Uroscopy generally refers to urethroscopy, which can observe the overall condition of the urethra, bladder and ureter to see whether there is inflammation, foreign bodies, stones, etc., and timely symptomatic treatment when corresponding pathological changes occur. Urethroscopy is a common diagnostic and therapeutic modality in urology. Through the endoscope into the urethra, the whole urethra can be observed to find out whether there are any foreign bodies, strictures, etc. The bladder and ureter can also be observed through the endoscope into the ureter. The structures such as the bladder and ureter can be examined for inflammation and stones. If bladder stones, urethral stones, ureteral stones, etc. are found through urography, they can also be treated by laser access to the bladder or urethra with the appropriate equipment. Uroscopy can be used to understand the overall condition of the urinary tract, and to go to the hospital in time when there are uncomfortable symptoms.
