Nephrolithiasis is a frequent problem that can cause serious morbidity. When associated with an underlying metabolic disorder the recurrence rate is higher. Hypocitraturia is estimated to be present in 20-60% of cases. Several secondary causes are known. Potassium citrate is the primary treatment. In the case we present here we emphasise the need for metabolic screening, focussing on hypocitraturia, a less well-known cause of nephrolithiasis.
