Purpose: We evaluated the use of renal ultrasound for monitoring pyelocaliectasis after pyeloplasty in

Congenital Pelviureteric Junction Obstruction cases.

Materials and Methods: Serial ultrasound was performed to monitor the changes in the pyelocaliectasis

following pyeloplasty. 43 patients who were included in the study were followed for atleast one–year post

pyeloplasty. Serial ultrasound was performed preoperatively and at 6 and 12 months post operatively. The

degree of pyelocaliectasis was graded as 0 to 4 according to the classification of Society For Fetal

Urology. Renal parameters like renal length, pelvic diameter and renal parenchymal thickness were

measured at pre–op and successive post–op scans.

Results: Preoperative ultrasound revealed grade 4 pyelocaliectasis in 9 kidneys (20.9%), grade 3

pyelocaliectasis in 17 (39.5% ) and grade 2 in 16 (36.2 %). Grade were same or worst 6 months after

pyeloplasty in 13/43 patients (30 %). Majority of them i.e, 37/43 (86 %) showed improvement at 1year

post operatively. Improvement to grade 0 or 1 dilatation from grade 3 or grade 4 occurred in only 4

kidneys (10.8 %) at the end of 1 year. Serial ultrasound study also showed gradual improvement in the

renal parameters on follow up scans at 6 and 12 months compared to the preoperative scan.

Conclusions: Improvement in renal ultrasound after pyeloplasty appears to be gradual .The renal

ultrasound because of its cost effectiveness, easy availability and lack of radiation provides an accurate

and suitable means for the long term follow up of the patients who undergo pyeloplasty for Pelviureteric

Junction Obstruction.
