Objective: The aim of the study is to evaluate the effect of deferred androgen deprivation therapy on biochemical recurrence (BCR) and other survival parameters in node-positive prostate cancer patients after robot-assisted radical prostatectomy with bilateral extended pelvic lymph node dissection (RARP + EPLND).

Materials And Methods: Of the 453 consecutive RARP procedures performed from 2011 to 2018, 100 patients with no prior use of androgen deprivation therapy were found to be lymph node (LN) positive and were observed, with initiation of salvage treatment at the time of BCR only. Patients were divided into 1 or 2 LNs (67)-and more than 2 LNs (33)-positive groups to assess survival outcomes.

Background: The presence of adverse pathological features like extraprostatic extension, seminal vesicle involvement, or positive margins at radical prostatectomy incurs a high risk of postoperative recurrence. Currently, adjuvant radiotherapy (ART) is the standard of care in these patients, while early salvage radiotherapy (eSRT) is a potential alternative strategy.

Aims: The purpose of this paper is to review the latest evidence comparing outcomes of adjuvant versus early SRT in this clinical scenario.

Robot-assisted radical prostatectomy (RARP) is challenging in men with prior history of transurethral resection of the prostate (TURP). Few studies analyze this peculiar group of patients, and hence we sought to investigate the outcome of RARP in post-TURP men. We interrogated our prospectively maintained database containing 643 patients who underwent RARP from January 2012 to December 2020.

Older men undergoing robot-assisted radical prostatectomy (RARP) have been thought to have worse perioperative, functional and oncological outcomes than younger men. However, there is a dearth of matched studies on this subject in the currently available literature. Our study is a matched pair analysis of perioperative, oncological and functional outcomes of RARP in men < 75 years of age versus ≥ 75 years (62 in each group).

Introduction And Objective: Carcinoma prostate is considered highly aggressive in Asian countries such as India. This raises an argument whether active surveillance (AS) gives a false sense of security as opposed to upfront radical prostatectomy (RP) in Indian males with low-risk prostate cancer (PCa). We analyzed our prospectively maintained robot-assisted RP (RARP) database to address this question.

Introduction:: Surgical technique for robotic approach to inguinal lymphadenectomy (R-VEIL) has been adapted and evolved over last few years.

Materials And Methods:: We use PDB 1000 balloon® for creation of space below Scarpa's fascia (similar to retroperitoneoscopy). Our approach to lymphadenectomy is “roof first, floor later approach” with separate removal of superficial and deep inguinal lymph node packets, prior to and after opening fascia Lata.

Introduction: Total pelvic exenteration with permanent fecal and urinary diversion is a rare, extensive and morbid surgical procedure reserved for locally advanced soft tissue tumors arising in the pelvis. A robot assisted approach with intracorporeal diversion has the potential advantage of decreasing the morbidity of this procedure, but has not been well described in literature.

Materials And Methods: Using a da Vinci Xi® system, robot assisted total pelvic exenteration with intracorporeal diversion was performed in a 49 year old gentleman with a 13.

Objective: To evaluate the clinical and financial implications of a decade of prostate biopsies performed in the UK National Health Service (NHS) through the transrectal (TR) vs the transperineal (TP) route.

Methods: We conducted an evaluation of the TR vs the TP biopsy approach in the context of 28 days post-procedure complications and readmissions. A secondary evaluation of burden of expenditure in NHS hospitals over the entire decade (2008-2019) was conducted through examination of national Hospital Episode Statistics (HES) data.

Introduction: The objective of this study was to evaluate the perioperative outcomes of patients undergoing robot-assisted radical cystectomy (RARC) with intracorporeal ileal conduit (IIC) urinary diversion treated in line with the enhanced recovery after surgery (ERAS) protocol.

Methods: After approval from the institutional ethics committee, we conducted an analysis of a prospectively maintained database of patients undergoing RARC + IIC using ERAS protocol by a single surgical team with the da Vinci Xi system from March 2016 till December 2018. To minimize the effect of the learning curve of this complex procedure, we excluded the first thirty patients from analysis.

Posterior hilar renal tumor extirpation by partial nephrectomy is a unique challenge for transperitoneal laparoscopy. We describe our novel technique of "polar flip" for these tumors. Kidney is rotated by around 45 -60 degrees after mobilisation so that lower pole faces anteriorly and upper pole faces posteriorly, thereby exposing the posterior surface for maneuverability.

Context And Aim: About 1% of the patients undergoing percutaneous nephrolithotomy (PCNL) have bleeding severe enough to require angioembolization. We identified factors which could predict severe bleeding post-PCNL and reviewed patients who underwent angioembolization for the same.

Settings And Design: This is a single-institutional, retrospective study over a period of 3 years.

Introduction: In the current era, every broad specialty has diversified into many subspecialties including urology, which is one of the most dynamic fields. The concept of early sub-specialization relies on excelling in a niche area of interest. While this concept is appealing to the most, no formal evaluation of our residency programs has ever been conducted with regard to their adequacy in terms of equipping residents to make informed sub-specialization choices.

Retroperitoneal lymph node dissection (RPLND) is a therapeutic standard of care for post-chemotherapy residual masses in testicular cancer. While a robotic approach to this procedure has the potential of decreasing the morbidity associated with this major endeavour, it is often criticised for its inability to provide a bilateral complete template resection without redocking and repositioning the patient. Herein, we present the technique and initial outcomes of a supine approach to Robotic RPLND (R-RPLND) using the da Vinci Xi system, which obviates the need for repositioning or redocking for a bilateral full template resection.

Though the overall safety of laparoscopic nephrectomy (simple or radical) is well established, for a novice it remains a challenge. The classical description of laparoscopic nephrectomy entails dissection either from caudal to cephalad side or vice versa. Herein we describe our "two window technique" for managing renal hilum during laparoscopic (simple/radical) nephrectomy.

While pelvic lymphadenectomy during radical cystectomy for bladder cancer is a well-established standard of care, the same does not hold true for upper tract urothelial carcinoma (UTUC). Indeed, a template-based lymphadenectomy is rarely, if ever, performed in conjunction with radical nephroureterectomy at most centres across the globe. While multiple studies have explored the staging and therapeutic role of lymphadenectomy in cases of UTUC, there remain large gaps in our understanding of the indications, extent and safety of this procedure as an adjunct to nephroureterectomy.

Introduction: Robot-assisted radical nephroureterectomy (RANU) with extended template lymphadenectomy (E-LND) is the leading treatment option for nonmetastatic upper tract urothelial carcinoma. Due to the rarity of this disease, there is a lack of consensus regarding the best approach and the extent of lymphadenectomy. We report our technique and its initial outcomes from the retrospective evaluation of a prospectively maintained database of 11 consecutive cases of RANU + E-LND.

Objective: To evaluate the perioperative outcomes and 90-day complication rates of continuation of low-dose aspirin through surgery in patients undergoing robot-assisted radical prostatectomy (RARP). A significant proportion of patients undergoing RARP are on antiplatelet medications for primary or secondary prevention of cardiovascular events. However, there is still a relative lack of data with regard to the advantages and complications of continuing these medications through surgery.

Aims: There has been much speculation and discussion about the infective complications of percutaneous nephrolithotomy (PCNL). While fever is common after PCNL, the incidence of it progressing to urosepsis is fortunately less. Which patient undergoing PCNL is at risk of developing urosepsis and in whom aggressive treatment of fever postoperatively may prevent the progression to severe sepsis becomes a very important question.
