RESUMEN
Objective?To observe the clinical effect of FURS combined with ultrasound guided all seeing needle treatment of low pole renal calculi.?Methods?From January 2016 to January 2017, 63 patients with low pole renal calculi were enrolled in this study. 16 patients with multiple stones and 47 cases with single stones were treated by FURS combined with ultrasound guided all seeing needle. We retrospectively analyzed all the patients clinical data, including the operation time, bleeding volume, stone clearance rate, the incidence of postoperative complications, then assess the safety and effectiveness of the surgical approach.?Results?The operation time was 30 ~ 60 min, the average time was 45 min, postoperative complications in 3 cases, 2 cases of pain; no blood transfusion; 2 cases of percutaneous nephrolithotomy. Postoperative hospital stay wad 2 ~ 3 d, an average of 2 d, postoperative residual stone in 3 cases, 2 weeks after the treatment of external lithotripsy, 1 case of stone clearance rate of 100.0%.?Conclusion?Retrograde FURS combined with ultrasound guided visual puncture for renal calculi is safe, effective and feasible.
