Blood in urine in a patient in labour, with history of previous LSCS. The diagnosis is:
In obstructed labour, the bladder becomes an abdominal organ and due to compression of urethra between the presenting pa and symphysis pubis, the patient fails to empty the bladder. The bladder walls gets traumatised which may lead to blood stained urine, a common finding in obstructed labour. The base of the bladder and urethra which are nipped in between the presenting pa and symphysis pubis may undergo pressure necrosis. Ref: Textbook of Obstetrics by DC Dutta, 6th edition, Page 405.
