Nocturnal polyuria in community‐dwelling women

In this section there are papers describing studies into nocturnal polyuria, the overactive bladder in Asian men and the use of extracorporeal magnetic stimulation for female urinary incontinence. There are also papers which evaluate the cost implications of microwave thermotherapy, the accumulation of proteoglycans in prostatic hyperplasia, and the presentation and management of urethral calculi. The last two papers in this section have nothing directly to do with the lower urinary tract. Indeed, they do not fit into any of the groups of papers in the journal but I felt that they were of general interest to the readership of the BJU International, and so felt they could really be put into any section! OBJECTIVE To determine the age prevalence of nocturnal polyuria among older women in the community, and to investigate the relationship between nocturnal polyuria and nocturia. PATIENTS AND METHODS In all, 1183 women aged ≥ 50 years, who were registered with a family doctor practice and who had taken part in a prevalence study, were sent brief questionnaires and a frequency/volume chart (FVC) to complete. RESULTS There were 227 FVCs with adequate data and 264 completed questionnaires available for analysis. The prevalence of nocturnal polyuria increased disproportionately with age. There was no clear relationship between nocturia or nocturnal polyuria and daytime frequency, nor was there a clear relationship between diuretic use and nocturnal polyuria. CONCLUSION Nocturnal polyuria is common among women in the community and not obviously related to daytime frequency. Night‐time symptoms are common in women as well as men, and are troublesome to them.
