Artificial urethral sphincter

Case contributed by Dr Chris O'Donnell


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

Patient Data

Age: 75 years
Gender: Male

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


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 sphincter is detected.
