What are the clinical effects of the different emergency department imaging options for suspected renal colic? A scoping review

Clinical Score Application for Abdominopelvic Computed Tomography Used in the Diagnosis of Renal Colic Patients

Background To develop risk scoring for the use of computed tomography (CT) imaging using the visual analog scale (VAS), physical examination, and laboratory findings of renal colic patients admitted to the emergency department (ED).

Materials and Methods This is prospective observational study. Among the patients who presented to the ED with abdominal or flank pain, patients who were scheduled for CT imaging for urolithiasis were included in the study. The mean VAS pain scores, physical examination findings, laboratory parameters, and macroscopic and microscopic values in urinalysis were compared between the two groups with and without stones on CT.

Results Of the 196 urolithiasis patients included in the study, 165 had ureteral stones, 76 had renal stones, and 45 had renal and ureteral stones. While the difference between the urine erythrocyte averages of the two groups was borderline significant (p = 0.04), there was a high difference between the urinary hemoglobin amounts (p < 0.001). In patients with urinary system stone disease, hydronephrosis, and ureteral dilatation, hemoglobin ++ and above were more significant (p < 0.001). For ureteral stones, pain intensity increased as the size increased (r = 0.34 p < 0.001). White blood cells > 10,000 103/mL, and C-reactive protein (CRP) ≤ 5 mg/L were more significant in patients with acute renal colic.

Conclusions Although we cannot develop a clinical scoring system for renal colic patients, the meaningful results we found for urinary stone disease can be used in a newly developed scoring system. It can be used in new scoring systems in the ED using a high VAS score, presence and amount of urine hemoglobin, CRP) ≤ 5 mg/L, and creatinine value.

Barriers in Managing Acute Ureteric Colic Clinical Review and Commentary

With the global prevalence of urolithiasis increasing, the presentation of acute ureteric colic to emergency departments (ED) poses a significant burden on healthcare systems globally. Management strategies for ureteric colic encompass medical expulsion therapy and various interventional modalities aimed at urinary diversion or definitive stone management. By examining potential or established barriers to managing acute ureteric colic, we can minimise strain on healthcare providers while maintaining patient outcomes. This review aims to assess barriers to the management of acute ureteric colic through a comprehensive overview of the current literature. Acute ureteric colic barriers will be assessed throughout a patient's disease progression, borrowing a conceptual framework used to assess barriers in cancer care management. Barriers will be discussed in the context of patient-centred access to healthcare, clinical evaluation and diagnosis, and management. Numerous barriers to healthcare have been identified throughout the natural course of acute ureteric colic, both specific and non-specific. Patient-centred barriers typically arise during the initial onset of acute ureteric colic. Originating from patient awareness and access to healthcare, they include barriers founded on race inequalities, cultural beliefs, geographic location, transportation, and the concept of a universal standard of healthcare. Having accessed healthcare, barriers in the management of acute ureteric colic next occur during the clinical evaluation and diagnosis period. These are typically associated with clinical assessment or diagnostic imaging delays, including underutilisation of ultrasound, nurse-led pathways for faster clinical reviews, and general ED delays. The final period during acute ureteric colic management correlates to clinical management. The inherent unpredictable course of ureteral stones leads to poor prognostication and failed initial management modalities. Additionally, this period deals with periprocedural delays and preventative health. Barriers to the management of acute ureteric colic arise during a patient's journey through accessing healthcare. Reviewing barriers allow further research into areas requiring modification to expedite care and improve outcomes.
