A urologic oncologist is a physician with special training in diagnosing and treating cancers of the male and female urinary tract and the male reproductive organs. These organs include the bladder, kidneys, prostate, penis and testicles. Urological cancers are relatively common, with prostate, bladder and kidney cancers among the 10 most common cancers diagnosed in the India.

Endourology refers to a specific area in urology in which minimally invasive surgical techniques are used to see into the urinary tract and perform surgery. Kidney stones are extracted, or fragmented, using small endoscopes and instrumentation through areas such as the urethra, bladder and ureter.

The kidneys are two reddish-brown bean-shaped organs found in vertebrates. They are located on the left and right in the retroperitoneal space, and in adult humans are about 12 centimetres (4 1⁄2 inches) in length. They receive blood from the paired renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter, a tube that carries excreted urine to the bladder.

Bladder, is a hollow muscular organ in humans and other vertebrates that stores urine from the kidneys before disposal by urination. In the human the bladder is a hollow distensible organ that sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra. The typical human bladder will hold between 300 and 500 ml (10.14 and 16.91 fl oz) before the urge to empty occurs, but can hold considerably more.

The prostate is a gland that produces some of the fluid that carries sperm during ejaculation. The prostate gland surrounds the urethra, the tube through which urine passes out of the body. An enlarged prostate means the gland has grown bigger. Prostate enlargement happens to almost all men as they get older.

Pediatric urology is a surgical subspecialty of medicine dealing with the disorders of children's genitourinary systems. Pediatric urologists provide care for both boys and girls ranging from birth to early adult age. The most common problems are those involving disorders of urination, reproductive organs and testes.
