ABSTRACT
Objectives:
The objective of this study is to compare the changes in renal function and drainage following open dismembered pyeloplasty with and without renal pelvis reduction. Materials andMethods:
Randomized prospective study of children with ureteropelvic junction obstruction undergoing pyeloplasty with (Group 1) and without (Group 2) pelvis reduction over an 18-month period. Postoperative function and drainage were assessed by ethylene dicysteine (EC) scan and intravenous urography (IVU) and renal pelvis size by ultrasonography.Results:
Forty-two patients (2 months-11 years) participated. The mean preoperative EC scan function was Group 1 45.88% ± 14.42% (5%-80%) and Group 2 39.22% ± 9.75% (21%-53%). (P = 0.117). The mean postoperative EC scan function of Group 1 was 42.64% ± 9.62% (17%-54%) and 43.75% ± 9.88% (17%-58%) and of Group 2 was 44.77% ± 12.82% (20%-68%) and 42.25% ± 8.56% (23%-58%) at 3 months (P = 0.584) and ≥ 1year (P = 0.385), respectively, with no significant difference. None required re-do pyeloplasty. The number of patients with slow drainage, especially at 3 months and also at ≥1-year postoperative period on EC scan was slightly higher in Group 2 compared to Group 1 but did not attain statistical significance. There was postoperative improvement in function and drainage on IVU with no significant difference between the two groups, (P = 0.214; P = 0.99, respectively). At a mean follow-up of 45.5 months, Group 2 also showed significant reduction in pelvis size on ultrasound (P = 0.011).Conclusion:
Postoperative function remained stable in both groups. More number of patients achieved unobstructed drainage by 3 mo postoperative after reduction pyeloplasty but drainage patterns were mostly similar between reduction and nonreduction of pelvis group in late follow-up.
