It is usually related to the suture line not being watertight. The contact between urine and the edges of the wound also delay healing of the wound. In this situation, the first thing to do is to break the contact between the wound and the urine by inserting an adequate stent. Sometimes, this process is not enough. We approached this problem with a different treatment method for a case involving prolonged drainage. Case presentation: A 52-year-old Caucasian woman who presented at our clinic with right flank pain was operated on due to a renal hydatic cyst, and cyst removal was performed. On follow-up, prolonged urinary leakage was observed and a desmopressin treatment was started on the patient. Drainage was greatly reduced after desmopressin was started and there was no drainage on the fifth day. Conclusion: Prolonged extravasation is a bothersome situation and there can be many reasons for this. Whenever traditional approaches are not enough, oral desmopressin therapy can be started reliably if there are no contraindications for the patient. Eventually, contact between urine and the suture site will cease and therefore the fever and healing time will be shortened. Keywords: Desmopressin treatment, Hydatic cyst, Renal leakage Introduction Urine leakage and urinoma occur as a result of the dis- ruption of the urinary collecting system at any level from the calyx to the urethra. Persistent urine leakage is fre- quently seen following iatrogenic injuries such as open and/or laparoscopic renal surgery and percutaneous nephrolithotripsy [1-3]. Dealing with urine leakage gen- erally involves some applications, such as catheter drain- age, ureteral stenting and percutaneous nephrostomy placement with open repair versus nephrectomy which is reserved for persistent leakage [1]. However, to the best of our knowledge, the effectiveness of medical ther- apy in urinary leakage has not been mentioned previ- ously. We claimed that reduction in urinary output can accelerate improvement of urinary leakage. In an effort to test this hypothesis, we used desmopressin, which has * Correspondence: ceylancavit@yahoo.com Clinic of Urology, Türkiye Yüksek Ihtisas Training and Research Hospital, Ankara, Turkey antidiuretic effects and can decrease urinary output. Thus, we report our initial experience regarding the ef- fect of desmopressin in reduction of urinary leakage dur- ation following urological surgeries. Case presentation In the examination of a 52-year-old Caucasian woman with a 2-year history of right flank pain and lower urin- ary tract symptoms, a cystic mass was observed in her right kidney in ultrasonography. The cystic mass was diagnosed as a renal hydatic cyst in computed tomog- raphy. The patient was hospitalized with the diagnosis of renal hydatic cyst and no abnormality was found in la- boratory and urine testing. No laboratory analysis was performed for a hydatic cyst; however, a renal hydatic cyst was diagnosed as a result of radiological findings. The patient’s history revealed no close relationship with animals. It was learned that the patient received medical treatment because of cerebrovascular disease and that she had no neurologic deficit for the time being.
