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 ***,2-week,1-month and 3-month continence recovery and other perioperative data were compared to evaluate short-term surgical and functional ***: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 ***-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 ***-term follow-up and prospective studies are required to further evaluate its value in postoperative quality-of-life improvement.

The unique crystal structure and multiple redox couples of iron titanate(Fe_(2)TiO_(5)) provide it a high theoretical capacity and good cycling stability when used as an electrode. In this study, the electrospinning method is employed to synthesize one-dimensional(1 D) Fe_(2)TiO_(5) nanochains. The as-prepared Fe_(2)TiO_(5) nanochains exhibited superior specific capacity(500 mAh·g^(-1) at 0.10 A·g^(-1)),excellent rate performance(180 mAh·g^(-1) at 5.00 A·g^(-1)),and good cycling stability(retaining 100% of the initial specific capacity at a current density of 1.00 A·g^(-1) after1000 cycles). The as-assembled Fe_(2)TiO_(5)/SCCB lithiumion capacitor(LIC) also delivered a competitive energy density(137.8 Wh·kg^(-1))andpowerdensity(11,250 W·kg^(-1)). This study proves that the as-fabricated1 D Fe_(2)TiO_(5) nanochains are promising anode materials for high-performance LICs.
