Ureteral Stone Extraction Utilizing Nondeflectable Flexible Fiberoptic Ureteroscopes

Abstract

Symptomatic ureteral calculi averaging 6 x 7 mm in diameter were removed from the mid upper ureter in 5 patients with a 9F or 8.5F nondeflectable flexible ureteroscope and a basket or forceps. This instrument can be passed through a cystoscope easily and seldom requires dilation of the ureter. These facts, plus its lower cost, make flexible ureteroscopy available to all urologists.
