An Infected Urachal Cyst in a 4-Year-Old Girl Presenting with Recurrent Abdominal Pain.

BACKGROUND: Urachal cysts are remnants of urachal ducts and usually present when they get infected or undergo malignant transformation. CASE REPORT: A 4-year-old girl presented to the Emergency Department (ED) with intermittent abdominal pain, fever, dysuria, and umbilical swelling. She was diagnosed with an abscess related to an infected urachal cyst by ultrasound. The patient was treated with antibiotics, and the abscess was drained by Interventional Radiology with ultrasound guidance. She recovered uneventfully and was discharged home. The urachal cyst was excised a month later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Though urachal cysts are rare, it is important to consider this entity in the differential diagnosis of acute abdomen and recurrent abdominal pain in the ED setting.

Sonographic detection of an infected maternal urachal cyst during pregnancy.

Infection of a maternal urachal cyst during pregnancy is rare; Sonography is an important diagnostic tool that can help minimize maternal and fetal complications. We describe the case of a 35-year-old multiparous woman presenting in the third trimester with 2 weeks of fever, abdominal pain, and urinary symptoms. Imaging showed a 5-cm complex anterior midline mass, found intraoperatively to be eroding into the uterus. Sonographic imaging aided in the diagnosis and management of the urachal cyst, and antepartum sonographic measurements of the lower uterine segment helped to counsel regarding a trial of labor. Following treatment, the patient stabilized and had an uncomplicated vaginal delivery.

A case report of urachal abscess: a rare differential in adult abdominal pain.

A 59-year-old woman presents with decreased appetite and abdominal pain. Her symptoms lead to lethargy and weakness. Abdominal pain is a common presentation in the primary care and emergency room setting. She was initially diagnosed with an abscess and treated with antibiotics and drainage. Upon further evaluation and cystoscopy she was discovered to have a urachal cyst. Urachal cysts are extremely rare and even more uncommon in adults, as it is usually diagnosed in children. It is an important diagnosis not to miss in the differential of adult abdominal pain as surgical intervention is often necessary for treatment. This case highlights urachal cyst as a rare and serious differential of adult abdominal pain.

Treatment of infected urachal cysts.

The urachus is a fibrous cord that arises from the anterior bladder wall and extends cranially to the umbilicus. Traditionally, infection has been treated using a two-stage procedure that includes an initial incision and drainage which is then followed by elective excision. More recently, it has been suggested that a single-stage excision with improved antibiotics is a safe option. Thus, we intended to compare the effects of the two-stage procedure and the single-stage excision. We performed a retrospective review on nine patients treated between May 1990 and September 2005. The methods used in diagnosis were ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), and cystoscopy. The study group was comprised of three males and six females with a mean age of 28.2 years (with a range from three to 71 years). Symptoms consisted of abdominal pain, abdominal mass, fever, and dysuria. The primary incision and drainage followed by a urachal remnant excision with a bladder cuff excision (two-stage procedure) was performed in four patients. The mean postoperative hospitalization lasted 5.8 days (with a range of three to seven days), and there were no reported complications. A primary excision of the infected urachal cyst and bladder cuff (single-stage excision) was performed in the other five patients. These patients had a mean postoperative hospitalization time of 9.2 days (with a range of four to 15 days), and complications included an enterocutaneous fistula, which required additional operative treatment. The best method of treating an infected urachal cyst remains a matter of debate. However, based on our results, the two-stage procedure is associated with a shorter hospital stay and no complications. Thus, when infection is extensive and severe, we suggest that the two-stage procedure offers a more effective treatment option.

Peritonitis due to intraperitoneal perforation of infected urachal cysts.

Acute bacterial peritonitis due to intraperitoneal perforation of an infected urachal cyst represents a potentially lethal complication of the rare anomalies of the fetal urachus. We report four cases of this disease, including what we believe is the first to have been correctly diagnosed prior to operation. All four patients underwent emergency laparotomy and curative excision of the urachal remnant. Review of our four cases plus seven previously reported cases disclosed the perforated urachal cyst to be predominantly a disease of young males who initially have acute peritonitis but often without specific indication of a urachal anomaly. Bacteriologic examination has identified a wide variety of infecting organisms. Umbilical sinography or abdominal ultrasonography may allow accurate preoperative diagnosis. Broad-spectrum antibiotic coverage and laparotomy are indicated and excision of the entire urachal remnant is consistently curative.

Urachal abscesses: protean manifestations, their recognition, and management.

We present the manifestations, their recognition, and treatment of urachal disorders, as well as report on 3 cases of urachal abscess in children. A review of the English literature is included.

Advances in the management of infected urachal cysts.

Persistent urachal remnants are uncommon congenital anomalies. Unless an umbilical fistula exists, infection may be the first indication of this abnormality. Five children received initial treatment for this problem at the Children's Hospital of Buffalo during a 20-year period, 1964 to 1984, and a sixth was seen secondarily. There were four boys and two girls; their ages ranged from 8 months to 9 years. Lower abdominal mass with fever and local tenderness were the most common presenting signs. Ultrasound was the most accurate study, correctly diagnosing the cyst in both patients so examined. Incision and drainage alone was performed in one patient. The other five were managed with antibiotic therapy and complete excision as the primary procedure. Cultures were obtained in five patients and were positive in four, growing Staphylococcus aureus in three and Escherichia coli in one. Significant genitourinary abnormalities were discovered in four of the five patients evaluated. It is concluded that the previously recommended therapy of incision and drainage followed by delayed resection was developed in the preantibiotic era to minimize the mortality from sepsis and the morbidity from recurrence. Our experience indicates that the use of appropriate antibiotics followed promptly by complete cyst excision as a primary procedure is both possible and safe in most cases. Furthermore, the large number of associated genitourinary abnormalities suggests that a complete work-up for these conditions should be performed.

Acute presentation of infected urachal cysts: case report and review of diagnosis and therapeutic interventions.

Urachal remnants, although relatively rare, masquerade as a large number of diverse disorders leading to a high rate of misdiagnosis. A typical case is reported in which a 10-year-old boy presented to the Emergency Department twice before being incorrectly diagnosed with a pelvic or lower abdominal periappendiceal abscess. Definitive diagnosis and treatment of an infected urachal cyst were made intraoperatively. A review and discussion of urachal remnants is presented, and a diagnostic algorithm and treatment plan is offered for this entity.

The authors report a case of acute peritonitis due to intraperitoneal perforation of an infected urachal cyst. A review of the literature found only 15 similar cases. The presence of a lower midline mass, an umbilical discharge together with ultrasound examination should suggest the possibility of urachal pathology, especially and urachal cyst, with subsequent surgical treatment.

A case of infected urachal cyst in a 42 years old women is described. Cystography shows the spontaneous drainage to the bladder through the vesical extremity of the urachus. Review of the Literature is included.

Tuberculosis of the urachal cyst.

Urachal cysts are uncommon. Rarely, these cysts can become infected. Tuberculosis of the urachal cyst is exceedingly rare, with only one case reported previously in the English language literature. Here we report the case of a 23-year-old male who presented with an infra-umbilical mass that turned out to be tuberculosis of the urachal cyst.

[Pyo-urachal cyst]. / Quiste piouracal.

A case of infected and suppurating pyourachal cyst is described. The rarity of urachal pathology in the adult prompted us to report the present case. The clinical features, diagnosis and treatment of this urachal complication are discussed.

The infected urachal cyst: primary excision versus a staged approach.

PURPOSE: We compared outcomes following single or 2-stage repair of infected urachal cysts in the pediatric population. MATERIALS AND METHODS: We reviewed the records of 17 patients 1 day to 14 years old (median age 22 months) with a urachal cyst. Immediate cyst excision was performed in 6 patients without infection, while those with an abscess underwent single or 2-stage repair. RESULTS: Median postoperative hospital stay for the urachal abscess group was 14 and 11.5 days for single and 2-stage procedures, respectively. After immediate excision postoperative complications developed in each case, although none occurred with a 2-stage approach. CONCLUSIONS: In the absence of infection, urachal cyst excision affords the most benign postoperative course. However, when infection is present, perioperative drainage with subsequent total excision, including a cuff of bladder, may offer the most effective surgical option.

Acute peritonitis caused by intraperitoneal rupture of an infected urachal cyst: report of a case.

Embryologically, the urachus is the tubular structure that connects the dome of the bladder to the umbilicus. Incomplete obliteration of the urachal lumen results in several anomalies. The most common urachal abnormality is the urachal cyst and, while intraperitoneal rupture of an infected urachal cyst is very rare, acute peritonitis resulting from intraperitoneal rupture is the most dangerous of all complications associated with urachal anomalies. We report the case of an 80-year-old woman who underwent an emergency laparotomy for lower abdominal pain and signs of acute peritonitis, which revealed intraperitoneal rupture of an infected urachal cyst. Infected urachal cysts with intraperitoneal rupture are often misdiagnosed as a common acute abdomen and result in emergency exploratory laparotomy. These patients should be managed by complete excision of the urachal remnant to prevent any malignant change occurring, as malignant changes have been reported.
