This comprehensive account of obstetrics and gynaecology provides trainee specialists - particularly those preparing for the MRCOG examination or corresponding overseas examinations - as well as established specialists with an up-to-date reference. This text retains the aim of previous editions by Sir John Dewhurst: to integrate the relevant basic sciences with clinical practice. While an extensive revision has been undertaken to emphasize new advances and developments in the specialty, these are placed in perspective and related to basic clinical principles that continue to stand the test of time.
