Spanner - Prostatic Stent
The Spanner® Prostatic Stent is a temporary stent inserted into the urethra at the neck of the bladder to maintain urine flow. The Spanner benefits men with bladder outlet obstruction (BOO) by reducing elevated post void residual (PVR), improving voiding symptoms, and allowing for voluntary urination. As an alternative to a Foley catheter, it allows men to naturally fill and empty their bladders. Urologists and patients agree that The Spanner makes a difference in clinical outcomes and daily living.

The Spanner Prostatic Stent is a temporary stent inserted into the urethra at the neck of the bladder to maintain urine flow. The Spanner benefits men with bladder outlet obstruction (BOO) by reducing elevated post void residual (PVR), improving voiding symptoms, and allowing for voluntary urination. As an alternative to a Foley Catheter, it allows your patients to naturally fill and empty their bladders.
Key Benefits of The Spanner
- Clinically proven to accurately measure voiding pressure.
- Normal micturition achieved with bladder and sphincter.
- Simple and quick to perform.
- Improves urination efficiency by decreasing urine left in the bladder.
- Reduces rate of bacterial colonization compared to the Foley catheter.
- Well tolerated by patients.
- Improves IPSS scores.
- Greatly preferred by patients over catheterization.
How It Works
The Spanner® Prostatic Stent has been designed to open the prostatic urethra and allow patients to maintain urine flow and allow volitional voiding by reducing urethral resistance within the prostate. As shown in the figure to the left The Spanner has a proximal balloon that is seated in the bladder neck to properly position the stent in the prostatic urethra. The stent extends from the bladder to just above the external sphincter. Device tethers (suture material) traverse the external sphincter to allow normal sphincter function, thus providing patients the ability to volitionally void. The distal anchor of the device is positioned in the bulbar urethra, just below the sphincter, to prevent device movement and migration into the bladder.
The Spanner Placement
The Spanner is inserted and positioned tactilely using a detachable introducer (no cystoscopy required). The Spanner has been designed for administration in the office setting with use of a numbing agent for patient comfort.
The Spanner Removal
The stent is removed using the retrieval tether (retrieval suture) that provides for the deflation of the balloon and withdrawal of the stent.
How The Spanner Is Provided
The stent and introducer are provided together in a sterile package. The Spanner is currently available in 20F diameter, six sizes (4, 5, 6, 7, 8 and 9 cm) with a coude-tip. The Spanner size selection is enabled by the use of an accessory, The Surveyor™ urethral measurement device. The Surveyor is designed to assess the length of the urethra from the bladder neck to the bottom side of the external sphincter in order to select the appropriate Spanner size.

What is The Spanner Stent and what is it used for?
The Spanner is a medical device called a temporary stent which resides completely within your body. The Spanner stent allows some men who can’t empty their bladder to urinate naturally without the need for a Foley catheter and an external leg bag. With The Spanner in place, you will maintain full control over urination—starting and stopping as you wish. Your urine will flow through The Spanner tube and out of your body.
Cross-sectional view of The Spanner
The Spanner has a small balloon near the tip which stays inside the bladder. This balloon is used to keep The Spanner in place. The tube allows urine to flow from the bladder through the portion of the urethra that the enlarged prostate gland is blocking. It holds the urethra open even though the prostate is pressing on it. The tube does not go through the sphincter, because if it did you would not be able to stop your urine from draining from your bladder. This is called incontinence or the accidental loss of urine. There are soft strings that do go through the sphincter, but they will not affect urination or cause accidental loss of urine. A soft tab connected to the strings is located at the other end of the stent. This tab keeps the stent from moving into the bladder. A retrieval string is tied to The Spanner, and is used to drain the balloon when it is time to remove The Spanner.
