OBJECTIVE: The degree of severity of the undesirable mictional problems caused by BPH is assessed according to the scores obtained in the acknowledged and validated IPSS questionnaire. METHOD: In accordance with the WHO recommendations, the IPSS was proposed to patients (n=189) in the form of a self-questionnaire with the aim of analyzing the obstruction and irritation scores for the patients suffering from a recently diagnosed BPH and treated with Serenoa Repens RESULTS: The IPSS obstruction score was respectively 6.7 (3.8) and 5.9 (3.5) upon patient inclusion and after six months. This noted difference is statistically significant (p<0.0001). The IPSS irritation score was respectively 5.5 (2.6) and 4.5 (2.3) upon patient inclusion and after six months. This difference is here statistically significant with p<0.0001. CONCLUSION: Treatment by first intention with Serenoa Repens thus showed a significant improvement as demonstrated by both the obstruction and irritation scores.
