To determine the role of race in surgical outcomes of and complications after urethroplasty.
A single institution, retrospective review was conducted from 2011 to 2019 on male patients ≥18 years of age who underwent urethroplasty. Exclusion criteria included previous urethral cancer, lack of follow up, or revision urethroplasty. Failure of urethroplasty was defined as requiring revision surgery or recurrence on imaging or cystoscopy. Risk factors for recurrence were determined using descriptive statistics, Wilcoxon comparisons, and multivariate logistic regression.
Three hundred and seven patients were identified with 234 patients meeting inclusion criteria. 63.2% identified as White/Caucasian (CA), 32.5% Black/African American (AA), and 4.3% other race. Mean age was 49.4 years. Between CA and AA patients, there was no difference in mean age, body mass index, smoking status, prior urethroplasty, or prior dilation/DVIU. CAs were more likely to have a fossa navicularis stricture compared to AAs (P = .0094), but there were no significant differences in bulbar, penile, or posterior stricture rates (all P >.05) or length (P = .32). The overall stricture recurrence rate was 15.8% with a median of 242 days to recurrence and no significant difference by race for either outcome (P = .83, P = .64). The only predictor of stricture recurrence was prior dilation/DVIU (P = .0404, OR 2.3, 95% CI 1.0, 5.6). Overall complication rate was 17.5%, with no difference between CA and AAs rates (P = .83) or complication type (P = .62).
There was no significant difference in the rate of surgical failure for urethral stricture repair based on race. The only predictor of surgical failure was having a prior urethral dilation/DVIU.
确定种族在尿道成形术的手术结果和术后并发症中的作用。
对 2011 年至 2019 年间在我院接受尿道成形术的年龄≥18 岁的男性患者进行了单中心回顾性研究。排除标准包括既往尿道癌、缺乏随访或再次尿道成形术。尿道成形术失败定义为需要再次手术或影像学或膀胱镜检查显示复发。使用描述性统计、Wilcoxon 比较和多变量逻辑回归来确定复发的危险因素。
共确定了 307 例患者,其中 234 例符合纳入标准。63.2%的患者为白人/高加索人(CA),32.5%为黑人/非裔美国人(AA),4.3%为其他种族。平均年龄为 49.4 岁。在 CA 和 AA 患者之间,平均年龄、体重指数、吸烟状况、既往尿道成形术或既往扩张/尿道内切开术无差异。CA 患者比 AA 患者更有可能患有舟状窝狭窄(P = .0094),但在球部、阴茎部或后部狭窄率(所有 P >.05)或长度(P = .32)上无显著差异。总的狭窄复发率为 15.8%,复发中位时间为 242 天,种族间无显著差异(P = .83,P = .64)。狭窄复发的唯一预测因素是既往扩张/尿道内切开术(P = .0404,OR 2.3,95%CI 1.0,5.6)。总的并发症发生率为 17.5%,CA 和 AA 之间的发生率无差异(P = .83)或并发症类型(P = .62)。
基于种族,尿道狭窄修复的手术失败率无显著差异。手术失败的唯一预测因素是既往尿道扩张/尿道内切开术。
