Ultrasound
what is the management of fibroids?
Management: Symptom based.
For HMB +/- small fibroids - COCP, POP, Mirena
large fibroids & fertility preservation desired - Fibroid embolisation, myomectomy
submucosal fibroids - Hysteroscopic fibroid resection
Declined or failed medical treatment & fertility preservation not required - Hysterectomy (sugical rmeoval of uterus)
what is endometriosis?
