Background:We investigated potential disparities in health-related quality of life,particularly concerning urinary function,between patients with preserved and those with impaired sexual function after robot-assisted radical prostatectomy(RARP).Materials and methods:BetweenDecember 2012 and April 2020,704men underwent RARP in our *** study included 155 patients with a preoperative 5-item International Index of Erectile Function(IIEF-5)of≥12 points and an assessable IIEF-5 at 12 months ***-related quality of life was assessed using the 8-item Short-Form Health Survey and Expanded Prostate Cancer Index Composite(EPIC)preoperatively and at 3,6,and 12months postoperatively.A logistic regression analysis andWilcoxon rank sum tests were ***:Patients were grouped according to the median IIEF-5 score 12 months after surgery:those with preserved sexual function(n=71)and those with impaired sexual function(n=84).The mental component summary of the 8-item Short-Form Health Survey was better in the group with preserved sexual function at 6 months postoperatively than in the group with impaired sexual function(p<0.01).In the EPIC,the group with preserved sexual function performed better not only in the sexual domain but also in the urinary domain at all time points comparedwith the groupwith impaired sexual function(p<0.01).In the comparison of the urinary subdomains of the EPIC,there were no significant differences in urinary function or incontinence,but there were significant differences in urinary distress and irritative/obstructive scores(p<0.01).Conclusions:Patients with preserved postoperative sexual function after RARP showed better urinary function than those with impaired sexual ***,preserved sexual function is closely associated with urinary function.

西昌位于大凉山腹地,背靠安宁河谷,是一座春天栖息的城市,也是我出生的地方。年关将至,在外的游子思念家乡,跃然脑中的除了父亲母亲,便是过年回家团聚时的那一口西昌烧烤。那是这座城市最常见的晚餐,也是民族混居下食材和调料碰撞出的艺术。西昌烧烤的版图,其实可以拿来和武侠片里江湖各大门派相类比。武林门派依照地域、山头、宗教区分,而西昌的烧烤江湖,也按照各地不同的人口、风俗分化出不同的风格流派。更相似之处在于,烧烤和武功一样,各个门派都保有独特的招式秘籍,一般不轻易外传。烧烤在西昌,主要分为城南、城北、城东三大派系。
