Post-Procedure Review and Prevention of Feline Ureteral Stenting: A Visit to Dongtan Iyum Animal Hospital

To put it briefly, the core message of this article is that a cat’s ureteral stenting procedure is not a sudden emergency but a condition that can be sufficiently prevented through long-term environmental enrichment and proper hydration management.

This article details the accurate surgical process, recovery management, and most importantly, recurrence prevention strategies based on the experience of ureteral stones and stenting procedures at Dongtan Iyum Animal Hospital, providing essential information for pet owners.

While many cat guardians feel fear upon hearing the word ‘stones’, actual veterinary diagnoses and surgical procedures are very precise and systematic. In particular, Dongtan Iyum Animal Hospital is highly sensitive to managing cats’ stress, focusing on minimizing anxiety during procedures. Through this article, I will explain, based on concrete data, the causes of pain cats experience, dietary management during recovery, and how behavioral enrichment using PlayCat wooden toys contributes to stone prevention.

If you read this article to the end, you will be able to prepare in advance for emergency situations caused by ureteral stones and gain practical knowledge to extend your cat’s quality of life. Beyond a simple hospital visit report, I hope this article will be a great help in preparing prevention management strategies based on feline physiology.

Why is Feline Ureteral Stenting Necessary? How is the Pre-Surgical Diagnosis Process Conducted?

Causes of Ureteral Stones and Feline Physiological Vulnerabilities

The fundamental reason why cats suffer from ureteral stones is not just the habit of drinking little water, but because cats’ own metabolism and urine production mechanisms are completely different from dogs and other animals. Cats excrete urine in a highly concentrated state compared to other mammals, which is an evolutionary result of the body trying to conserve water efficiently. However, due to this physiological characteristic, minerals such as calcium, magnesium, and phosphorus in the urine easily precipitate to form crystals.

In particular, recent studies report that the incidence of stones in indoor cats is more than twice as high as in outdoor cats. This is because indoor cats have fewer opportunities to naturally drink water and reduced movement, leading to decreased urine volume. Analyzing various cases diagnosed at Dongtan Iyum Animal Hospital reveals that the disease occurs most frequently during the adult stage (1-7 years old). Especially in male cats, due to the narrow structural characteristics of the urethra, cases where stones block the urethra are frequent. In other words, even small stone clumps are classified as a high-risk group capable of blocking the ureter and causing acute ureteral obstruction.

Additionally, stress in cats promotes hormone secretion, changing the acidity of the urine and accelerating stone formation. If guardians keep cats confined or fail to help them adapt to new environments, cortisol levels rise sharply. This impairs kidney function and creates a chemical environment that facilitates stone formation. Therefore, it is very important to understand what stress factors the cat is currently exposed to and how that environment affects the body before considering surgery.

Ultrasound Diagnosis and Blood Tests: The Process of Accurately Assessing the Condition

The first step taken at Dongtan Iyum Animal Hospital to accurately assess a cat’s ureteral status is non-invasive ultrasound imaging. This is a critical process to visually confirm the location, size, quantity of stones, and the degree of ureteral dilation before surgery. Through the ultrasound equipment, the veterinarian can observe in detail where the stone is located in the ureter and whether inflammation or infection is accompanying the tissue around the stone.

For example, if a stone is located at the lower part of the ureter (where it connects to the bladder) and is blocking it, this is judged as an urgent emergency situation. On the other hand, if the stone remains inside the bladder or is located near the kidney, the treatment strategy changes. In addition to ultrasound, a blood test (Biochemistry profile) is conducted as a necessity, which is crucial for checking kidney function levels (Creatinine, BUN) and electrolyte balance.

Especially, blood test results are very important to check for symptoms of kidney failure caused by ureteral obstruction. If a cat fails to excrete urine properly for a long time, waste products accumulate in the bloodstream, potentially causing severe kidney failure, which is a life-threatening condition. Dongtan Iyum Animal Hospital evaluates the cat’s overall physical condition based on these figures. If kidney function is severely impaired, the process of protecting kidney function and restoring electrolyte balance through intravenous fluid therapy (IV fluid therapy) must be undertaken before proceeding with surgery.

Additionally, urine analysis (Urinalysis) is performed to analyze the composition of the stones. Most feline stones consist primarily of Struvite components, which are formed in an acidic urine environment with high magnesium/phosphorus concentrations. However, Calcium Oxalate stones also exist, and this component does not dissolve even in a slightly acidic environment, posing a high risk of recurrence even after surgical removal. Therefore, accurate analysis of the stone’s composition provides essential information for establishing future dietary treatment and prevention strategies.

Pre-Surgical Stress Management and Behavioral Approach

Cats can be considered closer to solitary mammals than social animals, and they have a very high fear of veterinarians and hospital environments (Veterinary Fear). At Dongtan Iyum Animal Hospital, the cat’s condition is carefully managed from before the surgery, considering these psychological factors. This goes beyond simple emotional consideration; it is an essential procedure based on feline physiology.

Sedatives or anesthesia induction processes used by veterinarians to keep cats in a restrained state play a decisive role in lowering stress levels. In a state of high stress, heart rate rises sharply, blood pressure increases, and the immune system is suppressed, increasing the risk of complications during surgery. Therefore, at Dongtan Iyum Animal Hospital, before taking the cat to the Examination Room, we prioritize methods such as spending a short time with the guardian in a quiet space or using Feliway pheromone spray to provide a sense of security in the environment.

[Note: Always consult with a veterinarian]

Additionally, the fasting period before surgery is also handled importantly. Cats may have intestinal contents remaining in the body and not moving from the small intestine to the large intestine within 4 hours after eating. If vomiting occurs during anesthesia for stone surgery, there is a risk of aspiration pneumonia where that content enters the airway and damages the lungs. Therefore, food and water must be withheld 12 hours before surgery. While this may be somewhat painful for the cat, it is an essential safety device to save their life.

Feline Ureteral Stenting Procedure and Recovery Period Management

Purpose and Surgical Method of Ureteral Stenting

Ureteral Stenting is a treatment that expands the ureter to open blocked parts while maintaining the ureteral passage until the stone is removed or excreted. The main purpose of this procedure is to resolve ureteral obstruction to prevent kidney damage and immediately solve the painful difficulty of urination for the cat. The stenting procedure performed at Dongtan Iyum Animal Hospital mostly uses an endoscope, which is a minimally invasive surgical method that allows precise surgery without making large incisions in the cat’s abdomen.

The surgical process is divided into three main stages: anesthesia induction, stone removal or stent insertion under ultrasound guidance, and recovery. First, the cat receives general anesthesia, and the ureter is exposed while the excretory muscles are relaxed. At this time, the veterinarian inserts a very sophisticated endoscope into the ureteral opening to observe the internal structure. The part blocked by the stone is removed, or if the stone is too large to be naturally excreted, it is crushed.

Next, even if there are traces of removed stones, a stent is inserted to prevent the narrow part of the ureter from being blocked again. The stent is a fine tube made of metal or plastic that supports the ureteral wall to temporarily secure the passage. This stent is usually maintained for a few weeks to a few months, after which it is removed according to the veterinarian’s instructions, or it is designed to decompose itself in the case of absorbable stents. This process leaves only a small incision in the cat’s abdomen and is characterized by a fast recovery rate.

The reason Dongtan Iyum Animal Hospital chooses this surgery is to provide the cat with the fastest recovery with minimal trauma and pain. Additionally, after stent insertion, guardians are advised on thorough food management and hydration induction strategies to prevent stones from accumulating again. This is not just a simple surgery; it must include a long-term management plan to lead to successful treatment.

Diet and Hydration Management During the Recovery Period After Stenting

The recovery period after ureteral stenting is the most important stage in determining the success of the surgery. Immediately after surgery, symptoms such as vomiting or dizziness may occur as the cat wakes up from anesthesia, requiring the guardian’s attention. At Dongtan Iyum Animal Hospital, we check if urine is being excreted properly within 24 hours after surgery and observe if the urine volume is increasing normally. If urine does not come out or blood-mixed urine is continuously excreted, this is a sign that the stent may be blocked or new stones are forming, so you must contact the hospital immediately.

In terms of dietary management, the most important thing is the rapid introduction of ‘Wet Food’. Immediately after surgery, start with a mild diet that is easy for the cat to digest, but gradually transition to wet food with high water content. Wet food has a water content of over 70%, providing more than 10 times the water compared to dry kibble. This is a key factor in reducing kidney burden and preventing stone reformation.

Guardians should be careful that if wet food is given immediately after surgery, the cat may show a rejection reaction. Therefore, it is recommended to start by mixing a small amount of water with the usual food to make a paste, or gradually increase the amount of wet food using a transition method. Additionally, the location of the water bowl should be moved to a place the cat likes, or water should be placed in multiple locations to improve accessibility.

It is ideal to use prescription diet (Prescription Diet) in consultation with a veterinarian. Especially, brands like Urinary S/O or C/D diets are formulated to regulate urine pH levels and reduce magnesium and phosphorus content, which are causes of stone formation. Dongtan Iyum Animal Hospital recommends suitable prescription diets based on the cat’s stone composition analysis results, which should be consumed long-term for prevention management.

Importance of Pain Management and Antibiotic Administration

Pain management after surgery is essential for controlling the cat’s recovery speed and stress level. Cats have a strong habit of hiding pain even when they are in pain, so guardians should not judge that there is no pain just because the cat is active. At Dongtan Iyum Animal Hospital, we prescribe non-steroidal anti-inflammatory drugs (NSAIDs) for about 3 to 5 days after surgery to relieve pain. This drug plays a role in reducing pain and inflammation while protecting kidney function.

Additionally, antibiotics are administered to prevent infection at the surgical site. Since ureteral endoscopy involves the ureter, an internal organ connected to the outside, there is a risk of bacterial infection. Antibiotics are usually taken for about 7 to 14 days, and this must be strictly followed according to the veterinarian’s instructions. If antibiotics are stopped midway, resistant bacteria may develop, making the problem worse. Therefore, it is important to take the medication for the prescribed period even if symptoms disappear.

Due to pain, cats often try not to move or lose their appetite. In such cases, it is good for guardians to actively show interest in the cat, provide gentle massage, or place familiar items nearby to give a sense of security. Additionally, maintaining the cat’s litter box area clean and washing it daily in case of urine odor is also important as part of pain management.

Connection Between Stone Recurrence Prevention and Behavioral Enrichment

Main Causes of Stone Recurrence: Insufficient Water Intake and Stress

Even if the ureter is temporarily opened by ureteral stenting, the risk of stone recurrence still exists. Statistically, stone recurrence cases are reported in more than 30% of cats, mostly due to insufficient management after surgery or continuous environmental factors. The biggest cause is still insufficient water intake. Cats have evolved to conserve water instinctively, and if guardians do not induce water intake while living indoors, the number of times they drink water naturally decreases.

Most guardians consulted at Dongtan Iyum Animal Hospital answer, “The cat didn’t drink water, so stones formed.” However, simply adding more water does not solve the problem. Cats are very sensitive to the shape, location, and surrounding environment of the water bowl when drinking. For example, if water is placed in a wide bowl, cats may avoid it touching their mouths (preferring flat-bottomed bowls), or if water is placed next to the litter box, they may avoid drinking due to the smell of urine.

Another major cause is stress. As mentioned earlier, stress raises cortisol levels, changes the acidity of the urine, and promotes stone formation. Changes in the guardian’s lifestyle, moving, the appearance of a new animal, or aggressive attitudes from other animals can cause stress in cats. If these stress factors are not continuously managed, the stone problem solved by surgery may return.

Prevention Strategy Through Behavioral Enrichment

The most effective and fundamental method to prevent stone recurrence is ‘behavioral enrichment’, which stimulates the cat’s natural instincts. This aims to make the environment more interesting and challenging for the cat, increasing activity levels and reducing stress. Dongtan Iyum Animal Hospital recommends behavioral enrichment as part of the post-surgery management plan, which directly affects increased urine volume along with improved physical fitness.

The first element of behavioral enrichment is ‘play’. Cats feel happiness only if their hunting instincts are satisfied. If the guardian invests at least 2 times a day, for more than 10 minutes, in逗引 play, the cat feels natural thirst through energy consumption. Increased activity levels lead to more active metabolism, and consequently, increased water intake, which greatly helps prevent stone formation.

The second element is ‘environmental composition’. Wooden toys or structures like PlayCat provide spaces for cats to hide, climb, and observe. When an environment is created where the cat can move on its own, the cat can move sufficiently even beyond the time the guardian plays with it. Especially, utilizing vertical space is very important for cats, playing a major role in relieving stress and providing a sense of security.

Additionally, changing the feeding method is also part of behavioral enrichment. Instead of feeding once a day, divide the food into small portions multiple times, or change to using a puzzle feeder so the cat has to use its head to get the food. This extends mealtime and naturally increases water intake. This is a very effective lifestyle correction method for preventing stone recurrence.

Feline Ureteral Stenting Cost Comparison and Preventive Economics

Surgical Cost vs. Prevention Cost: Economic Analysis from a Long-Term Perspective

It is true that many guardians find the cost of feline ureteral stone surgery burdensome. The cost of Dongtan Iyum Animal Hospital’s endoscopic ureteral stenting procedure is usually between 500,000 and 800,000 won, which is a significant burden on a typical household budget. However, it is important to view this not just as ‘surgical cost’ but in comparison to ‘prevention cost’ from a long-term perspective.

Treatment costs for complications caused by stones can be much higher than surgical costs. For example, if stones recur even after surgery and require repeated surgeries, additional surgical and anesthesia costs occur. Furthermore, if it leads to severe kidney failure requiring long-term treatment or kidney transplantation as a last resort, the cost can reach millions of won, which is a problem that must consider not only the cat but also the guardian’s mental and physical burden.

Therefore, when comparing surgical costs to prevention costs, we reach the conclusion that investing in ‘recurrence prevention and management’ rather than ‘one surgery’ is more rational. The cost of wet food for prevention (around 5,000-10,000 won per day) and PlayCat toy costs for behavioral enrichment (purchased once for long-term use) are very low amounts compared to surgical costs. In other words, investing a little more time and dispersing costs in prevention management before investing in surgical costs becomes a strategy that ultimately saves more money.

Paradox of Product Selection and Rational Selection Guide

There are many various diets and supplements for stone prevention in the market, but guardians have many products to choose from. This creates confusion by experiencing the ‘paradox of choice’. However, at Dongtan Iyum Animal Hospital, we emphasize that because suitable products differ depending on the cat’s stone composition (Struvite or Calcium Oxalate), products should be selected based on accurate diagnosis rather than blindly choosing famous products.

For example, since Struvite component stones are formed in an acidic urine environment, an alkaline diet that neutralizes this should be selected. On the other hand, Calcium Oxalate components do not dissolve even in an alkaline environment, so simply adjusting pH is difficult to solve, and continuous management is required even after surgery. Therefore, guardians should trust the veterinarian’s prescription diet recommendation and choose the product that best suits the cat among that brand’s products.

Additionally, a similar problem occurs when selecting toys for behavioral enrichment. It is better to choose 2-3 products that match the cat’s personality rather than getting caught up in price or design and purchasing complex products. For example, while puzzle feeders are effective for active cats, hidden structures may be more effective for shy cats. PlayCat’s wooden furniture is most suitable for stimulating cats’ natural behaviors (climbing, hiding, observing) to reduce stress, which provides indirect but powerful help in stone prevention.

Advanced Information: Additional Tips Useful for Both Beginners and Experienced Owners

Stone Occurrence Risk and Management Strategies by Age

A cat’s age is an important variable in stone occurrence risk and management strategies. Kittens (0-1 year old) may develop stones due to nutritional imbalance during growth and rapid growth. Especially when weaning and rapidly switching to high-protein food, kidney burden may increase. Therefore, during the kitten stage, it is important to choose food with balanced nutrients rather than growth food and ensure adequate water intake.

Adult cats (1-7 years old) are active but are a period where water intake may be insufficient due to indoor living. This is the period with the highest incidence of stones, so prevention management must be focused. Especially, adult cats deepen their relationship with guardians, so reducing stress through behavioral enrichment greatly helps in stone prevention.

Senior cats (7 years and older) are a period where kidney function begins to decline. Cats at this stage have reduced urine concentration ability, are prone to stones, and have a high risk of existing stones growing. For senior cats, intake of wet food and prescription diets that induce water intake is essential, and it is recommended to visit a veterinary nephrology specialist hospital for regular blood tests and urine analysis.

Differences in Stone Management Based on Cat Personality

A cat’s personality greatly affects stone management strategies. Cats with an active personality have high activity levels and relatively high water intake, but they may become dehydrated due to excessive exercise. Therefore, these cats need to ensure sufficient rest time and create an environment where they can drink enough water after exercise.

On the other hand, cats with shy or aggressive personalities are very vulnerable to stress. Since stress promotes stone formation, stress management through behavioral enrichment is the key to stone prevention for these cats. Guardians should read the cat’s signals well, maintain a stable environment, and manage stress using sedatives if necessary.

FAQ: Specific Questions and Answers That Readers Actually Search For

Q1. Is feline ureteral stenting painful? How should it be managed?

The surgery itself is performed under anesthesia, so the cat does not feel pain during the procedure. However, pain and dizziness may occur as the cat wakes up from anesthesia after surgery. Dongtan Iyum Animal Hospital prescribes non-steroidal anti-inflammatory drugs for about 3-5 days after surgery to relieve pain. Guardians should carefully observe if the cat tries not to move or loses its appetite, and it is important to administer the prescribed medication accurately. Additionally, providing gentle massage and a stable environment to reduce stress also helps in pain management.

Q2. Can stones form again after ureteral stenting? What is the recurrence rate?

Ureteral stenting is a treatment for temporary passage securing, and the risk of stone recurrence still exists. Statistically, stone recurrence cases are reported in more than 30% of cats, mostly due to insufficient management after surgery (water intake, diet control, stress management) or continuous environmental factors. Therefore, do not rest assured just because it is solved by surgery; consult with a veterinarian and thoroughly manage prevention. Especially, monitoring water intake and stress reduction through behavioral enrichment is essential for preventing recurrence.

Q3. How much is the cost of feline ureteral stone surgery, and does insurance apply?

The cost of Dongtan Iyum Animal Hospital’s endoscopic ureteral stenting procedure is usually between 500,000 and 800,000 won. This includes anesthesia, surgical fees, hospital fees, and medication costs during the post-surgery recovery period. Insurance applicability varies depending on the pet insurance company you have joined, and most cover only a portion of surgical costs, while prevention management costs (food, toys, etc.) are not covered. Therefore, investing in prevention management can be a strategy that ultimately saves more money.

Q4. What methods are effective for making cats drink more water?

Cats have evolved to conserve water instinctively, and if guardians do not induce water intake while living indoors, the number of times they drink water naturally decreases. An effective method is the rapid introduction of wet food (Wet Food). Wet food has a water content of over 70%, providing more than 10 times the water compared to dry kibble. Additionally, the location of the water bowl should be moved to a place the cat likes, or water should be placed in multiple locations to improve accessibility. It is recommended for guardians to feed wet food that induces water intake and change the water 2-3 times a day.

Q5. Can using PlayCat toys help prevent stones?

Wooden toys like PlayCat greatly help reduce stress by stimulating cats’ natural behaviors (climbing, hiding, observing). Since stress raises cortisol levels, changes the acidity of the urine, and promotes stone formation, stress reduction through behavioral enrichment provides indirect but powerful help in stone prevention. Additionally, increased activity levels through toys lead to more active metabolism, and consequently, increased water intake, which greatly helps prevent stone formation.

Conclusion

Feline ureteral stones are not just a simple disease but an important indicator showing how the guardian’s management and environment affect the cat’s health. Through the surgical experience and prevention management strategies at Dongtan Iyum Animal Hospital, we can learn that saving a cat’s life starts not just from medical intervention but from daily lifestyle habits and environmental creation.

Remember that surgery is a last resort and prevention is the most important treatment. Increasing water intake, reducing stress, and satisfying the cat’s natural instincts through behavioral enrichment are the key to preventing stone recurrence. We hope this article helps guardians protect their cats’ health.
