To investigate the effect of lateral decubitus catheterization after lumbar anesthesia in male patients undergoing hip replacement.

A total of 100 male patients undergoing hip replacement under intraconical anesthesia were included in this study, the patients with urethral deformity or prostatic hyperplasia were excluded. According to the admission number, the patients were divided into the observation group and the control group with 50 cases in each group by even and odd numbers. The observation group underwent lateral decubitus catheterization after successful induction of anesthesia, and the control group were changed to supine position for indwelling urinary catheter. The urethral injury, success rate of primary urethral catheterization, operation preparation time and unilateral anesthesia effect were compared between the two groups.

There were three cases (6%) and four cases (8%) of urethral injury in the observation group and the control group, respectively, with no significant difference (P>0.05). There was also no significant difference in the success rate of one-time catheterization between the two groups (P>0.05). The preparation time of operation(t=20.802) and the effect of unilateral anesthesia (χ²=59.278) in the observation group were better than those in the control group, and the difference was statistically significant (both P<0.01).

Lateral decubitus urethral catheterization after anesthesia for male patients undergoing hip replacement is beneficial to shorten the operation preparation time and improve the effect of anesthesia without increasing urethral injury.
