What should I do if a stone is lodged at the urethral opening and cannot pass out?

When a stone is lodged at the urethral opening and cannot be expelled, the following measures can be taken:
1. Pain management: A doctor may prescribe pain-relieving medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or other appropriate analgesics, to alleviate discomfort.
2. Urine flow management: If the stone causes complete obstruction, a urinary catheter may need to be inserted or a cystostomy performed to ensure proper drainage of urine and prevent urinary retention and kidney damage.
3. Stone removal: A doctor may attempt to remove the stone using endoscopic techniques such as urethroscopy or cystoscopy, or use lithotripsy to break larger stones into smaller fragments, making them easier to pass through the urethra.
4. Increased fluid intake: If the stone is small, drinking more water may help flush out the stone through urine. However, this method is suitable only for stones smaller than 0.6 cm in diameter.
5. Medication: Under a doctor's guidance, medications such as stone-expelling granules can be taken. These medications help dissolve and expel stones, promoting their removal.
Avoid attempting self-treatment; never try to crush or forcefully expel the stone yourself, as this may damage the urethral mucosa and lead to more serious complications.
