Polish versions of the Qualiveen and the SF-Qualiveen: Translation and validation of urinary disorder-specific instruments in patients with multiple sclerosis.

The Polish Qualiveen and SF-Qualiveen are reliable, valid, and consistent measures of urinary disorder-specific quality of life in patients with MS. After years of no appropriate Polish instrument being available for healthcare professionals to evaluate patients with MS, we provide these versions and recommend their use in research and clinical practice in Poland.
