Eligibility
Inclusion criteria
Inclusion criteria: Only subjects who meet all of the following inclusion criteria are eligible for enrollment in this study: 1. Patients requiring retrograde ureteral stenting based on clinical indications. 2. Age = 18 years, regardless of gender. 3. Patients who voluntarily agree to participate in the study and provide signed informed consent.
Exclusion criteria
Exclusion criteria: Subjects who meet any of the following exclusion criteria will be excluded from this study: 1. Patients with severe urethral stricture that prevents dilation of the urethra and hinders the insertion of the bladder endoscope, making examination impossible. 2. Patients with a small bladder capacity, such as less than 50ml, where tuberculous bladder contraction is an absolute contraindication. 3. Patients with acute inflammation of the genitourinary system, such as acute cystitis, urethritis, prostatitis, or epididymitis. 4. Patients with uncorrected systemic hemorrhagic disorders. 5. Patients with severe hematuria that significantly interferes with the observation using the bladder endoscope. 6. Patients with other serious conditions who cannot tolerate bladder endoscopy surgery, as determined by the investigator, and are deemed unsuitable for participation in this study (excluding skeletal deformities or cases with difficult stone removal). 7. Patients with incomplete data or poor compliance. 8. Any medical or other conditions that the investigator deems may affect the clinical trial.
