Introduction Isaacs's syndrome (IS), is a rare neurological disorder, characterized by sustained muscular activity, fasciculations, cramps, myokymia, excessive sweating, and occasional elevation of creatine phosphokinase (CPK) enzyme. Aim To report our experience in patients with IS and urinary manifestations, describing clinical findings, test's results, and response to treatment. Methods An observational, retrospective analysis of patients with IS and urinary manifestations treated at German Hospital of Buenos Aires between 2001 and 2011 was done. Diagnosis was performed with clinical examination and electromyography (EMG) of external sphincter of the anus and/or urethra. Demographic, clinical, and treatment variables were analyzed. International Prognostic Scoring System (IPSS) at diagnosis and follow up was made. Results Eleven IS patients were recruited, of whom 8 (72.72%) were females with a mean age 47.87 years (DS ± 13.95) and presented associated lower tract urinary symptoms (LUTS). Six of them (75%) had voiding and 2 (25%) filling symptoms. Urodynamic and electromyographic findings reproduced symptomatology in all patients. Patients with voiding symptomatology were treated with combination of alpha‐blockers with benzodiazepines; membrane stabilizings agents; antiepileptics; neurotropic; corticoids; posterior tibial nerve stimulation and botulinum toxin, achieving improvement in 4/6. The two patients with storage symptoms were treated in first instance with anticholinergic drugs, one of which did not respond completely was added oral pentosansulfate and electrical stimulation, reversing the symptomatology. Four patients had associated pathologies: Hashimoto's thyroiditis; Sjögren's syndrome; dysautonomia, and myasthenia gravis. Conclusions In our experience, IS urinary manifestations are common and usually has a good evolution with adequate treatment for each patient.
