A case is reported of a 58 year old patient with a diagnosis: double giant ureterocele, secondary multiple calculi of the right ureterocele, calculus of the inferior calyx of the right kidney, calculus of the terminal part of the left ureter, double ureterohydronephrosis, chronic pyelonephritis, multiple calcifying myoma of the uterus. A combined single-stage operation (panhysterectomy, deletion of multiple calculi of the right ureterocele, deletion of the calculus of the left ureterocele, crosscut right ureterectomy with excision of ureterocele, right ureterocystoneostomy by Leadbetter-Politano, installation of the double J-stent into the right kidney, crosscut and longitudinal left ureterectomy with excision of ureterocele, left ureterocystoneostomy by Leadbetter-Politano, installation of intubating drainage into the left ureter, cystostomy) followed by extracorporeal shock-wave lithotripsy were performed in this adult patient with combined pathology of the urinary system.

Dangerous rock masses in mountainous areas seriously threaten the construction and operation of engineering with potential disaster hazards, especially the unpredictability and sudden occurrence of rockfall, which poses a huge challenge. This paper presents a systematic risk assessment and disposal of high and steep giant dangerous rock masses, which can pose a serious threat to railway operation. Using comprehensive methods such as on-site investigation, limit equilibrium method, and simulation analysis of rockfall trajectory, the possibility and potential harm of collapse and rockfall of giant dangerous rock masses are analyzed and corresponding remediation measures are proposed.

Introduction: Transurethral resection of the prostate (TURP) is the gold standard surgical treatment to lower urinary tract symptoms and benign prostatic obstruction (LUTS/BPO). Although it has been proven to have substantial efficacy in improving functional outcomes, it has shown a high incidence of complications, including transurethral resection syndrome, massive bleeding, urinary incontinence and sexual dysfunction. High-frequency irreversible electroporation (H-FIRE) is a novel non-thermal ablation technique that delivers pulsed high-voltage but low-energy electric current to the cell membrane, thereby leading to cell death.

Most giant viruses including Mimiviridae family build large viral factories within the host cytoplasms. These giant viruses are presumed to possess specific genes that enable the rapid and massive replication of their large double-stranded DNA genomes within viral factories. It has been revealed that a functionally uncharacterized protein, MutS7, is expressed during the operational phase of the viral factory.

Percutaneous renal puncture drainage is needed in patients with perirenal hematoma (PRH, renal around hematoma) with poor conservative treatment. Early and thorough removal of hematoma is closely related to the recovery of patients, but percutaneous renal drainage is not effective in some patients. The clinical data of 5 patients with PRH treated in the first affiliated Hospital of Chongqing Medical University from June 2020 to June 2024 were analyzed retrospectively.
