Abstract

Purpose: To evaluate the safety and clinical efficacy of an antegrade approach in the removal of double J ureteral stents via preexisting nondilated nephrostomy routes under fluoroscopic guidance. Materials and Methods: Under fluoroscopic guidance and local anesthesia, antegrade removal of 39 ureteral stents in 27 patients was attempted by using a snare or basket. Indications for percutaneous stent removal included the presence of a preexisting nephrostomy route (n = 8), a surgical history resulting in an inaccessible retrograde route (n = 8), urethral stricture (n = 5), upward stent migration (n = 2), inability to obtain a lithotomy position (n = 1), fragmentation of the proximal stent (n = 1), and inability to find the ureteral orifice with a cystoscope (n = 2). Results: Thirty-seven of the 39 stents (95%) were successfully removed by using a snare or basket. Two stents (5.1%) could not be removed with a snare or basket because they were embedded against the renal calyx or pelvis. There were no major complications. Blood clot formation or laceration or tract leakage of the pelvicalyceal system occurred in six and two patients, respectively, all of which resolved spontaneously. Conclusions: Percutaneous antegrade removal of double J ureteral stents with a snare or basket via a nondilated nephrostomy route is effective without major complications in patients with an available nephrostomy route or an inaccessible retrograde option.
