Abstract
This study demonstrated the superiority of flexibe ureteroscopy and holmium laser lithotripsy over stented ESWL in the stone free rate and in the post operative complications in the management of large upper ureteric stones causing marked hydroureteronephrosis.
Also this study proved the importance of DJ application prior to ESWL in stone clearance as it has improved the overall stone free rate and decreased the complications in patients with severe hydroureteronephrosis.
To summarize the study, flexible ureteroscopy and holmium laser lithotripsy can be used as the first choice in patients with large upper ureteric stone without fearing the intra operative or post operative complications.
