Introduction: Robot-assisted radical prostatectomy (RARP) provides much quicker recovery for men than open prostatectomy. In most centers, discharge is planned the morning after operation. However, after several years, we observed that no routine intervention was required for a majority of men over the first evening. Here, we detail our institution’s outcomes for multiport RARP (MP-RARP) with same-day discharge (SDD). Methods: After excluding patients with single-port RARP ( n = 25) and overnight stays ( n = 30), data from 224 patients ( n = 224/279, 88.2%) who underwent MP-RARP from May 2021 to September 2023 were collected. All patients were placed on an Enhanced Recovery After Surgery protocol and were given instructions regarding SDD. Patients were considered as SDD if they were discharged on the day of operation. Data regarding messages and phone calls to health care providers, urology clinic, and emergency department visits were recorded for analysis in the week postoperation. Results: The mean (±standard deviation [SD]) operative time was 142.5 ± 25.2 minutes, with a mean (±SD) console time of 95.1 ± 25.6 minutes. The median (interquartile range [IQR]) estimated blood loss was 50 (50–100) mL, and the mean (±SD) length of hospitalization was 163.2 ± 64.6 minutes. No intraoperative complications occurred in this cohort. The median (IQR) patient-reported pain score at 1 hour after operation was 3.5 (0–7), compared with 2 (0–4) at discharge. Of the 145 (64.7%) patients who reported their postoperative pain management, only 50 (34.4%) endorsed using opioids, and of those, 8 (16%) were known chronic opioid users. In the week after operation, 14 (6.3%) patients had unplanned visits to the health care facility. Additionally, 56 (25%) of patients contacted the clinic regarding the postoperative course during the same time frame. Conclusions: SDD after RARP is predictable and safe. SDD helps reduce the costs associated with inpatient stays without compromising surgical outcomes for patients.

Background & Objectives: Patients with bladder outlet obstruction (BOO) due to massive prostate enlargement have several surgical treatment options, such as robot-assisted simple prostatectomy (RASP) and holmium laser enucleation of the prostate (HoLEP). Postoperative outcomes may differ between those undergoing RASP and HoLEP. RASP has been associated with a lower incidence of transient stress urinary incontinence (SUI), while HoLEP allows for shorter catheterization times. Here, we report on our experience with both surgical modalities. Methods: Data were collected from prospectively maintained databases for 37 RASP patients and 181 HoLEP patients treated from July 2021 to November 2023. To control for selection bias, propensity score matching (PSM) was utilized based on age and prostate size. We compared patients’ preoperative, perioperative, and postoperative outcomes both before and after applying PSM. Results: Before the PSM, the median prostate size was significantly lower in the HoLEP group (p < 0.001). The HoLEP group also had significantly shorter operative times (p ≤ 0.001) and lower weights of resected adenoma (p ≤ 0.001). After the PSM of 31 RASP and 31 HoLEP patients, all baseline patient characteristics were comparable. No significant differences were observed in operation time (p = 0.140) or in the weight of resected adenoma (p = 0.394) between the modalities. The median (IQR) length of catheterization was significantly shorter in the HoLEP group (1 [1–4] days) compared to the RASP group (7 [7–8] days), in both pre- and post-matching analyses (p ≤ 0.001 for both), reflecting the standard of practice. In contrast, in both pre- and post-PSM analyses, the average hospital stay was significantly shorter in the RASP cohort, as same-day discharge is standard in our center, whereas the HoLEP cohort required overnight stays due to routine continuous bladder irrigation before discharge (p < 0.001 for all). Notably, the SUI rates and American Urological Association (AUA) symptom scores were comparable at 3 months within both matched and unmatched cohorts (pre-PSM: p = 0.668, p = 0.083; post-PSM: p = 1, p = 0.152, respectively). Conclusions: Our comparative analysis indicates that both RASP and HoLEP yield similar outcomes, including SUI rates, at 3 months. While HoLEP provided shorter durations of postoperative catheterization, RASP offered shorter hospital stays.
