Juvet T, Parikh KA, Ball CT, et al. - This study was intended to ascertain whether there is a relationship between patient body habitus as assessed by body mass index, body surface area (BSA), preoperative prostate volume, postoperative specimen weight, and open conversion with cystotomy or perineal urethrotomy (PU) during holmium laser enucleation of the prostate (HoLEP). Between August 3 2018 and February 20 2020, researchers included a total of 300 consecutive patients who had undergone HoLEP by a single surgeon. They recorded patient metrics in a database including age, height, weight, preoperative prostate volume, postoperative specimen weight, catheter dependence, and transfusion requirement. This study's findings demonstrate that men with BMI > 30 kg/m² or preoperative prostate volume > 125 mL should be counseled on the possibility of open conversion with cystotomy or PU. It was shown that the risk may be as high as 10% for patients in the highest quartile of BMI (> 30.5 kg/m²) and BSA (> 2.2m ²), although the overall risk of conversion is low (3%),.
