Full of potential.
This article reviews the novel Nasser-Zelefsky catheter designed to maintain consistent bladder filling during radiation treatments. It consists of two balloons, the lower filled with water serving as an anchor at the bladder neck and the upper connected by a string and filled with air floating on collected urine. The air-filled balloon is the novel part and opens a valve to release urine once tension is established on the string, meaning string length determines amount of filling. Just check out figures 1-2. The downside is it’s an in-dwelling catheter for the duration of treatment with the filling mechanism activated by the patient 2-3 hours prior to treatment. TBL: Clinical investigations into the safety, feasibility, and utility of the Nasser-Zelefsky catheter will soon be underway. | Nasser, tipsRO 2021
