The Mayo Adhesive Probability (MAP) score is a radiographic scoring system that predicts the presence of adherent perinephric fat (APF) during partial nephrectomies (PNs). The purpose of this systematic review is to summarize the current literature on the application of the MAP score for predicting intraoperative difficulties related to APF and complications in laparoscopic PNs. Three databases, PubMed, Scopus and Cochrane, were screened, from inception to 29 October 2023, taking into consideration the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines. All the inclusion criteria were met by eight studies. The total operative time was around two hours in most studies, while the warm ischemia time was <30 min in all studies and <20 min in four studies. Positive surgical margins, conversion and transfusion rates ranged from 0% to 6.3%, from 0% to 5.0% and from 0.7% to 7.5%, respectively. Finally, the majority of the complications were classified as Grade I-II, according to the Clavien–Dindo Classification System. The MAP score is a useful tool for predicting not only the presence of APF during laparoscopic PNs but also various intraoperative and postoperative characteristics. It was found to be significantly associated with an increased operative time, estimated blood loss and intraoperative and postoperative complication rates.
梅奥粘连概率（MAP）评分是一种影像学评分系统，用于预测肾部分切除术中是否存在粘连性肾周脂肪。本系统综述旨在总结当前关于MAP评分在预测腹腔镜肾部分切除术中与粘连性肾周脂肪相关的手术困难及并发症方面的应用文献。根据系统综述和荟萃分析优先报告项目指南，我们检索了PubMed、Scopus和Cochrane三个数据库自建库至2023年10月29日的文献。最终纳入八项符合所有纳入标准的研究。多数研究中总手术时间约为两小时，所有研究的热缺血时间均小于30分钟，其中四项研究小于20分钟。手术切缘阳性率、中转开放手术率和输血率分别为0%-6.3%、0%-5.0%和0.7%-7.5%。根据Clavien-Dindo分级系统，大多数并发症为I-II级。MAP评分不仅能有效预测腹腔镜肾部分切除术中粘连性肾周脂肪的存在，还能预测多种术中及术后特征。研究发现该评分与手术时间延长、估计失血量增加以及术中术后并发症发生率显著相关。
