NCT ID NCT05779943

First seen Oct 31, 2025 · Last updated May 05, 2026 · Updated 18 times

Summary

This study tests whether adding furosemide (a diuretic or "water pill") to a special PET/CT scan can reduce bladder radioactivity and improve detection of recurrent prostate cancer in 20 men whose PSA levels rose after prostate removal. Participants receive two scans—one with and one without furosemide—to compare bladder activity. The goal is to see if this simple addition helps doctors spot hidden cancer more clearly.
