Aims: The aim of this study was to compare magnetic resonance imaging (MRI) parameters in patients with mild incontinence after radical prostatectomy, who had undergone treatment with a suburethral sling. The objective was to compare patients who had been successfully treated with unsuccessful patients., Methods: This observational cohort study at a single institution evaluated consecutive patients treated with an AdVance XP sling. MRI was performed using a 1.5 Tesla system. Preoperative urodynamic assessment and flexible cystoscopy were performed. The qualitative analysis was based on sling indentation (complete vs incomplete). The quantitative analysis comprised the following three parameters: the sling-pubis distance, the thickness of the proximal urethral bulb, and the sling backward distance (SBD), defined as the distance between the prolongation of a line through the major axis of the pubis (the line-segment joining the vertices of the pubis) and the sling indentation. The primary outcome was pad count at 3 months; cure as zero pads. A logistic univariate regression model was employed to assess the potential predictors of successful outcomes. An adjusted multivariate logistic regression model using the significant univariate factors was developed., Results: Of the 83 patients enrolled, the univariate analysis revealed a relationship between failure and adverse urodynamics and between success and sling indentation, thickness of the proximal bulb and SBD. Only the association with SBD persisted in the multivariate analysis., Conclusions: MRI revealed a strong relationship between proper positioning of the sling (small SBD) and continence outcome. These data have important implications for a second surgery following initial sling failure., (© 2019 Wiley Periodicals, Inc.)

Objectives: To validate the relation of the nephrometry scores in a series of patients who underwent partial nephrectomy with perioperative parameters and the urologist-radiologist reproducibility., Material and Methods: A retrospective study of open and laparoscopic partial nephrectomy patients performed between 2005 and 2012 registered in prospective filled out database. An urologist and a radiologist calculated the R.E.N.A.L., PADUA and C-index for 86 patients. We carried out a comparative study of the results using the Spearman and Pearson correlation indexes., Results: Distribution according to the complexity of the tumors with the RENAL calculation was: 42 (49%) low, 35 (41%) moderated and 9 (11%) high complexity. According to PADUA: 35 (41%) low complexity, 32 (37%) intermediate and 19 (22%) high. No statistically significant correlation was found for the appearance of operative complications and the pathology results in case of RENAL and PADUA. A correlation was found in the case of PADUA in relation to the warm ischemia time. Positive correlation according to Spearman's index was found in RENAL, PADUA and C-index between urologist and radiologist evaluations., Conclusions: Nephrometry scores can be a useful tool to plan the surgical technique or approach. However, it is not clear if they are really predictors of surgical or pathologic parameters. The correlation between the urologist and radiologist seems to be sufficient to recommend their use by both specialties., (Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.)
