The best drainage method of three-cavity catheter after robot-assisted laparoscopic radical prostatectomy

Objective To explore the best draining method of three-cavity catheter after robot-assisted laparoscopic radical prostatectomy.

Methods A total of 120 patients with robot-assisted laparoscopic radical prostatectomy were selected and divided into observation group (n=60) and control group (n=60) according to operation sequence. The observation group received double channel drainage with three-cavity catheter after operation, while the control group received single channel drainage. The incidence conditions of acute urinary retention, anastomotic leakage and intestinal obstruction after operation were compared between the two groups; the indwelling time of pelvic drainage tube and three-cavity urinary catheter and the average postoperative hospital stay were compared between the two groups; the Self-rating Anxiety Scale (SAS) was used to evaluate the postoperative anxiety status of patients in both groups.

Results In the observation group, there were 12 cases of acute urinary retention occurred (20.00%), 5 cases of anastomotic leakage (8.33%) and 2 cases of intestinal obstruction (3.33%); in the control group, there were 25 cases of acute urinary retention (41.67%), 13 cases of anastomotic leakage (21.67%) and 5 cases of intestinal obstruction (8.33%). There were significant differences in incidence rates of acute urinary retention and anastomotic leakage between the two groups (P < 0.05). In the observation group, the indwelling time of pelvic drainage tube, the indwelling time of three-cavity catheter, the average postoperative hospital stay and the postoperative SAS score were (3.62±0.96) days, (11.98±3.26) days, (5.23±0.81) days and (56.73±4.65) points respectively, which were significantly shorter or lower than (4.53±1.65) days, (13.72±4.26) days, (6.25±1.99) days and (58.93±7.19) points in the control group (P < 0.05).

Conclusion The best drainage method of three-cavity catheter after robot-assisted laparoscopic radical prostatectomy is double channel drainage, which can reduce the incidence rate of postoperative acute urinary retention and anastomotic leakage, shorten the indwelling time of pelvic drainage tube and three-cavity catheter, shorten the average postoperative hospital stay, and relieve the postoperative anxiety level of patients.
