BLOOMINGTON, Ind.--(BUSINESS WIRE)--A recent study by Breda et al shows that the Flexor® Parallel™ Rapid Release™ Ureteral Access Sheath (UAS) provides physicians an option to use one wire guide for treatment and diagnostic purposes during flexible ureteroscopy (fURS) procedures. The study confirmed that when the Flexor® Parallel™ is used for fURS procedures, a single wire guide can serve as both the safety and working wire.1
