To develop a comprehensive scoring system in addition to the conventionally used prostatic volume (PV), for predicting the difficulty of holmium laser enucleation of the prostate (HoLEP) that may arise with small-to-moderate sized prostate.
We retrospectively reviewed 151 consecutive patients who underwent HoLEP and had a PV less than 120 ml. Based on previous literature, a difficult procedure was defined as a prolonged operative time (OT>90 min) in 88 cases, while the control group (OT≤90 min) consisted of 63 patients. The clinical data, including age, body mass index, PV, intravesical prostatic protrusion (IPP), prostate specific antigen (PSA), prostate specific antigen density, urinary tract infection, microscopic hematuria, prior biopsy, diabetes mellitus, hypertension, history of acute urinary retention, catheter dependency and use of antiplatelet / anticoagulation drugs or 5-alpha reductase inhibitor were compared between the two groups.
Univariate analysis revealed significant differences between the two groups. Multivariate analysis identified three main independent predictors for difficulty, including volume (V) (60-90 ml OR=9.812, P<0.001) (≥90 ml OR=18.173, P=0.01), IPP (I) (OR=3.157, P=0.018), and PSA (P) (≥4 ng/ml OR=16.738, P<0.001). Therefore, a V.I.P. score was developed based on the regression model and ranged from 0 to 7 points. The area under the curve showed preferable predictive ability of the V.I.P. score compared to PV (0.906 versus 0.869).
We developed a V.I.P. score that can accurately predict the difficulty of the HoLEP procedure for PV less than 120 ml in order to optimize clinical outcomes.
