Résumé

INTRODUCTION: The Canadian Urological Association (CUA) neurogenic bladder guideline surveillance strategy for neurogenic lower urinary tract dysfunction (NLUTD) has not been formally evaluated. Our objective was to evaluate the validity of the risk stratification suggested in these guidelines.

METHODS: This was a prospective, observational cohort study of adult NLUTD patients with spinal cord injury, multiple sclerosis, or spina bifida who required urodynamics. Patients with a requirement for immediate bladder surgery (not suitable for surveillance) were excluded. Patients completed standardized medical history/questionnaires, baseline urodynamics, renal imaging, and creatinine tests. The primary outcome was the need for different types of urological management between the high-risk and moderate-risk groups.

RESULTS: We enrolled 68 patients; most commonly, these were spinal cord injury patients, and most people were using intermittent catheters. At baseline, 62% (40/68) were classified as high-risk. In this group, there was a numerically greater proportion who received a recommendation for a new urological medication (48% vs. 25%, p=0.06) or a change to their bladder management (45% vs. 36%, p=0.44). A total of 26 high-risk and 23 medium-risk NLUTD patients had a one- year followup visit. A larger proportion of the high-risk patients had a recommendation for a new bladder medication (15.4% vs. 8.7% p=0.47), intravesical onabotulinum toxin (34.6% vs. 13% p=0.08), or an alternate method of bladder management (15.4% vs. 4.3%, p=0.2). Mean creatinine change was slightly greater in the high-risk group (+6.1 vs. +0.4 umol/L, p=0.05). Approximately 1/3 of both high-risk and moderate-risk patients didn’t accept the recommended interventions.

CONCLUSIONS: A higher proportion of high-risk NLUTD patients had urology-relevant interventions recommended, both at baseline and at their one-year followup visit. This supports the general concept of risk stratification and the variables used to define high risk in the CUA’s neurogenic bladder guideline.
