Pseudoaneurysm Formation after Laparoscopic Partial Nephrectomy

The Laparoscopic Partial Nephrectomy (LPN) is the “gold standard” to management of small renal masses (Figure 1) [1,2]. The patient, a 38 year Male at 8th post-operatory day from right upper pole PN, presented at ER with a voluminous gross hematuria (Figure 2). The clinical diagnosis was a renal pseudoaneurysm. The patient was hemodynamically stable, and a medical approach was tried. After 12 hours of clinical management, the hematuria had not stopped. A transfemoral arteriography was done, and the Pseudoaneurysm diagnosis was confirmed (Figure 3). An intravascular embolization was performed (Figure 4) and the hematuria ceased in the day after.
