OBJECTIVE: To determine what effect the presence of a nephrostomy, left on free drainage, might have on the rate of occurrence of ureteric strictures after ureteric instrumentation. PATIENTS AND METHODS: Eighteen patients were identified in this unit who had had ureteric instrumentation while a nephrostomy was in place. RESULTS: Eight of 11 patients in whom the nephrostomy was left open developed ureteric strictures. None of seven patients in whom the lumen was maintained by stenting and/or clamping of the nephrostomy developed strictures. The strictures needed dilatation and stenting in seven patients and the ureter had to be reimplanted in the other. CONCLUSION: In patients in whom a nephrostomy is in place, the opening should be occluded after ureteric instrumentation or a stent should be inserted if it is to be left on free drainage.
