Background: Urosepsis is an acute life-threating disease, and some cases show refractory outcome to therapy. In an aging society of developed countries, characteristics of urosepsis are becoming complicated. We performed a comprehensive investigation regarding the clinical and social aspects that are related to refractory outcomes in urosepsis patients. Methods: The patient cohort consisted of 66 patients with urosepsis. Multiple factors from clinical and social aspects were reviewed retrospectively. Two categories of refractory outcomes were defined. One was afebrile resistance (AR); fever continued more than 7 days from the initiation of therapy. Another was discharge resistance (DR); hospitalization continued for more than 30 days. Logistic regression analyses were performed to identify significant factors that are related to the AR or DR. Results: Univariate analysis demonstrated that high score of Eastern Cooperative Oncology Group Performance Status (ECOG PS) (? 2) and Age-adjusted Charlson comorbidity index (CCI) (? 4), high serum C-reactive protein (CRP) level (? 14.9 mg/dL), and low serum albumin level (? 2.26 g/dL) were significantly related to AR. Univariate analysis results also revealed that high score of ECOG PS (? 2), high serum creatinine level (? 1.54 mg/dL) and vasopressor administration were significantly related to DR. Multivariate analyses demonstrated that low serum albumin level (? 2.26g/dL) was the only significant factor that was related to AR. In contrast, high score of ECOG PS (? 2) and high serum creatinine level (? 1.54 mg/dL) were significant factors that were related to DR. Conclusion: It is suggested that evaluating serum albumin levels is essential for the therapeutic first step because hypoalbuminemia was the significant factor that was related to obstruction to antipyresis. It is also suggested that the deterioration of patients’ activities of daily living and renal dysfunction might be the refractory factors for discharge from the hospital, which was the ultimate therapeutic goal.

Background: The aim of this study is to evaluate the efficacy and safety of tadalafil, a phosphodiesterase type 5 inhibitor, plus mirabegron, a β3-adrenoreceptor agonist, in patients with benign prostatic hyperplasia who presented with persistent storage symptoms after tadalafil monotreatment. Methods: The registration of this study started in August 2016 and ended in July 2019. The inclusion criteria included patients aged ? 50 years who were diagnosed with benign prostatic hyperplasia and who presented with overactive bladder symptoms. Patients were treated with oral tadalafil 5 mg once daily for 4 weeks. Then, its efficacy was evaluated. Patients who responded to the treatment received oral tadalafil 5 mg once daily for 4 more weeks (monotreatment group). Meanwhile, those who did not respond received oral tadalafil 5 mg and mirabegron 50 mg, which is an add-on treatment, once daily for 4 more weeks (combination therapy group). Results: After 8 weeks, the monotreatment group (n = 19) and the combination group (n = 56) had significantly better total Overactive Bladder Symptom Score and International Prostate Symptom Score and International Prostate Symptom Score voiding and storage subscale scores. Moreover, the two groups experienced significant improvements in the total Overactive Bladder Questionnaire and Nocturia Quality of Life Questionnaire scores, and Nocturia Quality of Life Questionnaire Bother/Concern subscale score after 8 weeks. However, there were no cases of urinary retention or serious adverse events. Conclusion: Combination treatment with tadalafil and mirabegron is effective and safe for patients with benign prostatic hyperplasia who presented with persistent storage symptoms after tadalafil monotreatment. Hence, tadalafil plus mirabegron is a promising therapeutic option, and it can improve overactive bladder related-quality of life.

Background: We wanted to clarify whether preoperative magnetic resonance imaging (MRI) in the clinical setting can evaluate the pathologic pseudocapsule (PC) morphology with high accuracy in renal cell carcinoma (RCC). Methods: We retrospectively analyzed 34 consecutive patients who underwent MRI (1.5 or 3.0T, 5 mm slices) prior to partial nephrectomy (PN) for RCC at our institution between January 2010 and December 2019. First, the correlation between PC morphology (complete or incomplete) and tumor infiltration to the renal parenchyma was examined as pathologic validation. Second, the concordance rate of PC morphology between pathologic tissue and preoperative MRI was evaluated as radiologic validation. Third, risk factor for renal parenchymal invasion in RCC was analyzed. Results: In the pathologic validation, parenchymal invasion rates were 11% and 28% in the “complete PC” and “incomplete PC” groups, respectively. In the radiologic validation, pathological PC morphology could be diagnosed on preoperative MRI in 17 patients (50.0%). “None PC” on MRI had the lowest positive predictive value (PPV) (0%), “partial PC” on MRI had a good PPV (76.5%), “complete PC” on MRI had a relatively low PPV (33.3%). Unfortunately, these data were insufficient for diagnostic accuracy. As risk factor for renal parenchymal invasion in RCC, only pathologic subtype (non-clear cell) was found to have significant differences in the multivariate analysis. Conclusion: The results of this study suggest that renal tumors with pathologically incomplete PC have a high possibility of renal parenchymal invasion. However, it is currently difficult to accurately evaluate pathologic PC morphology by preoperative MRI in the clinical setting.

Background Radical prostatectomy and radiotherapy are standard treatments for localized prostate cancer. When making decisions about treatment, it is important to not only consider medical information such as the patient's age, performance status, and complications, but also the impact on quality of life (QOL) after treatment. Our purpose was to compare health related quality of life (HRQOL) after robot-assisted laparoscopic radical prostatectomy (RARP) versus radiation therapy in Japanese patients with localized prostate cancer retrospectively. Methods Patients with localized prostate cancer receiving RARP or radiotherapy at Tottori University Hospital between October 2010 and December 2014 were enrolled in a retrospective observational study with follow-up for 24 months to December 2016. The Medical Outcome Study 8-Item Short-Form Health Survey was performed before treatment and 1, 3, 6, 12, and 24 months post-treatment. Results Complete responses to the questionnaire were obtained from 154/227 patients receiving RARP, 41/67 patients receiving intensity-modulated radiation therapy, 35/82 patients receiving low dose rate brachytherapy, and 18/28 patients given low dose rate brachytherapy plus external beam radiation therapy. The median physical component summary score of the Medical Outcome Study 8-Item Short-Form Health Survey was significantly lower at 1 month after prostatectomy than radiotherapy, but was similar for both treatments at 3 months, and was significantly higher at 6, 12 and 24 months after prostatectomy. The median mental component summary score was also significantly lower in the prostatectomy group at 1 month, but not from 3 months onwards. Conclusion Our study suggested that HRQOL was inferior at 1 month after RARP, however, recovered at 3 months after RARP and was better than after radiotherapy at 6, 12, and 24 months.

BACKGROUND: To evaluate the efficacy of Bacilli Calmette-Guerin (BCG) induction instillation therapy after second transurethral resection (TUR) in stage Ta T1 high-grade bladder cancer. METHODS: We performed a retrospective analysis of 49 consecutive new onset Ta T1 high-grade bladder cancer patients treated with second TUR at our affiliated institutions. Residual cancer rate, intravesical recurrence-free survival (RFS), and risk factors related to RFS were evaluated by univariate and multivariate Cox proportional hazard model analyses. RESULTS: Thirty-one patients received BCG therapy after the second TUR (BCG group), and 18 patients were treated with second TUR alone (no BCG group). There were statistically significant differences in the RFS rates between the two groups, (P = 0.037). BCG therapy was the only factor predictive of intravesical recurrence after second TUR in both univariate and multivariate analyses. After the second TUR, BCG therapy significantly decreased intravesical recurrence in the patients with residual tumors (P = 0.014). However, there was no significant difference in intravesical recurrence in the patients with no residual tumors between the two groups (P = 0.359). CONCLUSION: BCG therapy after second TUR significantly decreased intravesical recurrence of residual tumors found at the second TUR.
