Ureteropyeloscopy has become a valuable asset in the diagnosis and treatment in the upper urinary tract. From 1984 to 1991 we performed 1635 ureteropyeloscopies, 180 procedures in a diagnostic intention. Rigid ureteropyeloscopes permit endoscopic access into the ureter and the upper calix, actively deflectable instruments are necessary to visualize the middle and lower calix.
