Safety and complications of percutaneous nephrostomy under ultrasound and dsa guidance in obstructed unary upper tract

Abstract

Aim: to access the safety and complications of Percutaneous Nesphrostomy in obstructed urinary upper tract. Patients and methods: a cross-sectional descriptive study was performed on 45 patients who were diagnosed with pyelonephritis and hydronephrosis due to obstructed urinary upper tract at the Radiology Department, Ha Noi Medical Hospital from 6/2021 to 8/2022. Results: 100% of patients who have hydronephrosis and pyelonephritis taken broad-spectrum antibiotics before performing percutaneous nephrostomy (PCN). Position to drain into renal pelvis: 93.3% from the inferior pole, 6.7% from the middle pole. 91.1% of patients were performed successfully Percutaneous Nephrostomy the first time and 8.9% of patients needed in the second time. The successful rate of Percutaneous Nephrostomy was 100%. Time to complete procedure on average 19.5±4.5 minutes. Bleeding complications accounted for 2.2% (n=1), Sepsis complications accounted 6.7% (n=3). Catheter obstruction was 18% (n=8). The size of the sonde drainage 8F was used for patients with Hydronephrosis and pyelonephritis in grades I and II. The size of the sonde drainage 10-12F was used for patients with Hydronephrosis and Pyelonephritis in grades III and IV. Conclusion: Percutaneous nephrostomy is a minimal, safe, effective treatment procedure.
