Minimally-Invasive Radical Nephrectomy and Left-Sided Level II Caval Thrombectomy: A New Combined Technique.

OBJECTIVE: To present a combined multiport robotic and open approach for left radical nephrectomy and inferior vena cava thrombectomy in patients with a primary left renal mass and level II inferior vena cava (IVC) tumor thrombus. METHODS: A 69-year-old female was diagnosed with an 8.9cm left renal neoplasm with level II IVC thrombus. She was placed in the left-side-up flank position. The descending colon was mobilized and the left gonadal vein was identified. The left renal vein was identified and fully dissected. The left renal artery was dissected and stapled. The kidney was dissected and left detached with exception of the renal vein. The robot was undocked and the patient was positioned supine. Through a supra-umbilical midline incision, the ascending colon and duodenum were mobilized medially. The right renal vein and IVC were identified and dissected to the level of hepatic veins. The IVC was clamped using a Satinsky clamp. The right renal artery and vein remained patent during thrombectomy. The IVC was opened, the thrombus was evacuated, and IVC was closed. Clamps were removed and the kidney was removed. RESULTS: Operative time was 405 minutes. IVC clamp time was 14 minutes. Estimated blood loss was 500cc. Recovery was uncomplicated. Length of stay was 4 days. Pathology showed clear cell carcinoma with negative margins. CONCLUSION: IVC thrombectomy is challenging on left sided tumors. Combining a robotic and open technique together is feasible and allows a smaller supra-umbilical midline incision compared to standard open incision.

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

BACKGROUND: Partial prostatectomy has been described as an alternative to focal therapy for the management of localized low- and intermediate-risk prostate cancer. OBJECTIVE: To describe early outcomes and technique for single-port (SP) transvesical partial prostatectomy. DESIGN, SETTING, AND PARTICIPANTS: 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. SURGICAL PROCEDURE: 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. MEASUREMENTS: Demographic information, intraoperative variables, and postoperative outcomes were collected in an institutional review board-approved database, and a descriptive statistical analysis was performed. RESULTS AND LIMITATIONS: 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. CONCLUSIONS: 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. PATIENT SUMMARY: 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.

Da Vinci SP radical prostatectomy: a multicentric collaboration and step-by-step techniques

ABSTRACT Introduction Several techniques of robotic-assisted radical prostatectomy (RARP) using the da Vinci SP (SP) have been described since its clearance by the FDA (Food and Drug Administration) in 2018 ( 1 , 2 ). Even with the expanding literature about this robot, the SP technology has been restricted to a few centers in the US and Asia due to the recent release of this robot in the marked.3 In this scenario, we provided, in this video compilation, a consensus of SP referral centers describing the current approaches and techniques of da Vinci SP Radical prostatectomy (SP-RARP). Surgical Technique We have illustrated five different techniques, including transperitoneal, extraperitoneal, Retzius-sparing, transvesical, and transperineal ( 4 - 6 ). Each surgery demonstrated crucial steps from the trocar placement until anastomosis. All approaches follow anatomic concepts and landmarks to minimize positive surgical margins, optimize oncological outcomes and promote optimal functional recovery. The trocar placement and the use of an assistant port were selected according to the operative technique of each institution. None of these surgeries had intra- or postoperative complications, and the pain management until discharge was controlled without using narcotics. All patients were discharged in less than 16 hours of surgery. Conclusion Robotic-assisted radical prostatectomy performed with the da Vinci SP is feasible and safe with optimal perioperative outcomes. Five different approaches were described in this video compilation, and we believe that the technical details provided by this multicentric collaboration are crucial for centers willing to initiate the SP approach to radical prostatectomy.

Contemporary techniques of da Vinci SP radical prostatectomy: multicentric collaboration and expert opinion

ABSTRACT Background The da Vinci SP robot consists of an innovative single port trocar that houses a flexible camera and three biarticulated arms, which minimizes the number of incisions to assess the surgical site, allowing a less invasive procedure. However, due to its recent release in the market, the current literature reporting SP-RARP is still restricted to a few centers. In this scenario, after performing a literature search with all available techniques of SP-RARP, our objective is to report a multicentric opinion of referral centers on different techniques to approach SP-RARP. Results The SP literature is provided by only a few centers due to the limited number of this new console in the market. Five different approaches are available: transperitoneal, extraperitoneal, Retzius-Sparing, transperineal and transvesical. None of the current studies describe long-term functional or oncological outcomes. However, all approaches had satisfactory operative performance with minimum complication rates. Conclusions Several techniques of SP-RARP have been reported in the literature. We performed a multicentric collaboration describing and illustrating the most challenging steps of this surgery. We believe that the details provided in this article are useful teaching material for new centers willing to adopt the SP technology.

Single-Port Donor Nephrectomy via Modified Pfannenstiel Incision: Initial Preclinical Experience in a Cadaveric Model and Description of Technique.

Objective: To describe the surgical technique for the single-port (SP) transperitoneal donor nephrectomy (DN) through a modified Pfannenstiel incision using the Da Vinci SP® surgical system (Intuitive Surgical, Sunnyvale, CA) on a cadaver. Patients and Methods: In a male cadaver, the SP surgical system was used to perform transperitoneal DN. A 3-cm modified Pfannenstiel incision was made. Through the incision GelPOINT mini (Applied Medical, Rancho Santa Margarita, CA) was inserted. The floating docking technique was used. Through the gel port, the dedicated 25-mm multichannel port and a 12-mm assistant port were introduced. The surgical steps for DN were performed in the following order: (1) mobilization of the colon, (2) identification of psoas muscle, ureter, and the gonadal vein, (3) hilum dissection, (4) perirenal dissection, (5) stapling the renal artery and renal vein, and (6) removal of the kidney through the enlarged incision. Results: Transperitoneal SP DN was completed without any complications or capsulotomy. Additional ports were not needed. The total operative time was 63 minutes and 54 seconds. A good-quality kidney was harvested. Renal artery length was 4 cm. Conclusion: We demonstrated the feasibility of SP transperitoneal DN through modified Pfannenstiel incision, using the novel SP robotic platform. Further assessment is necessary in a clinical setting.

Single-port Mini-Pfannenstiel Robotic Pyeloplasty: Establishing a Non-narcotic Pathway Along With a Same-day Discharge Protocol.

OBJECTIVE: To analyze the feasibility of a same day discharge protocol following single-port (SP) robotic pyeloplasty. MATERIALS AND METHODS: From a single institution series, 23 patients (12 multi-port, 11 SP) who underwent primary robotic dismembered pyeloplasty between February 2018 and March 2021 were analyzed. The association between baseline and perioperative characteristics with functional outcome was analyzed using, chi-square, Fisher's exact, Mann Whitney U and t tests. RESULTS: All SP cases were completed using the mini Pfannenstiel incision without the need for conversion or additional ports. Baseline characteristics were comparable. No intraoperative complications were seen. Only 1 patient in the SP group had a Clavien II complication. All patients in the multi-port group had a drain placed, whereas drain was not placed in the SP group. Length of stay was shorter in the SP group (11.4 vs 42.6 hours, P <.001). Although visual analog pain score was comparable at discharge (P = .633), the SP group had lower opioid usage (morphine milligram equivalent) in the hospital (P <.001) and a lower rate of opioid prescription during discharge (18.2% vs 91.7% P <.001). At a median follow-up of 8 months, no patients had flank pain and all patients had good kidney drainage on follow-up images. CONCLUSION: Single-port robotic dismembered pyeloplasty through a mini-Pfannenstiel access allows a same-day discharge protocol with minimal opiate use.
