[Correspondence] Ureteric colic and clinical evidence

A fascinating aspect of clinical research is that it sometimes produces interesting findings that go against the norm. Robert Pickard and colleagues (July 25, p 341),1 for instance, published the results of the SUSPEND trial. Contrary to previous data, showing the benefit of medical expulsive therapy (MET) in the management of patients with ureteric colic secondary to ureteral stones smaller than 1 cm,2 the authors showed that neither tamsulosin 0·4 mg daily nor nifedipine 30 mg daily are effective at decreasing the need for further treatment at 4 weeks.
