Objective To evaluate renal pelvis peristalsis for different degrees of hydronephrosis. Methods Between October 2015 and June 2016,24 children with unilateral hydronephrosis as diagnosed by ultrasound were included.All children underwent retrograde ureteral catheter catheterization to hydronephrosis pelvis through cystoscopy and 21 cases underwent simultaneous catheterization to the contralateral pelvis.Both ureteral catheters were connected to the pressure sensor of Laborie and renal pelvis peristalsis frequency of 2 minutes was recorded.Then retrograde ureteropyelography was performed for confirming the position of catheter.Renal pelvis peristalsis frequency was also recorded in the following laparoscopic pyeloureteroplasty and compared with the frequency recorded by Laborie.Also renal pelvis peristalsis frequency was compared between different degrees of hydronephrosis. Results Bilateral renal pelvic peristalsis frequency of 2 minutes was successfully recorded by LABORIE in 12 patients.The 2 min pelvis peristalsis frequency (median and four minute intervals) were 7.0 (IQR:3.8-8.5) respectively and 2 min pelvis peristalsis frequency (median and four minute intervals) recorded by surgery 7.5 (IQR:4.5-10.5).No significant difference ( Z =-1.38, P =0.167) was observed.For mild- moderate degree hydronephrosis,2 min peristalsis frequency of hydronephrosis pelvis (median and four minute intervals) (8.5(IQR:7.0-11.5)) was significantly higher ( Z =-2.23, P =0.026) than that at normal side (6.0(IQR:5.0-7.5)).The 2 min pelvis peristalsis frequency for severe degree hydronephrosis (median and four minute intervals) (6.0(IQR:4.0-6.5)) was lower than normal pelvis (10.5(IQR:8.5-11.2)), Z =-2.21, P =0.027. Conclusion Renal pelvis peristalsis frequency may be recorded by a retrogradely inserted ureteral catheter.For unilateral hydronephrosis due to ureteropelvic junction obstruction,pelvis peristalsis frequency of mild-moderate hydronephrosis is higher than normal side.However,for severe hydronephrosis,peristalsis frequency of hydronephrosis pelvis is lower than normal pelvis.
