Randomized trial - oxybutynin for treatment of persistent plantar hyperhidrosis in women after sympathectomy.

Objective: Hyperhidrosis is a common disease, and thoracoscopic sympathectomy improves its symptoms in up to 95% of cases. Unfortunately, after surgery, plantar hyperhidrosis may remain in 50% of patients, and compensatory sweating may be observed in 70%. This clinical scenario remains a challenge.
