Assessment of routine same-day discharge surgery for robot-assisted radical prostatectomy.

INTRODUCTION: It is important for robotic surgery to be cost-effective, especially by reducing the length of stay (LOS). Therefore, we developed a protocol for day-case robot-assisted radical prostatectomy (RARP). This study aimed to validate this as a safe practice of care and to assess the potential benefits to the hospital and patient. METHODS: In this single-centre study, all patients booked for RARP between April 2022 and October 2022 were screened for suitability for day case. All tumour types were included. Exclusion criteria were a history of complex abdominal surgeries, salvage prostatectomy, body mass index (BMI) > 35 and patient living alone or > 150 km away from the hospital. All day-case RARPs were performed as a morning case with a protocol for review throughout the day with evening discharge if mobilising independently and eating/drinking well. The primary outcome of the study was success rate of discharge home on day of surgery (DOS) with secondary outcomes of readmissions and complications. A patient questionnaire was completed at home including both visual analogue scale (VAS) for pain and satisfaction rating. RESULTS: Forty-five patients underwent day-case RARP over a 6-month period with minimum of 30 days of follow-up. 41/45 (91%) had successful DOS discharge home. The four admissions overnight were due to dizziness, low oxygen saturation, intraoperative complications and a diagnosis of COVID-19. There were no readmissions and no 30-day complications. The most common issues at home were catheter discomfort and constipation with low mean VAS pain score and low nausea reported. The overall patient satisfaction rating was very high at 4.8/5, and 97% said they would recommend to a family member. The cost saving for the hospital was 400 pounds per patient. CONCLUSION: Day-case procedure is a viable, safe and efficient pathway for appropriately selected and counselled patients undergoing RARP.

Functional and oncological outcomes of robot-assisted radical prostatectomy in obese men: a matched-pair analysis.

Robot-assisted radical prostatectomy (RARP) in men with body mass index (BMI) ≥ 35 kg/m2 is considered technically challenging. We conducted a retrospective matched-pair analysis to compare the oncological and functional outcomes of RARP in men with BMI ≥ 35 kg/m2. We interrogated our prospectively maintained RARP database and identified 1273 men who underwent RARP from January 2018 till June 2021. Among them, 43 had BMI ≥ 35 kg/m2, and 1230 had BMI < 35 kg/m2. A 1:1 genetic matching was performed between these two groups for PSA, Gleason grades, clinical stage, D'Amico risk stratification, and nerve-spare extent. Continence rates and biochemical rates on 1-year follow-up were analysed. We performed statistical analysis using SPSS, and Paired tests were done using Wilcoxon sign rank-sum test. p < 0.05 was considered statistically significant. The two groups were comparable in almost all parameters except for age. Console time (p = 0.20) and estimated blood loss (p > 0.90) were not significantly different. There was no blood transfusion, open conversion or (Clavien-Dindo grade ≥ 3) intra/postoperative complication in either of the two groups. The two groups did not have any difference in biochemical recurrence rates (BCR) on 1-year follow-up (p > 0.90). Men with BMI ≥ 35 achieved continence rates equivalent to men with BMI < 35 within 1 year. On logistic regression analysis, age (p < 0.001) and extent of nerve sparing (p = 0.026) emerged as significant factors influencing continence recovery. RARP is safe in men with BMI ≥ 35 kg/m2. The 1-year continence and oncological outcomes are similar to matched men with BMI < 35 kg/m2 undergoing RARP.
