Ureters are the ducts that move urine along from the kidneys to the urinary bladder, also called cloaca.
Renal Colic Attack From Blocked UretersUreterolithiasis can cause a painful condition called a renal colic attack in which either one or both of the ureters become blocked by kidney stones.
Renal colic due to ureterolithiasis or kidney stones is often described as the strongest and most unbearable pain a person has ever felt in their lives.
75 to 85 percent of kidney stones or calculi are calcium stones. About half of ureterolithiasis or caluli are composed of both oxalate and calcium phosophate.
