In an ageing population, long-term nephrostomy is increasingly common for the management of patients who are unfit for definitive treatment to relieve of obstruction. Nevertheless, this carries the burden of inadvertent nephrostomy displacement.

When a patient is admitted urgently with dislodged nephrostomy, traditional management options are to allow the collecting system to dilate again, prior to creating a new track, or to take the patient to a theatre as an emergency and to attempt to insert a guidewire with immediate nephrostomy replacement.1 2 The downside to the former is that collecting system may dilate at a variable rate and sometimes take several days to allow safe reinsertion. Furthermore, a new puncture, which is usually a more invasive procedure than reinserting the nephrostomy catheter via the original track, can also be …
