Investigating a Novel Modifiable Factor Affecting Renal Function After Partial Nephrectomy: Cortical Renorrhaphy
Preserving kidney function during removal of a kidney tumor is becoming increasingly important as rates of chronic kidney disease increase. A novel modifiable factor (suture closure of the defect caused by tumor removal) was discovered on retrospective studies to account for nearly two-thirds of the 15% volume loss commonly seen in operated kidneys. We hypothesize that a randomized controlled surgical trial will show that omitting the suture closure both preserves renal function and will not lead to unreasonable postoperative complications.
The purpose of this study is to evaluate a never before studied modifiable factor affecting renal function after partial nephrectomy: the suture closure of the renal cortex after tumor removal (renorrhaphy).
