Trial summary

In the treatment of kidney stones and upper ureteral stones, flexible ureteroscopic lithotripsy has become the mainstream choice due to its minimally invasive nature and high safety. However, there is still no universal consensus on the use of prophylactic antibiotics before surgery. Read more about this study

About this study

Official title: Comparison of the Post-operative Infection by Using Different Type Prophylactic Antibiotics in Low Risk Patients Who Underwent Retrograde Intrarenal Surgery

In the treatment of kidney stones and upper ureteral stones, flexible ureteroscopic lithotripsy has become the mainstream choice due to its minimally invasive nature and high safety. However, there is still no universal consensus on the use of prophylactic antibiotics before surgery. Taiwan, located in the subtropical region, is one of the areas in the world with a high incidence of urinary tract stones. Currently, there are no established guidelines for the use of prophylactic antibiotics before flexible ureteroscopic lithotripsy in Taiwan. This study aims to evaluate the differences between single-dose, different types of prophylactic antibiotics in generally healthy adult patients undergoing flexible ureteroscopic lithotripsy.

Read the detailed description

This study focuses on flexible ureteroscopic lithotripsy, a procedure commonly used to treat kidney stones and stones in the upper part of the ureter. This surgery is popular because it is minimally invasive and considered very safe. However, there is no clear agreement on whether or which antibiotics should be given to patients before the surgery to prevent infections.

Taiwan is one of the regions in the world with a high rate of urinary tract stones, and because of this, it is especially important to ensure that the best practices are followed to prevent infections during and after the surgery. Currently, there are no official guidelines in Taiwan on which antibiotics should be used before flexible ureteroscopic lithotripsy.

This study aims to compare different types of single-dose antibiotics given before the surgery to see if one is more effective than others in preventing infections. By looking at how different antibiotics perform, the study hopes to provide clearer guidance for doctors in choosing the best antibiotic treatment for patients, ultimately improving patient care and reducing the risk of infections after surgery.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Levofloxacin and Cefmetazole (drug) in people with Retrograde Intrarenal Surgery and Renal Stones, run by National Taiwan University Hospital at 1 site in Taiwan.

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 4 inclusion and 7 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: status not confirmed, as of the sponsor's last update on 19 Dec 2024. 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 Taiwan. 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

Post-operative sepsis (time frame: Postoperative two weeks). 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 NCT06741917, which also lists 1 linked publication.

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 19 Dec 2024.
