- Abstract
Purpose: To clinically and histologically characterize prostatic nodules resistant to morcellation (“beach balls,” BBs). Patients and methods: We reviewed a consecutive cohort of 559 holmium laser enucleation of the prostate (HoLEP) procedures performed between January 2020 and November 2023. The BBs group comprised 55 men (10%) and the control group comprised 504 men (90%). The clinical, intraoperative, outcome, and histologic data were statistically processed for the prediction of the presence of BBs and their influence on the perioperative course and outcome. Results: The BBs group in comparison to the controls was older (75 vs 73 years, respectively, p = 0.009) and had higher rates of chronic retention (51 vs 29%, p = 0.001), larger prostates on preoperative abdominal ultrasound (AUS) (140 vs 80 cc, p = 0.006
E−16 ), longer operating time (120 vs 80 min, p = 0.001), higher weights of removed tissue (101 vs 60 gr, p = 0.008E−10 ), higher complication rates (5 vs 1%, p = 0.03), and longer hospitalization (p = 0.014). A multivariate analysis revealed that larger prostates on preoperative AUS and older age independently predicted the presence of BBs which would prolong operating time. ROC analyses revealed that a threshold of 103 cc on AUS predicted BBs with 94% sensitivity and 84% specificity. BBs were mostly characterized histologically by stromal component (p = 0.005). Conclusions: BBs are expected in older patients and cases of chronic retention. Prostatic volume is the most reliable predictor of their presence. They contribute to prolonged operating time and increased risk of complications. The predominantly stromal composition of the BBs apparently confers their resistance to morcellation.
