PURPOSE: This study aimed to compare sexual dysfunction in Danish female predialysis patients with chronic kidney disease (CKD) stage 4-5 with age-matched healthy women in Denmark.

METHODS: Twenty-seven adult female predialysis patients (CKD stage 4-5 ~ creatinine clearance ≤ 30 ml/min) without diagnosed depression and 54 randomly assigned healthy female controls completed the questionnaires Female Sexual Function Index, Female Sexual Distress Scale, and the Major Depression Inventory.

RESULTS: Predialysis patients reported lower Female Sexual Function Index scores compared to the controls (14.2 ± 2.1 vs. 20.1 ± 1.7, respectively, p = 0.048), more frequent sexual distress (44 vs. 22 %, respectively, p = 0.044), and more frequent sexual dysfunction (41 vs. 17 %, respectively, p = 0.041). There was no difference between the patients' and the controls' depression scores (12.2 ± 2.2 vs. 8.6 ± 1.1, respectively, p = 0.180).

CONCLUSION: Sexual dysfunction was found to be more than two times as frequent in Danish female predialysis patients with CKD stage 4-5 compared to age- and gender-matched healthy controls, and this result emphasizes the need for attention towards sexual function in the treatment for CKD.
