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.

Scrotal and testicular injuries are uncommon injuries, accounting for only a fraction of all trauma. Blunt scrotal trauma is accompanied by testicular rupture in up to 50% of cases. We present a rare case of scrotal rupture with evisceration of a viable, intact testicle after a motor vehicle accident. The patient's presentation, associated injuries, operation, and post-operative course are described. In brief, this is a case of a 69-year-old male who sustained multiple rib, pelvic, and right femur fractures in addition to scrotal injury after a motor vehicle accident. He was taken quickly to the operating room for the scrotal rupture, and his testicle was successfully replaced and scrotal laceration repaired. He did well post-operatively. This case represents one of the few accounts of this particular injury in the literature.

Objectives To determine if eliminating the prophylactic placement of a pelvic drain (PD) after robot-assisted radical prostatectomy (RARP) affects the incidence of early (90-day) postoperative adverse events. Materials and Methods In this parallel-group, blinded, non-inferiority trial, we randomized patients planning to undergo RARP to one of two arms: no drain placement (ND) or PD placement. Patients with demonstrable intra-operative leakage upon bladder irrigation were excluded. Randomization sequence was determined a-priori using a computer algorithm, and included a stratified design with respect to low vs. intermediate/high D'Amico risk classifications. Surgeons remained blinded to the randomization arm until final eligibility was verified at the end of the RARP. The primary endpoint was overall incidence of 90-day complications which, based on our standard treatment using PD retrospectively, was estimated at 13%. The non-inferiority margin was set at 10%, and the planned sample size was 312. An interim analysis was planned and conducted when 1/3 of the planned accrual and follow-up was completed, to rule out futility if the delta margin was in excess of 0.1389. Results From 2012 to 2016, 189 patients were accrued to the study, with 92 patients allocated to the ND group and 97 patients allocated to the PD group. Due to lower than expected accrual rates, accrual to the study was halted by regulatory entities, and we did not reach the intended accrual goal. ND and PD groups were comparable in median PSA (6.3 vs 5.8 respectively, p=0.5), clinical stage (p=0.8), D'Amico risk classification (p=0.4), median lymph nodes dissected (17 vs 18, p=0.2) and proportion of patients receiving an extended pelvic lymph node dissection (70.7% vs 79.4% respectively, p=0.3). Incidence of 90-day overall and major (Clavien ≥ III) complications in the ND group (17.4% and 5.4%, respectively) was not inferior to the PD group (26.8% and 5.2%, respectively; p=0.0008 and p=0.007 for difference of proportions

Optimal management of node-positive prostate cancer patients after prostatectomy remains a challenge. We evaluated clinically localized patients who demonstrated node positivity and identified predictors for secondary treatment. From 2010 to 2015, clinically localized prostate cancer patients who underwent robot prostatectomy with extended lymphadenectomy and node-positive disease on pathologic analysis were identified. Clinical N1, M1 or salvage cases were excluded. Patients were stratified based on secondary treatments. Kaplan–Meier method was used to determine the time to biochemical and metastatic recurrence. Multivariate logistic regression was used to identify predictors for additional treatment. 145 patients (45 no additional therapy, 47 adjuvant, 53 salvage) had a median follow-up of 31.2 months. Salvage patients had higher median pre-operative prostate-specific antigen (10.8 vs. 9.7 vs. 8.2, p = 0.1), higher percentage of pathologic Gleason ≥8 (50.9 vs. 38.3% and 22.2%, p

INTRODUCTION AND OBJECTIVES:Benign ureteroenteric strictures (UES) may occur after radical cystectomy with urinary diversion. Timely treatment is instrumental in preventing renal insufficiency. The...

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.

Even with advances in perioperative medical care, anesthetic management, and surgical techniques, radical cystectomy (RC) continues to be associated with a high morbidity rate as well as a prolonged length of hospital stay. In recent years, there has been great interest in identifying multimodal and interdisciplinary strategies that help accelerate postoperative convalescence by reducing variation in perioperative care of patients undergoing complex surgeries. Enhanced recovery after surgery (ERAS) attempts to evaluate and incorporate scientific evidence for modifying as many of the factors contributing to the morbidity of RC as possible, and optimize how patients are cared for before and after surgery. In this chapter, we review the preoperative, intraoperative and postoperative elements of using an ERAS protocol for RC.

With the ubiquitous use of cross-sectional abdominal imaging in recent years, the incidence of small renal masses (SRMs) has increased, and the evaluation and management of SRMs have become important clinical issues. Diagnosing a mass in the early stages theoretically allows for high rates of cure but simultaneously risks overtreatment. In the past 20 years, surgical treatment of SRMs has transitioned from radical nephrectomy for all renal tumors, regardless of size, to elective partial nephrectomy whenever technically feasible. Additionally, newer approaches, including renal mass biopsy, active surveillance for select patients, and renal mass ablation, have been increasingly used. In this chapter, we review the current evidence-based papers covering aspects of the diagnosis and management of SRMs.
