Use of disposable painless silicone urethral catheter during urological surgery for male patients: a randomized controlled study.

Abstract

Objective: The objective of this study is to evaluate the benefits of placing a disposable, painless silicone urethral catheter in male patients undergoing urological surgery.

Methods: A total of 246 male patients who were scheduled to undergo elective urological surgery under general anesthesia were randomly allocated to the observation and control groups. Patients in the observation group received a disposable, painless silicone urethral catheter connected to an analgesic pump infusing 50 mL of 2% lidocaine at 2 mL/h. The control group received a standard silicone urethral catheter post-surgery. Pain scores, the incidence and severity of catheter-related bladder discomfort (CRBD), sedation scores at 0, 1, 6, 12, and 24 h post-surgery, satisfaction scores at 24 h post-surgery, and postoperative complications were recorded.

Results: The incidence of CRBD among patients in the observation group at 1, 6, and 12 h post-surgery was significantly lower than in the control group (at 1 h: 15.25% vs. 28.23%, respectively; p = 0.021; at 6 h: 8.47% vs. 20.16%, respectively; p = 0.010; at 12 h: 4.24% vs. 12.90%, respectively; p = 0.017). The severity of CRBD was also significantly lower in the observation group at 0 and 1 h post-surgery (p = 0.012 and p = 0.026, respectively). Pain and sedation scores at 1, 6, and 12 h post-surgery were significantly lower among patients in the observation group compared to those in the control group. Although there were no significant differences in postoperative complications, patients in the observation group reported significantly higher satisfaction scores (p < 0.001).

Conclusions: The placement of a disposable painless silicone urethral catheter in male patients during urological surgery was effective in reducing the incidence and severity of postoperative CRBD, relieving pain, and improving patient satisfaction without clinically significant adverse reactions.
