Test for detecting stress incontinence-
Bonney’s test : In this test the is patient asked to insert two fingers , in the paraurethral region and the bladder
neck is lifted up, and then the patient is asked to cough. If SUI gets corrected , then it is due to bladder neck
desent .If SUI persists, it is due to sphincter defect.Marchetti test : is same as Bonney’s test, except that instead of fingers, two Allis forceps are used.
Q tip test : A sterile cotton swab is introduced into the level of bladder neck. Then the patient is asked to
strain.Marked upward elevation of cotton tip (>30°) indicates urethra hypermobility. Goniometer is used to measure
the urethero – vesicle angle.
Cystometry – Main objective is to rule out urge incontinence.
Normal Values:
• Residual urine less than 50mL
• First desire to void between 150 and 200mL
• Capacity of strong desire to void more than 400mL
• No detrusor contractions during filling despite provocation
• No leakage on coughing or on any provocation
• Voiding by voluntarily initiated and sustained detrusor contraction
• Flow rate during voiding more than 15mL/sec with a detrusor pressure less than 15cm of water during filling
and less than 70cm of water during voiding
Abnormal cystometry
If there is leak of urine in the absence of a rise in detrusor pressure, stress incontinence is diagnosed. Urge
incontinence is diagnosed during the filling phase if there are spontaneous or provoked detrusor contractions
while the woman is trying to inhibit micturition. Thus stress incontinence is actually a diagnosis by exclusion.
Management:
1st line of mgt: Pelvic floor exercise called as kiegels exercises.
Definative management : Surgical management.
The choice of surgery is usually between a retropubic urethropexy and a sling operation. These are the currently
employed first line operations for stress incontinence. In general with concomitant prolapse a vaginal route is
preferred and sling surgery is done. If the woman is undergoing a laparotomy for any other reason urethropexy is
preferred. This can also be done laporoscopically.
Retropubic Urethropexy (Abdominal Procedure)
It involves attaching the fascia around the urethra and bladder neck to a supporting structure in the anterior
pelvis. This elevates the blader neck to an intra-abdominal position. The main problem is postoperative voiding
dysfuncion, detrusor overactivity and pelvic organ prolapse.
Two types of surgeries can be done in retropubic urethropexy-
A. The Burch colposuspension-most commonly done urethropexy wherby the fascia at the level of bladder
neck are attached to the iliopectineal ligament or Cooper’s ligament. The success rates are as high as 90%.
B. The Marshall-Marchetti-Krantz or MMK involves attachment of the periurethral facia to the back of the pubicsympysis. A complication specific to this procedure is osteitis pubis and hence this procedure is no longer
used.
Sling operations
A sling is passed around the bladder neck and urethra and attached above to the anterior rectus facia so that a
supporting hammock is created for the urethra. The urethra is supported and also occluded when the intra-
abdominal pressure is increased, examples of this technique are-

Tension free vaginal tape (TVT) and Trans Obturator Tape (TOT): Both TVT and TOT are currently being
widely used as primary operations for stress incontinence.
In TVT-a propylene mesh is placed at the midurethra through retropubic space whereas in TOT it is passed
through a midurethral vaginal incision medial to obturator foramen instead of through the retropubic space.
Note : The most common complication of TVT is bladder perforation(5%), most serious is bowel or vascular
injuries (both

Investigations
1. Urine culture (to rule out infection)
2. Cystourethroscopy (to rule out causes like bladder tumor/calculus)
3. Cystometry
Management:
Urge incontinence is best treated by behavioural therapy and anti cholinergic drugs. (To decrease detrusor
contractions).
Anti cholinergic used are:
1. Tolterodine
2. Hyoscyamine
3. Oxybutynin
4. Dicyclomine
So friends now with this background – lets get on to the Q’s on fistulas and incontinence.
EXPLANATION & REFERENCES
1. Ans. is c i.e. Obstructed labour Ref. Shaw 15/e pg -184; William Gynae. 1/e, p 573
“In developing countries, 90% of genito urinary fistulas arise from obstetric trauma, specifically from
prolonged or obstructed labour.” ... William Gynae. 1/e, p 573
Most common Genital Fistula is vesico vaginal fistula and so above statement holds good for VVF also.
The fistula resulting from pressure during long and difficult labour always involve the trigone of the bladder Q .
Whereas – “In developed countries, latrogenic injury during pelvic surgery is responsible for 90% of VVF.
In industralised countries, hysterectomy is the most common surgical cause of VVF, accounting for
approximately 75% of fistula cases. Laparoscopic hysterectomies were associated with the greatest
incidence followed be abdominal and vaginal.” ... Williams Gynae. 1/e, p 573

MC cause of Recto Vaginal fistula Cesarean perineal tear Q
2. Ans. is d i.e. Uretero vaginal fistula Ref. Jeffcoate 7/e, p 263, 265
• Continuous dribbling of urine following hysterectomy points towards urinary fistulas as the diagnosis.
• In case of urinary fistulas, if the patient never needs to void as there is continous dribbling it signifies that the
fistula communicates with the bladder. If, there is filling and emptying of bladder along with the fistula, it suggests
a fistula opening into one ureter i.e. Uretero vaginal fistula.Q
• As far as urethral fistula are concerned, they give little trouble because the urethra is normally empty of urine.
However during micturition urine passes through the fistula and may then fill the vagina to dribble during body
movements for a short time afterwards.
• This patient is developing symptoms on the seventh day can be explained by : “Fistulas resulting from
accidental, surgical and obstetrical trauma are produced in two ways. They can be caused by direct injury
such as cuts and then they manifest themselves immediately by hematuria and incontinence. Alternatively
if they are the outcome of pressure necrosis or of ischemia, in such a case urinary incontinence, fever and
burning micturition develops 7-14 days after the accident.” ...Jeffcoate 7/e, p 263

Before concluding let’s rule out other options as well :
• In stress incontinence, dribbling of urine occurs only when intrabdominal pressure is raised.
• In urge continence the patient has urge to void urine at a moment’s notice and she is unable to control her
bladder and passes urine instantly.
3. Ans. is c i.e. Foley’s Catheterisation Ref. Shaw 15/e pg -185; Dutta Gynae 5/e, p 404
“Urine culture is mandatory before surgery and infection should be treated. The urine is collected by
Catheterisation.” ... Shaw 14/e, p 167
In VVF
“Preoperative collection is best to be done through ureteric catheterisation.” ... Dutta 5/e, p 404
So friends undoubtedly – Ureteric catheterisation. (Don’t get confused – it is not Foley’s catheterisation) is the
best method for collecting urine for culture in a case of VVF. This option is not given, so, we will have to look for
next best option.
• “Urine collected through a sterile vaginal speculum will not serve the purpose because of contamination.
... Dutta Gynae 5/e, p 405 (Option “d”)
• ‘Midstream clean catch’ sample is also contaminated in vesicovaginal fistulas. (Option “b”)• Supra pubic aspiration done after proper cleansing and draping the patient with full bladder, is easy and next
best method of urine collection after ureteric catheterization. But the only prerequisite for this method of collection
is ‘A full bladder’ which cannot be fulfilled in a case of VVF as urine continuously dribbles from the vagina and
therefore bladder is never full. (Ruling out Option “a”)
By exclusion our answer is Foley’s catheterization, although chances of contamination are present in Foley’s
catheterization but they can be reduced if proper vaginal douching is done prior to collection of urine.
4. Ans. is b i.e. Cystoscopy
5. Ans. is c i.e. Cystoscopy
Ref. Principles & Practice of Obs & Gynae Vol. II for P-G’s 3/e by Pankaj Desai, Narendra Malhotra p 613, Telinde
9/e,p1104
According to Dutta Gynae and Shaws –
Most useful test for fistula is the 3 swab test and cystoscopy is not routinely done.
But according to higher textbooks – (Like Principles & Practice of Obs & Gynae for P.G 3/e by Pankaj Desai )
Evaluation of any fistula includes 3 steps –
A. Clinical Examination – which includes:
a. Pelvic Examination
b. The three swab vaginal test – It helps in diagnosing fistula and differentiating between the other varieties of
fistula
B. Imaging study – It serves three functions.
a. To ascertain that there is no ureteric involvement either during initial injury or due to subsequent fibrosisb. To examine the surrounding tissue planes for abscess formation or unresolved urinoma.
c. To search for residual malignancy in a post radiation fistula
A spiral CT with 3D reconstruction is now the standard of care.
C. Cystoscopy –
“Cystoscopy is indispensable.”

Cystocopy is useful for knowing the:
• Number and size of VVF, with their exact localion in relation to the ureters and bladder neck.
• The state of the margins of the fistulas – If needed a biopsy can be taken from the margin of a post radiation
fistula.
6. Ans. is c i.e. 3 months
7. Ans. is a i.e. VVF Ref. Shaw 15/e pg -186, 187; Dutta Gynae. 5/e, p 405
Management of VVF is : Surgical management :
Timing of surgery –
(a) Small urinary fistulas sometimes heal spontaneously during the first few weeks.
(b) However in a case of established fistula – it is better to wait for about 3 months Q for all tissue inflammation to
subside. If one attempt fails to heal fistula, second attempt is done after 3 months.Q
C) In fistulas following surgery waiting period is 3-6 months.
(d) In fistulas following radiation : 6 months to 2 years time can be taken before inflammation subsides.
Techniques of Repair –
• Layer technique
• Latzko procedure(for fistulas following hysterectomy)
• Chassar Moir technique.Q
Postop Management –
• Continuous bladder drainage for 14 daysQ .
• Antibiotic coverage.
• No vaginal examination, P/S, intercourse x 3 months.
• Avoid pregnancy for 2 years.
• In pregnancy after repair of vaginal fistula – elective cesarean is done.Q
Extra Edge :
This question is an old one so here answer will be 3 months but if this question is repeated now remember the
following lines from Williams Gynae. 1/e, 575 - 576 :
“Timing of repair : Traditional teaching recommends delayed repair of fistulas at 3 to 6 months afte injury.
However, this old dictum is probably no longer applicable. Most agree that unless there is severe infection or
acute signs of inflammation, waiting is not necessary . Early surgical intervention of uncomplicated fistulas does
not affect closure rates, yet appears to reduce social and psychological patient distress (Balivas, 1995). Fistulas
identified within the first 24 to 48 hours postoperatively can be safely repaired immediately with success rates of
90 to 100 percent.”
8. Ans. is b i.e. Uretero – vaginal fistula Ref. Dutta Gynae. 5/e, p 403, Shaw 15/e pg -186
The three swab test helps to confirm the Vesico Vaginal Fistula and to differentiate between vesico vaginalfistula, uretero vaginal and urethrovaginal fistula.
Procedure of Three swab test – A catheter is introduced into the bladder through the urethra.
Three cotton swabs are placed in the vagina as follows :
• One at vault,
• One at the middle
• One just above the introitus.

Methylene blue dye is instilled into the bladder through a rubber catheter and swabs are removed for
inspection.
Observation Interpretation
1. Upper most swab soaked with urine but unstained with dye Uretero – vaginal fistulaQ
2. Upper and lower swab remain dry but the middle swab soaked with dye Vesico – vaginal fistulaQ
3. The upper two swab remain dry but lower one soaked with dye Urethro – vaginal fistulaQ
9. Ans. is d i.e. Below cardinal ligament where uterine artery crosses
10. Ans. is b i.e. Peristaltic movement Ref. Studd progress in Obs and GynaeVol 16 p 306
The crossing of the uterine vessels and ureter is at the level of internal os. Over here the ureter runs below the uterine
vessels (water below the bridge)and the distance between the ureter and uterine vessels is only 1.5 – 2 cm.
The ureter can get injured at all the sites mentioned in the question but during gynaecological surgeries the commonest
site of injury to ureter is where it crosses below the uterine arteries.
The next common site of injury is behind the infundibulopelvic ligament at the pelvic brim.
At operation ureter is recognized by :
1. Its pale glistening appearance
2. By a fine longitudinal plexus of vessels on its surface
3. More particularly by its peristaltic movement
4. By palpation between finger and thumb as a firm cord which, when escapes, gives a characteristic ‘snap’.
Absence of pulsation does not serve to identify a structure as ureter because veins and obliterated umblical artery
are also non pulsatile.
11. Ans. is b i.e. 40% heal spontaneously
Ref. Dutta Gynae 5/e, p 409-410; Telindes; Operative Gynaecology 9/e, p 1088 - 1089; Dew Hursts 7/e, p 543;
Shaw 15/e pg -187
• Uretero vaginal fistula most commonly follows trauma during pelvic surgeries like Total Abdominal Hysterectomy,
Wertheims hysterectomy and Vaginal hysterectomy.
Symptoms :
• Escape of urine through the vagina (True incontinence)Q
• Besides incontinence patient has also got the urge to pass urine and can pass urine normally.Q
• Patient may complain of :
– Flank pain
– Temperature
– Retroperitoneal fluid collection (caused by urinary leak into the abdominal cavity due to transection of the
ureter i.e. option ‘a’ is correct).
Investigation :1. Three swab test differentiates it from VVF.
2. I.V. Indigocarmine test : if the urine in the vagina is unstained following three swab test, indigocarmine is
injected intravenously, if urine becomes blue diagnosis of uretero – vaginal fistula is confirmed.
3. IVP : In case of ureteric transactions partial or complete, pyelography fails to show part or whole of the ureter
on the transected side and there may be pooling of dye in the peritoneal cavity.
4. USG : Following ureter ligation, USG may reveal hydronephrosis and dilated ureter proximal to the site of
block.
5. CT scan.

Management :
Time of Repair -
• Ureteric injury/ureteric fistulas must be repaired as soon as the diagnosis is confirmed.
“The best chance of healing with primary repair is when reoperation is done within the first 48 hours. Our
opinion is that some form of immediate intervention must be undertaken no matter what the type of injury
has occurred”. ... Telinde Operative Gynecology 9/e, p 1088
“Uretero vaginal fistula should be repaired as early as possible to prevent upper urinary tract damage”
... Dewhurst Obs. & Gynae. 7/e, p 543
Technique of Repair –
a. When ureteral sheath is denuded for a short segment, it is best to do nothing.
b. When ureter is kinked due to a suture, it should be removed or deligated immediately.
c. If clamped tissue is healthy and viable, splinting/stenting is done for 7-10 days for further.
Ureteric transection :
a. Ureteroneocystostomy (implantation of ureter into the bladder) when injury is near bladder.b. Uretero ureterostomy : end to end anastomosis : done when ureter is dissected above mid pelvis.
c. Bladder flap operationQ (MODIFIED BOARI’SQ ) : done when ureter is short or injury is at the level of pelvic brim.
d. Segment of small intestine may be used for repair.
12. Ans. is c i.e. Vesico uterine Ref. Shaw 15/e pg -188; Jeffcoate 7/e, p 266
13. Ans. is b and c i.e. UVF (Uterovesical fistula) and Bladder endometriosis Ref. Shaw 15/e pg -188
The condition of cyclical passage of menstrual blood in urine is called as Menouria. ... Jeffcoate 7/e, p 266
Menouria :
• It is seen in uterovesical fistulaeQ
• Usually follows caesarean sectionQ
• The patient complains of hematuria/passage of menstrual discharge via urethra at the time of menstruation.
Patient does not have Urinary incontinence.Q
• Mensouria is seen when Utero vesical fistula opens into the uterus above the isthmus.Q
• The presence of the fistula can be demonstrated by hysterography (but not by cystography) and cystoscopy.Q
• Treatment is by abdominal repair.Q
• Another Important cause of cyclical hematuria is endometriosisQ of bladder.
14. Ans. is a i.e. Colostomy
Ref. Novak 14/e, p 704; 15/e p 711, Sabiston T.B. of Surgery 17/e, p 1500; Washington Manual of Surgery 3/e, p 279
Rectovaginal fistula is a communication between the epithelium lined Q surfaces of the rectum & the vagina.
Diagnosis :
• History of passing flatus, stool, mucus or blood per vagina.
• Diagnosis is made usually with :
– Speculum examination (P/S)
– Anoscopy / Proctoscopy
– Methylene blue enema

• Endoanal ultrasound can determine the severity of trauma.
Classification :
Congenital Acquired
– due to congenital abnormalities – Trauma
– Inflammatory bowel disease
– Irradiation
– Neoplasia
– Infection
– Other causes
Now lets talk about Rectovaginal fistula that results due to obstetric injury :
Initial Treatment : A small rectovaginal fistula may be managed with conservative medical approach, in hope that
decreasing the fecal stream will allow closure of fistula. Large rectovaginal fistula for which there is no hope of
spontaneous closure, are best managed by performing initial diverting colostomy.Q
Ref. Novak 14/e, p 704; 15/e p 711
Definitive Treatment : However the initial management is either medical conservative approach (small fistula) or
a diverting colostomy (large fistula) to allow for the pelvic inflammation to subside, but the definitive treatment is
surgical repair.
If even after several months (3-6 months) of conservative approach Fistula does not heal, surgical repair is done.
15. Ans. is d i.e. Injury to hypogastric plexii Ref. Jeffcoate 7/e, p 857
Retention of urine in females can be explained by one of the four mechanisms.

16. Ans. is a i.e. Pelvic Floor muscle Exercises
Ref. Dutta Gynae 5/e, p 586; Novak 14/e, p 875; Williams Gynae 1/e, p 525-526, Textbook of gynae, sheila
balakrishnan 1/e, p328
The most recommended non surgical treatment for stress incontinence is Pelvic floor muscle exercise.
“Pelvic floor muscle training should be offered as first line conservative management for stress
incontinance.” ... Novak’s 14/e, p 875; Dewhurst 10/e, p 486
“Pelvic floor exercises are the mainstay of conservative therapy for stress incontinance.”
... Urinary incontinence in primary care’ (2000)/73
Conservative management options for Stress Incontinance
• Pelvic floor muscle training exercises/Kiegels exercises (Mainstay/First line of management)
• Vaginal cones/Weights (also help strengthening the muscles)
• Electrical stimulation (alternative to pelvic exercises)
• Bladder training/Scheduled voiding (most useful for urge incontinence)
• Biofeedback
• Pharmacotherapy
– Duloxetine (First drug specifically developed and licensed for this indication. It is a selective serotonin and
norepinephrine reuptake inhibitor.)
– Tricyclic antidepressants
– α adrenergics (eg ephedrine)-to increase the tone of urethra.Main problem with these drugs is that theycan lead to hypertension.
– Estrogens (to be given in postmenopausal women who are atrophic)
Also know
• Avoiding Caffiene and carbonated drinks helps to control urine frequency and urgency.
17. Ans. is 17 is – a i.e. Stress incontinence
Ref: Shaw 14/e. p 174, Textbook of Gynae shiela Balakrishnan 1/e.p 330
As discussed in preceeding text, kellys plication/Kelley’s stitch was the standard first line of treatment for SUI
previously but due to low cure rates, it is not being done these days. 5 year failure rate for kellys plication is
approximately 50%
18. Ans. is a i:e Stress urinary incontinence Ref. Telinde 9/e, p 1035-1037
Bonney’s test is performed in the clinical evaluation of SUI. In the Bonney’s test, two fingers are placed in the
vagina at the UV junction on either side of the urethra and the bladder neck is elevated.
On straining or coughing, leakage of urine indicates of positive test. A positive test indicates that the SUI is due to
bladder neck descent and urethral hypermobility and can be corrected by bladder neck suspension surgeries.
A negative test i.e. leakage of urine-means SUI is due to intrinsic urethral sphincteric deficiency and results of
performing bladder neck suspension surgery will not be good.
Note : Marchetti test is same as Bonney’s test, but two Allis forceps are used instead of fingers.
19. Version I
Ans. is d i.e. Tension Free Vaginal Taping (TVT):

19. Version II
Ans. is a i:e Bursch colpo suspension Ref. Telinde 9/e, p 1052-1056
As discussed in preceding text SUI is managed basically by performing either of the two surgeries viz-
1. Burch colposuspension
2. Tension free vaginal tapes/tension free obturator tapes.
The rates of success of these two surgeries are comparable, so if either of them is given in options, we will chose
it.
So in version II- Answer is Burch colposuspension Telinde, 9/e, p 1050-6.
Procedure Long-Term Success Rate (%)
Burch’s colposuspension 89.5
Stamey’s repair 85
Kelly’s repair 50-60
Aldridge Repair 85
Now suppose both Burch colposuspension and TVT is given (Like in version I), then remember-
Tension Free Vaginal Tape (TVT) has emerged as the treatment of choice for genuine stress incontinence in
recent years
Tension Free Vaginal Tape (TVT) is a simple procedure that may be performed under local anesthesia, has a
decreased operative and recovery time, and is as effective as ‘Burch colposuspension’ which was earlier considered
the procedure of choice.
‘A number of surgical procedures have been developed to treat genuine stress incontinence and most aim to
elevate and support the bladder neck. Burch colposuspension was the procedure of choice, but in recent years
this has been superseded by the ‘Tension free Vaginal Tape’ which is showing comparable results and is less
invasive’ Ref. Assessing and managing Acutely III Adult Surgery Patient’ (John Wiley and sonsd) 2007/440
Tension Free Vaginal Tape (TVT)
• Tension Free Vagina Tape (TVT) is a type of suburethral sling that does not have typical ‘suspension sling’ like
mechanism of action.
• TVT involves placement of synthetic polypropylene mesh/tape under the urethra. The sling is placed at the
level of mid-urethra (midurethral sling)
• TVT is a simple procedure that can be performed under local anesthesia, and has the advantage of decreased
operative time and decreased recovery time, while providing a good outcome.
• TVT is believed to be as effective as Burch’s colposuspenstion with cure rates approaching > 80%.
20. Ans. is a, c , d and e i.e. anterior colporrhaphy, colposuspension, pelvic floor excercises and sling operation.
Ref. Shaw 14/e, p 174, Dutta gynae 5/e p387 – 389, Textbook of gynae, shielaBalakrishnan 1/e, p 329 - 330
As explained in preceeding text:
– Pelvic floor exercises – Sling operation
– Colposuspension (Burch) are all done for management of SUI.
As far as anterior colporhaphy is concerned - kellys plication is anterior colporhaphy + Bladder neck repair, so I
have included it in correct option also.
21. Ans. is d i.e. Osteitis pubis

Marshall – Marchetti-Krantz (MMK) procedure, involves the attachment of the periurethral tissue to the symphysis
pubuis. In approximately 3% of patients undergoing the procedure, osteitis pubis develops.
22. Ans. is a, b, and d i.e. Cervical fibroid; Retroverted Gravid uterus; and Severe UTI
Ref. Jeffcoate 7/e, p 855
Important gynaecological causes of acute retention :
Acute retention Other symptoms Diagnosis
Retention + Primary amenorrhea Hematocolposcopy
Retention + Secondary amenorrhea Retroverted gravid uterus
Retention + Menorrhagia Uterine leiomyoma (cervical fibroid)
Retention + No menstrual upset Ovarian or broad ligament tumor
Retention + Irregular bleeding Threatened abortion from a retroverted gravid
uterus or pelvic haematocoele or pelvic abscess
Besides the above causes Jeffcoate 6/e, p 855-858 gives an exhaustive list of other causes of urinary retention- in
which urethritis causing spasm of voluntary external urethral sphincter and acute urinary retention is given.
23. Ans. is c i.e. Impacted cervical fibroid Ref. Read below
The patient in the question :
• Was being treated for infertility.
• Now H/O a 6 weeks of amenorrhea.
• Presents with urinary retention.
The first diagnosis which comes in our mind is Retroverted gravid uterus.
Points which favour the diagnosis are : The woman is pregnant and has complain of urinary retention.
But friends, here it is important to understand that retroverted gravid uterus causes urinary retention at 14 - 15
weeks of gestation (not 6 weeks). ... Jeffcoate 7/e, p 299
So Option “a”. is ruled out
Option “b” Pelvic hematocele
“Pelvic hematocele is formed in a patient complaining of 6 weeks amenorrhea in case of ectopic pregnancy.”
... Jeffcoate 6/e, p 212
Though pelvic hematocele causes urine retention but then other symptoms (pain) and signs of ectopic pregnancy
should be present.
Option “c” Impacted cervical fibroid
“A cervical fibroid impacted in pouch of Douglas can cause retention of urine. The onset of retention is
acute and usually occurs immediately before menstruation, when the uterus is further enlarged by
congestion or during early pregnancy.” ... Jeffcoate 7/e, p 493
Fibroid is associated with infertility.
Thus an impacted cervical fibroid can explain all features seen this woman and is our option of choice.24. Ans. is b, c, d and e i.e. Associated with endometriosis; It is a cause of infertility; Causes menorrhagia;
and Associated with PID Ref. Shaw 15/e pg -345-347; Jeffcoate 7/e, p 295-297
The usual position of the uterus is one of anteversion and anteflexion, in which the body of the uterus is bent
forward at its junction with cervix.
Retroversion is a condition in which axis of cervix is directed upward and backward (instead of forward).

Causes
Developmental Acquired
↓↓↓↓↓ ↓↓↓↓↓ ↓↓↓↓↓• Seen in 20% of patients Mobile retroversion Fixed retroversion
• Retroversion can never be • Prolapse • PID
congenital (it is always developmental) • Puerperium • Pelvic tumors
malformation as the uterus is without • Fibroid • Chocolate cyst of ovary
version and flexion at birth. • Ovarian cyst • Pelvic endometriosis
..... Jeffcoate 7/e, p 295 (pushes uterus backward)
Symptoms :
• Mobile retroversion is usually symptomless, main disadvantage being increased risk of perforation of the uterus
at the time of instrumentation.
Symptoms which can be seen are :
• Spasmodic dysmenorrheaQ
• Pelvic congestion syndrome causing :
– Congestive dysmenorrhea
– Polymenorrhagia
– Premenstrual low backache
– Dyspareunia (it is the most specific and genuine complain in case of retroversion)
– Leucorrhoea
• Infertility : as cervix is directed forward away from the seminal pool and the ejaculation of semen directly into the
external os.
• Abortion : can cause abortion between 10th to 14th week.
Treatment :
• If retroversion is mobile no treatment is required.
• In patient complaining of dyspareunia backache with retroverted uterus : Hodge pessary may be used to keep
uterus in anteverted position.
• Surgical management : – Modified Gilliams operation – Plication of round ligament Q
– Baldy webster operationQ
25. Ans. is c i.e. In a setting of antibiotic treatment Ref. Ananthnarayan 7/e, p 275 - 276
The concept of significant bacteriuria is given by Kass.
Significant bacteriuria refers to bacterial count more than 105/ml of urine
Prerequisite for collection of urine for culture.
• Clean voided mid stream samples of urine are employed for culture. Normal urine is sterile but during voiding
may become contaminated with genital commensals.
• Even under ideal conditions (urine collected by catheterisation), rate of urinary infection is 2%.
• In men, it is sufficient, if mid stream urine is collected after the prepuce is retracted and the glans penis
cleaned with wet cotton.• In women, anogenital toilet is more important and should consist of careful cleaning with soap and water.
Results :
– When bacterial count are more than 105/ml of urine, it is called Significant bacteriuria.
– Counts of 104/ml of urine are due to contamination during voiding and are of no significance.
– In a patient on antibiotic treatment with some bacteria like staph. aureus, even low counts i.e. < 10 5 /ml may be
significant.
