Abstract

Purpose of Review

Herein we report a systematic review of literature to identify the contemporary focus areas of magnetic resonance imaging (MRI) use in benign Urology and present the highest yield results.

Recent Findings

MRI, specifically upright MRI, in combination with proper instructions and repeated Valsalva maneuvers, allows for more objective assessment of pelvic organ prolapse (POP) staging. The lack of standardization of reference lines and points used in MRI evaluation of POP is a key limitation. Evaluation of prostate artery embolization (PAE) as an effective treatment for benign prostatic hyperplasia (BPH) was a key focus of recent studies, but clear data regarding ideal patient population, procedure standardization, and performance compared to TURP are still lacking. A longer membranous urethral length (MUL) measured on MRI was predictive of post-prostatectomy continence. Dynamic MRI of the vesicourethral junction provided insight into the development of stress urinary incontinence (SUI) and the factors that contribute to successful treatment with a sling. Functional MRI demonstrated that localization of the defective signaling mechanism in women with overactive bladder (OAB) determines their likelihood to respond to pelvic floor muscle training. Patients with both neurogenic and non-neurogenic LUT dysfunction show abnormalities in both grey and white brain matter compared to healthy individuals, especially in the pontine micturition center and periaqueductal grey.

Summary

MRI has become an indispensable tool in benign Urology with its applicability in diagnosis, prediction, and prognosis of the disease at the organ level (bladder, prostate, urethra) and beyond (brain).

Adjuvante Immuntherapie verlängert Leben bei RCC

25.04.2024 Nierenkarzinom Nachrichten

Nun gibt es auch Resultate zum Gesamtüberleben: Eine adjuvante Pembrolizumab-Therapie konnte in einer Phase-3-Studie das Leben von Menschen mit Nierenzellkarzinom deutlich verlängern. Die Sterberate war im Vergleich zu Placebo um 38% geringer.

Bei Senioren mit Prostatakarzinom auf Anämie achten!

24.04.2024 DGIM 2024 Nachrichten

Patienten, die zur Behandlung ihres Prostatakarzinoms eine Androgendeprivationstherapie erhalten, entwickeln nicht selten eine Anämie. Wer ältere Patienten internistisch mitbetreut, sollte auf diese Nebenwirkung achten.

Stufenschema weist Prostatakarzinom zuverlässig nach

22.04.2024 Prostatakarzinom Nachrichten

Erst PSA-Test, dann Kallikrein-Score, schließlich MRT und Biopsie – ein vierstufiges Screening-Schema kann die Zahl der unnötigen Prostatabiopsien erheblich reduzieren: Die Hälfte der Männer, die in einer finnischen Studie eine Biopsie benötigten, hatte einen hochgradigen Tumor.

Harnwegsinfektprophylaxe: Es geht auch ohne Antibiotika

20.04.2024 EAU 2024 Kongressbericht

Beim chronischen Harnwegsinfekt bei Frauen wird bisher meist eine Antibiotikaprophylaxe eingesetzt. Angesichts der zunehmenden Antibiotikaresistenz erweist sich das Antiseptikum Methenamin-Hippurat als vielversprechende Alternative, so die Auswertung einer randomisierten kontrollierten Studie.
