[Transuteral ureterorenoscopy].

The endoscopy has come a long way since the first works by BOZZINI in 1806 and considering that the eye guides all the other senses and confirms their impressions, with the introduction of the transurethral ureterorenoscopy, the urologist can now see the entire ureter, the renal pelvis, the infundibuli and calices, thus enabling him to confirm or rule out the pathology in a non-aggressive way in cases in which only a surgical operation would have done this.
