two diameter pocket method

The two diameter pocket (TDP) method is an alternative method of assessing amniotic fluid volumes on ultrasound. However, it is not thought to be a good predictor of adverse neonatal outcome .

Sonographic assessment

According to this method :

• TDP <15 cm: indicative of oligohydramnios
• TDP 15-50 cm: usually taken as normal
• TDP >50 cm: indicative of polyhydramnios
