@itchybits - I also found - along the same lines as I think a bidet works with the water stream - that using a squeeze bottle occasionally after urinating clears the area.

I was given one after my last 2 procedures, and even had to carry it with me (already filled with water), along with other supplies like Vaseline, when I was getting back to normal and - slowly! - healing over those 7 weeks of excruciating urinating due to the laser ablation.

So, though it's not so practical to carry one along outside the home, I use it occasionally at home just for a sense of general cleansing, beyond the TP.
