Novel composite BPH3 trifecta for robotic assisted simple prostatectomy (RASP) versus BPH6: A multicenter outcomes comparison

Abstract

Objectives: To assess disobstructive proficiency of BPH3 trifecta in RASP according to different techniques. Methods: Baseline prostate volume (PV), uroflowmetry parameters and Validated questionnaires: IIEF, Incontinence severity index score (ISI), International prostatic symptoms score (IPSS), MSHQ, Quality of recovery (QOR), were recorded preoperatively and 12 months postoperatively. RASP was conducted using both the urethra-sparing (Madigan) technique and a non-urethral-sparing transvesical (Freyer) approach. Two groups were evaluated for achievement rates in terms of BPH-3 and BPH-6. BPH-3 was defined by a combination of: a reduction of ⩾30% in IPSS compared to baseline, ISI score ⩽ 4, and absence of complications beyond Clavien grade 1. Results: About 158 patients underwent RASP, with 93 undergoing the Madigan procedure and 65 the Freyer approach. Patients in the Madigan group were younger, with lower PV, baseline IPSS score, overactive symptoms (ISI score), but higher MSHQ and IIEF score, when compared to the Freyer population (all p < 0.02). At 12-month follow-up, patients who underwent the Madigan procedure reported shorter bladder irrigation time and time to catheter removal (both p < 0.001). As expected, Madigan patients also demonstrated superior postoperative IIEF and MSHQ scores (all p < 0.001). Postoperative complication incidence was higher in the Madigan cohort, mainly due to UTI ( p < 0.001). Although there were no differences in postoperative IPSS and Q-max between groups, the Madigan cohort presented with higher post void residue ( p < 0.001). BPH6 achievement was higher in the Madigan cohort (48% vs 28%) ( p < 0.001), while no difference was observed in BPH3 achievement rate. Conclusion: The BPH3 composite trifecta appears to be more suitable than BPH6 in assessing the proficiency in disobstructive symptoms relief after RASP.
