Zusammenfassung

Das Nierenbeckenkarzinom macht 5% aller Urothelkarzinome aus. Insbesondere invasive Tumoren sind häufig biologisch aggressiv und weisen eine hohe Metastasierungstendenz auf. Die Organerhaltung sollte imperativen Indikationen (Tumor in Einzelniere, bilaterale Tumoren, zu erwartende dialysepflichtige Niereninsuffizienz nach radikaler Operation und erhöhtes Operationsrisiko bei offenem chirurgischen Vorgehen) vorbehalten bleiben.

Technisch kommen die offene, ureterorenoskopische oder perkutan-endoskopische Tumorexzision als organerhaltende Therapieformen in Frage.

Wann immer möglich, ist die Nephroureterektomie mit Blasenmanschettenexzision anzustreben; diese stellt die Standardtherapie des Nierenbeckenkarzinoms dar.

Abstract

Transitional cell carcinoma of the renal pelvis is relatively uncommon, and only 5% of all urothelial carcinomas occur in the renal collecting system. Invasive tumors are often aggressive in their biological behavior and show a high tendency for systemic progression. Conservative therapy should only be considered an option in patients with imperative indications (solitary functioning kidney, bilateral tumor, renal insufficiency).

In some cases, organ-sparing techniques such as open resection or endourological treatment (percutaneous or by ureteroscopy) can be performed.

However, nephroureterectomy with excision of a bladder cuff is considered to be the standard treatment and should be performed whenever possible.
