Ureteral Access Sheath Deployment: Understanding the Force Tolerance of the Human Ureter and the Development of Ureteral Injury During Endoscopic Surgery
Adherence to a force threshold of ≤6 N during UAS passage resulted in safe passage of a 16F UAS in 58% of 250 renal units; when adhering to the recommended ≤6 N force threshold, there were no PULS 3 injuries. A preexisting indwelling ureteral stent and administration of antibiotics within 6 weeks of the procedure independently favored safe passage of a 16F UAS.
