Abstract

Peyronies disease (PD) is characterized by fibrosis of the tunica albuginea of the penis with plaque formation within its thickness. It manifests as penile pain, penile curvature, and erectile dysfunction, with a psychological impact on affected men.
To translate the questionnaire into Russian and to adapt and validate the Russian-language version of the PDQ (Peyronies Disease Questionnaire) for use in clinical practice and research.
The PDQ was translated in this study. The translation process was carried out in accordance with recommendations for validation and adaptation. The study included 36 patients with Peyronies disease who presented to the Urology Clinic of Sechenov University from February 2025 to May 2025. They completed the PDQ at the initial visit and again 7 days later at a follow-up visit.
Internal consistency and reliability were assessed using Cronbachs alpha coefficient, which demonstrated excellent consistency at both visits. For all questions, the results of the two visits showed high correlation, greater than 0.8, indicating stable reproducibility of the results.
Owing to the translation and validation of the PDQ into Russian, PDQ-RU (Peyronies Disease Questionnaire-Russia), clinicians now have a valuable and convenient tool for assessing clinical manifestations and quality of life in patients with Peyronies disease.
factor analysis to assess structural validity was not feasible due to the small sample size (KMO < 0.7); absence of an external validation criterion; and the single-center design of the study.
Translation and validation of the PDQ for Russian-speaking patients provides a useful, convenient, and reliable tool for clinical assessment of quality of life as well as treatment outcomes in patients with PD.
