Review
Patent urachus is a type of urachal anomaly in which the urachus does not tail off but remains connected to the bladder in the umbilicus. The prevalence of patent urachus is very low. Herein, we report a case of patent urachus ruptured and exposed to amniotic fluid in utero. In this case, the size decreased after the second trimester, which was thought to be due to rupture in utero. After delivery, patent urachus was confirmed by inserting a foley catheter, which runs through a ruptured cyst on umbilical cord insertion. The day after delivery, the neonate underwent surgical excision of the urachal cyst and closing umbilicus. The mechanism of patent urachus rupture is unknown. As the fetus matures, it is thought that the higher intravesical pressure may affect the rupture of the cyst. Patent urachus could be ruptured in the uterus spontaneously, and surgical correction is needed. Therefore, prenatal differential diagnosis is important.

UNLABELLED
Urachus is a tubular connection between the umbilical cord and the bladder of developing foetus and tends to degenerate during perinatal period to form an impatent median umbilical ligament. Failure to degenerate results in patent canal between the bladder and the umbilicus called "patent urachus" which may lead to serious of symptoms such as umbilical discharge, dermatitis, umbilical infection, abdominal pain or recurrent urinary tract infections. The Tenckhoff catheter is a tube used to perform peritoneal dialysis that is inserted through abdominal wall into peritoneum either by open surgery, minilaparotomy, laparoscopy or needle-guidewire technique.
A CASE REPORT
A 57-years old man was admitted to the hospital after implantation of Tenckhoff catheter by percutaneous technique in order to start peritoneal dialysis treatment. His medical history was: endstage chronic kidney disease (diabetic nephropathy), type 2 diabetes and hypertension. After the infusion of dialysate the patient experienced sudden urine pressure and passed significant amount of urine. The CT scan showed the tip of catheter being placed inside the urinary bladder. The catheter was introduced through the abdominal wall into the canal of previously undiagnosed patent urachus. The decision about re-surgery was made to stitch urachal remnants and place new the Tenckhoff catheter. Awaiting the surgery patient temporary started hemodialysis. In ongoing observation patient did not present any complications associated with peritoneal dialysis treatment.

Review
An infant was born at term after having received a diagnosis of omphalacele on prenatal ultrasound scan. She did not have an omphalacele but rather had a patent urachus with bladder eversion onto the abdominal wall. The remainder of the genitourinary tract was normal, and it was possible to pass a soft catheter through the urethra and out of the evaginated bladder. The prolapse was repaired without complications, and the infant recovered uneventfully. A voiding cystourethrogram and renal ultrasound scan were normal at 2 month follow-up. The embryology and malformations of the urachus are discussed, and the rare case reports of similar anomalies are reviewed.
