[Renal artery pseudoaneurysm after partial nephrectomy. Diagnosis, treatment and literature review].

Between May 2006 and December 2008, we performed 9 laparoscopic partial nephrectomies (LPns) in our Department. We report the case of a 61-year-old male incidentally diagnosed with a 2.5-cm tumor located in the lower pole of the right kidney. LPn was performed with a duration of surgery of 220 min., an ischemia time of 32 min., and a bleeding volume of 200 ml. Resection was performed with a cold scalpel, and leaving a 1-cm safety margin. Posteriorly, the urinary tract and surgical bed were sutured with polyglactin 3-0, adding Floseal® to the resection bed and placing a Surgicel® membrane. Parenchymal suturing was carried out with polyglactin 1-0 sutures and Hemo-locks® to maintain tension. The histopathological diagnosis was clear cell carcinoma with areas of papillary growth, corresponding to Fuhrman grade II. The tumor measured 2.7 cm in size, and the surgical margins, capsule and perirenal adipose tissue were free of tumor invasion. After surgery the patient presented mild hematuria which intensified 24 hours later, coinciding with the start of walking – requiring continuous lavage and the transfusion of two red cell concentrate units. The patient was discharged on the fourth postoperative day without a catheter. Renal artery pseudoaneurysm after partial nephrectomy. Diagnosis, treatment and literature review
