Performing an early systematic Doppler-ultrasound fails to prevent hemorrhagic complications after complex partial nephrectomy.

Background: The aim of this work was to assess the clinical relevance of a systematic postoperative Doppler-ultrasound (DU) after complex partial nephrectomy (PN).

Materials And Methods: All patients who underwent open, laparoscopic or robotic PN from 2014 to 2017 at our institution were included. Postoperative hemorrhagic complications (HCs) were defined as the occurrence of blood transfusion, hemorrhagic shock, arterial embolization, or re-hospitalization for hematoma.

Nephron sparing surgery in tumours greater than 7cm.

Introduction: Partial nephrectomy (PN) is the gold standard treatment for renal cell carcinomas under 4cm. No robust data exists to recommend PN for tumours>7cm (cT2). The objective of this work is to evaluate the results of PN for cT2 tumours.

[Comparison of operative and oncologic results between partial nephrectomy and radiofrequency ablation for treatment of renal tumors in patients older than 75].

Introduction: Elderly patients represent a growing part of our society for who treatment strategy for localized renal tumors has to be chosen knowing iatrogen effects and renal function morbidity. The aim was to analyze oncological and functional results of nephron sparing surgery (PN) versus radiofrequency ablation (RFA).

Materials And Methods: All patients aged more than 75 treated by partial nephrectomy or radiofrequency ablation between 2007 and 2014 in our centre were included.

Pathological heterogeneity in sporadic synchronous renal tumors: Is the histological concordance predictable?

Objective: To evaluate the pathological concordance rate of multiple synchronous renal masses (MSRM) presumed to be sporadic and to analyze predictive factors of concordance.

Material And Methods: We identified from our institutional database patients with sporadic MSRM treated at our center between January 2000 and December 2015. All tumors were reviewed by a dedicated uropathologist.

Prospective assessment and histological analysis of adherent perinephric fat in partial nephrectomies.

Objectives: The complexity of partial nephrectomy (PN) is partly anticipated by morphometric tumor-based scores that do not consider patient-related issues such as adherent perinephric fat (APF). Also, the objective is to prospectively assess the predictive factors of APF during PN, its effect on complications, and to correlate it to the histological reality.

Methods: A total of 125 consecutive patients undergoing robotic or open PN were prospectively included.
