A urachal diverticulum (also vesicourachal diverticulum) is a congenital disorder caused by the partial persistence of the allantois. The allantois, which later becomes the urachus , connects an embryo's bladder to the yolk sac .
Urachal fistula: there is free communication between the bladder and umbilicus; Urachal diverticulum (vesicourachal diverticulum): the bladder exhibits outpouching [5] Urachal sinus: the pouch opens toward the umbilicus [6] The urachus is also subject to neoplasia. Urachal adenocarcinoma is histologically similar to adenocarcinoma of the bowel ...
A urachal fistula is a congenital disorder caused by the persistence of the allantois (later, urachus), the structure that connects an embryo's bladder to the yolk sac. Normally, the urachus closes off to become the median umbilical ligament ; however, if it remains open, urine can drain from the bladder to an opening by the umbilicus .
The allantois (/ ə ˈ l æ n t oʊ ɪ s / a-LAN-toe-iss; [1] pl.: allantoides or allantoises) is one the extraembryonic membranes arising from the yolk sac.It is a hollow sac-like structure filled with clear fluid that forms part of the developing conceptus in an amniote that helps the embryo exchange gases and handle liquid waste.
The genitourinary system, or urogenital system, are the sex organs of the reproductive system and the organs of the urinary system. [1] These are grouped together because of their proximity to each other, their common embryological origin and the use of common pathways.
Generally, diseases outlined within the ICD-10 codes Q60-Q64 within Chapter XVII: Congenital malformations, deformations and chromosomal abnormalities should be included in this category. Wikimedia Commons has media related to Congenital diseases and disorders of urinary system .
Disappointed with the outcome and felt we were one of the 12 best teams in the country. We had an extremely challenging schedule and recognize there were two games in particular that we did not ...
Teratology is the study of abnormalities of physiological development in organisms during their life span. It is a sub-discipline in medical genetics which focuses on the classification of congenital abnormalities in dysmorphology caused by teratogens.
