Abstract
New fiberoptic scopes, originally designed for biliary tract operations, were used in 23 cases [in humans] for removal of residual calculi at pyelolithotomy and for examination of the renal pelvis and ureter. External diameters of the scopes are 6.6 mm (CHF-X1) and 4.5 mm (CHF-X2). Water irrigation and forceps manipulation were performed simultaneously with the CHF-X1 scope, but only irrigation was done with the CHF-X2 scope. Scopes were reliable and allowed easy endoscopic forceps manipulation. Improvements for an ideal fiberoptic nephroscope were discussed.
