A 14-year-old, adolescent female was referred to the Department of Imaging for pelvic ultrasonography with complaints of recurrent urinary tract infections since childhood which had increased in frequency over the course of last 6 months. Patient was obese (weight: 72 kg and height: 1.6 m (body mass index = 28.12 kg/m2)). Menstrual history was unremarkable and clinical examination revealed normal external genitalia. Internal examination was not performed as the patient did not consent for the same. Renal function tests and blood counts were in the normal range. Urine microscopy revealed pus cells, epithelial cells, and gram-negative bacteria. Urine culture revealed Escherichia coli. Ultrasonography revealed an anechoic lesion posterior to the distended urinary bladder causing its anterior displacement with posterior acoustic enhancement. It was causing superior displacement of the uterus and outlining the cervical os [Figure 1]a, therefore, consistent with a fluid-filled vagina (hydrocolpos). Uterus, bilateral ovaries, and urinary bladder were normal. The post-void scan revealed complete resolution of the hydrocolpos, suggesting a plausible diagnosis of vesicovaginal reflux [Figure 1]b. Thereafter, Magnetic Resonance Imaging (MRI) of the pelvis was done which revealed distended fluid-filled vagina on full bladder imaging suggestive of hydrocolpos [Figure 2]a. Mass effect due to hydrocolpos was noted on the adjacent structures like urinary bladder and uterus. The post void MRI revealed resolution of the fluid-filled vaginal distension [Figure 2]b. There was no evidence of an ectopic ureter, vesicovaginal fistula, bladder diverticuli or any other structural abnormality, thereby cementing the diagnosis of non-obstructive hydrocolpos due to vesicovaginal reflux. The patient was advised to undergo behavioral therapy with a voiding retraining program, including the proper toileting position, as a part of her management.

Hydrocolpos refers to the dilatation of vagina due to fluid, which could be cervical or endometrial secretions or rarely urine. Etiology is either obstructive (transverse vaginal septum, imperforate hymen, vaginal atresia, vaginal agenesis) or non-obstructive (misplaced bladder catheter, vesicovaginal reflux, leakage of amniotic fluid in pregnant patient). Vesicovaginal reflux (VVR) though a common entity, is an uncommon cause of hydrocolpos. VVR is a functional voiding disorder which falls under the umbrella of a spectrum of diseases referred to as dysfunctional elimination syndrome. VVR has variable clinical presentation ranging from asymptomatic bacteriuria, enuresis to vulvovaginitis., Etiology of VVR is unclear with a few predisposing factors being implicated: Obesity with tightly opposed large labia majora which prevent passage of urine, abnormal toileting position with voiding with legs apposed tightly, adhesions of labia minora, ureteral duplication or ectopic ureter with insertion into vagina, female hypospadias, spastic pelvic floor muscles due to functional disorder or cerebral palsy. VVR is rarely encountered in radiological literature because of it predominantly being a clinical diagnosis. Treatment is behavioral therapy with a voiding retraining program.
