About this study
Given the high recurrence of urolithiasis in patients, the search for less aggressive and preventive treatments is increasingly necessary. Renalof® is presented as an alternative to herbal medicine being a product that, due to its diuretic and demineralization properties of kidney stones, has been widely used in this patient population, disintegrating and eliminating calcium oxalate and struvite stones in a painless in the genitourinary system.
With the objective of determining the efficacy of this therapy, an observational, prospective, randomized, single-blind, two-arm study was carried out: treatment group with Renalof® and control group, placebo.

Given the high recurrence of urolithiasis in patients, the search for less aggressive and preventive treatments is increasingly necessary. Renalof® is presented as an alternative to herbal medicine being a product that, due to its diuretic and demineralization properties of kidney stones, has been widely used in this patient population, disintegrating and eliminating calcium oxalate and struvite stones in a painless in the genitourinary system.
With the objective of determining the efficacy of this therapy, an observational, prospective, randomized, single-blind, two-arm study was carried out: treatment group with Renalof® and control group, placebo.
The treatment group consists of 120 patients over 18 years of age, of both sexes, with a diagnosis of urolithiasis less than 10 mm in diameter, present throughout the entire reno-uretero-bladder path, diagnosed by ultrasound, renal CT and urography . The Renalof® product was administered at a dose of 650 mg daily for 3 months and the presence of stones in any location of the reno-ureteral tract was evaluated using one of the diagnostic means mentioned in monthly consultations. The second group, treated with placebo corresponding to 35 people constituting 30% of the universe. The study period was from August 2019 to July 2020 at the Hospital Escuela Antonio Lenin Fonseca and the Seniors clinic, in the city of Managua, Nicaragua.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
RenalofDietary supplement
A total of 120 patients treated with the study product Renalof® at a dose of 650 mg twice daily were followed for 4 months. A preliminary analysis of the types of stones present in the study patients was performed according to the main compound, using a biophysical profile by biochemical analysis and the clinical characteristics, medical history and biochemical profile of the creatinine values of the test patients. Imaging and quality of life tests were carried out during the trial to check the efficacy and possible adverse effects of the test product in patients with kidney stones.
PlaceboOther
A total of 35 patients treated with Placebo at a dose of 650 mg twice daily were followed for 4 months. A preliminary analysis of the types of stones present in the study patients was performed according to the main compound, using a biophysical profile by biochemical analysis and the clinical characteristics, medical history and biochemical profile of the creatinine values of the test patients. Imaging and quality of life tests were carried out during the trial to check the efficacy and possible adverse effects of the test product in patients with kidney stones.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Given the high recurrence of urolithiasis in patients, the search for less aggressive and preventive treatments is increasingly necessary. Renalof® is presented as an alternative to herbal medicine being a product that, due to its diuretic and demineralization properties of kidney stones, has been widely used in this patient population, disintegrating and eliminating calcium oxalate and struvite stones in a painless in the genitourinary system.
With the objective of determining the efficacy of this therapy, an observational, prospective, randomized, single-blind, two-arm study was carried out: treatment group with Renalof® and control group, placebo.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Renalof in people with Renal Injury and Kidney Injury, run by Catalysis SL at 1 site in Nicaragua.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Nicaragua. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
kidney stone clearance with Renalof® treatment compared to placebo (time frame: 4 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04695951, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jan 2021.
