5.  Complication rate was 19.2%, 16.2% Clavien I and II, 3% Clavien III, 0% Clavien IV and V.  Two cases presented renal hematoma and one a subcapsular hematoma, all treated conservatively.  Stone free rate in lithiasis cases was 92.5% after one procedure, 97.9% after two procedures and 98.8% after three procedures  During the diagnostic procedures inspection of the entire upper urinary tract was possible in 91% of the cases.

6.  Retrograde flexible ureteroscopic approach is an efficient diagnostic and treatment method for upper urinary tract pathology.  Technological progress during the last years modified method’s indications.  The safety of this procedure is very good, most of the complications being minor.
