X-ray endoscopic removal of urothelial cancers of the upper urinary tract

The aim of this work is to evaluate the results of endoscopic treatment of patients with urothelial cancers of the upper urinary tract (URCoUUT). Materials and methods: 99 patients with a tumor of the upper urinary tract (UUT) were examined, 24 of them in the Urology Clinic of the First Moscow State Medical University named after I.M.Sechenov performed endoscopic treatment (in 21 cases, retrograde removal of pelvic and ureter malignant neoplasms was performed, in 1 - percutaneous removal of papillary cancer of the pelvis of a single kidney, per 1 percutaneous removal of papillary cancer of the pelvis of a single functioning kidney and in 1 - percutaneous removal of papillary cancer of the calyx lower half of the l-shaped kidney). Results. In all cases, during a follow-up examination at different times after the operation, there was no evidence of a relapse, the passage of urine along the upper urinary tract was not disturbed. The conclusion. due to its effectiveness, safety and minimal invasiveness, URS is an alternative for the treatment of patients with urothelial carcinoma of low-grade. Percutaneous methods for the removal of URCoUUT can be used in patients with low-grade calyceal tumors, which are impossible or very difficult to achieve, even with flexible URS, with relatively large pelvic lesions or with technical impossibility of performing the intervention retrograde.
