- Renal screening sonography—a comparative study in a portuguese basic emergency servicePublication . Jiménez, Carmen; Barbancho, Narciso; Lobo, Manuel Duarte; João Mário Gonçalves; Corina Hasnas; Miravent, Sérgio; Figueiredo, Teresa; Almeida, Rui; Gomes, Carla Marisa; Ratusneac, IonRenal Point-of-Care Ultrasound (POCUS) is a screening modality that aids in clinical decision-making for patients with suspected renal colic. This study intends to compare the accuracy and pertinence of sonographic findings obtained by a sonographer in a Basic Emergency Service (BES) with the imaging findings at the Referral Hospital (RH). Methods: Thirty-one patients suspected of having renal pathology underwent initial sonography screening with POCUS at the BES and were subsequently referred to the RH for additional imaging examinations. The results of both examinations were compared to verify whether the findings from the BES were confirmed by the radiologist in the RH and to ensure that the patient referrals from BES to RH were appropriate. Results: In our sample, the majority of patients (80%) exhibited varying degrees of pyelocaliceal distension, with nearly half (48%) patients presenting obstructions. A strong association between the sonographic findings in the BES and the RH was found in the variables ‘Dilatation of pyelocaliceal system’ (V = 0.895; P = 0.00), ‘Simple cystic formation’ (V = 0.878; P = 0.000), respectively. There was a statistically significant correlation between BES and RH findings, indicating a strong association between these two variables, respectively (k = 0.890; P = 0.000) and (k = 0.870; P = 0.000). There was also a strong statistically significant correlation in the ultrasonographic findings between BES and RH performers (k = 0.890; P = 0.000 and k = 0.870; P = 0.000). In this research, an achieved sensitivity of 96% and a specificity of 85% were demonstrated in the identification of pyelocaliceal dilatation. Conclusion: Renal POCUS screening successfully detected abnormalities in the urinary system of patients suspected of having renal colic. The sonographic findings at the BES had a good correlation with the complementary imaging results obtained at the RH in Portugal. These results suggest that Radiographers/Sonographers can have an important role in the preliminary assessment of urgent renal pathology in remote areas, contributing to a correct referral and early treatment.
- Pre-hospital Identification of a Giant Bladder Calculus through Screening Sonography: A Case ReportPublication . Miravent, Sérgio; Gomes, Carla Marisa; Simãozinho, Paula; Vaz, Bruna; Lobo, Manuel Duarte; Almeida, RuiIntroduction: Screening ultrasound proves to be remarkably beneficial in pre-hospital settings, particularly in geographically remote areas with technological constraints and no medical specialties. Urological pathology has a high frequency of occurrence in the emergency department and is part of the wide range of occurrences that can benefit from this ultrasound screening as a clinical guide for patients. Case Presentation: In this case, a patient experiencing lower abdominal pain and symptoms of renal colic sought assistance at a basic emergency service facility. Utilizing a renal screening ultrasound executed by a sonographer, the clinical team identified images indicative of a significant bladder calculus. Subsequently, the patient was referred to a referral hospital for a comprehensive evaluation by medical specialties. Conclusion: The images obtained in both health units exhibited congruence, indicating that the screening ultrasound, while not intended to replace the specialized orthodox ultrasound executed by a radiologist, served as a crucial tool for diagnostic presumption, providing consistency in clinical decision-making for referring patients. This capability allowed emergency physicians to promptly transfer a patient requiring urgent further investigation to a referral hospital with compelling and substantiated data. This shift in the approach to patient triage in a remote setting could enhance patient safety.
