Abstract

Introduction The local inflammatory process after prostate biopsies can have a negative impact on functional outcomes of radical prostatectomy. There is no evidence in literature demonstrating its impact on radical prostatectomy. Objectives To evaluate the impact of the number of TRUS core biopsies in the surgical morbidity and rate of positive margin on robot assisted radical prostatectomy (RARP). Material and methods A prospectively maintained database of 2,054 RARPs in a single institution. Patients were further grouped into 2 groups based on the number of TRUS biopsy cores (G1 ≤ 12 cores; G2 > 12 cores). Multivariable logistic regression model was applied to analyze the impact of number of cores on complications. Results A total number of 1,042 patients in the group 1 (≤ 12 cores) and 1,012 patients in the group 2 (> 12 cores) were included. The rate of perioperative complications increased with higher number of biopsies (G1 6.4 vs. G2 8.5%; P = .03), but high grade complication (Clavien 3-4) were similar (G1 1.4 vs. G2 2.2%; P = .16). Positive surgical margin rates were similar in both groups (G1 11.8 vs. 9.98%; P = .2). At the multivariable logistic regression analysis shown that G2 had a 39% (OR 0.645) higher rate to experience perioperative complications during RARP. Conclusion Higher number of TRUS biopsy cores (> 12) is associated to higher blood loss and perioperative complications during RARP. Careful preoperative evaluation for those patients underwent multiple biopsies or saturation protocols is mandatory. Application of longer intervals (> 6 weeks) between biopsy and surgery may be advisable to minimize potential risks of surgical complications in patients may benefit from RARP. Further studies are still necessary to confirm these results.
