Dissemination of robotic surgical technology for robot-assisted laparoscopic prostatectomy (RALP) has yielded advancements including the Retzius-sparing (RS) approach and the single-port (SP) platform. The safety and feasibility of each individual advancement have been evaluated, yet there is a lack of literature comparing SP RS-RALP to conventional multi-port (MP) RS-RALP. All patients who underwent RS-RALP at our institution between January 2019 and February 2021 were retrospectively reviewed. Data regarding baseline patient and tumor characteristics, operative characteristics, and surgical outcomes were collected and analyzed using the Fisher's exact test and two-tailed unpaired t tests. 62 patients were evaluated: 31 received SP RS-RALP and 31 received MP RS-RALP. Differences in patient age, BMI, and initial PSA were not observed. Lower median lymph node yield (SP: 4 vs MP: 12, p < 0.01), lower estimated blood loss (SP: 111.2 vs. MP 157.8 mL, p < 0.01), shorter operative time (SP: 207.7 vs. MP: 255.9 min, p < 0.01) and decreased length of stay (SP: 0.39 vs. MP: 1.23 days, p < 0.01) were observed in the SP RS-RALP cohort. No differences in positive surgical margins, complications, or biochemical recurrence rates were observed. SP RS-RALP is non-inferior to MP RS-RALP in terms of both perioperative and early oncologic outcomes. Despite the small sample size, the SP platform is a safe and feasible option for RS-RALP and confers potential benefits in the form of shorter operative time and reduced length of stay.

Purpose: The standard discharge pathway following robotic-assisted laparoscopic prostatectomy (RALP) involves overnight hospital admission. Models for same-day discharge (SDD) have been explored for multiport RALP, however, less is known regarding SDD for single-port RALP, especially in terms of patient experience. Methods: Patient enrollment, based on preoperative determination of potential SDD eligibility, commenced March 2020 and ended March 2021. Day-of-surgery criteria were utilized to determine which enrolled patients underwent SDD. Differences in preoperative characteristics and perioperative outcomes between patients undergoing SDD and patients undergoing standard discharge were evaluated. A prospectively administered questionnaire was designed to characterize patient-centered factors informing SDD perception. Results: Fifteen patients underwent SDD and 36 underwent standard discharge. Overall mean ± SD age and BMI were 63.6 ± 7.0 years and 29.7 ± 4.4 kg/m2, respectively. Mean operative time was shorter in the SDD cohort than the standard discharge cohort (188 min vs 217 min, p = 0.011). A higher proportion of cases that underwent SDD were performed using the Retzius-sparing approach, 80% (12/15) vs 33% (12/36) in the standard discharge cohort (p = 0.005). Rates of 90 day complication (p = 0.343), 90 day readmission (p = 0.144), and 90 day emergency department visits (p = 0.343) rates were all not significantly different between cohorts. Of questionnaire respondents undergoing standard discharge, 32% (8/25) cited pain as a reason for not undergoing SDD. Conclusions: With comparable outcomes to the standard discharge pathway, SDD is safe and effective in single-port RALP. Post-operative pain and perceptions of distance are implicated as patient-centered barriers to SDD; proactive pain management and patient education strategies may facilitate SDD.
