How is undescended testis diagnosed on ultrasound?

See below. Undescended testis is usually diagnosed by physical examination. Ultrasound is used if no testicle can be palpated on either or both sides. Inguinal and abdominal/pelvic us can demonstrate testes in the inguinal canal and most intra-abdominal undescended testes. This helps in management and choice of surgical approach. I perform laparoscopy to find possible intra-abdominal udts if not found by us.
Testicular imaging. Approximately 80% of undescended testes are located within the inguinal canal and are easily visualized with sonography. 20% may be intraabdominal, making evaluation with ultrasound more difficult. Ct imaging may be required in some cases.

Negative result found after ultrasound for undescended testis in scrot, abdomin, inguinal canals means no testis durng birth is it true? Urologst said?

No testes. It is possible to have a child born without testes but a chromosome test should be done to identify sex if it appears the child should be a boy. Read more...
Probably true. True if a tiny lump or nubbin size of a pin head + vas can be palpated in the empty half of scrotum. Laparoscopy is only sure way of ruling out an intra-abdominal testis. Read more...

Potentially serious. If the undescended testis is not corrected. Read more...
Yes. If a testicle is truly undescended (i.e., not just retractile), it can be associated with increased risk of infertility, testicular cancer, and testicular torsion or injury. Those are the indications for repair (orchiopexy). Read more...

Please tell me what the causes could be for undescended testis?

Exact causes unknown. Prematurity, low birth weight, genetic (family history), hormonal (androgen insensitivity), nerve influences, fetal intra-abdominal pressure & prune belly syndrome. Read more...

Undescended testis --- will it descend it without surgery?

Some do some don't. While the testis generally descend & enter the scrotum in late pregnancy, some do not. We will generally watch the process until 6m-1yr before having the infant evaluated for surgery. Each case must be evaluated on its own merits. Read more...
Yes under age-1-year. About 2/3 of undescended testes at birth descend spontaneously. A non-palpable testsi in a full-term baby will never descend on its own and will require surgery. True undescended testes, not to be confused with retractile, normal testes, all need surgery to achieve a normal scrotal position.. Gliding undescended testes can appear to be descended in early childhood and only declare themselves late. Read more...

Can you tell me what the causes could be for a surgery for undescended testis can be?

Minor birth defect. Approximately 1 - 2% of boys have testicular maldescent requiring surgery. 3% of full-term baby boys ; 30% of preemies., most descend spontaneously by age-6-months. Some have udts following hernia surgery. Surgery indicated for non-palpable testes to reduce slight risk of cancer in later life, maximise fertility potential, psychologic to achieve normal appearance ; reduce risk of trauma or torsion.

My husband had b/l undescended testis, he got operated at age 1 and a half years, but only 1 testis could b corrected. Other was removd. Is he fertile?

Yes. He should be. If any question you can obtain a sperm count and a sperm motility study with a doctor's order. Make sure the lab has plenty of experience doing these tests. You don't want a laboratory taking your money that doesn't know what it is doing. Call a urologist office for lab recom. Both the count and the determination of motility are important. They cover both sperm amount and function. Read more...
Possibly. Men with normal testes can be infertile. Men with bilateral undescended testes have high rates of sub fertility. However, you should assume he is fertile and protect yourself from unwanted pregnancy. If trying to conceive, you could obtain a semen analysis for interests sake but the best way to find out is to try! Read more...
Depends on sperm. Semen analysis demonstrate sperm count. Infertility not uncommon with bilaterally undescended testes. We now try to correct as soon after age-6-months as possible to maximize future fertility. Fertility should be OK if count > 20 million/ml. Can still be fertile via artificial insemination, in vitro fertilization (IVF) or intrcytoplasmic sperm injection (ICSI) + IVF if any viable sperm present. Read more...

How many stages r involved in laproscopy for bilat. Nonpalp undescended testis in 6month baby. Whenis it recommended to be completed. Success&complicatio?

You must speak to. the baby's surgeon. Most of the time testis is located at external ring ( near groin ) done with small incision and ixed to the scrotum creating a small pouch. Laparoscopy is not the usual method used. Only the baby's surgeon can answer the outcome issue. Read more...
1 or 2 stages. Depends upon if testes r in inguinal canal or intra-abdominal, if latter, on location of each testis in abdomen & length of spermatic cord. 1 stage if cord long enough, or 2 stage "Fowler-Stephens" operation if cord too short for immediate scrotal placement. Ideally performed at or soon after 6 months if he was full term, later if preemie. 70-90% success. Future fertility may be impaired. Read more...

Hi. I am 25 years old. I was diagnosed with undescended testis at 19. At the time, the doctor decided/advised that I dont get any medication for it. M?

Here are some... Did you see medical professionals for the first time at age 19, that is, 6 years ago? That is very unlikely in the most parts of the world' where have you lived? Though the info is not enough to deduce a reasonable answer, clinically, you may just have retractile testes. Nonetheless, see a urologist for confirmation. How to get it done correctly?

What happen if an undescended testis is not treated until the age 30 years or older?

Won't produce sperm. Testicles undescended at and beyond puberty do not produce sperm. Thus subjects with both testes undescended will be infertile as adults. The undescended testis will also be at increased risk for developing cancer. Undescended testis at age 30 years will still produce testosterone. Suggest you consult a urologist. Read more...
Fibrosis. Depending on the location of the testis, a truly undescended testis left untreated will lose its sperm producing capability. The testis is also at risk for tumors. See your urologist to discuss the merits of surgical treatment. Read more...
