It is a procedure in which a small scope (like a flexible telescope) is inserted into the bladder and ureter and it is used to diagnose and treat a variety of problems in the urinary tract. For ureteral stones, it allows the urologist to actually look into the ureter, find the stone and remove it.
The answer, though, is within reach: cold-brew coffee, a style that has enjoyed a recent resurgence for its natural sweetness, its lack of acidity and its simplicity. While a hot cup of coffee will have a stronger aroma and flavour, heat also brings out the bitter flavours of a bean.
Cold brewed coffee is also lower in acid, which may make it less prone to causing heartburn. Studies done by Toddy, maker of a cold brewing system, show that cold brewed coffee is 67% less acidic than hot brewed coffee. One reason for this may be that coffeeâs chlorogenic acid converts to quinic acid as it cools.
