females, were analyzed retrospectively. The 1245 with urological and male genital tumors accounted for 20.96% of the patients hospitalized in the Department of Urology of this hospital in the same period. The commonest malignancies included transitional cell carcinoma of bladder (n = 387), carcinoma of prostate (n = 271), and clear cell carcinoma of kidney (n = 250). The detected numbers of cases of these three kinds of malignancies increased year by year. The ratio of metastatic carcinoma in prostate and kidney decreased with each passing year. Before 1999 75.48% of the patients with prostate carcinoma visited the hospital because of low urinary tract symptom (LUTS), and only 12.48% because of abnormalities discovered during physical examination, However, after 2000 the percentage of the prostate carcinoma patients who visited the hospital because of LUST deceased to 54.44%, and those because of abnormalities discovered during physical examination increased to 40.99% (P < 0.01). The improvement of diagnostic methods has changed the condition of tumor diagnosis in recent years.
