Relationship between complications due to prostate biopsy and the scores of pain and discomfort

Introduction: Transrectal ultrasound (TRUS)-guided prostate biopsy is routinely performed in the prostate-specific antigen era. In this study, we evaluated morbidity and complications observed in patients undergoing TRUS-guided prostate biopsy following intrarectal lidocaine application and the relation of these complications to pain and discomfort.

Patients and methods: Between January 2000 and August 2002, a total of 128 patients underwent TRUS-guided prostate biopsy. The procedure was carried out following an intrarectal application of 10 cm(3) 2% lidocaine gel. Immediately after the biopsy, pain and discomfort scores were determined using a 10-point linear visual analog scale. The patients were seen 10 days later and questioned for complications.

Results: At least one complication was observed in 107 patients (84%). Most frequent complications were macroscopic hematuria (90%), hematochezia (36%), and hematospermia (13%). The mean pain and discomfort scores of the patients were found to be correlated to each other (p < 0.01). The complication-negative group had significantly lower pain and discomfort scores (p < 0.01). The scores of the patients with hematochezia were significantly higher than the scores of the patients with other complications (p < 0.01).

Conclusions: Minor complications like hematuria, hematochezia, and hematospermia are frequently seen in patients undergoing TRUS-guided prostate biopsies. The pain and discomfort scores may be predictors of minor complications, particularly of rectal bleeding.
