PURPOSE: To investigate the efficacy and technical applicability of cavitron ultrasonic surgical aspirator (CUSA)-driven zero- @entity63 open partial nephrectomy in @entity1 with @entity703 . MATERIALS AND METHODS: We prospectively collected data of 13 consecutive @entity1 , who underwent open partial nephrectomy under non-ischemic conditions. @entity5 resection was done using an ultrasonic device (CUSA/SONOCA 300). @entity5 characteristics, perioperative, and postoperative variables were evaluated. RESULTS: The median age was 60.0  years (range 40-76); body mass index 28.0  kg/m(2) (range 22.9-43.3); @entity5 size 37.0  mm (range 11-110  mm). @entity1 were stratified according to the PADUA score into low- (score 6-7; n  -  4), intermediate- (score 8-9; n  -  5), and high-risk (score of >10; n  -  4) groups, and the median score was 9.0 (range 6-13; SD +2.3). The vast majority of @entity703 were diagnosed incidentally (n  -  11; 84.6  %). Median operative time was 175  min (55-270  min); median time of @entity5 extirpation was 12  min (6-25  min); and median @entity190 was 250  ml. Serum @entity1011 , glomerular filtration rate, and hemoglobin were nearly unaltered before and after surgery in 11 cases (84.6  %). Three @entity1 received a blood transfusion (Clavien-Dindo Grade II); one had Grade IIIa complication (insertion of double J stent without general anesthesia); and three had @entity532 (insertion of double J under general anesthesia). CONCLUSIONS: The ultrasonic device demonstrated acceptable hemostatic and resection properties during open partial nephrectomy without @entity63 . Our series showed promising perioperative and postoperative outcomes that may help in maximizing preservation of renal function in partial nephrectomy candidates.
