まとめ
膀胱の神経内endocrine腫瘍（NET）、小細胞がんを含む、はますます認識されている。分子特性評価の進歩により、分類とリスク層別化が向上する。
科学分野:
- 尿生殖器がん;病理学;分子生物学
背景:
- 小細胞がんは、最も一般的な膀胱神経内分泌腫瘍（NET）であり、しばしば他の組織学的型と併存します。膀胱の大細胞神経内分泌がんは認識されていますが、完全には特性評価されていません。分化型NETおよびパラガングリオーマは、まれな膀胱神経内分泌新生物です。
研究 の 目的:
- 膀胱神経内分泌腫瘍の現在の理解をレビューすること。分子特性評価の進歩を強調すること。分類と臨床意思決定への影響を議論すること。
主な方法:
- 膀胱の神経内分泌腫瘍の文献レビュー。最近の分子特性評価研究の分析。分類とリスク層別化に関する現在の知識の統合。
主要な成果:
- 小細胞がんは、支配的なNETサブタイプです。大細胞神経内分泌がんは、さらなる特性評価が必要です。分子の洞察は、腫瘍生物学の理解を向上させています。
結論:
- 分子特性評価の進歩は、膀胱神経内分泌腫瘍の正確な分類とリスク層別化に不可欠です。腫瘍生物学の理解の向上は、まれな膀胱NETの臨床意思決定を支援します。

01:23Urinary Bladder
3.0K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...
