PURPOSE: To determine whether the use of different bipolar resources is associated with different results on tissue and perioperative parameters in patients undergoing bipolar transurethral bladder tumor resection (bTURBT).
METHODS: In this single-center prospective study, patients diagnosed with bladder tumor randomized to undergo TURBT either with a Gyrus PlasmaKinetic system (n = 62) or Olympus TUR in saline (TURis) system (n = 51). Primary endpoint was to evaluate the alteration of patients' perioperative parameters, while secondary aim was to assess the thermal effect of these 2 different bipolar devices on the resected tissue samples by a grading system determined by tissue characteristics.
RESULTS: One hundred thirteen patients were randomized in the study, and 43 were excluded from the analysis due to the exclusion criteria. There were no significant differences between the groups in terms of mean age, tumor site, number of tumors, operative time, alteration in hemoglobin or hematocrit, blood transfusion rate, catheterization time, and postoperative stay. On the other hand, the ratio of obturator jerk was significantly higher in the Olympus TURis group (p = 0.028). The histopathological analyses of both groups determined muscularis propria and cautery artifact presence without a statistically significant difference (χ2: 0.476, p = 0.788).
CONCLUSION: Although the perioperative complications of bTURBT are low in nature, bladder perforation resulted from obturator jerk still poses a risk for extravesical tumor implantation. Urologists should be aware of this risk especially when they are using a TURis system.
