Women and ESRD: modalities, survival, unique considerations

Women currently constitute 44.3% of prevalent patients on hemodialysis and 47% of those on peritoneal dialysis. Women on dialysis do not experience the survival benefit seen in those not on dialysis. This loss of a survival advantage is partially related to a lower cardiovascular survival benefit along with a higher noncardiovascular mortality rate compared with their male counterparts. Of particular concern is the markedly higher mortality rates seen in women less than 45 years of age on dialysis. There are several female hormonal abnormalities in the female dialysis patient that can result in menstrual irregularities, anovulation, infertility, sexual dysfunction, early menopause, accelerated bone loss, and potentially increased risk of cardiovascular complications. Although fertility is impaired in dialysis, conception occurs in 1% to 7% of women of childbearing years on dialysis. Hence, all women with a potential for pregnancy should be counseled regarding the risks of pregnancy and contraceptive options. There are specific gynecologic considerations unique to peritoneal dialysis, including hemoperitoneum, decreased fertility, and uterine prolapse. Sexual dysfunction is commonly seen in the female dialysis population and is associated with depression and a lower quality of life; however, despite the high prevalence, it is generally not assessed nor is it treated. Depression is also common in the female dialysis population. Like sexual dysfunction, depression is underdiagnosed and undertreated in this population.
