Intraprostatic Anesthesia During Transperineal Prostate Biopsy (PRO-PAIN)
The Effect of Intraprostatic Local Anesthesia on Pain Perception During Transperineal Prostate Biopsy Under Local Anesthesia
Transperineal prostate biopsy has become the standard method for diagnosing prostate cancer because of its favorable safety profile and low infectious complication rates. However, pain and discomfort during the procedure remain important concerns that may negatively affect patient satisfaction and willingness to undergo repeat biopsy when necessary.
This prospective randomized controlled study aims to evaluate whether the addition of intraprostatic local anesthesia to standard perineal local anesthesia reduces pain during transperineal prostate biopsy. Fifty patients undergoing prostate biopsy under local anesthesia will be randomized into two groups. The first group will receive standard perineal local anesthesia, while the second group will receive additional intraprostatic local anesthesia.
Pain severity will be assessed before, during, and after the procedure using a visual analog scale (VAS). Anxiety and depression levels will be evaluated preoperatively using the Hospital Anxiety and Depression Scale (HADS). Patient-related factors, procedural characteristics, and post-procedural outcomes will also be recorded to identify factors associated with pain perception.
The results of this study may help optimize local anesthesia techniques and improve patient comfort during transperineal prostate biopsy.

Detailní popis
Transperineal prostate biopsy is currently considered the preferred approach for prostate cancer diagnosis because of its low risk of infectious complications and favorable safety profile. Despite these advantages, pain experienced during the procedure remains a significant concern and may adversely affect patient satisfaction, procedural tolerance, and acceptance of repeat biopsy when clinically indicated.
Pain during prostate biopsy is primarily related to the rich autonomic innervation of the prostatic capsule and stroma. Perineal local anesthesia is commonly used to reduce procedural discomfort; however, pain may still occur, particularly during needle sampling of the prostatic parenchyma. Intraprostatic local anesthetic infiltration has been proposed as an adjunctive technique to provide more comprehensive analgesia by directly targeting the biopsy area. Previous studies have suggested that the addition of intraprostatic anesthesia may further reduce pain during prostate biopsy procedures.
The objective of this prospective randomized controlled study is to investigate the impact of intraprostatic local anesthesia on pain perception during transperineal prostate biopsy performed under local anesthesia. In addition, the study aims to evaluate the association between procedural pain and patient-related factors, including anxiety and depression levels assessed by the Hospital Anxiety and Depression Scale (HADS), as well as clinical and procedural characteristics.
The findings of this study may contribute to the optimization of local anesthesia protocols and improve patient comfort during transperineal prostate biopsy.

Aktivní komparátor: Perineal Local Anesthesia
Participants receive perineal local anesthesia consisting of infiltration of the perineal skin and subcutaneous tissues using a mixture of 5 mL prilocaine, 5 mL bupivacaine, and 10 mL normal saline before transperineal prostate biopsy.
|
Prilocaine is used as part of the local anesthetic mixture administered for perineal local anesthesia in both groups and for intraprostatic local anesthesia in the experimental group.
Bupivacaine is used as part of the local anesthetic mixture administered for perineal local anesthesia in both groups and for intraprostatic local anesthesia in the experimental group.
Participants receive perineal local anesthesia consisting of infiltration of the perineal skin and subcutaneous tissues using a mixture of 5 mL prilocaine, 5 mL bupivacaine, and 10 mL normal saline before transperineal prostate biopsy.
Participants undergo standard transperineal prostate biopsy under local anesthesia according to the institutional biopsy protocol.
A transrectal ultrasound (TRUS) system is used to provide real-time ultrasound guidance during transperineal prostate biopsy.
The TRUS probe is inserted into the rectum to visualize the prostate and guide accurate needle placement through the perineum for systematic prostate biopsy under local anesthesia.
The device is used in both study groups.

Experimentální: Perineal Plus Intraprostatic Local Anesthesia
Participants receive standard perineal local anesthesia plus intraprostatic local anesthesia consisting of 5 mL of the same anesthetic mixture administered equally to both prostatic lobes before transperineal prostate biopsy.

Pain During Transperineal Prostate Biopsy
Časové okno: During the biopsy procedure
|
Pain severity during transperineal prostate biopsy will be assessed using the Visual Analog Scale (VAS), a patient-reported pain scale ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst pain imaginable.
Higher scores indicate greater pain severity.
Pain scores will be compared between participants receiving perineal local anesthesia alone and those receiving additional intraprostatic local anesthesia.
