Battle of the bots: a comparative analysis of ChatGPT and bing AI for kidney stone-related questions.

Objectives: To evaluate and compare the performance of ChatGPT™ (Open AI) and Bing AI™ (Microsoft) for responding to kidney stone treatment-related questions in accordance with the American Urological Association (AUA) guidelines and assess factors such as appropriateness, emphasis on consulting healthcare providers, references, and adherence to guidelines by each chatbot.

Methods: We developed 20 kidney stone evaluation and treatment-related questions based on the AUA Surgical Management of Stones guideline. Questions were asked to ChatGPT and Bing AI chatbots.

Impact of Renal Access Angle and Speed of Nephroscope Retrieval Movements on the Vortex Effect.

Objective: To analyze the influence of different renal access angles (AAs) and nephroscope retrieval speeds on the efficacy of the vortex effect (VE) in mini-percutaneous nephrolithotomy (mini-PCNL). This study aimed to understand the poorly understood physical components of the VE.

Materials And Methods: A Pexiglas™ (KUS®) model was built based on the dimensions of a 15/16 F mini-PCNL set (Karl Storz).

The Vortex Effect in Minimally Invasive Percutaneous Nephrolithotomy.

Objective: To describe the physical principles of the vortex effect to better understand its applicability in minimally invasive percutaneous nephrolithotomy (MIP) procedures.

Methods: Two acrylic phantom models were built based on the cross-sectional area (CSA) ratio of a MIP nephroscope and access sheaths (15/16F and 21/22F MIP-M, Karl Storz). The nephroscope phantom was 10 mm in diameter.

On the rocks: can urologists identify stone composition based on endoscopic images alone? A worldwide survey of urologists.

Purpose: As part of the management of nephrolithiasis, determination of chemical composition of stones is important. Our objective in this study is to assess urologists' accuracy in making visual, intraoperative determinations of stone composition.

Materials And Methods: We conducted a REDCap survey asking urologists to predict stone composition based on intraoperative images of 10 different pure-composition kidney stones of 7 different types: calcium oxalate monohydrate (COM), calcium oxalate dihydrate (COD), calcium phosphate (CP) apatite, CP brushite, uric acid (UA), struvite (ST) and cystine (CY).

Breakage Costs in Flexible Ureteroscopy: Digital vs. Fiberoptic Modalities.

Objective: To compare the maintenance costs of digital flexible ureteroscopes (DFU) versus fiberoptic flexible ureteroscopes (FFU) to understand the long-term financial impact associated with breakage in a flexible ureteroscopy (f-URS) program.

Methods: Data for breakage of FFU and DFU at an academic institution from 2019 to 2021 were obtained from our vendor (Karl Storz) and analyzed by month. Correlation test was used to evaluate significant differences in number of procedures, number of breakage events, breakage rates, and repair cost per month.

Image Distortion During Flexible Ureteroscopy: A Laboratory Model Comparing Super Pulsed Thulium Fiber Laser High-Power Ho:YAG Laser.

Digital ureteroscopes employ "chip-on-the-tip" technology that allows for significant improvement in image resolution. However, image distortion often occurs during laser lithotripsy owing to acoustic wave production. We sought to compare image distortion using different laser power settings and distances from the laser fiber tip to the scope for the Super Pulsed Thulium Fiber (SPTF) laser and high-power Holmium:YAG (Ho:YAG) laser.

Laparoscopic Boari flap for treatment of benign midureter stricture.

Introduction:: Laparoscopic ureteral reconstructive surgery represents a real challenge for most of the urologists as it requires advanced skills. Impacted stones (>2 months) and endoscopic procedures are known major risk factors for ureteral strictures. Boari flap is a good alternative, due to the high recurrence of kidney stone disease, as it preserves the feasibility of ureteroscopy.
