Prevention of Urinary Stones with Hydration (PUSH) Randomized Trial

A 1,658-participant RCT demonstrating the difficulty of sustained hydration behavior change in stone formers — supporting the value of building hydration into a daily supplement routine. This trial did not test KSPtabs or citrate supplementation.

Practical Considerations

Citrate support only works when patients can stay with it.

Prescription potassium citrate can be effective, but cost, pill size and adherence can be barriers. KSPtabs provides citrate-containing alkalinizing agents in an effervescent format designed to become part of the patient's daily hydration.

Factor Rx Potassium Citrate KSPtabs
Alkalinizing agents Prescribed dosing varies 15 mEq / tablet
Format Tablets / Capsules Effervescent drink
Hydration built in No Yes
Prescription Required OTC
Patient cost* Varies by dose / coverage ~$50 / month

*Based on typical U.S. retail pricing (~$50/month). Individual costs may vary.

2026 AUA Guideline
The Guideline Describes Your Patients

The 2026 AUA Guideline identifies exactly who KSPtabs was built for.

Part I recommends dietary citrate supplementation for calcium stone formers with hypocitraturia — the core indication KSPtabs addresses, delivering 15 mEq of potassium citrate per tablet in a format patients use daily. Part II supports pharmacologic citrate therapy for recurrence prevention and long-term follow-up. Where cost and pill burden cause patients to abandon prescription citrate, KSPtabs provides a guideline-aligned OTC option at ~$50/month with built-in hydration. Part III covers surgical intervention — the outcome medical management is designed to prevent. Every patient who stays adherent to citrate therapy is a patient who may avoid a procedure.

Clinical Application
Does your patient
fit the profile?
KSPtabs was built for specific patient presentations. See the full clinical guide — including patient selection criteria, 24-hour urine targets, and prescribing considerations.
See Which Patients Benefit → Patient selection criteria, prescribing notes & sample request
Hypocitraturia
Low urinary citrate documented on 24-hour collection — the core indication KSPtabs was developed to address.
Recurrent calcium stone formers
Patients seeking additional citrate support between or after stone events.
Low urine pH / uric acid risk
Patients where urinary alkalinization is part of the management strategy.
