Urinary tract infection (UTI) is one of the most common complications after radical cystectomy and orthotopic neobladder reconstruction. This study investigated the incidence and implicated pathogen of febrile UTI after ileal neobladder reconstruction and identify clinical and urodynamic parameters associated with febrile UTI. From January 2001 to May 2015, 236 patients who underwent radical cystectomy and ileal neobladder were included in this study. Fifty-five episodes of febrile UTI were identified in 46 patients (19.4%). The probability of febrile UTI was 17.6% and 19.8% at 6 months and 24 months after surgery, respectively. While, Escherichia coli was the most common implicated pathogen (22/55, 40.0%), Enterococcus spp. were the most common pathogen during the first month after surgery (18/33, 54.5%). In multivariate logistic regression analysis, ureteral stricture was an independent risk factor associated with febrile UTI (OR 5.93, P = 0.023). However, ureteral stricture accounted for only 6 episodes (10.9%, 6/55) of febrile UTI. Most episodes of febrile UTI occurred within 6 months after surgery. Thus, to identify risk factors associated with febrile UTI in the initial postoperative period, we assessed videourodynamics within 6 months after surgery in 38 patients. On videourodyamic examination, vesicoureteral reflux (VUR) was identified in 16 patients (42.1%). The rate of VUR presence in patients who had febrile UTI was not significantly different from those in patients without febrile UTI (50% vs. 39.3%, P = 0.556). Patients with febrile UTI had significantly larger residual urine volume (212.0 ± 193.7 vs. 90.5 ± 148.2, P = 0.048) than those without. E. coli and Enterococcus spp. are common pathogens and ureteral stricture and residual urine are risk factors for UTI after ileal neobladder reconstruction.
尿路感染(UTI)是根治性膀胱切除术和原位新膀胱重建术后最常见的并发症之一。本研究调查了回肠新膀胱重建术后发热性UTI的发病率及相关病原体,并确定了与发热性UTI相关的临床和尿动力学参数。2001年1月至2015年5月,本研究纳入了236例行根治性膀胱切除术和回肠新膀胱术的患者。46例患者(19.4%)发生了55次发热性UTI。术后6个月和24个月时发热性UTI的发生率分别为17.6%和19.8%。同时,大肠埃希菌是最常见的相关病原体(22/55,40.0%),肠球菌属是术后第一个月最常见的病原体(18/33,54.5%)。在多因素logistic回归分析中,输尿管狭窄是与发热性UTI相关的独立危险因素(OR 5.93,P = 0.023)。然而,输尿管狭窄仅占发热性UTI的6次发作(10.9%,6/55)。大多数发热性UTI发作发生在术后6个月内。因此,为了确定术后初期与发热性UTI相关的危险因素,我们对38例患者在术后6个月内进行了视频尿动力学检查。在视频尿动力学检查中,16例患者(42.1%)发现了膀胱输尿管反流(VUR)。发生发热性UTI的患者中VUR的发生率与未发生发热性UTI的患者相比无显著差异(50%对39.3%,P = 0.556)。发热性UTI患者的残余尿量明显多于未发生发热性UTI的患者(212.0±193.7对90.5±148.2,P = 0.048)。大肠埃希菌和肠球菌属是常见病原体,输尿管狭窄和残余尿量是回肠新膀胱重建术后UTI的危险因素。
