Ha HK, et al. - Through a retrospective comparative measurement of pre- and postoperative magnetic resonance imaging scans of 20 Korean patients with median prostate volume 27.5 mL and maximum volume 70 mL, the researchers described three novel methods used for the measurement of the displacement of the vesicourethral junction (VUJ), proximal membranous urethra (PMU) and anorectal junction (ARJ); and the VUJ angle of displacement in men following radical prostatectomy and ascertained their intra- and interrater authenticity. Less reliability and more variability were offered by other measurement systems. For the measurement of the displacement of the VUJ and PMU and the VUJ angle of displacement, good to excellent reliability and the lowest variability was demonstrated through pubococcygeal line measurement methodology. Hence, it should be the method of choice. Validation of this methodology in patients with large prostate volumes is recommended.
