Urachal Cyst

Cyst occurring in a persistent portion of the urachus, presenting as an extraperitoneal mass in the umbilical region. It is characterized by abdominal pain, and fever if infected. It may rupture, leading to peritonitis, or it may drain through the umbilicus.

Therapies and Procedures

1.	Cystectomy 10/01/1997 - "Resection of the urachal cysts and partial cystectomy were performed. " 07/01/1994 - "Urachal cyst containing a stone was removed and partial cystectomy was performed. " 09/01/1986 - "Complete removal of the urachal cyst with partial cystectomy was done. " 07/01/2001 - "On the twenty-third day after catheter placement, excision of the urachal cyst and partial cystectomy were performed with relative ease and without any complications." 01/01/2015 - "Normal kidney tissue from a patient with renal cancer and bladder specimens from patients undergoing ureteral reimplantation for vesicoureteral reflux or partial cystectomy for urachal cyst were examined as normal control organs. "
2.	Laparotomy 06/01/1987 - "Under anaesthesia a central abdominal mass arising from the pelvis was palpated which on proceeding to laparotomy was found to be a blood-filled urachal cyst. " 01/01/2013 - "Ultimately the diagnosis was made by laparotomy, which revealed an abscess of an urachal cyst. " 04/01/2008 - "Exploratory laparotomy revealed a urachal cyst associated with pseudomyxoma peritonei (PMP). " 01/01/2003 - "Infected urachal cysts with intraperitoneal rupture are often misdiagnosed as a common acute abdomen and result in emergency exploratory laparotomy. "
3.	Catheters 07/01/2001 - "The catheter was inserted from the subumbilicus region and the catheter tip was intended to be situated at the caudal end of the urachal cyst. " 12/01/1983 - "Treatment of infected urachal cysts with percutaneous catheter drainage is described." 07/01/2001 - "On the twenty-third day after catheter placement, excision of the urachal cyst and partial cystectomy were performed with relative ease and without any complications." 07/01/2001 - "A drainage catheter, which had multiple holes over a 10 cm length from the catheter tip, was placed in the urachal cyst. "
4.	Appendectomy 07/01/2012 - "A retrospective analysis of the laparoscopic appendectomy shows the urachal cyst and the perforation by the trocars. " 08/01/1996 - "These included eight appendiceal abnormalities (in six patients), three Meckel's diverticula, one inguinal hernia, one urachal cyst, one para-fallopian tube cyst, and one adhesion to an appendectomy stump. "
5.	Surgical Instruments (Clip) 07/01/2012 - "An adequate trocar placement would not have perforated the urachal cyst and therefore there would have been no postoperative symptoms. " 07/01/2012 - "A retrospective analysis of the laparoscopic appendectomy shows the urachal cyst and the perforation by the trocars. "
