Urology (from Greek οὖρον ouron "urine" and -λογία -logia "study of"), also known as genitourinary surgery, is the branch of medicine that focuses on surgical and medical diseases of the male and female urinary tract system and the male reproductive organs. The organs under the domain of urology include the kidneys, adrenal glands, ureters, urinary bladder, urethra, and the male reproductive organs (testes, epididymis, vas deferens, seminal vesicles, prostate, and penis).
The urinary and reproductive tracts are closely linked, and disorders of one often affect the other. Thus, a major spectrum of the conditions managed in urology exists under the domain of genitourinary disorders. Urology combines the management of medical (i.e., non-surgical) conditions, such as urinary tract infections and benign prostatic hyperplasia, with the management of surgical conditions such as bladder or prostate cancer, kidney stones, congenital abnormalities, traumatic injury, and stress incontinence.
Urology has traditionally been on the cutting edge of surgical technology in the field of medicine, including minimally invasive robotic and laparoscopic surgery, laser-assisted surgeries, and a host of other scope-guided procedures. Urologists are trained in open and minimally invasive techniques, employing real-time ultrasound guidance, fiber-optic endoscopic equipment, and various lasers in the treatment of multiple benign and malignant conditions. In addition, urologists are pioneers in the use of robotics in laparoscopic surgery. Urology is closely related to (and urologists often collaborate with the practitioners of) oncology, nephrology, gynaecology, andrology, pediatric surgery, colorectal surgery, gastroenterology, and endocrinology.
Urology is one of the most competitive and highly sought-after surgical specialties for physicians, with new urologists comprising less than 1.5% of United States medical school graduates each year. In Canada, urology is an exceedingly difficult specialty to match, with less than 0.1% of the position dedicated to it.
