Using the Vattikuti Collective quality initiative (VCQI) database for RAPN, data for morbidly obese and non-obese patients was obtained. Propensity scores were calculated for two treatment groups (morbidly obese vs.
View Article and Find Full Text PDFBackground: Partial nephrectomy is the preferred treatment option for the management of small renal masses. On-clamp partial nephrectomy is associated with a risk of ischemia and a greater loss of postoperative renal function, while the off-clamp procedure decreases the duration of renal ischemia, leading to better renal function preservation. However, the efficacy of the off- versus on-clamp partial nephrectomy for renal function preservation remains debatable.

The primary aim of this study was to report and evaluate the factors predicting trifecta and pentafecta outcomes following RAPN in Indian patients using the multicentric Vattikuti collective quality initiative (VCQI) database.
Methods: From the VCQI database for patients who underwent RAPN, data for Indian patients were extracted and analyzed for factors predicting the achievement of trifecta and pentafecta following RAPN.
Introduction: Outcomes of robot-assisted partial nephrectomy (RAPN) depend on tumor complexity, surgeon experience and patient profile among other variables. We aimed to study the perioperative outcomes of RAPN for patients with complex renal masses using the Vattikuti Collective Quality Initiative (VCQI) database that allowed evaluation of multinational data.
Methods: From the VCQI, we extracted data for all the patients who underwent RAPN with preoperative aspects and dimensions used for an anatomical (PADUA) score of ≥10.
Objective: To compare perioperative outcomes following robot-assisted partial nephrectomy (RAPN) in patients with age ≥ 70 years to age < 70 years.
Methods: Using Vattikuti Collective quality initiative (VCQI) database for RAPN we compared perioperative outcomes following RAPN between the two age groups. Primary outcome of the study was to compare trifecta outcomes between the two groups.
The technique of robotic kidney transplantation (RKT) under regional hypothermia is being described. It may be performed in all patients requiring kidney transplantation with some relative contraindications. Unlike open transplantation, RKT is a transperitoneal procedure.

Objective: To develop and internally validate a preoperative nomogram predicting IOAEs for robot-assisted PN (RAPN).
Design, Setting, And Participants: In this observational study, data for demographic, preoperative, and postoperative variables for patients who underwent RAPN were extracted from the Vattikuti Collective Quality Initiative (VCQI) database.
Objective: To compare perioperative outcomes following retroperitoneal robot-assisted partial nephrectomy (RPRAPN) and transperitoneal robot-assisted partial nephrectomy (TPRAPN).
Methods: With this Vattikuti Collective Quality Initiative (VCQI) database, study propensity scores were calculated according to the surgical access (TPRAPN and RPRAPN) for the following independent variables, i.e.
Aim: ABO-incompatible (ABOi) kidney transplantation overcomes immunological barrier of blood group incompatibility. There have been very few published experiences of ABOi kidney transplantation from India. We present our single-center experience of the first hundred ABOi kidney transplants.

The disparity between the availability of organs and waitlisted patients for transplants has forced many transplant centers across the world to use marginal kidney donors. We assess and compare postoperative estimated glomerular filtration rate (eGFR) in patients who received a graft from marginal renal donor (MRD) versus those who received a graft from standard renal donor (SRD).

Patient And Methods: We retrospectively reviewed a multinational database of 3802 adults who underwent RAPN for elective and imperative indications. Laparoscopic or open partial nephrectomy (PN) were excluded.
Introduction: Coronavirus disease 2019 (COVID-19) pandemic led to a sudden drop in renal transplant numbers across India in the initial months of 2020. Although the transplant numbers increased with easing of lockdown, the outcome of these transplants remains unknown.
Methods: This was a retrospective, observational, multi-center study done across eight different transplant centers in India.
The aim of the study was to report the perioperative and functional results of Robotic assisted kidney transplantation (RAKT) in Grafts with multiple vessels (GMVs) and compare it to the results of Open kidney transplantation (OKT) with GMVs. Patients undergoing RAKT from living donors using GMVs were reviewed from prospectively collected RAKT database at our institution between March 2013 and March 2018. Patient undergoing Open kidney transplantation (OKT) using GMVs served as controls.

Methods: We analyzed 1453 patients undergoing RPN, from 2006 to 2018, within a large multi-institutional database. Patients having surgery for bilateral tumors (n = 73) were excluded.
Purpose: We report on comparative effectiveness of minimally invasive versus traditional open kidney transplantation.
Materials And Methods: We undertook a prospective cohort study of 654 patients who underwent open or robotic kidney transplantation at a single tertiary care hospital between January 2013 and December 2015. Primary outcome was delayed graft function, defined as the need for dialysis within 1 week of surgery.

Objective: To predict intra-operative (IOEs) and postoperative events (POEs) consequential to the derailment of the ideal clinical course of patient recovery.
Materials And Methods: The Vattikuti Collective Quality Initiative is a multi-institutional dataset of patients who underwent robot-assisted partial nephectomy for kidney tumours. Machine-learning (ML) models were constructed to predict IOEs and POEs using logistic regression, random forest and neural networks.
Donor nephrectomy is an extremely challenging procedure. The stakes are high, as two lives-the donor and the recipient-depend on it. Robotic donor nephrectomy has an edge over a laparoscopic approach.
View Article and Find Full Text PDFObjectives: To evaluate retroperitoneal robot-assisted partial nephrectomy (RAPN) against transperitoneal approach in a multi-institutional prospective database, after accounting for potential selection bias that may affect this comparison.
Patients And Methods: Post-hoc analysis of the prospective arm of the Vattikuti Collective Quality Initiative database from 2014 to 2018. Six hundred and ninety consecutive patients underwent RAPN by 22 surgeons at 14 centers in 9 countries.
Purpose: Outcomes of surgical procedures can be affected by multiple factors including surgical skill and learning curve (LC). These factors need to be considered for optimal timing of surgical trials. We used the LC cumulative summation (CUSUM) method to describe the number of cases associated with competency of a single surgeon learning the technique of robotic kidney transplantation (RKT).

Methods: Between November 2014 and February 2017, 501 patients underwent attempted RAPN by 22 surgeons at 14 centers in 9 countries within the Vattikuti Collaborative Quality Initiative database. Patients were permanently logged for RAPN prior to surgery and were analyzed on an intention-to-treat basis.
We present our experience with robotic radical prostatectomy and analyse the predictors for extracapsular extension (EPE) in a cohort of Indian patients. Four hundred fifty-three patients underwent robotic radical prostatectomy from May 2010 to October 2015. Post hoc analysis of prospectively maintained data was done.
