Ultrasound imaging of the lower urinary tract after successful tension-free vaginal tape (TVT) procedure. (1/123)

OBJECTIVES: To evaluate changes in the mobility of the whole urethra, in the proximal urethra (funneling) and in the thickness of the urinary bladder wall, after a successful tension-free vaginal tape (TVT) procedure. METHODS: This prospective longitudinal study included 52 women with urodynamically confirmed stress urinary incontinence who had undergone a successful TVT procedure. Ultrasound examination was performed before the TVT procedure and at a median of 3 (range, 3-6) months after surgery. For all women, the changes to the urethra and urinary bladder induced by surgery were examined. For three mobility groups (low, intermediate and high urethral mobility before surgery) we compared the changes induced by the operation and the typical position and mobility of the tape. RESULTS: The position of the urethra at rest was not influenced by surgery. The operation significantly decreased the mobility of all parts of the urethra during Valsalva. The absolute changes of the vector of the urethral movement differed according to the mobility group (average decrease, 6 mm; decrease for women with low, intermediate and high mobility, respectively, 2-3 mm, 4-6 mm and 9 mm). The change in relative mobility was the same in all groups. The operation decreased funneling (width and depth) during maximal Valsalva. After surgery there was an increase in the thickness of the bladder wall (by 0.64 and 0.73 mm, respectively, at the anterior part and trigone). CONCLUSIONS: A successful TVT procedure did not influence the position of the urethra at rest but significantly decreased the mobility of the urethra during Valsalva and also decreased funneling at maximal Valsalva.  (+info)

Role of bladder neck mobility and urethral closure pressure in predicting outcome of tension-free vaginal tape (TVT) procedure. (2/123)

OBJECTIVE: To investigate how urethral mobility and urethral closure pressure affect the outcome of tension-free vaginal tape (TVT) insertion for stress incontinence. METHODS: A total of 191 consecutive women with genuine stress urinary incontinence with or without intrinsic sphincter deficiency were evaluated prospectively with multichannel urodynamics, 24-h voiding diaries, clinical stress tests and introital ultrasound measurements preoperatively and 6 months after surgery. Additional introital ultrasound examinations were performed immediately after the operation, at 12 months and annually thereafter. 177/191 patients had completed a 36-month follow-up at the time of writing. Urethral mobility was described as linear dorsocaudal movement (LDM), with hypermobility being defined as LDM > 15 mm on sonography. Intrinsic sphincter deficiency was defined by a maximum urethral closure pressure (MUCP) of <20 cm H(2)O. RESULTS: The overall cure rate at the 36-month follow-up was 89.5% (Kaplan-Meier estimator), with secondary cure (within 6 months of surgery) in 10.5% of these patients. The operation failed in 4.2% of the women and recurrence was seen in 6.3% of the cases. Bladder neck mobility was significantly reduced at the 6-month follow-up (P < 0.001). Compared with primary cure, therapeutic failure and secondary cure were associated with a significantly lower postoperative bladder neck mobility (P < 0.05). Postoperative hypermobility reduced the risk of therapeutic failure. In addition, women with therapeutic failure or secondary cure had a significantly lower MUCP than did those with primary cure (P < 0.01). CONCLUSION: The effectiveness of the TVT sling appears to depend on adequate postoperative urethral mobility and urethral closure pressure.  (+info)

Surgical technique using AdVance sling placement in the treatment of post-prostatectomy urinary incontinence. (3/123)

OBJECTIVES: To describe and illustrate a new minimally invasive approach to the treatment of male stress urinary incontinence following prostatectomy. SURGICAL TECHNIQUE: Our initial experience consisted of four patients treated with the Advance sling for post-prostatectomy urinary incontinence. Sling placement involves the following steps: 1. Urethral dissection and mobilization, 2. Identification of surgical landmarks, 3. Placement of needle passers through the obturator foramen, 4. Mesh advancement, 5. Mesh tensioning and fixation, 6. Incision closure. COMMENTS: Based on our initial experience, we believe that the Advance Male Sling System may be a safe technique for the treatment of male stress urinary incontinence. This technique is easy to perform and may offer a reproducible, transobturator approach. Further patient accrual is ongoing to assess the safety and reproducibility of this technique. Also, additional study will focus on efficacy standards and complication rates.  (+info)

TVT versus TVT-O for minimally invasive surgical correction of stress urinary incontinence. (4/123)

OBJECTIVE: The present work describes our experience in surgical correction of stress urinary incontinence, comparing both the TVT and the TVT-O techniques. METHOD: Between October 2001 and March 2004, 76 patients underwent the TVT procedure. Between January 2004 and January 2005, 98 surgical corrections of urinary incontinence were carried out using the TVT-O technique. RESULTS: Median operative time was 28 minutes for TVT and 7 minutes for TVT-O. Intraoperative complications for TVT occurred in 4 patients (6.6%): urinary bladder perforation in 3 patients (5%, p=0.0228) and parietal peritoneum perforation in 1 case (1.6%). No intraoperative complications took place during TVT-O. Immediate postoperative complications: transient urinary retention in TVT, 2 cases (2.6%) and overcorrection in TVT-O (1%) which was readjusted within 24 hours. There were no late complications after TVT. There were 2 cases (2.04%) with late complications in TVT-O. TVT and TVT-O resulted in correction of incontinence in 100% of the patients. CONCLUSION: TVT and TVT-O are two effective techniques for the correction of stress urinary incontinence. TVT-O would seem to be a technique much easier to perform resulting in less intraoperative complications.  (+info)

Three-year outcomes of the innovative replacement of incontinence surgery procedure for treatment of female stress urinary incontinence: comparison with tension-free vaginal tape procedure. (5/123)

Innovative replacement of incontinence surgery (IRIS) is a polypropylene tape that is placed beneath the midurethra to restore urinary continence. We evaluated the long-term efficacy and safety of the IRIS procedure and compared it with tension-free vaginal tape (TVT) for the treatment of female stress urinary incontinence. We included all 66 consecutive women who underwent IRIS (n=34) or TVT (n=32) between February 2002 and April 2003 and followed them up for at least 3 yr postoperatively. The 3-yr success rate was 94.1% for the IRIS and 93.8% for the TVT, and the satisfaction rates were 91.2% and 90.6%, respectively. Intraoperative complications for the IRIS group included 3 cases of bladder perforation, and there were 3 cases of bladder perforation in the TVT group. The postoperative complications for the IRIS group included 2 patients with de novo urgency and one patient with mesh erosion. Three patients with TVT developed de novo urgency. One case of each group showed temporary voiding difficulty. On the basis of our results, the IRIS may be an effective and safe procedure as compared to TVT, with a high success rate and a low complication rate.  (+info)

Comparison of retropubic vs transobturator approach to midurethral slings: a systematic review and meta-analysis. (6/123)

To systematically review the literature and to quantitatively compare outcomes and complications following retropubic vs transobturator approach to midurethral slings. We searched PUBMED, OVID, EMBASE, CINAHL, POPLINE, Web of Science, Cochrane Collaboration resources, TRIP, Global Health databases, and abstracts from relevant meetings from 1990 to 2006. We included all studies that compared retropubic and transobturator approaches to midurethral slings and that defined outcomes. We used random-effects models to estimate pooled odds ratios and 95% confidence intervals for objective and subjective failure, complications, and de novo irritative voiding symptoms. Six randomized trials and 11 cohort studies compared transobturator and retropubic approaches to midurethral slings. There was insufficient evidence to support if one approach leads to better objective outcomes. We found no difference in subjective failure between the 2 approaches after pooling data from randomized trials (pooled odds ratio OR 0.85, confidence interval 95% CI 0.38-1.92). The transobturator approach was associated with a decreased risk of complications (pooled OR 0.40, 95% CI 0.19-0.83]). The transobturator approach to midurethral slings is associated with a lower risk of complications; however, it is still unclear if one approach results in superior objective or subjective outcomes.  (+info)

Five year follow-up comparing tension-free vaginal tape and colposuspension. (7/123)

Burch colposuspension has been the procedure of choice for stress urinary incontinence, more recently the tension-free vaginal tape (TVT) has been used. A retrospective study on all TVT's and colposupensions was performed. The present clinical condition was assessed using the Bristol Female Lower Urinary Tract Symptoms and Short-Form 12 questionnaires. The median operating time was 50-59 minutes for TVT and 70-79 minutes for colposupension. The median number of day's hospitalization was 3 and 10 respectively. The overall success rate was 88.5% and 92% respectively. No significant difference in subjective outcome was noted at more than 5 years after surgery between the two procedures for either the BFLUTS or SF-12.  (+info)
