Abstract

<p>  To determine predictors of beach balls (BB) during HoLEP.</p><p>  Methods : Our 248 HoLEP cases were retrospectively reviewed. Patients were classified into BB (n=51) and non-BB (n=197) groups. We evaluated the relationship between the presence of BB and clinical factors, including age, BMI, PSA, estimated prostatic volume, dutasteride treatment, imaging findings and pyuria. The type of morcellator tube was also analyzed.</p><p>  Results : The 51patients with BB demonstrated a 27-minute longer morcellation time, significantly increased median PSA (4.69 vs 6.84, p = 0.016) and prostate volumes (53.1 vs 81.9, p＜0.001). On logistic regression analysis, prostatic volume was significantly associated with BB (OR 1.03, p＜0.001), though PSA wasn’t independent after adjustment. 2nd generation tubes had a 3.69 times (p=0.005) higher risk for BB compared to 1st generation.</p><p>  Conclusions : The presence of BB requires time-consuming morcellation. Prostatic volume and tube type were associated with a higher risk for BB.</p>
