The Oxford English dictionary defines the term "simple" as "easily done" and "uncomplicated". We tested the validity of this terminology in relation to open nephrectomy surgery.
Retrospective review of 215 patients undergoing open, simple (n = 89) or radical (n = 126) nephrectomy in a single university-affiliated institution between 1998 and 2002. Operative time (OT), estimated blood loss (EBL), operative complications (OC) and length of stay in hospital (LOS) were analysed. Statistical analysis employed Fisher's exact test and Stata Release 8.2.
Simple nephrectomy was associated with shorter OT (mean 126 vs. 144 min; p = 0.002), reduced EBL (mean 729 vs. 859 cc; p = 0.472), lower OC (9 vs. 17%; 0.087), and more brief LOS (mean 6 vs. 8 days; p < 0.001).
All parameters suggest favourable outcome for the simple nephrectomy group, supporting the use of this terminology. This implies "simple" nephrectomies are truly easier to perform with less complication than their radical counterpart.
《牛津英语词典》将“简单”一词定义为“易于完成”和“不复杂”。我们在开放性肾切除术方面测试了这一术语的有效性。
对 1998 年至 2002 年间在一家大学附属医院接受开放性简单（n=89）或根治性（n=126）肾切除术的 215 例患者进行回顾性分析。分析手术时间（OT）、估计失血量（EBL）、手术并发症（OC）和住院时间（LOS）。统计学分析采用 Fisher 确切检验和 Stata Release 8.2。
简单肾切除术与较短的 OT（平均 126 对 144 分钟；p=0.002）、减少的 EBL（平均 729 对 859 cc；p=0.472）、较低的 OC（9 对 17%；0.087）和更短的 LOS（平均 6 对 8 天；p<0.001）相关。
所有参数均表明简单肾切除术组的预后良好，支持这一术语的使用。这意味着“简单”的肾切除术确实比根治性手术更容易操作，并发症也更少。
