Effects of TORS-OSA surgery on lower urinary tract symptoms, overactive bladder symptoms, and nocturia in male patients with obstructive sleep apnea/hypopnea syndrome


Advanced Center for Specialty Care, Advocate Illinois Masonic Medical Center


Objective: To determine the presence of lower urinary tract symptoms (LUTS), and overactive bladder (OAB) symptoms in men with obstructive sleep apnea/hypopnea syndrome (OSA) and the effects of transoral robotic surgery (TORS) for the treatment of OSA on these conditions.

Materials and methods: One hundred twenty-three patients with a diagnosis of OSA were prospectively enrolled. The evaluations of LUTS and OAB symptoms were based on self-administered questionnaires containing international prostate symptom score (IPSS) and OAB symptom score (OABSS), respectively. Men with an OABSS urgency score of ≥2 and sum score of ≥3 were considered to have OAB. The therapeutic outcomes were assessed at baseline, and 12 weeks after TORS-OSA Surgery.

Results: There were significant differences in IPSS, and OABSS according to OSA severity. After TORS-OSA surgery, significant improvements on OSA severity, daytime quality of life (QoL) and nighttime sleep quality were observed. TORS-OSA surgery was also associated with a statistically significant improvement of LUTS, LUTS QoL score, and OAB symptoms (IPSS 22.1% decrease; IPSS QoL score 21.1% decrease; OABSS17.4% decrease) at post-operative 3 months' follow-up. The presence of OAB, and severe nocturia was significantly reduced from 22.8% to 11.4% (p=0.001), 5.7% to 0.8% (p=0.031) after TORS-OSA surgery. There were no patients who had acute airway compromise or massive bleeding peri- or post-operatively.

Conclusion: TORS upper airway surgery could improve LUTS and OAB symptoms on male patients with OSA in addition to improvement of major parameters of sleep study and sleep-related QoL.
