Final answer:
A biopsy is a procedure in which tissue from the bladder is removed using a needle to obtain a specimen for medical analysis, often to diagnose cancer. The bladder comprises the detrusor muscle and transitional cellular epithelium that allows it to handle changes in volume.
Step-by-step explanation:
Removal of tissue from the bladder by using a needle inserted through the skin overlying the bladder is called a biopsy. This procedure is often done to attain a tissue specimen for analysis in a medical laboratory, frequently to diagnose conditions such as cancer. The bladder is a highly distensible organ that features crisscrossing bands of smooth muscle called the detrusor muscle. The inner surface of the bladder is lined with transitional cellular epithelium that adapts structurally to the organ's volume fluctuations.
During a bladder biopsy, also known as a percutaneous suprapubic biopsy, a needle is guided through the abdominal wall and into the bladder. This method allows the medical professionals to collect samples of tissue from the bladder without the need for an invasive surgical procedure. The collected tissue can then be examined microscopically to assess for abnormalities such as cancerous cells.
