title: Laparoscopic versus open bilateral nephrectomy in transplant recipients with medication-resistant hypertension: final results of a multicenter study with 15 years of follow-up.
abstract: BACKGROUND
  The objective of this study was to evaluate the outcomes of laparoscopic bilateral nephrectomy (LBN) compared with open bilateral nephrectomy (OBN) in transplant recipients with medication-resistant hypertension.
  
  
  METHODS
  Between 1994 and 2009, 66 renal transplant recipients underwent LBN due to poorly controlled hypertension. We compared them with 44 previous patients who underwent OBN.
  
  
  RESULTS
  The mean operative times for LBN and OBN were 195.4 ± 60.1 minutes and 145.7 ± 30.2 minutes, respectively (P = .013). The mean hospital stays were 4.2 ± 2.1 in the LBN versus 10.3 ± 3.9 days in the OBN groups; the mean complication rates were 9.1% versus 18.2%, respectively. At follow-up, the blood pressure (mean value 130/90 mm Hg) in 45 patients (68.2%) among the LBN group was well controlled without the need for antihypertensive medications. In 19 patients (28.8%) significantly fewer antihypertensive drugs (1 or 2) were needed compared with the preoperative status. The remaining 2 patients (3%), both of whom had returned to hemodialysis due to chronic transplant rejection, remained on a combination of 3 or more antihypertensive drugs. Among the open surgery group, 23 subjects (52.3%) showed significantly decreased arterial blood pressure without needing medical therapy; 18 patients (40.9%) required 1 or 2 drugs and the remaining 3 (6.8%) were on a combination of 3 or more antihypertensives. The last cohort had returned to hemodialysis due to chronic transplant rejection.
  
  
  CONCLUSIONS
  LBN showed a higher efficacy than open surgery to treat medication-resistant hypertension after renal transplantation, reducing the postoperative trauma and the morbidity rate in high-risk transplant recipients.
