Cystoscopy is an endoscopic examination of the bladder for diagnostic and surgical purposes. This diagnostic procedure is performed using a special set of medical instruments [https://eleps.ru/katalog/tsistoskopiya-i-transuretralnaya-rezektoskopiya-instrument/], which necessarily includes a viewing cystoscope—an optical instrument inserted into the bladder through the urethra. Cystoscopy is used to detect chronic urethral diseases, identify inflammatory processes, and detect neoplasms, tumors, injuries, and other bladder dysfunctions. The main indication for cystoscopy is blood in the urine; the procedure allows for the precise determination of the source of bleeding. Therapeutic manipulations using a cystoscope An operating cystoscope or catheterization cystoscope allows for numerous procedures and manipulations to be performed under anesthesia, aimed at restoring bladder function, removing papillomas, tumors, and foreign bodies, performing cystolithotripsy, ureteral catheterization, and many other surgeries.
