Prolonged urinary drainage from nephrostomy tract after percutaneous nephrolithotomy can be treated with oral desmopressin.

Desmopressin has been used in the treatment of nocturnal polyuria, diabetes insipitus and primary nocturnal enuresis. We present a patient who experienced prolonged urinary drainage after percutaneous nephrolithotomy but did not respond to insertion of a double pig-tail stent and was treated instead with oral desmopressin.
