Background Bipolar Transurethral Enucleation of the Prostate (B-TUEP) is recommended as a firstchoice treatment for benign prostatic obstruction in prostates >80 ml. Differently, B-TUEP is only considered as an alternative option after TURP for smaller prostates (30-80 ml). The aim of our study is to assess the relation between prostate size and surgical outcomes after B-TUEP. Methods We performed a retrospective analysis of data collected from 172 patients submitted to BTUEP. Patients were segregated according to tertiles of prostate volume (PV) (?60 ml, 61-110 ml, >110 ml). For each group we evaluated enucleation efficacy (enucleated weight/enucleation time), complication rates, urinary and sexual function parameters. Functional and sexual parameters were compared between groups at baseline, 1 and 3 months follow up. Descriptive statistics and linear and logistic regression models tested the association between PV and postoperative complications/outcomes. Results Operative time and weight of enucleated adenomas increased along with prostate volumes (all p?0.01). Enucleation efficacy was higher in men with PV >110 ml compared to other groups (p?0.001). Length of hospital stay, catheterization time and rates of postoperative complications, such as transfusion and clot evacuation rates and bladder neck/urethral strictures, were comparable between groups. Urinary symptoms improved at 1-and 3-months in each group as compared to baseline evaluation (all p<0.01) but they did not differ according to PV. In each group maximum urinary flow and post-void residual volume significantly improved at 3 months compared to baseline (all p?0.01), without differences according to PV. Sexual symptoms were similar between groups at each follow up assessment. At multivariable linear and logistic regression analysis, prostate volume was not associated with postoperative functional outcomes and complications. Conversely, patient's comorbid status and antiplatelet/anticoagulation use were independently associated with postoperative complications. Conclusion According to our findings, B-TUEP should be considered a "size independent procedure" as it can provide symptom relief in men with prostates of all sizes with the same efficacy and safety profile.
