Memokath™ 045 Urethra

Memokath™ 045 Urethra is a non-allergenic metallic stent used to effectively treat penile urethral stricture without the side-effects of major surgery, or discomfort of catheters.

Brief introduction

Memokath™ 045 Urethra is a non-allergenic metallic stent used to effectively treat penile urethral stricture. The stent is typically inserted in 30-45 minutes under local anesthesia through the urethra with a cystoscope and positioned across the stricture to allow urine to flow through the urethra. Memokath™ 045 Urethra preserves normal bladder control and provides urinary flow without the side-effects of major surgery and discomfort of catheters. It can remain inside the body for up two years or more before needing replacement.

The effectiveness and long-term patency of Memokath™ 045 Urethra also makes it viable solution for patients who receive incisions or dilatations regularly, as well as for patients of high age, frailty, or on anticoagulant medicine.

Side effects and complications

Memokath™ 045 Urethra generally causes few and only minor side-effects. Blood may occur in the patients’ urine for a period after the insertion, which is normal. The risk of complications is also minor and pertains to migration or encrustation of the stent. If the stent migrates, it can often be repositioned. If not, it can simply be removed or exchanged with a new stent. If the stent encrusts it will typically have to be exchanged. Vigilance by both patients and doctors towards reoccurring symptoms is always recommended to avoid complete encrustation.

Living with Memokath™ 045 Urethra

Memokath™ 045 Urethra typically offers patients a quick return to daily activities after treatment, most often with a substantial decrease in symptoms, and little or no side-effects or complications. Instructing the patients to drink plenty of water will help minimize risk of encrustation. Patient-checkups are advised to ensure the stent continue to function optimally.

What treatments should Memokath™ 045 Urethra be considered before?

Memokath™ 045 Urethra should be presented to all relevant patients as part of the treatment options for penile urethral obstruction. MemokathTM 045 Urethra has in many cases improved the quality of life substantially for patients living with catheters or receiving regular incisions or dilatations and would have been a preferred option for many patients who have been treated through surgery, and now suffer from debilitating side-effects and complications. Consider treatment with Memokath™ 045 Urethra before:

  • Foley catheters
  • Clean intermittent self-catherization (CISC)
  • Repeated incisions
  • Repeated dilations
  • Urethroplasty

Case examples

  • Unsuccessful repeated incisions

    Hesitant to undergo surgery or become dependent on catheters a 58-year old male is treated periodically with urethrotomies for his urethral stricture, with the stricture recurring a few months after every time. Memokath™ 045 Urethra now treats his symptoms with much less frequent treatments and much higher quality of life.

  • Weary from self-catheterization

    An untreated sexual transmitted disease caused a penile urethral stricture for a 53-year old. Unwilling to undergo surgery, he has been dependent on self-catheterizing for more than three years but is disheartened and weary from use. After successful insertion of Memokath™ 045 Urethra the patient feels his quality of life lifted materially.

  • Unwilling to undergo urethroplasty

    Determined to avoid the risk of impotence and chordee as possible side-effects of urethroplasty as well as a lifetime of catheter-use a 39-year old male was offered the option of having a Memokath™ 045 Urethra inserted as treatment for a traumatic penile stricture. Memokath™ became the right choice for him and sits up to two years at the time.

  • Illness from Foley catheter-use

    After two years of unsuccessful self-catherization, and six months of Foley-catheter use a 78-year old is faced with continuous fever outbreaks and cloudy, pus-filled urine. Unable to undergo surgery due to frailty, Memokath™ 045 Urethra relieved the patient of infections and the materially decreased quality of life from catheterization.

  • Unsuccessful urethroplasty

    A traffic accident left a 35-year old with complete posterior urethral rupture. Two endoscopic urethroplasties are attempted, but no spontaneous voiding was achieved. Immediately after insertion of Memokath™ 044 Urethra the patient regained his ability to void spontaneously, and still does so two years after.
