[Tumors of the upper excretory tract. Cases contribution and review of the literature].

Authors reviewed 11 cases of urothelial tumors of the upper urinary tract. Clinical history, diagnostic procedures and surgical treatment of 8 patients with tumor in the renal pelvis and of 3 patients with ureteral tumor are described. The aspecificity of clinical finding and the possibility of different urinary tract affections may be responsible of many difficulties in doing early diagnosis using routinary instrumental investigations. Nephroureterectomy is most frequently performed as surgical treatment. The results are correlated with the stage of infiltration of surrounding tissues by tumor. It is necessary an early clinical study of the patients with signs or symptoms referring to urinary tract (hematuria, abdominal pain) using excretory urogram, cystoscopy and urinary cytology in order to lower the delay of surgical procedure after the evidence of clinical finding.
