A surgical system adapted for dissection of tissue away from a body lumen includes a tissue dissection tool and a catheter. The tissue dissection tool includes a shaft connected between a handle and a tissue dissection head. At least the tissue dissection head of the tissue dissection tool is magnetized to a first polarity. The catheter is insertable into a urethra, with a wall of the catheter magnetized to the first polarity. When the catheter is inserted into the urethra, the first polarity of the catheter is configured to repel the first polarity of the tissue dissection head of the tool away from the catheter and away from in the urethra.
