Background And Objectives: "Trifecta" in partial nephrectomy consists of negative surgical margins, minimal renal function decrease and absence of complications. In the present article, our single-center robot-assisted partial nephrectomy (RAPN) experience in T1b renal masses is reported in terms of strict Trifecta outcomes.
Methods: This is a retrospective analysis of patients with a tumor diameter between 4 and 7 cm (stage T1b), who underwent RAPN by a single surgeon. Preoperative, intraoperative, and postoperative data were recorded and analyzed to evaluate short-term functional and oncologic outcomes. Patients with absence of grade ≥ 2 Clavien-Dindo complications, warm ischemia time (WIT) ≤25 minutes, ≤15% postoperative estimated glomerular filtration rate (eGFR) decrease and negative surgical margins were reported to achieve strict Trifecta outcomes. < .05 was indicated statistically significant.
Results: A total of 150 patients underwent RAPN, and 50 patients were identified with tumor size between 4 and 7 cm. Mean WIT was 20.8 ± 6.2 minutes and mean estimated blood loss (EBL) was 269 ± 191 mL. Surgical margins were negative in all patients. Eleven patients (22%) had a >15% eGFR decrease after surgery. Nine patients (18%) had WIT longer than 25 minutes. Four patients (8%) had grade ≥2 Clavien-Dindo complications. Twenty-nine (58%) patients had strict Trifecta outcomes. Mean follow-up was 44.2 ± 27.2 months. Tumor recurrence was not observed in any patient.
Conclusions: Robot-assisted laparoscopic partial nephrectomy for T1b renal masses can be safely performed in experienced hands. Optimal strict Trifecta outcomes and recurrence rates can be achieved.

Purpose: Evaluation of a kidney-adjusted enhanced recovery after surgery (ERAS) protocol (kERAS) in patients undergoing nephron-sparing surgery (PN).
Methods: The kERAS protocol is a multidimensional protocol focusing on optimized perioperative fluid and nutrition management as well as strict intraoperative and postoperative blood pressure limits. It was applied in a prospective cohort (n = 147) of patients undergoing open or robotic PN.

Patients And Methods: Patients were eligible for randomisation if they had a diagnostic transurethral resection of bladder tumour with clinical T stage (cT)2-4, cN0, cM0, or recurrent high-grade non-muscle-invasive bladder cancer and no anaesthesia contraindications to robotic surgery. Patients were enrolled with a covariate adaptive randomisation process based on the following variables: body mass index, American Society of Anesthesiologists score, preoperative haemoglobin, planned UD, neoadjuvant chemotherapy, and cT stage.

Background: Partial nephrectomy (PN) is the gold standard surgical treatment for resectable renal cell carcinoma (RCC) tumors. However, the decision whether a robotic (RAPN) or open PN (OPN) approach is chosen is often based on the surgeon's individual experience and preference. To overcome the inherent selection bias when comparing peri- and postoperative outcomes of RAPN vs.

Article Synopsis
- The study evaluates the effectiveness and safety of Percutaneous Cryoablation (PCA) for small renal masses (SRMs) in patients unsuitable for surgery, analyzing data from four centers over a 10-year period.
- Patients were categorized based on the size of their masses into two groups, with results indicating a significantly higher success rate (Trifecta outcomes) in smaller masses compared to larger ones, and a notable increase in complications for the larger group.
- Overall, PCA shows promise as a safe and effective treatment, but suggests that stricter size limits may improve success rates for managing SRMs.

Vascular disease was for a long time considered a disease of the old age, but it is becoming increasingly clear that a cumulus of factors can cause early vascular aging (EVA). Inflammation plays a key role in vascular stiffening and also in other pathologies that induce vascular damage. There is a known and confirmed connection between inflammation and atherosclerosis.
