Randall kidney stone forceps
A long forceps with curved jaws (lightly, three-quarter, or fully curved depending on size), fenestrated tips, and a ratcheted handle lock; available in several lengths (18-22 cm) and degrees of curvature.
How it is used
Introduced directly into the renal pelvis or calyces through an open nephrotomy or pyelotomy to grasp and remove whole stones or large fragments under direct vision or palpation; unlike the already-catalogued Dormia basket or nephroscope, this is an open-surgery instrument, not an endoscopic one.
Clinical tip
Still used in open nephrolithotomy for very large or complex staghorn calculi when PCNL or endoscopic surgery is not feasible or has failed.
