what are other names for enlargement of the prostate?

benign prostatic hyperplasia
what enlargement of the prostate consist?
consists of overgrowth of the epithelium and fibromuscular tissue of the transition zone and periuretheral area
what are known as LUTS?
Lower Urinary Tract Symptoms - symptoms caused by interfering with muscular sphincteric function and by obstruction of urine flow through prostatic urethra
what are some examples of LUTS?
urgency, difficulty in starting urination, diminished stream size and force, increased frequency, incomplete bladder emptying, and nocturia.
what is nocturia
excessive urination during the night
what are the different zones of prostate?

what are the 3 pathologic stages of nodular hyperplasia?
nodule formation
diffuse enlargement of transition zone and periurethral tissue
enlargement of nodules
what is the aetiology of nodular hyperplasia
It is believed that the main component of the “hyperplastic” process is impaired cell death. It has been proposed that there is an overall reduction of the rate of cell death, resulting in the accumulation of senescent cells in the prostate.
In keeping with this androgens (mainly DHT) which are required for the development of BPH, can not only increase cellular proliferation, but also inhibit cell death.
what are some risk factors for prostate carcinoma
> 40 yrs african FH hormone levels environmental influences (increased consumptions of fats)
androgens - important role
what are the treatment for prostatic cancer?
surgery, radiation therapy and hormonal manipulations
radial prostatectomy
external-beam radiation therapy, interstitial radition therapy
what does androgens do in prostate cancer?
maintaining the growth and survival of prostate cancer cells
which genes have a 20-fold increased risk of prostate cancer?
BRCA2
which race has the highest risk?
Northern european and lowest in asian and african descent
what are the aetiology of testicular germ cell tumours?
Prior TGCT in the contralateral testicle
Cryptorchidism
Impaired spermatogenesis
Inguinal hernia
Hydrocele
Disorders of sex development
Prior testicular biopsy
Testicular atrophy
what are the difference between seminoma and teratoma in terms of occurrence period
