“… examined 1 028 patients discharged from a US emergency department, where, serendipitously, 50% were prescribed MET and 50% were not, and found that rate of surgery was identical. The recent MIMIC trial found no beneficial effect of MET in a 71‐centre UK collaborative, which examined 3 127 patients conservatively managed for ureteric colic . The present study is unique in actually withdrawing MET from protocols and comparing whole cohorts over time, but the observations of lack of efficacy are consistent.…”
