Clinical Trial Summary

The most common reason for applying to a hospital in the postoperative period is due to the double J stent inserted during operations of the ureteroscopic lithotripsy, which is reflected pain (T11-L2). The posterior approximation QL block (QL-P) extends more quickly 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 the '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 after ureteroscopic lithotripsy operations due to unilateral ureteral stones made under spinal anesthesia.


Description:

All patients will be seated to apply spinal anesthetic. Patients will be inserted into the interspinal space using a 25-gauge Quincke needle from the lumbar (L) 3-L4 spinal interval or the L4-L5 spinal interval, thereby inducing a sensory block at a 0.5% hyperbaric bupivacaine level with a Trocal (T) 10. Once a T-10 level sensory block has been established, the patients will be separated into two groups. As the control group, the individuals comprising Group 1 will be positioned in the lithotomy position after the sensory block for the surgical procedure. Group 2 patients will be placed in lateral decubitus to conduct a quadratus lumborum block. Once the skin's surface has been sterilized, the convex ultrasound probe (SonoSiteMTurbo; FUJIFILM SonoSite, Bothell, WA) will be moved laterally to the lateral to visualize the psoas and quadratus lumborum muscles. The probe will be inserted perpendicular to the spine in the 12th vertebral body. The 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 physiologic, %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. Per phone daily, pain intensities will be assessed by a 'numerical assessment scale' (Numeric Rating Scala: NRS). If NRS is above 3 for half an hour, 100 mg tramadol will be added. For 48 hours, tramadol and non-steroidal anti-inflammatory consumption will be monitored. In addition, complications such as local anesthesia toxicity, allergy, internal organ injury, postoperative nausea and vomiting, and postoperative bleeding will be recorded. In addition, on the 7th post-operative day, the patient's pain level will be evaluated with NRS, and the sub-productive system symptoms connected to DJS are assessed with the ureteral stent symptom scoring questionnaire (while inserted in the stent). In our clinic, approximately one month after URS operations, a control cystoscopy is performed, and ureteral stents are removed. After five days of removal of the ureteral stent, the lower urinary system symptoms will be questioned with the ureteral stent symptom scoring questionnaire (after the stent is removed).

Outcome

Type Measure Description Time frame Safety issue
Primary Quadratus posterior block On the 7th post-operative day, lower urinary tract symptoms due to the ureteral stent will be evaluated with the ureteral stent symptom scoring questionnaire (with the stent in place) (questionnaire 1).
Approximately one month after their operations, patients' lower urinary tract symptoms will be questioned withent symptom scoring survey (after stent removal) (survey 2) (Appendix 2) five the ureteral st days after their ureteral stents are removed.
1 month
Secondary Pain Score To evaluate the patients' postoperative pain scores (7 days) using the Numerical Rating Scale. If NRS is above 3 for half an hour, 100 mg tramadol will be added. 7 days
