Abstract
Description
Die Erfindung betrifft einen Kathetersystem zur Behandlung der benignen Prostatahypertrophie oder -hyperplasie.The The invention relates to a catheter system for the treatment of benign Prostate hypertrophy or hyperplasia.
Die benigne Prostatahypertrophie oder -hyperplasie ist die häufigste Ursache von Blasenentleerungsstörungen (BPH) bei Männern. Der langsame und schubweise Verlauf führt zu verzögertem Harnlassen, einer allmählichen Abschwächung des Harnstrahls und kann in einem weit fortgeschrittenen Stadium zur Hydronephrose und einer progredienten Niereninsuffizienz führen.The Benign prostatic hypertrophy or hyperplasia is the most common Cause of bladder voiding disorders (BPH) in men. The slow and bumpy course leads to delayed Urination, a gradual weakening of the Urinary stream and can be at a very advanced stage for Hydronephrosis and progressive renal failure.
Die Linderung der Symptomatik wird beispielsweise durch 5α-Reduktasehemmer und Alpha-1-Rezeptorenblocker erreicht. Ansonsten erfolgt operative Entfernung eines Teils der Prostata, beispielsweise durch Lasertherapie unter sonografischer oder endoskopischer Kontrolle, Kryochirurgie oder bevorzugt durch transurethrale Resektion.The Alleviation of the symptoms is achieved, for example, by 5α-reductase inhibitors and alpha-1 receptor blocker achieved. Otherwise, operational Removal of part of the prostate, for example by laser therapy under sonographic or endoscopic control, cryosurgery or preferred by transurethral resection.
Im einfachsten Fall erfolgt die transurethrale Resektion (TUR) durch eine durch die Harnröhre eingeführte elektrische Schlinge, mit der ein Teilbereich der Prostata lokal auf eine durch den elektrischen Strom bedingte hohe Temperatur erwärmt wird, bei der die Prostatazellen absterben und die Prostata somit insgesamt verkleinert wird.in the The simplest case is transurethral resection (TUR) an inserted through the urethra electrical Noose, with a portion of the prostate gland locally on one the electric current caused high temperature heated becomes, with which the Prostatazellen die off and the Prostata thus total is reduced.

Diese Art Katheter besitzt jedoch den Nachteil, dass der Einstich der Nadel zu einer schmerzhaften Verletzung führt, die das erhöhte Risiko einer möglichen Infektion nach sich zieht. Außerdem wirken diese Nadeln lokal sehr begrenzt und führen möglicherweise zu einer ungenügenden, weil nur einen begrenzten Teilbereich betreffenden Ablation hypertrophen Gewebes.These However, Art catheter has the disadvantage that the puncture of Needle leads to a painful injury that the increased risk of a possible infection pulls. In addition, these needles are locally very limited and may lead to an insufficient, because only a limited portion of ablation hypertrophy Tissue.
Aufgabe der Erfindung ist es daher ein Kathetersystem zur Behandlung der benignen Prostatahypertrophie oder -hyperplasie bereitzustellen, der ein schonendes und gleichmäßiges Ablationsverfahren einer hypertrophen oder hyperplastischen Prostata ermöglicht.task Therefore, the invention is a catheter system for the treatment of to provide benign prostatic hypertrophy or hyperplasia; the gentle and uniform ablation procedure a hypertrophic or hyperplastic prostate.
Die Erfindung wird durch ein Kathetersystem mit den in Anspruch 1 genannten Merkmalen gelöst. Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.The The invention is characterized by a catheter system with the recited in claim 1 Characteristics solved. The dependent claims give advantageous Embodiments of the invention again.
