Phytotherapy in Urolithiasis: An Updated Overview of Current Knowledge.

Urolithiasis is one of the most burdensome urinary tract conditions with a prevalence ranging from 1% to 20%. Approximately half of the patients experience a recurrence, while 10% face multiple stone episodes. Long before the advent of surgical treatment options, herbal therapy, or phytotherapy, had been used for both the prevention and management of urolithiasis. Recently, interest in phytotherapy has been rekindled due to the limitations associated with modern urolithiasis treatment, the limited options for conventional medical therapy, and the added cost of interventions for stones. While research on phytotherapy is still limited, it is ongoing and is yielding promising results. In order to capture the current trend in phytotherapy for urolithiasis, we performed a narrative review from data collected and synthesized from electronic databases, with a specific focus on randomized human studies. Our analysis revealed that the use of various herbal medicines and phytotherapy, either as mixtures or as sole plant extracts, in urolithiasis is on the rise and is mainly utilized as complementary therapy to conventional treatment. Although most studies demonstrate the effectiveness of phytotherapy in reducing stone size and facilitating stone expulsion, several questions regarding specific dosages, mechanisms of action, drug interactions, treatment duration, and types of stones that respond to phytotherapy remain unanswered. This review aims to summarize the current knowledge surrounding the role of phytotherapy in urolithiasis and to determine its role as a primary or complementary treatment alongside traditional treatment options. Ultimately, further research is essential to clarify the abovementioned unresolved issues, overcome the existing challenges, and optimize the best possible phytotherapy strategies and timing for dissolving specific types of stones with these regimens.
