排尿相膀胱尿道造影已经成为查明膀胱输尿管返流并对其进行分级的标准。尽管膀胱造影是选择术式和解释治疗效果的依据,但无统一的分级方法。这种情况不但难以对不同组的病例加以比较,而且还不利于了解返流分级与临床预后的联系。回顾已采用的各种分级方法,作者认为国际返流委员会提出的标准(由欧洲的Heikel和Parkkulainen及美国的Dwoskin和Perlmutter所提出)为可取,值得推荐一种国际性返流分级法加以采用。
Urinary bladder and urethrophagogram has become the standard to identify vesicoureteral reflux and grade it. Although cystography is the basis of choice and explanation of the therapeutic effect, there is no uniform classification method. This situation is not only difficult to compare different groups of patients, but also not conducive to understanding the relationship between reflux classification and clinical prognosis. Recalling the various classification methods that have been adopted, the authors consider the criteria proposed by the International Commission on Reflux (proposed by Heikel and Parkkulainen in Europe and Dwoskin and Perlmutter in the United States) as desirable and recommend the use of an international regurgitant classification.
