Background: Iatrogenic urethral injury is a well-known risk of urinary catheter insertion. Associated morbidities include stricture formation, catheter associated infection, risk for instrumentation, and extended length of stay. Yet, insufficient attention is paid to its prevention. Objective: This study aimed to assess the effectiveness of a computerized ordering system in reducing iatrogenic urethral injuries in men at high risk for iatrogenic urethral injury from traumatic catheterization. Methods: A pre-post study was performed to assess the impact of a computerized ordering system that recommended a 16 Fr Coudé-tip catheter be used instead of the standard 16 Fr Foley catheter for men at high risk for difficult catheter insertion. The intervention was implemented in October 2012. The rates of traumatic and non-traumatic insertion consults were compared between the pre-intervention (10/1/2010-09/30/2011) and post-intervention (10/1/2012-9/30/2013) time periods. Results: The results showed that 78.5% of patients with iatrogenic urethral injury possessed at least one identified risk factor for difficult catheterization. There was no significant difference in frequency of traumatic or non-traumatic insertion consults between the pre- and post-intervention cohorts. Conclusion: The current study highlights the possibility of preventing traumatic insertions by targeting men at high risk for iatrogenic injury. Without a simultaneous plan for improving catheter placement awareness and training, any change in the ordering process is unlikely to succeed on its own.

Introduction: Iatrogenic aortocoronary dissection (ACD) is a nightmare in interventional cardiology. Although ACD is rarely reported, the real-world prevalence is suspected of being higher due to unreported cases. The right coronary artery (RCA) ostium is involved in the majority of cases, and dissections are usually limited to the aortic sinus in half of the clinical presentations. There are different treatment strategies, including interventional approaches, surgery, and medical follow-up. Immediate stent deployment to the coronary osteum might be a life-saving procedure, and the surgical approach should be preferred in occasions of dissection extension beyond the sino-tubular junctions. Catheter trauma and subintimal progression of guidewires are major causes of ACD occurrence.Case Presentation: Herein presented is a case report of spontaneous ACD observed after contrast injection to the RCA ostium. Approximately 8 cc of radiocontrast agent was injected into the right coronary ostium. Antegrade and retrograde dissections which extended to the distal RCA and aortic root were observed. The right sinus of Valsalva was stained with contrast agent, and the border of the stained area was extended to the sinotubular junction. Medical follow-up was proposed by the heart team. Close follow-up with echocardiographic examination indicated the complete regression of the dissection.Conclusion: The authors consider conservative follow-up with echocardiogaphy rather than computed tomography and/or magnetic resonance to be the most appropriate imaging technique for use with stable patients.
