Noguchi N, et al. - An elucidation was carried out of the natural history of post-void residual urine volume (PVR) in community-dwelling older men. The inference drawn was that the conservative management could be suitable for most older men with incidentally found elevated PVR of up to 400 mL.

Methods

• This study was a Concord Health and Ageing in Men Project.
• It encompassed a representative sample of community-dwelling men aged 70 and older in a defined geographic area of Sydney, Australia.
• PVR were measured at baseline and 2-year and 5-year follow-up.
• The estimations were valid when the voided volumes were 150 mL and over.
• This study consisted of three-hundred twenty-nine men without conditions possibly altering PVR (neurological disorders, prostate cancer, and a history of urological treatment).

Results

• It was noted that the baseline PVR were 0-49 mL in 183 men, 50-99 mL in 59 men, 100-199 mL in 72 men, 200-399 mL in 11 men, and 400 mL and over in 4 men.
• Thirteen out of 314 (4%) men with a baseline PVR of 0-199 mL and 2 out of 11 (18%) men with a baseline PVR of 200-399 mL, underwent surgery for benign prostate enlargement (BPE) or indwelling catheterization over 5 years compared to three out of four men (75%) with a PVR of 400 mL and over.
• In 101 men with a baseline PVR of less than 400 mL not receiving the urological therapy during follow-up, with valid PVR data for both 2-year and 5-year follow-up, PVR did not exceed beyond 400 mL, at either follow-up time point.
