ABSTRACT To investigate the effect of pre-procedural waiting period and anxiety level on pain perception during transrectal ultrasound-guided prostate biopsy.
Sixty patients who had undergone transrectal ultrasound-guided prostate biopsy were enrolled in this prospective study. The subjects were asked to fill out the State-Trait Anxiety Inventory Scale-1 to measure the level of state anxiety at three times: 1) at the time of the procedure request, 2) before the procedure, and 3) before getting the result. Just after biopsy, the patients were asked to fill out a visual analog scale to evaluate pain perception resulting from the biopsy.
The mean pre-procedural level of state anxiety score was well correlated with the visual analog scale score (r=0.498; P < 0.001). The mean level of state anxiety scores before biopsy (39.7±9.4) and before getting the result (39.9±8.4) were significantly higher than the mean level of state anxiety score when the procedure was requested (31.4±7.9) (P < 0.001 for both). The patient group was divided into two subgroups according to the waiting time between the request and the procedure itself; the cut-off value between the short and long groups was 10 days. The difference between the mean visual analog scale scores from transrectal ultrasound-guided prostate biopsy patients with the short (n=23, 1.49±0.95) and long (n=37, 2.35±1.12) waiting periods was statistically significant (P = 0.003).
In conclusion, performing the transrectal ultrasound-guided prostate biopsy procedure as soon as possible and using more effective anesthetic methods, especially for patients with high level of state anxiety scores, may have a positive impact on patient tolerance.

    ABSTRACT: Biopsy of the prostate is a common procedure with minor complications that are usually self-limited. However, if one considers that millions of men undergo biopsy worldwide, one realizes that although complication rate is low, the number of patients suffering from biopsy complications should not be underestimated and can be a clinically relevant problem for healthcare professionals. In this review, the authors present diagnosis and management of postbiopsy of prostate complications. Bleeding is the most common complication observed after prostate biopsy, but the use of aspirin or nonsteroidal anti-inflammatory drugs is not an absolute contraindication to prostate biopsy. Emerging resistance to ciprofloxacin is the most probable cause of the increasing risk of infectious complications after prostate biopsy. Even though extremely rare, fatal complications are possible and were described in case reports.

    ABSTRACT: Prostate biopsy is commonly performed for cancer detection and management. The benefits and risks of prostate biopsy are germane to ongoing debates about prostate cancer screening and treatment. To perform a systematic review of complications from prostate biopsy. A literature search was performed using PubMed and Embase, supplemented with additional references. Articles were reviewed for data on the following complications: hematuria, rectal bleeding, hematospermia, infection, pain, lower urinary tract symptoms (LUTS), urinary retention, erectile dysfunction, and mortality. After biopsy, hematuria and hematospermia are common but typically mild and self-limiting. Severe rectal bleeding is uncommon. Despite antimicrobial prophylaxis, infectious complications are increasing over time and are the most common reason for hospitalization after biopsy. Pain may occur at several stages of prostate biopsy and can be mitigated by anesthetic agents and anxiety-reduction techniques. Up to 25% of men have transient LUTS after biopsy, and <2% have frank urinary retention, with slightly higher rates reported after transperineal template biopsy. Biopsy-related mortality is rare. Preparation for biopsy should include antimicrobial prophylaxis and pain management. Prostate biopsy is frequently associated with minor bleeding and urinary symptoms that usually do not require intervention. Infectious complications can be serious, requiring prompt management and continued work into preventative strategies.

    ABSTRACT: The aim of the present study was to compare two analgesic techniques for transrectal ultrasound (TRUS)-guided biopsy: diclofenac patch versus periprostatic nerve block with 1% lidocaine. To study the efficacy of and compare diclofenac patch and periprostatic nerve block as analgesia in TRUS-guided prostate needle biopsy. In total, 60 patients were prospectively randomized into three groups: those in whom a diclofenac patch was used (n = 20), those in whom periprostatic nerve block was used (n = 20), and a control group (n = 20). Prostate biopsy was performed after administration of analgesia according to group. The three groups were similar in terms of age, prostate volume, and PSA (prostate-specific antigen) levels. Pain scores were significantly lower in the nerve block group (P = 0.000) at the time of biopsy until 2 h postprocedure, but not at 4 h postprocedure (P = 0.068). No significant difference in pain score was observed in the diclofenac patch group at the time of biopsy (P = 0.106) as compared to the control group, but the diclofenac patch provided adequate pain relief 1 h (P = 0.000), 2 h (0.000), and 4 h (0.002) postprocedure. No significant difference was observed in pain score between the nerve block (P = 0.520) and control groups (0.057) at probe insertion. The pain score at 4 h was significantly lower in the patch group compared to the nerve block and control groups. Periprostatic nerve block provides superior analgesia for TRUS-guided biopsy. Diclofenac patch is useful as an adjunct.
