Urinary Tract Calculi VI: Surgical Management

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1. Intravenous Urography (IVU)Intravenous...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
One of the advantages of...

Summary

Paravertebral block (PVB) significantly reduces opioid use and pain scores in patients undergoing percutaneous nephrolithotomy (PCNL). This effective strategy improves pain management after PCNL surgery with no reported complications.

Pain Management

Background:

Postoperative pain management after percutaneous nephrolithotomy (PCNL) for large kidney stones is challenging.
Paravertebral block (PVB) is an effective pain control strategy in various non-urologic surgeries.

Purpose of the Study:

To assess the efficacy of paravertebral blockade (PVB) in managing intraoperative and postoperative opioid requirements.
To evaluate the impact of PVB on postoperative pain control in patients undergoing PCNL.

Main Methods:

Prospective, randomized, double-blind, placebo-controlled trial.
Patients received either PVB or placebo preoperatively, with blinding for patient, surgeon, and anesthesia team.
Outcome measures included intraoperative and postoperative opioid consumption, pain scores (VAS), and antiemetic use.

Main Results:

PVB group showed significantly lower intraoperative and postoperative opioid use and frequency.
Patients receiving PVB reported lower visual analog scale (VAS) pain scores.
No complications were attributed to the PVB procedure.

Conclusions:

Paravertebral block (PVB) is an effective strategy for reducing opioid requirements in PCNL patients.
PVB improves postoperative pain control following percutaneous nephrolithotomy.
PVB should be considered for pain management in PCNL procedures.
