A full-term, female newborn, weighing 2.1 kg was brought to the pediatric emergency with complaints of a pinkish bulge in the lower part of the abdomen, with absent anal opening. On examination, the neonate was active and healthy looking with mild abdominal distension. There was a defect in the lower part of the abdomen with exstrophied bladder and a pale smooth swelling below it, with absent anal opening [Figure 1]a. The umbilical cord was inserted at the upper part of the exposed bladder. Both the ureteric openings could be visualized in the bladder patch, while the distal pale swelling had a pinpoint opening caudally, which discharged some whitish fluid on compressing the swelling. Another pinpoint opening was seen more distally, which had meconium on being probed with an infant feeding tube, suggestive of an anovestibular fistula (AVF) [Figure 1]b. The labia and the clitoris were divergent and no separate anal opening was seen. X-ray of the abdomen revealed wide pubic diastasis and distended rectal and sigmoid segments with no evidence of pouch colon. Ultrasound abdomen showed mild hydronephrosis of the left kidney. Baseline blood parameters were normal.

As the patient was not able to pass meconium, a cutback anoplasty was done. However, there was persistent posterior shelving of the rectum, 1 cm above the anal verge, not permitting free passage of Hegar dilators; a transverse colostomy was also performed to ensure proper bowel evacuation. Vaginal opening was enlarged, which allowed the whitish vaginal discharge to flow out freely. At present, the baby is decompressing well by stoma, started on feeds and doing well.
In general, infants with bladder exstrophy have significant widening of the pubic symphysis and anteriorly placed anus. In females, the clitoris is bifid and vagina is anteriorly placed with a stenotic opening. Exstrophy–epispadias sequence is a spectrum of disease of abdominopelvic fusion abnormality, including phallic separation with epispadias, pubic diastasis, exstrophy of the bladder, cloacal exstrophy, and OEIS complex (omphalocele, exstrophy of the cloaca, imperforate anus, and spinal defect). Our case was a variant of this sequence; exstrophy bladder, hydrocolpos with AVF. To our knowledge, this is the first report of bladder exstrophy with AVF in a female; a similar case has been reported by Singh et al. in a male neonate wherein the anus was placed as an anteriorly placed perineal fistula and anoplasty was done.
