Safe Passage of a 16 French Ureteral Access Sheath Presentation - Amanda McCormac

May 9, 2023

In this presentation, Amanda McCormac discusses a study that aimed to identify clinical factors associated with the safe deployment of a 16 French ureteral access sheath. The study used a novel UCI force-sensing device during ureteral access sheath insertion among 238 patients undergoing ureteroscopy. The results showed that safe passage of a 16 French access sheath is reproducibly achievable, especially in pre-stented patients who had bacteriuria or completed a course of preoperative antibiotics.

Amanda McCormac: Dear viewers, we sought to identify possible clinical factors that might be associated with the safe deployment of a 16 French ureteral access sheath. Among 238 patients undergoing ureteroscopy, a novel UCI force-sensing device was employed during ureteral access sheath insertion.

Beginning with the 16 French sheath, sheaths were downsized in 2 French increments if 6 Newtons was reached.

In 58% of patients, a 16 French access sheath was deployed without any splitting of the urothelium. Three factors favored safe passage of a 16 French access sheath: preoperative stenting, a history of bacteriuria, and preoperative antibiotics.

In conclusion, using a force sensor, safe passage of a 16 French access sheath is reproducibly achievable, especially in patients who are pre-stented, had bacteriuria, or completed a course of preoperative antibiotics. Thank you.
