A study of mullerian duct anomaly on reproductive age group.

INTRODUCTION: The mullerian ducts are the primordial anlage of the female reproductive tract; hence a wide variety of malformations can occur when this system is disrupted. They range from uterine and vaginal agenesis to duplication of the uterus and vagina to minor uterine cavity abnormalities. Mullerian abnormalities are frequently associated with abnormalities of renal and axial skeletal systems; mullerian abnormalities are often first encountered when patients are examined for those associated conditions. (Anomalies of Vertibras & Ribs; a Developmental Field Defect).

Most mullerian duct abnormalities (MDAs) are associated with functioning ovaries and age appropriate external genitalia. These abnormalities are often recognized after the onset of puberty.

In the prepubertal period, normal external genitalia and age appropriate developmental milestones often mask abnormalities of the internal reproductive organs. After the onset of puberty, young women often present to the gynaecologists with menstrual disorder; late presentations include infertility and obstetric complications & also psychiatric problem. (1)

The aim of the study of different cases of gynaecological and obstetrical problems of reproductive age group associated with developmental anomalies of reproductive organ by different diagnostic method (Hysterosalpingography (HSG), ultrasonography (USG), hysteroscopy, laparoscopy and biochemical test where feasible) & to throw light on the frequency of their presence in normal population & also follow up of such cases after application of corrective measure, if at all correctable.

MATERIALS AND METHODS: The study was performed at G.O.P.D. & infertility clinic of a regional medical college hospital of West BENGAL with prior permission of authority.

Subjects of this study were selected from Department of Obstetrics and Gynaecology (Both from inpatients and outpatient department) and infertility clinic who came with complaints of primary amenorrhoea, primary infertility, post caesarean recurrent breech, pain abdomen, urinary retention, habitual abortion, primi with transverse lie, etc. The age limit of the subjects was taken from 12 years to 50 years.

The most basic classification of Mullerian duct defect consists of agenesis & hypoplasia, defect of vertical fusion & lateral fusion. In 1979, Buttram & Gibbons. (2) proposed a classification of MDA that was based on the degree of failure of normal development, & they separated these anomalies into classes that demonstrate similar clinical presentations, treatment & prognosis. (3) for fetal salvage. Modified in 1988 by a sub-committee of American Fertility Society the most widely accepted classification.

                 complete agenesis or     involve the vagina, cervix,
                      hypoplasia             fundus, tubes, or any
                                             combination of these
                                          (MRKH) syndrome is the most
                                            common example in this

II                Unicornuate uterus      When an associated horn is
                  with or without a         present, this class is
                   rudimentary horn      subdivided into communicating
                                           (Continuity with the main
                                        uterine cavity is evident) and
                                             noncommunicating (No
                                           continuity with the main
                                             uterine cavity). The
                                           noncommunicating type is
                                           further subdivided on the
                                              basis of whether an
                                         endometrial cavity is present
                                        in the rudimentary horn. These
                                         malformations have previously
                                             been classified under
                                           asymmetric lateral fusion
                                             defects. The clinical
                                             significance of this
                                          classification is that they
                                         are invariably accompanied by
                                         ipsilateral renal and ureter
                                           agenesis (Buttram2, 1979;

STATISTICS: The author uses the following formulas (5) for calculation of study results.

1. Standard deviation is "Root-Means-Square-Deviation" denoted by the Greek letter sigma c or standard deviation.

Standard Deviation =

When [summation] [(x [bar.- x]).sup.2] square of summation
of duration of Each value form arithmetic mean [(x [bar.- x]).sup.2].
n- Is the sample size.
If sample size <30; n is replaced by ([eta] - 1)

2. Standard Error of the Mean:

S.E. [bar.x]=S/[square root of ([eta])]
= S stands for standard deviation of mean
[eta] [right arrow] stands for total no. of sample.

3. P value:

3. P value - P = [[summation] x-[x.sup.1]/[summation]x] x 100

[summation]x [right arrow] Total no. of sample provides treatment.
[X.sup.1] [right arrow] Person with good outcome.

If P. value is < 0.05 [right arrow] Significant at 5 percent level.

If P. value is = 0.05 [right arrow] just significant at 5 percent level.

If P. value > 0.05 [right arrow] not significant at 5 percent level.

A test of significance will measure the probability of result by mean. If the probability of occurrence of such a difference is less than 5 times out of 100, it is said to be significant or statistically significant, i.e., P < 0.05. In that case, the difference will be due to the treatment modalities in more than 95% of such experiments. The sample estimate is then said to be significant or significantly different at 5% level of significance. This difference could be by chance only once in twenty trials. The difference is highly significant if the probability of chance occurrence is less than 1%. (P < 0.01).

RESULTS: The Study has been performed at outpatient dept. of Gynae & Obst., Regional. M.C.H., WB with collaboration of radiology department (for radiological investigations) and (pathology department for diagnosis of sex chromatin). Patients were selected randomly from GOPD and emergency OT. From June 2006 to Aug-2007. 54 patients with various problems of mullerian duct anomaly asked for treatment.

The analysis of clinical data, etiology and the result of outcome are given below:

It shows maximum patients clusters at the peripubertal age; patients mainly with Gynaecological problem come during this age group while patients with Obstetrical problem come at the most fertile period (21-30 yrs).Standard Deviation from this table of age distribution is 15.9.

It shows that maximum patients asking for treatment is of Hindu category. Standard Deviation from this table of Caste distribution is 16.6.

Standard Deviation from this table on the basis of Gross problem is 16.6.

It shows maximum patients come without any menstrual problem but with other problems (primary infertility; recurrent abortion; retention of urine; dyspaurenia; incidental findings etc.) followed by primary amenorrhoea.

Standard Deviation from this table on the basis of menstrual problem is 6.6 which show standard error with the range of approx. 3.8.

It signifies maximum patients with vaginal atresia are associated with Rockitansky-KauserHauser syndrome.

Standard Deviation from this table on the basis of problem of vaginal atresia is 3.1. Which shows standard error with the range of approx. 1.55.

Standard Deviation from this table on the basis of obstetrical problem is 1.7. Which shows standard error with the range of approx. 0.98.

It can be concluded that majority of patient with mullerian abnormality have bicornuate uterus.

Standard Deviation from this table on the basis of Mullerian duct abnormalities is 9.7.

So, whether these congenital anomalies have association with consanguineous marriage cannot be ascertained.

So it can be concluded that majority of patients whether coming with gynaecological or obstetrical problems were satisfied with the treatment. i.e., out of 54 patients, 38 have surgical/medical measurement (2 awaiting, 30 good result, 3 fair, 2 tubal ligation, 1 poor), 5 awaiting, 2 defaulter, 9 others (DES, Diagnosed male, waiting for delayed puberty).

On the basis of outcome the above table depict the p value which is test of significance of the result is 0.03. (So, p<0.05).

It shows Ultrasonography is accurate upto 96.3% to detect the congenital anomaly.

Prevalence of congenital anomaly at G.O.P.D. of R. G. K. M.C.H is 0.15 which is very near to value given in literature (0.16%;). (6)

Standard Error of estimation of prevalence is 6.25%.

DISCUSSION: The aim of the study was to search out the different congenital anomalies of female reproductive organ and to improve the qualities of life of those patients with different new treatment modalities. While performing the study for last fourteen months the author faced several problems owing to the poor economic status of the patients and socio cultural condition.

In fact, there was amalgamation of experiences with which the study reached to a point to refresh our previous experience about the incidence of these cases (May not be true reflection of actual prevalence or incidence); it also gave an idea about how to tackle those poor soul who are suffering from such structural, morphological, sexual and above all psychological ailments.

Malformations of uterus may not be stamped as rare as it is probable that many malformations are never diagnosed because many patients with such malformations are able to conceive and proceed to term without complication. (7)

In certain malformations surgical intervention is justified such as patient having habitual abortion, preterm delivery with no living issue and pent up menstrual discharge with/without infection due to failure of canalization. (8)

Mullerian duct anomalies encompass a wide spectrum of clinical and imaging findings, and while many of the anomalies will be diagnosed initially at HSG or two-dimensional US, further imaging with MR and, potentially, three-dimensional US will often be required for a definitive diagnosis.

Magnetic Resonance imaging (MRI) currently is the study of choice because of its high accuracy and detailed elaboration of uterovaginal and ovarian anatomy. Laparoscopy and hysteroscopy are then reserved for women, in whom interventional therapy is being undertaken, thus reducing health care expenditures and sparing women from invasive diagnostic procedures.

Ultrasonography imaging should be performed during the secretory phase of the menstrual cycle, when the endometrial thickness and echo complex are better characterized. US has a reported pooled accuracy of approximately 90%-92% Endovaginal US has advantage of improved spatial resolution, although at the expense of a decreased field of view.

Hysterosonography, with infusion of saline into the endometrial canal, provides improved delineation of the endometrium and internal uterine morphology;

Hysterosalphinogogram (HSG) is indicated in the early stages of evaluation of the infertile couple. The examination provides a morphologic assessment of the endometrial and the endocervical canals and supplies important information regarding tubal patency. Characterization of uterine anomalies can be difficult; notably with regard to differentiation of a septate from a bicornuate uterus. And the inability to evaluate the external uterine contour adequately HSG also entail exposure to ionizing radiation in these typically young women.

Three Dimensional Ultrasonography with surface and transparent mode reconstruction of the uterus has reported advantageous over conventional two dimensional scanning. In experienced hand, a sensitivity of 93% and specificity of 100% have been achieved.

Magnetic Resonance Imaging Technique has a reported accuracy up to 100% in the evaluation of mullerian duct anomalies. Although MRI is more expensive than US, its great accuracy makes it more trusted by many gynaecologist. MRI provides clean delineation of internal and external uterine conture. MRI depicts utero vaginal morphology, thus aiding in classification of anomalies.

The primary goals of surgical intervention (9) are to relieve obstruction and pain, to restore a normal sex life, and to preserve the patient's reproductive potential. The timing of surgery depends on the patient's anatomic configuration and on the presence or absence of functional endometrial tissue. In the patient with functional ovarian tissue but an absent uterus and vagina, reconstruction of the genital tract is not medically urgent. (10)

Variations in patients' anatomic findings and the lack of a standardized surgical technique complicate the outcomes and prognosis. One of the major limitations encountered in this study was the inability to make an etiological diagnosis for all patients. The author feels the imperative need of future research programme in order to find out the appropriate cause for these sets of patients. In every case one should always be careful about the psychological aspect of the patient; keeping this in mind it may be wiser not to explain the true fact to the patient.
