Empowering you with simple tools to support your healing and improve outcomes after shockwave lithotripsy.
Stay Ahead of Stone Formation
Staying well-hydrated is essential to reduce your risk of future stones. This tool helps you calculate your ideal daily fluid intake based on your body weight, activity level, and environmental factors—keeping your kidneys flushed and healthy.
Track Your Progress, Reduce Anxiety
Curious how long it might take for stone fragments to pass after treatment? This tool offers an estimate based on typical timelines for stone size and location—helping you stay informed and better prepared during your recovery.
Lithotripsy Academy is an educational initiative of Endourology Academy, focused on advancing knowledge and training in Shock Wave Lithotripsy (SWL) through evidence-based learning and clinical expertise.

Disclaimer: This calculator provides an estimated prediction for SSP based on the MIMIC study. It should not be used in isolation but as part of an overall decision-making process involving multidisciplinary professionals.
Evidence: MIMIC was a multi-centre cohort study assessing the predictors of spontaneous stone passage amongst 4171 patients in 71 sites across 7 different countries in 6 months. To access results from this study, please click here Following the results from MIMIC, the impact of these predictors on the probability of spontaneous stone passage was analysed. Logistic regression was employed to achieve corrected beta-coefficients for each predictor’s impact on probability of spontaneous stone passage. This formed the basis for constructing this risk calculator. We hope that this will aid clinical decision-making when treating patients with acute ureteric colic.
Important Disclaimer:The MIMIC Spontaneous Stone Passage (SSP) Prediction calculator provides an estimated prediction for SSP based on collected multi-centre data. This nomogram is an adjunctive tool developed to guide patient counselling on the predicted probability of SSP. It should not be used in isolation but as part of an overall decision-making process involving multidisciplinary professionals. Interpretation of the nomogram output has to be taken in context of the following limitations; (1) it does not define probability thresholds to perform interventions; (2) it does not provide estimations on time to SSP; (3) it does not detail the opportunity cost (i.e. risk of complications from intervening or additional resource use) associated with treatment strategy at each prediction point; (4) it has been developed and temporally validated on a dataset with cases only from UK, Australia, Ireland and New Zealand. External validation in an independent population will be a future study.
