What is purpose of anastomosis between the epididymus and the vas deferens?

What is purpose of anastomosis between the epididymus and the vas deferens?

Fertility: Performed to correct blockage of vas deferens, usually following vasectomy, or epididymal duct. Obstruction to permit passage of sperm. Procedure bypasses obstruction, experts at micro-reconstructive urology believe procure has higher success rate for reanastomosis than vasovasostomy vasectomy reversal. ...Read more

Are the vas deferens are cut and tied in a transurethral resection of the prostate (turp)?

Are the vas deferens are cut and tied in a transurethral resection of the prostate (turp)?

Almost never: Used to be common for some urologists to tie of the vasa deferentia (plural) after open prostate surgery, which was associated with about 2% incidence of epididymitis & when fewer different antibiotics were in existence. Turp is associated with lower incidence of postoperative infection & catheters remain inplace for shorter time compared to open surgery. Thus no need for vasectomy with turp. ...Read more

Coarctation of the aorta . . . Always present from birth?

Coarctation of the aorta . . . Always present from birth?

Yes: By definition coarctation of the aorta is a abnormality of vascular embryology. At birth flow is adequate for the limited activity i the new born and early toddler years, but as children age, their growing bodies and activity out grows the narrowed aorta's ability to supply enough blood fast enough to keep up. ...Read more

Is there any chance of urine reflux into vas deferes or ejaculatory ducts due to prostatitis or urethritis? What are the treatments?

Is there any chance of urine reflux into vas deferes or ejaculatory ducts due to prostatitis or urethritis? What are the treatments?

Epididymitis: This is the proposed mechanism of epididymitis. Usually a strain such as lifting or exercising (increasing intra-abdominal pressure) causes the reflux a very tiny amounts of bacteria laden urine down the vas. The treatment is the same as it is for prostatitis: antibiotics and anti-inflammatories. ...Read more

Does the presence of congenital hernias in children predispose to hernias in adulthood especially since the repair is only a herniotomy but no repair of the posterior wall of the inguinal canal?

Does the presence of congenital hernias in children predispose to hernias in adulthood especially since the repair is only a herniotomy but no repair of the posterior wall of the inguinal canal?

Unknown: As you said there is no repair of the posterior (floor) of the inguinal canal. However they are separate entities with different causes and one should not lead to the other or preclude it. Finally on occasion wih long standing child type hernias can lead to weak floors and this is usually reinforced if discovered at the first operation. ...Read more

Has anybody done surgery to correct a blockage of the vas deferens?

Has anybody done surgery to correct a blockage of the vas deferens?

Yes: Prior vasectomy is a common reason for such surgery with excellent success rates in many patients. Other causes of blocked vas are rare. Epididymal blockage on the other hand is more common from std's and other infections. Surgery to correct this is possible but much lower success rates can be expected. Subspecialty urology would be the best answer for this type problem. ...Read more

Can there be cancer on the vas deferens?

Very uncommon: Cancers of the testicle are much more common than cancers of the vas deferens. While it is possible it is highly unlikely. Cancers of the testicle can involve the vas deferens by direct extension. ...Read more

Does the ilioinguinal and iliohypogastric nerves enters through the processus vaginalis along with vas deferens in the inguinal canal in males?

Does the ilioinguinal and iliohypogastric nerves enters through the processus vaginalis along with vas deferens in the inguinal canal in males?

No: The ilioinguinal nerve is the inferior branch of the iliohypogastric nerve. In the inguinal canal they enter posterior to the processus vaginalis. The pv closes off early in life, so nothing really goes through it. ...Read more

what is the meaning of bilateral patent fallopian tubes?

 what is the meaning of bilateral patent fallopian tubes?

Normal finding.: "Bilateral" = both sides (right & left). "Patent" = open. The "fallopian tubes" are the tubes leading from the uterus to the ovary, i.e. the tube where eggs travel down in order to implant in the womb. Having fallopian tubes open on both sides is a normal finding; unlike a blockage on one side (where the chances of conception go down by at least 50%), both sides being open is considered "normal". ...Read more

Us on testes. What is a focus of increased echogenicity in the right epididymal head presumably on the basic of remote epididymal appendage torsion?

Calcified remnant: With a history of unexplained pain at the capture of your epididymis, it is possible that you had torsion of an appendage (appendix epididymis vs appendix testes) that can become more dense (echogenic) on us. Extremely unlikely to be cancer. ...Read more

Is the size of an undescended testicle abnormal?

Is the size of an undescended testicle abnormal?

Yes: A true undescended testicle is usually smaller than a normal testis for the same age. One school of thought believes that the testis does not descend because it is malformed or maldeveloped and that includes size, ductal connections and length of the spermatic cord. ...Read more
