Primary embryonal rhabdomyosarcomas of the kidney are extremely rare, especially in adults. The presented case, a 32-year-old female with a background of autosomal polycystic kidney disease, was initially referred with a left hemorrhagic renal cyst. Despite angioembolization, she eventually underwent radical nephrectomy which revealed the diagnosis of embryonal rhabdomyosarcoma.

Article Synopsis
  • A hierarchical structure in the operating room (OR) may hinder communication and patient safety, particularly through its impact on the surgical team's interactions related to risk awareness.
  • The study analyzed recordings from 10 robot-assisted prostatectomies to assess how team members communicated about risks, noting that hierarchy did not significantly affect the frequency of risk-related utterances.
  • Results indicated that off-console communication yielded higher quality risk discussions, as proactive statements were associated with better situational awareness (SA) scores compared to reactive ones on the console.

Introduction: During robot-assisted surgery (RAS), changes to the operating room configuration pose challenges to communication by limiting team members' ability to see one another or use gesture. Referencing (the act of pointing out an object or area in order to coordinate action around it), may be susceptible to miscommunication due to these constraints.

Objectives: Explore the use of microanalysis to describe and evaluate communicative efficiency in RAS through examination of referencing in surgical tasks.

Article Synopsis
  • The study analyzed outcomes of patients with prior pelvic surgery or radiation who underwent robot-assisted radical cystectomy (RARC) from 2005-2018.
  • Patients were categorized into three complexity grades based on their surgical history, with higher grades reflecting more extensive previous surgeries or radiation.
  • Results showed that higher complexity groups (grades 2 and 3) experienced more complications within 90 days post-surgery, but there was no increase in readmission rates among these patients.

Reconstruction of the ureter is still regarded as a sophisticated approach demanding absolute dedication of the urologists. Similarly, iatrogenic ureteral injuries, as well as strictures, are quite common complexities of the pelvic and gynecological surgeries which if left untreated could lead to short as well as long-term issues. Presently, a case of a post-caesarian section along with hysterectomy of 40 years old woman has been presented that has resulted in distal left ureteral injury.

Since the introduction of robot-assisted radical cystectomy, efforts have been made to meet the standards in terms of perioperative safety and oncological efficacy. Several randomized controlled studies and meta-analyses, and multi-institutional studies have shown comparable outcomes of robot-assisted radical cystectomy when compared with the conventional open approach. In this review, we aimed to describe the surgical technique of robot-assisted radical cystectomy and urinary diversion, and perioperative, pathological, oncological and functional outcomes.

The robot-assisted approach to radical prostatectomy (RARP) has been adopted worldwide as an acceptable alternative to open prostatectomy owing to improved visualization and dexterity for surgeons, with improved recovery and convalescence for patients. However, the associated cost of installation of robot as well as running costs may hamper its utilization. We sought to investigate and identify the drivers of cost at our institution and implement changes that could reduce costs.

Purpose: We sought to determine the trend of neoadjuvant chemotherapy use for nonmetastatic muscle invasive urothelial bladder cancer and whether it is associated with adverse perioperative morbidity after robot-assisted radical cystectomy.

Materials And Methods: We retrospectively reviewed the IRCC (International Robotic Cystectomy Consortium) database between 2006 and 2017. After excluding patients with nonmuscle invasive bladder cancer the patients were divided into 2 groups, including those who did vs did not receive neoadjuvant chemotherapy.

Purpose: Radical cystectomy is the gold standard for nonmetastatic muscle invasive bladder cancer and for refractory nonmuscle invasive disease. Compared to open radical cystectomy, robot-assisted radical cystectomy has been shown to provide comparable early oncologic outcomes and improved perioperative outcomes. However, there is a paucity of data on long-term oncologic outcomes and concerns about a higher incidence of local recurrence after robot-assisted radical cystectomy.

Article Synopsis
  • - The study evaluated the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) surgical risk calculator's effectiveness in predicting outcomes for patients undergoing robot-assisted radical cystectomy (RARC) between 2005 and 2017 at a specific institute.
  • - After analyzing data from 462 patients, the actual complication rates were found to be significantly higher than the rates predicted by the ACS NSQIP calculator, with observed complication rates at 48% compared to a predicted 29%.
  • - The results indicated that the ACS NSQIP calculator had low accuracy (with low AUC values and high Brier scores) for predicting various postoperative complications, suggesting the need for a more tailored and specific risk calculator for

Oncocytic neoplasms occur in several organs and are most commonly found in the thyroid, kidneys and salivary glands. Oncocytic neoplasms of the adrenal cortex are extremely rare and are usually non-functioning, benign and incidentally detected. However, histologically, they are characterized by cells with eosinophilic granular cytoplasm and numerous packed mitochondria.

As cesarean sections become a more common mode of delivery, they have become the most likely cause of vesicouterine fistula formation. The associated pathology with repeat cesarean deliveries may make repair of these fistulas difficult. Early robotic-surgery offers a 3-dimensional view of the operative field and allows for intricate movements necessary for complex suturing and dissection.
