The effect of prostatic tissue density on the perioperative outcomes of Holmium laser enucleation of prostate (HoLEP): a pilot study

Hawk® JAWS versus Lumenis® VersaCut prostate morcellation devices: A comparative study and comprehensive literature review

“…Similar to our results, morcellation efficiency was 5.4±2.9 g/min, and morcellation time was 11.2±3.9 min in that study (23). Morcellation time has been previously shown to positively correlate with prostatic tissue density (ρ= 0.272, p= 0.0005) (12). As there is no difference between the prostate densities between the groups, we believe it provides more accurate comparisons of morcellation efficiency and morcellation time in our study.…”

“…The efficiency of morcellation (enucleated prostate weight/morcellation time, morcellation time (min), total operation time (min), enucleation time (min), enucleated tissue weight (g), the efficiency of enucleation (enucleated prostate weight/enucleation time) (g/min), densities of the removed prostate tissues and perioperative complications associated with the use of a morcellator were recorded perioperatively. The technique for prostatic tissue density measurement has been previously described (12). Catheterization time (hours) and hospitalization time (hours) were recorded postoperatively.…”

Morcellation After Endoscopic Enucleation of the Prostate: Efficiency and Safety of Currently Available Devices

“…The mean patient age was 67.4 (range 61.4-72.8) yr. The Piranha morcellator was used in 13 studies for treatment of 2644 patients [23,[25][26][27][28][29][30][31][36][37][38][39][40], while VersaCut was utilized in 17 studies in treating 2907 patients [16][17][18][19][20][21][22]24,[33][34][35][36][37][38][39][40][41]. The DrillCut device was investigated in two studies for treatment of 101 patients [32,41].…”

“…Six studies were of comparative nature, with comparison of Piranha versus VersaCut in five [36][37][38][39][40] and of DrillCut versus VersaCut in one [41]. The remaining 20 studies investigated a single morcellator and partly included subgroups to compare, for example, different blade types [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. Table 1 presents a summary of patient demographics, baseline characteristics, and perioperative outcomes.…”

Learning curve of ThuLEP (Thulium laser enucleation of the prostate): Single‐centre experience on initial consecutive 60 patients

“…As shown in Figure 1, there were insignificant increases in both enucleation and morcellation times in Group 2 compared with Group 1. Morcellation time and efficiency may also depend on the heterogeneity of the prostate adenoma densities (Kaya et al, 2019). We believe that the increase in the duration of the procedure in Group 2 compared with Group 1 could be due to the careful performance of enucleation and morcellation in order to protect the prostatic capsule.…”
