To re-survey (after 1 year) men identified in 1999 as having perineal and/or ejaculatory pain/discomfort severe enough to suggest a clinical diagnosis of chronic prostatitis (using the National Institutes of Health-Chronic Prostatitis Symptom Index, NIH-CPSI), and to compare them with an age-matched population of men who had no prostatitis-like symptoms in the initial survey, to determine the effect of time on specific symptoms associated with the diagnosis of chronic prostatitis. ⋯ About a third of men reporting prostatitis-like symptoms in the general population had resolution of their symptoms (usually those with a shorter duration and less severe symptoms) 1 year later. The severity of symptoms of men with persistent chronic prostatitis remained relatively unchanged over the year.

To examine, in young pigs, changes in baseline pelvic pressure and diuresis in the contralateral kidney during conditions of increasing pelvic pressure and perfusion with isotonic saline in the ipsilateral renal pelvis; the role of a reno-renal nervous mechanism was examined by denervating the kidneys, and the effect of bladder filling on these variables assessed. ⋯ These results indicate that a reno-renal reflex mechanism has no apparent role in young pigs during pressure-perfusion measurements with an empty or full bladder.

To determine the long-term efficacy and complications of sacral nerve stimulation as an alternative therapy for functional unobstructive urinary retention, often considered to be psychogenic and effectively treated by clean intermittent catheterization, but for which pelvic floor dysfunction has been recognized as a possible cause. ⋯ Sacral nerve stimulation is an effective and durable new approach to functional urinary retention, with few associated complications. Test stimulation provides a valuable tool for selecting patients.
