ProstaMetrix is a medical device that accurately and repeatably measures prostate volume, a key variable that helps clinicians diagnosis prostate cancer. ProstaMetrix consists of a controller device connected to an encoder device.


The encoder is placed over the clinicians finger and used to measure the width of the patient’s prostate during a procedure that is similar to a digital rectal exam (DRE). The controller uses the width measurement to calculate the volume of the prostate in cubic centimeters (cc).

When combined with PSA test results, prostate volume helps clinicians better distinguish between low-risk versus higher-risk incidents of prostate cancer. As a result, clinicians can improve their diagnostic test and treatment decisions, thereby minimizing negative patient outcomes and avoiding unnecessary costs.


Prostate volume also helps clinicians understand and treat certain urinary problems caused by an enlarged prostate (BPH).
