  • Title: Management of ureteropelvic junction obstruction in infants and neonates.
    Author: Aliabadi H, Ami Sidi A, Gonzalez R.
    Journal: Eur Urol; 1988; 15(1-2):103-7. PubMed ID: 3063535.
    Abstract:
    From June 1980 to October 1985 we performed 22 ureteropyeloplasties on 20 infants and neonates with ureteropelvic junction obstruction. All patients were males less than 2 years old; 12 were less than 1-month-old. The diagnosis was suspected on the basis of maternal ultrasonography in 10 patients (50%), a palpable abdominal mass was the presenting symptom in 7 (35%), and obstruction was detected during evaluation of congenital heart disease in 3 (15%). This change in mode of presentation is expected to become even more pronounced as the use of fetal ultrasonography increases. All patients in whom the diagnosis was suspected antenatally underwent ultrasonography after birth to confirm the presence of hydronephrosis. All 22 obstructed kidneys were repaired by a dismembered technique under optical magnification. There were no operative mortalities. Of 21 postoperative intravenous pyelograms available, 3 demonstrated marked improvement, 17 showed improvement with residual hydronephrosis, and 1 showed deterioration. The methods used to diagnose, treat and evaluate ureteropelvic junction obstruction in 20 infants and neonates are presented. Given the existing clinical and experimental data we advocate early postnatal surgical correction of ureteropelvic junction obstruction to achieve a maximum recovery of renal function.
