When Male Cats in Busan Experience Recurrent Urethral Obstruction and Surgery Needs to Be Considered
"He can't urinate again." If you are a guardian who has made a second emergency room visit due to these words, you are probably standing before the question of 'Do I need to insert another catheter?'
Urethral obstruction is a life-threatening emergency for male cats. Even if it appears to be resolved with a single emergency treatment, if recurrence is repeated, it is difficult to solve the fundamental problem by simply repeating catheter treatment. According to veterinary clinical data from Health Kyunghyang, when urethral obstruction recurs 2-3 times or more, perineal urethrostomy (PU surgery) is recommended as a fundamental solution. Additionally, Health Kyunghyang data points out that repeated catheter insertion can cause urethral mucosal edema and damage, emphasizing that evaluation of surgical transition is necessary at a certain point.
However, the decision regarding surgery is made comprehensively by the veterinarian based on individual conditions such as kidney values, anesthesia risk, and degree of urethral damage. There are no uniform standards applicable to all cats, and the decision must be made only after precise examination and individual consultation.
✓ Key Summary
- Urethral obstruction recurrence 2-3 times or more → PU surgery review is a practical option
- Repeated catheter treatment → cumulative risk of urethral mucosal damage and edema
- Surgical suitability evaluation → comprehensive assessment of kidney values, anesthesia risk, and urethral condition essential
Why Do Male Cats Experience Recurrent Urethral Obstruction — Structural Reasons and Recurrence Risk
The reason urethral obstruction is particularly frequent in male cats begins with anatomical structure. According to PharmaNews, the male cat urethra is longer than in females and becomes increasingly narrow toward the tip of the penis. When calculi, slurry, urethral plugs (agglomerations of mucus and cellular debris), and inflammatory secretions accumulate in this narrow section, obstruction easily occurs due to the structure.
Recurrence rates are also not low. According to Health Kyunghyang data, feline lower urinary tract disease (FLUTD) has clinical reports of recurrence in 39-65% within 1-2 years after treatment. Stress, diet centered on dry food, and chronic lack of water intake are cited as major triggering factors, and if these environmental factors are not resolved, it is difficult to break the recurrence cycle even with repeated catheter placement.
The causes are also diverse. Calculi, idiopathic cystitis, urethral plugs, urethral strictures, etc. — the treatment direction varies depending on the cause, so precise cause investigation must be conducted first in cases of recurrence. A judgment like "it must be the same as last time" can reduce treatment effectiveness.
✓ Major Factors Increasing Recurrence
- Narrow and long urethral structure unique to males
- Diet centered on dry food + chronic water deficiency
- Stress factors such as moving, new family members, environmental changes
- Obesity and reduced activity levels
- Poor environmental improvement without identifying cause after treatment
24H UN Animal Medical Center's Feline Urinary Tract Treatment — From Emergency to Surgery and Post-operative Management
For guardians experiencing recurrent urethral obstruction, what is most desperately needed is a medical environment that does not end with emergency treatment alone.
The 24H UN animal medical center has internal medicine, surgery, and a cat-friendly center collaborating organically, caring for your cat from the day of emergency visit through surgery, hospitalization, and follow-up management within one continuous flow. Located in Daeyeon-dong, Nam-gu, Busan, it has been operating 365 days, 24 hours a day, year-round since its opening in 2016, so emergency veterinarians are on staff even during late night, early morning, and holiday obstruction recurrence, enabling immediate response.
The feline urinary tract treatment flow proceeds as follows.
✓ Emergency Visit — Emergency veterinarian on staff day and night, immediate catheter treatment and oxygen/fluid therapy ✓ Precise Cause Investigation — Blood tests (kidney values, electrolytes), ultrasound, radiography (calculus location and size confirmation) ✓ Internal Medical Stabilization — Intensive inpatient management, kidney function recovery monitoring ✓ Surgical Suitability Evaluation — Pre-anesthesia tests (including heart and kidney function), urethral damage degree evaluation, surgery-dedicated director consultation ✓ Perineal Urethrostomy (PU Surgery) Performance — Post-surgery ICU inpatient management ✓ Post-discharge Follow-up Management — Regular urinalysis, bladder ultrasound, diet and environment management consultation
It operates a cat-friendly center, so the treatment environment for stress-sensitive cats is also separately configured. Treatment results and plans are shared sufficiently with guardians as a basic principle of communication-centered treatment.
Is It Time for Our Child to Consider Surgery Now?
Not every recurrence is an indication for surgery. However, if you are in a situation that corresponds to the following items, surgical correction review should be discussed seriously together by the guardian and veterinarian.
| Confirmation Item | Applicable |
|---|---|
| Urethral obstruction repeated 2 times or more | ☐ |
| Catheter insertion becoming increasingly difficult or impossible | ☐ |
| Physical deformation of the urethra (stricture, scar tissue) confirmed | ☐ |
| Kidney values (BUN, creatinine, SDMA) repeatedly elevated | ☐ |
| Recovery speed after obstruction slower than before | ☐ |
| Recurrence despite stress, diet, and water intake management at home | ☐ |
According to Health Kyunghyang, surgical correction should be actively considered when catheter insertion is impossible or obstruction recurs. This is because repeated catheter treatment can accumulate urethral mucosal edema and damage.
However, individuals with underlying kidney disease or high anesthesia risk due to heart condition must undergo precise pre-anesthesia testing before surgery and have individual consultation with a veterinarian — this is essential. After surgery, as Health Kyunghyang data emphasizes, improved stress environment, adequate water intake, and regular urinalysis are key to recurrence prevention.
In addition to those visiting for feline urinary tract problems in Busan Nam-gu, those looking for cat urethral obstruction in Suyeong-gu or emergency animal hospital for cats in Yeonje-gu can also use the 24H UN animal medical center 365 days, 24 hours a day.
The Next Step Now Needed for Your Child Who Has Been Through Two Emergencies
If signs of urethral obstruction appear even tonight, you can visit the 24H UN animal medical center immediately, and once the condition stabilizes, internal medicine and surgery collaboration will help you determine whether surgery is necessary.
Waiting for a third obstruction can be a very dangerous choice for your cat. According to PharmaNews, if urethral obstruction is not resolved within 48 hours, it can lead to fatal complications such as hyperkalemia, uremia, and acute kidney failure. Each time an emergency situation recurs, the cumulative damage to the kidneys increases.
The completeness of the surgery itself is also important. Health Kyunghyang data emphasizes that the surgical technique level of opening the urethra sufficiently deep and wide greatly determines the prognosis after PU surgery. Therefore, it is important to plan surgery in an environment where surgical experience and internal medicine/surgery collaboration systems are in place.
If your child is currently in a stable condition, undergoing surgical suitability evaluation and precise cause investigation during this period is the most practical preparation for preventing the next emergency. At the 24H UN animal medical center in Daeyeon-dong, Nam-gu, Busan, you can receive consultation and treatment without distinction between weekends and nighttime. After two emergencies, it is now time to look fundamentally at your child's condition.
Essential Information Guardians Must Know After the Second Emergency
Q1. After two emergency treatments, must surgery really be done?
Not necessarily. The decision regarding surgery is made by the veterinarian comprehensively considering not only obstruction frequency but also catheter insertion possibility, urethral condition, kidney value trends, anesthesia risk, etc. However, if recurrence has occurred 2 or more times, it is strongly recommended that you discuss the limitations of repeated catheter treatment and the possibility of surgical transition with the attending veterinarian. The conclusion varies depending on individual condition.
Q2. If perineal urethrostomy (PU surgery) is performed, will urethral obstruction never occur again?
PU surgery removes the narrowest section of the urethra to widen the urinary tract, greatly reducing the risk of mechanical obstruction recurrence. However, cystitis, bladder calculi, and idiopathic lower urinary tract disease can still occur after surgery. Surgery does not guarantee "cure," and subsequent water intake management, stress environment improvement, and regular urinalysis must be maintained.
Q3. What tests are needed before surgery?
To ensure anesthesia safety, blood tests (including kidney, liver, and electrolyte values), thoracic radiography, cardiac ultrasound (cardiac function evaluation), and abdominal ultrasound (bladder and calculus status confirmation) are necessary. If kidney function is impaired, an additional internal medicine stabilization period may be added before surgery, during which the veterinarian will provide individual guidance on surgical timing and risks.
Q4. How should I manage my cat at home after surgery?
After discharge, observe urination frequency and urine color daily, and wet food combination or additional water bowls are recommended to increase water intake. An Elizabethan collar is needed to prevent licking of the surgical site, and stress factors such as moving, new family members, and furniture arrangement changes should be minimized. Do not neglect periodic urinalysis (at 1-3 month intervals) and bladder ultrasound follow-up management.
Q5. What should I do if my cat suddenly cannot urinate at night or in the early morning?
If your cat cannot urinate at all and 4 or more hours have passed, or if your cat repeatedly goes to the litter box but no urine comes out, you should immediately visit an emergency animal hospital. Pressing the abdomen or waiting at home is dangerous. The 24H UN animal medical center has emergency veterinarians on staff 24 hours a day, 365 days a year, enabling immediate response regardless of day, night, or holidays.
