Memokath - Model 051 Ureter - Non-Allergenic Metallic Stent

SHARE

Memokath™ 051 Ureter is a NICE-recommended non-allergenic metallic stent used to effectively treat ureteric stricture without the side-effects of major surgery, or discomfort of catheters. Memokath™ 051 Ureter is a non-allergenic metallic stent used to effectively treat ureteric stricture. The stent is typically inserted in 30-45 minutes under general or spinal anesthesia and can be inserted either retrograde or antegrade to be positioned across the stricture allowing urine to flow through the ureter. Memokath™ 051 Ureter provides urinary flow without the side-effects of major surgery and discomfort of catheters. It can remain inside the body for several years before needing replacement, in contrast to JJ-catheters needing 4-6 changes per year.

Memokath™ 051 Ureter 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.
