Abstract:

Objective   To investigate the clinical significance and experience of ultrasound-guided percutaneous nephrostomy (PCN). Methods   Ultrasound-guided PCN was performed on 71 patients with hydronephrosis. 11 patients of them underwent bilateral ultrasound-guided PCN. The clinical efficacy of PCN was observed and analyzed. The renal function of the patients was checked and the urine volume was observed 1 week before and 1 week after percutaneous nephrostomy. Results   Totally 82 PCN procedures were performed on the 71 patients with the primary successful rate of 96.34% (79/82). The renal function of all the patients was improved greatly in 1 week. No one had severe complications or died due to operation complications. Conclusion   Ultrasound-guided PCN is claimed to be a safe, simple, effective procedure with almost no serious complications. This technique has important clinical significance because it can improve renal function definitely.
