Comparison of anatomical changes in computed tomography CT scan in supine position and prone position with respect to percutaneous nephrolithotomy PCNL.

Objective To compare the anatomical organ positional changes renal access tract length and maximum renal access angle in relation to the kidney in supine and prone positions through CT scan images. Methods CT Urography was performed in 52 patients with various urological complaints in supine and delayed images in prone position. A comparison in both supine and prone position was done to analyse the organ interposition pleural interposition, mean access tract length, maximum renal access angle for PCNL.
