INTRODUCTION: The holmium laser has revolutionized the practice of minimally invasive endoscopy for kidney stones. Recently, a novel, rigid hand-piece for use in percutaneous nephrolithotomy (PCNL) that couples the holmium laser with suction has been developed. To date, there exists limited data regarding the usability and ergonomics of such treatment systems. We thus sought to compare surgeon-rated usability with three different suction laser hand-pieces in a porcine model. METHODS: We performed bilateral reverse PCNL on 4 female domestic farm pigs...

PURPOSE: We developed a polyethylene sack (the PercSac) that fits over the shaft of a rigid nephroscope and is deployed into the collecting system to capture a stone and contain fragments during PCNL. We previously reported results using the PercSac in a percutaneous cystolithopaxy model. Herein we compare the efficiency of stone fragmentation with and without the PercSac in an anatomically correct in vitro PCNL model. MATERIALS AND METHODS: The PCNL model consisted of a human collecting system model created on a 3-D printer...

Endoscopic treatment is currently the mainstay of management for urolithiasis. The high effectiveness of PCNL is well documented in the literature, as are its complications. Bleeding during PCNL is directly related to the size of the dilatation.(1) Several minimally invasive refinements in percutaneous surgery have been made to reduce access related complications and bleeding rates.(2) This was achieved mainly by reducing tract diameter, but the advantage over standard PCNL has yet to be proven.(3) The effectiveness of RIRS is decreasing with increasing stone burden...

OBJECTIVE: A wide selection of both anterograde and retrograde mini-invasive procedures exist for stones' treatment. The 2016 European Association of Urology (EAU) guidelines still don't univocally define a best option. Our purpose is to give an overview on some European Stone Centers' customs and to compare real life clinical practice with statements of opinion leaders and Guidelines. MATERIALS AND METHODS: In 2015 we performed a survey in 3 step about the spread of retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) techniques among EAU Section of Urolithiasis (EULIS) members...

Background: Percutaneous nephrostolithotomy is an important approach for removing kidney stones. Puncturing and dilatation are two mandatory steps in percutaneous nephrolithotomy (PCNL). Uncommonly, during dilatation, the dilators can cause direct injury to the main renal vein or to their tributaries. Case Presentation: A 75-year-old female underwent PCNL for partial staghorn stone in the left kidney. During puncturing and dilatation, renal vein tributary was injured, and the nephroscope entered the renal vein and inferior vena cava, which was clearly recognized...

The medical and surgical complications of percutaneous nephrolithotomy (PCNL) are well-known, including deep venous thrombosis. Ovarian vein thrombosis (OVT) is a rare, but potentially serious type of venous thrombosis that has not previously been reported as a complication of PCNL or ureteral stent placement. We report a case of OVT associated with ureteral stenting following a tubeless PCNL. This complication was successfully managed conservatively without any short- or long-term sequelae.
