- 16-mo female patient presents for evaluation.
- She had the prenatal diagnosis of ureterocele.
- Images obtained postnatally included ultrasound that showed bladder with a cystic mass behind it with layering of two different types of fluid. This was a hydrocolpos.
- MRI postnatally showed the bladder compressed by a giant hydrocolpos. This is more easily identified on sagittal MRI images.
- Patient underwent excision of urachal cyst and attempted vaginal septum removal.
- Follow-up images showed re-accumulation of the hydrocolpos.
- Patient had a 2-cm urogenital sinus with a normal anus.
- Urogenital mobilization was performed.
- Characteristic ultrasound findings of hydrocolpos include a cystic structure located posteriorly to the bladder often with layering of fluid. The fluid is usually mucous and urine.
- Hydrocolpos is a common finding in patients with cloaca but also occurs in patients with urogenital sinus.
- If the urogenital sinus is longer (3 cm and greater), the anus and rectum may need to be divided in order to perform the reconstruction.
- Consent for laparotomy should always be obtained preoperatively just in case the surgery requires an abdominal approach.
