Female UrologyRisk Factors Affecting Cure After Mid-urethral Tape Procedure for Female Urodynamic Stress Incontinence: Comparison of Retropubic and Transobturator Routes
Section snippets
Material and Methods
All female patients with urodynamically proven stress incontinence (USI) who had completed the preoperative urodynamic studies and pad testing and underwent the TVT procedure (using TVT from Ethicon, Somerville, NJ) or the TOT procedure (using Monarc TOT, American Medical Systems, Minnetonka, MN) at National Taiwan University Hospital from January 2004 to February 2007 were studied in a retrospective fashion. All procedures conformed to those described in previous reports1, 2, 12 and were
Results
A total of 61 patients who underwent the TVT procedure and 60 patients who underwent the TOT procedure were included in the present study. All patients (n = 121) were followed up at our hospital for >12 months. Except for the maximal urethral closure pressure (MUCP), operating time, and symptoms of voiding dysfunction (ie, straining to void [n = 5], incomplete emptying [n = 4]), no significant differences were found in the baseline clinical, urodynamic, or perioperative characteristics between
Comment
Using the stress cough test and subjective report of urine leakage, the cure rate in the TVT group was comparable to that of the TOT group (82.0% vs 78.3%, P = .57) despite the lower preoperative MUCP value for the TOT group. The cure rates for both procedures used in this study were within the previously reported ranges.3, 4, 5, 6
In the present study, a MUCP of ≤40 cm H2O was an independent risk factor for the failure to be cured after the TOT procedure, but not after the TVT procedure.
Conclusions
The presence of preoperative detrusor overactivity was an independent risk factor for the failure to be cured after TVT procedure. The presence of preoperative detrusor overactivity and a MUCP of ≤40 cm H2O were independent risk factors for the failure to be cured after the TOT procedure.

2016, Taiwanese Journal of Obstetrics and GynecologyCitation Excerpt :However, very few patients had MUCP of < 20 cmH2O. Since women with LUCP have been associated with the increased failure of incontinence surgery [8,9], and a low MUCP of < 42 cmH2O [10] and < 40 cmH2O [11] have been found to be significant risk factors affecting the treatment outcome, we categorized patients using a cut-off MUCP value of 40 cmH2O to define low urethral closure for the purpose of this study. Although this grouping does not follow the standard outlined by the ICS, the observations made in comparing the two patient groups remain valuable.

2015, Gynecology and Minimally Invasive TherapyCitation Excerpt :Richter et al36 found risk factors for overall failure were previous SUI operation, Q-tip test <30°, severity of urge symptoms, and a high preoperative pad weight. Hsiao et al37 concluded that risk factors for recurrence can be the preoperative detrusor overactivity after TVT, lower maximal urethral pressure and < 40 cm H2O after TOT. Similar results by Houwert et al38 in a retrospective cohort study determined the low maximal urethral closure pressure and mixed UI as risk factors for failure after TOT.
