title: Comparison of transperitoneal laparoscopic nephrectomy outcomes in atrophic and hydronephrotic kidneys.
abstract: OBJECTIVE
  To compare the results of transperitoneal laparoscopic nephrectomy in patients with atrophic and hydronephrotic kidneys.
  
  
  METHODS
  Clinical data were collected from 35 patients who had undergone laparoscopic nephrectomies for atrophic or hydronephrotic non-functioning kidneys between January 2010 and March 2014. Comparative analysis was carried out between the two groups examining demographic characteristics, imaging modalities, etiology, operative times, port numbers, conversion to open surgery, complications, pre-and post-operative hemoglobin and creatinine values, transfusion rates and length of hospital stays.
  
  
  RESULTS
  Laparoscopic nephrectomy was performed for atrophic kidneys in 20 (57%) patients and for hydronephrotic kidneys in 15 (42%) patients. In the atrophic group, 3 patients (15%) required transfusion because of bleeding but none of the patients required conversion to open surgery. In the hydronephrotic group one patient (6.6%) required transfusion and conversion to open surgery because of bleeding. Both of the groups were similar in terms of postoperative hospital stay but compared to the atrophic kidneys, hydronephrotic ones were associated with a longer total operative times (90.1 min vs. 73.6 min, p=0.03). Any serious complication (except for bleeding) and mortality were not encountered in both groups.
  
  
  CONCLUSIONS
  Laparoscopic nephrectomy is a safe and effective minimally invasive technique that can be used in atrophic and hydronephrotic non-functioning kidneys.
