Single-port Robotic Transvesical Partial Prostatectomy for Localized Prostate Cancer: Initial Series and Description of Technique.

Partial prostatectomy has been described as an alternative to focal therapy for the management of localized low- and intermediate-risk prostate cancer.

To describe early outcomes and technique for single-port (SP) transvesical partial prostatectomy.

A retrospective analysis was performed for nine patients with low-volume, localized, low- to intermediate-risk prostate cancer (Gleason ≤7) undergoing SP transvesical partial prostatectomy replicating the inclusion criteria for focal therapy by a single surgeon from November 2020 to March 2022.

The daVinci SP access port was inserted percutaneously into the bladder and pnuemovesicum was achieved. The camera, robotic instruments, assistant port, and flexible suction tubing were introduced through the access port. The Koelis transrectal ultrasound with preoperative prostate magnetic resonance imaging fusion was used for intraoperative guidance.

Demographic information, intraoperative variables, and postoperative outcomes were collected in an institutional review board-approved database, and a descriptive statistical analysis was performed.

All cases were completed without requiring extra ports or conversion. No intraoperative complications were noted, and all patients were discharged on the day of surgery. Pathology showed Gleason scores of 3 + 3 = 6 in one case, 3 + 4 = 7 in seven cases, and 4 + 3 = 7 in one case, all with negative intraoperative margin assessment. At 6 wk, the median prostate-specific antigen was 0.5 and the median Sexual Health Inventory for Men score was 17.5 from 23 preoperatively. All patients were continent at 6 wk. The limitations include a small number of patients, short follow-up, and single-surgeon experience.

We demonstrated the feasibility of the SP robotic transvesical partial prostatectomy. Early functional outcomes show impressive time to continence and erectile function. Continued follow-up will evaluate long-term oncologic outcomes.

We performed partial prostatectomies in selected patients as an alternative to focal therapy using a novel transvesical single-port approach. Our approach was safe and feasible, with fewer complications and promising initial return to continence and erectile function.
