AUA STRESS INCONTINENCE GUIDELINE COMMITTEE:

META-ANALYSIS OF THE LITERATURE:

SLINGS ARE MORE DURABLE AND HAVE A HIGHER SUCCES RATEBUT A HIGHER INCIDENCE OF VOIDING DYSFUNCTION

Evidence based analysisEvidence based analysis“efficacy”“efficacy”

• interview / questionnaire / chart / examination / UDS

• accuracy and reliability of the survey instrument

• accuracy and reliability (bias) of patient or interviewer

• “moment in time” : info obtained vs. published

• follow-up: time (minimum / average / range) & dropouts

•

• Quality of life: SF – 36• Bristol• King’s College• SEAPI• others

Evidence based analysis“quality of life”

• what is the complication rate?• is the symptom persistent, exacerbated, or new?• how bothersome to the patient? will it resolve?• if not, what is the nature of the corrective treatment?• if it is medicine: will it be chronic?• if it is surgery, how difficult for the patient?

Evidence based analysisEvidence based analysis“tolerability - complications”“tolerability - complications”

• what is the “gold standard” / does it exist?• is the old or new technique reproducible?• how is one operation compared to another?• retrospective vs prospective? randomized?• who is doing the procedure? individual or group?• is there a learning curve? • are the complications similar?

Evidence based analysis“comparisons of operations”

Evidence Based AnalysisEvidence Based Analysis

• Follow-up “drop-outs” “exclusions” “intent to tx”

• Patients lost to follow-up may have > complication rate•• Complaints that are omitted because of insufficient data

• Patients who refuse surgery may bias outcome

• How does the patient know the alternative treatment ?

A Randomised Trial of A Randomised Trial of Colposuspension and TVTColposuspension and TVT

• Prospective randomized 14 center study• 344 patients 15 month period, ending Aug. 1999

• Methodology - meas. questionnaire; freq. / vol. chart, filling / voiding cystometry, urethral pressure profilometry, ICS 1hr. Pad test, SF-36, EuroQol, Bristol FLUTS questionnaire.

• Measures - Pre-Op, 6 mo., 12 months, 24 month

• Evaluable Patients at 24 mo. - 137 TVT vs. 108 Burch

A Randomised Trial of A Randomised Trial of Colposuspension and TVT Colposuspension and TVT

• Cure rates and quality of life changes

• TVT remained comparable with colposuspension at 24 months

• Economic considerations Surgery details show TVT to be less expensive

due to shorter time and duration of treatment anesthetic room, OR time, recovery room, hospital stay, and hemoglobin during the operation

* As of April 15, 2002, 5 deaths have been reported to GYNECARE that are associated with TVT..

Most Serious Reported Complications* (based on over 200,000 patients treated world-wide)

The Relationship of TVT Insertion to the Vascular Anatomy of the Retropubic Space and the Anterior Abdominal Wall

• Study performed on 10 fresh cadavers • Measured distance from the needle to vessel• • Results: All vessels were lateral to the needle

• Conclusion: “If the TVT needle is laterally directed or externally rotated in the course of insertion, major vascular injury may result”
