Endorsing the principles of minimal invasiveness in benign-prostatic hyperplasia (BPH) surgery, we conducted the first evaluation of transurethral intraprostatic anesthesia (TUIA) using Schelin catheter® (SC) prior to iTIND positioning.

Of 23 patients enrolled, 11 (48%) received TUIA via SC whereas the remaining underwent standard anesthesia protocol. Pain was assessed using visual analogue scale (VAS).

No differences between cohorts were observed for pain during the device implantation and removal. Conversely, significantly lower median VAS scores were reported at 24- (1.0 vs. 3.0) and 48- (1.0 vs. 2.5) hour follow-up favoring TUIA.

SC TUIA offers effective pain control during iTIND procedures, supporting its use in outpatient settings.
