Abstract

A chromosomal study was performed in a total of 162 urological patients during past 2$2{\frac{1}{2}}$ years (Feb. 1984 - Aug. 1986). Of these 78(48%) patients had abnormal chromosome complements. Among all patients with chromosome abnormalities, 88% (69/78) had aberrations of chromosome number, 8% (6/78) had aberrations of chromosome structure and 4% (3/78) had aberrations of both. 90% (65/72) of numerical abnormality was Klinefelter's syndrome and the structural abnormality rate (5.6%, 9/162) was less than that (6.99%) of general population. The chromosomal study was mandatory for the detection of intersex in small testes or hypospadias with cryptorchism or clitoromegaly or bilateral cryptorchism. But unilateral cryptochism or hypospadias with normal scrotal testes was not thought to be indication of the chromosomal study if the external genitalia are otherwise quite normal.
