text_2: "Urinary incontinence is a significant health problem that is frequently unrecognized or untreated in many older adults. While the prevalence of incontinence increases with age this does not mean it is part of the normal aging process and many older adults may be unaware that it is a treatable condition. There is good quality evidence that behavior and lifestyle modification, some medications, and/or surgery can improve or resolve urinary incontinence. In 2001, the FDA approved the InterStim sacral nerve stimulation system for the treatment of urge incontinence. Current evidence on the safety and efficacy of sacral nerve stimulation for urge incontinence appears adequate to support the use of this procedure, however patient selection is important. The diagnosis should be defined as clearly as possible and the procedure limited to patients who have not responded to conservative treatments. The story refers to a review that found 4 randomized, controlled trials of the device. The story could have provided more detail about the strength of these studies and pointed out the limitations on the current evidence, such as the small sample sizes, limited follow up time and whether these studies were funded by the device manufacturer. However, the story fell short in quantifying the benefits of treatment. The story provides some quantification of benefits of the device but leaves many questions unanswered. The story states that 80% of the patients experienced at least a 50% improvement in symptoms with the device. Compared to how many with conventional treatment? What does an ""improvement"" mean? In what symptoms? How was improvement measured?"
