Objective: To compare the outcomes of robotic-assisted laparoscopic prostatectomy (RALP) using a dual versus single-console system in a resident training program using intraoperative, perioperative and postoperative measures. Methods: Patients with PCa who underwent RALP prior to and after implementing a dual-console system at an academic institution were reviewed from 2006-2012. All surgeries were performed by a single-faculty surgeon well after the learning curve was established. In all cases, chief residents participated in the surgery and performed progressively more portions. Demographic, intraoperative and pathologic parameters were obtained. Continence and erectile function were assessed at 6 and 12 months. Postoperative complications were graded using the Clavien-Dindo classification. Predictors of outcomes on univariate analysis were included in multivariate logistic or linear models. Results: Of 381 patients, 185 and 196 underwent single- or dual-console RALP, respectively. There was a significant decrease in mean operative time using the dual-console system (222 vs. 171 min, p < 0.0001) as well as in the incidence of intraoperative complications (8.65 vs. 1.53 %, p < 0.0001) and postoperative complications (14.1 vs. 6.63 %, p = 0.03.) Complications of Clavien grade ≥3a occurred more frequently with a single-console system (7 vs. 1 %, p = 0.003.) Differences persisted when controlling for potential confounders by multivariate regression. Postoperative measures of continence, erectile function and the rate of biochemical recurrence were similar between cohorts. Conclusions: When training resident surgeons to perform RALP, a dual-console system may improve intraoperative and perioperative outcomes. The dual-console may represent a safer, more efficient modality for robotic surgical education as compared to a single-console system. [ABSTRACT FROM AUTHOR]

There has been an increase in the number of urologic procedures performed robotically assisted; this is the case for radical prostatectomy. Currently, in the USA, 67% of prostatectomies are performed robotically assisted. With this increase in robotic urologic surgery it is clear that there are more surgeons in their learning curve, where most of the complications occur. Among the complications that can occur are vascular injuries. These can occur in the initial stages of surgery, such as in accessing the abdominal cavity, as well as in the intraoperative or postoperative setting. We present the most common vascular injuries in robot-assisted radical prostatectomy, as well as their management and prevention. We believe that it is of vital importance to be able to recognize these injuries so that they can be prevented. [ABSTRACT FROM PUBLISHER]

Objective: The objective of this study was to compare robotic-prostatectomy plus adjuvant radiation therapy (RPRAT) versus primary RT for high-risk prostate cancer (HRPCa). Materials and Methods: A retrospective chart review was performed for the HRPCa patients treated in our institution between 2000 and 2010. One hundred and twenty-three patients with high-risk disease were identified. The Chi-square test and Fisher's exact test were used to compare local control and distant failure rates between the two treatment modalities. For prostate-specific antigen comparisons between groups, Wilcoxon rank-sum test was used. Results: The median follow-up was 49 months (range: 3-138 months). Local control, biochemical recurrence rate, distant metastasis, toxicity, and disease-free survival were similar in the two groups. Conclusions: Primary RT is an excellent treatment option in patients with HRPCa, is equally effective and less expensive treatment compared with RPRAT. A prospective randomized study is required to guide treatment for patients with HRPCa. [ABSTRACT FROM AUTHOR]

Objective. Robotic prostatectomy has rapidly disseminated over the past decade. How managed care, thought by many to be a barrier to new technology, influences the dissemination of robotics is unknown. We sought to better understand the relationship between a market’s managed-care penetration and the dissemination of robotic prostatectomy. Methods. We used SEER-Medicare data from 2003 through 2007 to identify men ≥66 years of age treated with radical prostatectomy for prostate cancer. We categorized Health Service Areas (HSAs) according to the degree of managed-care penetration (ie, low vs high). We assessed adoption of robotic prostatectomy and utilization among adopting HSAs using Cox proportional-hazards and Poisson regression models, respectively. Results. Compared with markets with little managed care, highly penetrated markets had more racial diversity (24% vs 15% nonwhite, P < .01), higher population densities (1987 vs 422 people/square mile, P < .01), and higher median incomes ($49 374 vs $36 236, P < .01). Robotic prostatectomy adoption and utilization increased over time in both HSA categories. Compared with low managed-care markets, those with high managed care adopted robotic prostatectomy more rapidly (eg, probability 0.37 [low] vs 0.52 [high] in 2007; P < .01). However, the postadoption utilization of robotic prostatectomy was constrained in these highly penetrated markets (eg, probability 0.66 [low] vs 0.52 [high] in 2007; P < .01). Conclusions. High managed-care penetration was associated with more rapid robotic prostatectomy adoption. However, once adopted, utilization increased more slowly in these markets. Understanding this paradox is important as more technologies are unveiled in an increasingly cost-conscious health care environment. [ABSTRACT FROM PUBLISHER]

The development of a lymphocele after pelvic surgery is a well-documented complication, especially where pelvic lymph node dissection (PLND) is part of the operation. However, not all lymphoceles are symptomatic and require treatment. Most lymphoceles spontaneously resolve, and even lymphoceles that become symptomatic may resolve without any intervention. Robotic assisted radical prostatectomy (RARP) is a common operation in urology where PLND is likely to be performed in intermediate and high-risk prostate cancer patients. The rationale for performing a PLND in prostate cancer is for accurate staging and potential therapeutic benefits. However, due to potential intraoperative and postoperative complications there is still a debate regarding the value of PLND in prostate cancer. In this review, we will discuss the potential risk factors to be aware of in pelvic surgery in order to minimize the formation of a lymphocele, along with the management for clinically significant lymphoceles.

Vesico-urethral anastomosis (VUA) is a technically challenging step in robotic-assisted laparoscopic prostatectomy (RALP) in obese individuals. We describe technical modifications to facilitate VUA encountered in obese individuals and in patients with a narrow pelvis. A Pubmed literature search was performed between 2000 and 2012 to review all articles related to RALP, obesity and VUA for evaluation of technique, complications and outcomes of VUA in obese individuals. In addition to the technical modifications described in the literature, we describe our own experience to encounter the technical challenges induced by obesity and narrow pelvis. In obese patients, technical modifications like use of air seal trocar technology, steep Trendlenburg positioning, bariatric trocars, alterations in trocar placement, barbed suture and use of modified posterior reconstruction facilitate VUA in robotic-assisted radical prostatectomy. The dexterity of the robot and the technical modifications help to perform the VUA in challenging patients with lesser difficulty. The experience of the surgeon is a critical factor in outcomes in these technically challenging patients, and obese individuals are best avoided during the initial phase of the learning curve.

Introduction: Urinary continence is an important outcome parameter after robot assisted radical prostatectomy (RARP). We evaluated the continence outcomes following RARP using a double-layered urethrovesical reconstruction. Materials and Methods: One hundred fifty consecutive patients undergoing RARP and double-layered urethrovesical reconstruction were prospectively studied for preoperative, intraoperative and post operative parameters. Key points followed during surgery were: Minimal dissection of sphincteric complex, preservation of puboprostatic ligament, selective ligation of deep venous complex and both posterior and anterior reconstruction using the Von Velthoven stitch. Intraoperative bladder fill test was done at the end of anastomosis to rule out urine leak. Check cystogram was done prior to catheter removal in the outpatient department. Patients were subsequently followed at regular intervals regarding the status of urinary continence. All patients irrespective of adjuvant therapy were included in the analysis. Results: The mean age was 64 years (standard deviation ± 6.88), and mean serum PSA was 20.2 ng/ml. The mean BMI was 25.6 (SD: ±3.84). The mean prostate weight was 44.09 gm (range 18-103 gm, SD: ±15.59). Median days to catheter removal after surgery was 7 (range 4-14 days) days. Cystographically determined urinary leaks were seen in two patients. Urine leak was managed by delaying catheter removal for 1 week. Minimum 6 month follow up was available in 126 patients. 'No pad' status at 1 week, 1 month, 3 months, 6 months and 1 year was 15.1%, 54.9%, 78%, 90.5% and 94.1%, respectively. Conclusion: Excellent continence outcomes are observed in patients undergoing double-layered urethrovesical reconstruction. [ABSTRACT FROM AUTHOR]

Background: The benefit of intraoperative neurovascular structure–adjacent frozen section examination (NeuroSAFE) of the prostate was demonstrated in open radical prostatectomy. In da Vinci robot-assisted prostatectomy (DVP), this approach is often avoided due to suspected difficulties in harvesting the prostate, loss in pneumoperitoneum, increased blood loss, and prolonged operating room (OR) time. Objective: To provide a detailed description of the technique, feasibility, and impact of the NeuroSAFE technique on OR time, blood loss, frequency of nerve sparing (NS), and positive surgical margins (PSMs) in DVP. Design, setting, and participants: We analyzed 1570 consecutive patients undergoing DVP from 2004 to 2012. NeuroSAFE was performed in 1178 patients. Surgical procedure: The prostate was intraoperatively harvested via an extension of the camera trocar incision without undocking the robotic arms. Blood spillage from the dorsal vein complex due to the loss of pneumoperitoneum was avoided by upward traction on the transurethral catheter. After prostate removal, pneumoperitoneum was reestablished by closing the extended incision with running sutures and repositioning the optical trocar. The NeuroSAFE procedure consisted of intraoperative bilateral frozen sections covering the entire neurovascular bundles adjacent prostate surface. Outcome measurements and statistical analysis: We compared OR time, blood loss, NS frequency, and PSMs in non-NeuroSAFE versus NeuroSAFE DVP. Results and limitations: There was no significant difference in blood loss (253.5±204.4ml vs 265.8±246.7ml; p =0.49) and OR time (220min ± 51 vs 224min ± 64; p =0.22). No complications associated with specimen harvesting occurred. NS rate increased significantly with versus without NeuroSAFE (overall 97% vs 81%; pT2 99% vs 90%, pT3a 94% vs 74%, pT3b 91% vs 30). PSM rate dropped significantly with NeuroSAFE (overall 16% vs 24%; pT2 8% vs 15%, pT3a 22% vs 39%, pT3b 49% vs 67%; all p <0.05). Conclusions: We demonstrate a time-efficient and safe adaption of the NeuroSAFE technique to DVP. Patient summary: We describe a feasible and secure adaption of the neurovascular structure–adjacent frozen section examination (NeuroSAFE) procedure for da Vinci robot-assisted prostatectomy. We showed that there was no increased blood loss and operating room time. We maximized the nerve-sparing frequency and could reduce positive surgical margins even in non–organ-confined tumors.

Background During 2008, the Royal Brisbane and Women's Hospital became the first public hospital in Australia to have a da Vinci Surgical Robot purchased by government funding. The cost of performing robotic surgery in the public sector is a contentious issue. This study is a single centre, cost analysis comparing open radical prostatectomy ( RRP) and robotic-assisted radical prostatectomy ( RALP) based on the newly introduced pure case-mix funding model. Methods A retrospective chart review was performed for the first 100 RALPs and the previous 100 RRPs. Estimates of tangible costing and funding were generated for each admission and readmission, using the Royal Brisbane Hospital Transition II database, based on pure case-mix funding. Results The average cost for admission for RRP was A$13 605, compared to A$17 582 for the RALP. The average funding received for a RRP was A$11 781 compared to A$5496 for a RALP based on the newly introduced case-mix model. The average length of stay for RRP was 4.4 days (2-14) and for RALP, 1.2 days (1-4). The total cost of readmissions for RRP patients was A$70 487, compared to that of the RALP patients, A$7160. These were funded at A$55 639 and A$7624, respectively. Conclusions RALP has shown a significant advantage with respect to length of stay and readmission rate. Based on the case-mix funding model RALP is poorly funded compared to its open equivalent. Queensland Health needs to plan on how robotic surgery is implemented and assess whether this technology is truly affordable in the public sector. [ABSTRACT FROM AUTHOR]

Purpose: Positive surgical margins (PSMs) may reflect incomplete surgical resection, while extraprostatic extension (EPE) could suggest that complete tumor resection is more difficult. This study evaluated cases with both EPE and PSMs in robotic-assisted radical prostatectomy (RARP) specimens to determine the respective locations of each. Methods: A single institutional retrospective review of RARP performed between 2007 and 2009 was conducted to identify cases with both EPE and PSM. Prostates were entirely submitted and processed in whole mount format. All locations of EPE and PSM were recorded as was the size of the largest focus of EPE and PSM. Results: About 8.5 % (112/1,315) of RARP had both EPE and PSM. Analysis of cases with concurrent EPE and PSM revealed that EPE occurred most commonly in the mid-gland, particularly in the posterolateral mid-prostate. In contrast, PSM was most frequent at the base (bladder neck), specifically the anterior base. 51.8 % of the cases had EPE and PSM in discordant locations, 19.6 % had EPE and PSM in the same location, and 28.6 % had areas of EPE and PSM both in the same location as well as in different locations. Cases with both concordant and discordant locations of EPE and PSM had significantly more high-risk features including higher tumor volume, more frequent positive nodes, and more frequent Gleason score ≥ 8 compared to concordant or discordant subgroups. Conclusion: PSMs frequently did not occur in the same location as EPE. A better understanding of where EPE and PSMs occur may help guide surgical technique to decrease residual tumor.

Of the morbidities associated with robotic prostatectomy, erectile dysfunction is one of the most significant in terms of patient's psychological and physical well-being. Many studies using current medications and devices for treating erectile dysfunction have been done to attempt to curtail the pathology associated with surgery by employing 'rehabilitation' strategies. The outcomes from these studies are mixed but overall have yet to show a clear benefit in implementing rehabilitation techniques. The results of these studies as well as the pathophysiology of erectile dysfunction after robotic prostatectomy are presented here. [ABSTRACT FROM AUTHOR]

Background: Pathological involvement of the seminal vesicle poses a treatment dilemma following robotic prostatectomy. Margin status plays an important role in deciding further management. A wide range of treatment options are available, including active monitoring, adjuvant radiotherapy, salvage radiotherapy, and occasionally androgen deprivation therapy. Patients undergoing postoperative radiotherapy tend to have higher risk of urinary and bowel morbidities. The recent RADICALS-RT concluded that adjuvant radiotherapy did not have any benefit compared with salvage radiotherapy. We aim to audit the incidence, margin status, and management of T3b cancer cases at our center., Materials and Methods: A retrospective analysis was conducted of all patients diagnosed with pathological T3b (pT3b) prostate cancer following robotic-assisted laparoscopic prostatectomy from January 2012 to July 2020. Preoperative parameters analyzed included prostate-specific antigen (PSA), T stage, and age. A chi-square test and 2-tailed t test were used to determine the relationship between categorical and continuous variables, respectively. Kaplan-Meier survival curves were generated to assess overall survival in patients with pT3b prostate cancer and used to compare unadjusted progression-free survival among those who underwent adjuvant and salvage radiotherapy., Results: A total of 83 (5%) of 1665 patients who underwent robotic prostatectomy were diagnosed with pT3b prostate cancer between January 2012 and July 2020. Among these, 36 patients (44%) did not receive any radiotherapy during follow-up, compared with 26 patients (31%) who received adjuvant radiotherapy and 21 (25%) who received salvage radiotherapy. The median age of our cohort was 64 (SD, 6.4) years. Mean PSA at presentation was 12.7 μg/L. Positive margins were seen in 36 patients (43%); however, there was no statistically significant difference between treatment groups ( p = 0.49). The median overall survival was 96%. There was no significant difference between the adjuvant and salvage groups in terms of biochemical progression-free survival ( p = 0.66). Five-year biochemical progression-free survival was 94% for those in the adjuvant radiotherapy group and 97% for those in the salvage radiotherapy group., Conclusions: Our audit corroborates with the recently concluded RADICALS-RT study, although we had fewer patients with positive margins. Radiotherapy can be avoided in patients with T3b prostate cancer, even if margin is positive, until there is definitive evidence of PSA recurrence. In keeping with the conclusion of RADICALS-RT, salvage radiotherapy may be preferable to adjuvant radiotherapy., Competing Interests: No conflict of interest has been declared by the authors.

Abstract: Objectives: To compare patient reported outcomes between robotic assisted surgery and non-robotic assisted surgery. Methods: This was an international web-based survey based on a qualitative research and literature review, an internet-based questionnaire was developed with approximately 70 items. The questionnaire included both closed and open-ended questions. Results: Responses were received from 193 men of whom 86 had received either open (OP) or robotic (RALP) surgery. A statistically significant (p =0.027), ranked analysis of covariance was found demonstrating higher recent distress in the robotic (RALP) surgery group. Although not statistically significant, there was a pattern of men having robotic (RALP) surgery reporting fewer urinary and bowel problems, but having a greater rate of sexual dysfunction. Conclusions: Men who opt for robotic surgery may have higher expectations for robotic (RALP) surgery, when these expectations are not fully met they may be less likely to accept the consequences of this major cancer surgery. Information regarding surgical choice needs to be tailored to ensure that men diagnosed with prostate cancer are fully informed of not only short term surgical and physical outcomes such as erectile dysfunction and incontinence, but also of potential issues with regards to masculinity, lifestyle and sexual health.

Robotic-assisted surgery has been rapidly adopted within urology practice. As a result, academic centers are challenged with the burden of how to effectively train residents and fellows to perform robotic-assisted surgery without compromising outcomes. We evaluated the perioperative outcomes of trainee involvement with robotic-assisted radical prostatectomy (RARP) within our healthcare organization. We retrospectively reviewed RARP cases performed at our institution between September 2008 and December 2010 using a single da Vinci robotic platform. Trainees consisted of urology residents and fellows who operated with staff surgeons on select operating days, whereas two staff surgeon teams performed RARP on alternate days. We compared clinicopathologic variables including operating time, estimated blood loss, surgical margin rates, and complication rates between the trainee and staff-only surgeon groups. Overall, 1,019 RARP surgeries were performed within the study period and trainees participated in 162 cases (16 %). Clinical characteristics were similar between men undergoing surgery with a trainee and those without. Positive surgical margin rates were lower for patients with pT2 disease for cases with trainee involvement (11 vs. 19 %, p = 0.02), although overall margin rates and margin rates for patients with pT3 disease were similar between the groups ( p = 0.34). Surgical cases involving trainees were longer (241 vs. 200 min, p < 0.001) and resulted in higher estimated blood loss (190 vs. 120 mL, p < 0.001) than the two staff surgeon cases. However, transfusion rates as well as intraoperative and postoperative complication rates did not differ significantly between groups. In conclusion, surgical margin rates were lower in teaching cases for patients with pT2 disease. Importantly, trainee involvement in RARP is safe, with similar perioperative outcomes to staff-only surgical cases. This information may be useful for training and surgical planning.

Obesity is a major health issue in modern society, and with the progressive widespread employment of robotic assisted radical prostatectomy (RALP), the urologist-robotic surgeon is increasingly involved in the treatment of obese patients. However, the vast majority of urological departments are not equipped with a complete set of bariatric instruments. One of the potential difficulties of robotic surgery on the morbidly obese patient is the relatively short length of the optical trocar sheath, as the optical robotic arm requires some very valuable centimeters of the sheath to hang onto. This condition may make it impossible to properly reach the peritoneal cavity with the optical trocar during the RALP procedure. We present a series of four morbidly obese patients (BMI ranging from 42.1 to 46.2) with localized prostate cancer treated with RALP. We have developed an effective and 'easy-to-implement' solution to the problem of properly elongating the sheath of the optical trocar which involves the use of the plastic cylindrical transparent protective tube of a disposable 26-Ch Amplatz sheath. The Amplatz sheath, with an internal diameter of 13 mm and length of 25 cm, perfectly fits outside of the 13-mm trocar usually employed for the optical trocar. Additionally, the cylindrical tube perfectly fits and hangs onto the robotic optical arm system. Mean operative time was 202.5 min (range 185-220 min). Mean blood loss was 284 mL (range 185-380 mL). Catheterization time and hospital stay were 5 and 6 days, respectively, in all patients. All procedures were safely completed, and no minor or major complications were reported. The optical trocar lengthening technique allowed us to properly perform RALP procedures even in severely morbidly obese patients in an urological setting not equipped for bariatric minimally invasive surgery.

Abstract: Objectives: The role of robot assisted radical prostatectomy (RARP) for high-risk prostate cancer (CaP) is controversial, as is the role of RARP in elderly men. We evaluate outcomes of elderly patients with high-risk CaP who have chosen RARP over radiation or hormonal therapy. Materials and methods: Between April 2001 and November 2009, 69 elderly patients (≥70 years) with high-risk CaP underwent RARP at our institution. High-risk CaP was defined using the D''Amico criterion, PSA ≥ 20 ng/ml, biopsy Gleason score 8–10, or clinical stage ≥ cT2C. Outcomes were retrospectively analyzed. Results: Preoperative high-risk features were PSA > 20: 11 patients (15.9%), biopsy Gleason score 8–10: 43 (62.3%), or clinical stage ≥ cT2C: 25 (36.2%). Median OR time was 175 minutes (IQR: 136.8–202.5) and median EBL was 150 cc (IQR: 100–200). There were 4 complications (5.8%): urine leak (2) and ileus (2). Median duration of stay was 1 day and no patient had a hospital stay over 3 days. On final pathology, 26 men (37.7%) had organ-confined disease with negative surgical margins and 27 (39.1%) had extracapsular extension with negative margins. Biochemical recurrence occurred in 12 patients (17.4%) at a median follow-up of 37.7 months. There was a single incidence of positive lymph nodes at the time of surgery (1.4%). Actuarial biochemical recurrence-free survival was 91% at 12 months and 86% at 36 months. Functional outcomes assessed by patient administered questionnaire at a median follow-up of 26.2 months showed an improvement in median IPSS score from 8.0 preoperatively to 5.0 postoperatively (P = 0.0004) with 53 (81.5%) of patients using 1 pad per day or less for urine control and 7 patients (33.3%) of the 21 men with preoperative SHIM score > 21 preoperatively achieving erections sufficient for intercourse. Conclusions: Robotic RP is safe and feasible in select elderly patients with high-risk CaP with good intermediate oncologic and functional outcomes. Advanced chronological age should not be an absolute contraindication for RARP in these patients. [Copyright &y& Elsevier]

Background: Radical prostatectomy is considered the gold-standard treatment for patients with localized prostate cancer. The literature suggests there is no difference in oncological and functional outcomes between robotic-assisted radical prostatectomy (RARP) and open (RRP). (2) Methods: The aim of this study was to compare continence recovery rates after RARP and RRP measured with 24 h pad weights and the International Consultation on Incontinence Questionnaire—Short Form (ICIQ-SF). After matching the population (1:1), 482 met the inclusion criteria, 241 patients per group. Continent patients with a 24 h pad test showing <20 g of urinary leakage were considered, despite severe incontinence, and categorized as having >200 g of urinary leakage. (3) Results: There was no difference between preoperative data. As for urinary continence (UC) and incontinence (UI) rates, RARP performed significantly better than RRP based on objective and subjective results at all evaluations. Univariable and multivariable Cox Regression Analysis pointed out that the only significant predictors of continence rates were the bilateral nerve sparing technique (1.25 (CI 1.02,1.54), p = 0.03) and the robotic surgical approach (1.42 (CI 1.18,1.69) p ≤ 0.001). (4) Conclusions: The literature reports different incidences of UC depending on assessment and definition of continence “without pads” or “social continence” based on number of used pads per day. In this, our first evaluation, the advantage of objective measurement through the weight of the 24 h and subjective measurement with the ICIQ-SF questionnaire best demonstrates the difference between the two surgical techniques by enhancing the use of robotic surgery over traditional surgery.

Background: We performed a retrospective comparison of surgical, oncologic, and functional outcomes after robot-assisted radical prostatectomy between patients who have undergone prior transurethral resection of prostate (TURP) to TURP-naive patients. Methods: Past robotic prostatectomy hospital data were scrutinized to form two matched groups of patients: those who have undergone prior TURP and TURP-naive patients. The perioperative and pathologic data along with functional and oncologic outcomes for a period of 3 years were compared between groups. Results: Compared with TURP-naive patients, prior TURP patients experienced longer robot-assisted laparoscopic prostatectomy times ( p  < 0.001), increased incidence of bladder neck reconstruction ( p  = 0.03), greater blood loss ( p  = 0.0001), and lesser nerve sparing ( p  < 0.01). Complication rates ( p  = 0.3), positive surgical margin ( p  = 0.4), extracapsular disease ( p  = 0.3), or seminal vesicle invasion ( p  = 0.1) were comparable between groups. Continence ( p  = 0.5) and potency ( p  = 0.1) at 1 year were not different between groups. Biochemical recurrence rates were not different at 3 years ( p  = 0.9). Diabetes slowed recovery of continence in patients with prior TURP compared with TURP-naive patients until 6 months after surgery. Conclusion: Although prior TURP makes subsequent robotic prostatectomy more technically demanding, it can be safely performed by experienced surgeons without compromising long-term functional or oncologic outcomes.
