The study will include 50 patients aged from 18-45 years in ASA I-II risk group undergoing varicocelectomy operations under elective conditions, randomized with a lottery method. Patients will be informed of the study and included in the study after giving permission with a patient consent form. Patients will be divided into two groups; TAP group (Group T, n=25) and P (Group P, n=25). Both groups will be taken for operation under spinal anesthesia. Those with contraindications for spinal anesthesia, with coagulopathy, with known allergy to the medications used, with infection in the operated area, and those who do not volunteer will be excluded from the study. At the end of the operation, patients in Group T in the supine position will have a USI probe placed at the middle point between the costal edge and iliac crest (within the Petit triangle) after necessary antiseptic conditions are ensured. Then after the abdominal muscle layers are observed, the needle tip will be advanced through the muscle layers and pass the fascia, feeling the fascial click, monitored by USI in controlled fashion. After feeling the second click (passing the internal oblique muscle fascia), a test dose of 0.5-1 ml saline will be administered to determine the localization of the needle tip. Then noting the location, with frequent aspiration local anesthetic agent will be administered to the neurofascial plane for TAP block. Patients in Group P will have adjuvant added to spinal anesthesia. Patients in both groups will have pain scores assessed at 2, 4, 6, 12 and 24 hours postoperative at rest and coughing with VAS (visual analog scale) (pain severity: 0 no pain to 10 most severe pain experienced to date) and values will be recorded. When patients are in pain, analgesic agent will be administered according to patient controlled analgesia protocol. The time of first requirement for analgesic agent and the amount of analgesic agent used in 24 hours will be recorded for patients. Side effects like postoperative nausea, vomiting, or itching will be noted. Additionally, patient satisfaction will be assessed by asking if the surgical method they experienced was bad, moderate, good or very good and recorded.
