摘要：
A percutaneous nephrolithotomy (PCNL) needle may include a cannula including a shaft and a cannula hub coupled to a proximal end of the cannula shaft. A depth guide may be disposed on an outer surface of the cannula shaft. A stylet may be disposable within the cannula lumen and may include a tapered point at a distal end of the stylet and a stylet hub coupled to a proximal end of the stylet that is configured to be releasably securable to the cannula hub. An adjustable depth stop may be releasably securable to the cannula shaft at a desired position relative to the depth guide, the adjustable depth guide capable of being manipulated between an adjustment configuration in which the adjustable depth guide is moveable relative to the cannula shaft and a secured configuration in which the adjustable depth guide is secured relative to the cannula shaft.
