An urachus is a remnant of allantois in embryo development constituting a connection between the dome of the bladder and umbilicus. It develops on day 16 after conception and closes during the pregnancy to form the median umbilical ligament. Patent urachus results from a failure in closing its lumen in 10-12 gestational weeks. This anomaly occurs in 1-2 babies in 100,000 births. We present the case of patent urachus. In 20 gestational weeks, a dilatation of the umbilical cord with an anechoic mass with a transverse dimension of 19 x 12 mm starting from the fetal insertion and length of 30 cm was seen on ultrasound without any other fetal and placental disorders. Histology showed cystic edema. Prenatal diagnosis of patent urachus can be difficult because this pathology may be mistaken with other, more dangerous causes of cord cysts; thus, the occurrence of cord cysts should be closely monitored.

Bladder prolapse through a patent urachus presenting as an umbilical mass in the newborn: characteristic prenatal sonographic findings and the diagnostic benefit of postnatal cystography.
Bladder prolapse through a patent urachus is rare. We present a newborn with an unusual exophytic, erythematous umbilical mass. Voiding cystography readily demonstrated continuity of the bladder dome with the umbilical mass, confirming bladder prolapse through a patent urachus. The diagnosis of bladder prolapse was rapidly made in a second newborn with similar imaging and clinical findings and confirmed by cystography. We discuss the embryology of this condition including the association with a vesico-allantoic cyst in utero. Pre- and postnatal images are presented. The use of cystography in diagnosis is emphasized.

Simultaneous presentation of omphalocele, patent urachus, and umbilical cyst is very rare. There is wide range of differential diagnosis for umbilical cyst. Accurate assessment of umbilical cysts is important to evaluate other abnormalities.

Case report.
SETTING
Department of Obstetrics and Gynecology, 2nd Faculty of Medicine and Faculty Hospital Motol Prague.
CASE REPORT
Patent urachus is a rare diagnosis, which in this case was detected prenatally by ultrasound. Involution of the urachus is not fully completed upon birth, therefore in cases of small persisting communication between the urinary bladder and the umbilicus conservative approach and waiting for spontaneous closure is usually chosen. In our case surgery treatment has chosen as a prevention of urinary infection because of patent urachus manifested as a wide communication.
CONCLUSION
This congenital defect usually manifests itself early after birth as a visible structural anomaly of the umbilicus and/or as urine leakage in the umbilicus opening area. It is important to keep in mind that urachus irregularities may be accompanied by other urinary system defects. Every child presenting with such an anomaly should therefore be thoroughly examined. If the procedure is performed by an experienced surgical team postoperative complications are uncommon and overall long-term prognosis for patients is excellent.

Review
Urinary incontinence results from disorders of the lower urinary tract or neurologic diseases either of the nerve supply to the bladder/urethra or within the central nervous system. Congenital causes include patent urachus and ectopic ureter. Coordination of lower urinary tract function involves the interaction of both the sympathetic and parasympathetic system as well as somatic branches of the central nervous system. Well-recognized causes of incontinence include equine herpes virus 1 myeloencephalopathy, polyneuritis equi (neuritis of the cauda equina), and sacral/coccygeal trauma. Idiopathic bladder paralysis is characterized by bladder paralysis and sabulous cystitis in the absence of overt neurologic deficits.

We describe our experience in 2 institutions handling bladder prolapse through a patent urachus (PU), together with a brief review of published literature. Case 1: A term neonate with congenital prolapsed bladder via PU. Ultrasound at 21 weeks gestation revealed a male fetus with a large midline pelvic cyst communicating with the bladder which disappeared on subsequent 27 weeks ultrasound. Case 2: A term female neonate with congenital prolapsed bladder via PU with no prenatal diagnosis. In both cases the bladder closure was undertaken during the newborns' first days of life.

Review
Urachal anomalies are classified into four types depending on the level of persistence of the embryonic urachal remnants between the urinary bladder and the umbilicus: patent urachus, umbilical-urachal sinus, urachal cyst, and vesico-urachal diverticulum. Due to the increasing use of cross-sectional imaging, urachal anomalies are frequently detected as incidental findings. Imaging plays a pivotal role in the initial diagnosis, evaluation of complications, treatment follow-up, and long-term surveillance of patients with urachal anomalies. Different urachal anomalies demonstrate characteristic imaging features that aid in a timely diagnosis and guide treatment. A patent urachus is visualized as an elongated tubular structure between the umbilicus and the urinary bladder. While umbilical-urachal sinus appears as focal dilatation at the umbilical end of the urachal remnant, the vesico-urachal diverticulum presents as a focal outpouching of the urinary bladder at anterosuperior aspect. Urachal cysts are identified as midline fluid-filled sacs most frequently located near the dome of the urinary bladder. Untreated urachal anomalies could progress into potential complications, including infection and malignancy. Knowledge regarding imaging features of urachal anomalies helps in timely diagnosis, treatment, follow-up, and early detection of complications.

Review
Urachal anomalies are more common than previously thought, with more cases discovered incidentally, because of the increased use of cross-sectional imaging. Although an abnormal persistence of an embryologic communication between the bladder and the umbilicus is often recognized and managed in childhood, it may persist into adulthood, with a greater risk of morbidity. Congenital urachal anomalies that are detected early can benefit from an optimized management including surgical approach with a complete resection of the urachal remnant in cases when spontaneous resolution or medical management has failed. At imaging, the different types of urachal anomalies have a distinct appearance. A patent urachus is recognized as an elongated patent connection between the bladder and the umbilicus. An umbilical-urachal sinus is depicted as a blind focal dilatation at the umbilical end, whereas a vesicourachal diverticulum is a focal outpouching at the vesical end. Urachal cysts are visualized as midline fluid-filled sacs most frequently located near the bladder dome. Complications of urachal anomalies have nonspecific clinical findings and can mimic other abdominal and pelvic processes. Potential complications, such as infection and tumors, should be recognized early to ensure optimal management. Understanding of the embryonic development of the urachus is necessary for the radiologist to diagnose the wide variety of urachal disease. RSNA, 2016.

Ingestion of foreign body may induce complications such as perforation, impaction, or penetration. Diagnosis rarely made preoperatively due to clinical symptoms are usually nonspecific and can mimic other surgical conditions. A 69-year-old male presented to emergency department with vague abdominal pain for few days. Following a clinical evaluation and computed tomography scan of the abdomen, provisional diagnosis of urachal carcinoma was made. As the result of urachal excision with partial cystectomy including fishbone were resected, pathology revealed benign urothelium.
