Articles of sonography or CT-guided percutaneous needle biopsy of the different renal parenchymal disease have been published in the literatures. However, tissue confirmation of the urotract lesion is difficult to be obtained by the percutaneous approach because most of the lesions are small and no definite mass could be demonstrated on imaging studies. Percutaneous nephrostomy is a standard pr...

Percutaneous tube nephrostomy (PTN) placement is associated with bleeding complications in a small proportion of cases. We study a case of inadvertent renal vein catheterization during PTN tube change with catheter right atrial migration treated by fluoroscopically monitored catheter removal.

Patients and methods We retrospectively analysed 47 emergent percutaneous nephrostomies in dilated an non-dilated systems in 35 patients from 2001 to 2012 (range 1 months 14 years), using standard or modified technique. “Standard” technique of PCN was performed using the Seldinger or one-step techniques in dilated and non-dilated systems under Ulrasound control. “Modified” technique was perform...

OBJECTIVE Conduct a prospective randomized single-blind comparison of two nephrostomy catheter designs, evaluating specifically intraoperative placement and postoperative comfort. MATERIALS AND METHODS The single-blind, prospective randomized trial was conducted with institutional review board approval. All patients undergoing percutaneous nephrolithotomy who gave informed consent were random...

OBJECTIVE We wanted to present the results of percutaneous management of ureteral injuries that were diagnosed late after cesarean sections (CS). MATERIALS AND METHODS Twenty-two cases with 24 ureteral injuries that were diagnosed late after CS underwent percutaneous nephrostomy (PN), antegrade double J (DJ) catheter placement and balloon dilatation or a combination of these. The time for mak...

Percutaneous nephrolithotomy (PCNL) is a standard treatment for patients with large or complex kidney stones. The procedure has traditionally included postoperative placement of a nephrostomy tube to allow for drainage and possible reentry. This practice was first implemented after complications incurred after tubeless PCNL in a small patient population. Recently, tubeless PCNL has reemerged as...

Nonvascular intervention of the urinary tract is a well-established uroradiologic subspecialty, which is more important for avoiding invasive open surgery in the age of rising demand about the value of less invasive treatment. Various kinds of nonvascular intervention are recently performed under image-guidance and are as follows: percutaneous nephrostomy, percutaneous nephrostolithotomy, percu...
