Resumen
ENCARNACION-CADENILLAS, Edwin et al. Clinical and urodynamic features of the hypoactive detrusor in women. Rev Med Hered [online]. 2023, vol.34, n.4, pp.193-201. Epub 20-Dic-2023. ISSN 1018-130X. http://dx.doi.org/10.20453/rmh.v34i4.5142.
Objective
: To describe the clinical and urodynamic features of the hypoactive detrusor (DU) in women.
Methods
: Cross sectional comparative study between two groups of women with lower tract urinary symptoms. Group 1 were patients with Pdet Qmax 30 or with the bladder emptying efficiency (BVE) criteria, and Group 2 were patients without DU. Central tendency measures and proportions were used to report results and parametric tests were performed to compare groups.
Results
: 155 patients were included, 44 with DU (Group 1) and 111 without DU (Group 2); mean age was 60,8 ± 16,3 and 55,7 ± 13,4 respectively (p=0,0468). Nocturia (p=0,0061) and micturition effort (p=0,000) were the only variables identified in the bivariate analysis who achieved statistical significance. Mean Watts factor (WF) was 3,2 ± 1,0 y 6,0 ± 2,2 in Group 1 and 2, respectively (p=0,000), while mean projected isovolumetric pressure 1 (PIP1) was 28,0 ± 7,5 and 45,9 ± 11,2, respectively (p=0,000). The multivariate analysis identified age above 60 years, nocturia and micturition effort associated with DU.
Conclusion
: Urodynamic parameters such as PIP1, BCI, BE and WF showed significant difference in the bivariate analysis, WF<5 and BCI <80 are best predictors of DU.
