Abstract
— The authors report on their experience gained in the percutaneous endoscopic treatment of 60 cases of stones in the upper ureter. The stones ranged in dimension from 12 to 15 mm. In 36 patients the push-back attempt was successful and after ultrasound crushing, the stones were removed percutaneously. After unsuccessful push-back in the other 24 patients, anterograde ureteroscopy was performed with crushing, using either Nd: YAG Pulsed Laser or electrohydraulic energy. Their experience shows that a combination of anterograde ureteroscopy and laser stone crushing is a reliable and efficient procedure for the treatment of impacted stones in the upper third of the ureter. In such cases laser crushing gives better results than the electrohydraulic procedure.
