IMPACT OF DIFFERENT BODY POSITIONS ON PERCUTANEOUS NEPHROLITHOTRIPSY IN PATIENTS WITH COMPLEX NEPHROLITHIASIS
Objective To investigate the impact of lithotomy position combined with oblique supine position,oblique supine position,and complete prone position on percutaneous nephrolithotomy in patients with complex nephrolithiasis.Methods A total of 180 patients with complex nephrolithiasis undergoing percutaneous nephrolithotripsy were randomly and equally divided into three groups:group A (lithotomy position combined with oblique supine position),group B (oblique supine position),and group C (complete prone position).The clinical outcome and complications of three groups were observed and compared.Results Group A had a significantly shorter time of operation than groups B and C,and the time of operation in group B was significantly shorter than that in group C (F =8.753,P<0.01).There were no significant differences in intraoperative blood loss and length of hospital stay between three groups (P>0.05).The comfortable rate of intraoperative body position in group A was significantly higher than that in groups B and C (x2 =17.252,18.634;P<0.01),but there was no significant difference in the comfortable rate between groups B and C (P>0.05).Moreover,there were no significant differences in stone clearance rate and complication incidence between the three groups (P>0.05).Conclusion Lithotomy position combined with oblique supine position,oblique supine position,and complete prone position have similar impact on percutaneous nephrolithotripsy in patients with complex nephrolithiasis.However,lithotomy position combined with oblique supine position can shorten the time of operation and improve the intraoperative comfort of patients compared with the other two body positions.
