Purpose:
To evaluate the efficacy of holmium laser enucleation of the prostate (HoLEP) in patients with a small prostate volume (≤30 mL).
Materials And Methods:
We retrospectively evaluated 1,135 patients who underwent HoLEP at two institutions between July 2007 and March 2020. Patients who were not evaluated for the International Prostate Symptom Score (IPSS) before or after HoLEP were excluded. We divided patients into two groups according to estimated prostate volume (ePV): ≤30 (n=198) and >30 mL (n=539). The patient characteristics, IPSS, peak urinary flow rate (Qmax), postvoid residual urine volume (PVR), and other data were compared before and after surgery in each group and between the two groups. Multivariate analysis was performed to identify the factors associated with the efficacy of HoLEP in the group with ePV ≤30 mL.
Results:
A total of 737 patients were included in this retrospective study. ePV (23.4 mL vs. 50 mL; p<0.001) and PVR differed significantly between the two groups. The IPSS, IPSS-quality of life, PVR, and Qmax significantly improved after HoLEP in both groups. Improvements in the IPSS, IPSS-quality of life, Qmax, and PVR were greater in the >30 mL group (p<0.001), whereas operation time and morcellation time were significantly shorter in the ≤30 mL group. In the multivariate analysis, age <70 years was independently associated with improvement by HoLEP.
Conclusions:
HoLEP is an effective treatment for patients with a small prostate, even though the extent of improvement after HoLEP was greater in those with a larger prostate.
