Image-guided percutaneous nephrostomy is a relatively safe and successful procedure for access to the renal collecting system for multiple purposes including relief of urinary obstruction, urinary diversion, access for endourologic procedures, and diagnostic testing. Although placing a percutaneous nephrostomy catheter is most times straightforward, providing immediate benefit for the patient and satisfaction for the practitioner, there can be situations that make the procedure more difficult or risky. A thorough review of the patient's imaging and medical record will help to set a path for success. However, there may be innuendos and unforeseen circumstances that occur. Having knowledge of most of these "stumbling blocks" and how to deal with them will keep you on the path. This paper serves to fill some of that mental file with the aim to increase clinical success.
