Kidney and Ureteral Stone Treatment in Türkiye: ESWL, Ureteroscopy, RIRS, Laser and PCNL Guide

Quick answer: does every kidney stone need surgery?

No. Some small, uncomplicated stones with a reasonable chance of passing can be managed with pain control, an individual fluid plan, medicines selected by a clinician and follow-up imaging. However, an obstructed kidney with infection, impaired kidney function, obstruction of a solitary functioning kidney, uncontrolled pain or persistent vomiting may need urgent treatment.

Treatment should not be chosen from stone diameter alone. Location in the kidney or ureter, density, urinary anatomy, previous procedures, blood-thinning medicines, possible pregnancy, body habitus, infection and patient priorities should all be considered. Claims such as “the best laser for everyone” or “guaranteed stone-free in one session” deserve caution.

Which symptoms require urgent assessment?

Flank pain with fever, shaking chills, marked weakness or confusion may indicate an infected obstructed kidney. Inability to pass urine, suspected obstruction of a solitary kidney, worsening uncontrolled pain, persistent vomiting, fainting, heavy bleeding or severe pain during pregnancy also warrant local urgent assessment.

When infection and obstruction occur together, the immediate priority is usually to drain the kidney with a ureteral stent or nephrostomy and control the infection—not to complete definitive stone fragmentation at once. Stone removal is generally planned at a safer later stage. This situation should not be delayed for planned medical travel.

What is the difference between a kidney stone and a ureteral stone?

A stone in the kidney may remain asymptomatic. When it enters the ureter, it can block urine flow and cause waves of severe flank pain, pain radiating to the groin, nausea, urinary frequency or blood in the urine. Blood in the urine is not caused only by stones; infection, kidney disease and urinary-tract tumours may also need exclusion.

The decision is based not simply on the presence of a stone but on obstruction, pain, infection and the effect on the kidney. A small asymptomatic renal stone and a similar-sized stone completely blocking the ureter may be managed very differently.

Which tests may be used for diagnosis?

Assessment usually starts with symptom onset, previous stones, family history, diet, fluid intake, medicines and other medical conditions. Depending on the clinical situation, tests may include:

• Urinalysis and urine culture when infection is suspected

• Blood tests for kidney function, blood count and selected metabolic factors

• Low-dose non-contrast CT to identify size, location, obstruction and anatomy

• Ultrasound for children, pregnancy or situations in which radiation should be limited

• A plain urinary-tract X-ray for selected follow-up

• Laboratory analysis of a passed or removed stone

• A twenty-four-hour urine collection and metabolic assessment for recurrent or higher-risk stone disease

Patients are advised to keep the original DICOM images as well as the report. Stone density, skin-to-stone distance and lower-pole anatomy can affect the likely result of ESWL; a report that only states “stone present” may not be enough for treatment planning.

Which factors guide treatment selection?

The urologist may consider:

• Stone diameter, number, total burden and density

• Location in the kidney, upper, middle or lower ureter, or bladder

• Whether urine flow is obstructed

• Pain, infection, bleeding and kidney function

• Urinary-tract narrowing, renal anatomy and previous surgery

• Pregnancy, obesity, bleeding risk and suitability for anaesthesia

• Anticoagulants and other medicines affecting infection or bleeding risk

• Travel timing, tolerance of a stent and access to follow-up

• The surgeon's experience with the proposed procedure and the hospital's emergency support

A newer technology is not automatically more suitable. The aim is acceptable stone clearance with the lowest reasonable risk, preservation of kidney function and a follow-up plan that can be completed.

When may observation and medical expulsive therapy be considered?

Some small ureteral stones may pass when there is no infection, kidney-function threat or uncontrolled pain. A clinician may recommend pain relief, treatment for nausea and, for selected patients, medicine that can facilitate ureteral stone passage. Advice to drink large volumes needs individualisation in people with kidney or heart disease.

Observation is not unmonitored waiting. Pain, urine output, signs of infection and stone movement should be reviewed. A stone that does not pass within the agreed period, causes persistent obstruction or seriously affects daily life may require reconsideration of intervention.

How does ESWL work?

Extracorporeal shock-wave lithotripsy focuses shock waves from outside the body to fragment the stone. The pieces then pass in the urine. Avoiding a skin incision can be an advantage, but results vary and more than one session may be needed.

Stone size, position, hardness, skin-to-stone distance and free urinary drainage influence the outcome. Very hard stones, difficult lower-pole anatomy, pregnancy, uncontrolled infection or unacceptable bleeding risk may make another approach more appropriate.

Possible effects include pain, blood in the urine, bruising, blockage by fragments and the need for another procedure. A stent before ESWL is not required for every patient; stone burden and the risk of obstruction should guide that choice.

What are ureteroscopy, RIRS and laser lithotripsy?

During ureteroscopy, a thin endoscope passes through the urethra and bladder into the ureter without a skin incision. Rigid or semi-rigid instruments are often used for ureteral stones. Flexible ureteroscopy, also called retrograde intrarenal surgery or RIRS, can reach cavities within the kidney.

The stone may be extracted directly or fragmented with a holmium or thulium-fibre laser. Some pieces are removed in a basket while small fragments may be left to pass. “Dusting” does not mean every fragment disappears; follow-up imaging may still be required.

Risks include infection or sepsis, ureteral injury, bleeding, stone migration, residual fragments, later narrowing and repeat treatment. A large stone burden may require staged RIRS. Urine culture and infection control are central to safe planning.

Why might a ureteral stent be inserted?

A JJ stent is a temporary thin tube that keeps urine flowing from the kidney to the bladder. It may be used when there is swelling or ureteral injury, residual fragments, infection risk or concern about obstruction. It is not mandatory after every uncomplicated ureteroscopy.

A stent may cause urinary frequency, urgency, blood in the urine, bladder discomfort or flank pain. Its removal date, method and responsible clinic should be stated in writing. A forgotten stent can become encrusted, infected and difficult to remove. Before returning to Europe, confirm whether removal will occur in Türkiye or in the country of residence.

When may PCNL or mini-PCNL be considered?

Percutaneous nephrolithotomy creates a small tract through the back into the kidney so that stones can be fragmented and removed. It may be considered for large, multiple, branching or otherwise complex renal stones. Mini-PCNL uses a smaller tract, but the word “mini” does not eliminate the risks of bleeding, infection or injury to nearby structures.

The procedure is commonly performed under general anaesthesia. A nephrostomy tube, ureteral stent or both may be left temporarily. Bleeding, transfusion, fever or sepsis, adjacent-organ injury, urine leakage, residual stone and further procedures should be discussed. Hospital observation and flight planning may be more substantial than after ureteroscopy.

Emergency drainage: stent or nephrostomy?

An infected obstructed kidney can be drained in two principal ways. A ureteral stent is placed internally between kidney and bladder. A percutaneous nephrostomy drains urine through a tube inserted through the back into an external bag. Choice depends on clinical condition, anatomy, anaesthetic risk, stone location and local expertise.

Drainage helps control the source of infection but is not definitive stone removal. Antibiotics are adjusted to culture findings and clinical response, and stone treatment is planned after stabilisation.

A concise comparison of the options

ESWL

It is incision-free and may offer a less invasive first approach for suitable stones. Fragment passage can take time, and repeat treatment, colic or another intervention may be required.

Ureteroscopy or RIRS

These procedures reach the stone directly through the natural urinary tract. Laser and baskets can be used. Anaesthesia, infection risk, a temporary stent and sometimes a second session remain possible.

PCNL or mini-PCNL

This approach may offer greater clearance potential for a large or complex renal stone burden. Because a tract enters the kidney through the skin, bleeding, infection and inpatient observation can be more prominent considerations.

The preferred procedure should not be selected before reviewing the images and excluding or treating infection. Staged or combined methods may be recommended in selected cases.

Questions to ask before treatment

• What are the exact location, size, density and degree of obstruction?

• Is the urine culture clear, and is an antibiotic genuinely needed?

• Why is this method recommended, and what are the reasonable alternatives?

• What is the expected chance of needing a second session?

• Will a stent or nephrostomy be used, and who will remove it and when?

• How will residual fragments be assessed?

• How should anticoagulants and other regular medicines be managed?

• Is there access to intensive care, blood products and emergency urology if required?

• Which records and follow-up are needed after returning to Europe?

Anticoagulants and regular medicines should not be stopped without a clinical plan. If urinary infection is suspected, culture and clinical assessment may be safer than repeated empirical antibiotics arranged only by message.

Planning treatment in Türkiye and follow-up in Europe

Before travel, share CT images and reports, urine culture, kidney-function results, any previous stone analysis, operation notes and a complete medicine list. A remote preliminary plan may change after examination and updated testing in Türkiye.

Discharge does not automatically mean fit to fly. Pain, fever, urinary flow, bleeding, a stent or nephrostomy, mobility and clot risk should be reviewed together. Written procedure-specific flight advice and a check of airline requirements are recommended.

Take home the operation and discharge summaries, DICOM images, culture results, stone analysis, prescriptions, stent or nephrostomy details, the removal plan and warning signs. Clinicly's urology treatments in Türkiye guide gives the wider clinical context, while the follow-up after returning to Europe guide focuses on care transfer.

How can the risk of another stone be reduced?

Removing a stone does not necessarily end the stone-forming condition. Analysis of a passed or removed fragment can guide individual prevention. A fuller metabolic assessment may be advised for recurrent stones, stones on both sides, early onset, a solitary kidney, a strong family history, bowel disease or a less common stone type.

General prevention may include enough fluid to maintain dilute urine, reducing excessive salt, eating a balanced diet, keeping normal dietary calcium and avoiding excessive animal protein. Fluid targets must be individualised in heart or kidney failure. Arbitrarily restricting calcium can be counterproductive for some stone formers.

Calcium oxalate, uric-acid, infection and cystine stones do not have the same dietary or medical prevention. Potassium citrate, a thiazide, allopurinol or other medicines should be prescribed only after reviewing stone, blood and urine findings. A universal online “stone-dissolving remedy” is not safe or effective for every stone.

What should a cost comparison include?

Ask whether the written quotation includes:

• Urologist, anaesthesia, theatre and hospital admission

• CT, ultrasound, blood tests, urinalysis and culture

• Number of ESWL sessions or laser and disposable endoscopy equipment

• Stent, nephrostomy, guidewires, baskets and other consumables

• Stent removal and follow-up imaging

• Stone analysis and metabolic assessment

• Extra nights, blood products, intensive care and complication management

• A second session or change to another procedure

• Interpreting, transfers, accommodation and companion expenses

• Follow-up and device removal costs in Europe

With an unusually low package price, check whether stent removal, disposable equipment, repeat treatment or complication care has been excluded. Clinicly's article on the potential risks of very cheap treatment offers can support this comparison.

How can Clinicly help?

Clinicly can support the secure transfer of CT images and medical records to urology teams experienced in stone surgery, comparison of written preliminary plans and organisation of questions about method, stent, follow-up, travel and cost. Language support, appointments, transport and post-treatment communication may also be coordinated.

Clinicly does not diagnose, prescribe antibiotics, provide emergency care or guarantee a stone-free result. Final diagnosis, procedure selection, antibiotic use, stent or nephrostomy decisions and fitness to fly remain the responsibility of licensed healthcare professionals.

Frequently asked questions

Can a kidney stone pass without a procedure?

Some small, uncomplicated ureteral stones can pass. The likelihood depends on size and location, while infection, obstruction and kidney function require monitoring.

Does laser dissolve every kidney stone?

No. A laser fragments a stone under endoscopic vision. Large or complex stones may require another session, leave residual fragments or be better treated by another method.

Is ESWL better than RIRS?

There is no universal answer. Position, density, size, anatomy, bleeding risk and patient priorities determine which option may be preferable.

Is an antibiotic enough when a stone is present?

In an infected obstructed system, antibiotics alone may be insufficient and urgent drainage may be required. Local emergency assessment should not be delayed.

Is a stent required after every ureteroscopy?

No. It may be omitted after some uncomplicated procedures. Ureteral injury, swelling, residual fragments, infection or obstruction risk influence the decision.

Can a patient return to Europe with a stent?

Sometimes, but symptom control, infection and blockage warnings, medicines, removal date, responsible clinic and flight clearance should be documented.

Is PCNL open surgery?

No. It is a percutaneous procedure using a small tract through the back. It is nevertheless a significant intervention with bleeding, infection and hospital-monitoring considerations.

How is stone-free status checked?

Ultrasound, X-ray or low-dose CT may be used according to stone type and procedure. The urologist should define the timing and modality.

Is drinking more water enough to prevent recurrence?

Adequate fluid is important for many people, but stone-specific diet, salt reduction, treatment of metabolic conditions or medicine may also be needed. Fluid targets require personalisation in some heart and kidney conditions.

Which documents should the patient take home?

Obtain operation and discharge notes, DICOM images, culture and blood results, stone analysis, prescriptions, stent or nephrostomy details, removal arrangements and follow-up instructions.

Conclusion

The key question in kidney and ureteral stone treatment is not “Which is the newest laser?” but “Which plan is safest and sustainable for this stone's location, composition and risks?” Observation, ESWL, ureteroscopy, RIRS and PCNL each have value for different patients and stone patterns. People considering care in Türkiye are advised to assess infection safety, the surgeon's stone expertise, the stent-removal plan, European follow-up and recurrence prevention as carefully as the price. Clinicly can help organise options and record transfer; personal treatment decisions should follow specialist assessment.
