title: Risk factors affecting cure after mid-urethral tape procedure for female urodynamic stress incontinence: comparison of retropubic and transobturator routes.
abstract: OBJECTIVE
  To identify the risk factors affecting cure after the tension-free vaginal tape procedure (TVT) or transobturator tape procedure (TOT).
  
  
  METHODS
  A total of 121 women with urodynamically proved stress incontinence underwent TVT (n = 61) or TOT (n = 60). We analyzed all data with univariate and multivariate logistic regression analyses.
  
  
  RESULTS
  Univariate analysis revealed that a larger postvoid residual urine volume, greater pad weight test, and lower maximal flow rate were associated with a greater risk of failure to be cured after TVT. A lower maximal urethral closure pressure (MUCP) was associated with a greater risk of failure after the TOT procedure. With additional analysis, we found that a MUCP of <or=40 cm H(2)O (odds ratio [OR] 9.21, P = .004) was associated with a significantly greater risk of failure to be cured after the TOT procedure but not a MUCP of <o=50 cm H(2)O (OR 2.24, P = .21). Multivariate analysis revealed that preoperative detrusor overactivity was an independent risk factor affecting cure after TVT (OR 113.1, 95% confidence interval 1.84-6592.77, P = .02) or TOT (OR 23.7, 95% confidence interval 1.63-344.53, P = .02), and MUCP <o=40 cm H(2)O (OR 8.34, 95% confidence interval 1.52-45.65, P = .01) was another risk factor for TOT.
  
  
  CONCLUSIONS
  The risk factors affecting cure after mid-urethral tape procedures were preoperative detrusor overactivity for TVT and TOT and MUCP <o=40 cm H(2)O for TOT.
