For urinary systems of other vertebrates, see Urinary systems of birds, urinary systems of reptiles, and urinary systems of amphibians.

Urine is excreted through the renal papillae into the calyces and then into the pelvis, ureter, and bladder. [62] [28] Then it is excreted outside through the urethra. [64] In monotremes, the ureters open into the urogenital sinus, which is connected to the urinary bladder and cloaca, [65] and urine is excreted into the cloaca instead of the ...
Urology addresses diseases of kidney (and urinary tract) anatomy: these include cancer, renal cysts, kidney stones and ureteral stones, and urinary tract obstruction. [7] The word “renal” is an adjective meaning “relating to the kidneys”, and its roots are French or late Latin. Whereas according to some opinions, "renal" should be ...
The ureters are muscular ducts that propel urine from the kidneys to the urinary bladder. In the human adult, the ureters are usually 25–30 cm (10–12 in) long. In humans, the ureters arise from the renal pelvis on the medial aspect of each kidney before descending towards the bladder on the front of the psoas major muscle. The ureters cross ...
It is classically described that there are three sites in the ureter where a kidney stone will commonly become stuck: where the ureter meets the renal pelvis; where the iliac blood vessels cross the ureters; and where the ureters enter the urinary bladder, [9] however a retrospective case study, which is a primary source, of where stones lodged ...
Generally, urine produced by the cortex and medulla drains from the papillae into the calyces, and then into the renal pelvis, from which urine exits the kidney through the ureter. [7] [10] Nitrogen-containing waste products are excreted by the kidneys in mammals mainly in the form of urea. [11] The structure of the kidney differs between ...
The genitourinary system, or urogenital system, are the sex organs of the reproductive system and the organs of the urinary system. [1] These are grouped together because of their proximity to each other, their common embryological origin and the use of common pathways.
