This study explores how artificial intelligence technologies can enhance the regulatory capacity for legal risks in internet healthcare based on a machine learning (ML) analytical framework and utilizes data from the health insurance portability and accountability act (HIPAA) database. The research methods include data collection and processing, construction and optimization of ML models, and the application of a risk assessment framework. Firstly, the data are sourced from the HIPAA database, encompassing various data types, such as medical records, patient personal information, and treatment costs.

Purpose: To investigate the effects of flow rate on pressure and nephron injury during flexible ureteroscopy with intelligent renal pelvic pressure (RPP) control in an in vivo pig model.

Methods: Twelve kidneys from six female pigs were randomly divided into six groups. Pressure-controlled (PC) and non-pressure-controlled (NPC) groups were continuously perfused at a flow rate of 50 mL/min (group A), 100 mL/min (group B), and 150 mL/min (group C) for 30 min.

We performed a comparative analysis of intelligent pressure-controlled ureteroscopic lithotripsy (IRIRS) and intelligent pressure-controlled microchannel percutaneous nephrolithotomy (IMPCNL) to treat 2-3 cm renal calculi. Patients (n = 140) with 2-3 cm renal calculi were randomly divided into the IRIRS and IMPCNL groups (n = 70/group). Surgical time, length of hospital stays, stone clearance rate, decrease in hemoglobin level, postoperative pain score, and incidence of complications were compared between groups.

Background: To explore the feasibility and safety of aflexible ureteroscopy with intelligent control of renal pelvic pressure(FUS-ICP) without a post-operative indwelling urinary catheter .

Methods: In this retrospective study, we assessed patients with upper urinary tract stones who were treated with FUS-ICP at the Ganzhou People's Hospital from February 2022 to December 2023. Patients were divided into the non-urinary catheter (non-UC) and urinary catheter (UC) groups according to whether an indwelling catheter was used after surgery.

Article Synopsis
  • - The study explored how effectively renal pelvic pressure (RPP) is managed during flexible ureteroscopy using a ureteral access sheath (UAS), which combines pressure measurement and suction features.
  • - Eleven patients with kidney stones participated, and during the procedure, RPP was consistently monitored and maintained at safe levels across different areas of the kidney without significant pressure differences from the control measurements.
  • - The findings suggest that the UAS technology is accurate and reliable for controlling renal pelvic pressure within the desired range, making it a promising tool for kidney stone treatments.

Background: Retrograde intrarenal surgery (RIRS) is being increasingly used to treat 2-4 cm renal stones, which can be attributed to advances in flexible ureteroscopes and ureteral access sheaths (UASs). Despite the improvement and application of flexible vacuum-assisted (FV) and intelligent pressure-controlled (IPC) UASs, no studies have compared their therapeutic efficacy and safety. Therefore, this study aimed to compare the therapeutic efficacy and safety of IPC-UAS and FV-UAS in RIRS 2-4 cm renal stones.

Introduction: Urinary calculi are frequently encountered in urology. Traditionally, the lack of a perfect water injection and drainage system means the observation field is affected during ureteroscopy. Here, we explored the effect and clinical value of a new integrated suctioning semi-rigid ureteroscopic lithotripsy (URSL) for treating ureteral calculi.
