Comparing two types of ureteral access sheaths for treating kidney stones

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the effectiveness of a bendable suction ureteral access sheath compared to a conventional ureteral access sheath in managing renal stones through flexible ureteroscopy. The study focuses on patients diagnosed with radiologically confirmed renal stones, specifically those with stones sized between 5-20 mm. Participants will undergo treatment using either type of sheath to determine which approach yields better outcomes in terms of stone removal and patient safety. The trial aims to enhance the minimally invasive treatment options available for nephrolithiasis.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Diagnosis: Radiologically confirmed renal stones (e.g., CT, ultrasound, or X-ray).
* Stone size within a specific range (e.g., 5-20 mm).
* Indication for Treatment: patients indicated for flexible ureteroscopy due to renal stones.
* Anatomical Suitability: normal or mildly altered renal anatomy that allows safe use of the access sheath.
* Willingness to participate and provide written informed consent.

Exclusion Criteria:

* \- Medical Conditions: Active urinary tract infection (UTI) or sepsis. Coagulopathy or inability to discontinue anticoagulation therapy. Significant comorbidities (e.g., severe cardiopulmonary disease). Pregnancy: Pregnant or breastfeeding individuals.
* Anatomical or Surgical Factors:

Severe ureteral stricture or obstruction preventing sheath placement. Congenital abnormalities affecting the urinary tract. - Stone Factors: Stones larger than the sheath's operational limit (e.g., \>20 mm). Multiple stones in different calyces that cannot be accessed in one session.

\- Previous Treatment: Recent (\<6 weeks) or repeated interventions for the same stones (e.g., prior lithotripsy or ureteroscopy).
