Cystoscopy and uretroscopy are examinations of the bladder and upper urinary tract respectively. Cystoscopy involves inserting a cystoscope through the urethra to examine the bladder. Similarly, uretroscopy uses a uretroscope to examine the ureters and kidneys. Reasons for these procedures include urinary issues like infections, blood in the urine, or abnormal growths. Patients may experience mild side effects after like burning during urination but risks are low. Both procedures provide important diagnostic information.
