It depends on the channel/transporter being blocked. For example, it's well established that a type of diuretic called a loop diuretic (eg, furosemide) causes hypercalciuria, a fancy term for excess calcium in the urine. Loop diuretics work by blocking a sodium-potassium-chloride transporter in the kidney, and indirectly result in decreased calcium reabsorption from the urine. Because most kidney stones are made of calcium, the excess urinary calcium caused by loop diuretics can predispose people to kidney stones.
By contrast, thiazide diuretics (eg, hydrochlorothiazide) commonly used to treat high blood pressure often cause hypocalciuria, which is decreased urinary calcium. Thiazides work by blocking a sodium-chloride transporter in the kidney, indirectly causing increased calcium reabsorption so less ends up in the urine. So thiazide is a reasonable medication to use for treating high blood pressure in patients prone to kidney stones.
Thiazide and loop diuretics aren't technically "channel blockers", but I'm assuming you're using the term loosely. Perhaps I'm wrong though.
kidney fail
no
No it does not.
KIDNEY'S ARE ALREADY SHAPED LIKE SHOES!!!!!!! DERR
That is when you get dumb like your mom.
kidney
The renal system.
no you don not dye ,its chemical impact can disturbed your body and also effect on kidney
Heart opening
A PET scan can have a negative effect on a kidney. If dye is used, this can cause a problem for some people. It is also good for detecting illness, though.
Generally speaking, little or no effect on kidney function. However, kidney function may have an effect on the drugs. Most antibiotics are excreted via the kidneys, and reduced kidney function can cause a buildup in the body exceeding normal dosage levels.
The condition known as polycystic kidney disease is inherited and the cysts slowly reduce kidney function and leads to kidney failure. the condition can also effect the liver and pancreas.
