Aims and methods. LUTS suggestive of BPH.

OBJECTIVE: Few epidemiological studies are available on Italian patients with lower urinary tract symptoms and their QoL. QUIBUS (QUality of life Investigated in BPH patients with Urinary Symptoms) is an observational longitudinal study aimed at evaluating symptoms and QoL in a large sample of Italian patients and investigating their correlation with demographic, social and clinical characteristics of BPH. PATIENTS AND METHODS: Patients with lower urinary tract symptoms and prostate enlargement suggestive of BPH (both old and new diagnosis) were enrolled between November 1998 and May 1999 in 31 Italian centers of urology. This longitudinal investigation consists of an enrollment visit, in which demographic, social and clinical aspects are recorded as baseline data, and a follow-up visit after 1 year of treatment freely assigned by the investigators. Symptoms and QoL are assessed by means of IPSS, ICS-BPH (at both visits) and SF-36 (only at the follow-up visit) questionnaires. RESULTS: 1,033 patients were enrolled. The follow-up visit is still under evaluation. In this series of papers the baseline results are presented and discussed in terms of (i) medical management, (ii) life-style, (iii) symptoms, bothersomeness and QoL, (iv) sexual function of a large and representative sample of Italian patients and (v) uroflowmetry.
