Objective: To evaluate whether 2 similar en bloc thulium laser enucleation of the prostate (ThuLEP) techniques can influence surgical complications and outcomes. Material: Within 2 institutional databases 164 men who underwent 2 different en bloc ThuLEP techniques were compared using propensity scores. With the first technique prostatic lobes were all enucleated en bloc, whereas, with the second the median lobe was enucleated first and the lateral lobes were enucleated en bloc thereafter. All patients were evaluated at baseline and 6 months after surgery with PSA, Qmax, and self-administrated IPSS. Operative data and 30-day postoperative complications were gathered. Results: Surgical time and 24-hour blood loss were similar between 2 groups (55 vs 55 minutes, P.97288; −0.9 vs −1.3 g/dL, P.112 respectively). Median hospital stay after surgery was 3 days in both groups (P.3251). IPSS and Qmax improved equally in both groups (median 3 vs 3, P.941; 19.17 vs 20.63 mL/s, P.8232 respectively). Early complications were mild to moderate (Clavien I 12.2% vs 12.2%; Clavien II 3.6% vs 4.8 4 %; Clavien IIIb 1.2% vs 2.4%). Conclusion: Our results show that en bloc ThuLEP approaches appear feasible, have similar complications and outcomes and can be considered surgeon-independent techniques. En bloc ThuLEP may be proposed even for laser-naïve urologists as an alternative to the original 3-lobe technique.
