Laparoscopic nephrectomy: comparison of dialysis and non-dialysis patients.

BACKGROUND Laparoscopy is believed to result in possible clinical benefits for the patient. We report our experience with renal laparoscopy in dialysis patients and compare the results with those from non-dialysis patients. METHODS Between December 1994 and April 1997, 19 dialysis patients underwent laparoscopic nephrectomy or nephroureterectomy at our hospital. The group consisted of 11 female and eight male patients (mean age 45 years). In nine patients the indication for nephrectomy was chronic pyelonephritis. Nephroureterectomy for vesicoureteral reflux with recurrent episodes of pyelonephritis or analgesic nephropathy for exclusion of transitional cell carcinoma of the upper urinary tract was considered in nine other patients. Laparoscopic bilateral nephrectomy for drug-resistant hypertension was performed in one patient. In comparison, a consecutive group of non-dialysis patients who had undergone renal laparoscopy was reviewed. RESULTS In the dialysis group, one patient had to be converted to open nephrectomy due to bleeding. Six dialysis patients required blood transfusions compared with none in the non-dialysis group. There were four complications in the dialysis group and two in the non-dialysis group. Both groups had comparable results for operative times, analgesic consumption, postoperative start of oral intake and mobilization, and duration of hospitalization and convalescence. CONCLUSIONS Laparoscopic nephrectomy in dialysis patients has acceptable results. The higher transfusion rate is probably due to a lower preoperative haemoglobin and is not aggravated by possible affects of the clotting system in patients with chronic uraemia.
