Bladder outlet obstruction may be diagnosed before or after birth. The usual method of diagnosis is to perform an ultrasound, which is an imaging technique that uses a device called a transducer to provide an internal picture of the body’s organs. An ultrasound can show enlarged kidneys or bladders in babies.
Your doctor may also ask you to undertake the procedure of amniocentesis. This is a procedure in which some amniotic fluid (the protective fluid surrounding a foetus) is removed from the mother’s womb for testing. A thin needle is inserted through the abdomen to obtain a small amount of amniotic fluid, which is then analyzed to show whether the baby has any birth defects such as damaged lungs or kidneys.
Complete blood count (CBC): One or more parameters related to red blood cells, white blood cells and platelets might be affected in this condition, giving a clue towards etiology and further diagnostic approach. Therefore, it is an ancillary test in the diagnostic workup of this disease.
Disclaimer: Kindly consult your physician before getting the above-mentioned tests.
