Radical prostatectomy (RP) has heterogeneous effects on survival of patients with metastatic prostate cancer (mPCa). A reliable model to predict risk of cancer-specific mortality (CSM) and the potential benefit derived from RP is needed. Patients diagnosed with mPCa were identified using the Surveillance, Epidemiology, and End Results database (2004-2015) and categorized in RP versus nonlocal treatment (NLT). Based on the Fine and Gray competing risks model in 8,463 NLT patients, a nomogram was created to predict CSM in mPCa patients. Decision tree analysis was then utilized for patient stratification. https://www.selleckchem.com/products/msc2530818.html The effect of RP was evaluated among 3 different subgroups. A total of 8,863 patients were identified for analysis. Four hundred (4.5%) patients received RP. The 5-year cumulative incidence of CSM was 52.4% for the entire patients. Based on nomogram scores, patients were sorted into three risk groups using decision tree analysis. In the low- and intermediate-risk group, RP was found to be significantly correlated with a 21.7% risk reduction of 5-year CSM, and 25.0% risk reduction of 5-year CSM, respectively, whereas RP was not associated with CSM in high-risk group (hazard ratio =0.748, 95% confidence interval 0.485-1.150; P=0.190). We developed a novel nomogram and corresponding patient stratification predicting CSM in mPCa patients. A newly identified patient subgroup with low-, and intermediate-risk of CSM might benefit more from RP. These results should be further validated and improved by ongoing prospective trials.

The purpose was to assess the association between prostate infarction and prostate volume (PV) reduction after prostatic artery embolization (PAE) and define the best time point in detection of prostate infarction. Ten male beagles (3.5-6.4 years) with spontaneous benign prostatic hyperplasia (BPH) underwent PAE. Magnetic resonance image (MRI) was conducted immediately before and 1 week, 2 weeks and 1 month after PAE to document prostate infarcts and measure PV. The sum of infarct areas (SUMIA) was measured and calculated using OsiriX software. Spearman's rank correlation was used to estimate the relationship of PV reduction rate with infarction percentage and SUMIA reduction. In comparison with baseline data, significant PV reduction (P<0.001) occurred at 2 weeks and continued to decrease substantially (P=0.004) from 2 weeks to 1 month after PAE. In the same fashion, significant decrease in both SUMIA and infarction percentage was observed from 1 to 2 weeks (P=0.002), and subsequently to 1 month (P=0.039 and P=0.016, respectively). Spearman's rank correlation test demonstrated infarction percentage at 1 week had a stronger correlation (r=0.880, P=0.001) with PV reduction rate at 1 month than infarction percentage at 2 weeks (r=0.733, P=0.016). PV reduction rate had a significant correlation with decrease in SUMIA (r=0.854, P=0.002) at 1 month after PAE. One week after PAE is an ideal time point to evaluate prostate infarction. Prostate infarction percentage at 1 week is a good predictor for prostate shrinkage at 1 month after PAE. One week after PAE is an ideal time point to evaluate prostate infarction. Prostate infarction percentage at 1 week is a good predictor for prostate shrinkage at 1 month after PAE. Low-intensity extracorporeal shock wave therapy (Li-ESWT) is an effective therapy for erectile dysfunction (ED) but is not widely recognized and applied. This prospective nonrandomized study aimed to investigate the efficacy and safety of Li-ESWT. After a 4-week washout period of past ED treatment, patients entered one of 2 active treatment groups, either 9-week Li-ESWT or 100 mg on-demand sildenafil. Patients were evaluated in the first- and third-month following initiation of treatment. The Li-ESWT protocol comprised 2 sessions per week for 3 weeks, which were repeated after a 3-week interval. Patients in the drug group took self-administered sildenafil at a dose of 100 mg before intercourse. The primary outcome was the effectiveness of Li-ESWT measured by the International Index of Erectile Function-5 (IIEF-5) scores. Other measurements included erection hardness score (EHS) and Self-Esteem And Relationship (SEAR). A total of 78 participants completed the study (46 in the Li-ESWT group and 32 in the sildenafil group). Overall, 26.9% of the participants (21/78) included were psychogenic. In the third month, the outcome measured by IIEF-5 was 21.52 in the Li-ESWT group and 21.26 in the sildenafil group (P>0.05). Proportion of improvement defined by minimal clinically important difference (MCID) criteria was 52.2% in the Li-ESWT group and 59.4% in the sildenafil group (P>0.05). The EHS and SEAR improvement was similar in the 2 groups (P>0.05 at baseline and third month). Transient and mild adverse events were observed in both groups. In our study, a similar treatment efficacy and safety was shown by the application of Li-ESWT as on demand sildenafil. In our study, a similar treatment efficacy and safety was shown by the application of Li-ESWT as on demand sildenafil. Postoperative opioid prescribing has been linked with persistent opioid use. Ureteroscopy (URS) is a common urologic procedure and a potential area to focus on opioid reduction. We aim to characterize international practice patterns of opioid prescribing post URS and what measures may decrease the need for opioid prescription. We developed a survey directed to members of the Endourological Society. The survey queried the frequency of opioid prescribing post URS, challenges when opioids are not prescribed, and measures thought to reduce the need for opioids. We received 159 responses with the majority reported practicing urology for >20 years (37.1%), and performing 10-20 ureteroscopies/month (45.3%). Forty-one percent were from the United States (US) and Canada. Sixty-six percent completed a fellowship, 84% in endourology. Twenty-six percent prescribe opioids more than half the time and the majority do so less than 10% of the time (61.6%). Thirty-eight percent had no challenges when opioids were omitted.
