title: Ureteroscopy: results and complications.
abstract: The results and complications of 100 consecutive ureteroscopy studies are reported. Introduction through the orifice or the intramural ureter failed in 11 per cent of the patients and in 14 per cent the ureteroscope could not be advanced up to the level of the lesion. Ureteroscopy was successful in 75 per cent of the patients and stone extraction was successful in 69 per cent. Complications occurred in 9 patients: 4 had an uncomplicated urinary tract infection, 4 had a ureteral perforation and 1 presented with ureteral stenosis at the site of the extracted stone a few weeks later. At followup 1 to 3 months after ureteroscopy clinical examination, excretory urography and/or renography revealed no further late sequelae.
