RESUMO
OBJECTIVE: Coronavirus disease-19 (COVID-19) pandemic caused delays in definitive treatment of patients with prostate cancer. Beyond the immediate delay a backlog for future patients is expected. The objective of this work is to develop guidance on criteria for prioritisation of surgery and reconfiguring management pathways for patients with non-metastatic prostate cancer who opt for surgical treatment. A second aim was to identify the infection prevention and control (IPC) measures to achieve a low likelihood of coronavirus disease 2019 (COVID-19) hazard if radical prostatectomy (RP) was to be carried out during the outbreak and whilst the disease is endemic. METHODS: We conducted an accelerated consensus process and systematic review of the evidence on COVID-19 and reviewed international guidance on prostate cancer. These were presented to an international prostate cancer expert panel (n = 34) through an online meeting. The consensus process underwent three rounds of survey in total. Additions to the second- and third-round surveys were formulated based on the answers and comments from the previous rounds. The Consensus opinion was defined as ≥80% agreement and this was used to reconfigure the prostate cancer pathways. RESULTS: Evidence on the delayed management of patients with prostate cancer is scarce. There was 100% agreement that prostate cancer pathways should be reconfigured and measures developed to prevent nosocomial COVID-19 for patients treated surgically. Consensus was reached on prioritisation criteria of patients for surgery and management pathways for those who have delayed treatment. IPC measures to achieve a low likelihood of nosocomial COVID-19 were coined as 'COVID-19 cold' sites. CONCLUSION: Reconfiguring management pathways for patients with prostate cancer is recommended if significant delay (>3-6 months) in surgical management is unavoidable. The mapped pathways provide guidance for such patients. The IPC processes proposed provide a framework for providing RP within an environment with low COVID-19 risk during the outbreak or when the disease remains endemic. The broader concepts could be adapted to other indications beyond prostate cancer surgery.

OBJECTIVE: To evaluate the coronavirus disease 2019 perioperative infection rate and mortality rate of patients undergoing urological surgeries during the early pandemic period in Spain. METHODS: This was a non-interventional multicenter prospective study carried out from 9 March to 3 May 2020 in two urology departments in Madrid, Spain. Clinical, microbiological and radiological data of patients who underwent surgery were collected from computerized medical records. RESULTS: A total of 148 patients were included in the study, and 141 were analyzed for nosocomial infection risk, after excluding previous and concomitant severe acute respiratory syndrome coronavirus type 2 infections. Elective surgeries represented 76.6% of the procedures, whereas emergent surgeries represented 23.4%. Preoperative screening was carried out with polymerase chain reaction test in 34 patients, all were negative. A total of 14 patients also had chest X-ray (not suspicious in all cases). Three patients (2.1%) developed severe acute respiratory syndrome coronavirus type 2 nosocomial infection (symptoms developed between the third day after surgery to the 14th day after hospital discharge). Time from admission to a compatible clinical case was 5.5 days (4-12 days). Two patients underwent surgery with concomitant diagnosis of coronavirus disease. The mortality rate due to severe acute respiratory syndrome coronavirus type 2 infection is 0.7%, and the specific mortality rate in patients undergoing surgery with community-acquired coronavirus disease 2019 infection was 50% (1/2). CONCLUSIONS: The nosocomial severe acute respiratory syndrome coronavirus type 2 infection rate was low in patients undergoing urological surgical procedures during the peak of the pandemic in Madrid. With appropriate perioperative screening, urological surgical activity can be carried out in safety conditions.

INTRODUCTION: While no consensus on the optimal salvage treatment exists, only 3% of these patients will get salvage radical prostatectomies due to the assumed technical challenges of this procedure. OBJECTIVES: Our goal is to analyze the perioperative, oncologic and functional outcomes of patients undergoing salvage robotic-assisted radical prostatectomy (sRARP) after primary treatment failure. MATERIALS AND METHODS: Data were prospectively collected and retrospectively reviewed from a combined database of more than 14,800 patients who had undergone RARP. We identified 96 patients who underwent sRARP after RT or ablative techniques. Primary cancer characteristics, surgical data, pathology results, perioperative complications, oncologic and functional outcomes were analyzed. RESULTS: Sixty-eight patients (70.8%) received some source of RT as a primary treatment. The remaining 28 patients: 18 (18.75%) received cryotherapy, seven (7.92%) HIFU, one electroporation, one microwave and one Tookad. complication was seen in 25 (26%) patients (21 minor and 4 major complications). Anastomotic leak was the most common complication, found in 14 (14.6%) of the cases. No rectal injuries occurred. Fourteen (15%) patients had a biochemical failure after a median follow-up of 14 (IQR 5-24) months. Fifty-five (57.3%) of them self-reported to be pad-free at 12 months. Seventeen (55%) of 31 pre-operative potent patients (SHIM score > 21), were potent with or without the use of PDE5i at 12 months. CONCLUSIONS: sRARP is a feasible alternative for PCa recurrence. Technically the procedure is challenging and should be performed by experienced PCa surgeons. Major complications are uncommon. Continence and potency recovery is possible, but at lower rates than for non-salvage patients.

OBJECTIVE: To show the feasibility, oncological and functional outcomes of neurovascular bundle (NVB) preservation during salvage robot-assisted radical prostatectomy (RARP). PATIENTS AND METHODS: In the present institutional review board-approved retrospective analysis, between January 2008 and March 2016, 80 patients underwent salvage RARP, performed by a single surgeon (V.P), because of local recurrence after primary treatment. These patients were categorized into two groups depending on the degree of nerve-sparing (NS) performed: a good-NS group (≥50% of NVB preservation) and a poor-NS group (<50% of NVB preservation). A standard transperitoneal six-port technique, using the DaVinci Surgical System (Intuitive Surgical, Sunnyvale, CA, USA), was performed, and either an anterograde or a retrograde approach was used for NVB preservation. Validated questionnaires were used preoperatively (Sexual Health Inventory for Men [SHIM] and American Urological Association scores). Potency after salvage RARP was defined as the ability to achieve a successful erection with penetration >50% of the time, while full continence after salvage RARPwas defined as 0 pads used. The Kaplan-Meier method was used for survival and predictive estimations, and regression models were used to identify the predictors of potency, continence and biochemical failure (BCF). RESULTS: The potency rate at 12 months was higher in the good-NS group (25.6% vs 4.3%; P = 0.036) regardless of previous SHIM score, and good NS tended to be predictive of potency after salvage RARP (P = 0.065). The full continence rate at 12 months and BCF rate were similar in the two groups, and non-radiation primary treatment was the only predictor of continence at 12 months after salvage RARP (P = 0.033). CONCLUSIONS: Our data support the feasibility and safety of NVB preservation for salvage RARP conducted in select patients in a high-volume institution and the subsequent better recovery of adequate erections for intercourse.

OBJECTIVES: To identify risk factors for progression in patients with invasive bladder carcinoma who were pT0/pT1/pTa after cystectomy. METHODS: We analyzed the clinical records of 97 post-cystectomy pT0/pT1/pTa patients for the following variables: hydronephrosis, carcinoma in situ (CIS), lymphovascular invasion, history of non-muscular invasive disease, residual tumor in the specimen and lymphatic invasion (pN). pN+patients were excluded from definitive analysis. The quantitative and qualitative variables were analyzed using standard statistics. The chi-square test was used to analyze associations between categorical variables. Univariate Cox proportional hazard regression analysis (enter method) was performed. The Kaplan-Meier method was used to evaluate survival and the log-rank test to assess differences between groups. Statistical significance was set at p<0.05. The analysis was performed using SPSS version 15.0. RESULTS: The study sample included 97 cases. The specimen was staged at T2 in 97% of patients after transurethral resection (TUR); After cystectomy, the specimen was staged as pT0 (R0) in 44.3% and pT1/Ta (R1) in 55.7%. Median follow-up was 47 months. Lymph node metastasis were detected in 5.2% of patients (pN+rpar; and had a negative impact on survival (p=0.02). Overall survival was 59.8% and cancer-specific survival 76.6%. Univariate analysis showed a relationship between tumor progression and the presence of CIS (p < 0.001), lymphovascular invasion (p=0.049), and hydronephrosis(p < 0.001). In the multivariate analysis, only the presence of CIS in the transurethral resection was associated with reduced cancer-specific survival (HR 100.5; 95% CI, 10.8 to 933.1; pp<0.001). CONCLUSIONS: Although the prognosis of stage pT0/pT1/pTa carcinoma in the cystectomy specimen is excellent, some patients experience progression. The presence of CIS in the transurethral resection was an independent predictor of recurrence in these cases.

PURPOSE: We designed an experimental model of renal ischemia-reperfusion to evaluate the preemptive effect of intravenous sildenafil according to the dose administered (0.7 vs 1.4 mg/kg) and the time of administration (30 minutes before ischemia or during ischemia). MATERIALS AND METHODS: A total of 20 minipigs were divided into groups of 4 each, including group 1-control, group 2-sildenafil 0.7 mg/kg intravenously 30 minutes before vascular clamping, group 3-sildenafil 0.7 mg/kg intravenously during warm ischemia, group 4-sildenafil 1.4 mg/kg intravenously 30 minutes before vascular clamping and group 5-sildenafil 1.4 mg/kg intravenously during warm ischemia. The ischemia-reperfusion model was applied using laparotomy and right kidney vascular clamping for 30 minutes, followed by unclamping and reperfusion for 45 minutes. Renal vascular flow and systemic mean arterial pressure were recorded for 45 minutes after unclamping. Mean values were compared using Student t test with significance considered at p <0.05. RESULTS: Sildenafil led to a decrease in arterial pressure compared to that in controls, especially at the dose of 1.4 vs 0.7 mg/kg, including 113.77, 109.76, 106.12, 97.41 and 82.85 mm Hg in groups 1 to 5, respectively. Renal vascular flow was significantly higher in groups 2 and 3 than in groups 1, 4 and 5 (112.82 and 111.33 vs 88.25, 87.91 and 84.37 ml per minute, respectively, p = 0.000). CONCLUSIONS: The effect of intravenous sildenafil as a preemptive drug against the hemodynamic effects of renal ischemia-reperfusion is dose dependent. The 0.7 mg/kg dose significantly increased reperfusion renal vascular flow with a small decrease in arterial pressure compared to the 1.4 mg/kg dose.

PURPOSE: We compared the outcome of second and third kidney allografts with that of the first kidney allograft in pediatric recipients. MATERIALS AND METHODS: We classified 173 cadaveric kidney recipients into 2 groups. Group 1 comprised 120 first transplants and group 2 comprised 53 retransplants, including 43 second and 10 third transplants. We compared demographic characteristics and survival in groups 1 and 2. RESULTS: Group 1 consisted of 78 boys and 42 girls with a mean ± SD age of 11.5 ± 4.2 years. Group 2 consisted of 37 boys and 16 girls with a mean age of 10.4 ± 4.7 years. One, 5, 10 and 15-year graft survival rates were 78.7%, 64.3%, 54.5% and 50.7% for first transplants vs 82.8%, 57.8%, 57.8% and 41.3%, respectively, for retransplants (p = 0.757). Patient survival at 1, 5 and 15-year was 95.8%, 89.6%, 84.9% in the first transplant group vs 93.6%, 93.6% and 93.6%, respectively, in the retransplant group (p = 0.0.63). Graft survival was significantly higher in patients who did vs did not receive calcineurin inhibitors in the 2 groups (p = 0.02). CONCLUSIONS: Kidney retransplantation in the pediatric population can yield excellent long-term outcomes, especially in patients treated with calcineurin inhibitors.

Radical cystectomy (RC) with pelvic lymph node dissection (PLND) is the standard treatment for localized muscle-invasive bladder cancer (MIBC) and non-muscle-invasive bladder cancer (NMIBC) with recurrence or high risk of progression. Also, the robotic approach to this type of surgery is well established in the literature. Our objective is to summarize in this manuscript the most relevant articles related to the robotic-assisted radical cystectomy for prostate cancer. We performed a literature review of articles describing the robotic approach to RC in patients with bladder cancer. Also, we described the procedure since the patient selection until the bladder removal. The reconstructive techniques were not included in this review. Twenty-five articles were used to divide our manuscript into key points such as preoperative patient selection and protocols, surgical technique, pathology report, oncological outcomes, complication rates, and quality of life after the procedure. Robotic-assisted radical cystectomy is feasible and safe with satisfactory oncological outcomes. The robotic approach is related to lower blood loss and fewer transfusion rates. However, when compared to open surgery, the use of this technology increases the operative time.
RESUMO
Different groups described the single-port surgery since its first report in laparoscopic procedures. However, the acceptance of this technique among urologists, even after the robotic approach, was reduced in the past years. Therefore, to overcome the challenges related to the single-port surgery, a new robotic platform named da Vinci SP was created with exclusive single port technology. We performed a non-systematic literature review regarding the single port technique in urologic surgeries since the first laparoscopic report until the da Vinci SP robotic platform. Three different periods were described (laparoscopy, robotic, and da Vinci SP), and we focused in our experience with this new single port robot. We selected different articles and summarized the information regarding the use of single-site surgery in laparoscopic procedures and the challenges of this approach. We also reported the experience of different groups using the single port robotic technique and some recent reports of the da Vinci SP approach. In our experience with this new console, we described some critical points related to our radical prostatectomy technique and the lessons learned during the introduction of this novel platform. Previous single-site procedures described some common challenges that limited the technique expansion. However, our experience with the da Vinci SP described feasible and safe procedures with acceptable intraoperative outcomes. The introduction of this platform is recent in the market, and the literature still lacks a high level of evidence describing the long-term outcomes of this new technology.
RESUMO
The benefits and outcomes of robotic surgery are well established in the literature across multiple specialties. The increasing need for and dissemination of this technology associated with high costs, demand adequate planning during its implementation. Therefore, after years of training several robotic surgeons and establishing multiple robotic programs worldwide, the purpose of this article is to focus on the necessary elements in the initial phase of establishing a robotics program. We summarized in our article crucial factors when implementing a robotic program. Therefore, we explained in detail the critical aspects of the program design, implementation, marketing, research and outcomes, and ultimately improving efficiency. The creation of a robotics planning committee composed of several hospital individuals contributes in different lines of work such as cost evaluation, staff training, and OR modifications. A multidisciplinary approach and a robotic lead surgeon are also recommended to guarantee surgical volume and satisfactory outcomes. Furthermore, market analysis should evaluate the competition with other centres and potential surgical candidates in that area. Data collection should also be considered a vital element of the program organization, which assures quality control and helps to diagnose any program deficiency. We believe that the robotic program should be individualized according to the economy and reality of each centre. The success and duration of a robotic surgery program depend on long-term results. Therefore, careful planning with a robotic committee defining the types of procedures to be performed and appropriate multidisciplinary training to avoid surgery cancelations are crucial factors in establishing a successful program.

BACKGROUND: The aim of this study was to report the overall results and the learning curve (LC) in salvage robot-assisted radical prostatectomy (sRARP) patients, in terms of morbidity, oncological and functional outcomes in a single surgeon tertiary-referral center. METHODS: One hundred and twenty patients underwent sRARP by a single surgeon (V.P.) from 2008 to 2018. To assess the trends in the learning experience they were sub-divided in 4 groups of 30 consecutive patients based on date of surgery. The Kaplan-Meier method and regression models were used to identify survival estimations and predictors of potency, continence and biochemical failure (BCF) at 12 months. RESULTS: As the learning experience for sRALP increased operative time (OT) was significantly shorter (from 139.5 to 121 minutes) and the amount of nerve-sparing (NS) undertaken increased (from 46% to 80%). While complications rate remained stable, estimated blood loss (EBL) and radiographic anastomotic leaks (RAL) decreased through the groups (from 124 to 69 ml and 40% to 16,7%, respectively). BCF and continence rates at 12 months after sRARP were similar among groups (23-36% and 36,7-50%, respectively) and chance of potency rates tended to increase (from 3.3% to 16-23%) but was not statistically significant. In a multivariate analysis, predictors for BCF were PSM and GS 8-10. Non-radiation primary treatment was the unique predictor of continence at 12 months after sRARP. CONCLUSIONS: Our data may suggest a decreasing trend in terms of OT and EBL through the sRARP learning curve. While morbidity remained stable through the time, RAL trended towards a decline. A higher degree of NS was observed through the groups and there was a slight correlation trend between surgical expertise and potency recovery. PSM and GS 8-10 were predictors of BCF and non-radiation primary treatment predicted a better continence after sRARP.

A few decades ago, minimal invasive surgery changed the way we understand and perform surgery. Before the revolution of minimal invasive techniques, we accepted and justified a certain degree of trauma on the tissues in order to provide benefit and healing to the patient. With the adoption of new technologies, we realized that we could achieve the same or even better results with fewer side effects.

Prostate cancer represents the most commonly diagnosed cancer in men and is the second-leading cause of cancer related death in the United States. Primary treatment for prostate cancer includes radiotherapy or ablative procedures such as cryotherapy, and high-intensity focused ultrasound (HIFU). Unfortunately, a large proportion of these patients, especially with high risk features, may experience disease recurrence within 10 years. Management of recurrent localized prostate cancer is heterogeneous, and radical surgery remains as a salvage option in these patients. The purpose of this article is to offer oncological arguments in favor of salvage robotic radical prostatectomy (sRARP), which could benefit a certain group of patients. Tips and tricks in order to perform a challenging salvage surgery are summarized, as evidence of modern series with acceptable morbidity rates.

BACKGROUND: Live surgery events (LSEs) have become one of the most attended activities at surgical meetings and provide a unique opportunity for the audience to observe the decision-making process used by skilled and experienced surgeons in real time. However, there is an ongoing discussion on whether patients treated during LSE are at higher risk of complications. OBJECTIVE: To examine LSE outcomes for robot-assisted radical prostatectomy (RARP) and establish patient safety and efficacy. DESIGN, SETTING, AND PARTICIPANTS: From January 2008 to April 2016, >9000 patients underwent RARP at our institution, performed by a single surgeon. From this group, 36 patients underwent live RARP surgery (LS group) transmitted via video link from our institution to an external congress. A control group was obtained from our database to compare outcomes between the LS group and patients undergoing RARP under regular circumstances. The data were prospectively collected in a customized database and retrospectively analyzed. INTERVENTION: All patients underwent RARP performed by a single surgeon at our institution. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Postoperative outcomes were compared between the LS (n=36) and the control (n=108) groups using Student's t test and analysis of variance for continuous variables, and a two-tailed Fisher's exact test for categorical variables. Statistical significance was set at p<0.05. RESULTS AND LIMITATIONS: There were no significant differences in baseline characteristics (age, body mass index, comorbidities, preoperative Gleason score, Sexual Health Inventory for Men score and American Urological Association symptom score) between the groups. The median console time was shorter for the LS group (73min, interquartile range [IQR] 70-79) than for the control group (78min, IQR 75-87; p=0.0371). No major complications were reported in either group, and only four minor complications were observed in the control group (p=0.2415). After median follow-up of 31 mo (IQR 18-50), only one patient (2.77%) in the LS group experienced biochemical recurrence, compared to four (3.71%) in the control group (p=0.7927). There was no significant difference in continence rates between the LS and control groups (97.22% vs 93.52%; p=0.7768). No differences in potency rate were evident by the end of the follow-up period (LS 69.44%, control group 70.37%; p=0.8432). The retrospective nature, the lack of randomization, and the single-institution experience are limitations of the study. CONCLUSIONS: In this series of live transmitted RARPs, perioperative results (oncological and functional outcomes and complications) were similar to those found in daily practice. After careful patient selection, LSEs are safe with minimal patient morbidity in the hands of an experienced surgeon working with a familiar surgical team. Further evaluation of the results from other surgeons at other centers is necessary. PATIENT SUMMARY: We investigated the safety of surgeries broadcast live from our institution. We found that outcomes were similar to those for patients undergoing surgery under regular circumstances in terms of the rate of complications and oncological and functional outcomes. We conclude that live transmitted surgery is safe in well-selected patients in the hands of an experienced surgeon.

OBJECTIVES: To review the main complications related to the robot-assisted laparoscopic (RAL) approach in urology and to suggest measures to avoid such issues. METHODS: A systematic search for articles of the contemporary literature was performed in PubMed database for complications in RAL urological procedures focused on positioning, access, and operative technique considerations. Each complication topic is followed by recommendations about how to avoid it. RESULTS: In all, 40 of 253 articles were included in this analysis. Several complications in RAL procedures can be avoided if the surgical team follows some key steps. Adequate patient positioning must avoid skin, peripheral nerve, and muscles injuries, and ocular and cognitive complications mainly related to steep Trendelenburg positioning in pelvic procedures. Port-site access and closure should not be neglected during minimally invasive procedures as these complications although rare can be troublesome. Technique-related complications depend on surgeon experience and the early learning curve should be monitored. CONCLUSIONS: Adequate patient selection, surgical positioning, mentorship training, and avoiding long-lasting procedures are essential to prevent RAL-related complications. The robotic surgical team must be careful and work together to avoid possible complications. This review offers several steps in surgical planning to reach this goal.
RESUMO
BACKGROUND: One of the key factors contributing to morbidity associated with salvage radical prostatectomy is a significant vesicourethral anastomosis (VUA) disruption or postoperative tissue dehiscence in the region of the distal bladder neck that causes a large prolonged urinary leak, perineal pain, and delayed catheter removal. OBJECTIVE: To describe our surgical technique using a urinary bladder extracellular matrix (UB-ECM) scaffold incorporated into the base of the VUA and the distal bladder neck during salvage robot-assisted radical prostatectomy (sRARP) and to assess outcomes and safety. DESIGN, SETTING, AND PARTICIPANTS: From March to July 2015, 15 patients underwent sRARP performed after primary therapy failure by a single surgeon. Two other groups were identified via analysis of propensity score matching. Group 2 (n=45) underwent sRARP with standard suturing without use of the graft. Group 3 (control group; n=45) underwent primary RARP with no graft placement. These two groups were compared group 1 (n=15), in which patients underwent sRARP and received the scaffold in a 1:3:3 match. SURGICAL PROCEDURE: sRARP with use of a UB-ECM scaffold in the posterior aspect of the VUA and distal bladder neck. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Clinical data were prospectively collected in a customized database and retrospectively analyzed. Analysis of variance and Student's t-test were used to test the equality of means for continuous variables, while the χ2 test was used to test categorical variables. RESULTS AND LIMITATIONS: There were no anastomotic leaks in the control group, with an average catheter time of 6.3 d (5-7 d). However, a clinically significant VUA/bladder neck disruption was observed in 16 patients (35.5%) in group 2, with a median catheterization time of 17.4 d (9-47 d), while in group 1 only one patient (6.66%) had a significant anastomotic leak on cystography (p=0.045), with median catheterization time of 11.2 d (10-52 d) for this group (p<0.05). CONCLUSIONS: Incorporation of a UB-ECM scaffold into the base of the VUA and distal bladder neck should be considered as an option to decrease morbidity associated with sRARP since it decreased the rate of VUA disruption, enhanced healing, and reduced catheterization time. This technique could be a valuable tool for all surgeons performing sRARP. PATIENT SUMMARY: We investigated the use of a scaffolding tissue graft when connecting the urethra to the bladder during salvage robot-assisted laparoscopic prostatectomy.

Robotic radical prostatectomy (RARP) is well established as a safe and effective treatment for prostate cancer. According to published studies, patients undergoing RARP are at increased risk of being diagnosed with an inguinal hernia after RARP and are four times more likely to have an inguinal hernia repair (IHR) following RARP. Several studies have demonstrated the effectiveness and safety of IHR during RARP. Overall, it has been observed that IHR adds on average, 12-15 min in total surgical time and there were no significant differences between RARP with or without IHR with respect to postoperative complications. This study analyzes a large series of patients undergoing RARP (1100) and compares them to a group that underwent RARP with IHR (39). Between December 2008 and January 2015, 1139 patients underwent RARP at Florida Hospital in Celebration, FL. Of the total patients, 39 underwent concomitant IHR. All procedures were performed by the same surgeons (urologist and general surgeon), using the same techniques of RARP and TAPP inguinal hernia repair. After 30 days, the differences were evaluated between groups regarding surgical time, EBL and postoperative complications. The average age of patients undergoing the procedure was 61.65 years. The mean procedure time was approximately 120 min (min), with an additional period of 68 min for IHR (mean = 188; p = 0.0001). There was a significant difference in BMI between the groups, 28.3 kg/m2 for patients undergoing RARP and 26.8 kg/m2 for those who underwent RARP and IHR (p = 0.028). The EBL averaged 110.87 mL, with no significant difference between groups (p = 0371). There was no significant association between clinical stage of the patient and the type of procedure performed (p = 12:35). There was no significant difference in the presence of comorbidities and the operation preformed. There were 61 events recorded postoperatively, 57 (5.2%) among patients who underwent only RARP and 4 (10.26%) among those who had both. Taken together, the small amounts of complications in both groups prevent statistical significance. This study compared two groups of patients undergoing RARP: those with IHR and those without. Our study demonstrated an increase in surgical time; however, there was no increase in postoperative complications. From the data presented, we suggest that the performance of both procedures concomitantly is feasible and safe.

The objective of this study is to determine if the use of dehydrated human amnion/chorion membrane (dHACM) allograft wrapped around the NVB during a robotic-assisted radical prostatectomy (RARP) accelerates the return to potency. 940 patients with preoperative SHIM >20 underwent RARP with some degree of bilateral NS. Of these, 235 patients underwent RARP, with bilateral placement of dHACM graft around the NVBs. They were matched in a 1:3 proportion with a similar group of patients (n = 705) who did not receive the allograft (control group or group 2). Minimum follow-up was 12 months. Postoperative outcomes were analyzed between propensity-matched dHACM graft (group 1) and non-graft groups (group 2). Kaplan-Meier survival curves were compared across techniques using the log-rank test. There were no significant demographic differences between the two groups. Potency was defined as the ability to achieve and maintain satisfactory erections firm enough for sexual intercourse, with or without the use of PDE-5 inhibitors. The mean time to potency was significantly lower in group 1 (2.37 months) versus group 2 (3.94 months) (p < 0.0001). The potency recovery rates were superior for group 1 at all early time points measured except at 12 months. The time to potency was significantly shorter in the dHACM group with full NS, 2.19 ± 1.84 versus 2.78 ± 2.70 mo. in the non-dHACM with full NS (p = 0.029). In the dHACM group with partial NS, the mean time to potency was 3.05 ± 2.32 versus 3.92 ± 3.42 mo. in the non-dHACM with partial NS (p = 0.021). Patients who received the dHACM wrap around the NVB after RARP accelerates the return to potency when compared to a similar control group without the use of the allograft. We also demonstrated that this faster return to potency occurs regardless of the degree of the NS preservation. Younger patients (<55 years of age) had the highest overall advantage if they received the graft. Our results indicate that dHACM placement at the site of the prostatic NVB does not increase the risk of BCR after RARP, neither in the presence of PSM, extra-prostatic disease (≥pT3) nor high Gleason score (Gleason ≥8).
