Effects of Quadratus Lumborum Block on Lower Urinary System Symptoms

Lower Urinary Tract Symptoms Clinical Trial

Official title: Effects of Postoperative Quadratus Lumborum Block on Sub-Urine System Symptoms in Ureteroscopic Lithotripsy Operations: Randomized Controlled Study

Status Active, not recruiting

Clinical Trial Summary

The most common reason for applying to a hospital in the postoperative period due to the double J stent inserted during operations of the uteroscopic lithotripsy is reflected pain (T11-L2). The posterior approximation QL block (QL-P) is known to extend more easily to the thoracic paravertebral cavity or thoracolumbar plane, creating analgesia from T 7' to L 1'. The effects of double J catheter in patients are followed by 'Ureteral Stent Symptom Scoring Survey'. QL-P for postoperative analgesia after URS operations Our primary hypothesis in this prospective, randomized, controlled study is that the symptoms of the sub-urinary system associated with the DJS of the QL-P block will decrease. Our secondary hypotheses in the study are to investigate the effects of the unilateral QL-P block, made under ultrasound guidance, on pain scores that occur after ureteroscopic lithotripsy operations due to unilateral ureteral stones made under spinal anesthesia.

Clinical Trial Description

All patients will be placed in a seated position to apply spinal anesthesia. Patients will be entered into the interspinal distance from the Lumbar(L) 3-L4 spinal interval or the L4-L5 spinal interval with a needle of 25 Gauge Quincke, creating a sensory block at level 0.5% hyperbaric bupivacaine with Trocal(T) 10. After the T 10 level sensory block is formed, patients will be divided into 2 groups. 1. Patients in the group are the control group and will be placed in the lithotomy position for the surgical procedure after the sensory block. 2. In the patients in the group, lateral decubitus position will be given to make quadratus lumborum block. After the skin is prepared sterile, the convex ultrasound probe (SonoSiteMTurbo; FUJIFILM SonoSite, Bothell, WA) will be inserted perpendicular to the spine in the 12th vertebral body and then forwarded to the lateral to view the quaratuslumborum muscle and psoas muscle. In-plane method with the lateral of the probe 22 gauge needle, between the quadratus lumborum muscle and the front layer of the thoracolumbar fascia after the position accuracy is determined with 1-2 mL serum physiolgic, %0.375 Mg of bupivacaine will be injected in 20 ml. The patient will then be placed in the lithotomy position for the surgical procedure. Patients of a blind research assistant to the group distribution are seen on-site in the 1st, 6th, 12th and 24th hours after surgery, postoperative 7. by calling by phone per day, pain intensities will be assessed by 'numerical assessment scale' (Numeric Rating Scala: NRS). For half an hour, 5 mg of tramadol will be added if NRS is above 100 mg. For 48 hours, tramadol, non-steroidal anti-inflammatory consumption will be monitored. In addition, complications such as local anesthesia toxicity, allergy, internal organ injury, postoperative nausea and vomiting, postoperative bleeding will be recorded. In addition, on the 7th post-operative day, the pain level of the patients will be evaluated with NRS and the sub-productive system septomas connected to DJS are evaluated with the ureteralstent symptom scoring questionnaire (while inserted in the stent). In our clinic, approximately 1 month after URS operations, control cystoscopy is performed and ureteral stents are removed. After 5 days of removal of the ureteral stent, the symptoms of the lower urinary system will be questioned with the ureteral stent symptom scoring questionnaire (after the stent is removed). ;
