[Diagnosis and surgical treatment of tumors of the upper urinary tract].

Abstract

The author believes that in diagnosis of tumors of the upper urinary tracts more information can be obtained at ureteropyeloscopy with retrograde contrasting of the urinary tracts and, if necessary, biopsy of abnormal urothelium regions. 19 patients with pelvic and 4 patients with ureteral tumor were operated on. 2(8.7%) patients with tumor in the lower third of the ureter underwent resection with Boari operation, classic nephroureterectomy with bladder resection was made in 15(65.2%) patients, transurethral resection of the wall of the bladder, ostium and distal ureter followed by nephroureterectomy was performed in 6(26.1%) patients. The latter operative procedure is radical but less traumatic. Five-year survival made up 73.9%.
