[Phytotherapy in urology. Current scientific evidence of its application in urolithiasis, chronic pelvic pain, erectile dysfunction and urinary tract infections].

OBJECTIVE To assess the usefulness of phytotherapy in urolitiasis, urinary tract infections, erectile dysfunction (ED) and chronic prostatitis/chronic pelvic pain (CP/CPP). ACQUISITION OF THE EVIDENCE Systematic review of the evidence published until January 2011 using the following scientific terms:phytotherapy, urinary lithiasis, Chronic prostatitis, chronic pelvic pain, erectile dysfunction, urinary tract infection, cystitis and the scientific names of compounds following the rules of the International Code of Botanical Nomenclature. The databases used were Medline and The Cochrane Library.We included articles published until January 2011 written in English and Spanish. We included studies in Vitro/in vivo on animal models or human beings. Exclusion criteria were literature not in English and Spanish or articles with serious methodological flaws. SYNTHESIS OF THE EVIDENCE We included 86 articles selecting 40 that met the inclusion criteria. In Urolitiasis there are few works in humans. The phytate has its main use as prevention and in reducing the growth of residual fragments after extracorporeal shock wave lithotripsy (ESWL). In CP/CPP the only compound that has shown effectiveness was the extract of pollen in a field of multimodal treatment. In DE ther is no evidence for the use of herbal medicine.Most of the works have limitations in the design or low sample size. In urinary tract infections most of the products are diuretics .There is only evidence for the cranberry as prevention in young or pregnant women. It must not be used as a treatment for urinary tract infections. CONCLUSIONS Phytotherapy is usefull in repeat urinary tract infections and the CP/CPP. It has some role in the urolitiasis and lacks useful in the DE.
