Comparison of morbidity of lumbar flank approach and transperitoneal approach for radical nephrectomy. 
This is a retrospective study comparing the clinical data and morbidity of transperitoneal radical nephrectomy (TRN) and simple nephrectomy.  From 1st January, 1989 to 1st January, 1996 a total of 90 simple nephrectomies and from 1st January, 1996 to 1st August, 1999 a number of 85 TRN were performed at the Department of Urology of the Saint Stephen Hospital.  The analysis of clinical data included operative time, length of analgesics, postoperative hospital stay and blood loss, as well as morbidity.  The mean operative time for TRN was 170 min.,  being 95 min.  for simple nephrectomy.  The mean blood loss for TRN was 250 ml, and 400 ml for simple nephrectomy.  There were different types of morbidity for TRN and simple nephrectomy.  The complications of TRN mean minimal risk and easy correctibility.  Our results demonstrate an overall clear advantage of TRN when compared to simple nephrectomy.
