Title: “Retrocaval ureter or Preureteral vena cava: lest we forget this rare cause of hydronephrosis” Abstract: Retrocaval ureter or circumcaval ureter is a rare congenital abnormality arising from dysgenesis of the inferior vena cava (IVC) that results in the right ureter coursing behind and medial to the IVC. The ideal nomenclature for the anomaly is preureteral vena cava‚ keeping in mind the aberrant embryology. It can result in hydronephrosis and is a rare cause of long-standing cyclical pain

smaller organs‚ muscles‚ and cells. While the ureter and esophagus are parts of two different body systems‚ the ureter active in the urinary system and the esophagus being activated in the digestive system. Through observations from Anatomy and Physiology Revealed‚ Saladin’s fourth edition of Human Anatomy‚ and in lab observations‚ the tubes were evaluated individually and together in order to compare them. While there are several similarities between the ureter and the esophagus‚ there are a few differences

by regulating water balance and by removing harmful substances from the blood. The blood is filtered by two kidneys‚ which produce urine‚ a fluid containing toxic substances and waste products. From each kidney‚ the urine flows through a tube‚ the ureter‚ to the urinary bladder‚ where it is stored until it is expelled from the body through another tube‚ the urethra. The kidneys are surrounded by three layers of tissue: The renal fascia is a thin‚ outer layer of fibrous connective tissue that

substances will build up in our bodies and kill us. It also helps in maintaining the composition of body fluids. The Excretory System of humans is made up of 4 structures: Two kidneys‚ two ureters‚ a bladder‚ and the urethra. The kidneys act as a filter to filter the waste products from the blood‚ the ureters are tubes that transport the main waste products (urine) from the kidneys to the bladder‚ where it is stored until it is excreted out of the body through the urethra. Formation of Urea:

• Ureterocele • Ureterocele • A ureterocele is a cystic out-pouching of the distal ureter into the urinary bladder. • Affects the kidney‚ ureter‚ and bladder • An abnormality that develops during embryo development • It is present at birth but may not be discovered until later in life. • There is no known prevention for this condition • Ureterocele Background • The clinical rate of ureteroceles has been found to be approximately 1 in 4000 pediatric admissions • Occurring almost entirely

The occurrence of finding a duplex kidney (duplicated collecting system) is not uncommon. Duplicated collecting systems are almost always asymptomatic incidental findings. Duplication of a ureter might be partial or complete. The kidneys go through a complicated series before you are born. When one of those steps are missed or performed in an unusual manner it can cause an abnormality. We present a case for review in which the patient was experiencing flank pain that turned in to kidney stones

Anatomy Glomerulonephritis is inflammation of the tiny fibers in your kidneys‚ which are called glomerular. The major structure of glomerulonephritis is the kidneys‚ but the kidneys are also part of the urinary system‚ which includes the kidneys‚ the ureters‚ the urinary bladder‚ and the urethra. Every person had two kidneys and they are bean shaped and darkish red or brown in color. The kidneys are found posteriorly to the abdomen. The kidneys are embedded in a fatty pouch‚ which consists of three layers

Stratified squamous: A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Although this epithelium is referred to as squamous‚ many cells within the layers may not be flattened; this is due to the convention of naming epithelia according to the cell type at the surface. In the deeper layers‚ the cells may be columnar or cuboidal. This type of epithelium is well suited to areas in the body subject to constant abrasion‚ as it
