Unsuccessful linguistic validation of the Symptom Questionnaire for assessing quality of life in Polish patients with pelvic vein disorders.

Pelvic venous disorder (PeVD) is a prevalent chronic condition characterized by the presence of varicose veins in the pelvis, leading to the development of chronic pelvic pain. Despite the growing interest in assessing quality of life in PeVD, well-designed and validated disease-specific questionnaires are missing. The objective of this study was a linguistic and clinical validation of the Symptom Questionnaire (SQ) in a cohort of Polish females with pelvic vein incompetence.
