Abstract

OBJECTIVE:

To determine whether subjective or objective seasonal changes occur in patients with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH).

MATERIAL AND METHODS:

A total of 31 patients with LUTS were observed for >5 years. Their International Prostate Symptom Score (IPSS), quality of life (QOL) score, maximum flow rate (Qmax), voided volume (VV) a nd post-void residual (PVR) we re measured every month.

RESULTS:

Total IPSS, QOL, VV or PVR did not show any seasonal changes between the three seasons: summer (hot season: June to September); winter (cold season: December to March); and spring and fall (comfortable season: April, May, October and November). Furthermore, when the IPSS was examined by dividing it into storage symptoms (frequency, urgency and nocturia) and voiding symptoms (incomplete emptying, intermittency, weak stream and straining), no significant seasonal changes were detected. Only Qmax showed a significant seasonal change, being higher in both the cold season (median 10.4 ml/s) and the comfortable season (median 10.1 ml/s) than in the hot season (median 9.4 ml/s).

CONCLUSIONS:

It has generally been thought that LUTS worsen in winter. Our results indicate that the IPSS and the QOL score remain nearly constant if they are determined regularly over an extended period of time. Qmax may however be influenced by seasonal changes in temperature.
