RESUMEN

PURPOSE: The purpose of this study was to investigate the effect of a surgically constructed bilateral peritoneal flap (PIF) as an adjunct to robot-assisted radical prostatectomy (RARP) and pelvic lymph node dissection (PLND) on the incidence of lymphoceles. MATERIALS AND METHODS: A total of 530 men with localized prostate cancer underwent a RARP with bilateral extended standardized PLND in a prospective randomized controlled trial. In group A, a PIF was created by suturing the margins of the bladder peritoneum to the ipsilateral endopelvic fascia at 2 points on each side. In group B, no PIF was created. The patients were followed 30 and 90 days after the surgery to assess the incidence, extent and treatment of lymphoceles. RESULTS: Lymphoceles occurred in 22% of group A patients and 33% of group B patients (p=0.008). Symptomatic lymphoceles were observed in 3.3% of group A patients and 8.1% of group B patients (p=0.027). Lymphoceles requiring intervention occurred significantly less frequently in group A patients (1.3%) than in group B patients (6.8%, p=0.002). The median lymphocele size was 4.3 cm in group A and 5.0 cm in group B (p=0.055). No statistically significant differences were observed in minor or major complications unrelated to lymphocele, blood loss, or surgical time between groups A and B. CONCLUSIONS: Bilateral PIFs in conjunction with RARP and PLND significantly reduce the total incidence of lymphoceles, the frequency of symptomatic lymphoceles and the rate of associated secondary interventions.

RESUMEN

PURPOSE: Salvage lymph node dissection is a rescue treatment for patients with nodal recurrence after radical prostatectomy. Very limited data are available on robotic salvage lymph node dissection. Our purpose was to investigate perioperative and oncological outcomes of robotic salvage lymph node dissection in a large monocentric series. MATERIALS AND METHODS: Perioperative data, complications within 30 days after surgery and oncological outcomes as assessed by histology, prostate specific antigen changes, prostate specific antigen nadir after salvage lymph node dissection, and time to further therapy were analyzed. To identify predictive factors for oncological outcome, Kaplan-Meier and Cox-regression analyses were performed. For cases with a mismatch between preoperative positron emission tomography/computed tomography and the number of histologically positive lymph nodes, prostate specific membrane antigen immunohistochemistry was performed on removed lymph nodes. RESULTS: A total of 68 patients underwent robotic salvage lymph node dissection with a median operation time of 126 minutes, a blood loss of 50 ml, and a length of stay of 4 days. No major complications (>Clavien 3) occurred. Median followup was 12.1 months. Median time to further therapy was 12.4 months, 37% of patients experienced complete biochemical response (prostate specific antigen <0.2 ng/ml) and 11% reached an undetectable prostate specific antigen, which was maintained for >1 year in 3 cases. Lower preoperative prostate specific antigen, longer time between radical prostatectomy and salvage lymph node dissection, preoperative prostate specific membrane antigen positron emission tomography/computed tomography and complete biochemical response after salvage lymph node dissection were significant predictors of longer therapy-free survival (all p <0.005). Prostate specific membrane antigen immunohistochemistry revealed that prostate specific membrane antigen positron emission tomography/computed tomography tends to miss small lymph node metastases <5 mm. CONCLUSIONS: Robotic salvage lymph node dissection is a feasible approach with low perioperative morbidity and delays further systemic therapy in most patients. Prostate specific membrane antigen positron emission tomography/computed tomography detection is mostly limited to tumor foci >5 mm.

RESUMEN

BACKGROUND: Robot-assisted partial nephrectomy (RAPN) has become widely accepted, but its different underlying types of learning curves have not been comparatively analyzed to date. This study aimed to determine and compare the impact that the learning curve of the department, the console surgeon, and the bedside assistant as well as patient-related factors has on the perioperative outcomes of RAPN. METHODS: The study retrospectively analyzed 500 consecutive transperitoneal RAPNs (2007-2018) performed in a tertiary referral center by 7 surgeons and 37 bedside assistants. Patient characteristics and surgical data were obtained. Experience (EXP) was defined as the current number of RAPNs performed by the department, the surgeon, and the assistant. As the primary outcome, the impact of EXP and patient-related factors on perioperative outcomes were analyzed and compared. As the secondary outcome, a cutoff between "experienced" and "inexperienced" was defined. Correlation and regression analysis, receiver operating characteristic curve analysis, Fisher's exact test, and the Mann-Whitney U test were performed, with p values lower than 0.05 denoting significance. RESULTS: The EXP of the department, the surgeon, and the assistant each has a major influence on perioperative outcome in RAPN irrespective of patient-related factors. Perioperative outcomes improve significantly with EXP greater than 100 for the department, EXP greater than 35 for the surgeon, and EXP greater than 15 for the assistant. CONCLUSIONS: The perioperative results of RAPN are influenced by three different types of learning curves including those for the surgical department, the console surgeon, and the assistant. The influence of the bedside assistant clearly has been underestimated to date because it has a significant impact on the perioperative outcomes of RAPN.

RESUMEN

PURPOSE: A number of observational clinical studies suggest that prior primary tumor treatment favorably influences the course of metastatic prostate cancer (PCa), but its mechanisms of action are still speculative. Here, we describe the long-lasting sensitivity to various forms of androgen deprivation in patients after radical prostatectomy (RP) for locally advanced PCa as one potential mechanism. METHODS: A consecutive series of 115 radical prostatectomies after inductive therapy for T4 prostate cancer was re-analyzed, and long-term survival, as well as recurrence patterns and responses to different forms of hormonal manipulation, were assessed. RESULTS: The estimated biochemical response-free, PCa-specific, and overall survival rates after 200 months were 20%, 65%, and 47% with a median overall survival of 156 months. The majority of patients, although not cured of locally advanced PCa (84/115), showed long-term survival after RP. PCa-specific and overall survival rates of these 84 patients with biochemical recurrence were 61% and 44% at 150 months. Long-term sensitivity to ADT was found to be the main reason for the favorable tumor-specific survival in spite of biochemical recurrence. CONCLUSIONS: Sensitivity to primary or secondary hormonal manipulation was the main reason for the long-term survival of patients who had not been cured by surgery only. The results suggest that treatment of the primary tumor-bearing prostate delays castration-resistant PCa and enhances the effect of hormonal therapies in a previously unknown manner. The underlying cellular and molecular mechanisms need to be explored in more detailed analyses, which could profoundly impact treatment concepts of locally advanced and metastatic PCa.

RESUMEN

OBJECTIVES: To determine the outcomes of complete surgical resection of T4 prostate cancer after inductive androgen-deprivation therapy (ADT), as inductive ADT and subsequent radical prostatectomy (RP) is not recommended by any guideline yet. PATIENTS AND METHODS: A monocentric RP database was queried for patients initially diagnosed with T4 prostate cancer, considered primarily as inoperable because of a fixed mass defined by rectal examination in combination with high PSA level and/or large foci of biopsy confirmed undifferentiated prostate cancer. Treatment consisted of primary ADT until PSA nadir with consecutive RP. Patients underwent retropubic RP (RRP) or robot-assisted laparoscopic RP (RALP) after inductive ADT until achievement of the PSA nadir, which is in general reached after 6-7 months. The intraoperative course and complications were analysed. Finally, Kaplan-Meier estimates were calculated for overall survival (OS) and prostate cancer-specific survival (PCSS). RESULTS: We retrospectively identified 116 patients treated between 2000 and 2014. At diagnosis, the median (range) PSA level was 37.6 (2.44-284) ng/mL. The preoperative median (range) PSA after inductive ADT was 0.73 (0.01-34) ng/mL. Thereafter, patients underwent RRP or, since 2006, RALP. The median (95% confidence interval) OS was 156 (118.9-193.1) months. The PCSS at 150 months was 82%. CONCLUSIONS: Surgical therapy of primarily inoperable prostate cancer is feasible and safe after inductive ADT. The OS of this cohort seems comparable with results described for patients with primary operable high-risk prostate cancer.

RESUMEN

BACKGROUND: Kidney autotransplantation (KAT) is the ultimate approach for nephron-sparing surgery. It is a rarely used method in renal tumor surgery today as minimal invasive and open techniques for nephron-sparing surgery improve constantly. In this publication, the complication rate and the long-term functional and oncological outcome at a single center are analyzed. METHODS: A prospectively constructed database of patients with renal tumors who underwent renal surgery was retrospectively analyzed to identify patients with KAT and describe surgical and oncological outcomes and to obtain long-term follow-up. Data collection included detailed surgical technique, complications (Clavian-Dindo), and hospital stay, as well as functional and oncological outcome and long-term follow-up. RESULTS: Between 1976 and 2013, 12 patients (median age 50.5 years) underwent KAT for highly complex renal masses: in five cases for complex renal cell carcinoma (RCC), five cases for complex upper urinary tract carcinoma (UTUC), one case for a renal metastasis, and one case for nephroblastoma. The nephrectomy or nephron-ureterectomy was performed open via a flank or transabdominal. The median surgical time was 360 min (range 270-490 min). Intraoperatively, six cases required blood transfusions (50%). Six patients (50%) developed significant postoperative complications (Clavian-Dindo > 2). In two patients, intermittent hemodialysis for delayed graft function (16.6%) was needed, and in six cases (50%), additional blood transfusions postoperatively were necessary. At discharge from hospital, all patients had functioning grafts. The median hospital stay was 29.5 days (range 18-35). At follow-up (median follow-up of 83.5 ± 40.7 months), six patients had died (50%)-all with functioning grafts (free from hemodialysis). In five cases, recurrence of primary tumor or metastatic disease was recorded. In four cases, the recurrent carcinoma could be resected; in detail, UTUC in three cases and one partial nephrectomy of the autotransplanted kidney was performed. One patient suffered from bone and lung metastasis. Two patients died finally tumor-related. Five patients (41.6%) are presently alive, without evidence of tumor relapse. One patient developed terminal renal failure requiring hemodialysis 105 months after autotransplantation. One additional patient was lost to follow-up; after 69 months, this patient had a functioning kidney and no evidence of disease-recurrence at the last follow-up. A cumulative number of 1424 months without hemodialysis was gained for these 12 patients. In the literature to date, most KAT are performed in benign disease, with minor but frequent complication. Here, we report the largest series of KAT for malignant kidney tumors. The complication rates are similar, compared to the recently reported series for benign indications with an improved graft survival rate. Since KAT requires a complex and challenging surgical approach, it should be performed by experienced kidney transplant surgeons. CONCLUSION: In very complex cases involving renal tumors and multi-morbidity, patients should be counseled well before KAT is considered. At the same time, KAT should not be abandoned in these very rare cases, especially when a nephron-sparing approach is otherwise not feasible. KAT can maintain renal function and quality of life and extend expectancy of life.

RESUMEN

The horseshoe kidney is one of the most common congenital disorders affecting the urogenital system. Following a fusion of the lower kidney poles, which in turn lead to the formation of an isthmus, this anatomical variation is accompanied by other characteristic properties like an incomplete ascension, ventral rotation of the pelvices as well as atypical vascular supply. Even though renal carcinoids and Wilms tumors are more common in horseshoe kidneys, the incidence of renal cell carcinomas seems to be unaffected. Here we report the case of a locally advanced renal cell carcinoma with extensive venous invasion occurring in a horseshoe kidney and its complex surgical management. The whole primary tumor as well as a majority of venous tumor thrombi could be removed by a combination of 2/3 nephrectomy and cavotomy with thrombectomy. During 1 year of follow-up, the patient neither suffered from a tumor relapse, nor did he require renal replacement therapy. Thus, we conclude that even in cases of RCC where advanced disease is associated with complex anatomical situations, organ-preserving surgical treatment should be pursued to achieve excellent functional and oncological results.

RESUMEN

OBJECTIVES: To compare robot-assisted laparoscopic adrenalectomy (RALA) and open adrenalectomy (OA) with regard to intra-operative complications, peri-operative outcome and cost effectiveness. SUBJECTS AND METHODS: Functional and statistical data from patients who underwent OA or RALA between 2001 and 2015 were prospectively recorded including intra- and postoperative outcomes. Data on per-day costs from current census reports (€540/day and €1 145/day for normal and intermediate care [IMC]) were also used to evaluate treatment costs. Additional costs for RALA were assumed at €2288 as reported in the current literature. Patients were matched by American Society of Anesthesiologists score, age, side of surgery and gender for comparison of OA and RALA. A total of 28 matched pairs were analysed with regard to patient characteristics, peri-operative outcomes and cost-effectiveness. Statistical significance of outcome variables was determined using Student's t-test and Pearson's chi-squared test. RESULTS: As a result of the matching process, patient groups did not differ in their main characteristics. Length of hospital stay was shorter for RALA than for OA (11.1 ± 4.8 vs 6.8 ± 1.2 days; P < 0.01) as was IMC treatment (2.3 ± 1.7 vs 1.2 ± 0.4 days; P < 0.01). The mean operating time was longer for RALA (128.5 ± 46.5 vs 102.2 ± 44.5 min; P = 0.03), but the last 10 RALA procedures (mean: 97.1 ± 35.2 min) were similar to OA. The rate of complications was similar in the two groups. Estimated costs were €8 627.5 for OA and €7 334 for RALA. CONCLUSIONS: The study showed that RALA was safe and cost-effective compared with OA. Increasing experience leads to similar operating times, putting high-volume centres at an advantage.

RESUMEN

PURPOSE: To assess clinical outcomes and reimbursement costs of open and robotic-assisted radical prostatectomies in Germany. METHODS: Perioperative data of 499 open (2003-2006) and 932 (2008-2010) robotic-assisted radical prostatectomies as well as longitudinal reimbursement costs of an anonymized health insurance research database from Germany containing data of patients who underwent robotic-assisted or open radical prostatectomy were retrospectively analysed in a single-centre study. RESULTS: Significantly better outcomes after robotic-assisted vs. open prostatectomy were observed in regards to positive surgical margins (13.3 vs. 22.4%; p < 0.0001), intraoperative transfusions (0.1 vs. 2.6%; p < 0.0001), hospitalization (8.7 vs. 15.2 days; p < 0.0001) and duration of catheter (6.6 vs. 12.8 days; p < 0.0001). Operating time was significantly longer with robotic-assisted radical prostatectomy when compared to open surgery (184.4 vs. 128.0 min; p < 0.0001), while intraoperative complications showed a similar occurrence between both groups. Significant fewer postoperative complications were observed after robotic-assisted radical prostatectomy (26.5 vs. 42.5%; p < 0.0001) and rate of re-admission was lower for the robotic patients (13.6 vs. 19.4%; p = 0.0050). While insurance costs were higher in the 2 years before radical prostatectomy for the patients who underwent a robotic procedure (4,241.60 vs. 3,410.23 €; p = 0.202), additive costs of care of the year of surgery plus the 2 following years were less for the robotic cohort when compared to the costs incurred by the open group (21,673.71 vs. 24,512.37 €; p = 0.1676). CONCLUSIONS: The observed clinical advantages of robotic-assisted radical prostatectomy seem to result in reduced health insurance cost postoperatively when compared to open surgery. This should be taken into consideration regarding reimbursement and implementation of a clinically superior method.

RESUMEN

OBJECTIVES: To explore the views of experts about the development and validation of a robotic surgery training curriculum, and how this should be implemented. MATERIALS AND METHODS: An international expert panel was invited to a structured session for discussion. The study was of a mixed design, including qualitative and quantitative components based on focus group interviews during the European Association of Urology (EAU) Robotic Urology Section (ERUS) (2012), EAU (2013) and ERUS (2013) meetings. After introduction to the aims, principles and current status of the curriculum development, group responses were elicited. After content analysis of recorded interviews generated themes were discussed at the second meeting, where consensus was achieved on each theme. This discussion also underwent content analysis, and was used to draft a curriculum proposal. At the third meeting, a quantitative questionnaire about this curriculum was disseminated to attendees to assess the level of agreement with the key points. RESULTS: In all, 150 min (19 pages) of the focus group discussion was transcribed (21 316 words). Themes were agreed by two raters (median agreement κ 0.89) and they included: need for a training curriculum (inter-rater agreement κ 0.85); identification of learning needs (κ 0.83); development of the curriculum contents (κ 0.81); an overview of available curricula (κ 0.79); settings for robotic surgery training ((κ 0.89); assessment and training of trainers (κ 0.92); requirements for certification and patient safety (κ 0.83); and need for a universally standardised curriculum (κ 0.78). A training curriculum was proposed based on the above discussions. CONCLUSION: This group proposes a multi-step curriculum for robotic training. Studies are in process to validate the effectiveness of the curriculum and to assess transfer of skills to the operating room.

RESUMEN

PURPOSE: Positive surgical margins (PSM) during robot-assisted radical prostatectomy (RARP) negatively influence patients' prognosis. The aim of our study was to identify risk factors for PSM in patients with organ-confined prostate cancer (PCa). METHODS: A clinical database of all patients that underwent a RARP at our institution was used. Uni- and multivariable logistic regression analyses were conducted on the PSM rates for all patients with organ-confined PCa. RESULTS: Altogether, 1,600 patients were identified, including 1,085 organ-confined PCa with a PSM rate of 7.8%. On multivariable analysis, bilateral nerve-sparing (OR 3.025, 95% CI 1.587-5.765), surgeon volume <200 cases (OR 1.881, 95% CI 1.120-3.159) and a preoperative PSA >10 ng/ml (OR 3.674, 95% CI 1.379-9.796) remained independent prognostic factors. In a subgroup of patients undergoing a nerve-sparing RARP, the quality of the prostate biopsy (OR 2.398, 95% CI 1.325-4.341) was the sole independent risk factor for a PSM. CONCLUSION: An elevated preoperative PSA, surgical experience and a nerve-sparing procedure are all significantly associated with a higher risk for a PSM after RARP. For those undergoing a nerve sparing RARP, an accurate preoperative biopsy with detailed information on the location of positive cores is essential to prevent PSMs.

RESUMEN

BACKGROUND: Partial nephrectomy (PN) preserves renal function and has become the standard approach for T1a renal cell carcinoma (RCC). However, there is still an ongoing debate as to which patients will actually derive greater benefit from partial than from radical nephrectomy (RN). The aim of this study was to retrospectively evaluate the impact of the type of surgery on overall survival (OS) in patients with localized RCC. METHODS: Renal surgery was performed in 4326 patients with localized RCC (pT ≤ 3a N/M0) at six German tertiary care centers from 1980 to 2010: RN in 2955 cases (68.3%), elective (ePN) in 1108 (25.6%), and imperative partial nephrectomy (iPN) in 263 (6.1%) cases. The median follow-up for all patients was 63 months. Kaplan-Meier and Cox regression analyses were carried out to identify prognosticators for OS. RESULTS: PN was performed significantly more often than RN in patients presenting with lower tumor stages, higher RCC differentiation, and non-clear cell histology. Accordingly, the calculated 5 (10)-year OS rates were 90.0 (74.6)% for ePN, 83.9 (57.5)% for iPN, and 81.2 (64.7)% for RN (p < 0.001). However, multivariate analysis including age, sex, tumor diameter and differentiation, histological subtype, and the year of surgery showed that ePN compared to RN still qualified as an independent factor for improved OS (HR 0.79, 95% CI 0.66-0.94, p = 0.008). CONCLUSION: Even allowing for the weaknesses of this retrospective analysis, our multicenter study indicates that in patients with localized RCC, PN appears to be associated with better OS than RN irrespective of age or tumor size.

RESUMEN

OBJECTIVE: To characterise the surgical feasibility and outcomes of robot-assisted radical cystectomy (RARC) for pathological T4 bladder cancer. PATIENTS AND METHODS: Retrospective evaluation of a prospectively maintained International Radical Cystectomy Consortium database was conducted for 1118 patients who underwent RARC between 2003 and 2012. We dichotomised patients based on pathological stage (≤pT3 vs pT4) and evaluated demographic, operative and pathological variables in relation to morbidity and mortality. RESULTS: In all, 1000 ≤pT3 and 118 pT4 patients were evaluated. The pT4 patients were older than the ≤pT3 patients (P = 0.001). The median operating time and blood loss were 386 min and 350 mL vs 396 min and 350 mL for p T4 and ≤pT3, respectively. The complication rate was similar (54% vs 58%; P = 0.64) among ≤pT3 and pT4 patients, respectively. The overall 30- and 90-day mortality rate was 0.4% and 1.8% vs 4.2% and 8.5% for ≤pT3 vs pT4 patients (P < 0.001), respectively. The body mass index (BMI), American Society of Anesthesiology score, length of hospital stay (LOS) >10 days, and 90-day readmission were significantly associated with complications in pT4 patients. Meanwhile, BMI, LOS >10 days, grade 3-5 complications, 90-day readmission, smoking, previous abdominal surgery and neoadjuvant chemotherapy were significantly associated with mortality in pT4 patients. On multivariate analysis, BMI was an independent predictor of complications in pT4 patients, but not for mortality. CONCLUSIONS: RARC for pT4 bladder cancer is surgically feasible but entails significant morbidity and mortality. BMI was independent predictor of complications in pT4 patients.

RESUMEN

BACKGROUND: The first robot-assisted kidney transplantation (RAKT) was conducted in 2010, and the first time in Germany in 2016. As more than 5 years have passed, current evidence, technological developments and the latest (German) experience are presented. OBJECTIVES: The current evidence and experience of RAKT was investigated from an international and German perspective. MATERIALS AND METHODS: In a systemic search, relevant publications were analyzed and compared with the experiences at a German urological transplant department. RESULTS: From an international perspective, RAKT can now be considered a standard procedure at experienced departments, as more than 680 RAKT have been documented in Europe. The functional results are excellent with low complication rates and good mid- to long-term functional outcomes. Although RAKT was initially only performed with living organ donations, it has also been successfully conducted with cadaveric grafts. The surgical technique can be applied in challenging and complex situations, such as for arteriosclerotic recipient vessels or for kidney transplantations in children. Although RAKT is still not widely performed in Germany, the university hospital in Marburg, the third urological department in Germany, has successfully initiated a robotic transplant program. CONCLUSIONS: Compared to open kidney transplantation, robot-assisted kidney transplantation enables at least noninferior results. It further appears to translate the well-documented advantages of minimally invasive surgery to kidney transplantation. However, its spread throughout Germany is only slowly increasing, possibly because only a handful of urological departments still perform kidney transplantations.

RESUMEN

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by the presence of proliferative lesions throughout the body. Management of TSC is challenging because patients have a multifaceted systemic illness with prominent neurological and developmental impact as well as potentially severe kidney, heart and lung phenotypes; however, every organ system can be involved. Adequate care for patients with TSC requires a coordinated effort involving a multidisciplinary team of clinicians and support staff. This clinical practice recommendation was developed by nephrologists, urologists, paediatric radiologists, interventional radiologists, geneticists, pathologists, and patient and family group representatives, with a focus on TSC-associated kidney manifestations. Careful monitoring of kidney function and assessment of kidney structural lesions by imaging enable early interventions that can preserve kidney function through targeted approaches. Here, we summarize the current evidence and present recommendations for the multidisciplinary management of kidney involvement in TSC.

RESUMEN

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: There is evidence from large abdominal surgeries and some open cystectomy series that multifactorial fast-track regimens shorten postoperative convalescence without any effect on morbidity and mortality. Such a regimen is of particular interest in combination with minimally invasive techniques, as early patient recovery demands for more rapid nutrition and mobilisation schemes. The present study, in a single institution, reports on the design, application and results of a fast-track protocol in patients undergoing robot-assisted laparoscopic cystectomy. There was no evidence of a higher incidence of complications with the fast-track regimen and postoperative recovery was faster. OBJECTIVES: To evaluate the feasibility and effectiveness of a multifactorial fast-track (FT) regimen on perioperative outcomes in patients undergoing robot-assisted laparoscopic cystectomy (RALC) with extracorporeal urinary diversion. To point out that morbidity and mortality of radical cystectomy have improved markedly over the last decades and RALC is an emerging technique showing further advances in postoperative recovery, thus demanding for more rapid nutrition and mobilisation schemes. PATIENTS AND METHODS: A non-randomised cohort study of 63 patients who underwent RALC at one institution between January 2007 and March 2010. In all, 31 patients underwent RALC without FT and 31 RALC with FT. One patient required conversion to open surgery and was therefore excluded from the study. The FT regimen included early nutrition and the quickest possible mobilisation, while mechanical bowel preparation before surgery, as well as preoperative fasting and nasogastric or abdominal drains after surgery, were omitted. Demographics, perioperative and complication data (according to modified Clavien system), as well as required opioid pain medication were documented prospectively and compared between RALC patients with and without FT. RESULTS: Groups were comparable for demographics, risk factors and clinical stage as well as operative parameters, e.g. mean operating room time, estimated blood loss, lymph nodes removed and postoperative haemoglobin level. In the FT group, abdominal drains were mostly omitted and nasogastric tubes were removed immediately after surgery. There were significant differences in the mobilisation within the room (17.5 vs 31.2 h), the time to a regular diet (4.0 vs 6.6 days) and a remarkably lower use of postoperative morphine equivalents (57.3 vs 92.4 mg) for patients receiving FT. There were no significant differences in the overall complication rates or major complications based on Clavien classification. The informative value of the study is limited by its single-centre, non-randomised design, a relatively small sample size and a possible learning curve bias. CONCLUSIONS: Combining RALC with FT is feasible in the perioperative treatment of these patients. Multifactorial postoperative regimens seem to quicken postoperative recovery of RALC patients without increasing their risk of postoperative complications.

RESUMEN

OBJECTIVE: To evaluate surgeons adherence to current clinical practice, with the available evidence, for robot-assisted radical prostatectomy (RARP) and offer a baseline assessment to measure the impact of the Pasadena recommendations. Recently, the European Association of Urology Robotic Urology Section (ERUS) supported the Pasadena Consensus Conference on best practices in RARP. SUBJECTS AND METHODS: This survey was performed in January 2012. A specific questionnaire was sent, by e-mail, to 145 robotic surgeons who were included in the mailing-list of ERUS members and working in different urological institutions. Participating surgeons were invited to answer a multiple-choice questionnaire including 24-items evaluating the main RARP surgical steps. RESULTS: In all, 116 (79.4%) invited surgeons answered the questionnaire and accepted to participate to the ERUS survey. In all, 47 (40.5%) surgeons performed >100 RARPs; 41 (35.3%) between 50 and 100, and 28 (24.1%) <50 yearly. The transperitoneal, antegrade technique was the preferred approach. Minimising bladder neck dissection and the use of athermal dissection of the neurovascular bundles (NVBs) were also popular. There was more heterogeneity in the use of energy for seminal vesicle dissection, the preservation of the tips of the seminal vesicle and the choice between intra- and interfascial planes during the antero-lateral dissection of the NVBs. There was also large variability in the posterior and/or anterior reconstruction steps. CONCLUSIONS: The present study is the first international survey evaluating surgeon preferences during RARP. Considering that the results were collected before the publication of the Pasadena recommendations, the data might be considered an important baseline evaluation to test the dissemination and effects of the Pasadena recommendations in subsequent years.

RESUMEN

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Lymph node dissection and it's extend during robot-assisted radical cystectomy varies based on surgeon related factors. This study reports outcomes of robot-assisted extended lymphadenectomy based on surgeon experience in both academic and private practice settings. OBJECTIVE: To evaluate the incidence of, and predictors for, extended lymph node dissection (LND) in patients undergoing robot-assisted radical cystectomy (RARC) for bladder cancer, as extended LND is critical for the treatment of bladder cancer but the role of minimally invasive surgery for extended LND has not been well-defined in a multi-institutional setting. PATIENTS AND METHODS: Used the International Robotic Cystectomy Consortium (IRCC) database. In all, 765 patients who underwent RARC at 17 institutions from 2003 to 2010 were evaluated for receipt of extended LND. Patients were stratified by age, sex, clinical stage, institutional volume, sequential case number, and surgeon volume. Logistic regression analyses were used to correlate variables to the likelihood of undergoing extended LND. RESULTS: In all, 445 (58%) patients underwent extended LND. Among all patients, a median (range) of 18 (0-74) LNs were examined. High-volume institutions (≥100 cases) had a higher mean LN yield (23 vs 15, P < 0.001). On univariable analysis, surgeon volume, institutional volume, and sequential case number were associated with likelihood of undergoing extended LND. On multivariable analysis, surgeon volume [odds ratio (OR) 3.46, 95% confidence interval (CI) 2.37-5.06, P < 0.001] and institution volume [OR 2.65, 95% CI 1.47-4.78, P = 0.001) were associated with undergoing extended LND. CONCLUSIONS: Robot-assisted LND can achieve similar LN yields to those of open LND after RC. High-volume surgeons are more likely to perform extended LND, reflecting a correlation between their growing experience and increased comfort with advanced vascular dissection.
