Urology is a surgical speciality that addresses male and female diseases of the urinary tract, as well as male reproductive system disorders. Urology is a part of health care that deals with diseases of the male and female urinary tract (kidneys, ureters, bladder and urethra). It also deals with the male organs that are able to make babies (penis, testes, scrotum, prostate, etc.). Since health problems in these body parts can happen to everyone, urologic health is important.
A urethral stricture is a narrowing of the urethra caused by injury, instrumentation, infection and certain non-infectious forms of urethritis.
