Résumé
Benign prostatic hyperplasia [BPH] is a common age-related urological disorder. Patients can subjectively descript their micturition habits by using the international prostate symptom score [IPSS] but whether or not patients answer correlate with their uroflowmetic findings has not been validated objectively. The aim of this study was to evaluate the correlation of patient answers with findings on uroflowmetry studies. eighty six patients with lower urinary tract symptoms [LUTS] were evaluated by IPSS and uroflowmetry. IPSS was divided into voiding and storage symptoms. Waiting time, voided volume, maximum and average flow rates were recorded. The relationship between these parameters was quantified by SPSS software Pearson correlation coefficient. Patients were aged 46 - 79 years old. Age did not correlate by Qmax, Qave, IPSS and voided volume. Voided volumes were 109-647ml [mean=259.5 ml]. Qmax was <15ml/s in about 63% of patients [54 patients] independently of age. Qmax was correlated negatively with total IPSS score and voiding symptoms but did not correlate with storage symptoms. Qave correlated only with voiding symptoms[p=0.04] but not with total IPSS and storage symptoms. Waiting time did not correlate with total IPSS, voiding and storage symptoms. There is a close correlation between IPSS and uroflowmetry results.uroflowmetry is a more suitable for LUTS paitents who have improper understanding the IPSS questions due to cultural or language problems
