探讨超声引导下经皮肾置管引流术在肾结核治疗中的应用价值。

选取21例肾结核患者，对置管引流术前及术后的血肌酐、24 h尿量以及血钾进行比较，并对术前及术后并发症情况进行分析。

所有患者行超声引导下置管引流术至术后第7天，平均血肌酐浓度、平均血钾浓度均逐渐下降，均于术后第3天降至正常范围；术后尿量（24 h尿量）明显上升，术后第2天达高峰，然后逐渐下降，至术后第3天接近正常范围；术前与术后第3天的血肌酐浓度、尿量（24 h尿量）、血钾浓度均有明显差别，差异具有统计学意义（t=16.19、-47.95、21.41；P均<0.05）。21例患者术前及术后均无窦道形成，5例患者术前出现胃肠道反应，于术后第2天好转。

超声引导下经皮肾置管引流术应用于肾结核患者，可改善患者肾功能，对肾结核的治疗有重要价值。

To explore the application of percutaneous catheter drainage of the kidney under the guidance of ultrasound in the treatment of renal tuberculosis.

Twenty-one patients with renal tuberculosis were selected for catheter drainage, whose preoperative and postoperative serum creatinine, urine volume, and potassium were compared, and the preoperative and postoperative complications were analyzed.

All patients were treated by ultrasound catheter drainage to the 7th day after operation, and the average serum creatinine and potassium were both gradually declined to the normal range on the 3rd day after operation. The urine volume increased obviously after the surgery, achieving the peak on the 2nd day after surgery, and then decreased gradually to the normal range on the 3rd day after operation. The serum creatinine, urine volume and potassium had obvious differences between before the surgery and on the 3rd day after the surgery. The differences are statistically significant (t=16.19, -47.95, 21.41; all P<0.05). No patient formed fistula before or after surgery. Five patients had gastrointestinal reactions before the surgery, and the reactions improved on the 2nd day after the surgery.

The application of percutaneous catheter drainage of the kidney under the guidance of ultrasound in patients with renal tuberculosis can save renal function of patients and have important value for the treatment of renal tuberculosis.
