背景:为了评估迷你轨道的结果,微型肾镜检查,微型超声探头经皮肾镜取石术治疗输尿管上段和肾结石。
方法:我们收集了53例(55个肾单位)患者的数据,微型肾镜检查,2020年9月至2021年3月之间的微型超声探头经皮肾镜取石术。该研究包括来自12个肾脏的单个和上输尿管结石,来自28个肾脏的多个结石,和15个肾脏的鹿角结石。
结果:平均手术时间为50.6分钟,范围从15到200分钟,而平均碎石和取石时间为17.2min(3-45min)。此外,术后平均住院时间为4.0天(1~7天).此外,排石率(SFR)为89.1%(49/55)。平均血红蛋白下降15.3mg/dL,范围1-32mg/dL。在所有案件中,其中只有4人出现轻微并发症。通过进行亚组分析比较<40mm与≥40mm结石的结局。结果表明,手术持续时间更长(65.2vs.40.2分钟),并发症发生率较高(13.0%vs.3.3%),≥40mm结石亚组SFR较低。
结论:总之,迷你轨道,微型肾镜检查,微型超声探头经皮肾镜取石术是治疗输尿管上段及肾结石安全有效的方法。这对于20-40毫米的石头尺寸尤其重要,显示良好的SFR和较低的并发症发生率。
BACKGROUND: To assess the outcome of the mini-track, mini-nephroscopy, mini ultrasonic probe percutaneous nephrolithotomy for upper ureteral and kidney stones.
METHODS: We collected data of 53 patients (55 kidney units) who underwent mini-track, mini-nephroscopy, mini-ultrasonic probe percutaneous nephrolithotomy between September 2020 and March 2021. The study included single and upper ureteral stones from 12 kidneys, multiple stones from 28 kidneys, and staghorn stones from 15 kidneys.
RESULTS: The mean operative duration was 50.6 min, ranging from 15 to 200 min, whereas the mean lithotripsy and stone removal time was 17.2 min (3-45 min). Moreover, the mean postoperative length of stay was 4.0 days (1-7 days). Besides, the stone-free rate (SFR) of discharge was 89.1% (49/55). The mean hemoglobin drop was 15.3 mg/dL, ranging 1-32 mg/dL. Out of the total cases, only 4 of them displayed minor complications. The outcomes of < 40 mm versus ≥ 40 mm calculi were compared by performing subgroup analysis. The results demonstrated a longer operation duration (65.2 vs. 40.2 min), higher complication rate (13.0% vs. 3.3%), and lower SFR in the ≥ 40 mm calculi subgroup.
CONCLUSIONS: In summary, mini-track, mini-nephroscopy, mini-ultrasonic probe percutaneous nephrolithotomy is an effective and safe method to treat patients with upper ureteral and kidney calculi. This is especially significant for the stone size of 20-40 mm, demonstrating excellent SFR and a lower complication rate.
