Polysomnographic and urodynamic changes in a case of obstructive sleep apnea syndrome with enuresis.

Abstract

A 53-year-old female patient with obstructive sleep apnea syndrome was reported. She had complained of enuresis as well as a 15-year history of snoring, but she had no complaint of sleep and awake disturbance. Polysomnographic study showed repeated obstructive apnea and hypopnea with an apnea/hypopnea index of 52.6, and severe oxygen desaturation during sleep. On cystometography during sleep, the changing amplitude of the spike wave corresponds to the changes of respiratory efforts against a closed upper airway. The patient was treated successfully with imipramine and acetazolamide for the obstructive sleep apnea and enuresis. Apnea/hypopnea index, nocturnal oxygen desaturation, and sleep architecture were improved, and enuresis completely disappeared. Cystometrography during sleep showed that the average amplitude of the spike wave tended to be low. Percentage urinary volume during sleep compared with 24 h volume was significantly reduced. We considered that the enuresis was mainly related to increased intra-abdominal pressure produced by respiratory efforts and enhanced nocturnal urine production.
