RESUMEN
BACKGROUND: Consolidative resection or cytoreductive radical prostatectomy (CRP) may benefit men with non-organ confined prostate cancer. We report the safety, feasibility, and outcomes of robot-assisted laparoscopic CRP using a single-port (SP) or multi-port (MP) platform. METHODS: We reviewed consecutive men with clinical node positive or metastatic castrate-sensitive prostate cancer who underwent IRB-approved CRP and extended pelvic lymph node dissection using the da Vinci SP or MP Surgical Systems (Intuitive Surgical, Sunnyvale, CA) from 2015-2022. Perioperative data and Clavien-Dindo 90-day complications were recorded. RESULTS: Twenty-four men with a median age of 61 (IQR 56-69) years and prostate-specific antigen of 32.1 (IQR 21.9-62.3) ng/mL were included. Clinical N1, M1, or N1 + M1 disease were detected in 8 (33%), 9 (38%), 7 (29%) patients, respectively. There was no difference in positive margins, 41% vs. 29% (P = 0.67), lymph node yield, 21 (IQR 14-28) vs. 20 (IQR 13.5-21) nodes (P = 0.31), or estimated blood loss, 150 mL (IQR 100-200) vs. 50 mL (IQR 50-125) (P = 0.06), between the MP and SP cohorts, respectively. Hospital length of stay was significantly shorter for the SP group, same-day discharge (IQR 0-0), compared to MP, 1-day (IQR 1-1), P < 0.001. One grade III bowel obstruction and lymphocele occurred in the MP cohort. No major complications occurred in the SP cohort. CONCLUSION: Robot-assisted laparoscopic CRP is safe and feasible for select men with advanced castrate-sensitive prostate cancer.

Background and objective: Approximately two-thirds of men who undergo primary treatment for prostate cancer (PC) will experience biochemical recurrence (BCR). Salvage robot-assisted radical prostatectomy (sRARP) offers curative treatment in this disease setting and men who choose this option may avoid palliative androgen deprivation therapy (ADT). The purpose of this study was to describe long-term outcomes and patient feedback following sRARP. Methods: We reviewed data for consecutive men with biopsy-proven localized BCR who underwent sRARP and pelvic lymph node dissection at a single tertiary referral center between 2004 and 2021. Perioperative data, Clavien-Dindo complications, and functional outcomes were recorded. The Kaplan-Meier method was used to estimate prostate-specific antigen-free (≥0.2 ng/ml) survival (PSAFS) and metastasis-free survival (MFS). Three Likert-type items (score 1-5) from the validated Surgical Satisfaction Questionnaire-8 were distributed to patients postoperatively. Key findings and limitations: We included 78 men, of whom 72 (92%) had undergone primary radiotherapy and six (8%) had received primary prostate ablation. Median follow-up was 10.1 yr (interquartile range 5.8-12.4). Final pathology identified ≥pT3N0M0 in 35 patients (45%) and positive margins in 23 (29%). The overall complication rate was 50%. Of the 26 (33%) major (grade ≥III) complications, anastomotic stricture (32%) was most common. The estimated 3-, 5-, and 10-yr survival rates were 85.6% and 80.2%, 83.5% for PSAFS (n = 11), and 74.1%, 83.5%, and 70.5% for MFS (n = 23), respectively. At last follow-up, postoperative ADT had been administered to 17 patients (22%), and 39 men (50%) remained alive a decade after sRARP. Continence and potency were maintained in 33/62 (53%) and 1/16 (6%) patients, respectively. Thirty-five respondents (45%) reported median questionnaire scores (≥4) in favor of sRARP. Limitations include the small single-center series and a single query point for patient feedback. Conclusions and clinical implications: Long-term outcomes of sRARP suggest that the technical challenges and morbidity of the procedure are qualified by patient feedback and the opportunity to evade the morbidity and mortality of biochemically recurrent PC. Patient summary: We reviewed the cancer outcomes and side effects of robot-assisted surgical removal of the prostate after treatment failure with radiation or ablation for prostate cancer. We found that this type of treatment has substantial risks and long-term side effects, but the surgery provides an opportunity to cure prostate cancer and/or avoid the consequences of indefinite hormonal treatment. Overall, most men who underwent this surgery were not disappointed with their decision despite the higher risks and consequences.
RESUMEN
BACKGROUND: Population-based practice patterns in the United States reveal continent diversions are only performed in 8%-10.4% of patients.1-4 Ideally, for patients undergoing radical cystectomy the choice of urinary diversion should be influenced by clinical factors and patient preference, with discussions surrounding quality of life. Unfortunately, receipt of continent diversion has been shown to be influenced by a plethora of other factors such as surgeon preference/training, geography, socioeconomic status, gender, and hospital volume.1-3 Thus, by providing detailed instruction and long-term follow-up, we hope to mitigate some of these disparities by changing the perceptions regarding feasibility and complications of continent diversions. OBJECTIVE: To provide step-by-step instruction and to report long-term clinical outcomes in bladder cancer patients receiving an Indiana pouch continent cutaneous urinary diversion (CCUD) after robot-assisted radical cystectomy. DESIGN, SETTING, AND PARTICIPANTS: After Institutional Review Board approval, a prospectively maintained bladder cancer database was queried for patients with T1-T4, N0-N1, M0 bladder cancer undergoing radical cystectomy with CCUD at a tertiary referral center from 2004 to 2020. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Complications at 30- and 90-day were recorded according to the Clavien-Dindo classification. Continence rates were recorded by chart review. RESULTS AND LIMITATIONS: A total of 97 patients were included with a median follow-up of 93months. Clinically, 91.8% had ≤T2 disease and 29.9% received neoadjuvant chemotherapy. The median length of surgery was 8.0 hours, length of hospital stay was 8.3days, and urinary continence rate was 99.0%. The overall complication rate was 73.2% and 76.5% at 30- and 90-day, respectively. The major complication rate (Clavien III-V) was 17.5% at 30-day and 22.7% at 90-day. The most common major complications were abdominal infection and uretero-colonic stricture. The readmission rate was 21.4% and median overall survival was 108months. CONCLUSION: CCUD provides exceptional functional outcomes with acceptable complication rates compared to other diversion types. CCUD is a reliable reconstructive option and with this step-by-step video as a reference, we hope it will be offered to more patients.

OBJECTIVE: To determine whether use of an antibiotic-irrigating wound protector (AWP) reduces infectious complications after robotic radical cystectomy with extracorporeal urinary diversion (RCUD). METHODS: A prospectively maintained bladder cancer database was queried for patients undergoing robotic RCUD at a tertiary referral center one year prior to implementing an AWP and one year after (2018-2020). All diversions were performed extra-corporally. 92 patients total. 46 consecutive patients using a traditional wound protector (TWP) and 46 consecutive with an AWP. Infections were classified as symptomatic urinary tract infection, blood stream infection, and surgical site infection. The incidence of infectious complications at 30- and 90-days were compared. RESULTS: Baseline patient characteristics between the 2 groups showed no statistically significant differences. The overall complication rate was 65.2% in the TWP group and 26.1% in the AWP group at 30-days, and 67.4% vs 30.4% at 90-days. Focusing on infections, the 30-day complication rate was 30.4% in the TWP group compared to 6.5% in the AWP group (P =.003). This pattern persisted at 90-days with 37.0% in the TWP group compared to 6.5% in the AWP group (P =.004). Most complications were symptomatic UTI and blood stream infections, 14/24 (58%), requiring parenteral antibiotic treatment. CONCLUSION: We provide preliminary data showing use of an AWP can reduce infectious complications after RCUD. While larger prospective studies are warranted, our findings are a significant step towards decreasing morbidity of an already highly morbid procedure.

Evaluation of safety is of paramount importance with adoption of novel surgical technology. Although robotic surgery has become widely used in oncologic surgery, analysis of safety is lacking in comparison to traditional techniques. Standardized assessment of robotic surgical outcomes and adverse events following oncologic surgery is necessary for quality improvement with innovative technology. Between 2003 and 2016, 10,013 unique robotic operations were performed in 9,858 patients. Our prospectively maintained database was retrospectively reviewed for hospital readmissions and Clavien-Dindo grade ≥ 2 complications within 30 days. Multivariable logistic regression was used to identify predictors of surgical complications and hospital readmissions. Cases were stratified by discipline: genitourinary (n = 8240), gynecologic (n = 857), thoracic (n = 457), gastrointestinal (n = 322), hepatobiliary (n = 60), ear/nose/throat (n = 44) and general (n = 33). Intraoperative complications occurred in 42 surgeries (0.4%). Postoperative complications occurred in 946 patients [9.4%, highest grade 2 (n = 574), 3 (n = 288), 4 (n = 72), 5 (n = 10)]. Most frequent complications were ileus (154, 16.3%), anemia (91, 9.6%), cardiac arrhythmia (62, 6.6%), deep vein thrombosis/pulmonary embolus (47, 5.0%), wound infection (45, 4.8%) and urinary leak (43, 4.5%). 405 patients (4.0%) required readmission. Most common causes for hospital readmission were ileus (44, 10.9%), urinary leak (23, 5.7%), urinary tract infection (23, 5.7%), intra-abdominal abscess/fluid collection (23, 5.7%), and small bowel obstruction (19, 4.7%). On multivariable analysis, longer operative time and older age predicted complications and readmissions (p ≤ 0.02). Robotic-assisted surgery appears a safe for oncologic surgery with acceptable hospital readmission and complication rates. Older age and longer operative time were associated with complications and readmission.

BACKGROUND: Ischemia is thought to contribute to benign ureteroenteric stricture (UES) after radical cystectomy with urinary diversion (RCUD). Our institution adopted the use of ureteral perfusion assessment during all RCUDs using real-time indocyanine green angiography using the SPY fluorescence imaging platform (Stryker Corp., Kalamazoo, MI, USA). This guides the location of ureteral transection prior to ureteroenteric anastomosis. We sought to compare UES rates before and after adoption of SPY. METHODS: A retrospective chart review was undertaken for the first 47 consecutive cases of RCUD using SPY as well as the previous 47 consecutive cases, which were performed without SPY. Fisher's exact and Wilcoxon rank-sum tests were used to compare benign UES rates and the length of ureter excised during anastomosis. A p < 0.05 indicated statistical significance. RESULTS: Median follow up was 12.0 months for SPY cases and 24.3 months for non-SPY cases. The UES rate for SPY RCUDs was 0% (0/93 ureters) compared with 7.5% (7/93 ureters) for non-SPY RCUDs (p = 0.01). Amongst SPY RCUDs, 86 ureters had no hydronephrosis and 7 had mild hydronephrosis with reflux on loopogram. A total of 34.4% of ureters (32/93) had poor distal perfusion, requiring a more proximal anastomosis. The median length excised for ureters with poor distal perfusion was 3.8 cm, compared with 2.2 cm for ureters with good distal perfusion (p < 0.0001). No complications attributable to the use of SPY were noted. CONCLUSION: Use of SPY to assess ureteral perfusion was associated with a decrease in the UES rate after RCUD. A total of 34.4% of ureters demonstrated poor distal perfusion, requiring a significantly more proximal ureteroenteric anastomosis.
RESUMEN
OBJECTIVE: To report our experience with ureteroenteric anastomotic revision as initial treatment of stricture after urinary diversion. METHODS: An institutional review board-approved retrospective study was carried out. A total of 41 patients who underwent primary ureteroenteric anastamotic revision were identified between 2007 and 2015. Data analyzed included patient characteristics, type of diversion, estimated blood loss, operative time, change in renal function, length of stay, postoperative complications and time with nephrostomy/stent. Success of revision was defined as an improvement in hydronephrosis on radiographic imaging and/or reflux during pouchogram. Predictors of length of stay and complications were analyzed using analysis of covariance. RESULTS: A total of 50 renal units were revised with a success rate of 100%. The median length of stay was 6 days (2-16 days). There were a total of 15 complications (one major, 14 minor) in 14 patients (33% 30-day complication rate). The most common were wound infection (n = 4) and arrhythmia (n = 4). Robotic revision (n = 5) had a median length of stay of 3 days (2-4) with no complications. CONCLUSIONS: Primary ureteroenteric anastomotic revisions have an excellent success rate at an experienced center and might obviate the need for multiple interventions. Open revision is associated with mostly minor complications. Robotic revision might reduce the morbidity of open revision in select cases.

INTRODUCTION: Evidence for the use of perioperative chemotherapy (PC) in upper tract urothelial carcinoma (UTUC) is largely derived from level I evidence for invasive urothelial carcinoma of the bladder (UCB). There has been an increase in PC for urothelial carcinoma of the bladder, as it has disseminated into clinical practice. Therefore, we sought to not only analyze trends in the utilization of PC in UTUC, but also assess factors associated with its use in a large cancer registry database. METHODS: The National Cancer Database was queried for patients with UTUC who underwent extirpative surgery from 2004 to 2013. Predictors of receiving PC were identified using univariate and multivariate logistic regression. Temporal trends in the utilization of PC were also analyzed using a general analysis of variance linear model. RESULTS: From 2004 to 2013, there was significant increase in PC for UTUC from 9.6% to 13.8% (P = 0.0003). Neoadjuvant chemotherapy increased from 0.7% to 2.1% (P = 0.0018), whereas adjuvant chemotherapy remained relatively stable at 11.3%. Significant predictors of receiving PC on multivariate analysis were private insurance, ureter as the primary site, poorly differentiated and undifferentiated grade, lymphovascular invasion, positive margins, clinical T3 or T4 disease, nodal metastasis, and reporting from an academic research program. Patients who were≥70 years old,>50 miles to treatment center, had tumor in the kidney, or had an increased Charlson-Deyo Score were significantly less likely to receive PC. CONCLUSIONS: Over the time period studied, there has been an increase in the use of PC, primarily from increased administration of neoadjuvant chemotherapy. Its use is mostly associated with advanced pathologic characteristics. The study also highlights key demographic and socioeconomic differences that can help identify barriers to receiving PC and aid in making improvements in delivery of health care to patients with UTUC.

OBJECTIVE: To prospectively assess the ideal dosing and the value of fluorescent sentinel lymph node (LN) detection with indocyanine green (ICG) for the detection of LN metastases in intermediate- and high-risk patients undergoing robot-assisted prostatectomy and extended pelvic LN dissection (ePLND). PATIENTS AND METHODS: Twenty patients received transperineal prostatic injections of ICG. Patients were cycled through 5 doses (1.25, 2.5, 3.75, 5, and 7.5 mg) so optimal ICG dosing could be discovered early. RESULTS: ICG injection was able to identify fluorescent LN (FLN) packets in all 20 patients. Compared to the higher ICG doses, the 1.25 and 2.5 mg doses had fewer FLN packets and were abandoned after 1 dose each. The median number of FLN packets was 4.0, 6.0, and 4.5 for the respective doses of 3.75, 5.0, and 7.5 mg. The external iliac group was the most common site of fluorescence in 27.2% of patients, followed by the common iliac (21.3%), obturator (20.3%), internal iliac (18.5%), and node of Cloquet (7.7%). Seven (35%) of 20 patients had node-positive disease. Of the 5 patients that had fluorescent tissue outside of our ePLND template, 1 had a positive node present in the anterior bladder neck fat. Across all patients, ICG had 62% sensitivity, 50% specificity, 8% positive predictive value, and 95% negative predictive value in detecting LN metastases. CONCLUSION: The low sensitivity of ICG for the detection of LN metastases highlights why FLN dissection with ICG does not represent an alternative to ePLND.

PURPOSE: This article describes a novel technique for the repair of penile urethral strictures and establishes the safety, feasibility, and efficacy of this innovative surgical approach. MATERIALS AND METHODS: Patients with urethral strictures underwent a one-sided anterior dorsal oral mucosal graft urethroplasty through a penoscrotal inversion technique. The clinical outcome was considered a failure when any instrumentation was needed postoperatively, including dilatation. RESULTS: Five patients underwent the novel procedure. The patients' mean age was 58 years. The cause of stricture was instrumentation in 2 cases (40%), lichen sclerosis in 1 case (20%), and failed hypospadias repair in 2 cases (40%). The mean stricture length was 3 cm. The overall mean (range) follow-up was 6 months (range, 3-9 months). Of the 5 patients, 4 (80%) had a successful outcome and 1 (20%) had a failed outcome. The failure was successfully treated by use of a meatotomy. CONCLUSIONS: The penile inversion technique through a penoscrotal incision is a viable option for the management of penile urethral strictures with several advantages to other techniques: namely, no penile skin incision, a single-stage operation, and supine positioning.

PURPOSE: To evaluate intermediate-term oncologic outcomes in a large series of patients who were treated with robot-assisted radical cystectomy (RARC) for urothelial carcinoma of the bladder (UCB). PATIENTS AND METHODS: Between 2004 and 2010, 162 patients underwent RARC at City of Hope Cancer Center for UCB and were analyzed with respect to overall (OS), disease-specific (DSS), and disease-free survival (DFS). Descriptive statistics were used to summarize demographics and perioperative variables. The Kaplan-Meier method was used to estimate survival and recurrence. Univariable and multivariable Cox proportional hazards regression models were used to determine predictors of survival. RESULTS: Median follow-up was 52 months. Thirty-eight (23.4%) patients received neoadjuvant chemotherapy before RARC; 28% of patients were pT2 and 33% had final pathology status of pT3 or pT4. Median lymph node count was 28, and positive surgical margin rate was 4.3%. Local recurrence occurred in 11 (6.8%) patients. OS, DFS, and DSS at 3 years were 61%, 76%, and 83%, respectively. OS, DFS, and DSS at 5 years were 54%, 74%, and 80%, respectively. Predictors of OS and DFS on multivariable analysis were lymph node density, pathologic stage, and age-adjusted Charlson Comorbidity Index, while receipt of transfusion was also a negative predictor of OS. CONCLUSIONS: RARC provides an effective means of treatment of UCB in a minimally invasive fashion with comparable oncologic outcomes to that reported in the literature of open procedures.

PURPOSE: Minimally invasive surgical treatment for bladder cancer has gained popularity but standardized data on complications are lacking. Urinary diversion type contributes to complications and to our knowledge diversion types after minimally invasive cystectomy have not yet been compared. We evaluated perioperative complications stratified by urinary diversion type in patients treated with robot-assisted radical cystectomy. MATERIALS AND METHODS: We analyzed the records of 209 consecutive patients who underwent robot-assisted radical cystectomy at our institution from 2003 to 2012 with respect to perioperative complications, including severity, time period (early and late) and diversion type. All complications were reviewed by academic urologists. Urinary diversion was also done. As outcome measurements and statistical analysis, univariate and multivariate logistic regression models were used to determine predictors of various complications. RESULTS: The American Society of Anesthesiologists(®) (ASA) score was 3 or greater in 80% of patients and continent diversion was performed in 68%. Median followup was 35 months. Within 90 days 77.5% of patients experienced any complication and 32% experienced a major complication. The 90-day mortality rate was 5.3%. Most complications were gastrointestinal, infectious and hematological. On multivariate analysis patients with ileal conduit diversion had a decreased likelihood of complications compared to patients with Indiana pouch and orthotopic bladder substitute diversion despite the selection of a more comorbid population for conduit diversion. Continent diversion was associated with a higher likelihood of urinary tract infection. Our results are comparable to those of previously reported open and minimally invasive cystectomy series. CONCLUSIONS: Open or minimally invasive cystectomy is a complex, morbid procedure. Urinary diversion is a significant contributor to complications, as is patient comorbidity. Although patients with an ileal conduit had more comorbidities, they experienced fewer complications than those with an orthotopic bladder substitute or Indiana pouch diversion.

BACKGROUND: Comprehensive and standardized reporting of adverse events after robot-assisted radical cystectomy (RARC) and urinary diversion for bladder cancer is necessary to evaluate the magnitude of morbidity for this complex operation. OBJECTIVE: To accurately identify and assess postoperative morbidity after RARC using a standardized reporting system. DESIGN, SETTING, AND PARTICIPANTS: A total of 241 consecutive patients underwent RARC, extended pelvic lymph node dissection, and urinary diversion between 2003 and 2011. In all, 196 patients consented to a prospective database, and they are the subject of this report. Continent diversions were performed in 68% of cases. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: All complications within 90 d of surgery were defined and categorized by a five-grade and 10-domain modification of the Clavien system. Univariable and multivariable logistic regression analyses were used to identify predictors of complications. Grade 1-2 complications were categorized as minor, and grade 3-5 complications were categorized as major. All blood transfusions were recorded as grade ≥2. RESULTS AND LIMITATIONS: Eighty percent of patients (156 of 196 patients) experienced a complication of any grade ≤90 d after surgery. A total of 475 adverse events (113 major) were recorded, with 365 adverse events (77%) occurring ≤30 d after surgery. Sixty-eight patients (35%) experienced a major complication within the first 90 d. Other than blood transfusions given (86 patients [43.9%]), infectious, gastrointestinal, and procedural complications were the most common, at 16.2%, 14.1%, and 10.3%, respectively. Age, comorbidity, preoperative hematocrit, estimated blood loss, and length of surgery were predictive of a complication of any grade, while comorbidity, preoperative hematocrit, and orthotopic diversion were predictive of major complications. The 90-d mortality rate was 4.1%. The main limitation is lack of a control group. CONCLUSIONS: Analysis of postoperative morbidity following RARC demonstrates a considerable complication rate, though the rate is comparable to contemporary open series that followed similar reporting guidelines. This finding reinforces the need for complete and standardized reporting when evaluating surgical techniques and comparing published series.

OBJECTIVE: To evaluate the functional outcomes and complications for patients with bladder cancer undergoing robotic-assisted laparoscopic radical cystectomy with Indiana pouch continent cutaneous urinary diversion. METHODS: From February 2004 to March 2010, 34 patients underwent robotic-assisted laparoscopic radical cystectomy with Indiana pouch continent cutaneous urinary diversion reconstruction. After surgery, the complications were identified, categorized, and graded using an established 5-grade modification of the original Clavien grading system, and continence was assessed. Descriptive statistics were used in evaluating the outcomes. Fischer's exact test was used in the comparison of early and late Clavien grade III complications. RESULTS: Overall, 175 (123 early and 52 late) complications after surgery were reported in 32 (94%) of 34 patients. Within 90 days of surgery, 31 (91%) of 34 patients experienced ≥ 1 early complication. Of 34 patients, 15 (44%) reported ≥ 1 late complications (>90 days). Most (85% and 69%, respectively) early and late complications were graded as minor (grade II or less). Fewer patients with early complications required an additional intervention (grade III) compared with patients with late complications (14% vs 31%; P = .116). The most common complication in both intervals was infection, reported in 22% and 37% of patients with early and late complications, respectively. The continence data for 31 patients at a mean follow-up of 20.1 months (median 12.0) showed that all but 1 patient (97%) had daytime and nighttime continence. CONCLUSION: Patients undergoing robotic-assisted laparoscopic radical cystectomy with Indiana pouch continent cutaneous urinary diversion reconstruction have comparable complication rates and functional outcomes compared with patients in the open series.

BACKGROUND: The advanced age and comorbidities often associated with bladder cancer patients creates a difficult scenario regarding further management. Robotic-assisted laparoscopic radical cystectomy (RALRC) has had favorable results as a minimally invasive treatment option. We studied perioperative outcomes of RALRC in octogenarians to discern if there is any added benefit in this patient population. METHODS: One hundred and sixty robotic cystectomies have been performed between October 2003 and June 2010. We identified 24 octogenarians who underwent RALRC and form the cohort of the study. RESULTS: Mean patient age was 84.7 years and mean BMI was 24 kg/m². Most of the patients in the study had serious medical comorbidities, as 82.6% of them had an ASA classification ≥ 3 and 95.6% had Charlson scores ≥ 3. There was one open conversion and two patients had positive surgical margins. There were a total of 45 complications in the study, with 14 major complications observed in the 90-day period after surgery. There were five patients who had no complications, and two patients expired as a result of multiple organ failure. At 24 months the overall, disease-free and disease-specific survivals were 51.1%, 64.3%, and 79%, respectively. The 90-day mortality rate was 8.7%. CONCLUSIONS: Octogenarians undergoing RALRC have a significant risk of morbidity and mortality. The relationship between advanced age and oncologic outcomes or complications needs to be discerned further as it relates to the octogenarian. Further study is needed to delineate the safety and efficacy of this approach.

INTRODUCTION: Prostate cancer is the second leading cause of cancer death in men in the USA, and most of these deaths will occur as a result of castrate-resistant prostate cancer (CRPC) that has progressed despite androgen deprivation therapy. There has been better understanding of castration resistance and molecular mechanisms of prostate cancer progression recently, leading to new treatment strategies. AREAS COVERED: This review focuses on emerging and new therapies for castrate-resistant prostate cancer, including hormonal therapy, immunotherapy and cytotoxic agents. EXPERT OPINION: New treatment strategies have been developed in recent years and, with improved understanding of advanced CRPC, additional targeted treatments are expected in the near future. Further cost effectiveness research of these treatments is warranted before dissemination of these promising agents.

Robotic technology has enabled urologists to perform a variety of laparoscopic surgeries. Robotic surgery offers enhanced optical magnification and visualization with precise surgical movements. We report the first case series of robot-assisted laparoscopic retroperitoneal lymph node dissection for clinical stage I nonseminomatous testicular cancer in three consecutive patients. All procedures were performed using a modified template nerve-sparing approach. The mean patient age was 31 yr. Estimated blood loss was 150-200 ml; operative time was 150-240 min. Length of stay was 2 d, and there were no perioperative complications. This early series in carefully selected and well-informed patients represented a limited experience. These results may not be applicable to all surgeons. Further long-term follow-up with a larger number of patients are warranted to validate these preliminary findings.

OBJECTIVE: : There have been few reports of the use of robotic surgery to resect lung malignancies. Feasibility and safety of robotic lung resection for malignant lung lesions will be assessed by performing a retrospective analysis. METHODS: : Between September 2004 and November 2006, 21 patients (11 male and 10 female patients) underwent robotic lung resection. Twenty resections were performed for primary nonsmall cell lung cancer and two for metastatic lesions. One patient had bilateral resections for two primary tumors. Fourteen lobectomies, five segementectomies, one wedge resection, and two bilobectomies were performed. Seventy-two percent of operative procedures included mediastinoscopy and/or bronchoscopy at the time of resection. RESULTS: : Thirty-day mortality and conversion rate was 0%. The median operating room time and estimated blood loss was 3.6 hours and 100 mL, respectively. The median intensive care unit and total length of hospital stays were 2 and 4 days, respectively. Chest tubes were removed after a median of 2.0 days. The complication rate was 27%, which included atrial fibrillation, need for postoperative bronchoscopy, and pneumonia. The median tumor size and number of lymph nodes harvested was 2.3 cm and 16, respectively. All resection margins were negative. Median follow-up time was 9.8 months, with no local recurrences at this time. CONCLUSION: : Robotic lung resection appears safe and feasible and allows for significant lymph node retrieval, offers short hospital stays and low morbidity for patients undergoing surgical resection of lung malignancies. Future studies are needed to define the role of robotic surgery in lung cancer treatment.
