Rationale:
Hydronephrosis, mostly caused by ureteropelvic junction obstruction, rarely occurs in infants. However, imperforate hymen atresia in female infants may cause hydronephrosis, even though it is rare.
Patient Concerns:
A 3-month-old female infant was admitted to our hospital for frequent crying. There was no significant past medical history.
Diagnoses:
Following ultrasound imaging, the patient was diagnosed with hydronephrosis possibly caused by imperforate hymen.
Interventions:
The infant underwent hymenotomy with a cruciate incision to prevent future complications such as acute renal injury.
Outcomes:
Hydronephrosis resolved after the operation. The outcome was very good, with no complications in the postoperative period.
Conclusions:
Early ultrasound diagnosis plays a significant role in the management and treatment of infant patients. Ultrasound is the mandatory imaging technology for determining the cause of hydronephrosis.
