Background
Urology is a medical science that specializes in the male and female urinary tracts and the male reproductive system and is mainly subdivided from surgery. The male urinary and reproductive systems are inseparable, while the female urinary tract is open to the external genitalia. In both men and women, the urinary tract and the genital tract are closely related and the diseases of the two often affect each other. Urology can be further subdivided into various sub-disciplines such as urology oncology, urinary calculus, micturition disorder, pediatric urology, sexual dysfunction, male infertility, and the like. The urological diagnosis and treatment range is as follows: prostatitis, prostatic hyperplasia, prostatic cancer, urinary system infection (urethritis, mycoplasma infection, chlamydia infection, gonorrhea, non-gonococcal urethritis, etc.); renal, ureteral, bladder cancer; urinary surgical diseases such as urinary incontinence.
