Abstract:
Objective To analyze the frequency of pelvis peristalsis in children with hydronephrosis and its correlation with postoperative percentage of improvement in anteroposterior diameter (PI－APD).Methods From Oc-tober 2015 to September 2017,the data of the children with unilateral ureteropelvic junction obstruction (UPJO)hydro-nephrosis who underwent laparoscopic pyeloplasty were collected,and their pelvis peristalsis frequencies of 2 min were recorded after exposing the pelvis,while the APD and PI－APD were followed 1 year posto-peratively.The degrees of hydronephrosis were divided into mild,moderate and severe according to the Society of Fetal Urology(SFU)classifica-tion system.ANOVA was used to compare the pelvis peristalsis frequency and postoperative PI－APD between different degrees of hydronephrosis.Spearman analysis was used to analyze the correlation between pelvis peristalsis frequency and degree of hydronephrosis.Meanwhile,Pearson test was used to analyze the correlation between pelvis peristalsis fre-quency,hydronephrosis degree and PI－APD.Results A total of 50 children were included,of which 36 patients got follow－up for 1 year postoperatively.Pelvis 2 min peristalsis frequency between different degrees of hydronephrosis [mild:(8.1 ± 3. 3)times;moderate:(6.3 ± 3.5)times;severe:(7.8 ± 3.9)times]had no significant difference (F＝0.65,P＝0. 527);no statistical correlation was observed between pelvis peristalsis frequency and degree of hydro-nephrosis or PI－APD (all P ＞0.05).Preoperative hydronephrosis degree was positively correlated with PI －APD (r＝0.54,P＝0. 001).PI－APD in severe hydronephrosis (0.48 ± 0.29)was significantly higher than that of mild hydronephrosis (0.21 ± 0.20)(P ＝0.001 ). Conclusions For children with different degrees of hydronephrosis caused by UPJO,there was no significant difference in the pelvis peristalsis frequency recorded during laparoscopic pyeloplasty.Pelvis peristalsis frequency recorded during surgery was not correlated with PI －APD,but preoperative hydronephrosis degree was positively correlated with postoperative PI－APD.
