Applying well-defined inclusion and exclusion criteria, we have selected all the patients who have reported that falling during the night, on the way to the toilet (for micturition), was the event leading to the hip fracture. A comprehensive medical history and the International Prostate Symptom Score (IPSS) Questionnaire were gathered from all the patients and the obtained data were analyzed.Results: From a total of 363 patients with hip fractures, 68 cases were attributable to night-time voiding. The detailed analysis of the 68 patients has shown that all of them had significant nocturia (2.72 episodes of voiding per night, in average), but only 11 of them were already diagnosed with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). Moreover, only four of the eleven patients diagnosed with BPH were taking specific therapy at the moment of their falling leading to hip fracture. Subsequent analysis has shown that a group of 45 patients with no previously known co-morbidities, had similar IPSS score results with the total group of 68 patients.Conclusions: Night-time voiding and LUTS are underdiagnosed in the general male population, as they represent significant risk factors for hip fractures due to falling during the night. The low level of BPH/LUTS therapy adherence adds a supplementary risk for falling during the night.Keywords: hip fracture, night-time voiding, nocturia, low urinary tract symptoms, risk factors
