Open partial nephrectomy with no clamping of the pedicule: a good surgical option in treatment of renal cancer.

The aim of the present work was to describe authors' surgical experience using the partial nephrectomy technique without intraoperatory pedicle clamping for masses even up to 4 cm of size. METHODS: The study enrolled 96 patients with an average age of 59.7 years, who underwent partial nephrectomy without pedicle clamping. The average dimensions of the masses treated were 3.7x3x3.8. In preoperative and in postoperative time creatinine, hemoglobine, hematocrit and platelets were monitored. The follow-up was of 1-3-6 months. At the third month postoperatively a renal US scan was performed, together with a control CT scan and at the sixth month of follow-up the patients underwent also a control Tc99/DMSA renal scintigraphy in back, front, oblique and right posterior oblique left rear projections. RESULTS: Surgery and anesthesia time have been respectively of 1 h 51 min e 2 h 30 min. In the postoperative time the average values were: creatinine 1.46 ng/mL (±0.45), hemoglobin: 11.25 g/dL (±1.6), hematocrit: 36.4 % (±3), platelets: 205 x 103 (±45 x 103). At follow-up at 1-3-6 months the average values were: creatinine 1.16 ng/dL (±0.66), hemoglobin 14.13 g/dL (±0.13), hematocrit 42.43% (±1.03), platelets 204 x 103 U/L (±1.66 x103). After six months the renal function demonstrated intraparenchymal homogeneous distribution of the drug in all the patients, with a 7% of difference of relative uptake by the operated kidney than the healthy controlateral one. CONCLUSION: The partial nephrectomy without intraoperative pedicle clamping can be a good therapeutic option for the treatment of kidney cancer for masses even up to 4 cm of size. The follow-up should be longer to assess oncological results.
