About this trial
The rate of complications (unexpected situations) after retrograde intrarenal surgery is reported to be 9-25%, and the majority of these are postoperative infections. Surgery must be performed under sterile (microbial-free) urine culture to prevent these complications. There are guideline recommendations regarding sterile urine culture reporting, but it is not clear how long in advance it should be taken. The possibility of the patient becoming infectious again during the period leading up to surgery is a condition that needs to be determined. Therefore, the culture taken before surgery should be compared with the urine culture result taken at the latest possible time before the operation.

Postoperative infection rates
Is there a difference in postoperative infectious complications between patients with two sterile preoperative urine cultures and patients with sterile cultures 2 weeks before the operation but positive urine cultures taken on the morning of the operation?
