What is Isosthenuria and what are its causes?

Causes of Abnormally Low Levels Isosthenuria (USG 1.008–1.014) occurs with renal disease ( >75% nonfunctioning tubules or chronic renal failure), administration of diuretics (furosemide) and hypercalcemia. Why do I get Isosthenuria?
Isosthenuria may be seen in disease states as chronic and acute kidney injury in which the kidneys lack the ability to concentrate or dilute the urine and so the initial filtrate of the blood remains unchanged despite the need to conserve or excrete water based on the body’s hydration status.

What does a urine specific gravity of 1.020 mean?

Ideally, urine specific gravity results will fall between 1.002 and 1.030 if your kidneys are functioning normally. Specific gravity results above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated you may be. What does Isosthenuria mean in medical terms?
Medical Definition of isosthenuria : a condition in which the kidneys produce urine with the specific gravity of protein-free blood plasma.

What does Hyposthenuria mean?

Definition. An abnormally low urinary specific gravity, i.e., reduced concentration of solutes in the urine. [ from HPO] How is Isosthenuria pronounced?

Frequently Asked Questions(FAQ)

What causes low urine osmolality?

Several conditions may cause low urine osmolality, including: excessive fluid intake, or over-hydration. kidney failure. renal tubular necrosis.

What causes renal osteodystrophy?

Types of Osteodystrophy Osteodystrophy is most often the result of chronic kidney disease (CKD), a condition in which the gradual loss of renal (kidney) function causes wastes to accumulate in the body as the kidneys start to fail.

Is urine specific gravity 1.030 normal?

The normal range for urine specific gravity is 1.005 to 1.030. Normal value ranges may vary slightly among different laboratories.

What does Urobilinogen 0.2 mean?

Normal Levels Urobilinogen is normally found in trace amounts in the urine (0.2 – 1.0 mg/dL) [7]. Urobilinogen levels < 0.2 mg/dL are considered low. Urobilinogen levels > 1.0 mg/dL are considered high [8]. However, these values vary from lab to lab.

What is the normal pH of urine?

What does specific gravity of 1.005 in urine mean?

Specific gravity. Normal: 1.005–1.030 footnote1. Abnormal: A very high specific gravity means very concentrated urine, which may be caused by not drinking enough fluid, loss of too much fluid (excessive vomiting, sweating, or diarrhea), or substances (such as sugar or protein) in the urine.

What is Leu in urine test?

Leukocyte esterase is a screening test used to detect a substance that suggests there are white blood cells in the urine. This may mean you have a urinary tract infection. If this test is positive, the urine should be examined under a microscope for white blood cells and other signs that point to an infection.

What is concentrated urine?

More concentrated urine means that there are more solutes and less water in the sample. Solutes are dissolved particles, such as sugars, salts, and proteins. Normal values may vary based on the laboratory used.

What is a uremic patient?

Uremia is a dangerous condition that occurs when waste products associated with decreased kidney function build up in your blood. Uremia means “urine in the blood” and refers to the effects of the waste product accumulation. It affects the entire body.

What is bland urine?

What causes papillary necrosis?

Common Causes Renal papillary necrosis has a wide range of causes, including diabetes, analgesic abuse or overuse, sickle cell disease, pyelonephritis, renal vein thrombosis, tuberculosis, and obstructive uropathy.

How is RTA diagnosed?

Diagnosis of RTA Type 4 renal tubular acidosis is usually suspected when high potassium levels accompany high acid levels and low bicarbonate levels in the blood. Tests on urine samples and other tests help to determine the type of renal tubular acidosis.

What does microscopic hematuria mean?

Microscopic hematuria means that the blood can only be seen with a microscope. Gross hematuria means the urine appears red or the color of tea or cola to the naked eye.

What is dog Polydipsia?

Polyuria and polydipsia (PU/PD) are frequent presenting complaints in small animal practice. Polyuria is defined as a daily urine output of greater than 50 ml/kg per day, while polydipsia is defined as a fluid intake of more than 100 ml/kg/day.

What is osteodystrophy?

Osteodystrophy: A bone disorder that adversely affects bone growth. See also renal osteodystrophy.

Is Fanconi syndrome fatal?

Symptoms and Signs of Fanconi Syndrome In hereditary Fanconi syndrome, the chief clinical features—proximal tubular acidosis, hypophosphatemic rickets, hypokalemia, polyuria, and polydipsia—usually appear in infancy. develops, leading to progressive renal failure that may be fatal before adolescence.

What is the definition of haematuria?

Hematuria is the presence of blood in a person’s urine.

What does low urine osmolarity mean?

Lower than normal measurements may indicate: Damage to kidney tubule cells (renal tubular necrosis) Diabetes insipidus. Drinking too much fluid. Kidney failure.

What is the normal range for urine osmolality?

An individual with a normal diet and normal fluid intake has a urine osmolality of approximately 500-850 mOsm/kg water. After age 20 years, the upper level of the reference range declines by about 5 mOsm/kg/year.

What is the normal range for urine sodium?

For adults, normal urine sodium values are generally 20 mEq/L in a random urine sample and 40 to 220 mEq per day.

What are the four main types of renal osteodystrophy?

Renal osteodystrophy is a term used to describe the skeletal complications of ESRD caused by a complex amalgam of various pathologic processes (see Chapter 205). The four principal types are osteitis fibrosa (formally known as osteitis fibrosa cystica), osteomalacia, adynamic bone disease, and mixed disease.

How is renal osteodystrophy diagnosed?

How is renal osteodystrophy diagnosed? To diagnose renal osteodystrophy, your doctor may take a sample of your blood to measure levels of calcium, phosphorus, PTH, and calcitriol. The doctor may perform a bone biopsy to see how dense your bones are.
