• Conditions: Ureterocele; Urinary Calculi
• Interventions: Device: Use of shuotong ureteroscopy

• Registration Number: NCT05712785
• Lead Sponsor: Handan First Hospital

Brief Summary

The purpose of this study is to use the Shuotong ureteroscopy for surgical treatment of patients with upper urinary tract stones, taking advantage of the fact that the Shuotong mirror can be used for simultaneous lithotripsy and stone removal, thus maximizing the discharge of stones from the body and improving the stone removal rate.

Detailed Description

Ureteroscopy via the natural lumen has the advantages of being non-invasive, safe and repeatable. This is where Shuotongo ureteroscopy, a new type of ureteroscopy, has not yet become fully popular. Usually, most patients with upper urinary tract stones are treated by ureteroscopy or with flexible ureteroscopy, because these endoscopes usually break the stones and ask the patient to drink more water to expel the stones by themselves, after the operation, it is usually easy to leave stones in the body, and some patients even form stone streets to block the ureter again after the operation. In some patients, stones may form again and obstruct the ureter again. The Shuotong Ureteroscopy has the advantages of stone crushing and stone removal, which can synchronize the process of stone crushing and stone removal and maintain a good surgical view. It has the advantages of simple operation, less trauma and high safety for the operation via natural channel, especially for the large stones in the upper urinary tract and Gantun stones.
