Invitation
paragraph
You are being invited to take part in a research
study. Before you decide, it is
important for you to understand why the research is being done and what it will
involve. Please take time to read the
following information carefully and discuss it with others if you wish. Ask us if there is anything that is not
clear or if you would like more information.
Take time to decide whether or not you wish to take part.
Thank you for reading this.
3. What is the purpose of the study?
3.1 Background
Urinary Stress incontinence is a common condition
which causes a significant impact on quality of life for many women. A large
number of treatment options have been developed over the years and these
different procedures involve various surgical approaches.
The Tension Free Vaginal Tape – Obturator (TVT-O) procedure is a sub urethral sling procedure.
The efficacy of the TVT and similar sling procedures has already been documented. This study aims to investigate the efficacy and safety outcomes in patients who have undergone a TVT procedure using the transobturator TVT-O device. This study aims to document potential safety and efficacy improvements offered by the new TVT-O device.
3.2 Purpose
of the study
The purpose of this study is to determine the success and complication rate for the TVT-O Procedure in the treatment of urinary stress incontinence. In order to determine the incidence of any longterm complications the study will continue indefinitely. You will continue to be looked after by your doctor following the surgery but you will also be contacted independently by our research nurse and asked to complete an evaluation questionnaire.
The safety of the procedure will be determined by
counting the number of problems that occur during the study, such as any pain or discomfort, mesh
complications, infection or more serious problems that might need admission to
hospital.
4. Why have I been chosen?
You were chosen to participate in
the study, because your physician thinks that your urinary stress incontinence
problem is suitable to be treated with a suburethral sling.
5.
Do
I have to take part?
It is up to you to
decide whether or not to take part. If
you do decide to take part, you will be given this information sheet to keep
and be asked to sign a consent form. If you decide to take part you are still
free to withdraw at any time and without giving a reason. A decision to withdraw at any time, or a decision
not to take part, will not affect the standard of care you receive. The study
is only concerned with documenting your future health and success of the
operation. The study does not change any aspect of your treatment.
6. What will happen to me if I take
part?
6.1 General
If you decide to
take part in the study you will be recruited to the study for future follow up.
The research itself will last for several years as we are particularly
interested in the long term outcomes of this procedure.
The TVT-O Device Is used to implant a tape
in a suburethral position which aims to provide longterm relief from stress
urinary leakage. At this stage the outcomes of suburethral slings have been
documented for up to 5 years. We aim to make occasional contact with you and
check your progress by postal questionnaire into the future.
6.2
Recruitment
visit
Before you undergo
the TVT-O procedure your doctor will go through your medical history with you.
You will need to repeat urodynamic and MSU tests if you have not performed them
in the last six months. These are routine examinations done to patients
diagnosed with stress incontinence.
Additionally, your doctor needs to know:
·
If you
have any other urinary symptoms
·
What
past procedures or prescription drugs you have tried
·
If you
have any other diseases or illnesses
·
What
medications you are currently using
You will be asked to fill-in questionnaires and
a bladder diary before your visit to the hospital for a period of 3 days. In
the diary you will be asked to write down your symptoms (drinking and voiding
habits) for 3 consecutive days. A pad test will enable your doctor to determine
the quantity of urine loss each day. This will give your doctor a “baseline”
record of your symptoms prior to treatment. This information will help you and
the doctor to decide whether you are suitable to undergo the Midline IVS surgery.
6.3
TVT-O
Surgery
The TVT-O procedure involves placement of a
polypropylene tape under the midurethra using a special instrument. A small
incision is made under the urethra and the instrument used to pass a plastic
stylet around the urethra and through the obturator fossa. The tape is
permanently incorporated into the tissues under the urethra and is usually
unable to be detected by the patient.
Fig 1: The TVT-O is a polypropylene sling which
supports the mid urethra. The tape is passed behind the inferior pubic ramus on
each side from below.
The risks of the procedure are the usual risks
of surgery which include pain, bleeding, infection, scarring, blood clots,
pulmonary emboli and loss of function. Any pelvic surgery can potentially lead
to bladder, bowel and sexual dysfunction. Patients who undergo a suburethral
sling procedure have a risk of neourgency (a sudden compelling desire to void
occurring for the first time after surgery) and voiding difficulty, both of
which are usually temporary.
The polypropylene tape used in a TVT-O
Procedure is a foreign body. The use
of a foreign body such as a polypropylene mesh tape can be associated with
erosion, infection or rejection of the prosthetic material. This study aims to
determine the true incidence of these problems.
The technique involves passage of a needled
instrument with a plastic tip from a
vaginal incision to an exit point in the groin. Adequate visibility is provided
by a vaginal incision which enables the TVT-O device to reach the pubic ramus
from where it is rotated laterally to exit the skin in the inner thigh. The
TVT-O is slid along the posterior surface of the pubic ramus where it is then
able to exit the obturator foramen under direct visualization.
6.4
Post
Operative Management
In the operating theatre you will be
prescribed antibiotic medication in order to reduce the risk of infection after
the surgery. You can go home the same day if you are feeling OK and you are
passing urine without difficulty.
The TVT-O may cause temporary difficulty
passing urine immediately after surgery so you will be watched closely by the
nursing staff to ensure that you are emptying your bladder. An ultrasound may
also be performed in the ward to ensure that your bladder is completely
emptied.
6.5
Follow
up visits
You will be
asked to attend follow-up visits 1, 3, and 12 months after the surgery. Each visit will last approximately
20 minutes at your doctor’s clinic. During these visits, you will be asked to
fill in some questionnaires to chart your progress. Additionally, you may discuss
your symptoms with your doctor and decide whether any further investigation or
management is necessary.
Once the study is over you will continue to be followed up by your
doctor.
7. What do I have to do?
Once you and your doctor have decided that
surgery is appropriate you will have the opportunity ask any questions and
discuss your options. If you go ahead with surgery you will be given the option
to withdraw either from the surgery or the study. If you decide to proceed with
the study you will be asked to sign this consent form.
7.1
Lifestyle
limitation
As with any surgery you should let your body heal. Right after the surgery you should “take it easy “and avoid lifting heavy things, stretching and avoid causing strain on the tape and abdominal stitches. You will be asked to follow a strict postoperative routine for the 7 days. This involves:
a. No house work.
b. No cooking – light meals only.
c. No exercising – no bending down or stretching up.
d. You may walk around the house but not out of doors.
e. No driving or riding in a car.
f. No douching.
g. No sexual intercourse.
h. No straining – YOU MUST NOT GET CONSTIPATED.
i. Empty your bladder frequently.
Once you have completed 1 week of severe restriction outlined above you will be allowed to return to normal activity but for 2-3 months you should avoid any strenuous exercise or activity.
7.2
Effect
on Other Medical Conditions
A TVT-O procedure has no implications for any
medical conditions other than pregnancy where choice of mode of delivery may be
affected by the presence of a polypropylene suburethral tape. The tape becomes incorporated in the fibrous
tissue of the pelvis and usually can not be identified at subsequent surgery.
7.3
Home
or occupational environment
During the
initial recovery phase you must limit your activities. Your regular day routine
will be limited by the need to avoid any activity that could potentially move
or damage the tape.
This means that you will be discouraged from performing any domestic duties in
the first two weeks after surgery.
8. What is the treatment that is being
studied?
The
TVT-O is a form of suburethral sling used to treat urinary incontinence.
9.
What
are the alternative therapies?
There are a
large number of treatments available for stress incontinence. These include:
· Pelvic floor exercises
· Abdominal surgical procedures (Burch, Marshall Marchetti)
· Vaginal repair surgery
· Needle suspension procedures.
· Laparoscopic colposuspension procedures
· Other suburethral slings (TVT, IVS, SPARC, Monarc)
Your doctor will be happy to provide any information of these alternatives if you wish.
10.
What
are the side effects of any treatment received when taking part?
The potential side effects related to this study listed below are the usual side effects of incontinence surgery.
· Minor wound discomfort or pain
· Urinary tract infection
· skin irritation
· blood clotting
· anaesthetic complications (allergy or sensitivity to anaesthetic drug, breathing arrest, etc.)
· bladder perforation or damage during the procedure
· temporary difficulty passing urine after the procedure
· urinary urgency or urge incontinence
· development of vaginal prolapse
· possible sexual dysfunction
· reactions to the mesh used to make the TVT-O sling resulting in erosion, rejection or inflammation. .
.
In any case, whenever you feel an unusual or
unexpected event or you experience less control of your symptoms or you
becoming concerned, you should contact your doctor or nurse (detailed below).
11.
What
are the possible disadvantages and risks of taking part?
There are no additional risks associated with entering this study, but there are risks associated with undergoing surgery.
If you sustain any damage to you bladder during your surgery you will need a catheter for 24-48 hours to allow healing to occur.
If you have any problems passing urine after the operation you may need to use a catheter temporarily.
If you suffer a wound or urinary tract infection you may need antibiotic therapy.
Close attention will be paid to the development of any problems or complications which could be related to the placement of your TVT-O tape. Any new information regarding your medical condition will be recorded in the study files; however, your identity will remain confidential.
12.
What
are the possible benefits of taking part?
We do not
believe that there is any specific benefit to you personally taking part in
this research. However, there is a benefit to your symptoms as a result of
undergoing the TVT-O procedure as results from past studies show that a
suburethral sling is an effective cure for stress incontinence.
We hope that the treatment will help you, although this cannot be guaranteed. The information we get from this study may help us to provide better treatments for patients in the future.
13. What if new information becomes
available
Sometimes during the course of a research project, new information becomes available about the treatment that is being studied. If this happens, your research doctor will tell you about it and discuss with you whether there are any implications for your care.
14.
What
happens when the research study stops?
At all times during and after the study you will be followed-up by your doctor.
15.
What
if something goes wrong?
Your right at
law to claim compensation for injury where you can prove negligence is not
affected by participation in this study.
16.
Will
my taking part in this study be kept confidential?
If you consent
to take part in the research, any of your medical records may be inspected by
team of doctors undertaking the research for purposes of analysing the results.
They may also be looked at by the hospital administration, the ethics committee
and from regulatory authorities to check that the study is being carried out
correctly. Your name, however, will not be disclosed outside the hospital/GP
clinic. Your own GP
will be notified regarding your participation in this study.
17.
What
will happen to the results of the research study?
