A ureteral stone is a hard mineral deposit that forms in the urinary system and becomes lodged in the ureter, the narrow tube that carries urine from the kidney to the bladder. A stone may begin in the kidney and move downward into the ureter. Once it enters this narrower passage, it can irritate the ureter or partially or completely obstruct the flow of urine.
Ureteral stones are closely related to kidney stones, but their location is different. A kidney stone remains within the kidney, while a ureteral stone has moved into the ureter. This change in location can affect the type and severity of symptoms and may influence the treatment approach.
At Surya Hospital, Puliyangudi, evaluation for ureteral stone problems can help determine the stone's location, size and clinical significance before deciding whether observation, medical management or active stone removal may be appropriate.
The urinary system consists of the kidneys, ureters, bladder and urethra.
The kidneys filter waste and excess fluid from the blood to produce urine. Each kidney connects to the bladder through a ureter. Urine normally travels down the ureter into the bladder and is later released through the urethra.
Because the ureter is relatively narrow, a stone moving from the kidney may become lodged at different points along its pathway. Its exact position can be important when assessing symptoms and deciding on treatment.
A stone located higher in the ureter may produce a different pain pattern from one that has moved closer to the bladder. Therefore, identifying where the stone is located is an important part of ureteral stone evaluation.
Ureteral stones generally develop when minerals and other substances in urine become concentrated and form crystals. These crystals can gradually collect and develop into a stone.
In many cases, the stone initially forms in the kidney. It may then move through the urinary tract and enter the ureter.
Several factors can contribute to stone formation, including inadequate fluid intake, dietary patterns, previous stone formation, certain metabolic conditions and individual tendencies. The exact cause can differ from one person to another.
The composition of the stone also matters. Different types of urinary stones have different chemical characteristics, and understanding the type may be useful when planning prevention after treatment.
Ureteral stones can originate from several types of stone-forming materials.
Calcium-containing stones are among the common types of urinary stones. They can develop when certain minerals become concentrated in the urine and crystallize.
These stones are associated with uric acid in the urine. Dietary and metabolic factors may contribute to their formation.
Struvite stones can develop in association with certain urinary tract infections. They may sometimes grow more rapidly than other stone types and require appropriate medical evaluation.
Cystine stones are less common and are associated with an inherited condition affecting how the body handles certain substances.
Identifying the stone type, when possible, can be useful because preventing another stone may require a different approach depending on its composition and the individual's risk factors.
A single cause does not explain every ureteral stone. A person's hydration, diet, medical history, urinary conditions and previous stone history can all contribute to risk.
Having one or more risk factors does not necessarily mean that a person will develop a ureteral stone. Conversely, stones can occur even when there is no obvious single cause.
Symptoms can vary according to the size, position and movement of the stone, as well as whether it interferes with urine flow.
A common symptom is sudden, intense pain that may begin in the side or back and travel toward the lower abdomen or groin. This type of pain is often referred to as renal colic.
Not everyone experiences the same symptoms. Some stones may produce relatively mild symptoms, while others can cause significant pain.
The ureter contains smooth muscle that helps move urine toward the bladder. When a stone becomes lodged within the ureter, it can irritate the lining and interfere with the normal movement of urine.
The ureter may contract around the stone as the body attempts to move it forward. These contractions, together with irritation and changes in pressure within the urinary system, can contribute to the intense, intermittent pain associated with ureteral stones.
The movement of the stone can also change where the pain is felt. A stone travelling downward may cause discomfort that shifts from the flank toward the abdomen or groin.
Severe pain does not necessarily indicate that surgery will be required. Treatment decisions depend on the complete clinical picture rather than pain intensity alone.
Some ureteral stones can pass naturally without a procedure, particularly smaller stones, but spontaneous passage is not guaranteed. The likelihood depends on factors such as the stone's size, location and the individual's clinical condition.
A doctor may recommend observation for selected patients when there is no indication for urgent intervention and the stone has a reasonable chance of passing. Follow-up may be important to confirm whether the stone has actually passed and whether urine flow remains unobstructed.
A stone that does not pass, continues to cause significant symptoms, obstructs urine flow or is associated with complications may require active treatment.
This is why simply waiting for a stone to pass without appropriate assessment may not be suitable for everyone.
Persistent or significant urinary symptoms should be assessed rather than assumed to be a simple stone problem. Medical evaluation can establish whether the symptoms are caused by a ureteral stone and whether there is any obstruction or other concern.
An obstructed urinary system associated with infection can be a medical emergency and requires urgent professional assessment. The combination of obstruction and infection should not be managed by waiting at home for the stone to pass.
No. Not every ureteral stone requires surgery or a stone-removal procedure.
Depending on the circumstances, a doctor may recommend observation and appropriate medical management when spontaneous passage is reasonably possible and there are no urgent complications.
Active stone removal may become appropriate when a stone is unlikely to pass, causes persistent or recurrent symptoms, produces significant obstruction, contributes to complications, or needs to be removed for other clinical reasons.
The decision should be based on the stone's size and location, symptoms, obstruction, infection risk, kidney function and overall patient factors, rather than on the presence of a stone alone.
Two people with ureteral stones may need different treatment approaches even if their symptoms appear similar.
A smaller stone in one part of the ureter may have a reasonable possibility of passing naturally, while a larger stone or one in a less favourable location may be less likely to pass.
The location also helps the treating doctor understand how the stone is affecting urine flow and which treatment approach may be appropriate if removal becomes necessary.
For this reason, ureteral stone treatment is not based on size alone. Imaging and clinical assessment provide the information needed to make an individualized treatment decision.
Diagnosing a ureteral stone involves more than identifying pain alone. The doctor considers the patient's symptoms, medical history and examination findings and may recommend urine tests, blood tests or imaging to understand the cause and severity of the problem.
Imaging can help determine where the stone is located, how large it is and whether it is affecting the normal flow of urine. Ultrasound may be used as part of the evaluation, while other imaging may be considered when more detailed information is required.
The findings from the assessment help the doctor decide whether the stone can be observed, whether medical management is appropriate or whether active removal should be considered.
There is no single treatment that is suitable for every ureteral stone. The treatment plan is individualized according to several factors, including:
The aim is not simply to remove a stone as quickly as possible. The treating doctor must also consider whether intervention is necessary, which approach is appropriate and what follow-up may be required.
When a ureteral stone is considered likely to pass naturally and there are no indications for urgent intervention, the doctor may recommend observation with appropriate medical management.
During this period, symptoms may be monitored and follow-up may be advised to determine whether the stone has passed. Medication may be prescribed when clinically appropriate to control pain or address other symptoms.
In selected patients with suitable distal ureteral stones, medicines known as alpha-blockers may be considered to facilitate stone passage. Their use depends on the individual situation and should be determined by the treating doctor rather than started without medical advice.
If the stone fails to pass, symptoms continue or complications develop, active stone removal may become necessary.
Active treatment may be recommended when a stone is unlikely to pass naturally or when continuing to wait could create problems.
The decision is made after reviewing the patient's clinical findings and imaging rather than relying on one symptom or measurement alone.
ESWL, or Extracorporeal Shock Wave Lithotripsy, uses externally generated shock waves to break a urinary stone into smaller fragments. These fragments may then pass through the urinary tract.
ESWL is a non-invasive approach because instruments do not need to be inserted directly into the ureter to fragment the stone. However, it is not automatically suitable for every ureteral stone.
After fragmentation, the resulting pieces still need to leave the urinary system. Some patients may require further treatment if significant stone fragments remain.
Therefore, ESWL should be viewed as one possible treatment option, rather than a procedure that is appropriate for every patient.
Ureteroscopy, commonly called URS, is an endoscopic procedure in which a small instrument is passed through the urinary passage to reach and treat a ureteral stone.
Depending on the stone, the surgeon may use an appropriate technique to break it into smaller fragments or remove it. Laser energy may be used for stone fragmentation in suitable cases, followed by removal of fragments when appropriate.
One advantage of ureteroscopy is that the surgeon can directly access the stone rather than relying on externally delivered shock waves.
The suitability of URS depends on the patient's anatomy, stone characteristics, symptoms and overall clinical condition.
Laser technology may be used during ureteroscopic treatment to fragment a stone into smaller pieces. The surgeon can then remove suitable fragments or allow appropriately small fragments to pass.
The exact technique depends on factors such as the stone's size, location and characteristics.
Laser treatment should not be understood as a separate procedure that is automatically required for every patient. It is a tool that may be used as part of endoscopic stone treatment when clinically appropriate.
RIRS, or Retrograde Intrarenal Surgery, is a flexible endoscopic technique primarily used to access the kidney and upper urinary tract.
A flexible instrument is introduced through the natural urinary passage and guided toward the urinary collecting system. A stone can then be treated using appropriate endoscopic and laser techniques.
Because RIRS is particularly associated with access to the kidney's collecting system, it should not be presented as identical to standard ureteroscopy for every ureteral stone.
In some patients with stones involving the upper urinary tract, the treating surgeon may consider RIRS based on the stone's location and other clinical factors.
PCNL, or Percutaneous Nephrolithotomy, is a procedure that provides direct access to the kidney through a small opening in the skin.
It is generally associated with selected larger or more complex kidney stone burdens rather than being the routine approach for an uncomplicated ureteral stone.
For patients who have stones involving both the kidney and urinary tract, the overall stone burden and anatomy may influence the treatment plan. The doctor will determine whether a procedure such as PCNL has a role based on the individual's findings.
This distinction is important because not every ureteral stone requires an extensive kidney stone procedure.
The two approaches treat stones in different ways.
| Feature | ESWL | URS |
|---|---|---|
| Basic approach | Shock waves are delivered from outside the body | An endoscope is used to reach the stone |
| Direct access to stone | No | Yes |
| Stone fragmentation | Uses shock waves | May use laser or another suitable technique |
| Suitability | Depends on stone and patient factors | Depends on stone, anatomy and clinical factors |
| Further treatment | May sometimes be required | Additional treatment may also be required in selected cases |
The choice is not simply about which procedure sounds less invasive. Stone location, size, anatomy and clinical circumstances all contribute to the decision.
The doctor may compare the available options after reviewing imaging and other clinical information.
For example, a stone that is small and likely to pass may be managed differently from a larger stone causing persistent obstruction. Likewise, a stone's location can influence whether ESWL, ureteroscopy or another approach is considered.
This individualized approach helps avoid treating every ureteral stone in exactly the same way.
Preparation depends on the selected procedure and the patient's health.
Patients should provide accurate information about their medicines and medical history. If a procedure requires specific preparation, the hospital team will provide instructions regarding food, fluids, medication and other practical requirements.
The exact process varies according to the selected treatment.
The procedure selected for an individual patient depends on the clinical findings rather than a fixed treatment sequence.
Recovery varies according to the procedure performed, the amount of stone treated and the individual's health.
After active stone treatment, patients may experience temporary urinary discomfort, mild blood in the urine or other symptoms depending on the procedure. The treating team will explain what is expected and what symptoms require medical attention.
Some patients may need follow-up imaging or assessment to determine whether residual stone fragments remain.
A ureteral stent may also be used in selected situations. If one is placed, the patient should follow the doctor's instructions regarding monitoring and its planned removal or management.
Removing or fragmenting the existing stone addresses the immediate problem, but it does not necessarily eliminate the factors that caused stones to form.
For people who repeatedly develop urinary stones, the doctor may also discuss preventive measures based on their history and, when available, the stone's composition.
A consultation is a good opportunity to understand the reasoning behind the recommended treatment. Useful questions include:
Understanding these points can help patients make informed decisions together with their treating doctor.
Recovery after ureteral stone treatment depends on the procedure performed, the stone characteristics and the individual's overall health. Some patients may return to their usual activities relatively quickly, while others may need additional recovery time or follow-up.
Temporary urinary discomfort or mild blood in the urine can occur after certain procedures. The treating team will explain which symptoms are expected and how to manage them.
Patients should follow the discharge instructions provided by the hospital, including advice about medicines, activity, fluids and follow-up appointments. Recovery should be assessed based on the specific procedure rather than a fixed timeline for every patient.
A ureteral stent is a small, flexible tube placed inside the ureter to help maintain urine flow between the kidney and bladder.
A doctor may recommend a stent in selected situations, including after certain stone procedures or when temporary support of urine drainage is clinically necessary.
Having a stent does not necessarily mean that the stone problem is more severe. Its use depends on the procedure performed and the patient's individual circumstances.
Some people may notice urinary frequency, urgency or discomfort while a stent is in place. If a stent has been inserted, patients should follow the doctor's instructions regarding its duration and planned removal or follow-up.
Patients should understand which symptoms require prompt medical attention during recovery.
The appropriate response can depend on the procedure and individual circumstances. When in doubt, contacting the treating medical team is safer than assuming a new symptom is simply part of recovery.
Yes. Removing a ureteral stone does not necessarily prevent another urinary stone from forming in the future.
Stone formation can be influenced by hydration, urine chemistry, dietary factors, medical conditions, family tendency and previous stone history. Therefore, people who have experienced stones may benefit from discussing prevention with their doctor.
Depending on the clinical situation, prevention may involve maintaining appropriate fluid intake, reviewing dietary habits, investigating recurrent stone formation and following recommendations based on the type of stone or identified risk factors.
There is no single prevention plan that is suitable for everyone.
Preventing another stone begins with understanding why stones may have formed in the first place.
If stones repeatedly occur, your doctor may recommend further evaluation to identify contributing factors and develop a more appropriate prevention strategy.
Surya Hospital in Puliyangudi provides evaluation and treatment for patients with ureteral stone problems, with treatment selected according to the individual's clinical findings.
The assessment can focus on understanding the stone's location, size and effect on the urinary tract before deciding on the most appropriate management.
Depending on the clinical indication, stone treatment options available through the hospital include ESWL, URS and RIRS, with the appropriate approach determined according to the patient's condition and stone characteristics.
The objective is to provide a treatment pathway that considers both the immediate stone problem and the patient's need for appropriate follow-up.
People searching for ureteral stone removal in Puliyangudi or ureteral stone treatment in Tenkasi may need different approaches depending on where the stone is located and whether it is causing obstruction or persistent symptoms.
At Surya Hospital, patients can discuss their symptoms and available reports during consultation. The doctor can then assess whether observation is reasonable or whether active stone removal should be considered.
This patient-specific approach is important because a treatment that may be appropriate for one ureteral stone may not be the right choice for another.
Dr. M. Sivasubramanian, M.S., D.MAS., F.MAS., FIAGES, FALS, F.ART , is a General & Laparoscopic Surgeon with 10+ years of experience and serves as the Managing Director of Surya Hospital.
Patients can discuss their ureteral stone concerns, available scan reports and treatment options during consultation. The appropriate treatment plan depends on the patient's individual findings and should be decided after clinical evaluation.
This page does not describe Dr. M. Sivasubramanian as a urologist or attribute credentials beyond the information provided by the hospital.
Bringing relevant information to your appointment can make the consultation more useful.
Tell the doctor if you have experienced fever, difficulty passing urine, repeated vomiting or worsening pain along with your stone symptoms. These details may be important when assessing the urgency of treatment.

A ureteral stone is a urinary stone located within the ureter, the tube connecting the kidney to the bladder. It may have originally formed in the kidney before moving downward. Its size and location can influence symptoms and treatment decisions.
Some smaller ureteral stones can pass naturally. Whether observation is appropriate depends on factors such as stone size, location, symptoms and whether there is obstruction or another complication.
Symptoms may include sudden flank or side pain, pain spreading toward the lower abdomen or groin, painful urination, urinary urgency or frequency, blood in the urine, nausea and vomiting.
Yes. ESWL uses externally generated shock waves to fragment selected urinary stones. Whether it is appropriate depends on the stone's size, location, characteristics and the patient's clinical circumstances.
URS, or ureteroscopy, is an endoscopic procedure used to reach a ureteral stone through the urinary passage. The stone may be fragmented or removed using suitable techniques, including laser fragmentation when appropriate.
No. Both use endoscopic access through the urinary tract, but they have different applications. RIRS uses a flexible scope to access the kidney and upper urinary collecting system, whereas ureteroscopy is commonly used to directly treat stones within the ureter.
No. Selected stones may be monitored when natural passage is reasonably likely and there are no indications for urgent intervention. Active treatment may be considered when a stone persists, causes significant symptoms, obstruction or other complications.
A stone that significantly obstructs urine flow can affect the urinary system and may require medical attention. The potential impact depends on factors such as the degree and duration of obstruction, infection and the condition of the kidneys.
A stent may be placed temporarily to support urine drainage or for other clinical reasons associated with stone treatment. Whether one is needed depends on the procedure and the patient's individual circumstances.
A ureteral stone accompanied by fever or suspected infection, significant obstruction, inability to pass urine, severe worsening symptoms or repeated vomiting requires prompt medical assessment. An infected obstructed urinary system requires urgent treatment.
If you are experiencing symptoms that may be related to a ureteral stone, appropriate evaluation can help determine whether the stone may pass naturally or whether active treatment is required.
