What Is Open Gallbladder Removal. Open gallbladder removalâor cholecystectomy âis surgery that offers permanent relief to a patient suffering from gallstones and other problems associated with the gallbladder. The gallbladder is a small organ located near the liver. It stores bileâwhich is a special fluid produced in the liver.
GFR is a test that helps measure the level at which an individual's kidney is functioning. It is calculated on the basis of factors such as age, gender, race, and blood creatinine. Normal GFR values are between 90 to 120 ml/min. A GRF below 60 ml/min could mean that some kidney damage has occurred.
The higher the GFR, the better the kidney function. A GFR of 60-100 is generally considered normal (depending on your age and whether you are male or female). Most people do not have symptoms of decreased kidney function until the GFR is 20-30 or less, and some people donât feel sick until the GFR is as low as 10-15.
