Questions that might arise…
What is the best conservative management?• Analgesia and fluids are the obvious answers, but…
– How much fluid?– Some people use hyoscine as an adjunct to other analgesics —
is this a good idea?– Is there anything else that could be done?– How strong is the evidence supporting our usual practice?

alpha-blockers categorised as
‘Likely to be beneficial’

moderate-quality evidence for using alpha-blockers
full details about the RCTs
(tamsulosin was the most
commonly tested)

no good RCT evidence to
support high-volume iv fluids

Changing management
• Consider adding an alpha-blocker (possibly tamsulosin) to speed up stone explusion
• Avoid anti-spasmodics• Stick with regular iv fluid replacement

Summary• Clinical Evidence can be used to make sure your
practice is up to date– Answers clinical questions– Keeps you informed of new treatments– Demonstrates when existing treatments are not supported by
good evidence
