Sustainable functional urethral reconstruction:Maximizing early continence recovery in robotic-assisted radical prostatectomy

Objective:To evaluate the safety profile and short-term functional outcome of sustainable functional urethral reconstruction(SFUR)in robotic-assisted radical prostatectomy(RARP).Methods:One hundred and sixty-two consecutive prostate cancer patients who underwent RARP were retrospectively analyzed,in which 53 had undergone SFUR while the other 109 had undergone conventional RARP procedures.Immediate,2-week,1-month and 3-month continence recovery and other perioperative data were compared to evaluate short-term surgical and functional outcome.Results:The median age was 68 and 67 years in the experimental group and control group,respectively(pZ0.206),with a median prostate-specific antigen(PSA)of 13.6 ng/mL(interquartile range[IQR],8.46e27.32 ng/mL)in the experimental group and 13.84 ng/mL(IQR,9.12e26.80 ng/mL)in control group(pZ0.846).Immediate,2-week,1-month and 3-month continence recovery rates between the groups were 34.0%vs.3.7%,50.9%vs.14.7%,62.3%vs.27.5%,and 79.2%vs.63.3%(all p<0.05).The morphological changes made by the new reconstruction technique were maintained on magnetic resonance imaging(MRI)3 months postoperatively.Nerve-sparing procedures and adoption of the new reconstruction technique were significantly relevant to continence recovery on logistics regression model(p<0.001).Conclusions:SFUR is a safe and easy-to-handle modification that may contribute to early continence return for RARP.Long-term follow-up and prospective studies are required to further evaluate its value in postoperative quality-of-life improvement.

Ecological Evaluation Models for Environmental Engineering in Taiwan

This study is aimed to investigate and analyze the ecological technology around ecological environment resources of engineering in Taiwan. In Taiwan, the natural and artificial material applied in the ecological technology in internal currently, usually lack of evaluation for applicative conditions. Hence, this study carried on the whole research and identifications to draft the eco-materials of ecological technology. The evaluation models of applied materials for ecological technology were proposed. The quantitative score were obtained by expert＇s person evaluation. Three models were proposed to quantify the effects of applied materials on the ecological environment. The statistical procedures were adopted to compare the performance of these materials for ecological technology. The results indicated that the comparison of applied materials can be treated by quantitative analysis. For the further analysis, more evaluated data from expert＇s experience need to be collected then the bias of person subject can be reduced. In addition to reach the benefits in the respects of ecosystem, society, economy and function, also practice the comprehensive effects in ecological technology.
