Colectomy is a surgical procedure to remove all or part of the colon. When only part of the colon is removed, it is called a partial colectomy. The procedure is also known as a bowel resection. The colon is part of the body's digestive system.
The use of potassium-sparing diuretics is contraindicated in patients with anuria, acute or progressive renal insufficiency, or diabetic nephropathy. Potassium-sparing diuretics can cause hyperkalemia, which may result in life-threatening cardiac arrhythmias. Careful monitoring of serum potassium levels is necessary in all patients treated with potassium-sparing diuretics, especially during initiation of therapy, after dosage adjustment, and during illness that could alter renal function.
It is used to detect concentrations that are too high (hyperkalemia) or too low (hypokalemia). The most common cause of hyperkalemia is kidney disease, but many drugs can decrease potassium excretion from the body and result in this condition.he potassium test may be ordered at regular intervals to monitor effects of drugs that can cause the kidneys to lose potassium, particularly diuretics. Monitoring may also be done if someone has a condition or disease, such as acute or chronic kidney failure, that can be associated with abnormal potassium levels.
