Abstract
PURPOSE: The NMOC-3WAY catheter® is a novel urinary catheter for men that can be used to inject a local anesthetic into the urethra. We sought to assess whether the injection of a local anesthetic into the urethra via the NMOC-3WAY catheter® would reduce catheter-related bladder discomfort (CRBD) after endovascular aneurysm repair (EVAR). METHODS:Adult male patients who underwent elective EVAR for abdominal aortic aneurysms were randomly assigned to the 2% lidocaine group and the normal saline group (control group). CRBD was evaluated at 0, 1, 2, 4, and 6 h after surgery. The primary outcome was the incidence of CRBD at 0 h after surgery. RESULTS: Data for 37 patients (19 in thelidocaine group and 18 in the control group) were analyzed. CRBD was observed at 0 h in six patients (31.6%; mild, n = 5; moderate, n = 1) in the lidocaine group and in five patients (27.8%; mild, n = 1; moderate, n = 3; severe, n = 1) in the control group. The control group showed a tendency to have severe CRBD at 0 h, although there was no significant difference in either the incidence (P = 0.80) or severity (P = 0.21) of CRBD between the two groups. CONCLUSION: Our results suggest that the use of the NMOC-3WAY catheter® for the injection of 2% lidocaine into the urethra does not reduce the incidence of CRBD immediately after EVAR. However, it may reduce moderate or severe CRBD that may lead to postoperative distress and agitation.
