Introduction : We report treatment outcomes of mini-incision clampless partial nephrectomy (PN) using soft coagulation (SOFT COAG) without renorrhaphy performed in our institution.
Materials and Methods : Nineteen PN cases were included in the present study. We calculated the split estimated glomerular filtration rate (split eGFR) of both the involved and noninvolved kidney using serum creatinine levels and renal scintigraphy. We analyzed changes in split eGFR from the preoperative period through postoperative day 7.
Results : The mean split eGFR decrease of the involved kidney was 28.5% ± 14.0%. The decrease was greater in the subgroup with ≥8 RENAL nephrometry score. In the noninvolved kidney, an increase of 8.2% ± 12.0% in split eGFR was observed.
Conclusion : Although SOFT COAG enables clampless PN, we found that thermal injury may decrease renal function. Therefore, the indication of clampless PN by SOFT COAG should be re-considered especially in cases with high-complexity tumors.
