Urine (Definition)

Urine is the product of the kidneys, which is produced to eliminate the waste products of metabolism, manage body fluid balance, &maintain acid-base balance. The blood is first filtered by the kidneys, and the composition of the resulting fluid is then altered depending on the body's needs. It is composed of mostly water, and breakdown products from blood cells impart ...Read more

What happens to plasma and urine osmolarity with a lung tumor that secretes vasopressin (adh)?

What happens to plasma and urine osmolarity with a lung tumor that secretes vasopressin (adh)?

V plasma & ^ Urine: Vasopressin/adh increases the amount of water reabsorbed by the kidneys and decreases the amount of water excreted into the urine. With more water in the bloodstream, the concentration of everything else decreases (so osmolality goes down), while the concentration of everything in the urine goes up (as dose the urine osmolality). ...Read more

?fistula: Usually, air in the urine, either as sputtering or foam and bubbles, indicates a connection between the bladder and an air containing viscus, like the colon or small bowel - a fistula. This would also lead to chronic urinary tract infection. See your doctor for a thorough history, exam, and urinalysis. Good luck. ...Read more

What changes in blood volume, blood potassium, urine volume and urine sodium would turn on the raa system?

What changes in blood volume, blood potassium, urine volume and urine sodium would turn on the raa system?

RAAS turn ons: The renin angiotensin aldosterone system is designed to maintain blood volume. It is turned on when there are actual fluid deficits, such as vomiting or dehydration, or deficits perceived by the kidney as those patients with congestive heart failure. As a result of increased activity of the RAAS, urine volume and sodium losses by the kidney decreases. High potassium is possible, as well. ...Read more

Any feedback on high urinary output without excessive intake, electrolytes off in blood and 24hr urine. Also, High protein in urine, low nitrogen ua?

Any feedback on high urinary output without excessive intake, electrolytes off in blood and 24hr urine. Also, High protein in urine, low  nitrogen ua?

Nephrologist: A kidney specialist is best qualified to evaluate and advise you. High urinary output out of proportion to fluid intake could be due to a pituitary gland problem,diabetes mellitus, or primary kidney disease. High protein in the urine suggests kidney damage. The nephrologist will order the appropriate tests and diagnose your problem. ...Read more

Do blood and urine mix in the kidneys?

Do blood and urine mix in the kidneys?

Not usually: Urine is made from water and waste products the blood stream delivers to the kidneys. In effect, the kidneys are giant filters, but the blood vessels pass through microscopic structures which do the filtering. The blood vessels and urine vessels do not mix; there is a thin layer of cells which separate the two, but allow the transfer of waste chemicals in the blood into the urine. ...Read more

Egfr is 57... Normal bun and creatinine. Frequent urination and thirst. Could it be diabetes insipidus? My urine is always clear. Sg is 1.005

Egfr is 57... Normal bun and creatinine. Frequent urination and thirst. Could it be diabetes insipidus? My urine is always clear. Sg is 1.005

Workup plan: I'd ignore the estimated gfr; it is subscientific especially if BUN and creatinine are within normal limits. Trusting the urinalysis and urinary sediment are okay. Your next step will be a test to see if you can concentrate your urine; your physician will supervise. If you can't, you'll be given ADH (vasopressin) to see if that fixes things; this distinguishes pituitary from renal diabetes insipidus. ...Read more

Urine production and urination are controlled by which hormones?

Urine production and urination are controlled by which hormones?

Antidiuretic hormone: ADH (vasopressin) acts on kidney tubules to control amount of water to be reabsorbed after initial blood filtration by kidney glomeruli (mini-filters). ADH (vasopressin) is produced by pituitary gland with more produced at night to reduce urine output & less by day. Urination controlled by nervous system & not by hormones. ...Read more

What is the relationship between ADH (vasopressin) and aqp2 in urine production?

What is the relationship between ADH (vasopressin) and aqp2 in urine production?

Signal/response.: Adh, or vasopressin, is a hormone released by the posterior pituitary gland when the body wishes to conserve water. Aquaporin 2 (aqp2) channels in the kidney are activated by adh, which reabsorb water back into the bloodstream, concentrating and decreasing the volume of urine. Mutations in aqp2 can lead to diabetes insipidus, where large volumes of urine are released. ...Read more

Urinary tract stones, usually arising from the kidneys will sometimes mimick a uti. It's best to see your physician to have a urine culture done. Post coital voiding will help reduce the frequency of utis. ...Read more
