Impact of urine culture timing on outcomes after kidney stone surgery
The Effect of Preoperative Culture Timing on Postoperative Outcomes of Retrograde Intrarenal Surgery
This study looks at whether taking urine samples two weeks before kidney stone surgery helps prevent infections better than taking them closer to the surgery date.

What this trial studies
This observational study investigates the timing of urine culture collection prior to retrograde intrarenal surgery (RIRC) and its effect on postoperative outcomes, particularly the rate of infections. It aims to determine the optimal timing for urine cultures to ensure they are sterile before surgery, as infections can lead to severe complications. The study compares urine cultures taken two weeks before surgery with those taken closer to the operation date to assess the risk of postoperative infections.
Who should consider this trial
Good fit: Ideal candidates for this study are adults over 18 years old who have a sterile urine culture taken two weeks prior to their scheduled retrograde intrarenal surgery.
Not a fit: Patients under 18 years of age, those with positive urine cultures, or individuals with renal anomalies or a solitary kidney may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved guidelines for urine culture timing, reducing the risk of postoperative infections and complications for patients undergoing kidney stone surgery.
How similar studies have performed: While there are guidelines regarding urine culture timing, this specific approach to determining the optimal timing has not been extensively tested in prior studies.
