It was reported via journal article: "title: reducing pseudoaneurysm and urine leak after robotic partial nephrectomy: results using the early unclamping technique" author(s): joan c.Delto1, peter chang1, sara hyde, kyle mcanally, catrina crociani, and andrew a.Wagner.Citation: urology 132: 130-135, 2019; doi: https://doi.Org/10.1016/j.Urology.2019.05.042.This single institution retrospective review of a prospectively maintained database aimed to present our experience using the early unclamping technique for robotic partial nephrectomy with particular attention to delayed complications, namely pseudoaneurysm and urine leak.We hypothesized that early hilar unclamping allows for improved control of end arteries and renorrhaphy after tumor resection, reducing overall delayed complications after partial nephrectomy with no increased risk of blood transfusion.From aug2009 to oct2018, 463 patients (n=290 male and n=173 female; mean age of 56.8 years [sd 12 years ranging 19 to 88 years]; mean bmi of 29.7 [sd6.2]) underwent robot-assisted partial nephrectomy using early unclamping technique.In the procedure, the cortical edges are then reapproximated using a standard sliding clip renorrhaphy technique: 0-vicryl suture on a ct-1 needle (ethicon inc), with a hem-o-lok clip (teleflex medical) and lapraty in an interrupted fashion.Postoperative complications included blood loss anemia from a trocar injury to an epigastric vessel (n=1) requiring embolization; retroperitoneal hematoma (n=1) requiring transfusion and embolization; and urine leak (n=1) requiring stent and percutaneous drainage of a urinoma.Additional suturing during renorrhaphy and oversewing of arterial bleeders could potentiate additional vessel injury.We attribute our low pseudoaneurysm rate to shallow and accurate placement of figure-of-eight sutures to control arterial bleeders if present as well as closure of dead space within the renorrhaphy bed, occasionally utilizing an autologous fat bolster for larger defects.The early unclamping technique for robotic partial nephrectomy is reliable and safe, with low pseudoaneurysm and urine leak rates which compare favorably to other published techniques.
