Summary
This summary is machine-generated.Medical expulsive therapy (MET) using tamsulosin helped a dog with ureteral stones pass the obstruction. This non-surgical approach resolved severe kidney injury and azotemia, offering a potential treatment for canine ureterolithiasis.
Area Of Science
- Veterinary Medicine
- Nephrology
- Pharmacology
Background
- Ureterolithiasis, or ureteral stones, commonly causes ureteral obstruction and kidney injury in dogs.
- Medical expulsive therapy (MET) with alpha-adrenergic antagonists aims to reduce ureteral smooth muscle tone, facilitating stone passage.
- Nonsurgical management is desirable for selected cases of canine ureterolithiasis.
Purpose Of The Study
- To evaluate the efficacy of tamsulosin as part of medical expulsive therapy (MET) for ureteral obstruction in a dog.
- To assess the resolution of azotemia and ureteral obstruction following MET in a canine patient.
Main Methods
- A 9-year-old Chihuahua with anorexia presented with severe azotemia and confirmed ureteral obstruction due to ureteroliths.
- Medical expulsive therapy (MET) with tamsulosin was initiated after surgical intervention was declined.
- Close clinical monitoring, including serum biochemistry and ultrasonography, was performed.
Main Results
- The dog showed improvement in azotemia and resolution of ureteral obstruction after 3 days of MET.
- Ultrasonography confirmed dilation of the renal pelvis and ureteral distention prior to treatment.
- Markedly elevated kidney biomarkers (SDMA, BUN, creatinine) normalized with treatment.
Conclusions
- Tamsulosin, as part of MET, shows potential as a non-surgical treatment for obstructive ureterolithiasis in dogs.
- This case highlights the successful management of ureteral obstruction and associated kidney injury using MET.
- Further investigation into tamsulosin's role in canine ureterolithiasis is warranted.

Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...
Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...
Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...
Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...
