Rigid ureteroscopy for removal of stones: astudy of 2500 patients

ABSTRACT

Until recently, the only treatment available for ureteric calculi was open ureterolithotomy. However, with the introduction of ureteroscopy, stones can now be removed with Dormia under vision or broken into small pieces with ultrasound, electrohydraulic probe or lithoclast. In this study, we present a review of 2500 cases with ureteric stones of different sizes and at different levels treated with rigid ureteroscopy. The success rate was 92.05% in the lower one-third, 84% in the middle one-third and 26.55% in the upper one-third of the ureter. This method is safe and also results in shorter hospital stay
