“…In this study, only one patient in the urachal infection group showed umbilical discharge, and this infection was secondary to patent urachus. Because both the patent urachus and umbilical-urachal sinus are connected to the umbilical cord, it is easy to understand that these two infections may be accompanied by a purulent discharge ( 15 ). And umbilical discharge may be the specific clinical presentation of urachal infection.…”

“…Painless gross hematuria is the most common symptom, and when it occurs, it usually indicates that the tumor has already invaded the bladder ( 14 ). As for urachal infection, it is more common in infants and children ( 15 ) and may produce non-specific symptoms such as abdominal pain, fever, umbilical discharge, and a palpable abdominal mass ( 16 ).…”

“…According to literature and routine clinical practice, urachal carcinoma may manifest similar clinical symptoms to the infected urachal remnants, such as abdominal pain, hematuria, dysuria, etc., or both may be asymptomatic ( 15 , 16 ). Kim et al ( 17 ) reported that the urachal carcinoma may contain cystic components, and the tumors range from solid to the mixture of solid and cystic.…”

PurposeTo explore the clinical and radiological differences between urachal carcinoma and urachal infection.MethodsClinical and imaging information for 13 cases of urachal carcinoma and 14 cases of urachal infection confirmed by pathology were retrospectively analyzed. The size, location, shape, margin, lesion composition, calcification, T1 and T2 signal intensity, peripheral lymph nodes, degree of enhancement, adjacent bladder wall, and apparent diffusion coefficient (ADC) value were examined in both groups, and distinguish features were determined. The student t-test or Mann-Whitney U test was used for quantitative data, and Fisher’s exact test was used for qualitative data. Kappa coefficient consistency test was used to evaluate the interobserver agreement.ResultsSex, hematuria, abdominal pain, calcification, and thickening of adjacent bladder wall can distinguish between urachal carcinoma and urachal infection (p < 0.05). There were no statistical differences in age (p = 0.076), size (p = 0.797), location (p = 0.440), shape (p = 0.449), margin (p = 0.449), lesion composition (p = 0.459), T1 signal intensity (p = 0.196), T2 signal intensity (p = 0.555), peripheral lymph nodes (p = 0.236), degree of enhancements (p = 0.184) and ADC value (p = 0.780) between two groups.ConclusionThe following clinical and imaging features help distinguish urachal carcinoma from urachal infection: sex, hematuria, abdominal pain, calcification, and thickening of the adjacent bladder wall.

“…The urachus is a fetal connection allowing urine to pass between the developing urinary bladder and the placenta [ 1 , 2 , 3 ]. Urachal anomalies (UA) result from failure of the urachus to undergo complete atrophy by the time of birth: at this time it should be nonfunctional and typically look like a fibrous connective tissue remnant connecting the bladder vertex with the umbilicus [ 4 , 5 ].…”

This retrospective study investigated the prevalence of different urachal anomalies (UA) in cats (n = 60) and dogs (n = 38) and their association with clinical symptoms and urinalysis alterations. Among UA, the vesicourachal diverticulum was the most prevalent UA diagnosed in both cats (96.7%) and dogs (89.5%): the intramural vesicourachal diverticulum was diagnosed in 76.7% of cats and 71.1% of dogs, followed by extramural vesicourachal diverticulum (20.0% and 18.4% respectively). In both cats and dogs, bladder wall diffuse or regional thickening was the most prevalent alteration. The most common alterations of the urinary bladder content were urolithiasis sediment in cats (33.3%) and in dogs (31.6%). Dogs with UA were more often asymptomatic (p = 0.01). No difference was found in cats. Stranguria, hematuria, and urethral obstruction were the most frequently reported clinical signs, while hematuria and leukocyturia were the most prevalent abnormalities at urinalysis. In conclusion, our study confirmed UA as uncommon, and often incidental findings, with a high prevalence of animals without clinical signs.

“…Urachal anomalies are an uncommon yet important cause of pediatric hospital presentations and can mimic many other causes of intraabdominal pathology and fever. 1 Urachal cysts occur in 1 in 5000 live births, but typically only become clinically relevant when infected. 2 Their low prevalence and variable clinical presentation often lead to a delay in diagnosis and treatment that can contribute to severe, even lifethreatening, illness because of disseminated infection.…”
