Implication

Observational study reveals conservative management succeeds for most infants with well-functioning hydronephrotic kidneys, indicating immediate pyeloplasty is unnecessary.

Key Points

To determine the optimal postnatal surgical and observational management strategy for infants presenting with hydronephrosis diagnosed via prenatal ultrasonography.
Evaluated 112 consecutive infants (142 kidneys) with suspected ureteropelvic junction obstruction diagnosed on prenatal ultrasound.
Assessed postnatal renal function at 3 months using isotope imaging to stratify kidneys into poor, moderate, or good function groups for surgical or conservative management.
Among 100 kidneys with good initial function managed conservatively, 23 (23.0%) required delayed pyeloplasty during follow-up primarily due to functional decline, while 77 remained surgery-free.
Of 27 kidneys with moderate function, 23 underwent pyeloplasty, with 14 of the 23 (60.9%) demonstrating improved function postoperatively.
Of 9 kidneys with poor baseline function, 3 recovered sufficient function following temporary pigtail drainage to warrant pyeloplasty.
