Abstract: ［Abstract］ Objective〖HTSS〗To explore the effect of external fixation of urethral tube and abdomen in patients after greenlight photoselective vaporization of the prostate（PVP）. 
〖WTHZ〗Methods〖HTSS〗A total of 172 patients who underwent PVP were selected by objective sampling, 83 patients in the control group and 89 patients in the observation group. The control group received routine external fixation of upper 1/3 of the lateral thigh catheter, and the observation group received abdominal external fixation of the catheter. The incidence of urine color change, satisfaction during indwelling and the firmness of external fixation were compared between two groups.
〖WTHZ〗Results〖HTSS〗The occurrence rate of urine color reddening in the observation group was significantly lower than that in the control group. The satisfaction and total satisfaction of patients in the observation group in terms of comfort, convenience, privacy protection were higher than those in the control group. The firmness of external fixation device in the observation group was better than that in the control group, and the difference was statistically significant(P＜0.05).
〖WTHZ〗Conclusion〖HTSS〗Fixing urinary catheter on the abdomen in patients after PVP can reduce the incidence of bleeding, promote the recovery of patients, and improve the satisfaction during the period of indwelling catheter, which is worthy of clinical promotion.
