The safety and efficacy of Sotn ureteroscopy for renal and upper ureteral calculi: a prospective multicenter randomized controlled trial.

Background: Sotn ureteroscopy is a new lithotripsy procedure developed on the basis of ureteroscopy and includes a rigid ureteral access sheath, standard mirror, lithotripsy mirror, and Sotn perfusion aspirator. Thus, we performed a prospective multicenter randomized controlled trial comparing the safety and efficacy of Sotn ureteroscopy in the treatment of renal and upper ureteral calculi.

Methods: In this study, 224 patients with renal and upper ureteral calculi were randomly divided equally into study and control groups from March 2018 to March 2022.

Prostate Volume is A Predictor of Gleason Score Upgrading after Radical Prostatectomy in Low-Risk Prostate Cancer: A Systematic Review and Meta-analysis.

Purpose: The prediction of Gleason score (GS) upgrading in patients diagnosed with low-risk prostate cancer is particularly important when opting for active surveillance (AS). Thus, we aimed to explore the association between prostate volume and GS upgrading after radical prostatectomy in low-risk prostate cancer through a meta-analysis.

Methods: Multiple databases (Web of Science, MEDLINE, Embase, Scopus, and the Cochrane Library) were searched for eligible studies regarding this issue and reporting sufficient data up to May 2023.

Case Report: Giant paratesticular liposarcoma was resected and refused radical orchiectomy.

Paratesticular liposarcoma (PLS) causes scrotal mass changes, rarely in the urinary system. Before surgery, PLS causes scrotal mass changes that are difficult to distinguish from other causes. There has been a report of a giant paratestis liposarcoma resection and refusal to undergo orchiectomy.

Primary squamous cell carcinoma with sarcomatoid differentiation of the kidney associated with ureteral stone obstruction: A case report.

Background: Primary squamous cell carcinoma (SCC) with sarcomatoid differentiation of the kidney was rarely reported. This disease is usually related to renal stones, and due to a lack of symptoms and radiological features, patients usually attend the hospital with late stage disease.

Case Summary: A 54-years-old female presented with left flank pain and an abdominal mass for 6 mo.

Immunoglobulin G4-related kidney disease involving the renal pelvis and perirenal fat: A case report.

Background: Immunoglobulin (Ig) G4-related disease (IgG4-RD) is an autoimmune disease associated with chronic and progressive inflammation and fibrosis. It is difficult to differentiate IgG4-RD involving the kidney from infectious diseases and malignancy on imaging.

Case Summary: We report the case of a 51-year-old Chinese man whose abdominal computed tomography scan showed diffuse bilateral enlargement of the kidneys and perirenal fat, thickening of the renal pelvic walls, and hydronephrosis of the right kidney.

Diagnosis accuracy of PCA3 level in patients with prostate cancer: a systematic review with meta-analysis.

Objective: This study aims to design a novel semirigid ureterorenoscope with irrigation and vacuum suction system and a modified ureteral access sheath (UAS) named Sotn ureterorenoscope® (Sotn=ShuoTong Medical Company) to overcome the deficiencies of the current procedure and to improve the efficiency and safety of using Sotn ureterorenoscope® for treatment of upper urinary calculi.

Materials And Methods: Fifty-eight patients, comprising 31 males and 27 females, were evaluated. The medical records of 58 patients with upper urinary calculi treated with Sotn ureterorenoscope® from March 2015 to June 2017 were retrospectively reviewed at the Second Affiliate Hospital of Guangzhou University of Chinese Medicine in China.
