Under fluoroscopic guidance, a guidewire was advanced alongside the nephrostomy tube, and success was defined by the wire reaching the renal pelvis or ureter. Outcomes were compared to the conventional technique of inserting the guidewire through the nephrostomy tube, and the influence of time since nephrostomy placement on success was assessed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Guidewire passage alongside the nephrostomy tube succeeded in 27 of 33 cases (81.8%). Failures occurred in 6 cases (18.2%), mainly because of tortuous or calcified tracts requiring new access. The conventional through-tube approach succeeded in 32 of 33 cases (97%), but this difference was not statistically significant (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      = 0.10).
