[Evaluation of postoperative symptoms after Greenlight™ photovaporization of the prostate through a dedicated questionnaire]

To evaluate postoperative symptoms after Greenlight™ photovaporisation of the prostate (PVP), through a dedicated questionnaire.A retrospective study has been conducted between 2008 and 2014. The questionnaire had 5 sections about pain while voiding, hematuria, urgency, incontinence and urinary stream, and was filled at one-month postoperative. The main outcome criterion was pain while voiding. Descriptive statistical analyses were done to identify predictive factors for pain while voiding.Out of 169 patients, 22% had no pain while voiding, 37% had moderate pain, 30% acceptable pain and 11% intense pain. Patients with pain were significantly older, (P=0.012), had more urgency (P=0.01) and more often hematuria (P=0.0001). Only 7% of patients had no symptoms of urgency, and urgency was painful or bothering in 57% of cases. Hematuria was frequent, with clots in 21% of cases. Ninety three percent felt improvement of urinary stream.Systematic evaluation of symptoms through a dedicated questionnaire one month after PVP has shown that 41% of patients felt pain while voiding, 57% had urgency and 39% significant hematuria. These results should encourage a more accurate patient information and further studies to better understand postoperative healing after PVP.
