Introduction:

Medical procedures involving the urinary tract can often cause discomfort or pain. To reduce this, healthcare providers rely on local anaesthetics that work quickly and effectively. One widely used product is Urojet, a pre-filled syringe containing lidocaine gel. It is designed to provide both anaesthesia and lubrication during diagnostic and therapeutic procedures.

This article explores everything you need to know about Urojet, including what it is, how it works, its advantages, risks, precautions, and commonly asked questions.

What Is Urojet

Urojet is a sterile, single-use syringe pre-filled with lidocaine hydrochloride gel. Lidocaine is a local anaesthetic that temporarily numbs mucous membranes, making procedures less painful. The gel form of Urojet also acts as a lubricant, reducing friction during the insertion of medical instruments.

Urojet is most commonly used in urology, but it also has applications in gynecology and other specialities where short-term mucosal anesthesia is required.

Composition of Urojet

Urojet primarily contains:

• Lidocaine hydrochloride – the active anesthetic ingredient
  
• Sterile water: the base for the gel
  
• Stabilizers and preservatives – to maintain effectiveness
  

The gel usually contains 2% to 4% lidocaine concentration and is available in pre-measured volumes, which allows precise dosing without additional preparation.

How Urojet Works

Urojet numbs the area by blocking sodium channels in nerve cells, which prevents the transmission of pain signals to the brain. Because it is a gel, it also coats and lubricates the passage, easing the insertion of instruments such as catheters or scopes.

This dual action of anaesthetic relief and lubrication makes Urojet particularly useful in clinical practice.

Medical Applications of Urojet

Urology

• Catheterisation: Urojet is applied to reduce pain during urinary catheter insertion.
  
• Cystoscopy: Used before inserting a cystoscope to examine the bladder and urethra.
  
• Urodynamic testing: Helps improve patient comfort during diagnostic bladder function tests.
  
• Urethral dilation: Numbs and lubricates the urethra when widening is required.
  

Gynecology

• Assists in minor vaginal or cervical procedures requiring local anesthesia.
  

Other Applications

• Endoscopic interventions where mucosal anesthesia is needed
  
• Minor surgical procedures involving sensitive mucous membranes
  

Benefits of Urojet

Urojet provides several advantages that make it a preferred option for many healthcare providers.

• Pain reduction: Effectively numbs the area, improving patient comfort.
  
• Lubrication: Reduces friction during instrument insertion.
  
• Sterile and single-use: Lowers the risk of contamination and infection.
  
• Pre-filled convenience: Saves preparation time for medical staff.
  
• Patient cooperation: Less pain means less anxiety and smoother procedures.
  

Step-by-Step Application

Only trained professionals should administer Urojet, but here is a general overview of how it is applied:

1. The syringe is inspected for integrity and expiration date.
   
2. The patient is positioned comfortably for the procedure.
   
3. The syringe tip is gently inserted into the urethra or target passage.
   
4. The gel is slowly instilled into the area.
   
5. A short waiting period of about 5 to 10 minutes allows the anaesthetic to take full effect.
   
6. The intended medical procedure is performed once numbness is achieved.

Possible Side Effects

Most patients tolerate Urojet well, but some may experience side effects.

• Temporary irritation or stinging at the site of application
  
• Mild numbness beyond the target area
  
• Rare allergic reactions to lidocaine
  
• Headache, dizziness, or drowsiness in sensitive individuals
  
• Extremely rare cases of lidocaine toxicity if excessive amounts are used
  

Precautions and Contraindications

Healthcare providers take several factors into account before using Urojet.

• Allergies: Patients allergic to lidocaine or similar anaesthetics should not use it.
  
• Liver conditions: Since lidocaine is processed in the liver, caution is needed in patients with liver disease.
  
• Heart disorders: People with certain heart rhythm issues should be carefully monitored.
  
• Pregnancy and breastfeeding: Should only be used under medical supervision.
  
• Drug interactions: Urojet may interact with other medications such as antiarrhythmics.

Urojet Compared to Other Lidocaine Options

Why Urojet Is Preferred in Urology

Doctors often choose Urojet because it simplifies the process while keeping patients comfortable. Its dual action reduces procedure time, prevents unnecessary trauma, and helps patients remain relaxed. Since it comes in sterile packaging, it also aligns with infection control standards in hospitals and clinics.

Storage and Handling

Urojet must be stored properly to maintain its effectiveness:

• Keep at room temperature.
  
• Protect from direct sunlight.
  
• Do not freeze.
  
• Check packaging for damage or expiration before use.
  
• Always discard after single use.

Patient Experience

Patients who undergo procedures with Urojet generally report less pain and discomfort. Patients often describe the cooling gel sensation as relieving, although they may feel a brief sting at first. They usually cooperate better when healthcare providers use Urojet, which helps medical staff perform procedures more smoothly.

Frequently Asked Questions

What is Urojet used for?
Doctors use Urojet to numb and lubricate the urethra or mucous membranes during medical procedures.

How quickly does Urojet work?
It usually starts working within 5 to 10 minutes.

Is Urojet safe?
Yes, but it should only be administered by a healthcare professional.

Can it be used at home?
No, Urojet is for clinical use under medical supervision.
