Objectives: The microbubbles enhanced ultrasound contrast is a novel technique that informs us in real time of renal perfusion and microcirculation.
Method: We reviewed the literature about its use in the study of renal masses in order to show their actual clinical performance in this condition.
Result: This technique is useful in the differential diagnosis of pseudotumors, characterization and monitoring of small renal masses, the study of complex renal cysts and controlling the progression of renal masses that underwent ablative treatments. Like any diagnostic technique has some limitations on usage;its rapid contrast wash, being operator-dependent, require some experience and need special software to be correctly interpreted.
Conclusions: The microbubbles enhanced ultrasound contrast is a useful and economic technique for the study and differential diagnosis of the renal masses.

Predicting Bleeding Related Events in Robotic-Assisted Partial Nephrectomy for Angiomyolipoma: Simplifying Risk Assessment with Tumor Diameter and Depth, A Retrospective Study.

Background: Evaluating risk factors for bleeding events in robot-assisted partial nephrectomy (RAPN) for renal angiomyolipoma (RAML) is essential for improving surgical outcomes.
Methods: We performed a retrospective analysis of patients who underwent RAPN for renal masses between May 2019 and June 2023 at a single medical center, categorizing them into AML and non-AML groups. We assessed demographic data, perioperative complications, and postoperative outcomes.

A 13-year-old boy was referred to orthopedic surgery for chronic intermittent pain and swelling of the left knee. Initial imaging was consistent with osteochondritis dissecans of the femoral condyle. Follow-up imaging demonstrated unexpected progression, with a mass extending into the notch, replacing the anterior cruciate ligament, and eroding the femoral and tibial condyles.

Article Synopsis
- The RENAL nephrometry score (RNS) is a method for assessing the complexity of kidney tumors, but it doesn't effectively predict outcomes after surgery.
- A modified version of the RENAL score was evaluated for its ability to forecast perioperative complications in patients undergoing open partial nephrectomy for small renal masses.
- The study included 47 patients, finding that the modified RENAL score is a useful indicator for predicting surgical risks, with a cut-off score of 8.7 linked to a higher likelihood of complications.

In patients with renal masses, when intervention is warranted, partial nephrectomy is preferred when feasible, especially for T1 renal masses. Thermal ablation, however, has become an accepted alternative treatment of small renal neoplasms with excellent oncologic outcomes. The National Comprehensive Cancer Network guidelines include thermal ablation as a treatment strategy for managing T1a and select T1b masses.

Objective: To improve the predictability of outcomes in robotic-assisted partial nephrectomy, we utilized three-dimensional virtual imaging for SPARE nephrometry scoring. We compared this method with a conventional two-dimensional scoring system to determine whether 3D virtual images offer enhanced predictive accuracy for Tetrafecta outcomes.
Methods: We retrospectively collected basic information, demographic data, and perioperative indices from patients who underwent robot-assisted partial nephrectomy for renal masses at the Department of Urology, First Affiliated Hospital of Xi'an Jiaotong University.
