Objective: The most typical type of obstruction in the upper urinary tract is ureteropelvic junction obstruction or UPJO. The objective of this study was to assess the effectiveness and long-term results of pyeloplasty in children with poorly functioning kidneys.
Method: Patients who underwent pyeloplasty at Department of Urology, Rajendra Institute of Medical Science, Ranchi for last twelve years were the subject of a retrospective data study. Postoperative outcome was the parameter under study. Success was measured by either symptom improvement or better drainage on postoperative Tc-99m DTPA renography, which was performed after two months and then yearly after that.
Results: 60 individuals were enrolled in the study, with a mean age of 8.5 years (3 months to 12 years), a male-to-female ratio of 2:1, and poor function on the isotope renogram (31%). The ratio of left to right sides was 1.2:1. All patients had dismembered pyeloplasty procedures. 37 patients (66.8%) underwent laparoscopic pyeloplasty, whereas 23 (33.2%) underwent open surgery. 35 patients had follow-up renograms available; of these, 30 showed improved drainage and no further decline in renal function, while 5 displayed an obstructed pattern; of these, 3 patients had noticeably worsened split function, and the other two underwent a second open pyeloplasty. A mean follow-up of 21.5 months revealed a 91% overall success rate.
Conclusion: In the pediatric age group, pyeloplasty provides satisfactory intermediate results in kidneys with inadequate function.
