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

We herein report the clinical statistics on new outpatients over five years from 1994 at our hospital. The average number of new outpatients per year was 8,534.4 (8,366-8,658) and there was only a slight variation in the number over the last five years. The male to female ratio was 1.61:1. Twenty-one percent of the outpatients were referred to us by other sources. The representative operations on outpatients were circumcision, vasectomy, resection of condylomas and resection of caruncles. A statistical study was made on new outpatients according to the international classification of disease. There were 197.0 (2.3%) malignant urogenital tumors per year. There was a tendency for sexually transmitted diseases to increase over the last five years. In males, the major diseases were upper urinary tract stones (23-27%), benign prostatic hypertrophy (19-26%) and prostatitis (15-24%). In females, they were cystitis (57-59%), upper urinary tract stones (17-18%) and neurogenic bladder (3-4%). We conclude that our hospital plays a major role as a private urological hospital.
