Complications of ultrasound-guided prostate biopsy peripheral zone only versus combined peripheral and transition...

The main objectives of this study were to reassess complications associated with transrectal ultrasound-guided biopsies (TRUSBx) of the peripheral zone (PZ) and to compare morbidity of exclusive PZ biopsy to morbidity associated with two additional transition zone (TZ) biopsies. We distributed a self-administered questionnaire assessing TRUSBx complications to 883 consecutive patients who underwent two systematic TZ TRUSBx in addition to systematic sextant PZ TRUSBx, and to 383 consecutive patients who underwent exclusive PZ TRUSBx. Of 316 (35.8%) patients subjects to TZ and PZ TRUSBx, 71% experienced hematuria, 63% hematospermia, 39% rectal bleeding, and 2.2% temperature elevation greater than 38°C. Of 137 (35.8%) patients who exclusively underwent PZ TRUSBx, 57%, 62%, 36%, and 1.4% reported these complications, respectively. Symptom duration and severity were similar in both groups. Although we report a substantially higher incidence of biopsy complications than previously published, these complications are self limited and require no intervention. Furthermore there appears to be no significant difference between complication rates associated with exclusive PZ biopsy compared with those associated with two additional biopsies of the TZ.
