Objectives: The aim of the present study was to establish the safety and efficacy profile of transurethral resection in saline (TURis) bipolar vaporization of the prostate relative to monopolar transurethral resection of prostate (TURP) and to test the hospital stay efficiency after TURis vaporization.
Materials and methods: in this multicenter, double-blinded, prospective, randomized controlled trial, men aged 50-75 years old were randomized into two arms: TURis bipolar vaporization and monopolar TURP. Intraoperative details, perioperative parameters, and postoperative functional outcomes were assessed after intervention. Follow-up with symptom score assessment, prostate volume measurement, and uroflowmetry were performed at 3 and 6 months.
Results: Eighty-four patients (mean age, 65.0 ± 5.6 years) were randomized into each study arm. TURis bipolar vaporization had a longer operative time than monopolar TURP (51.6 ± 24.5 vs 38.5 ± 20.3 min, P < 0.001). Postoperatively, the TURis group had a shorter catheter time (33.6 ± 23.7 vs 40.8 ± 29.4 h, P = 0.013) and a shorter length of hospital stay (43.14 ± 18.79 vs 52.33 ± 30.58 h, P = 0.013). The postoperative dysuria score was higher in the TURis vaporization arm. There was no statistically significant difference between the two arms in terms of hemoglobin change and postoperative complication. No significant difference was observed in quality of life score at 3 and 6 months.
Conclusions: TURis bipolar vaporization of the prostate is a safe and comparable alternative to monopolar TURP. It leads to a reduction in both catheter time and length of hospital stay.
