A Novel Device To Remove Kidney Stone Fragments From The Ureter, Madeline Feinberg, Christina Pavlovsky, John Kasel
Honors Theses
Every year kidney stones affect 654,000 Americans and 25% of these cases require a ureteroscopy which is performed on patients with kidney stones greater than 4 mm in the ureter. A holmium laser is used to rupture the kidney stone resulting in fragmentation of the stone. If not removed, these residual fragments can cause pain and may require a secondary procedure to remove them. The most common method for removing stone fragments is inserting a basket device through a port on the ureteroscope, encapsulating individual stone fragments, and manually removing the device. This device requires multiple insertions to remove the …

Access Recirculation (AR) severely decreases the efficiency of dialysis while having the potential to lead to a variety of complications (Fig. 3). If recirculation occurs during treatment, the patient may be at risk of developing stenosis (narrowing of blood vessels), leading to thrombosis (the local coagulation/clotting of blood) [4]. The most influential cause of recirculation results from the misplacement of the arterial and venous needles that will significantly harm the patient, wasting both money and resources. It is clear that the medical community has focused their energy on developing a proactive approach to monitoring AR, instead of preventing it. Creating …
