Transition zone (TZ) 5% The transition zone surrounds the proximal urethra. [2] ~10–20% of prostate cancers originate in this zone. It is the region of the prostate gland that grows throughout life and causes the disease of benign prostatic enlargement. [6] [7] Anterior fibro-muscular zone (or stroma) —
Benign prostatic hyperplasia (BPH), also called prostate enlargement, is a noncancerous increase in size of the prostate gland. [1] Symptoms may include frequent urination , trouble starting to urinate, weak stream, inability to urinate , or loss of bladder control . [ 1 ]
In HGPIN, the basal cell layer is disrupted but present. PIN is primarily found in the peripheral zone of the prostate (75-80%), rarely in the transition zone (10-15%) and very rarely in the central zone (5%), a distribution that parallels the zonal distribution for prostate carcinoma. [7]
Transition zone (Earth), a part of the Earth’s mantle located between the lower mantle and the upper mantle; Transition zone, the region between the near and far fields of a transmitting antenna; Transition zone (TZ), a glandular region of the prostate—see Prostate#Zones; Zone of transition, a zone in urban planning; Ciliary transition zone ...
The prostatic urethra, the widest and most dilatable part of the urethra canal, is about 3 cm long.. It runs almost vertically through the prostate from its base to its apex, lying nearer its anterior than its posterior surface; the form of the canal is spindle-shaped, being wider in the middle than at either extremity, and narrowest below, where it joins the membranous portion.
Transitional cell carcinoma is a type of cancer that arises from the transitional epithelium, a tissue lining the inner surface of these hollow organs. [1] It typically occurs in the urothelium of the urinary system ; in that case, it is also called urothelial carcinoma .
The scope is passed through the urethra to the prostate where surrounding prostate tissue can then be excised. There are two types of modalities: There are two types of modalities: Monopolar TURP: A monopolar device utilizing a wire loop with electric current flowing in one direction (thus monopolar) can be used to excise tissue via the ...
