ABSTRACT

Objective: Compare the different definitions for bladder outlet obstruction (BOO) in women with dysfunctional voiding (DV) and find which one is most specific and sensitive to achieve a more accurate diagnosis.
Materials and methods: a cross-sectional study of urodynamic investigation studies fr om women diagnosed with DV in a period from 2017-2020 were classified with obstruction or not, based on 6 urodynamic definitions. The control group were women who had been categorized with obstruction in at least 3 definitions of BOO. Likelihood positive ratio, sensitivity and specificity were calculated. Statistical analysis was carried out by IBM SPSS Statistics for Windows, Version 23.0 (IBM Corp., Armonk, N.Y., USA). A p <0.5 was considered statistically significant.
Results: A total of 146 urodynamic studies were analyzed, Solomon-Greenwell nomogram has shown to be the more specific and sensitive, obtaining the highest likelihood positive ratio >100. The comparison between our the control group and every definition of BOO has shown statistically significant difference.
Conclusions: The diagnosis of BOO requires expertise and individualization, it is made through physical examination and complete urodynamic study, Solomon- Greenwell has shown to be specific and sensitive for diagnosis in the group of study.
