To investigate the feasibility of urethral stump length and width measurements in recorded videos of robot assisted radical prostatectomy (RARP) procedures using the Kinovea software and to assess if these measurements could be used as predictors of postoperative urinary continence. METHODSː: 53 patients were selected from an institutional database of 1400 cases and included in the study. All videos were analysed using the computer software "Kinovea". All measurements were performed using the

inserted bladder catheter as a reference point. RESULTSː: The reference point (bladder catheter) was available in 33 out of 53 patients. The median SUL was significantly higher in the continent group (10,50 vs 12,94 mm, p= 0.018). The urethral width measurements did not show a difference between the groups. In order to validate the Kinovea software as an accurate tool for the measurement of the urethral stump length and width results were correlated with the MRI measurements of the urethra. CONCLUSIONSː: The results of this study showed a significantly longer median surgical urethral length in continent patients. This article is protected by copyright. All rights reserved.
