The objective of this study was to evaluate the early surgical outcomes of robot-assisted partial nephrectomy (RAPN) for small renal masses in a large Japanese multicenter series.

A total of 804 consecutive cases of RAPN were examined at 42 institutes between 2011 and 2016.

Kidney cancer (mostly renal cell carcinoma) is one of the ten most commonly diagnosed malignant tumors among men and women. Due to the widespread use of computer tomography and magnetic resonance imaging, the proportion of early-stage kidney cancers has increased.

Robot-assisted partial nephrectomy (RAPN) has become widely used for treatment of renal cell carcinoma and it is expanding in the field of complex renal masses. The aim of this systematic review was to analyze outcomes of RAPN for completely endophytic renal masses, large tumors (cT2-T3), renal cell carcinoma in solitary kidney, recurrent tumors, completely endophytic and hilar masses, and simultaneous and multiple tumors.

While several recent studies investigated the influence of statins on survival outcomes in prostate cancer (PCa) patients on androgen deprivation therapy (ADT), definitive conclusions are still missing.

 BERKELEY, CA (UroToday.com) - Partial nephrectomy has shown both improved overall patient survival and more effective preservation of renal function, when compared with radical nephrectomy.

Advances in imaging technologies have increased the opportunities for treating small-diameter renal cell carcinomas (RCCs) in the elderly. This retrospective study based on real-world clinical practice compared perioperative complications, preoperative and postoperative renal function, recurrence-free survival, and overall survival in elderly patients with RCC who had undergone robot-assisted partial nephrectomy (RAPN) or percutaneous cryoablation (PCA).

We aimed to report the latest and largest pooled analysis and evidence update to compare the perioperative, renal functional, and oncological outcomes between off-clamp and on-clamp robot-assisted partial nephrectomy (RAPN) for renal tumors.

The study aims to assess the available literature and compare the perioperative outcomes of robotic-assisted partial nephrectomy (RAPN) for posterior-lateral renal tumors using transperitoneal (TP) and retroperitoneal (RP) approaches.

To provide further evidence supporting the effectiveness of RAPN in a contemporary patient population treated at one of three tertiary care centers for robotic surgery and to describe the evolution of RAPN-based technical improvements.

One of the most important steps of the partial nephrectomy (PN) is hemostatic control of tumor bed which also effects the warm ischemia time (WIT). Argon beam coagulation (ABC) for decades is a well-known method for surface controls during major open surgical sites.

Hugo™ RAS system is one of the most promising new robotic platforms introduced in the field of urology. To date, no data have been provided on robot-assisted partial nephrectomy (RAPN) performed with Hugo™ RAS system.

Hypertension (HTN) is a global public health issue. There are limited data regarding the effects of HTN in patients undergoing partial nephrectomy (PN) for renal tumors. To address this void, we tested the association between HTN and renal function after minimally invasive PN (MIPN).

To investigate the perioperative and morbidity outcomes after partial nephrectomy (PN) in patients with short life expectancy (SLE) (≥95% 10-year expected mortality (10y-EM)), to assess the main predictors of outcomes in this population and to compare these results with those of a group at the opposite upper range with long LE (LLE, ≤5% 10y-EM) relying on a multicenter Italian prospective registry of kidney surgery (the RECORD 2 project).

The use of a nephron-sparing surgery for the treatment of localized renal masses is being pushed to more challenging cases. However, this procedure is not devoid of risks, and the Radius, Exophytic/Endophytic, Nearness, Anterior/Posterior, Location (RENAL) and Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) classifications are commonly employed in the prediction of complications.

Three-dimensional (3D) models improve the comprehension of renal anatomy.

To evaluate the impact of novel 3D-derived parameters, to predict surgical outcomes after robot-assisted partial nephrectomy (RAPN).

RAPN training usually takes place in-vivo and methods vary across countries/institutions. No common system exists to objectively assess trainee capacity to perform RAPN at predetermined performance levels prior to in-vivo practice.

The debate on the pros and cons of robot-assisted partial nephrectomy performed with (on-clamp) or without (off-clamp) renal artery clamping is ongoing. The aim of this meta-analysis is to summarize the available evidence on the comparative studies assessing the outcomes of these two approaches.

On-clamp partial nephrectomy for the surgical treatment of renal masses poses the risk of ischemia and greater post-operative renal function loss. Conversely, the off-clamp technique might enhance renal function preservation by avoiding any ischemia time.

To retrospectively compare long-term oncologic outcomes of percutaneous computed tomography-guided microwave ablation (MWA) and robot-assisted partial nephrectomy (RAPN) for the treatment of stage 1 (T1a and T1b) renal cell carcinoma (RCC) patients.

Renal cell carcinoma (RCC) in solitary kidney (SK) represents a challenging scenario. We sought to compare outcomes of robot-assisted partial nephrectomy (RAPN) versus percutaneous thermal ablation (PTA) in SK patients with renal tumors cT1.

To compare the perioperative outcomes of patients with complex renal tumors treated with open versus robot-assisted partial nephrectomy.

This retrospective study included 273 patients diagnosed with localized renal tumors at our institution between January 2007 and October 2020.

To analyze the effects of laparoscopic partial nephrectomy (LPN) and robot-assisted partial nephrectomy (RAPN) for the treatment of renal cell carcinoma (RCC) on subsequent split renal function using renal scintigraphy.

Robot-assisted partial nephrectomy (RAPN) has gained increasing popularity as primary minimally invasive surgical treatment for localized renal tumors, and it has preferably been performed with a transperitoneal approach.

To assess the outcomes of retroperitoneal robot-assisted partial nephrectomy (r-RAPN) in a large cohort of patients with postero-lateral renal masses comparing to those of transperitoneal RAPN (t-RAPN).

Robot-assisted partial nephrectomy (RAPN) represents a widely accepted minimally invasive alternative to open and laparoscopic surgery for the treatment of clinically localized renal tumors.

To assess the feasibility of RAPN in a contemporary series of patients with highly complex tumors (PADUA score ≥10) treated at four high-volume robotic surgery institutions.

A hilar location for a renal tumour is sometimes viewed as a limiting factor for safe partial nephrectomy. Our aim was to evaluate perioperative, oncological, and functional outcomes of robot-assisted partial nephrectomy (RAPN) for hilar tumours (RAPN-H) in comparison to RAPN for nonhilar tumours (RAPN-NH).

BACKGROUND - We present the oncological and functional results from a series of 43 patients with renal tumours, treated consecutively with robot-assisted partial nephrectomy (RPN).

MATERIALS AND METHODS - Between 2010 and 2014, we performed 95 RPNs.

Our study aimed to compare the surgical outcomes of robot-assisted partial nephrectomy (RAPN) between younger and older patients after adjusting for their background differences. We particularly assessed RAPN outcomes and safety in older patients.

This study aimed to explore the appropriate location of renal tumors for retroperitoneal approach.

We retrospectively analyzed 1040 patients with renal tumor who were treated at our institution from Janurary 2015 to June 2020 and had underwent retroperitoneal robotic assisted-laparoscopic partial nephrectomy (rRAPN).

Partial nephrectomy (PN) for small renal masses is common, but outcomes are not reported in a standard manner. Traditionally, parameters such as 90-day mortality, blood loss, transfusion rates, length of stay, nephrometry scoring and complications are published but their collective impact on warm ischemia time (WIT) and post-surgery GFR is rarely determined.

Current literature does not provide large-scale data regarding clinical outcomes of robot-assisted (RAPN) versus open (OPN) partial nephrectomy. Moreover, data assessing predictors of long-term oncologic outcomes after RAPN are scarce.

Robot-assisted partial nephrectomy (RAPN) outcomes might be importantly affected by increasing surgical experience (EXP). The aim of the study is to investigate the effect of EXP on warm ischemia time (WIT), presence of at least one Clavien-Dindo ≥2 postoperative complication (CD ≥ 2), and positive surgical margins (PSMs) to define the learning curve for RAPN.
