Abstract

  Influential factors of postoperative renal function were examined during the first year of 118 cases of laparoscopic partial nephrectomy. The average of age（years old）and renal ischemic time（min）of all cases were 59.5±12.3 and 44.4±15.9, respectively. The preoperative eGFR（estimated glomerular filtration rate）was 81.55±22.57，eGFR immediate after operation was 51.63±14.46，eGFR one month after operation was 68.99±17.35，and eGFR 12 months after operation was 67.87±16.43. The ΔeGFR（（preoperative eGFR－postoperative eGFR）/preoperative eGFR×100%）immediate after operation was －35.81±11.72，ΔeGFR one month after operation was －14.13±14.67，and ΔeGFR 12 months after operation was －11.10±13.53. It was concluded that the significant influential factors of postoperative renal function over a month were age, renal ischemic time（IT）, tumor size, and manitol injection. And those over 12 months were age and renal ischemic time.
