Abstract
Objectives: To develop a nomogram that could predict spontaneous stone passage (SSP) in patients presenting with acute ureteric colic who are suitable for conservative management. Patients and Methods: A 2517 patient dataset was utilised from an international multicentre cohort study (MIMIC, A Multi-centre Cohort Study Evaluating the role of Inflammatory Markers In Patients Presenting with Acute Ureteric Colic) of patients presenting with acute ureteric colic across 71 secondary care hospitals in the UK, Ireland, Australia, and New Zealand. Inclusion criteria mandated a non-contrast computed tomography of the kidneys, ureters, and bladder. SSP was defined as the ‘absence of the need for intervention’. The model was developed using logistic regression and backwards selection (to achieve lowest Akaike's information criterion) in a subset from 2009–2015 (n = 1728) and temporally validated on a subset from 2016–2017 (n = 789). Results: Of the 2517 patients, 1874 had SSP (74.5%). The mean (SD) age was 47 (14.7) years and 1892 were male (75.2%). At the end of the modelling process, gender: male (odds ratio [OR] 0.8, 95% confidence interval [CI] 0.64–1.01, P = 0.07), neutrophil count (OR 1.03, 95% CI 1.00–1.06, P = 0.08), hydronephrosis (OR 0.79, 95% CI 0.59–1.05, P = 0.1), hydroureter (OR 1.3, 95% CI 0.97–1.75, P = 0.08), stone size >5–7 mm (OR 0.2, 95% CI 0.16–0.25, P < 0.001), stone size >7 mm (OR 0.11, 95% CI 0.08–0.15, P < 0.001), middle ureter stone position (OR 0.59, 95% CI 0.43–0.81, P = 0.001), upper ureter stone position (OR 0.31, 95% CI 0.25–0.39, P < 0.001), medical expulsive therapy use (OR 1.36, 95% CI 1.1–1.67, P = 0.001), oral nonsteroidal anti-inflammatory drug (NSAID) use (OR 1.3, 95% CI 0.99–1.71, P = 0.06), and rectal NSAID use (OR 1.17, 95% CI 0.9–1.53, P = 0.24) remained. The concordance-statistic (C-statistic) was 0.77 (95% CI 0.75–0.80) and a nomogram was developed based on these. Conclusion: The presented nomogram is available to use as an on-line calculator via www.BURSTurology.com and could allow clinicians and patients to make a more informed decision on pursuing conservative management vs early intervention.
