The American Heart Association describes heart failure as a condition that occurs when this important organ, essentially a pump, cannot effectively push blood out through the arteries and circulatory system to the body’s other organs and tissues. Congestive heart failure, a worsening of this general condition, means blood flow from the heart through the arteries has slowed while blood returning to the heart through the veins has begun to back up and combined they cause congestion — a blood traffic jam — in ta the body’s tissues. The result is edema, or swelling, usually in the legs and ankles, though edema can happen anywhere in the body. Heart failure also impairs the kidneys’ ability to dispose of water and sodium, causing even more swelling. When pulmonary edema happens, fluid collects in the lungs and interferes with breathing. Conditions that can lead to heart failure include high blood pressure, diabetes, obesity and coronary artery disease — when plaque builds up in the walls of arteries causing them to narrow and increasing the difficulty of pumping blood. Heart failure, then, is a medical condition that needs to be treated to prevent a life-threatening heart attack.

For example, up to 98% of small stones less than 5 mm 0.2 in diameter may pass spontaneously through urination within four weeks of the onset of symptoms, 3 but for larger stones 5 to 10 mm 0.2 to 0.4 in diameter, the rate of spontaneous passage decreases to less than 53%. 80 Initial stone location also influences the likelihood of spontaneous stone passage. Urea is usually excreted as a waste product from the kidneys. A recessed area on the concave border is the renal hilum, where the renal artery enters the kidney and the renal vein and ureter leave. Infection stones can grow rapidly, forming large calyceal stag horn antler shaped calculi requiring invasive surgery such as percutaneous nephrolithotomy for definitive treatment. 58 Struvite stones triple phosphate/magnesium ammonium dig this phosphate have a ‘coffin lid’ morphology by microscopy. 57 About 5–10% of all stones are formed from uric acid. 17 People with certain metabolic Nice sentiments abnormalities, including obesity, 16 may produce uric acid stones.
