Meta-analysis of the comparative effectiveness between lingual and buccal mucosa in the treatment of ureteral strictures
Objective:To describe the results of lingual mucosa ureteroplasty and buccal mucosa ureteroplasty,and to determine the relative advantages of the two kinds of autologous tissues,so as to provide evidence-based proof for clinical treatment of ureteral stricture.Methods:We searched the databases(including PubMed,Web of Science,The Cochrane Library,CNKI and WanFang Data)from date of establishment to December 27th,2023 to find the trials evaluating the results of lingual mucosa ureteroplasty and buccal mucosa ureteroplasty.The varia-bles analyzed included success rate of reconstruction,length of stenosis,length of hospital stay,perioperative complications and long-term complications.Results:A total of 220 patients with 16 single arm studies were in-cluded.The success rates of reconstruction in lingual mucous membrane group and buccal mucosa group were 99.0%(95%CI:95.0%-100.0%)and 94.0%(95%CI:88.0%-99.0%),respectively.The length of repair in lingual mucous membrane group and buccal mucosa group were 4.25 cm(95%CI:3.52-4.98)and 3.81 cm(95%CI:2.99-4.63),respectively.The hospitalization time of lingual mucous membrane group and buccal mu-cosa group were 7.37 days(95%CI:6.01-8.74)and 5.45 days(95%CI:0.95-9.96),respectively.The inci-dence of postoperative complications in lingual mucous membrane group and buccal mucosa group were 16.0%(95%CI:7.0%-26.0%)and 26.0%(95%CI:14.0%-41.0%).The incidence of postoperative complications in low-level group were 14.0%(95%CI:6.0%-25.0%)and 16.0%(95%CI:6.0%-29.0%).The incidence of high-level postoperative complications of the two groups were both 5.0%(95%CI:1.0%-12.0%).Conclu-sion:The available evidence shows that compared with buccal mucosa patch,lingual mucosa patch has advantages in operation success rate,autologous tissue removal length and postoperative complication rate.In order to com-pare and prove the effect of lingual mucosa patch and buccal mucosa patch in clinical application,large samples,long-term follow-up and high-quality researches are needed to further verify.
