■我们的目的是调查围手术期结局的差异,尤其是输尿管肠系膜狭窄,在机器人辅助根治性膀胱切除术(RARC)和回肠导管时接受了输尿管肠管支架吻合术的患者与未接受的患者之间。
■对我们的RARC数据库进行了回顾性审查(2009-2023年)。患者分为接受输尿管肠管支架吻合术的患者和未接受支架吻合术的患者。在年龄方面,以3(支架输尿管肠吻合)与1(无支架)的比例进行倾向评分匹配,性别,BMI,种族,美国麻醉医师协会评分,新辅助化疗,Charlson合并症指数,先前的放射治疗,既往腹部手术史,临床T3/临床T4分期,术前转移,术前肾积水.使用累积发生率曲线来描绘输尿管肠系膜狭窄,并使用Cox回归模型来识别与输尿管肠系膜狭窄相关的变量。
■488名患者接受了RARC,366人接受了输尿管肠管支架吻合术,122例患者接受了无支架入路。90天总体并发症没有显着差异,严重并发症,再入院,UTI,泄漏,肠梗阻(P>0.05)。在1年和2年,输尿管肠系膜狭窄的发生率分别为13%和18%。分别在支架组中,无支架组分别为7%和10%(P=0.05)。支架放置与输尿管肠系膜狭窄显着相关。
■无支架输尿管肠吻合与RARC和回肠导管后狭窄较少相关。
UNASSIGNED: We aimed to investigate the differences in perioperative outcomes, especially ureteroenteric
strictures, between patients who underwent a stented ureteroenteric anastomosis at the time of robot-assisted radical cystectomy (RARC) and ileal conduit vs those who did not.
UNASSIGNED: A retrospective review of our RARC database was performed (2009-2023). Patients were divided into those who received stented ureteroenteric anastomosis vs those who did not. Propensity score matching was performed in the ratio of 3 (stented ureteroenteric anastomosis) to 1 (stent-free) in terms of age, gender, BMI, race, American Society of Anesthesiologists score, neoadjuvant chemotherapy, Charlson Comorbidity Index, prior radiation therapy, previous abdominal surgery history, clinical T3/clinical T4 stage, preoperative metastasis, and preoperative hydronephrosis. A cumulative incidence curve was used to depict ureteroenteric
strictures and a Cox regression model was used to identify variables associated with ureteroenteric
strictures.
UNASSIGNED: Four hundred eighty-eight patients underwent RARC, 366 individuals underwent a stented ureteroenteric anastomosis, and 122 patients underwent a stent-free approach. There was no significant difference in 90-day overall complications, high-grade complications, readmissions, UTIs, leakage, and ileus (P > .05). Ureteroenteric
strictures occurred at a rate of 13% and 18% at 1 and 2 years, respectively in the stented group, vs 7% and 10% in the stent-free group (P = .05). Stent placement was significantly associated with ureteroenteric
strictures.
UNASSIGNED: Stent-free ureteroenteric anastomosis was associated with fewer strictures following RARC and ileal conduit.
