Aims The primary aim is to explore the adherence predicting factors in clean intermittent self‐catheterization (CISC) in patients aged over 65 years. The secondary aim is to assess whether in this population, the non‐adherence risk is greater, compared with patients under 65. Methods All patients older than 65 that successfully learned CISC between January 2011 and January 2016 were included. A control population younger than 65 matched with sex, body mass index, and pathology was selected. Results One hundered and thirteen (66.9%) out of the 169 patients older than 65 included were adherent at 1 month, and 80 (47.3%) at 6‐12 months. Obesity (P = 0.027), a low PP test (Pencil and Paper test) score (P = 0.037), significant urinary stress incontinence (SUI) (P = 0.048), and prescription of CISC less than three per day (P = 0.03) were the risk factors predicting stopping CISC at 1 month, but none was associated with non‐adherence at 6‐12 months. Compared with the younger group, age was a risk factor for poor adherence at 1 month. Conclusion Obesity, low PP test score, and important SUI are factors of poor adherence to CISC at 1 month in older adults. Necessity of more than three CISC per day is in favor of treatment continuation, possibly due to absence of spontaneous voiding in these patients. Long‐term adherence to CISC in older adults in this study remains close to adherence to other treatments prescribed in urinary disorders, and thus shows that CISC could be an easily purposed therapeutic option in this population, either on a long‐term or transitory basis.

Objectives: To determine whether diffusion-weighted magnetic resonance imaging (DWMRI), a noninvasive procedure, can contribute to the diagnosis of bladder pain syndrome/interstitial cystitis (BPS/IC). Methods: The pelvic DWMRI of patients with chronic pelvic pain syndrome was selected between January 2012 and June 2017. A radiologist analyzed the bladder wall signal; he was blinded to the patients’ clinical data. According to the 2008 European Society for the Study of Bladder Pain Syndrome/Interstitial Cystitis criteria, 2 groups of patients were determined: BPS/IC and no BPS/IC. The association between BPS/IC and the wall signal intensity was compared. Results: In the 106 patients included, 82 had criteria for BPS/IC and 24 did not. A significant difference in the distribution of the signal was found between the 2 groups (p = 0.01). High signal intensity of the bladder wall was related to the presence of a BPS/IC with a sensitivity of 28% and a specificity of 88%. No signal intensity of the bladder wall was related to the absence of a BPS/IC with a sensitivity of 96% and a specificity of 29%. Conclusions: In ­DWMRI, high bladder wall signal intensity helps to affirm a BPS/IC, whereas the absence of signal helps to exclude the diagnosis. Further studies are needed to confirm these preliminary results.
