    Abstract Knowledge about anatomical details seems to facilitate the procedure and planning of prostatic artery embolization (PAE) in patients with symptomatic benign prostatic hyperplasia (BPS). The aim of our study was the pre-interventional visualization of the prostatic artery (PA) with MRA and the correlation of iliac elongation and bifurcation angles with technical success of PAE and technical parameters. MRA data of patients with PAE were analysed retrospectively regarding PA visibility, PA type, vessel elongation, and defined angles were correlated with intervention time, fluoroscopy time, dose area product (DAP), cumulative air kerma (CAK), contrast media (CM) dose and technical success of embolization. T-test, ANOVA, Pearson correlation, and Kruskal-Wallis test was applied for statistical analysis. Between April 2018 and March 2021, a total of 78 patients were included. MRA identified the PA origin in 126 of 147 cases (accuracy 86%). Vessel elongation affected time for catheterization of right PA (p = 0.02), fluoroscopy time (p = 0.05), and CM dose (p = 0.02) significantly. Moderate correlation was observed for iliac bifurcation angles with DAP (r = 0.30 left; r = 0.34 right; p = 0.01) and CAK (r = 0.32 left; r = 0.36 right; p = 0.01) on both sides. Comparing the first half and second half of patients, median intervention time (125 vs. 105 min.) and number of iliac CBCT could be reduced (p < 0.001). We conclude that MRA could depict exact pelvic artery configuration, identify PA origin, and might obviate iliac CBCT. Vessel elongation of pelvic arteries increased intervention time and contrast media dose while the PA origin had no significant influence on intervention time and/or technical success.

    Abstract Background: To investigate the influence of benign prostatic hyperplasia (BPH) patterns detected with MRI on clinical outcomes after prostatic artery embolization (PAE).
    Materials & methods: This retrospective study included 71 consecutive patients with lower urinary tract symptoms (LUTS), who underwent magnetic resonance imaging (MRI) of the prostate followed by PAE at a single centre. MRI scans were evaluated and BPH patterns were determined according to Wasserman type and a modified BPH classification. Additionally, scans were evaluated regarding the presence of adenomatous-dominant benign prostatic hyperplasia (AdBPH). LUTS were assessed using the International Prostate Symptom Score (IPSS) and urinary flow rate (Qmax). Follow-up examination included MRI and clinical outcome.
    Results: For clinical outcome at follow-up, IPSS showed median reduction of 54% (IQR 41-75%) and Qmax improved by 4.1 ml/s. We noted significant reduction in volume, intraprostatic protrusion, and prostatic urethral angle in our collective (p < 0.01). Median volume reduction was 25% (IQR 15%-34%). Bilateral embolization was a significant predictor for volume reduction at follow-up. Multiple linear regression analysis showed significant effect of high initial volume on reduction in IPSS after treatment (p < 0.01). Presence of AdBPH was significantly associated with both, volume loss and clinical improvement in terms of IPSS reduction (p < 0.01). Neither BPH pattern based on the Wassermann type nor modified BPH classification were significantly related with postinterventional IPSS and volume loss.
    Conclusions: Men benefit from PAE regardless the macroscopic BPH MRI pattern. Preinterventional prostate volume and presence of AdBPH on MRI should be considered for outcome prognosis after PAE.

    Abstract Background: Data on oncological follow-up after robotic-assisted radical cystectomy (RARC) have been reported only scarcely and individual studies have reported an increase in early recurrences and atypical recurrences.
    Patients and methods: Clinical data of 89 patients with RARC were compared to 59 patients with open radical cystectomy (ORC) at a single institution. Two-year cancer-specific (2y-CSS) and 2-year overall survival (2y-OS) related to histopathological tumor stage of RARC patients calculated by Kaplan-Meier method were compared to ORC patients using log-rank test. Early clinical recurrence rate (eCR, progression ≤6 months post-cystectomy) and metastatic pattern of both groups were compared by chi-square test.
    Results: Median follow-up 32 months (RARC) and 47.5 months (ORC), both groups were balanced in baseline characteristics. For RARC pts, -2y-OS and CSS-free survival rates were 80 and 90%, for ORC pts 65 and 71% (all p > 0.05). Margin status was not significantly different. eCR was observed in 10 out of 89 (11%) RARC pts and in 7 out of 59 (12%) ORC pts (p = 0.9). No difference in atypical metastases was seen between groups.
    Conclusion: Two-year oncological outcomes of RARC patients are comparable to ORC patients without differences regarding ePR or metastatic pattern.

    Abstract Despite the introduction of arterial stiffness measurements in the European recommendation, pulse wave velocity (PWV) and augmentation index (AI) are still not used routinely in clinical practice. It would be of advantage if such measurements were done in the sitting position as is done for blood pressure. The aim of this study was to evaluate whether there is a difference in stiffness parameters in sitting vs. supine position. Arterial stiffness was measured in 24 healthy volunteers and 20 patients with cardiovascular disease using three different devices: SphygmoCor (Atcor Medical, Sydney, Australia), Arteriograph (TensioMed, Budapest, Hungary) and Vascular Explorer (Enverdis, Jena, Germany). Three measurements were performed in supine position followed by three measurements in sitting position. Methods were compared using correlation and Bland-Altman analysis. There was a significant correlation between PWV in supine and sitting position (Arteriograph: P<0.0001, r=0.93; Vascular Explorer; P<0.0001, r=0.87). There were significant correlations between AI sitting and AI supine using Arteriograph (P<0.0001, r=0.97), Vascular Explorer (P<0.0001, r=0.98) and SphygmoCor (P<0.0001, r=0.96). When analyzed by Bland-Altman, PWV and AI measurements in supine vs. sitting showed good agreement. There was no significant difference in PWV obtained with the three different devices (Arteriograph 7.5±1.6 m s(-1), Vascular Explorer 7.3±0.9 m s(-1), SphygmoCor 7.0±1.8 m s(-1)). AI was significantly higher using the Arteriograph (17.6±15.0%) than Vascular Explorer and SphygmoCor (10.2±15.1% and 10.3±18.1%, respectively). The close agreement between sitting and supine measurements suggests that both PWV and AI can be reliably measured in the sitting position.
