摘要
Purpose. The lazy bladder syndrome (LBS) is characterized by an infrequent voiding, a large bladder capacity without neurological or urological disorders. In spite of being relatively common, there is little literature about it. The aim of our study was to compare the clinical features and urodynamic findings in asymptomatic or symptomatic patients with lazy bladder syndrome. Patients and methods. We reviewed the charts of 126 adult patients diagnosed with lazy bladder syndrome. Clinical and radiological features, urodynamic findings and therapeutic management were evaluated. With these data, we divided patients into 2 groups: asymptomatic and symptomatic patients. After, we performed a comparative analysis of the data. Results. The incident of LBS was significantly higher in women (81%). Twenty-one patients were asymptomatic (17%), 105 patients were symptomatic (83%). The patients with symptomatic LBS were significantly older (54.3 years +/- 14.7). Voiding dys53%) and urinary retention (27%) were the most common symptoms in symptomatic group. In the uroflowmetry test, maximum and mean uroflow were significantly higher in asymptomatic group (P=0.0074). Reduced bladder sensation revealed no difference in the 2 groups, but in the symptomatic group, detrusor has also a poor contractility (P=0.0001). Nineteen patients (18%) had uro-nephrological complications. Conclusion. LBS is certainly underestimated. Voiding dysfunction, urinary retention in infrequent voiders or uro-nephrological complication (urinary tract infection with fever, ureteral reflux...) should recall LBS diagnosis. The hypothesis of bladder structural failure or autonomic nervous system dysfunction may be discussed (suggested). Level of evidence. 5.
