[Evolution of the USP and IPSS score after continuous positive airway pressure sleep apnea therapy at night].

To assess the impact of nocturnal continuous positive airway pressure (CPAP) treatment of obstructive sleep apnea (OSA) on lower urinary tract (LUTS) symptoms. A prospective, monocentric study was conducted between June 2018 and August 2019. Patients with moderate to severe OSA with an indication for treatment with nocturnal CPAP in combination with SBAU were included. SBAUs and their impact were evaluated by completing two self-administered questionnaires (Urinary Symptom Profile (USP) and International Prostate Score Symptom (IPSS)) filled out during the night-time ventilatory polygraph or diagnostic polysomnography for OSA and after 4 months of CPAP treatment. In 79 patients, after four months of CPAP treatment, USP scores for stress urinary incontinence and overactive bladder were significantly improved, respectively 0.65±1.38 vs 1.13±2.10 ; p<0.0001 and 3.24±2.58 vs 5.43±3.66 ; p<0.0001, IPSS and IPSS-Qdv were significantly improved, respectively 5.20±3.78 vs. 7.44±5.05 ; p<0.0001 and 1.93±1.26 vs. 2.27±1.56 ; p=0.002 as well as IPSS score items on pollakiuria, urgency and nocturia. Treatment with CPAP significantly improved SBAU in four months. Testing urology patients for symptoms of OSA in urology patients seeking SBAU would allow referral of patients suspected of OSA to a specialist for diagnosis and management if necessary.
