Summary

This study looked at 96 men who needed a temporary tube (stent) in their ureter after kidney stone surgery. Half got a standard stent, the other half got a new anti-reflux stent. Researchers checked sexual function, mood, and hormone levels over 8 weeks to see if the anti-reflux design causes fewer sexual side effects.
