This study investigates the effectiveness of different imaging techniques in detecting kidney obstructions and leftover stone fragments after surgery. The focus is on comparing renal CT scans with renal ultrasounds to see which method is more accurate in identifying these conditions. A CT scan is a detailed imaging procedure that uses X-rays to create pictures of the inside of the body, while an ultrasound uses sound waves to produce images of organs and structures inside the body.

Participants in the study will undergo both renal CT scans and renal ultrasounds. These procedures will help researchers determine the sensitivity, which is the ability to correctly identify those with the condition, and specificity, which is the ability to correctly identify those without the condition, of each imaging method. This comparison aims to find the most effective way to detect kidney issues after endoscopic urologic surgery, a minimally invasive procedure used to treat urinary tract problems.

• Who can participate: Eligibility criteria are not specified in the provided information.
• Study details: Participants will receive both a renal CT scan and a renal ultrasound to compare the effectiveness of these imaging methods. A CT scan uses X-rays for detailed images, while an ultrasound uses sound waves. These tests will help determine which method better detects kidney obstructions and residual stones.
