Summary
A rare bladder carcinoid tumor, a type of well-differentiated neuroendocrine tumor, was found in a woman experiencing gross hematuria. Treatment involved transurethral resection and surveillance cystoscopy.
Area of Science:
- Urology
- Oncology
- Pathology
Background:
- Transitional cell carcinoma is the most common bladder cancer in the US.
- Primary bladder carcinoid tumors (well-differentiated neuroendocrine tumors) are exceedingly rare.
Observation:
- This case report details a rare instance of primary bladder carcinoid tumor in a female patient presenting with gross hematuria.
- The tumor's rarity (15-20 reported cases) contributes to an unclear treatment approach.
Findings:
- The patient underwent complete transurethral resection of the bladder carcinoid tumor.
- The recommended follow-up includes surveillance cystoscopy every three months.
Implications:
- This case highlights the importance of considering rare diagnoses in patients with hematuria.
- Further research is needed to establish optimal treatment strategies for primary bladder carcinoid tumors.
- Surveillance protocols may need to be tailored based on tumor characteristics and invasiveness.

3.5K
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...

1.7K
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...

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

01:47Primary Active Transport
199.4K
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

01:06Primary Production
25.3K
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.
