Urine showdown: which sample best spots prostate cancer?

NCT ID NCT01441687

First seen Mar 24, 2026 · Last updated May 25, 2026 · Updated 10 times

Summary

This study compares two types of urine samples—expressed prostatic secretion (EPS) and post massage urine (PMU)—to see which one more accurately predicts whether a prostate biopsy will find cancer. About 243 men scheduled for a prostate biopsy will provide both samples. The goal is to find a simpler, less invasive way to detect prostate cancer.
