Summary
Transperineal prostate biopsy (TP-Bx) under local anesthesia shows mild, temporary effects on voiding function. Acute urinary retention (AUR) risk is lower than anticipated, supporting TP-Bx as a safe diagnostic option.
Area of Science:
- Urology
- Oncology
- Diagnostic Procedures
Background:
- Transperineal prostate biopsy (TP-Bx) offers reduced infection risk and improved cancer detection.
- Local anesthesia for TP-Bx provides clinical and economic benefits.
- Acute urinary retention (AUR) is a potential post-procedure complication.
Purpose of the Study:
- To assess the impact of TP-Bx under local anesthesia on patient voiding function.
- To evaluate changes in uroflowmetry parameters post-TP-Bx.
Main Methods:
- Prospective observational study of 74 patients undergoing TP-Bx.
- Uroflowmetry assessed pre- and post-procedure, measuring maximum (Qmax) and average (Qave) flow rates, voided volume (Vv), and post-void residual (PVR).
Main Results:
- Significant reductions observed in Qmax and Qave post-TP-Bx (p < 0.001).
- Post-void residual (PVR) increased significantly post-procedure (p < 0.001).
- Observed changes in voiding parameters were mild and did not necessitate catheterization.
Conclusions:
- TP-Bx under local anesthesia demonstrates a lower-than-expected risk of AUR.
- The procedure is a safe and effective diagnostic approach for prostate cancer.
- Experience enhances the safety profile of TP-Bx.

01:13Local Anesthetics: Pharmacokinetics
1.2K
The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...

01:23Local Anesthetics: Mechanism of Action
3.4K
Local anesthetics (LAs) block sensory and motor impulses by inhibiting the sodium channels on the nerve cell membranes. This induces temporary loss of sensation, relieving pain in a specific body area.
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...

01:12Local Anesthetics: Adverse Effects

While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.

01:23Local Anesthetics: Common Agents and Their Applications
985
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
1.5K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

01:30Local Anesthetics: Chemistry and Structure-Activity Relationship
6.7K
Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...
