The impact of non-hilar clamping open partial technique performed for the treatment of patients with small renal masses with lower R.E.N.A.L. nephrometry scores on renal functions during the early postoperative period.
OBJECTIVE
Herein, the impact of off-clamp open partial nephrectomy on early postoperative period renal functions were evaluated in patients with low RENAL nephrometry scoring small renal masses.


METHODS
Twenty-three patients (12 women, and 11 men) who had undergone non-hilar clamping open partial nephrectomy in our clinic between the years 2010, and 2013 were retrospectively evaluated. Mean age, body mass index (BMI), operative time, blood loss, renal nephrometry score, mean hospital stay, pre-, and postoperative serum creatinine (Cr), and glomerular filtration rate (GFR) of the patients were assessed.


RESULTS
Mean age, BMI, tumor size, and preoperative renal nephrometry scores were 56.09±10.49 years (36-70 yrs), 24.81±2.44 kg/m(2), 3.68±1.125 cm, and 6.41±1.77 pts, respectively. Mean operative time, intraoperative blood loss, and hospital stay were detected as 139.14±33.60 min, 274.9±77.02 mL, and 4.27±1.12 days, respectively. Preoperative mean serum Cr, and GFR levels were 0.804±0.216 mg/dL, and 93.97±25.83 mL/min/1.73 m(2), respectively. Postoperative 1. day mean serum Cr, and GFR levels were 0.896±0.25 mg/dL, and 85.94±28.85 mL/min/1,73 m(2), while corresponding 3. month-values were 0.81±0.205 mg/dL, and 93.59±21.00 mL/dk/1.73 m(2), respectively. A statistically significant difference was not found between preoperative, and postoperative 3. month- serum Cr, and GFR levels. However, postoperative 3. month-serum Cr, and GFR levels were lower than corresponding values estimated on postoperative 1. day (p<0.016).


CONCLUSIONS
One of the important considerations in partial nephrectomy is to preserve renal functions. Therefore, non-hilar clamping open partial nephrectomy should be taken into consideration for surgeons unexperienced especially in laparoscopic surgery with its lower morbidity, and complication rates.
