Jackstone calculus
Type of urinary tract stone
From Wikipedia, the free encyclopedia
Jackstone calculus is a type of urinary tract stone characterized by its unique appearance with stippled and spiculated contour, resembling a toy jack.[1][2] Jackstone calculi are composed of calcium oxalate dihydrate, which gives them their irregular shape.[3] They are often detected in radiological investigations or cystoscopy.[4]
