Post Treatment Change of Nocturia in Patients with Benign Prostatic Hyperplasia

ABSTRACT

PURPOSE: It seems that nocturia is not improved even after various forms of treatment in benign prostatic hyperplasia(BPH) patients. We studied the relationship of nocturia with other components of the International Prostate Symptom Score(IPSS) in BPH patients and also evaluated the changes of nocturia score following medical or surgical treatments to determine whether the nocturia score behaves differently. MATERIALS AND METHODS: Between March 2002 and March 2004, a total of 198 men with BPH were enrolled in this study. Baseline symptom scores and the change after treatment were analyzed particularly focused on nocturia score. RESULTS: On baseline score analysis, the nocturia score correlated with frequency and urgency scores(p=0.01). Total IPSS score was changed from 21.8+/-6.5 to 10.1+/-6.7 after treatment(p<0.001). The changes of nocturia score were 2.4+/-1.2 to 1.8+/-1.1 in the younger group and 3.1+/-1.3 to 2.2+/-1.2 in the older group, 2.9+/-1.3 to 2.1+/-1.1 in the surgical treatment group and 2.3+/-1.2 to 1.7+/-1.1 in the medical treatment group. The improvement of nocturia score was minimal after treatment. CONCLUSION: It seems that nocturia score behaves differently in the symptom complex of BPH. These facts should be considered when we consult patients with BPH complaining of nocturia.
