Retzius sparing robot-assisted radical prostatectomy: optimizing functional results.

The aim of this study is to critically evaluate the existing body of evidence regarding the efficacy of Retzius-sparing radical prostatectomy (RS-RARP) in achieving improved functional outcomes. Moreover, we explored possible strategies to further optimize functional outcomes.

Following PRISMA guidelines, a systematic review (PROSPERO ID CRD42024539915) was performed on 9th September 2023 on PubMed, Scopus, and Web of Science. Only original articles in the English language reporting functional outcomes after RS-RARP were included.

Overall, the search string yielded 99 results on PubMed, 122 on Scopus, and 120 on Web Of Science. After duplicate exclusion, initial screening and eligibility evaluation, a total of 47 studies were included in the qualitative analysis, corresponding to a cohort of 13.196 patients. All studies reported continence recovery. RS-RARP appeared to achieve better and faster continence recovery compared to S-RARP. However, it should be noted that continence definition was heterogeneous and not based on validated condition-specific questionnaires. Seven (15%) studies provided for any sort of rehabilitation for urinary incontinence after RS-RARP. 22 studies analyzed potency recovery rates, showing no difference between RS-RARP and S-RARP. The evaluation of this outcome poses a great challenge due to the lack of standardized assessment tools and reporting methods. Only two studies reported on the consistent use of post-operative PDE5i as penile rehabilitation.

The current review highlights the satisfactory functional results of Retzius-sparing robot assisted radical prostatectomy, which holds true irrespective of disease stage and prostate volume, with promising results even in patients previously treated for BPH or in the salvage setting. How can we optimize those results? The answer does not probably lie in further refinement of the surgical technique, but in giving greater attention to patient counselling and rehabilitation strategies in order to minimize regret and maximize satisfaction.
