From January 1988 to January 1996, 42 infants and children (44 renal units) had
undergone surgical management to correct ureteropelvic junction obstruction. Median
patient loge was 8.5 years (rang from 2 months to 17 years) and 11patients were less
than 1 year old at operation.
Of 44 renal units surgically managed, 30 were on the left side find 10 were right side.
2 patients had undergone bilateral surgical management. Presenting symptoms were
febrile urinary tracts infection in 14 cases, abdominal pain in 14 cases, abdominal mast
in 5 cases, gross hematuria in 3 cases and 3 cases were detected prenatally.
We used imaging antegrade pyelography (AGP) in 15 cases, additional retrograde
pyelography (RGP) in 12 cases and both AGP and RGP were performed in 1 case.
To correct ureteiopelvic junction obstruction, we performed dismembered pyeloplasty in
33 renal units, ureterolysis in 2 renal units, ureterocalycostomy in 1 renal unit,
endopyelotomy in 1 renal unit and nephrectomy in 7 renal units.
To diverge the urinary flow, we used nephrustomy in 19 renal units, ureteral stenting
in 6 renal units and both nephrostomy and ureteral stenting were used in 10 renal units.
As postoperative complications, restenosis was developed in 5 renal units, delayed
open in 5 renal units, urinary tract infection in 2 renal units and wound infection,
prolonged urine leakage, ureteral stone in each 1 renal unit.
Postoperative success rate in followed-up patients, who had undergone pyeloplasty,
was 91.6%. The success rate in children, who was less than 1 year old, was 100% and
in children, who was more than 1 year old, was 88.4%.
Finally we suggest that the surgical correction is safe and proper method for
ureteropelvic junction obstruction in children. Additionally early operation of ureteropelyic
junction obstruction is recommandable
