What is the connection between renal function and hypotension?

Hypotn decreares fxn: Low blood presure to the kidneys causes the kidneys to malfuntion. The kidneys need a large blood volume with an adequate pressure to perfuse and function properly. When the BP is low the kidneys hold on to fluids and urine out put drops. The BUN and cr are elevated indicating a back up of waste and when it goes on longperiod of time its called atn or acute tubular necrosis. If no relief dialysis. ...Read more

Hypotension (Definition)

Hypotension is defined as "low blood pressure". Blood pressure is measured as two numbers and expressed as systolic blood pressure (sbp) / diastolic blood pressure (dbp). The sbp is the pressure that is generated when the heart squeezes. Dbp occurs when the heart relaxes. 120/70 is considered normal in adults. Less than 100/60 (of either number) can ...Read more

I'm wondering what effect could the low blood pressure have on renal function?

Blood pressure: Low pressure can decrease the filtration through the kidney resulting in a decreased total renal function. ...Read more

Why does renal or aortic stenosis usually cause hypotension?

Why does renal or aortic stenosis usually cause hypotension?

They don't: Renal artery stenosis usually causes hypertension. In fact it can be difficult to control. Aortic stenosis doesn't cause hypotension until very late which can be dangerous if the heart has thickened. In my experience most of my patients with aortic stenosis have either normal or high blood pressure. ...Read more

Pre-renal acute renal failure may occur without systemic hypotension in patients taking nsaid or acei , why ? I just do not get it ?

Pre-renal acute renal failure may occur without systemic hypotension in patients taking nsaid or acei  , why ? I just do not get it ?

Effect blood flow: Nsaids interfere with prostaglandin production in the kidney , some of which may cause blood vessels to dilate. Blocking the prostaglandin production causes the vessels to constrict and decreases blood flow to the kidney. Acei inhibit angiotensin ii production this allows the efferent arteriole to dilate, lowering the hydrostatic pressure in the glomerulous and decreasing kidney function. ...Read more

What is good renal function in your later years?

What is good renal function in your later years?

Renal function: The better the renal function, the better the overall prognosis. As people age, they lose some renal function (change in muscle mass, senescence of the kidney). Each person is individual as to what function they need to survive and function well. Usually a creatinine clearance above 30% is enough to keep one off dialysis and functioning well, but it depends on the patient. ...Read more

What is significance of small bilateral renal cortical cysts if renal function tests are normal?

What is significance of small bilateral renal cortical cysts if renal function tests are normal?

Not much, but: Need a follow up ultrasound in a few years to see if increasing suggestive of polycystic kidney disease (pkd). If this is the case there is a chance to lose kidney function over long years. It is not a cancer. But increasing cysts number and size can overtake kidneys. Chances are, none of that will happen to you. But, better safe than sorry. Pkd is a benign and slow condition but may cause failure. ...Read more

90 year old with E. coli and renal function getting worse, now 3.5. What can be done for her to get better?

90 year old with E. coli and renal function getting worse, now 3.5. What can be done for her to get better?

Treat infection: Gentle hydration, adjust meds for kidney function and age, control symptoms, avoid unnecessary hospital stays, have realistic expectations. Ask about palliative care and have advanced directives ready. ...Read more

Does colchecine affects renal function?

Does colchecine affects renal function?

Yes it can: It's a good idea to have a baseline renal function test (bun/creatinine) when one is on colchicine. ...Read more
