Stress IncontinenceThe involuntary loss of
urine during coughing,
laughing, sneezing or other activities that
increase abdominal
pressure

Stress Incontinence-ISD
INTRINSIC SPHINCTER DEFICIENCY
The urethral sphincter is
unable to close and generate
enough resistance to retain
urine, especially during stress
maneuvers.

Stress Incontinence-ISD
HYPERMOBILITY
The bladder neck and
urethra are significantly
displaced with anincrease in abdominal
pressure

Pathophysiology of GSUIDefects in the Support Structure
Pubourethral ligaments
Suburethral vaginal hammock(endopelvid fascia)
Connective tissue (collagen fibers) interconnecting theabove structures
Defects in Both Instrinsic andExtrinsic Urethral Function:
DenervationDevascularization

Dr. Neale¶s QuoteThe art of urogynaecology is to 'marry' the right
operation to the right patient, Meaning '... after the
right patient has been selected for operation, the
right operation must be selected for the patient.¶

Goal of SurgeryRestore and/or reinforce the pubourethral
ligaments
Restore and/or reinforce the suburethralvaginal hammock.
Reinforce the paraurethral connective
tissue.

ProphalacticTVT as Combined
Therapy for Severe Prolapse
30 consecutive continent women withsevere prolapse and occult SUI(+stress test)
All patients had hyper-mobility(no ISD)
One year follow-up with CMG at 3 monthintervals
0 developed postop symptomatic SUI
3(10%) asymptomatic patients had positivetests
9(30%) had detruser instability before
surgery that persisted in 6(66%) post-op

Combined Therapy(Cont.)
Postop de novo detruser instability found in
4 other patients
None of the patients had recurrent prolapse
None had bladder outlet obstruction
Conclusion, preliminary results indicate
prophalactic TVT encouraging for severe
prolapse surgery

Long Term Results with TVT for
Mixed and Stress IncontinenceQuestionnaire returned from 760 patients out of 970 who
had TVT 2-8 years previous
Excluded 17 as unclassified, and 51 as de novo-
580(83.8%) with stress and 112(16.2%) mixed
Results: Stress cure rate of 85%, mixed cure rate of 60%
up to 4 years then declined to 30% after 4 years due to
urge

Anesthesia(s) Effect on
Voiding after TVTRetrospective study of 173 cases(data only
from 163) comparing general anesthesia vs.
local anesthesiaResults: General anesthesia(lack of cough-
stress test) does not increase chance of post-
op failureMurphy et al, Louisville, Obstetrics and Gynecology, 101, April, 2003

Urinary Retention after TVT1998-600 TVT procedures had 17 patients(2.8%)
with urinary retention more than 1 week post-op
All 17 had sling release procedure(64 days mean post-op)
15 minute procedure with minimal blood loss
Results: 1 urethral injury, 16 remained dry

Urethral Erosion After TVT:
Case Report
57 year old with urinary retention 1 year post TVT
Fluroscopy showed dilatation and obstruction
Cysto showed erosion of slingAuthor thought erosion due to urethral tension and
repeated catheterization

Management of Vaginal Erosion
of Polypropolene Mesh Slings
90 patients had SPARC between 10/2001-10/2002
3 SPARC and 1 transferred TVT had mesh exposure
6 weeks post-op: 2 asymptomatic, 2 symptomatic
Conservative management 100% cure in 3 months
Therefore, not all erosion need completely removal.

Ilioinguinal Nerve Entrapment
after TVT
Entrapment seen often after herniorrhaphy,inguinal node dissection, and appendectomy
Found entrapment after TVT on 68 year oldfemale and treated with local injections
More likely to occur when trocar extendsinto internal oblique muscle/beyond the
lateral edge of the rectus where nerve runsGeis, Dietl, Germany, Int. Urogynecol J., 13, 2002

³Physician Satisfaction with SPARC Suprapubic Sling System: An Opinion-based survey´, Stanford E., J
Pelvic Med Surg, 2005
Opinion-based survey based on completed surveys by 47 urogyns and urologists
76% reported that the SPARC was less difficult to adjust than TVT
90% found the adjustment allowed by SPARC's suture is of at least some benefit
A paired, one-way t-test demonstrated that blood loss with SPARC was 10% less than that of TVT
