[Can high-frequency currents in transurethral resections lead to urethral strictures?].
During transurethral resections measurements of the high-frequency tension yielded on the shaft only 8-10% of the tension at the loop. At the beginning of every operation the tension at that loop was measured where first tissue reactions appeared. It is approximately 24 V during cutting. By means of the estimation of the field intensity by simultaneous measurement of the tension in the symphyseal area and by theoretical estimation of the field intensity is shown that, when properly used, a damage by the high-frequency current cannot appear.
