简要总结

The aim of the study is to evaluate the effect of preoperative taking alpha-blockers (tamsulosin or silodosin) on the success rate of ureteral access sheath (UAS) insertion and the degree of ureteral injury during RIRS in non-prestented patients.

The results showed that patients who received alpha-blockers had a higher rate of successful UAS insertion and a lower degree of ureteral injury compared to non-prestented patients. In addition, patients with a BMI greater than 25 kg/m² and those older than 59 years demonstrated a higher success rate of UAS insertion and lower degree of ureteral injury.

结局指标

主要结局

successful of ureteral access sheath insertion

时间窗: Intraoperative

Proportion of patients with successful UAS insertion

Inflammatory markers

时间窗: Baseline and 24 hours postoperatively

Change in in blood Leukocyte count, 10⁹/L C- reactive protein , mg/l

degree of ureteral injury

时间窗: Perioperative

Assessed using the PULS scale.Post-Ureteral Lesion Scale. Grade 0: No injury - intact ureter with no visible damage. Grade 1: Superficial mucosal injury - minor abrasions or erosions without disruption of the ureteral wall. Grade 2: Partial thickness injury - damage involving part of the ureteral wall, without full-thickness perforation; may have localized bleeding. Grade 3: Full-thickness ureteral injury - perforation of the ureteral wall with urine leakage, but the injury is limited in size. Grade 4: Extensive ureteral damage - large perforation with significant tissue destruction. Grade 5: Complete transection or avulsion - full disruption with loss of ureteral tissue, typically requiring complex reconstructive surgery.

postoperative pain

时间窗: 6, 24, and 48 hours postoperatively

Patient-reported pain intensity. The Visual Analog Scale for Pain (VASP) is a widely used, validated tool for the subjective measurement of pain intensity. It consists of a straight line, typically 10 centimeters (100 millimeters) in length, anchored by two verbal descriptors: "no pain" at the zero end and "worst imaginable pain" at the opposite end. Participants rate their current pain level by marking a point along the line that corresponds to their perception of pain intensity. The distance from the zero point to the mark (measured in millimeters or centimeters) quantifies the pain intensity on a continuous scale from 0 to 10 (or 0 to 100).

Factors influencing successful ureteral access sheath insertion

时间窗: Until the completion of the study, on average 1 year

Multivariate analysis of factors influencing successful UAS insetion. BMI of the patient - kg/m² Age of the patient

次要结局

  • Postoperative complications(through study completion, an average of 1 year)
