Abstract

PURPOSE: We compared the recovery periods in zoster-associated voiding dysfunction according to the treatment modality to establish the best treatment policy.
MATERIALS AND METHODS
From January 2004 to August 2006, medical records of 250 patients admitted for zoster infection were reviewed. Of 250 patients, patients complaining of lower urinary tract symptoms(LUTS) were selected. The clinical and urodynamic features, and treatment outcomes were analyzed.
RESULTS
Thirty eight(15.2%) of 250 patients had zoster-associated LUTS. Urinary retention was the most common symptom. Urodynamically, detrusor underactivity was the most common finding(71.8%). Twenty were followed, of which 5 received oral medication, 10 received clean intermittent catheterization(CIC), 4 received indwelling catheterization(IC) and remained 1 was observed without treatment. All patients regained normal voiding function. Mean recovery period was 12 days. According to the treatment modality, mean recovery period was 21 days in medication group, 10 days in CIC group, and 6 days in IC group. The mean recovery period was significantly shorter in CIC or IC group than medication group(p=0.013, 0.005).
CONCLUSION
Zoster-associated voiding dysfunction is a reversible condition. Thus, patients with mild symptoms can be observed. However, if symptoms are severe or retention develops, catheterization is recommended rather than medication alone.
