The UroCuff Test

The UroCuff TestThe UroCuff test is a modern-day solution to previously invasive Urodynamic testing. The goal of UroCuff (and previously Urodynamics) is to assess overall bladder efficiency by determining bladder function, capacity, pressure, and urine flow.

It is used to help counsel patients about the likelihood of bladder outlet obstruction from an enlarged prostate. In patients with BPH, the UroCuff test will usually show a low urine flow and higher than normal bladder pressures.

How does it work?

The UroCuff Test measures the amount of urine expelled during a void, the rate at which its expelled, and the amount of pressure generated by the bladder during urination. Patients should come to clinic with a full bladder after drinking about 32 ounces of water one hour prior to the scheduled test.

To begin, a pneumatic cuff is fitted to the penis. Once the cuff is in place, the patient is instructed to void into a flow meter. During the void, the cuff inflates until urine flow is interrupted. The cuff then rapidly deflates, allowing urine flow to resume. This cycle repeats until the patient is empty. Bladder function is determined by observing the relationship between interruption bladder pressure vs. flow rate.

Is UroCuff testing painful?

No. The test takes about 5 minutes and there are no significant side effects noted.

The advantage of the UroCuff test compared to urodynamics is that painful and invasive urinary and rectal catheters are not needed to determine the answer to the same important question: is the patient showing signs of an obstructed prostate with deteriorating bladder health?

HTX Urology offers UroCuff testing for all male patients that experience changes in their bladder health, including weak stream, urinary urgency / frequency, and increased nighttime urination. An abnormality in UroCuff testing will help identify patients that will benefit from BPH treatment, such as UroLift or TURP, to preserve bladder function long-term. A UroCuff test can also be performed after prostate surgery to monitor bladder efficiency before and after intervention.
