Outcomes of Using FANS With FURS in TTT of Lower Calyceal Stones. 33

Recruiting
Clinical Trial NCT07238803 is an interventional study for Kidney Stone, Kidney Calculi that is recruiting. It started on 1 December 2024 with plans to enroll 33 participants. Led by Zagazig University, it is expected to complete by 1 February 2026. The latest data from ClinicalTrials.gov was last updated on 20 November 2025.
Brief Summary
The aim of this study is to evaluate and assess the outcomes of flexible ureteroscopy (FURS) with flexible and navigable suction UAS (FANS) in the treatment of lower calyceal stones.
Detailed Description
With the continued advancements of technology and increasing experience gained by urologists in ureteroscopic skills, fURS has become a standard treatment for kidney stones lesser than 2 cm in diameter. In the previous the European guidelines and American Urologic Association guidelines for management of urolithiasis, fURS were recommended as a second-line treatment for stones less than 2 cm after ESWL, however in th...Show More

Patients with lower calyceal stones
flexible and navigable suction sheath with flexible ureteroscopy
placement of flexible and navigable suction sheath (FANS)which has an oblique side branch with pressure vent, that can be connected to negative pressure aspiration, and a flexible tip, allowing for efficient and effective treatment of urinary stones. * Flexible URS diameter will be at the least 2 Fr smaller than the sheath. * The main tube is closed by a rubber seal with a center aperture as the flexible ureteroscop...Show More
Primary Outcome Measures
Outcome MeasureMeasure DescriptionTime Frame
Evaluation of Stone-Free Rate Following Flexible Ureteroscopy with FANS sheath for Management of Renal and Ureteral Calculi.
This clinical study aims to evaluate the stone-free rate (SFR) following flexible ureteroscopy (FURS) in patients with renal or ureteral calculi. The primary outcome measure is the proportion of patients who achieve complete stone clearance, as determined by postoperative imaging (non-contrast CT or ultrasound) within a defined follow-up period.
1 month after the procedure (preferred and most common for SFR assessment)
