Myth: nephrolithiasis and medical expulsive therapy

Area of Science:

• Urology
• Pharmacology

Background:

• A common medical belief suggests ureteral stones exceeding 5 mm necessitate urological intervention.
• Recent evidence challenges this, indicating larger stones may pass spontaneously.

Purpose of the Study:

• To evaluate the efficacy of medical expulsive therapy for facilitating spontaneous passage of ureteral stones.
• To challenge the traditional 5 mm threshold for intervention.

Main Methods:

• Review of recent findings on medical expulsive therapy for ureteral stones.
• Analysis of the role of tamsulosin and corticosteroids in stone expulsion.

Main Results:

• Medical expulsive therapy, including tamsulosin and corticosteroids, can facilitate spontaneous passage of ureteral stones up to 10 mm.
• This approach can potentially avoid invasive urological procedures.

Conclusions:

• The 5 mm guideline for ureteral stones requiring intervention is outdated.
• A combination therapy of tamsulosin, corticosteroids, analgesics, antibiotics, and hydration is recommended for managing ureteral stones up to 10 mm.
