Martin JH; Rosser CJ; Linebach RF; McCullough DL; Assimos DG Department of Urology, Wake Forest University School of Medicine, Winston-Salem, North Carolina 27157-1094, USA. PURPOSE: Performance of coagulation studies for patients undergoing percutaneous nephrostomy (PCN) has been advocated by some investigators. We performed a retrospective study to assess this practice. MATERIALS AND METHODS: The medical records of 180 patients subjected to PCN for various reasons between October 1991 and July 1998 were reviewed. This represents a subset of patients in whom PCN was performed by an experienced interventional radiologist at our institution.
