Abstract:
Objective To provide imaging anatomy basis for percutaneous nephrolithotomy ( PCNL) by measuring relative displacement and changes in anatomical position of kidney and colon under the prone and low-oblique supine positions.Methods Forty-six patients scheduled for PCNL underwent 64-slice spiral CT scan under the prone and low-arch oblique supine position before the PCNL.The horizontal distance of kidney and colon,the distance from colon and analog puncturing line,the distance between the kidney and colon were measured and compared between the 2 positions.Results The distance from colon and analog puncturing line under the low-oblique supine and prone positions were as follows,the left (26.56 ±15.36) mm versus (12.25 ±13.16) mm (t=3.527,P<0.05),the right (25.85 ±14.26) mm versus (13.57 ± 12.53) mm (t=3.234,P<0.05).The differences of the rest distances between the 2 positions were not significant ( P>0.05).Conclusions The distance between colon and analog puncturing line increases in the low-arch oblique supine position,because the colon shifts to the ventral.The PCNL in low-arch oblique supine position may reduce the incidence of colon injury,and improve surgical safety.
