Tumour\u2010suspicious findings leading to surgical intervention were detected in 17 (2.9%) by UC alone and in three (0.5%) by BWC but unsuspicious UC, respectively. Overall, relevant histological findings after transurethral bladder surgery (TUBS) were detected in eight (1.4%, 95% confidence interval [CI] 0.6\u20132.7%) patients: keratinising squamous metaplasia (two) and non\u2010muscle\u2010invasive urothelial carcinoma (six), all were initially identified by UC. Three patients refused surgery, two of whom had positive BWC without suspicious lesion in UC. Sensitivity and specificity of BWC referenced to UC alone were 0% (95% CI 0.0\u201336.9%) and 99.7% (95% CI 98.7\u201399.9%), respectively. Adding BWC to UC increased costs by 22.8% without improving tumour detection. The main study limitation was the lack of true positives in BWC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Bladder washing cytology in addition to UC is not justified in the initial evaluation of patients with neuro\u2010urological disorders as decision making regarding TUBS is based on UC findings.
