Abstract
Partial nephrectomy frequently accompanies serious complications such as secondary bleeding and urinary fistula and these complications result from necrosis of renal cut margin after partial nephrectomy.
We have performed experimental partial nephrectomy to compare the extent of necrosis of renal cut margin after the wedge resection(Group l), the transverse polar resection(Group 2) and the chromic ligature resection(Group 3).
In order to investigate which type of 3 partial nephrectomies cause less complications, 15 adult mongrel dogs were divided into three groups and partial nephrectomy was performed at the lower one quarter of 10 kidneys of 5 dogs in each group.
The gross and microscopic findings of renal cut margin were observed at 1, 2, and 3 weeks after the operation.
The results were as follows;
1. Mean depth of necrosis of the renal cortex at cut margin in Groups 1, 2 and 3 were 1.Ocm, O.2 cm and O.3cm, respectively.
2. Mean depth of necrosis of the renal medulla in Groups 1, 2 and 3 were 1.1cm, O.9cm and O.8cm, respectively.
3. On microscopic examination of the renal cortex at the 3rd week after operation, Groups 2 and 3 showed complete healing of necrosis but Group 1 showed delayed healing with remained necrotic tissue.
From the present experiment it was found that both the transverse polar and chromic ligature resection cause less complications than the wedge resection.
