Background and Aims Varicocele is formed as a result of dilatation of the pampiniform plexus of the spermatic veins. It was aimed primarily to evaluate the effect of TFP block on pain scores in the postoperative period in patients who had undergone varicocelectomy surgery, and secondarily to evaluate the effect of transversalis fascia plane block(TFPB) block on analgesic consumption.

Methods The study was initiated after the approval of the local ethics committee and 60 patients over the age of 18 who were to undergo varicocelectomy operation, with ASA I-II were included in the study. The patients were randomized with a computer program before the operation and divided into two groups as Transversalis Fascia Plane block group (Group T) and Surgical incision site infiltration group (group I). All operations were performed under general anesthesia with laryngeal mask and microsurgery with subinguinal technique. TFPB and local infiltration blocks (LIB) were applied after surgical suturing without termination of anesthesia. 20 ml of 0.25% bupivacaine was applied for both blocks. Demographic data of the patients, passive and active postoperative VAS scores, need for nonsteroidal anti-inflammatory drugs and rescue analgesia were noted.

Results 60 patients were included in the study. There was no statistical difference between the groups in terms of demographic data. When the active and passive VAS scores(p<0.001), nonsteroidal anti-inflammatory analgesia(p<0.05) and rescue analgesia requirement(p<0.001) were evaluated at all hours, there was a statistically significant decrease in Group T.

Conclusions It was seen that a more effective analgesia could be created with TFPB compared to LIB after varicocelectomy surgery.
