The choice of delivery tactics and the diagnosis of pelvic-head disproportion are the most important tasks in practical obstetrics. A high proportion of caesarean sections is associated with clinically or anatomically narrow pelvis, among other things. Failure to choose the best delivery tactics for obstructed labour can have serious consequences for both mother and foetus. Disproportion between the fetal head and the maternal pelvis and arrest of labour are indications for caesarean section in most clinical cases. Testing the anatomo-physiological capacity of the pelvis during labour is a decisive factor in determining the method of delivery. A review of the literature showed that routine pelvimetry does not have the necessary accuracy to detect clinically narrow pelvis and obliterated forms of anatomically narrow pelvis. More accurate imaging techniques are computed tomography, magnetic resonance imaging and ultrasound pelvimetry. The accuracy of the diagnostic modalities as well as the pelvimetry should be considered. The search for diagnostic methods that may predict the development of obstetric complications caused by pelvic-head disproportion in anatomically or clinically narrow pelvis is necessary.
