External validation of the CHOKAI score for the prediction of ureteral stones: A multicenter prospective observational study.

OBJECTIVE: The CHOKAI and STONE scores are clinical prediction rules to predict ureteral stones in patients presenting with renal colic. Both systems contribute to reducing diagnostic radiation exposure; however, few studies have compared the two scoring systems. Therefore, we aimed to compare these systems and assess their diagnostic accuracy for ureteral stones. METHODS: This was a multicenter prospective observational study performed between 2017 and 2018, including patients aged >15 years with renal colic and suspected with ureteral stones. We calculated the CHOKAI and STONE scores of each patient based on their medical interviews and physical and laboratory findings. Primary outcome was differences in the area under the receiver operating characteristic curve in each model, and secondary outcome was diagnostic accuracy at the optimal cut-off point. RESULTS: Of the 124 patients included, 84 were diagnosed with ureteral stones. The area under the curve of the CHOKAI score was 0.95, showing a sensitivity of 0.93, specificity of 0.90, positive likelihood ratio of 9.3, and negative likelihood ratio of 0.079, at an optimal cut-off point of 6. The area under the curve of the STONE score was 0.88, showing a sensitivity of 0.68, specificity of 0.90, positive likelihood ratio of 6.8, and negative likelihood ratio of 0.36, at an optimal cut-off point of 9. Thus, the area under the curve was significantly higher for the CHOKAI score than for the STONE score (p = 0.0028). CONCLUSIONS: The CHOKAI score has a diagnostic performance superior to that of the STONE score in this population.

The effectiveness of hybrid treatment for sever multiple trauma: a case of multiple trauma for damage control laparotomy and thoracic endovascular repair.

BACKGROUND: Time is a crucial factor for the successful early management of the multi-trauma patient. Hybrid operating theaters, which support the integration of surgical treatment and interventional radiology, provide opportunities to reduce the time-to-surgery for life threatening conditions. CASE PRESENTATION: We describe the early successful treatment of a 54-year-old male who sustained multiple injuries when he was hit by a 1000 kg bale of wheat that fell from a height. He was admitted with hemorrhagic shock due to intra-abdominal bleeding, an unstable fracture of the pelvis, and blunt aortic injury, which was considered to be at high risk of rupture. External fixation was applied to the pelvis in the resuscitation bay, and the patient was transferred to a hybrid operating theater for treatment of both the intra-abdominal hemorrhage and blunt aortic injury. Damage control laparotomy and thoracic endovascular aortic repair were performed uneventfully. CONCLUSIONS: Hybrid treatment, which combines emergency surgery and intraoperative interventional radiology, provides a prompt and appropriate management approach for the treatment of patients with severe multiple trauma and may improve patient outcomes.
