Flexible Ureteroscopy Surgery: Procedure, Instruments, Benefits and Recovery
Flexible Ureteroscopy Surgery, also called fURS, is a minimally invasive procedure that helps urologists examine and treat selected conditions of the upper urinary tract. Doctors commonly use flexible ureteroscopy to manage kidney stones and upper ureteral stones.
During flexible ureteroscopy, a surgeon uses a thin, flexible endoscope to reach the urinary tract through the body’s natural passage. Therefore, the procedure usually does not require an external surgical incision.
Furthermore, flexible ureteroscopes provide access to selected areas inside the kidney. When necessary, the surgeon may use compatible laser fibers to fragment stones or retrieval baskets to remove fragments.
However, flexible ureteroscopy is not suitable for every patient. Therefore, doctors assess stone size, location, urinary anatomy, infection status, and overall health before recommending treatment.
JDMeditech supplies urology and endourology instruments for hospitals, healthcare facilities, and medical distributors.
What Is Flexible Ureteroscopy Surgery?
Flexible ureteroscopy is an endoscopic technique that allows urologists to inspect the upper urinary tract using a flexible ureteroscope.
Unlike rigid instruments, flexible ureteroscopes can bend to navigate selected curves within the ureter and kidney collecting system.
As a result, the surgeon can examine areas that may be difficult to reach with a rigid or semi-rigid ureteroscope.
Additionally, the working channel allows compatible instruments to support selected diagnostic and therapeutic tasks.
What Is the Full Form of fURS?
fURS stands for Flexible Ureteroscopy.
Furthermore, flexible ureteroscopy is closely related to Retrograde Intrarenal Surgery, commonly called RIRS.
However, the terms are not completely interchangeable because flexible ureteroscopy can also examine and treat the ureter.
Why Is Flexible Ureteroscopy Performed?
Doctors use flexible ureteroscopy for selected conditions affecting the upper urinary tract.
- Selected kidney stones
- Upper ureteral stones
- Residual urinary stones after previous treatment
- Selected diagnostic evaluation of the renal collecting system
- Assessment of certain upper urinary tract lesions
- Selected endoscopic biopsy procedures
- Selected upper urinary tract abnormalities
However, the clinical indication depends on the patient’s condition and the available treatment options.
What Are Kidney Stones?
Kidney stones are solid deposits that form when certain substances crystallize in urine.
Over time, the crystals may grow and form urinary calculi. Consequently, stones can cause pain, bleeding, or obstruction.
Furthermore, different stone compositions require different prevention strategies.
Common Types of Kidney Stones
- Calcium Oxalate Stones: A common type of kidney stone.
- Calcium Phosphate Stones: May occur with selected metabolic conditions.
- Uric Acid Stones: Often associated with acidic urine.
- Struvite Stones: Commonly linked to certain urinary infections.
- Cystine Stones: Associated with the inherited condition cystinuria.
Therefore, doctors may recommend stone analysis to guide preventive care.
Symptoms of Kidney and Ureteral Stones
Some urinary stones cause no symptoms. However, stones that obstruct urine flow can cause significant discomfort.
- Severe pain in the side or back
- Pain extending toward the lower abdomen or groin
- Blood in the urine
- Nausea or vomiting
- Frequent urination
- Painful urination
- Urinary urgency
- Fever or chills when infection occurs
Important: Fever or chills with suspected urinary obstruction may indicate a medical emergency. Therefore, patients should seek urgent medical care.
When Is Flexible Ureteroscopy Recommended?
Urologists may recommend flexible ureteroscopy when an upper urinary tract condition requires endoscopic evaluation or treatment.
For example, flexible ureteroscopy is commonly considered for selected renal stones below 20 mm.
However, stone size alone does not determine suitability. Therefore, doctors also consider stone density, location, anatomy, and patient preferences.
Flexible Ureteroscopy for Small Kidney Stones
Flexible ureteroscopy can treat selected small kidney stones that require active intervention.
However, observation or another treatment may be suitable for some patients.
Flexible Ureteroscopy for Medium Kidney Stones
Flexible ureteroscopy is a common option for selected medium-sized kidney stones.
Furthermore, compatible laser lithotripsy systems support stone fragmentation.
However, the expected stone clearance depends on the stone burden and anatomy.
Flexible Ureteroscopy for Large Kidney Stones
Surgeons may use flexible ureteroscopy for selected larger stones. However, treatment may require multiple sessions.
Therefore, PCNL is generally preferred for many large or complex kidney stones.
Flexible Ureteroscopy for Lower-Pole Stones
Flexible ureteroscopy may treat selected stones in the lower part of the kidney collecting system.
However, access and stone clearance depend on lower-pole anatomy.
Consequently, the surgeon evaluates imaging before recommending treatment.
Flexible Ureteroscopy for Upper Ureteral Stones
Flexible ureteroscopy can treat selected stones in the upper ureter.
Furthermore, the flexible shaft may help navigate anatomical curves.
However, the surgeon chooses the appropriate endoscope according to clinical requirements.
Types of Flexible Ureteroscopes
Flexible ureteroscopes vary in imaging technology, working channel dimensions, shaft design, and reuse requirements.
1. Digital Flexible Ureteroscope
A digital flexible ureteroscope uses compatible digital imaging technology to provide endoscopic visualization.
Additionally, image quality depends on the selected model and system.
2. Fiberoptic Flexible Ureteroscope
A fiberoptic flexible ureteroscope transmits images through optical fibers.
However, performance and maintenance requirements vary between models.
3. Reusable Flexible Ureteroscope
A reusable flexible ureteroscope supports multiple procedures when the manufacturer permits reuse.
However, healthcare facilities must follow validated cleaning and reprocessing instructions.
4. Single-Use Flexible Ureteroscope
A single-use flexible ureteroscope is intended for one procedure according to its labeling.
Furthermore, disposable models may reduce certain reprocessing requirements.
Flexible Ureteroscopy vs. RIRS Surgery
Flexible ureteroscopy and RIRS use related endoscopic techniques.
However, flexible ureteroscopy describes the use of a flexible ureteroscope, while RIRS specifically focuses on treatment within the kidney collecting system.
Therefore, RIRS often uses flexible ureteroscopy instruments.
Flexible Ureteroscopy vs. Semi-Rigid Ureteroscopy
| Feature | Flexible Ureteroscopy | Semi-Rigid Ureteroscopy |
|---|---|---|
| Instrument Design | Flexible shaft with active deflection | Relatively firm shaft with limited flexibility |
| Common Application | Kidney and selected upper ureteral conditions | Selected ureteral conditions |
| Access to Renal Calyces | Possible in suitable anatomy | Generally limited |
| Imaging | Digital or fiberoptic, depending on model | Depends on model |
| Laser Compatibility | According to device specifications | According to device specifications |
Flexible Ureteroscopy vs. PCNL
PCNL accesses the kidney through a small percutaneous tract.
In contrast, flexible ureteroscopy reaches the kidney through the natural urinary passage.
Therefore, flexible ureteroscopy avoids a percutaneous renal access tract.
However, PCNL is often preferred for larger or complex stone burdens.
Flexible Ureteroscopy vs. ESWL
Extracorporeal Shock Wave Lithotripsy, or ESWL, uses externally generated shock waves to fragment selected urinary stones.
In contrast, flexible ureteroscopy provides direct endoscopic visualization.
Furthermore, compatible laser fibers allow stone fragmentation during selected procedures.
However, each technique has different indications and limitations.
Diagnostic Tests Before Flexible Ureteroscopy
Before surgery, the healthcare team evaluates stone characteristics, urinary anatomy, and patient health.
Ultrasound Examination
Ultrasound may identify urinary stones, hydronephrosis, and other abnormalities.
CT Scan
CT imaging provides detailed information about stone size, location, and urinary anatomy.
Furthermore, it supports treatment planning.
Urine Examination and Culture
Urine testing helps identify infection. Therefore, clinicians review infection status before elective surgery.
Blood Tests
Blood tests may assess kidney function, blood counts, and other relevant factors.
Anesthesia Assessment
The anesthesia team evaluates medical fitness and plans appropriate monitoring.
How Does Flexible Ureteroscopy Surgery Work?
Flexible ureteroscopy uses a thin endoscope to reach selected areas of the upper urinary tract.
During treatment, the surgeon advances a compatible flexible ureteroscope through the natural urinary passage.
Next, the endoscope provides visualization of the ureter and kidney collecting system.
When necessary, compatible laser fibers support stone fragmentation. Additionally, a stone retrieval basket may remove selected fragments.
Finally, the surgeon assesses the operative findings and determines whether temporary urinary drainage is required.
General Steps of Flexible Ureteroscopy
The following overview explains the broad stages of care. However, it does not provide instructions for performing surgery.
Step 1: Preoperative Assessment
First, the urologist reviews imaging, urine tests, kidney function, and medical history.
Step 2: Patient Preparation
Next, the healthcare team prepares the patient according to established surgical and anesthesia protocols.
Step 3: Endoscopic Access
The surgeon establishes suitable access through the natural urinary passage.
Step 4: Flexible Ureteroscope Examination
