Complications following combined transrectal ultrasound-guided prostate needle biopsies and transurethral resection of the prostate

In order to evaluate safety and morbidity aspects of additional systematic prostate biopsies, we have conducted a retrospective review of patients who had undergone transurethral resection of the prostate (TUR-P) combined with additional systemic prostate needle biopsies at the Chang Gung Memorial Hospital. To this end, the records of 80 men presenting consecutively at our institution between February 2001 and January 2004 inclusively were examined. These 80 individuals included patients experiencing obstructive voiding symptoms and those featuring suspicious screening parameters, all of whom were to undergo transurethral resection of the prostate for symptomatic benign prostatic hyperplasia (BPH), all procedures being performed by a single surgeon. A total of 20 ( 25%) specimens were found to be positive for prostate cancer. Cancer was detected in the transrectal prostate biopsy specimen of 16 of 57 men (28%) who had not undergone a previous prostate biopsy, and for four of 23 (17%) who had undergone at least one previous ( benign) biopsy. Mild complications associated with transurethral prostrate resection, such as hematuria and hemospermia, were reported frequently, featuring rates of 10% and 2.5%, respectively; more severe complications being noted far less frequently. Fever, usually of a low grade, was observed post-operatively for six (7.5%) patients, but a prompt return to normal temperature following antibiotic treatment for one day was revealed. Four (5%) patients remained admitted to the hospital for a prolonged period following surgery. A review of the literature concerning transrectal biopsies and TUR-P has shown that surgery-associated complication rates are slightly lower than was the case for our study. Additional systematic prostate biopsies for patients undergoing TUR-P would appear to be a relatively safe treatment procedure. Identification of risk factors for post-surgery complications might further improve the safety of the screening procedure.
