The urachus is a tubular structure that is apparent on the third week and connects the ventral cloaca to the yolk sac, as a progression from the allantois. Following the normal regression procedure, the urachus remains as the median umbilical ligament. Urachal remnants are present in 1.03% of paediatric patients while in 92.5% of cases represent incidental findings. Urachal anomalies are classified in four types as patent urachus (50-52%), urachal sinus (15%), urachal cyst (30%) and urachal diverticulum (3-5%). Ultrasound scan is the most commonly performed diagnostic imaging study. In case of symptomatic urachal remnants, surgical excision is indicated. Asymptomatic urachal remnants that are diagnosed at the neonatal period or early infancy should be watched up to 6 months of age, as they are likely to resolve. In persistent or symptomatic urachal remnants there is a risk of inflammation or even malignancy development, therefore we believe that there is indication for preventive surgical excision that may be performed either open or laparoscopically or by robot-assisted laparoscopy.

Clinical Laboratory Dec 2023Urachal remnants (URs) represent uncommon and underdiagnosed entities that are usually detected incidentally at imaging or present clinically different manifestations.
BACKGROUND
Urachal remnants (URs) represent uncommon and underdiagnosed entities that are usually detected incidentally at imaging or present clinically different manifestations.
METHODS
Here we presented a boy with UR infection. Ultrasonography and bacterial culture and identification were performed. He received antibiotic treatment and underwent surgical excision of the cyst.
RESULTS
The patient presented with both a urachal cyst and umbilical-urachal sinus. UR infection was caused by Actinomyces turicensis. He recovered well from the operation without complications.
CONCLUSIONS
The present case reminds clinicians to be familiar with imaging features of different types of URs and their potential complications and indicates the necessity of pathogenic microorganism analysis to tailor antibiotic treatment and post-operative follow-up to prevent complications.

INTRODUCTION AND IMPORTANCE
Urachal cyst infections during pregnancy are exceptionally rare, posing diagnostic challenges. This case report contributes to the limited literature, emphasizing the rarity, diagnostic difficulties, and the need for heightened healthcare provider awareness for timely intervention.
PRESENTATION OF CASE
A 32-year-old pregnant woman with persistent pelvic pain, fever, and urinary symptoms sought care with inconclusive initial diagnoses despite multiple ER visits. Labor revealed a palpable mass, and postpartum, a CT scan identified a urachal cyst abscess. Urgent laparoscopy confirmed peritonitis, leading to cyst removal, antibiotics, and a subsequent laparotomy. Histology confirmed an abscessed urachal cyst.
DISCUSSION
Urachal cyst infections in pregnancy, exceptionally rare and diagnostically challenging, highlight the importance of considering them in abdominal pain differentials. Diagnostic tools, such as ultrasound and CT scans, can be misleading, emphasizing the necessity for a multidisciplinary approach.
CONCLUSION
This case report underscores the challenges in diagnosing and managing an infected urachal cyst during pregnancy, stressing the need for awareness and a comprehensive diagnostic approach for optimal outcomes. The rarity of such cases warrants increased attention within the medical community.

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.

INTRODUCTION
Persistence of embryonic urachal structures due to a failure of the urachus to involute into the median umbilical ligament is known as a urachal anomaly (UA). UAs may remain asymptomatic or lead to abdominal pain and recurrent infections. Management of UAs in pediatric patients has historically lacked a clear consensus between conservative and surgical management. While both urologists and general surgeons manage this pathology, a comparison of management style and outcomes between these specialties has not been published to our knowledge.
OBJECTIVE
To (1) evaluate trends in management of UAs among pediatric urologists and general surgeons across three tertiary care children's hospitals and (2) identify factors that place patients at higher risk for requiring surgery.
STUDY DESIGN
All patients diagnosed with a UA from 2016 to 2020 at our multi-site institution were identified by ICD-10 code Q64.4 "malformation of the urachus" and retrospectively reviewed. Patient demographics, treatment specialty, remnant subtype, and management strategy were recorded. Data was dichotomized between both urology and general surgery as well as between surgical and nonsurgical intervention to identify and compare management strategies.
RESULTS
Overall, 143 patients diagnosed with UAs were identified. Of these patients, 74 were treated by urology and 69 were treated by general surgery. Patients who were treated by urology were significantly more likely to receive conservative treatment (66.2% treated conservatively vs. 33.8% treated surgically), while patients treated by general surgery were significantly more likely to undergo surgery (84.1% treated surgically vs. 15.9% treated conservatively, p < .0001). Though, urology was more likely to treat patients who presented incidentally (p < .01), and general surgery was more likely to treat patients who presented with an infected remnant (p < .01). Patients of male sex were more likely overall to receive surgery compared to female patients (p < .01).
DISCUSSION
Management of UAs by urologists was more conservative than general surgeons. However, both specialties treat distinctly different patient presentations, with urology managing more incidental remnants and general surgery operating on more emergent, infected urachi. Limitations of the study included its retrospective nature and the insufficient reporting of urachal remnant subtypes and presence of infection among patients.
CONCLUSIONS
Management strategies of UAs differ among urology and general surgery, but surgical and conservative treatments are necessary to appropriately treat their distinct patient populations. This study provides valuable insight into current practices of UA management and may help to inform future treatment.

Mucinous cystic tumors of low malignant potential (MCTLMP) are rare urachal neoplasms. The morphological characteristics and clinical prognosis of MCTLMP is similar to that of mucinous cystic tumors occurring in the ovary and appendix. After complete resection, almost no cases of recurrence or metastasis have been reported. Because MCTLMP is rare, it may be missed in the clinic. MCTLMP can lead to the formation of pseudomyxoma peritonei (PMP), which manifests as the widespread production of mucus in the abdominal cavity and makes the disease complex or difficult to diagnose. At present, only 3 cases of MCTLMP with PMP have been reported in the literature. In the present study a fourth case of urachal MCTLMP in a 74-year-old male that resulted in widespread PMP is presented. Initially, a multilocular cystic lesion was revealed in the urachal duct area at the anterior upper margin of the bladder after a patient, experiencing lower abdominal pain, was imaged. As revealed using light microscopy, the cyst was lined with a mucous columnar epithelium, and part of the epithelium indicated pseudolamellar hyperplasia and papillary structures. The cells indicated mild atypia and low mitotic activity. There was no stromal infiltration of tumor cells, and a large amount of mucous exudate was observed. As preoperative computed tomography examination suggested the presence of a large amount of ascites and there were increased levels of blood tumor markers, carcinoembryonic antigen and carbohydrate antigen 125, clinicians considered that the diagnosis maybe a malignant tumor of the urachal gland with peripheral dissemination. However, the diagnosis of MCTLMP with PMP was confirmed by histopathological examination. The mass was completely removed, along with part of the peritoneum and bladder wall as these were within the tumor margin. The appendix appeared normal during surgery. A one off dose of intraperitoneal infusion chemotherapy with 1,000 mg 5-fluorouracil was performed after surgery. No recurrence was observed during the 8-month follow-up period.

Intrauterine devices (IUDs) are an effective method of contraception, with failure rates comparable to sterilization. In rare cases, IUDs can migrate to other sites, including the bladder, cecum, and fallopian tubes. This case reports a 44-year-old woman who was misdiagnosed with a urachal cyst due to the migration of her IUD into the anterior abdominal wall. A laparoscopic retrieval was successfully performed. To prevent any further serious complications, it is imperative to promptly diagnose and manage migrated IUDs.

Bladder urachal cysts in children are a rare form of urachal abnormality. In this paper, we present a case of atypical imaging that presented with lower abdominal pain accompanied by hematuria, resulting in the formation of both internal and external urachal cysts in a child. A 6-year-old male child presented with repeated abdominal pain over a span of 4 days. Color ultrasound and pelvic CT scans revealed a soft tissue lesion on the right anterior wall of the bladder with an unclear boundary from the bladder wall. Voiding Cystourethrography (VCUG) showed no significant abnormalities in the bladder, while routine urine testing was positive for hematuria. A cystoscopy was simultaneously performed with a laparoscopic resection of the urachal cyst. Intraoperative cystoscopy identified the intravesical lesion, which was precisely removed using a cystoscope-assisted laparoscopy. Postoperative pathology confirmed that both extravesical and intravesical lesions were consistent with a urachal cyst. No complications were observed after the operation, and no recurrence was noted during a six-month follow-up. Therefore, for urachal cysts at the bladder's end, the possibility of intravesical urachal cysts should not be excluded, especially in patients with microscopic hematuria. We recommend performing cystoscopy simultaneously with laparoscopic urachal cyst removal to avoid missing intravesical lesions.

BACKGROUND
A few cases of small omphalocele with umbilical evagination of the bladder have been reported. However, its embryology is yet to be elucidated. Only a few reports have indicated the existence of urachal anomalies and umbilical cysts related to bladder evagination. The incidence of urachal anomalies at birth is reported to be 1 in 5000-8000 live birth, and urachal aplasia is rare. Herein, we report a rare, novel case of urachal aplasia.
CASE PRESENTATION
We encountered a small omphalocele with bladder evagination associated with urachal aplasia for which the neonate underwent surgery one day after birth. The patient was a one-day-old boy with a prenatally diagnosed omphalocele. A fetal magnetic resonance image (MRI) scan (25 weeks of gestation) revealed a 30 × 33 mm (approximately 1.3 in.) cystic lesion which was suspected to be an umbilical cyst. The baby was born vaginally at 38 weeks, weighing 2956 g. An omphalocele (hernial orifice diameter, 4 cm × 3 cm) with bladder prolapse was recognized. After sac excision, the prolapsed bladder was resected and closed with two-layer sutures. In order to secure sufficient bladder capacity, we estimated the minimum residual volume as 21 ml after bladder plasty. The remaining bladder capacity was confirmed to be 30 ml by injecting a contrast dye and saline into the bladder. The neonate had no associated cardiac urogenital or skeletal anomalies. Postoperative course was uneventful. The patient was regularly followed up for two years after surgery and underwent umbilicoplasty. He had no trouble with urinary function.
CONCLUSION
In this case, we experienced extremely rare condition of a small omphalocele with bladder evagination associated with urachal aplasia and reviewed 7 case reports of anomalies similar to those in the present case. Umbilical cord cysts may be an informative indicator of these symptoms in utero. Therefore, ultrasonography scans should be conducted until delivery, despite the spontaneous disappearance of cord cysts.
