To evaluate the efficiency and efficacy of HoLEP, and methods of tissue retrieval, in patients with prostate volume (PV) ≥ 200 cc (Group 1) and to compare these to patients with PV 80-199 cc (Group 2).
A database of all cases performed under the care of two surgeons at a tertiary HoLEP centre was reviewed.
157 patients with PV ≥ 200 cc were compared to 157 of the most recent consecutive cases with PV 80-199 cc. Median (IQR) enucleation efficiency was greater in Group 1 [2.8 g/min (2.2-3.5)] than Group 2 [2.1 g/min (1.6-2.5), p < 0.001]. Morcellation efficiency did not differ significantly. Cystotomy was required for tissue retrieval in Group 1 only (5.7%). Decrease in serum haemoglobin (Hb) was greater in Group 1 (19 g/l (30-8) vs 12 (18-3.5), p < 0.001) with a transfusion rate of 4.5% vs 1.3%, respectively (p = 0.104). Length of stay was longer in Group 1 than Group 2 (1 day (1-2) vs 1 (1-1), p < 0.001). There were no significant differences between groups in: time to and success of first trial without catheter, pre- and post-operative IPSS, Qmax and PVR, and 3 month catheter-free and urinary incontinence rates.
HoLEP outcomes are largely PV-independent even when PV is ≥ 200 cc, although length of stay and reduction in Hb are greater in this group. Alternatives to pure morcellation, such as cystotomy and resection of nodules, are more likely to be necessary with PV ≥ 200 cc.
