[Laser-assisted transurethral resection of ureteral occlusions].

After transurethral resection across the ureteral ostium a scared stenosis or complete occlusion is possible and its transurethral recanalization is dangerous. Therefore, a new concept with utilisation of laser light is presented. After percutaneous renal punction the laser light fiber is placed antegrade into the ureter near the stenotic ostium and the stenosis is resected transurethrally under fluoroscopy onto the laser light spot. Thereafter a splint is placed transrenal into the bladder for 3 weeks. The presented technique could minimize the operative expense.
