Abstract:The authors report on results of a randomized prospective trial in comparable groups of patients with intrarenal stones treated by flexible ureteroscopy and laser lithotripsy (1). Patients were randomized to either general or regional epidural anesthesia with the primary outcome measures being surgeon comfort and other standard measureable results of fURS treatment. After exclusions or intraoperative conversion to general anesthesia or PCNL, 45 patients in the RA group were compared to 61 in the GA group. They… Show more
“…For the B-ultrasound image model, the fidelity constraint item is improved, and the uniqueness of the model solution in the space. The gradient method used in this paper is slower to ensure that the model is a convex model [ 15 ].…”

At present, percutaneous nephrolithotomy has become an option for hospitals increasingly to treat calculus. However, due to the certain risk of percutaneous nephrolithotomy, it may lead to postoperative complications. Analyzing the preoperative factors of septic shock after percutaneous nephrolithotomy can provide guidance for reducing the incidence of septic shock after PCNL. This article establishes a logistic regression model based on preoperative factors, uses statistical methods, and uses the professional statistical software SPSS to create a database and analyze the data. The method of classification data analysis was used to determine various influencing factors including patient factors, stone factor, and preoperative factors and combined B-ultrasound guidance and percutaneous nephrolithotomy to reduce the risk of surgery. The experimental results found that the percutaneous nephroscope laser lithotripsy guided by the smart Internet of Things can effectively perform lithotripsy; in this paper, the preoperative data of different complications are obtained, and the risk of surgery is closely related to the operation time. The operation time exceeds 90 minutes and causes the risk of severe bleeding after PCNL. It is twice the operation time of less than 90 minutes and 5 times the operation time of less than 60 minutes.
