Urine

The ureters are tubes made of smooth muscle fibers that propel urine from the kidneys to the urinary bladder.
Urine flows from the kidneys through the ureters to the urinary bladder.

Kidney

kidneysrenalkidney disorder
The ureters are tubes made of smooth muscle fibers that propel urine from the kidneys to the urinary bladder.
Each kidney is attached to a ureter, a tube that carries excreted urine to the bladder.

Urinary bladder

bladderfundusintravesical
The ureters are tubes made of smooth muscle fibers that propel urine from the kidneys to the urinary bladder. In females, the ureters pass through the mesometrium and under the uterine arteries on the way to the urinary bladder.
Urine enters the bladder via the ureters and exits via the urethra.

Renal pelvis

pyelo-kidney pelvispelvic
The ureters are tubular structures, approximately 3 mm in adults, that pass from the pelvis of each kidney into the bladder.
The renal pelvis or pelvis of the kidney is the funnel-like dilated part of the ureter in the kidney.

Vesicoureteral reflux

Defluxrefluxreflux uropathy
At the entrance to the bladder, the ureters are surrounded by valves known as ureterovesical valves, which prevent vesicoureteral reflux (backflow of urine).
Vesicoureteral reflux (VUR), also known as vesicoureteric reflux, is a condition in which urine flows retrograde, or backward, from the bladder into the ureters/kidneys.

Ureteric plexus

ureteric
The ureters are richly supplied by nerves that form a network of nerves, the ureteric plexus that lies in the adventitia of the ureters.
The ureteric plexus is a nerve plexus covering and innervating the ureter.

Internal iliac artery

internal iliac arterieshypogastric arteryiliac arteries
The following are relations of the artery at various points: it is posterior to the ureter, anterior to the internal iliac vein, the lumbosacral trunk, and the piriformis muscle; near its origin, it is medial to the external iliac vein, which lies between it and the psoas major muscle; it is above the obturator nerve.

Ovarian artery

ovarian arteriesovarian vesselsovarian
It can be found in the suspensory ligament of the ovary, anterior to the ovarian vein and ureter.

Urinary system

urinary tracturinaryrenal system
Congenital disorders of the ureter and urinary tract affect 10% of infants.
The urinary system, also known as the renal system or urinary tract, consists of the kidneys, ureters, bladder, and the urethra.

Epithelium

epithelialepithelial cellsepithelial cell
The transitional epithelium may appear as a layer of column-shaped cells when relaxed, and of flatter cells when distended.

Common iliac artery

common iliac arteriescommon iliaciliac
Here, they cross in front of the common iliac arteries.
Their terminal bifurcation is crossed anteriorly by the ureters.

Kidney stone disease

kidney stonekidney stonesnephrolithiasis
If a stone grows to more than 5 mm, it can cause blockage of the ureter, resulting in severe pain in the lower back or abdomen.

Renal artery

renal arteriesrenalarteries of the kidneys
Before reaching the hilus of the kidney, each artery divides into four or five branches; the greater number of these (anterior branches) lie between the renal vein and ureter, the vein being in front, the ureter behind, but one or more branches (posterior branches) are usually situated behind the ureter.

Mesometrium

In females, the ureters pass through the mesometrium and under the uterine arteries on the way to the urinary bladder.
The ureter is among the structures found in the mesometrium.

Uterine artery

uterine arteriesuterineuterine vessels
The ureter is injured in 0.2 per 1,000 cases of vaginal hysterectomies and 1.3 per 1,000 cases of abdominal hysterectomies, near the infundibulopelvic (suspensory) ligament or where the ureter courses posterior to the uterine vessels, near the cardinal ligament.
It travels to the uterus, crossing the ureter anteriorly, to the uterus by traveling in the cardinal ligament.

Ureteral cancer

ureters
Cancer of the ureters is known as ureteral cancer and may have several causes.
Ureteral cancer is cancer of the ureters, muscular tubes that propel urine from the kidneys to the urinary bladder.

Hydronephrosis

Bilateral hydronephrosisBlockage of urine flowdilation of the kidney
Failure of the ureteropelvic junction to become patent during development is the most frequent cause of bilateral hydronephrosis, particularly in male neonates.
Common causes of upper tract obstruction include obstructing stones and ureteropelvic junction (UPJ) obstruction caused by intrinsic narrowing of the ureters or an overlying vessel.

Testicular artery

internal spermatic arteryinternal spermatic vesselsspermatic vessels
The internal spermatic artery supplies one or two small branches to the ureter, and in the inguinal canal gives one or two twigs to the Cremaster.

Urinary tract infection

cystitisurinary tract infectionsbladder infection
This condition can be one cause of chronic urinary tract infections, particularly in children.
In children UTIs are associated with vesicoureteral reflux (an abnormal movement of urine from the bladder into ureters or kidneys) and constipation.

Schistosomiasis

bilharziabilharziasisantischistosomal
If the cancer is a squamous cell carcinoma, this is often associated with a change in the type of cells lining the ureters as a result of chronic inflammation associated with schistosomiasis or stones.
The worms of S. haematobium migrate to the veins around the bladder and ureters.

Ureteric bud

metanephric
The ureters develop from the ureteric buds, which are outpuchings from the mesonephric duct.

Ureteral branches of renal artery

The ureteral branches of renal artery are small branches which supply the ureter.

Superior vesical artery

Other branches supply the ureter.

Pyeloplasty

Anderson-Hynes pyeloplasty
Pyeloplasty, which involves excision of the stenotic section and creation of a new junction, is the most common and effective treatment for this problem.
Pyeloplasty is performed to treat an uretero-pelvic junction obstruction if residual renal function is adequate.
