Summary

This trial compares short vs long pre-op antibiotics for patients at risk of infection during ureteroscopy to test if there's any difference in safety and efficacy.

Who is the study for?
This trial is for adults over 18 with kidney stones who are at moderate to high risk of infection and planning to undergo ureteroscopy. They may have a stent, nephrostomy tube, or use catheters like foley or suprapubic. People with asymptomatic bacteriuria, bowel interposition, or immunosuppression can join. Pregnant individuals, those with active infections or recent non-study antibiotics cannot participate.
What is being tested?
The study compares the effectiveness of taking antibiotics for two days versus seven days before ureteroscopy in preventing post-operative infections. It's a randomized controlled trial aiming to see if a shorter antibiotic course is just as good as a longer one for patients at higher risk of complications.
What are the potential side effects?
Potential side effects from the antibiotics could include allergic reactions, gastrointestinal issues like nausea and diarrhea, yeast infections due to disruption of normal body flora, and possibly increased resistance to antibiotics.
