Table 3 Intra- and interrater reliability with 95% confidence interval (CI) for the measurement 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
