This document outlines the indications, preparation, and procedure for urethroscopy and cystoscopy. Urethroscopy is used to inspect the urethra for strictures, diverticula, fistulas, lesions, and tumors. Cystoscopy allows for a systematic evaluation of the bladder, including the trigone, bladder neck, walls, and roof to identify tumors, trabeculations, lesions, diverticula, stones, and foreign bodies. Normal findings include a healthy bladder mucosa and ureteral orifices located within the trigonal rim that appear as slit-like indentations. Additional investigations like bladder washing may be indicated.
