RecommendationAt initial assessment, offer men with LUTS a serum creatinine test (plus estimated glomerular filtration rate [eGFR] calculation) only if you suspect renal impairment (for example, the man has a palpable bladder, nocturnal enuresis, recurrent urinary tract infections or a history of renal stones).
Relative values of different outcomesThe GDG considered that an improvement in symptoms was the most important outcome.
Trade off between clinical benefits and harmsThe GDG felt in the absence of evidence detecting a benefit this test should not be routinely offered.
Economic considerationsThere are costs associated with this test which does not add any important information except in the case of clinically suspected renal impairment.
Quality of evidenceNo clinical or economic studies were found and these recommendations were based on the consensus opinion of the GDG.
Other considerationsThe results of testing need to be interpreted with regard to the age, sex and race of the man.
