IPSS storage score as a predictive tool of quality of life improvement to apply in therapeutic interventions.

OBJECTIVES: The questionnaire International Prostate Symptom Score (IPSS) is well known and used in clinical practice as diagnostic tool and allows for obtaining a total score regarding the severity of the urinary symptoms. The objective of this analysis is to determine if the IPSS storage score (sum of the punctuation of the questions 2, 4 and 7) could be a predictive variable of the impact on quality of life. MATERIALS AND METHODS: Post-hoc analysis of an epidemiological, multicenter, cross-sectional study inmale patients, >/=18 years old with >/=6 micturitions and>/=1 urgency and/or >/=2 nocturia and/or >/=1 daily incontinence episodes recruited by 291 urologists across Spain. Socio demographic variables, symptoms reported by patients (IPSS) and clinical variables were collected. The impact of voiding symptoms (IPSS-V) and storage symptoms (IPSS-S) on the quality of life, measured using the Overactive Bladder questionnaire Short Form(OABq-SF HRQoL), was evaluated using multivariate regression models (linear and logistic). RESULTS: 958 patients, whose mean score (standard deviation) of the OABq-SF HRQoL was 57.9 (18.3),were included in the study. 55.6% received drug treatment for urinary symptoms. 616 patients (64.4%) reported a puntuation >3 in the item 8 of the IPSS. The adjusted analysis showed a significant reduction in the qualityof life of -1.1 (p<0.001) and -3.3 (p<0.001) points associated with the worsening of the symptoms of voiding and storage respectively. This worsening was also associated with a minor risk of satisfaction (OR=1.14;p<0.001 and 1.36; p<0.001) for the voiding and storage symptoms respectively. CONCLUSION: In patients with mixed LUTS both components show a negative effect on the quality of life, with a greater impact of the storage symptoms.
