Comparison of outcome of middle and lower calyceal access for renal pelvis stone in percutaneous nephrolithotomy

Abstract

A prospective study conducted at Dhaka Medical College Hospital over 12 months aimed to evaluate the efficacy and safety of middle and lower calyceal access during percutaneous nephrolithotomy (PCNL) for renal pelvis stones. Seventy patients meeting inclusion and exclusion criteria were purposively selected and divided into two groups: Group 1 underwent PCNL via middle calyceal access, and Group 2 via lower calyceal access. Data on clinical history, physical examination, and procedure-related parameters were collected, analyzed using SPSS version 24, and presented in tables and graphs. Both groups had no significant differences in age, sex, or stone size. However, significant differences were observed in procedure-related metrics, including shorter access duration (p=0.01), reduced operative time (p=0.019), lesser hemoglobin drop (p
