Objective  To explore the efficacy and safety of gynecological single-port laparoscopic surgery without placing catheters in the daytime.

  Methods  A total of 129 patients with laparoscopic surgery in the Ward of Gynecological Daytime Operation were selected and randomly divided into observation group (n=59) without placing catheters and control group (n=70) with placing catheters during operation and removing catheters at the end of operation. Single-port laparoscopic technique was adopted in all the operations. The incidence of urinary irritation symptoms (the main outcome indicator) and secondary outcome indicators such as urinary tract infection rate, urinary retention rate, incidence of bladder injury, time to first getting out of bed, time to first exhaust and time to first urination were compared between two groups.

  Results  The incidence of postoperative urinary irritation symptoms in the observation group was 8.47%, which was significantly lower than 21.43% in the control group (P < 0.05). There were no significant differences in the time to first getting out of bed, time to first exhaust and time to first urination between the two groups (P>0.05). No urinary retention, urinary tract infection and bladder injury were observed in both groups.

  Conclusion  In the gynecological single-port laparoscopic surgery in the daytime for exfoliation of ovarian cyst, exfoliation of hysteromyoma and fallopian tube related diseases, it is safe and effective to not to place catheters during operation, which can reduce the incidence of postoperative urinary tract irritation.
