目的:探讨在B超引导下经皮肾镜术治疗肾下盏结石的可行性和安全性。方法:对16 例肾下盏结石患者采用经皮肾镜术治疗。结石大小(0.8 cm×1.2 cm)~(1.6 cm×2.3 cm),平均1.3 cm×1.8 cm。并发有肾盏轻度积水9例,无肾盏积水7例。曾行ESWL治疗10例。结果:手术均获得成功,手术时间25~50 min,平均38 min。出血15~40 ml,平均30 ml。无一例发生大出血、漏尿及临近器官损伤等并发症。术后2周复查腹部平片未见结石残留。结论:在B超引导下经皮肾镜术治疗肾下盏结石具有简单、安全、创伤小、成功率高等优点,克服了患者ESWL治疗后等待排石和结石残留等不足。
Objective: To investigate the feasibility and safety of percutaneous nephrolithotomy in the treatment of lower calyx stones under B-guided ultrasonography. Methods: Percutaneous nephrolithotomy was used in 16 patients with lower calyx stone. Stone size (0.8 cm × 1.2 cm) ~ (1.6 cm × 2.3 cm), an average of 1.3 cm × 1.8 cm. Concurrent with mild calculus 9 cases of calyceal, hydronephrosis without water in 7 cases. ESWL treatment of 10 cases. Results: All the operations were successful. The operation time was 25-50 min with an average of 38 min. Bleeding 15 ~ 40 ml, an average of 30 ml. No case of major bleeding, leakage of urine and adjacent organ damage and other complications. Two weeks after the operation, there was no residual stones in the abdominal plain film. Conclusion: Percutaneous nephrolithotomy under the guidance of B-ultrasound is simple, safe, less invasive and has a higher success rate. It overcomes the shortcomings of patients waiting for row of stones and residual stones after ESWL treatment.
