Hydronephrosis “Hydronephrosis is the swelling of a kidney due to buildup of urine. This happens when the kidney cannot drain urine from kidney to bladder because of a blockage or obstruction”. It is not a disease and can affect people of any age. Hydronephrosis is sometimes spotted in unborn babies during routine pregnancy ultrasound scan. Treatment depends on the severity and condition of the kidney. Swelling can occur in one or both kidneys. http://www.medfriendly.com/hydronephrosis.html
• It is estimated that one in 100 people have hydronephrosis affecting one kidney.
• Less people have hydronephrosis affecting both kidneys.
• In approximately 2% of all ultrasounds

When the body is ready to remove these fluids (urine) is first collected in a small part of the kidney (renal pelvis) additional to the kidneys the urinary tract consists of two ureters, the bladder and the urethra. After the urine collected empties the renal pelvis, urine then goes down the ureter tube down to the bladder and out the urethra. However, if there is blockage in the ureter wall such as an obstruction and or kidney stone it may cause the urine to go back up into the kidney and causing the swelling of the kidney (Hydronephrosis). Other causes of blockage may …show more content…
• A blockage of the outflow of urine or reverse flow or urine already in the bladder (called reflux) can cause the renal pelvis to become enlarged.
• A blockage of the urethra can affect emptying of the bladder, causing the pressure in the bladder to be greater. This places extra pressure on the renal pelvis in both kidneys and on the ureters, which can dilate.
• Two ureters can drain a single kidney. In some cases, the connections can be abnormal and hydronephrosis or reflux can be a problem.
Symptoms Adults with hydronephrosis experience symptoms, in other cases, there may be no symptoms at all, newborns and infants with hydronephrosis usually show few to no symptoms. Some of those symptoms may include:
In adults:
• Increased urinary urgency
• Painful urination
• Urinary tract infection
• Fever
• Abdominal mass
• Flank
The kidneys are located in the posterior section of the retroperitoneal cavity and are small, dark red kidney-bean shaped organs in the lower part of the rib cage (Marieb, The Urinary System, 2015). They are undervalued organs considering how essential they are for the body’s ability to maintain homeostasis. The kidneys filter about 120-150 quarts of blood to produce about 1-2 quarts of urine each day (NIH, 2014). Blood initially enters the kidneys through the renal artery. It then flows into the segmental artery before moving into the interlobar artery. From the interlobar artery the filtrate enters the arcuate artery before branching into the cortical radiate artery, which feeds into the afferent arteriole, before passing into the glomerulus where it begins to filter out waste. The filtered waste is then collected by renal tubule. The tubules drain to collecting ducts and all of these components together makes up a small unit called a nephron. Each kidney has over a million nephrons (Marieb, Blood Supply/ Nephrons, 2015). They filter out wastes that run through different body systems via blood; the majority of that waste is nitrogenous wastes, toxins, excess fluids, electrolytes, and drugs. These waste products are eliminated as urine. While waste are removed vital enzymes, hormones, and water are returned
Many people never find out that they have had stones in their kidneys. Some stones are small enough to flow through the kidney without ever causing any pain. These are called "silent stones"(Ford-Martin & Odle, 2005) Kidney stones cause problems when they get in the way of the normal flow of urine. They can block the flow through the ureter that carries urine from the kidney to the bladder. “The kidney is not accustomed to experiencing any pressure. When pressure builds from backed-up urine, it causes hydronephrosis” (Ford-Martin & Odle, 2005). If the kidney is subjected to this pressure for a while, there may be damage to the fragile kidney structures. When the kidney stone is lodged further down the ureter, the backed-up urine may also cause the ureter to swell. Because the ureter is a musc...
Nephrolithiasis, more commonly known as kidney stones, is a common renal disease characterized by crystal depositions in the kidney as a result of urinary supersaturation. There are several types of stones, such as uric acid, cystine, and struvite stones, but calcium stones are the most common.
Kidney stones, a very common urinary tract disorder that is now really rampant in humans especially. Some causes of kidney stones are still being argued from whether it is due to what is consumed or having a history in the family. There are some common kidney stones which are phosphate, oxalate and calcium. This kidney stones may vary in sizes, in other words if the kidney stones in one that is small then there is a less tendency to notice. Although, most people would notice when they starting filling pains that feel like cramps on the back and the side in area around the kidney or lower abdomen. Due to the blockage of urine by the insoluble salt this causing more concentrated urine.
Urinary Tract Infection, also known as UTI, occurs in two common locations, the bladder and kidneys. The kidneys are important organs that aid in filtering out waste products from blood and maintaining water distribution throughout the body. The waste products are filtered out via bladder, which is the reason of the bladder being the second site for the infection. A normal human being has two kidneys, one on left and right side, a bean shaped organ, and is located at the back of the abdomen. “Each kidney is about 11.5 cm long, 5-7.5 cm broad, 5 cm thick, and weight about 150 grams” (HealthInfoNet, Paragraph 2). Furthermore, a bacterium named Escherichia coli lives in both the kidneys and the GI tract. E. coli is part of the human body and produces
The urinary tract consists of two kidneys, to ureters, urethra, and the urinary bladder. The urinary system works to remove waste from the body, maintain homeostasis of water, blood pressure, and regulate the body’s pH levels. The kidneys regulate several important internal conditions by excreting substances out into the body. After urine has been produced in the kidneys it is then transported to the urinary bladder via the ureters. The urinary bladder then holds the urine until the body is ready for excretion through the urethra.
As for the kidney’s, they consist of a renal cortex with arcuate vessels surrounds the renal medulla of the kidney. The renal papilla at the end of the renal medulla connects to the renal pelvis. Finally, a ureter descends form the kidney to the urinary bladder in both the mink and human.

Healthy kidneys clean the blood by filtering out extra water and wastes. They also make hormones that keep your bones strong and blood healthy. When both of your kidneys fail, your body holds fluid. Your blood pressure rises. Harmful wastes build up in your body. Your body doesn't make enough red blood cells. When this happens, you need treatment to replace the work of your failed kidneys.
can block the urinary tract. This blockage will probably cause a lot of pain. If
From the results of the numerous tests carried out according to the patient history of frothy urine with a significant oedema over a maximum period of 5 days, the patient was diagnosed with Nephrotic Syndrome. This is condition that occurs due to leakage in the kidney filtration part leading to a large amount of protein leaking from the blood into the urine. This is mainly due to fluid retention known as oedema which is as a result of low protein level in the blood. It occurs due to abnormal functioning or a part of the kidney is affected (glomeruli). This syndrome can be caused by numerous diseases coming together to cause or form one particular disease; these causes range from minimal change disease, membranous nephropathy, focal segmental glomerulosclerosis (FSGS) and other conditions, disorders of the glomeruli. The membranous nephropathy also known as the membranous nephritis or membranous glomerulonephritis, only causes diseases in adults and very uncommon in children. Leakage occurs from this due to the thickening of the membranous in the glomeruli which is the filter of the glomeruli. Focal segmental glomerulosclerosis is a causative due to the formation of small scars (sclerosis) on some of the kidney glomeruli. Another form of cause of nephrotic is minimal change which is due to lack of virtual change detected in the glomeruli when examined under the microscope. This causes the syndrome in 9 out of a total of 10 children under the age of 5 years.
A urinary tract infection is a very common infection that can happen to anybody. A urinary tract infection usually occurs when bacteria enters the urethra and multiples in the urinary system. The Urinary tract includes the kidneys, the thin tubes that carry urine from the kidneys to the bladder (ureters), and the main tube that carries the urine from the bladder (urethra). Women, men, and children are all immune to this infection. Women have the highest chances of getting it. In the Urinary tract, the main links of the ureters help get rid of any bacteria that tries to enter the urine, and the bladder helps prevent urine from backing up into the kidneys.
All play a role in removing waste from your body. Your kidneys filter waste from your blood and regulate the concentrations of many substances. Tubes called ureters carry urine from your kidneys to the bladder, where it’s store until it exits your body through the urethra.
The filtered blood leaves the kidney along the renal veins. The filtered waste products are excreted by the kidney as urine. A narrow tube called the ureter carries urine from the kidney to the bladder. From there the urine is excreted through a single tube, called the urethra. Kidney structure: If you cut a section through the kidney, three areas can be seen:
... restore the neutrality by producing more alkaline urine, leading to an increase in their workload (Epstein, 1997). This increased workload can lead to different dysfunctions or renal collapse.
