Abstract
Purpose: To investigate changes in nocturia and predictive factors for improvement after photoselective vaporization of the prostate (PVP) for patients with benign prostatic hyperplasia (BPH).
Materials and Methods: A total of 103 patients who complained of nocturia of ≥2 times per night on baseline frequency-volume chart (FVC) and who underwent PVP were included in this retrospective study. All patients underwent a preoperative evaluation for BPH including multichannel video urodynamics. The efficacy of the PVP was evaluated at 1, 3, 6, and 12 months postoperatively by use of the International Prostate Symptom Score (IPSS) and FVC. Subjective and objective improvement of nocturia were defined as a reduction of ≥50% in nocturnal frequency compared with baseline on the IPSS and FVC, respectively.
Results: As shown by the IPSS and FVC, nocturia was significantly reduced starting from 1 month after PVP. The percentage of patients with improvement in nocturia was 20.0%, 20.7%, 36.2%, and 27.9% on the IPSS, and 30.1%, 48.6%, 52.2%, and 54.5% on the FVC at 1, 3, 6, and 12 months after PVP, respectively. None of the baseline parameters, including the presence or absence of nocturnal polyuria (NPU), reduced nocturnal bladder capacity (NBC), and detrusor overactivity (DO), were associated with improvement of nocturia.
Conclusions: Nocturnal frequency was significantly reduced from the early postoperative period after PVP. Improvement in nocturia after PVP was not affected by baseline nocturnal frequency, the presence or absence of preoperative NPU, or reduced NBC or DO on baseline urodynamics.
