Artificial Urinary Sphincter (AUS) Implantation

Artificial Urinary Sphincter (AUS) Implantation is a surgical procedure used to treat male urinary incontinence, particularly stress urinary incontinence (SUI), which can result from various conditions, such as prostate cancer treatment (radical prostatectomy) or other pelvic surgeries. AUS is a device that mimics the function of the natural urinary sphincter, which controls the flow of urine from the bladder. The AUS is designed to help patients regain control over their urination.

Here's an overview of AUS Implantation:


  • Treatment for Male Urinary Incontinence: The primary purpose of AUS implantation is to treat male urinary incontinence, specifically SUI. SUI is characterized by the unintentional leakage of urine when physical activities, such as coughing, sneezing, laughing, or lifting, increase abdominal pressure.



  • AUS implantation is typically performed under general or regional anesthesia. It involves several key components, including:

                A cuff that is implanted around the urethra to control urine flow.

                A pressure-regulating balloon placed in the abdomen.

                A pump that is implanted in the scrotum or the labia, depending on the patient's anatomy.

  • The cuff around the urethra functions as an artificial sphincter, preventing the uncontrolled leakage of urine. The patient can manually operate the pump in the scrotum or labia to deflate the cuff, allowing urine to pass, and then inflate it to close the urethra for continence.

Recovery: Recovery after AUS implantation may require some time for the incisions to heal. Patients will typically undergo training to learn how to operate the AUS device correctly. It is crucial to follow the surgeon's post-operative instructions carefully.

Risks and Complications: Potential risks and complications of AUS implantation may include infection, erosion of the device through the skin, mechanical failure of the device, and changes in sensation in the genital area. It is essential to regularly check and maintain the AUS device to ensure its proper function.

AUS implantation can significantly improve the quality of life for men experiencing SUI. It provides a level of control over urinary function, allowing individuals to regain confidence and engage in normal activities without the fear of incontinence. However, the procedure should be discussed in detail with a urologist or specialist to assess its suitability for the specific condition, and patients should be fully informed about the potential risks and benefits before proceeding with the surgery.
