The purpose of this study is to compare two variations of the mini-PCNL procedure using either a vacuum-assisted sheath or standard sheath which are both used for the surgical treatment of kidney stones. Both procedure types are commonly used in the treatment of kidneys stones and they have been shown to be safe and effective in the treatment of stones similar in size and location to your own.
