“…If the amounts of uric acid are considerable, uric acid or mixed uric acid/COM stones will form. As expected, these types of stones were more prevalent in patients with urinary pH < 5.5 than in those with higher urinary pH (Liebman et al 2007). If the amount of formed uric acid crystals is small, it can be eliminated as asymptomatic crystalluria.…”

PurposeUrinary pH is an important factor linked to renal stone disease and a useful marker in the treatment of urolithiasis. Although the gold standard for measuring urinary pH utilizes a glass electrode and a pH meter, at present dipstick testing is largely used to estimate urinary pH. However, the accuracy and precision of this method may be insufficient for making clinical decisions in patients with lithiasis. The aim of this study is to describe a new device for urinary pH testing.MethodsThe device includes a pH sensor based on differential measurement of an ISFET-REFET pair. The drawbacks associated with this type of configuration, namely short lifetime and manual fabrication, have been overcome in the prototype. An automatic one point calibration is performed when turning on the system. Two buffer solutions were utilized to determine the intra- and inter-day precision of the device. The pH of 30 fresh human urine samples was measured using a pH-meter, a dipstick and the new electronic device.ResultsIn some cases, dipstick measurements differed from those of the pH meter by more than 0.40 units, a clinically relevant discrepancy, whereas none of the measurements made with the new electronic device differed from the results of the pH-meter by more than 0.1 pH units.ConclusionsThis new electronic device has the possibility to be used by stone-formers to control their urinary pH at home, increasing the tools available for stone prevention and prophylaxis.

“…1 In general, patients with a history of gout are at greater risk of forming uric acid stones, as are patients with obesity, diabetes, or complete metabolic syndrome. 2 Moreover, elevated serum urate levels are known to lead to gouty arthritis, tophi formation, and uric acid kidney stones. 3 The incidence of uric acid stones varies between countries and accounts for 5% to 40% of all urinary calculi.…”

“…These were the main factors why dual-energy CT was not further applied in clinical practice. With the introduction of dual-energy dualsource CT the characterisation of urinary calculi has been demonstrated to be feasible [3,[13][14][15][16][17][18][19].…”
