The procedure is usually performed during ureteroscopy (endoscopic examination of the ureter) when the doctor detects a suspicious area, stricture, or neoplasm. Code PG037 corresponds to the pathological analysis of material taken from a single ureter.<\/p>\n<p data-path-to-node=\"2\"><b data-path-to-node=\"2\" data-index-in-node=\"0\">Research objective:<\/b> The main task is morphological verification of the pathological process.

In benign processes or tumors of low aggressiveness, organ-preserving treatment (endoscopic removal) is possible.
