目的评价对恶性肿瘤继发输尿管梗阻患者应用一步式经皮肾穿刺造瘘法治疗的效果。方法因恶性肿瘤继发输尿管梗阻、肾积水的患者33例,男18例,女15例,平均年龄55岁。在超声引导下,采用一步式经皮肾造瘘直接穿刺引流。结果共穿刺33例患者36个肾脏均获成功,其中一次穿刺成功33个,二次穿刺成功3个。术后均尿液引流通畅,术后l周内肾功能明显改善。未出现严重并发症。结论一步式经皮肾穿刺造瘘法成功率高、创伤小、并发症少,对改善恶性肿瘤继发输尿管梗阻的肾功能不全具有重要临床意义。
Objective To evaluate the effect of one-step percutaneous nephrostomy in patients with malignant tumor secondary to ureteral obstruction. Methods Totally 33 patients with malignant tumor secondary to ureteral obstruction and hydronephrosis, 18 males and 15 females, with an average age of 55 years. Under the guidance of ultrasound, a one-step percutaneous nephrostomy is directly punctured and drained. Results A total of 36 cases of renal biopsy were successful in 33 cases, including 33 cases of successful puncture and 3 cases of successful puncture. Urine drainage were smooth after surgery, l weeks after surgery, renal function improved significantly. No serious complications occurred. Conclusion The one-step percutaneous nephrostomy has a high success rate, small trauma and few complications, which is of great clinical significance for improving renal insufficiency secondary to malignant ureteral obstruction.
