Abstract:
Objective To analyze videourodynamic characteristics of female bladder outlet obstruction (BOO). Methods Retrospective analysis of videourodynamic characteristics were performed in 42 women with BOO. On the basis of the videourodynamic findings, women with BOO were categorized into five groups: bladder neck obstruction, middle urethra (urethral sphincter) obstruction, distal urethra obstruction, external orifice of urethra obstruction, high-grade pelvic organ prolapse. Data of five groups were compared in Qmax, maximum cystometric capacity, Pdet at Qmax, residual urine, detrusor instability and hydronephrosis. Data of all patients were analyzed by SPSS13 statistical software, measurement data by t-test and enumeration data by x2-test. Results Five groups had not significant deviation in the maximum cystometric capacity. however patients with bladder neck obstruction had significant deviation with others in Pdet at Qmax (78. 0 ± 23. 6)cm H2O, residual urine (120. 6±115.2)ml, Qmax (7.0±2.3)ml/s (P<0.05). There was significant deviation between middle urethra (urethral sphincter) obstruction(76.9%)and others in detrusor instability(P<0. 05). In all patients with hydronephrosis, bladder neck obstruction(57. 1 %) had significant deviation with others (P<0. 05). Conclusions Videourodynamic tests could assess lower urinary tract function, and may guide clinic management. The bladder neck obstruction was most serious and harmful to upper urinary tract.
