“…The lumen of the urachus is normally obliterated during the fi h or sixth month of embryonic development and becomes the median umbilical ligament which lies in the space of Retzius, between the transversalis fascia anteriorly and the peritoneum posteriorly.There are four main variants: urachal cyst, urachal sinus, urachal diver culum and patent urachus. Among all patent urachus is rare(10%) and is presented as the most severe form 1,2 . This is the fi rst case report of bladder prolapse through a patent urachus in Nepal.…”

We report a case of bladder prolapse through a patent urachus in a term male neonate with a large, red, tubular, mucosa lined mass inferior to the umbilical cord. A cystic mass communicating with fetal urinary bladder was detected in an antenatal ultrasound in a 26 years primigravida at 18 and 26 weeks gestation. The cyst disappeared at 35 weeks and a new solid mass was noted at the fetal abdominal wall. After birth a protruded mucosal mass inferior to the umbilical cord was noted. Urethral catherisation confirmed communication with bladder. On the second day of life excision of urachus, repair, reduction of bladder and reconstruction of abdominal wall was performed. The patient voided well and was discharged on ninth day without any complication.

“…In 1 previously reported case [2], the fetal bladder became invisible on ultrasonography similar to our case; this suggests a connection between the cystic lesion and the fetal bladder. In previously reported cases of vesicoallantoic cyst which did not disappear at the time of labor, in only 1 case was the infant delivered vaginally [9]; in the remaining cases, cesarean section was selected for delivery [2,4,5,8,10,11] (table 1). We selected vaginal delivery because the ruptured cyst in the umbilical cord would not impede delivery.…”

A Case of Fetal Vesicoallantoic Cyst in the Umbilical Cord

A vesicoallantoic cyst in the umbilical cord was detected by fetal ultrasonography at 16 weeks of gestation. The blood flow through the umbilical vessels was evaluated with periodic color Doppler ultrasonographic examinations because compression by the cyst may cause reduction in blood flow and lead to fetal death. After disappearance of the cyst, the infant was delivered vaginally. Retrograde cystography revealed a narrow channel between the bladder and the navel, confirming patent urachus, which was resected without any complications.

We present a unique case of umbilical cord cysts of allantoic and omphalomesenteric remnants with progressive cord edema during pregnancy. Enlargement of the umbilical cord was observed initially at 28 weeks’ gestation; the cord cysts were first recognized at 17 weeks. At 37 weeks, a cesarean section was performed and a male infant weighing 2,300 g was delivered. The entire length of the umbilical cord was 80 cm; the 50-cm proximal portion was strikingly edematous and was 7 cm in diameter. On the 1st day of life, operative exploration was undertaken via an infraumbilical incision. It was evident that a patent urachus protruded from the bladder. The lesion was excised and the bladder was closed in a two-layer anastomosis. Histologically, the intestinal epithelium was connected to the transitional epithelium at the top of the urachus, indicating allantoic remnants fused with omphalomesenteric remnants. Such a case has not been reported previously. It was considered that the overflow of urine from allantoic remnants to omphalomesenteric remnants caused the extraordinary edema of the umbilical matrix. Based on our experience, finding progressive umbilical cord edema may indicate a patent urachus co-existing with allantoic and omphalomesenteric remnants.
