Videourodynamic analysis of the urethral sphincter overactivity and the poor relaxing pelvic floor muscles in women with voiding dysfunction.

Abstract:

AIMS:Voiding dysfunction due to dysfunctional voiding (DV) and poor relaxation of the external sphincter (PRES) are commonly found among adult women with lower urinary tract symptoms (LUTS) during videourodynamic study (VUDS). This study analyzed the VUDS characteristics of DV and PRES in female voiding dysfunction. METHODS:This retrospective study involved 1914 women aged >18 years with refractory LUTS. The medical records and the VUDS parameters were reviewed. Patients diagnosed with DV and PRES participated in the study. The VUDS characteristics and urethral sphincter activities were compared with those of urodynamically normal women. RESULTS:Of the 1914 women, 325 (17.0%) and 336 (17.6%) were diagnosed with DV and PRES, respectively. Detrusor overactivity (DO) occurred in 60% of the women with DV and in 5.7% of the women with PRES. Patients with DV had significantly increased bladder sensation, lower cystometric bladder capacity (CBC), lower bladder compliance, higher voiding detrusor pressure, smaller voided volume (VV), larger post-void residual volume (PVR), lower voiding efficiency (VE), and higher bladder outlet obstruction index (BOOI) than the women with PRES and the control individuals. Patients with PRES had significantly increased bladder sensation, lower CBC, lower maximum flow rate, smaller VV, larger PVR, and lower VE than the control individuals. CONCLUSIONS:DV and PRES were highly prevalent among the adult women with voiding dysfunction. Patients with DV had VUDS characteristics of BOO and urodynamic DO. The clinical symptoms of PRES were similar to those of DV, but the patients had low detrusor contractility and low DO rates.
