Résumé
Percutaneous nephrostomy is widely used for the diagnosis and treatment of various urinary tract diseases, such as ureteral fistula, stenosis, and percutaneous nephrolithotomy, and the relief of urinary obstruction. Suprapubic cystostomy is also known as a good method for bladder drainage in patients with lower urinary tract obstruction or injury and neurogenic bladder. Despite the frequent use of these procedures, reports in the literature are insufficient for an interventional radiologist to understand the procedures easily and thoroughly. In this article, the indication, anatomy, placement, and postoperative management of percutaneous nephrostomy and suprapubic cystostomy have been described, explaining that the procedures are safe and effective.
