Urine moves from the kidney to the bladder through the ureter. A series of compression waves facilitates this transport. Due to the highly concentrated mineral deposits in urine, stones are formed in the kidney and travel down through the urinary tract. While passing, a larger stone can get stuck and cause severe damage to ureter wall. Also, stones in the ureter obstructing the urine flow can cause pain and backflow of urine which in turn might require surgical intervention. The current study develops a 2D axisymmetric numerical model in order to gain an understanding of the ureter obstruction and its effects on the flow, which are critical in assessing the different treatment options...

Computed tomography (CT) is the method of choice for diagnosing ureteral stones - kidney stones that obstruct the ureter. The purpose of this study is to develop a computer aided detection (CAD) algorithm for identifying a ureteral stone in thin slice CT volumes. The challenge in CAD for urinary stones lies in the similarity in shape and intensity of stones with non-stone structures and how to efficiently deal with large high-resolution CT volumes. We address these challenges by using a Convolutional Neural Network (CNN) that works directly on the high resolution CT volumes...

INTRODUCTION: The Lithocatch (TM) basket is a immobilization device commercialized by Boston Scientific. It allows to collect multiple stone fragments from the ureter. The ability of the basket to capture a large number of stone fragments, is however responsible for a problem connected to its usage: the entrapment of the basket inside the ureter. In this video we explain how to use it and how to solve this problem. MATERIAL AND METHODS: After positioning the Lithocatch (TM) over the fragments, the basket is opened and it is rotated through a special handle to collect stones...

INTRODUCTION: Nephrolithiasis is one of the most common diseases in urology. According to the EAU Guidelines, a percutaneous nephrolitholapaxy (PNL) is recommended when treating a kidney stone >2 cm. Nowadays PNL is performed even for smaller stones (<1 cm) using miniaturized instruments. The most challenging part of any PNL is the puncture of the planned site. PNL-novice surgeons need to practice this step in a safe environment with an ideal training model. We developed and evaluated a new, easy to produce, in-vitro model for the training of the freehand puncture of the kidney...
