Univariate analysis indicated that seven parameters difered signiicantly between the two groups. Binary logistic regression analyses showed that the rate of gross hematuria was signiicantly higher(P = 0.042, Exp[B] = 7.889) and the rate of fatty iniltration of the Retzius space was signiicantly lower(P = 0.006, Exp[B] = 0.028) in patients with urachal carcinoma than in those with benign urachal masses. Gross hematuria and fatty iniltration of the Retzius space may be indications of malignant and benign urachal masses, respectively.展开更多

Methods: Seven cases of urachal carcinoma in the bladder were analyzed retrospectively. Results: All the tumors were found locating in the dome of bladder. Of them, 4 were mucinous adenocarcinoma, one was well differentiated papillary enteric adenocarcinoma, one was well differentiated squamous carcinoma, and one was neuroendocrine carcinoma. Cystomorphous urachal remnants were found in 4 cases. The main complaint was hematuria and all patients underwent partial excision of bladder and urachus. Conclusion: Mucinous adeno-carcinoma is the main histo-pathological type, and cystomorphous urachal remnants are often accompanied with urachal carcinoma in the bladder. The key diagnostic criteria of urachal carcinoma in bladder are site and histopathology. And to examine the specimens carefully to find the urachal remnants is important.展开更多
