Radiofrequency ablation of small renal cortical tumours in healthy adults: renal function preservation and intermediate oncological outcome

Myelomeningocele (MMC) is congenital nervous system malformation caused by neurulation process failure during pregnancy. The prevalence varies by the continent, region, race, ethnicity and the time when assessed and patients present abnormalities of different organs. One of the most severe complications is renal failure. Aim: Clinical evaluation of patients with MMC in Iraq and answering the question whether our treatment methods lead to renal function preservation. Material and methods: Medical records of 28 patients in the period 2014.2019were evaluated retrospectively. The data included: age, sex, BMI Z-score WHO, place of residence, perinatal history, social situation, physical activity, urodynamic diagnosis, renal function, hydrocephalus diagnosis, and functioning of shunting procedures. Results: They were no statistically significant differences in most studied parameters between boys and girls. Keywords: Meningomyelocele, Epidemiological study, Neurogenic bladder, Renal function

The Impact

Background: Radiographic characteristics may be associated withthe degree of renal function preservation following partial nephrectomy.The purpose of this study was to determine the impact ofpreoperative radiographic variables on change in renal functionusing 24-hour urine creatinine clearance (uCrCl).Methods: Patients with partial nephrectomy performed fromNovember 2003 to 2008 were enrolled in the study. Serum creatinineand 24-hour urine was collected preoperatively and at3, 6 and 12 months postoperatively. Computed tomography ormagnetic resonance imaging was used to determine tumour size,tumour location and renal volume.Results: Of the 36 patients, median age was 62 (range 30-78) and21 (58%) were male. The mean tumour diameter was 2.8±1.4 cm.Twenty-two (61%) tumours were located at the renal pole and11 (31%) were endophytic. Overall, mean preoperative uCrClwas 88.8±34.2 mL/min and mean postoperative uCrCl was82.8±33.6 mL/min (6.8%; p < 0.01). On multivariable analysis,no single characteristic was associated with a clinically prohibitivedecrease in renal function (-9.4% if endophitic, p = 0.06; -0.57%per cm diameter, p = 0.73; and -6.9% if located at the renal pole,p = 0.15). The total renal volume was also not significantly associatedwith renal function change (-1.1% per 100 cc, p = 0.86).Interpretation: Preoperative radiographic characteristics seem tobe associated with small changes in renal function following partialnephrectomy. These data support renal functional benefits of partialnephrectomy regardless of tumour size and location.

Robotic Assisted Partial Nephrectomy

Over the past few years, the role of robotic-assisted partial nephrectomy (RPN) has exponentially grown. Multiple recognized factors contribute to postoperative renal function in patients undergoing RPN. The aim of this review is to identify these potential factors, and to evaluate strategies that may help optimize the goal of renal function preservation. A nonsystematic literature review was performed to retrieve the most recent evidence on factors contributing to renal function post-RPN. Analyzed elements include baseline factors (tumor complexity and patient characteristics), intraoperative (surgical) factors (control of the renal hilum and type of ischemia, resection technique, renorrhaphy technique), and pharmacotherapeutics. In conclusion, the advantages of robotic surgery in the setting of partial nephrectomy (PN) are becoming well established. Maximal preservation of renal function remains a priority goal of the procedure, and it is influenced by a plethora of factors. Adequate patient selection using radiomics, control of comorbidities, utilization of evidence-based intraoperative techniques/strategies, and postoperative care are key components of postoperative preservation of renal function. Further investigations regarding these factors and their effects on long-term renal function are necessary and will continue to aid in guiding appropriate patient care.
