Relationship between the Severity of Coronary Artery Disease and Catheter-Associated Urethral Stricture in Patients with Acute Coronary Syndrome


Background: Different arterial segments throughout the vascular system develop similar grades of atherosclerosis concomitantly. Urethral ischemia has been proposed as a cause of urethral stricture. Therefore, we aimed to investigate the relationship between coronary artery disease severity using a SYNTAX score and urethral stricture occurrence after urethral catheterization in patients with non–ST-segment-elevation acute coronary syndrome (ACS).
Methods: This retrospective study consisted of 306 men with urethral catheters that were diagnosed with ACS and underwent coronary angiography between January 2016 and January 2018 in Kars Kafkas University and Osmaniye Government Hospital, Turkey.  Hospital records were reviewed to collect the follow-up data of the patients regarding the occurrence of urethral stricture after urethral catheterization. The study population was divided into 2 groups according to urethral stricture development, and both groups were compared statistically.
Results: SYNTAX scores were significantly higher in patients with urethral stricture than in those without urethral stricture (14.86±7.11 vs. 29.25±9.79; P<0.001). The SYNTAX score (OR=1.27; 95% CI: 1.16–1.39; P<0.001), diabetes, and serum albumin were found to be the independent predictors of urethral stricture. The receiver operating characteristic curve analysis showed that the cutoff value of the SYNTAX score for urethral stricture prediction was greater than 22.5, with 76.7% sensitivity and 85.1% specificity (AUC=0.88, 95% CI: 0.84–0.91; P<0.001).
Conclusion: Coronary artery disease severity graded according to the SYNTAX score is an independent predictor of urethral stricture occurrence in ACS patients with a urethral catheter inserted.
