Can preoperative detrusor underactivity influence surgical outcomes of 120 W HPS vaporization of the prostate (PVP) or holmium laser enucleation of the prostate (HoLEP)? A serial 3-year follow-up study.

To determine the influence of preoperative detrusor underactivity (DU) on serial long-term outcomes of HPS/PVP or HoLEP for LUTS/BPH, and to compare the influence between the two surgeries.

A total of 382 men, who underwent 120W-HPS/PVP or HoLEP for LUTS/BPH and for whom 36-month follow-up data were available, were classified into four groups: HPS with DU (n = 145), HPS without DU (n = 44), HoLEP with DU (n = 105), and HoLEP without DU (n = 88). DU was defined as bladder contractility index of <100. Surgical outcomes were assessed at postoperative 6, 12, 24, and 36 months using IPSS, uroflowmetry, and serum PSA.

All four groups maintained improvements in voiding symptom score (VSS), storage symptom score, total-IPSS, QOL index, maximum flow rate (Qmax), post-void residual urine volume (PVR), and bladder voiding efficiency (BVE) compared with baseline up to 3 years postoperatively. There were no significant differences in improvements of postoperative IPSS parameters including QOL index between men with and without DU throughout the follow-up period after HPS or HoLEP. In men with DU, there were no significant differences in improvements of postoperative QOL index, Qmax, PVR, or BVE between HPS and HoLEP groups throughout the follow-up period, except for VSS and total IPSS. Serum PSA reductions after HoLEP were greater than after PVP.

Improvements in LUTS, Qmax, and BVE can maintain up to 3 years after HPS or HoLEP for LUTS/BPH, irrespective of the presence or absence of preoperative DU. Although HoLEP may provide more durable improvement of VS in men with DU than HPS, there seems to be no difference in improvement of QOL or Qmax or BVE between HPS and HoLEP.
