Institute of Human Anatomy - Kidney Stones - Will they pass?
The discussion focuses on the size of kidney stones and their ability to pass through the ureter without surgical intervention. Stones smaller than 5 mm typically pass naturally without much intervention. For stones between 5 and 10 mm, medical management with medications like Flowmax, an alpha blocker, is often sufficient to facilitate passage. Stones larger than 10 mm may require surgical intervention due to their size and potential to cause pain and obstruction. An example stone measuring about 7 mm was discussed, which could likely pass with medical management alone, including the use of Flowmax and pain management strategies.
Key Points:
- Kidney stones under 5 mm usually pass naturally without intervention.
- Stones between 5-10 mm may require medication like Flowmax to aid passage.
- Stones over 10 mm often need surgical intervention due to size.
- Flowmax is an alpha blocker that helps facilitate stone passage.
- Pain management is crucial for stones that are passing naturally.

2. 📏 Measuring Kidney Stones
- An example of kidney stone measurement was demonstrated using a real patient case, highlighting practical application.
- The stone was notably larger than the ureter, underscoring the need for potential medical intervention to prevent complications.
- Measurement tools and techniques were briefly mentioned, emphasizing accuracy and precision in assessing stone size.
- The importance of accurate measurement is linked to determining the appropriate medical approach, such as surgical removal or alternative treatments.
3. 🩺 Treatment Protocols for Passing Stones
- Stones under 5 mm typically pass without significant intervention.
- For stones between 5 mm and 10 mm, medical therapy using alpha-blockers can facilitate passage by relaxing ureter muscles.
- Stones larger than 10 mm often require surgical intervention, such as shock wave lithotripsy or ureteroscopy.
- Pain management includes NSAIDs or opioids depending on pain severity.
- Hydration is crucial; patients are advised to increase fluid intake to at least 2 to 3 liters per day.
- In cases where infection is present, antibiotics are prescribed to prevent complications.
4. 💊 Medical Management with Flowmax
- Flowmax is used as a non-surgical intervention for stone passage.
- Flowmax acts as an alpha blocker medication, facilitating the passage of stones by relaxing muscles in the urinary tract.
- Recommended for stones between 5 and 10 mm in size, Flowmax provides an alternative to surgical procedures.
- While effective, potential side effects include dizziness and a drop in blood pressure, necessitating careful patient monitoring.
- Compared to other alpha blockers, Flowmax has shown a favorable patient outcome with a higher rate of stone passage.
- Clinical studies suggest a significant improvement in stone passage rates, with Flowmax increasing the likelihood by up to 20% compared to placebo.
5. 🤔 Evaluating Stone Passage Possibility
- Stones larger than 10 millimeters typically require surgical intervention.
- A stone measuring approximately 7 millimeters is likely to pass with medical management.
- Medical management includes the use of Flowmax and pain management strategies.
