The number of women who have experienced catastrophic side effects from a medical device used to treat prolapse after childbirth is likely to be higher than expected, experts fear.
A Victorian health consumer group has conducted the first comprehensive survey of Australian women who have been treated with transvaginal mesh implants.
The Health Issues Centre says it has received more than 1,850 responses in just six weeks, with more than 750 women saying they have had adverse effects.
Prolapse is commonly a side effect of child birth, and involves the bladder, uterus or bowel collapsing into the vagina.
Women around the country have reported experiencing problems from the device including incontinence, severe chronic pain, problems walking, painful intercourse and even marital breakdown.
International studies have found as many as 36 per cent of women had side effects after having mesh implanted for prolapse.
The exact number of mesh implants used in Australia is not clear, or how many women have had side effects.
The Therapeutic Goods Administration has received reports of side effects in almost 250 patients since 2000.
It found complications were closely linked to the skill and training of the surgeon and whether the procedure was suitable for the patient.
The Australian Commission on Safety and Quality in Health Care is now reviewing the use of the implants.
It will examine whether there needs to be better training and credentialing of clinicians who implant and remove the devices.
It will also advise doctors on how to identify which patients are more likely to benefit from mesh and what patients need to be told about their treatment.
