Robotic Prostatectomy for High-risk Prostate Cancer: Translating the Evidence into Lessons for Clinical Practice

Robotic radical prostatectomy in high-risk prostate cancer: current perspectives

Around 20%–30% of patients diagnosed with prostate cancer (PCa) still have high-risk PCa disease (HRPC) that requires aggressive treatment. Treatment of HRPC is controversial, and multimodality therapy combining surgery, radiation therapy, and androgen deprivation therapy have been suggested. There has been a trend toward performing radical prostatectomy (RP) in HRPC and currently, robot-assisted laparoscopic RP (RARP) has become the most common approach. Number of publications related to robotic surgery in HRPC is limited in the literature. Tissue and Tumor characteristics might be different in HRPC patients compared to low-risk group and increased surgical experience for RARP is needed. Due to the current literature, RARP seems to have similar oncologic outcomes including surgical margin positivity, biochemical recurrence and recurrence-free survival rates, additional cancer therapy needs and lymph node (LN) yields with similar complication rates compared to open surgery in HRPC. In addition, decreased blood loss, lower rates of blood transfusion and shorter duration of hospital stay seem to be the advantages of robotic surgery in this particular patient group. RARP in HRPC patients seems to be safe and technically feasible with good intermediate-term oncologic results, acceptable morbidities, excellent short-term surgical and pathological outcomes and satisfactory functional results.

A novel surgical technique for preserving the bladder neck during robot-assisted laparoscopic radical prostatectomy: preliminary results

PURPOSE

To describe our new surgical technique for preserving the bladder neck during robot-assisted laparoscopic prostatectomy (RALP) and to present the anatomy between the bladder neck and prostate.

METHODS

Between December 2012 and May 2014, 52 RALPs were performed at our institute. Demographic, perioperative, and postoperative data were recorded. Quality of life (QoL) scores were assessed before RALP, after urethral catheter removal, and at the first month after RALP. Fatty connective tissue between bladder neck and prostate was introduced, and circular muscle fibers of the internal sphincter were seen in all patients. Complications were classified according to the Clavien-Dindo classification. Statistical analyses were performed.

RESULTS

Mean follow-up was 9.6±5.2 months; mean age was 61.1±6.5 years. Our novel surgical technique for preserving the bladder neck was performed in 52 patients, and they were continent after catheter removal; mean duration of the catheter was 9.4±1.4 days. There was a significant difference in QoL before RALP and after catheter removal, however, but there was no statistical difference between before and 1 month after RALP (respectively; P<0.001, P=0.5). Furthermore, there was no complication related to the bladder neck such as bladder neck stricture, acute/chronic urinary retention, as well as no Clavien III, IV, and V complications. In addition, conventional laparoscopy and/or open surgery was not needed in any of the RALP cases.

CONCLUSION

Our novel technique provided very early continence at the time of catheter removal after RALP within short-term follow-up. This can help early recovery and develop QoL scores after RALP.
