Ceylan et al. Journal of Medical Case Reports 2012, 6:339 http://www.jmedicalcasereports.com/content/6/1/339 whose prolonged urinary leakage following percutan- eous nephrolithotomy, which had not stopped although a double pig-tail stent had been inserted, suddenly came to an end with peroral desmopressin treatment. They showed that treatment with oral desmopressin could reduce urinary leakage [9]. In our case, the urinary leakage continued although we inserted a double j stent, but it reduced dramatically during the week following the commencement of oral desmopressin treatment and no complication was observed in the patient. Our study showed that desmopressin can reduce the duration of urinary leakage in these patients. The use of desmopressin may improve the beneficial effect of other procedures such as catheter drainage, ur- eteral stenting, and percutaneous nephrostomy place- ment for incisional urinary leakage. Thus, we have come to the conclusion that patients with prolonged urinary leakage, who do not respond to surgical urinary drainage after renal surgeries, can benefit from desmopressin. We argue that desmopressin medical treatment can be con- sidered an alternative in clinics with many centers and patients and in prolonged clinical studies. Conclusion Desmopressin treatment should be considered a safe al- ternative treatment in prolonged urinary leakage before it becomes chronic, which is an annoying complication in the postoperative period. Desmopressin can be ap- plied orally and it presented no complication in recent blood tests.
