Brief summary

This is a multicentre randomized controlled trial in comparison of the perineal nerve block approach between the periprostatic block in the pain control in men undergo a transperineal prostate biopsy.

Detailed description

This trial is a prospective, multicentre, randomized controlled study in which all men plan to undergo a transperineal prostate biopsy. This study aims to determine whether the perineal nerve block approach is better than the periprostatic block in the pain control in men undergo a transperineal prostate biopsy.

Masking
TRIPLE (Subject, Investigator, Outcomes Assessor)

Masking description

The participant, the investigator and the outcomes assessor were all masked. Only the care provider who performed the anaesthesia were not blinded but they were not involved in the subsequent prostate biopsy, pain assessment, data collection and data analysis.

Design outcomes

Primary

MeasureTime frameDescription
The pain of the biopsy procedurewithin10 minutes after the prostate biopsyThe pain will be measured by numerical rating scale(NRS), which distributed from 0 to 10. 0 represents no pain, and 10 represents the worst pain imaginable.

Secondary

MeasureTime frameDescription
Changes in blood pressure during biopsy procedureDuring the biopsy procedureThe changes will be measured and recorded by multi-parameter monitoring
Changes in heart rate during biopsy procedureDuring the biopsy procedureThe changes will be measured and recorded by multi-parameter monitoring
Changes in breath rate during biopsy procedureDuring the biopsy procedureThe changes will be measured and recorded by multi-parameter monitoring
The detection rate for prostate cancerwithin 1 month after the biopsyThe detection rate for any of the prostate cancer
The detection rate for clinically significant prostate cancerwithin 1 month after the biopsyThe detection rate for prostate cancer with a ISUP\>2
The pain in 1,6, and 12 hours after the biopsy1,6, and 12 hours after the biopsyThe pain in 1,6, and 12 hours will be measured by numerical rating scale(NRS), which distributed from 0 to 10. 0 represents no pain, and 10 represents the worst pain imaginable.
Anaesthesia satisfaction24 hours after the biopsyA questionnaire with five items :whether the pain during the biopsy was less severe than expected (scores from 0 to 10, where 0 represents far less severe and 10 represents far more severe than expected); whether the pain after anaesthesia was less severe than the pain during anaesthesia (scores from 0 to 10, where 0 represents far less severe and 10 represents far more severe); weather the patient is satisfied with the overall feeling of the biopsy (scores from 0 to 10, where 0 represents the highest level of satisfaction and 10 represents the lowest level of satisfaction); whether the patient would recommend this type of biopsy to other patients (scores from 0 to 10, where 0 represents they would highly recommend it and 10 represents they would definitely not recommend it); and whether the patient would still want to choose this way if they have to undergo another biopsy (scores from 0 to 10, where 0 represents very willing to choose it and 10 represents extreme reluctance).
Adverse eventWithin 1 week after the biopsyAny of the adverse events during the trial
The number of biopsy cores10 minutes within biopsyThe number of biopsy cores
The location of each biopsy core10 minutes within biopsyThe location of each biopsy core
Prostate volumewithin 3 months before the biopsy procedureThe prostate volume will be measured by MRI before biopsy
External manifestation of pain10 minutes within biopsyA questionnaire with five items: the degree of facial expression (0 for no particular expression or smile; 1 for an occasional grimace or frown, a withdrawn expression, or a disinterested expression; 2 for frequent or constant quivering chin or a clenched jaw), the degree of activity (0 for lying quietly or being in a normal position, 1 for slight contractions of the hip muscles or slight movements of hip, 2 for severe contractions of the hip or lifting the hip out of the bed), the degree of voice expression (0 for quiet or normal communication, 1 for an occasional moan or weeping sound, 2 for constant moaning or sobbing and screaming), the degree of pacification (0 for being peaceful and not requiring pacification, 1 for being able to be comforted easily, 2 for being difficult to comfort) and the degree of cooperation (0 for being calm and cooperative, 1 for language resistance, 2 for body resistance).
