Echogenic calculus of size 3mm noted in lower calyx. echogenic calculus of size 5mm noted in the mid ureter. taking drotin ds now. is surgery required?

Not necessarily: Surgery, usually endoscopic (using "scopes"), is only needed if stone is causing pain, too big to pass (usually >or= to 5 mm), or associated with blockage of ureter(blocking flow of urine) or associated urine infection. Most likely if stone is free in calyx it will pass on its own. If attached it may or may not cause symptoms. If no sxs may watch. Follow up with primary MD and/ or urologist.
