The impact of prostate biopsy on urinary symptoms, erectile function, and anxiety.

Transrectal ultrasound-guided prostate needle biopsy (PB) is considered the gold standard for the diagnosis of prostate cancer. Recently, lower urinary tract symptoms and erectile dysfunction have been reported following PB. We reviewed the literature on PB and these symptoms and summarized known findings between these conditions and other variables, such as periprostatic nerve block, saturation biopsy, serial biopsies, and psychological factors associated with PB and cancer. A PubMed search was performed using keywords "prostate biopsy," "complications," "erectile dysfunction," "lower urinary tract symptoms," "anxiety," and "quality of life." Eleven key papers are discussed and personal experience is drawn upon. Based upon available evidence, PB appears to be associated with short-term exacerbation of urinary symptoms in some men, as well as associated with anxiety and temporary erectile dysfunction, without a distinct relationship to periprostatic nerve block or the number of cores biopsied. Additional studies are warranted to determine the definitive etiology of these symptoms and to determine if interventions could reduce patient morbidity. In the interim, patients should be educated and counseled about these risks before undergoing PB.
