RESUMO

BACKGROUND: Urinary bladder masses in children are extremely rare. Certain benign conditions (e.g., ureterocele) can mimic malignant bladder masses. In this report, we present a unique case of a urachal cyst masquerading as a bladder malignancy. Unlike the typical location of urachal cysts along the course of the urachal tract, the cyst in this case was unexpectedly situated within the urinary bladder, leading to diagnostic difficulties. CASE PRESENTATION: A 2-year-old Bahraini boy presented with hematuria and dysuria for 2 weeks. There was no history of fever, abdominal pain, or vomiting. Physical examination yielded normal findings. Urinalysis showed numerous red blood cells and revealed positive results for nitrites and leukocyte esterase. Abdominal ultrasound showed a well-defined soft tissue lesion with internal vascularity located at the apex of the urinary bladder. Subsequently, magnetic resonance imaging demonstrated a thick-walled cystic structure arising from the anterosuperior wall of the bladder and protruding into its lumen. The patient underwent complete excision of the bladder lesion for the presumed diagnosis of rhabdomyosarcoma. Histopathological examination showed a fluid-filled space lined by stratified squamous epithelium with areas of intestinal metaplasia, revealing an unexpected diagnosis of a urachal cyst. The patient was discharged with complete resolution of symptoms. CONCLUSIONS: Intravesical urachal cysts are a rare type of congenital urachal anomaly that may simulate a bladder malignancy, particularly if associated with infection. This case emphasizes the importance of considering urachal cysts in the differential diagnosis of bladder masses, especially in children, and specifically when the lesion is midline in the anterosuperior wall of the bladder.

RESUMO

PURPOSE: It has been suggested that symptomatic UA requires surgical excision. However, the management of asymptomatic urachus is still controversial. We aimed to evaluate the clinical presentation, the efficacy of current modalities used, and postoperative pathology in patients with UA. MATERIALS AND METHODS: We have performed a retrospective review of all patients diagnosed with UA and treated surgically or conservatively over 18 years. Demographic data, clinical presentation, imaging modalities, pathology, treatment, and postoperative complications were analyzed. RESULTS: Twenty-five symptomatic patients (18 males and seven females) with a median age of 13 years (1 month to 37 years) were identified. 15 (60%) were diagnosed with a urachal cyst, 4 (16%) with sinus, 3 (12%) with urachal diverticulum, and the remaining 3 (12%) with patent urachus. Of those, 20 (80%) underwent surgical repair, and the remaining five (20%) patients were managed conservatively. 4 (20%) underwent laparotomy, 7 (35%) laparoscopic incision, and the remaining 9 (45%) laparoscopic robotic-assisted surgery. Nine patients required bladder cuff excision. The median operative time was 75 min (42-140 min). One patient developed Clavien-Dindo grade IIIA complication resulting in infected hematoma, which resolved after drainage. Another patient with a complication of grade IIIB needed reoperation as a result of recurrent events of an abscess. 13 (65%) demonstrated epithelium lining of the urachus on postoperative pathology. CONCLUSIONS: Our data show that most of the patients with UA presented with epithelial lining, which might lead to the later malignant transformation. It might cause a shift from the conservative management of asymptomatic patients to surgical intervention. Robotic-assisted surgery appears beneficial in these patients, especially when the bladder cuff excision is required.

RESUMO

Combination of posterior urethral valves and urachus remnants has been described as rare occurrence. We report a case of a baby boy with normal antenatal scans, in whom the presence of large urachal cyst and posterior urethral valves causing high pressure bladder and chronic kidney disease was found. The patient underwent ablation of posterior urethral valves at 23 days of life and urachal cyst removal at age of 4 and a half months.

RESUMO

BACKGROUND: Eosinophilic cystitis is a rare inflammatory disease of the bladder characterized by eosinophilic infiltration of the bladder wall. Most Eosinophilic cystitis cases present with mucosal lesions of the urinary bladder. We present a very rare case of large mass-forming eosinophilic cystitis, involving the inside and outside of the bladder associated with an infected urachal cyst. CASE PRESENTATION: A 59-year-old man presented with gross hematuria, fever, dysuria, and suprapubic pain. Computed tomography showed a heterogeneously enhancing mass that measured 7.6 cm × 4 cm located on the anterosuperior portion of the bladder with an internal fluid collection. Cystoscopy revealed a raspberry-like mass lesion on the bladder dome. Transurethral resection of the bladder was initially performed. The mass lesion protruding from inside the bladder was removed, and pus-like fluid was drained. The pathologic diagnosis was eosinophilic cystitis. Follow-up computed tomography showed a remnant mass outside the bladder and urachal cyst. To eliminate the remnant lesion, robot-assisted partial cystectomy was performed. The patient showed no evidence of recurrent disease on follow-up cystoscopy and computed tomography for up to 2 years. CONCLUSIONS: Clinicians should consider the possibility of eosinophilic cystitis in patients who present with hematuria, fever, and suprapubic pain and have both intravesical and extravesical masses.

RESUMO

Introduction: Meckel's diverticulum (MD), a remnant of the omphaloenteric duct, is among the most frequent intestinal malformations. Another embryonic vestige is the urachus, which obliterates, becoming the median umbilical ligament; the failure of this process can lead to a urachal cyst formation. We present a case of Meckel diverticulitis misdiagnosed as an infected urachal cyst. Presentation of case: A 16-year-old girl presented with hypogastric pain, fever and vomiting. She had undergone an appendectomy 6 years prior and no digestive malformation had been documented. In the last 2 years, she had 3 events of urinary tract infections with Escherichia coli, and anabdominal ultrasound discovered a 28/21 mm hypoechogenic preperitoneal round tumor, anterosuperior to the bladder. We established the diagnosis of an infected urachal cyst, confirmed later by magnetic resonance imaging. Intraoperative, we found MD with necrotic diverticulitis attached to the bladder dome. Discussions: Meckel's diverticulum and urachal cyst (UC) are embryonic remnants. Both conditions are usually asymptomatic, being incidentally discovered during imaging or surgery performed for other abdominal pathology. Imaging diagnosis is accurate for UC, but for MD they are low sensitivity and specificity. For UC treatment, there is a tendency to follow an algorithm related to age and symptoms, but there is no general consensus on whether to perform a routine resection of incidentally discovered MD. Conclusion: Preoperatory diagnosis of MD represents a challenge. We want to emphasize the necessity of a thorough inspection of the small bowel during all abdominal surgical interventions and MD surgical excision regardless of its macroscopic appearance. These two actions seem to be the best prophylaxis measures for MD complications and consequently to avoid emergency surgery, in which case more extensive surgical procedures on an unstable patient may be needed.

RESUMO

ABSTRACT: This case describes a 6-year-old girl who presented to the pediatric emergency department with 3 days of fever and suprapubic pain in the setting of 1 month of worsening, dull abdominal pain. On presentation, she had a tender, erythematous, and fluctuant mass on her lower abdomen. Point-of-care ultrasound was used to identify an abnormal fluid collection anterior to her bladder, suspicious for an infected urachal cyst. In this case, point-of-care ultrasound helped identify this uncommon finding in a timely fashion, which expedited definitive care and prevented unnecessary exposure to ionizing radiation.

RESUMO

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.

RESUMO

Urachal remnants are thought to have a low prevalence. However, recent studies indicate a higher rate. The aim of this study was to evaluate the prevalence of urachal remnants in children referred for imaging by abdominal/urinary/suprapubic ultrasonography in one calendar year. Files of children who underwent abdominal/urinary/suprapubic ultrasonography in one calendar year were retrospectively reviewed. Data regarding children ≤17 years that underwent ultrasonography of the ventral abdominal wall while being assessed for various reasons were collected. Anomalies detected, age, gender, reason for ultrasonography request, and diagnosis of the urachal remnant were noted. All ultrasonography assessments were performed by a single pediatric radiologist in a single institution. There were 4836 patients in the study (1919 boys). Median age of the whole cohort was 7 years. A total of 10 patients were found to have urachal remnants, which included eight urachal cysts (three boys) and two urachal diverticula (one boy).Conclusion: The prevalence of urachal remnants in our cohort was nearly 2 in every 1000 children. More specifically, the prevalence of urachal cysts was one in 600. What is Known: • Urachal remnants were believed to be rare. • Recent studies indicated a higher incidence than previous reports. What is New: • This study shows that urachal remnant may be observed in one every 500 children that undergo ultrasonography of the abdomen for various reasons. • Parental counselling and management of urachal remnants should be planned accordingly.

RESUMO

The urachus is a fibrous tube extending from the umbilicus to the anterosuperior bladder dome that usually obliterates at week 12 of gestation, becoming the median umbilical ligament. Urachal pathology occurs when there is incomplete obliteration of this channel during foetal development, resulting in the formation of a urachal cyst, patent urachus, urachal sinus or urachal diverticulum. Patients with persistent urachal remnants may be asymptomatic or present with lower abdominal or urinary tract symptoms and can develop complications. The purpose of this review is to describe imaging features of urachal remnant pathology and potential benign and malignant complications on ultrasound, CT, positron emission tomography CT and MRI.

RESUMO

INTRODUCTION: Urachal cyst is an exceptionally rare disease in children caused by the incomplete obliteration of the urachal remnant. Urachal cysts seldom cause symptoms unless a secondary infection occurs. The symptoms of an infected urachal cyst are nonspecific and may be similar to acute appendicitis or other acute abdominal conditions. However, complications attributable to a delayed diagnosis can endanger the life of a patient. PATIENT CONCERNS: A 5-year-old boy presented with a 3-day history of severe intermittent lower abdominal pain. DIAGNOSIS: Infected urachal cyst. INTERVENTIONS: The patient was treated with surgical resection of the urachus, followed by intravenous antibiotics during the hospitalization. OUTCOMES: The patient was discharged without incident 7 days after the operation. With his follow-up in our out-patient department, he recovered well without any sequelae in the 6 months post-surgery. CONCLUSION: We suggested using the abdominal echo scan to differentiate the urachal cyst because of its high sensitivity and nonradioactive characteristic, and computed tomography is a typical diagnostic tool for urachal cysts. The mainstream management of an infected urachal cyst remains surgical excision. Complete excision of urachal cysts is relatively easy in a pediatric patient and the risk of subsequent infection is low; however, patients tend to have a low, although possible, risk of potential malignant transformation over their lifetimes.

RESUMO

AIMS: This study's aim is to present the specific ultrasonography (US) findings of a series of urachus anomalies. MATERIAL AND METHODS: Seven patients with suspected urachal anomalies underwent US scanning initially prior to the surgery and the features of images were reviewed respectively. The clinical data and pathologic results were collected also. RESULTS: US successfully diagnosed urachal anomalies in 5 patients (5/7, 71.4%) and failed to diagnose in 2 patients (2/7, 28.6%). Patent urachus showed a tubule between the umbilicus and bladder; urachal sinus was a blind focal dilatation at the umbilical end, while vesicourachal diverticulum was an outpouching at the vesical end and urachal cyst was identified as an anechoic structure along the urachus. Non-enhancement in the base and centre was the distinct features of urachus carcinoma by contrastenhanced ultrasonography (CEUS). Using a high frequency probe and CEUS the diagnostic ability of US may be improved. CONCLUSION: US showed good diagnostic ability in urachal anomalies and combined with CEUS could improve the differential diagnosis.

RESUMO

AIM: We report the results of the surgical treatment of symptomatic urachal cysts. MATERIALS AND METHODS: The medical records of patients who underwent urachal cyst excision between 2012 and 2017 were reviewed retrospectively at our hospital. The age, sex, presenting complaint, method of diagnosis, average cyst diameter, surgical procedure, and postoperative complications of each patient were recorded. RESULTS: Twenty-seven patients who had urachal cyst were included in this study; 5 out of 27 patients were treated conservatively and the rest of patients were treated surgically, made up of 16 males (72%) and 6 females (28%). The average age of the patients was 7 years (range: 1-17). The most common reason for referral was abdominal pain in 12 patients (54%), discharge in 6 patients (28%), fever in 2 patients (9%), and an abdominal mass in 2 patients (9%). An ultrasound scan was performed in all patients as an initial imaging study. The average cyst diameter was 1.5 cm (range: 1-6 cm). Laparotomy was performed in 16 patients, with 6 patients undergoing laparoscopic excision. Postoperative wound infection developed in two patients. CONCLUSIONS: Patients with urachal cysts may be managed conservatively initially. However, patients who do not show any clinical and radiological signs of regression, or those who have large cysts, should undergo surgical excision through laparotomy or a laparoscopic approach.

RESUMO

OBJECTIVE: Description of rare diagnosis of patent urachus. DESIGN: 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.

RESUMO

A 26-year-old pregnant woman was diagnosed with fetal bladder prolapse following rupture of a patent urachus/urachal cyst, based on the finding of cyst disappearance with replacement with an infra-umbilical, extra-abdominal solid soft-tissue mass, mimicking bladder exstrophy. The neonatal findings confirmed the prenatal diagnosis. The baby was healthy and had a successful surgical correction. This report provides clues to differentiating ruptured bladder prolapse from bladder exstrophy as follows: (1) well-documented urachal cyst with urine-filled mass in the early gestation, (2) development of solid soft-tissue mass shortly after disappearance of the urachal cyst, and (3) no other structural abnormalities (bladder exstrophy is usually associated with abnormal genitalia, epispadias, or pubic diastasis). This study underlines the differentiation between the two entities because of the vast difference in prognosis, management, and proper counseling.

RESUMO

OBJECTIVES: To determine the ideal management of uncomplicated adult urachal remnants and to confirm if conservative management with repeated imaging is acceptable. PATIENTS AND METHODS: This is a retrospective review of clinical notes and imaging of 45 patients with a mean age of 54.6 years who had been diagnosed with urachal anomalies at a single urology tertiary centre from January 2005 to December 2016. Patients who underwent surgical intervention and findings from patients managed non-operatively, with a mean follow up of 31 months, were evaluated. RESULTS: Thirty (66.7%) patients had incidental findings, while 15 (33.3%) were symptomatic. Eight underwent excision, one underwent an incision and drainage of abscess, while 34 of the 36 remaining patients elected to undergo surveillance with repeated ultrasound imaging. Two were lost to follow-up. Malignancy was confirmed in three patients. There was interval stability of the urachal remnant in all the patients in the non-operative cohort. The small sample size, limited follow-up, and retrospective nature of the study are recognised limitations. CONCLUSIONS: It was found that simple and asymptomatic lesions can be monitored with ultrasound, but effort must be made on initial diagnosis to ensure that malignancy is excluded using CT imaging and flexible cystoscopy where possible. Long-term follow-up of this cohort is required to assess the natural history of observed urachal anomalies.
