This study states that Stone weight has been accounted for as an autonomous indicator of sans stone rate after percutaneous nephrolithotomy (PCNL); anyway no agreement exists on a normalized technique for estimating stone weight. As of late, stone volume has been upheld as the most exact methods for estimating stone weight. We intended to look at changed estimating strategies for stone weight and to recognize the prescient estimation of each for results after PCNL. We played out a review audit of a forthcoming information base of patients who went through PCNL somewhere in the range of 2006 and 2013. A preoperative CT and postoperative imaging at release were vital for qualification. Stone weight was evaluated through four unique ways on CT pictures: (1) aggregate stone width; (2) assessed SA (surface region) determined as longest × orthogonal diameter × π/4; (3) manual layout of stone and PC SA count; and (4) computerized 3D volume figuring utilizing explicit programming. Essential result was sandstone status (SFS) at release. Optional results included employable time and the requirement for an auxiliary method. Relapse examination and collector working trademark bend investigation were utilized to assess the prescient estimation of every technique.
