Table 4 Mean ± SD of the differences between and within raters for the measures of displacement of the VUJ, PMU and ARJ (mm) and the VUJ angle of displacement (degrees)

From: Three novel methods to measure the postoperative displacement of lower urinary tract structures following radical prostatectomy in a sample of Korean patients
