TVT position relative to the patient's urethra seems to play a role in treatment outcome. Outcome was best in patients with dynamic change in tape shape during straining and location of the tape at the junction between the lower and middle urethra and at least 3 mm from the urethral lumen.
Introduction and hypothesisThis study evaluates the relevance of the tape position and change in shape (tape functionality) under in vivo conditions for mid-term outcome.MethodsChanges in the sonographic tension-free vaginal tape (TVT) position relative to the percentage urethral length and the tape–urethra distance were determined after 6 and 48 months in 41 women with stress urinary incontinence.ResultsAt 48 months, 76% (31/41) of women were cured, 17% (7/41) were improved, and 7% (3/41) were failures. Disturbed bladder voiding was present in 12% (5/41), de novo urge incontinence in 7% (3/41). The median TVT position was at 63% of urethral length. Median tape–urethra distance was 2.7 mm, ranging from 2.9 mm in continent patients without complications to 1.1 mm in those with obstructive complications. Patients with postoperative urine loss had a median distance of 3.9 mm. The tape was stretched at rest and C-shaped during straining in 15 of 41 women (37%) at 48 months (all continent). Patients with this tape functionality at 6 months were also cured at 48 months in 86% of cases (19/22), and only 14% (3/22) showed recurrent incontinence.ConclusionsMid-term data suggest an optimal outcome if the tape is positioned at least 2 mm from the urethra at the junction of the middle and distal thirds. Patients with optimal tape functionality at 6 months are likely to show mid-term therapeutic success.
Aims: To assess the effectiveness of a polyacrylamide hydrogel (PAHG; Bulkamid 1 ) in treating recurrent stress urinary incontinence (SUI) following a previous midurethral sling (MUS) implant. Methods: This observational study, conducted since 2009, included 60 patients with recurrent SUI or mixed urinary incontinence (MUI) after a previous MUS and who chose to be treated with PAHG. Objective and subjective outcomes were assessed at 1, 6, and 12 months after the initial injection. Patients were classified as cured based on a negative cough test (supine and standing) and <2 g urine on 1-hr pad test and a VAS score improved by !90%. Improved were those with the loss of only a few drops of urine during the cough test and 2-10 g urine on 1-hr pad test or a reduction >50% compared with preoperative urine loss and a VAS score improved by !75%. Results: The volume of PAHG injected in the current study ranged from 1-3 ml. Cured/improved rates were 93.3% (56/60), 88.3% (53/60), and 83.6% (46/55) at 1, 6, and 12 months, respectively. Patients with MUI had a cured urgency urinary incontinence rate of 36.8%, 47.4%, and 38.9%, respectively. Voiding dysfunction rates were 13.3% (8/60), 8.3% (5/60), and 1.8% (1/55) at 1, 6, and 12 months and urinary tract infection rates were 5% (3/60), 11.7% (7/60), and 3.6% (2/55), respectively. Other adverse events were short-term and/or observed in <4% of patients. Conclusions: PAHG can be used to treat recurrent SUI after MUS failure with good outcome and low complication rates.

When surgically treating SUI with a TOT, incision at the mid-urethra using the 1/2 rule is recommended as it leads to better outcomes for most patients, particularly those with normal urethral mobility.
