"Clinical study and management of children with imperfect descent of testis".

INTRODUCTION: The testis are specialized paired organs that produces spermatozoa and androgenic hormones. By the 35th to 40th week of gestation they descend into its normal postnatal anatomical location, the scrotum where they function optimally at 33 degree Celsius, a 3-4 degree Celsius less than core body temperature. The testis located in inguinal canal or abdomen is exposed continuously to 35 degree Celsius and 37 degree Celsius respectively with consequent progressive alteration in morphology and physiological functions as well as an increased risk of complications. Since the testis originally develops in the abdominal region, its descent may be inhibited anywhere along its normal pathway or it may be diverted from this route in to an ectopic location. This apparently simple developmental anomaly represents one of the most common disorders of childhood.

It affect all races, and there does not seem to be a geographic propensity, although undescended testis may be associated with a number of chromosomal and hereditary disorders in which specific defect can be identified, at the present time the majority of the cases appear to be isolated. This is probably due to the fact that relatively little is known about what causes the testis to migrate from the abdomen in to the scrotum.

At age 2 years, a testis residing outside the scrotum and in the high temperature zones in the abdomen or inguinal canal would start to deteriorate and this becomes established at age of 5 years.

Early surgical correction helps to avert this and reduce the risk of complication. The undescended testis has greater risk of leading to infertility and tumerogenesis.

Thus it is important to follow mobilization, cord dissection, isolation of patent processes vaginalis and relocation of the testis to the scrotum.

Many terms including cryptorchidism, undescended testis, imperfect descent of testis, maldescent of testis are used. But all terms refer to any testis which is deviated from the normal path of descent from abdomen to scrotum.

We have studied the different locations presented, its associated anomalies and complications and management of imperfect descent of testis.

MATERIAL AND METHODS: children admitted in to the pediatric surgery wardswith the history of absence of testis in the scrotumare included in this study.

This Hospital equipped with the facilities to carry out all necessary investigations to arrive at an accurate pre-operative clinical diagnosis.

Study design: Descriptive study

Sample size: 50

Sample design: Purposive sampling

Study period: Dec 2011 to May 2013

INCUSION CRITERIA: Children of age from day 1 of birth to 18 years who presented with absent testis in scrotum since birth.

EXCLUSION CRITERIA: Children who had intersex disorder and retractile testis. In thisstudy patient's, detailed history was taken, routine investigations like TC, DC, Hb and systemic examination were done in all patients. Ultrasound examination of the abdomen was done in all cases.

All patients were treated surgically after taking proper consent from the patient's parents, open and lap orchidopexy were the surgeries performed.

If the cases are bilateral, patients were advised to undergo surgery later for the other side,every patient was advised for follow upregularly once a month at the time discharge from the hospital.

RESULTS:

1. AGE INCIDENCE

The average age of presentation in the study is 6 years.

2. SIDE OF INVOLVEMENT

Right side is the most common side of involvement i.e 21 cases,

3. Symptoms

The commonest symptom in all cases was absence of testis in the scrotum. Groin swelling was present in 8 cases (16%). Pain in the swelling was also present in 3(06%).

4. Palpable Testis

Most common site where testis was found is superficial pouch 12(29.26%) followed by inguinal region 11(26.82%).

5. Ectopic testis

6. Impalpable Testis

Most common site of impalpable testis was canalicular 5(62.5%) followed by intra-abdominal 2(25%).

7. Location of improper descent of testis

Most common site found was in superficial pouch.

8. Anomalies associated

8.1. Anomalies associated with imperfect descend of testis with respect to age

Most abnormalities found were of gubernaculums

8.2 Anomalies associated with imperfect descent of testis with respect to location of the testis

Most common abnormality was of gubernaculum in mid-scrotal region

9. Surgery:

1. Ultrasound of abdomen was done in 50 cases. In 5 cases testis was present in the root of scrotum, 6 patients external ring, 12 patients in the superficial pouch, 11 patients inguinal canal, 8 cases are intra-abdominal (in 8 intra-abdominal cases) one case testis was present in the lumbar region, in one case it was present in right iliac fossa. One case in the pelvis and 5 are canalicular absent testis in 1 case.

2. Blood and urine examination was done routinely in all the cases for preoperative assessment of the patient.

3. Screening chest was also done in all the patients. Other relevant investigations were also done.

We did 41 cases of open orchidopexy and 8 cases of lap orchidopexy and for 1 absent testis in abdomen, only diagnostic lap was done.

Post-operative period: Was uneventful.

FOLLOW UP: we only followed up for any ascent of testis after orchidopexy, any atrophy of testis, and wound infection. But due to lack of time in our study, we were not able to study regarding fertility of patients

ASSOCIATED SYNDROMES: We got 2 cases of beck with- Weidman syndrome

ASSOCIATED COMPLICATIONS: 2 cases with obstructed hernia

DISCUSSION:

1. PRESENTING AGE GROUP:

In the present study of 50 patients

* 7 patients were below 2 years of age (14%).

* 28 patients were between 2 to 5 years of age (56%).

* 11 Patients were between 5 to 10 years of age (33.34%).

* 4 patients were between 10 to 18 years of age (36.67%).

This series is compared with M.B. Jackson et al series in which 60 boys were included in the study, as shown in below.

The present series has shown that the majority of the patients were detected in 2-5 yrs age group, compared to Jackson et al series. Few of the patients were detected in the school health check up and were referred to our hospital.

2. SIDE OF INVOLVEMENT

Right is the most common side of involvement in our study.

3. FAMILY HISTORY

4 patients had family history of imperfect descent of testis in our study.

4. TYPES OF UNDESCENDED TESTIS

Kaplan(1993) proposed the most popular system, which categorizes imperfect descent of testes as either palpable or impalpable.

The subject nature of the physical examination confounds the accurate classification of testicular position. A more accurate assessment occurs at the time of surgery.

PALPABLE TESTIS

We have got less cases in upper scrotum compared to Hutson& Baker studies (57a, 57b)

IMPALPABLE TESTIS

(Found intra operatively)

5. ASSOCIATED ABNORMALITY

6. ASSOCIATION OF NEOPLASIA WITH UNDESCENDED TESTIS

7. FERTILITY AND UNDESCENDED TESTIS

Orchidopexy was done before reproductive age group in many of our patients. Long term follow-up could not be done because of lack of time in the study period.

We didn't do orchidectomy for any cases.

CONCLUSION: Undescended testis is most common in right side.In palpable Undescended testis, superficial pouch is the most common site where the testis is found. In ectopic, femoral is the most common site. In impalpable testis most common is canalicular.

Open orchidopexy for palpable and lap orchidopexy for impalpable testis is most common operation performed.

Many of the undescended testis descend within one year of age, hence we should wait till one year of age.

Orchidopexy for undescended testis should be done within 2 years of age as histopathological changes start around 2 years of age till 16 years where irreversible histopathological changes takes place.

Routine pre-operative imaging for undescended testis is neither necessary nor helpful. Ultrasound or MRI do not accurately localizes a true non palpable testis and hence does not alter the surgical management. Laparoscopy directly should be used for evaluation of children with impalpable undescended testis.

SUMMURY: Imperfect descent of testis is the most common problem encountered in pediatric surgery OPD. Many theories have been proposed for imperfect descent of testis, but till today the exact etiology still unknown.

In this descriptive study 50 children of age from day 1 of birth to 18 years, who presented with the complaints of absent testis were selected on the basis of purposive sampling.

This study was conducted between Dec 2011 to May 2013, all of the 50 children fulfilling the inclusion and exclusion criteria after detailed examination underwent abdominal and scrotal scanning. And for palpable testis open orchidopexy was done and for impalpable testis lap orchidopexy was done.

In our study:

* 56% incidence is present in 2-5 years of age.

* 42% of undescended testis were present on right side

* 82% cases are palpable in undescended testis

* In palpable testis 30% cases are present in superficial pouch followed by inguinal canal(26%)

* In impalpable testis 77% of cases present in canalicular region followed by intra abdominal(22%).

* 2 children who presented with impalpable testis were found to have of Beck-with weidmann syndrome.

* We got 2 cases presented with obstructed inguinal hernia and on examination were found to have undescended testis

* We did 41 cases of open orchidopexy and 8 cases of lap orchidopexy and for 1 absent in abdomen, only diagnostic laparoscopy was done.

* Orchidopexy carries 98% of success rate

* Follow up was done for any ascent, atrophy of testis and wound infection.

* We did not get any complications, but due to lack of time in our study we were not able to study regarding the fertility of the patient.
