Article Synopsis
- - This study compares two methods for performing percutaneous nephrolithotomy (PCNL), one using artificial hydronephrosis and the other treating directly via ultrasound, among 162 patients in an oblique supine position.
- - Results showed that the method without artificial hydronephrosis had a shorter procedure time and a significantly lower incidence of sepsis, though other outcomes like stone clearance rates were similar for both methods.
- - The conclusion suggests that experienced surgeons can safely perform PCNL without creating artificial hydronephrosis, which could streamline the process without compromising effectiveness or increasing complications.
Objectives: To evaluate the clinical efficacy of standard channel percutaneous nephroscope combined with flexible ureteroscope and traditional standard channel combined with microchannel percutaneous nephrolithotomy in the treatment of multiple renal calculi without hydronephrosis.
Methods: Eighty patients with multiple renal calculi without hydronephrosis treated in Shijiazhuang People's Hospital from January 2020 to October 2021 were randomly divided into two groups: the experimental group and the control group, with 40 cases in each group. Patients in the experimental group were treated with standard channel percutaneous nephroscope combined with flexible ureteroscopy lithotripsy, while those in the control group were treated with standard channel combined with microchannel percutaneous nephrolithotomy.
Background: Lymph node invasion (LNI) is a strong adverse prognostic factor in prostate cancer (PCa). The purpose of this study was to evaluate the role of Prostate Imaging Reporting and Data System version 2 (PI-RADSv2) scores for estimating the risk of LN metastasis. The study also aimed to investigate the additional value of PI-RADSv2 scores when used in combination with clinical nomograms for the prediction of LNI in patients with PCa.

Here we quantify the prognostic impact of these biomarkers and assess their consistency in RCC. Eligible studies were retrieved from the PubMed, Embase and Web of Science databases.
