Artificial urethral sphincter

Case contributed by Dr Chris O'Donnell

Presentation

History of prostate cancer. Long standing urinary incontinence treated by artificial urethral sphincter.

Patient Data

Age: 75
Gender: Male
Modality: Ultrasound

Rounded, well-defined cystic "mass" in the RIF that persisits following micturition and is not associated with blood flow on colour Doppler (sitting anterior to the common femoral vessels)

Modality: CT

Hydrostatic sphincter (cuff) device encircling the proximal penile urethra with tubing passing into the right scrotum (with electronics) and a reservoir of fluid in the right groin (representing the cystic "mass").

Case Discussion

The fluid-filled reservoir of these devices can be confused with pathology as in this case where a cystic mass was of concern in the RIF on ultrasound examination.  Equally testicular US can be confusing when the device for activating the spincter is detected.
