AIMS: There is limited data on bladder compliance associated with lower urinary tract dysfunction. The aim of this study was to investigate the decrease in bladder compliance, and the clinical relationship between patterns of increased pressure with neurological disease. MATERIALS AND METHODS: A retrospective analysis was performed in 5,027 patients with voiding dysfunction between June 2002 and April 2008. The patients with poor compliance (PC) were categorized according to the detrusor pattern of increased pressure: group A (gradual increase), group B (terminal increase), and group C (abrupt increase and plateau). RESULTS: Patients with PC were found in 170 (3.4%) cases (76 males and 94 females) with 46.5% in group A 44.7%, group B, and 8.8% group C. Bladder trabeculation was more prevalent in patients with PC than among those with normal compliance. Group A had the highest correlation with the incidence of spinal cord injury compared to the other groups. Group B had a higher correlation with a history of pelvic irradiation, radical prostatectomy, and tethered cord syndrome compared to the others. Vesicoureteral reflux was more frequently detected in group A and group C. Group C was positively correlated with the presence of detrusor overactivity and nocturnal enuresis. CONCLUSIONS: Poor compliance was correlated with the presence of neurological conditions. The gradual increase of detrusor pressure was associated with the development of spinal cord injury, and the terminal increase had an association with a history of treatment to the pelvic cavity.
