[Clinical statistics at the urological clinic of Sanjukai Hospital--statistics on new outpatients during the last five years].

We report the clinical statistics of new outpatients for five years since 1989 at our hospital. The average total number of new outpatients in a year was 8309.8 (8122-8691) and new outpatients tended to show little change. The male to female ratio was 1.57:1, and 24.3% of the outpatients were referred to us by others sources. The representative operations on outpatients were circumcision, vasectomy, resection of condyloma and resection of caruncle. A statistical study was made on new outpatients according to the international classification of disease. There were 140.6 (1.97%) malignant urogenital tumors per year. Sexually transmitted diseases showed a tendency to increase for the last five years. In males the major disease was upper urinary tract stone (21-24%), prostatistis (21-24%) and benign prostatic hypertrophy (17-20%) and in females they were cystitis (58-61%), upper urinary tract stone (15-17%) and pyelonephritis (3-4%). We conclude that our hospital plays a major role as a private urological hospital.
