Combination of posterior urethral valves and urachus remnants has been described as rare occurrence. We report a case of a baby boy with normal antenatal scans, in whom the presence of large urachal cyst and posterior urethral valves causing high pressure bladder and chronic kidney disease was found. The patient underwent ablation of posterior urethral valves at 23 days of life and urachal cyst removal at age of 4 and a half months.

Review
The urachus is a canal between the allantois and the early fetal bladder. Urachal carcinoma is a rare and aggressive type of bladder cancer. This cancer usually presents at an advanced stage. We report a 70-year-old patient with malignant transformation of urachal cyst several years later. The patient was treated with partial cystectomy and adjuvant radiotherapy. A review of the published literature is also presented.

Vitellointestinal duct anomalies, although one of the most frequent malformations to be found (2%-3% in population), they are most unlikely to cause symptoms. A persistent Vitellointestinal duct can induce abdominal pain, bowel obstruction, intestinal haemorrhage and umbilical sinus, fistula or hernia which commonly occurs in children. Patent vitellointestinal duct or persistent omphalomesenteric duct is a very unusual congenital anomaly which occurs in 2% of the population related to the embryonic yolk stalk. Similarly, urachal anomalies remain a rare finding, with the most common being a cyst or sinus followed by patent urachus and rarely a urachal diverticulum. Presenting symptoms include periumbilical discharge, pain and a palpable mass.Here, we report a case of an adult patient with patent vitellointestinal duct and urachus identified intraoperatively on diagnostic laparoscopy when being operated for umbilical hernia repair.

A 41-year-old woman presented to the emergency department with pain in her abdomen during menstruation. On examination, we detected a cystic lump in the midline, just below the umbilicus. Ultrasonography of the whole abdomen was suggestive of uterine fibroids with a probable mesenteric cyst. Computed tomography of the abdomen confirmed an otherwise asymptomatic, silent, urachal cyst connected to the umbilicus and urinary bladder by obliterated bands. The cyst was explored and removed surgically under combined spinal-epidural anesthesia, following a single-staged approach. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was subsequently performed. Urachal cysts are rare congenital anomalies. Any unexpected finding on clinical examination should alert clinicians for further evaluation and treatment.

We report the case of a 16-year-old girl who complained of stomach discomfort. She's been on medical therapy for roughly 6 months after being diagnosed with Crohn's disease. Magnetic resonance enterography confirmed the diagnosis of an infected urachal cyst, and she eventually had surgery. The removed material had a significant chronic inflammatory and foreign body type granulomatous response, according to histology. Because urachal cyst is an uncommon disease, early identification requires a high level of suspicion, and urachal cyst should be included in the differential diagnosis.

An allantoic cyst is a rare malformation with a frequency of 3 in 1,000,000 that may be seen antenatally by ultrasound assessment when the connection between the cloaca (future bladder) and the allantois fails to regress. A patent urachus that presents as a cyst (allantoic) is usually considered not to be associated with chromosomal abnormalities, but if it is not repaired after birth this leads to complications such as urinary tract infections and stone formation. We present a case of a fetus diagnosed with allantoic cyst at the first trimester ultrasound assessment at 12 weeks gestation. The follow up scans showed a decrease in size of the allantoic cyst with no other obvious major defects and, when invasive testing (amniocentesis with microarray analysis) was performed, a rare microdeletion, 1q21.1q21.2 was identified (1.82 Mb deletion).

The urachus is a remnant of the allantois. Failure to obliterate can result in one of four anomalies, urachal cyst being most common. Urachal cysts are relatively rare, especially in adults. This paper presents a patient with an umbilical hernia and a ruptured urachal cyst. A 39-year-old male presented with concern for umbilical hernia, but he also noted drainage. Computed tomography scan showed a urachal cyst and umbilical hernia. The urachal cyst was excised and umbilical hernia closed primarily. The incidence of an urachal cyst is unknown, but persists in roughly 2% of adults. Diagnosis is with ultrasound or CT scan. Management is excision due to risk of urachal carcinoma, which is present in over 50% of specimens. Review of literature did not reveal any other cases of a patient with both an urachal cyst and an umbilical hernia, thus making this case a unique presentation for this condition.

Abdominal pain is a common cause of emergency department visits. It often poses a diagnostic challenge for physicians given the broad spectrum of its possible medical and surgical etiologies. We report the case of a 32-year-old man who presented to the emergency department with a complaint of lower abdominal pain for one week. Abdominal examination revealed suprapubic mass and tenderness. Laboratory investigation revealed elevated leukocyte count and inflammatory markers. An abdominal ultrasound examination showed a collection with poorly defined borders. Additionally, CT demonstrated a soft tissue mass adjacent to the anterior abdominal wall with an upward track to the umbilicus, conferring the diagnosis of a urachal abscess. The patient underwent successful management of the abscess with surgical excision. This case highlights the importance for clinicians to be aware of congenital urachal anomalies since early recognition of the urachal cyst is essential to determine the proper surgical management.

OBJECTIVE
We report the first case in which the onset of omphalocele was after the spontaneous rupture of an allantoic cyst. We hypothesize a causal link between the spontaneous rupture of the cyst and the herniation of the viscera. . A 36-year-old woman was diagnosed with an allantoic cyst during the first trimester. The allantoic cyst underwent spontaneous rupture during the 32nd week of gestation, and an omphalocele developed secondary to the cyst's rupture. Two days after birth, the peritoneum covering intestinal loops broke spontaneously and the newborn underwent successful urgent surgery.
CONCLUSIONS
This case may suggest that the relative benignity of the allantoid cysts may recommend a close ultrasound follow-up in order to identify the onset of any complications, as a late third trimester onset of omphalocele. Prenatal diagnosis of such complications may allow multidisciplinary management of the pregnancy with planned cesarean section, prenatal pediatric surgery consultation, and neonatal surgery.
