The urachus is a tubular structure that is apparent on the third week and connects the ventral cloaca to the yolk sac, as a progression from the allantois. Following the normal regression procedure, the urachus remains as the median umbilical ligament. Urachal remnants are present in 1.03% of paediatric patients while in 92.5% of cases represent incidental findings. Urachal anomalies are classified in four types as patent urachus (50-52%), urachal sinus (15%), urachal cyst (30%) and urachal diverticulum (3-5%). Ultrasound scan is the most commonly performed diagnostic imaging study. In case of symptomatic urachal remnants, surgical excision is indicated. Asymptomatic urachal remnants that are diagnosed at the neonatal period or early infancy should be watched up to 6 months of age, as they are likely to resolve. In persistent or symptomatic urachal remnants there is a risk of inflammation or even malignancy development, therefore we believe that there is indication for preventive surgical excision that may be performed either open or laparoscopically or by robot-assisted laparoscopy.

An 11-day-old, captive-born, male prehensile-tailed skink (Corucia zebrata) was evaluated for a chronically swollen umbilicus. On presentation, the skink appeared dehydrated and weak. The umbilical stump was sensitive, edematous, and erythematous. Yellow fluid was readily expressed during palpation of the surrounding area, suggestive of urine. Following several days of supportive care, a positive contrast cloacagram supported the diagnosis of a patent urachus. An exploratory celiotomy was performed, confirming yolk coelomitis and a patent urachus. Both were corrected surgically, and the skink improved steadily thereafter. This report confirms the presence of a urinary bladder in C. zebrata and is the first report of a patent urachus in a reptile. Surgical intervention and medical management of concurrent infectious coelomitis were curative in this case.

We report 2 cases of patent urachus with bladder prolapse, which has a characteristic finding of "disappearance of cyst" antenatally. In the first case, a 34-year-old woman presented at 14 weeks gestation for evaluation of a cyst. Prenatal ultrasonography revealed a cystic mass at the base of the umbilical cord, communicating with the bladder. At 26 weeks gestation, the cyst had disappeared, and a solid mass bulged out inferior to the umbilical cord. At term, the patient delivered a male infant. Examination of the neonate demonstrated mucosal protrusion inferior to the umbilical cord. Catheterization confirmed communication with the bladder. We diagnosed patent urachus with bladder prolapse. In the second case, a 36-year-old woman presented at 19 weeks gestation for evaluation of moderate bilateral hydronephrosis and an abdominal cyst. Prenatal ultrasonography revealed a cystic mass at the base of the umbilical cord, communicating with the bladder. At 26 weeks gestation, the cyst had disappeared. At term, the patient delivered a male infant displaying patent urachus with bladder prolapse. Understanding of the development of urachus is important for prenatal diagnosis, which in turn allows surgery immediately after birth. We showed bladder function after surgery remains good at school age.

Review
Urachal patency is an umbilical disease in newborn foals. Etiologically, either the closure of the urachus remains absent after birth (persistent urachus) or the urachus was already closed and reopens at a later time (patent urachus). The most common causes of patent urachus are congenital defects, tearing of the navel above the predilection site, trauma, increased intravesical or abdominal pressure and umbilical infections. Patent urachus occurs more frequently in premature or weak and immunocompromised foals. Colts are more often affected than fillies. Typical clinical signs are apparent immediately after birth (persistent urachus) or 7-14 days postpartum (patent urachus). These include either dripping or a stream of urine through umbilicus during micturition as well as a moist umbilical area. The diagnosis is usually unambiguous. Typical laboratory findings are not described for patent urachus. Conservative treatment such as obliteration, cauterization or cryosurgery may be employed in cases lacking an inflammation of the urachus or other umbilical structures and when the urachal lumen measures less than 6 mm. Surgical treatment is indicated in foals with large urachal lumen, an umbilical infection or sepsis as well as when no therapeutic success is attained after a conservative treatment of 5-7 days. In most cases, prognosis is good, however complications such as umbilical inflammation, disseminating infections, and secondary joint diseases may significantly impair prognosis.

The simultaneous occurrence of a Meckel's diverticulum and a patent urachus is very uncommon. We describe the occurrence and surgical treatment of Meckel's diverticulum and an urachal anomaly in a 1-year-old boy. The patient had intermittent production of clear fluid from the patent urachus, which disappeared after surgical resection.

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.

This is a case report about a patient presenting with a urachal mass mimicking a urachus adenocarcinoma. Cystoscopy showed a vesicourachal patent diverticulum. Histological findings after the removal of the umbilicus, urachus, urachal tumor, as well as a bladder cuff, consisted of a nonspecific polymorphous suppurative inflammatory infiltrate. Urachal adenocarcinoma is an aggressive tumor with poor prognosis if not treated while it is still localized. Surgical excision is the only recommended treatment that offers the best chances of survival. As no preoperative procedure has been proven accurate enough to rule out the diagnosis of adenocarcinoma, surgery appears to be inevitable.
