“…In the latest controlled trials, percutaneous RFA and nephrectomy show comparable survival rates. Takaki et al compared percutaneous RFA with partial and radical nephrectomy, and reported 5-year cancer-specific survival rates of 100 % [4]. Turna et al also reported not significantly different cancer-specific survival rates between percutaneous RFA and partial nephrectomy (83.9 % vs. 100.0 %, respectively) but more cardiovascular complications in patients with long-term follow-up after nephrectomy [5].…”

“…We previously reported that radio frequency ablation (RFA) was suitable as an optimal ordinary option for small renal nodules [10]. However in the current report, ordinary treatment options also included active surveillance, partial nephrectomy, and radical nephrectomy, but did not include ablation.…”

Objective: To assess the incidence and predictive factors of benign renal lesions in surgical specimens obtained at our institution. Methods: We carried out a retrospective assessment of 96 renal nodules, diagnosed by dynamic multi-detector row helical computed tomography, and resected by either radical or partial nephrectomy between January 2004 and November 2011. The incidence of benign lesions in 1-cm increments of diameter was determined and the predictive factors for these lesions were then evaluated. Results: Of the 96 nodules, histology confirmed that 13 (13.5%) were benign. The incidence of benign lesions was 25.0% for nodules <1 cm, 23.8% for nodules 1-1.9 cm, 11.5% for nodules 2-2.9 cm, 7.7% for nodules 3-3.9 cm, and 7.1% for nodules ≥4 cm. Multivariate analysis showed that younger age (<60 years; odds ratio [OR] = 5.23), female gender (OR = 4.78), and smaller nodule size (<3 cm; OR = 6.14) were significant predictive factors for benign lesions. Conclusions: The incidence of benign lesions in this study (13.5% of total cases) was relatively low compared with recent studies from Western countries that reported an incidence of 15-20%. Significant predictive factors for benign lesions included younger age, female gender, and smaller tumor size.

“…Olweny et al [28] identified no significant difference between RFA and open partial nephrectomy for the treatment of T1a RCC in terms of 5-year disease-free survival, metastasis-free survival and local recurrence. RFA causes less deterioration of renal function than partial nephrectomy with similar oncological outcomes [29,30,31,32]. Psutka et al [33] in a study of 185 patients with Stage I renal tumour reported a 5-year recurrence-free survival of 96.1%.…”

Purpose: Varicocele (abnormal dilatation of the pampiniform plexus secondary to a defect in the venous renospermatic system) is a relatively common condition, affecting 8-23% of young healthy males (1). Though often benign, it may create problems (significant pain in 14% or male factor infertility) that warrant intervention (1). Options for treatment are broadly classified into surgical or radiological (2). We aimed to determine the efficacy of radiological embolisation for the treatment of varicoceles by a single interventional radiology unit. Materials and methods: A retrospective review of all varicocele embolisation procedures performed by the interventional radiology unit at Austin Hospital (Melbourne) for the period of July 2005 to June 2015 was performed. Records and details (demographics, side, indication, duration, length of coil, complications) were obtained from electronic databases. Follow-up data was collected from the referring urologists. Results: A total of 131 varicocele embolisation procedures were performed. The majority of patients 105/131 (80%) were less than 40 years of age. Major indications were symptomatic pain (69%) or subfertility (10%). Laterality was 127/131 (97%) for left and 4/131 (3.1%) for bilateral varicoceles. Total coil length ranged from 18 to 38 mm. Procedure lengths averaged at 45mins. Complication rate was 6.1%, and mostly minor and not resulting in procedural abandonment. Complete follow-up data was obtained for 83patients only. Of these, recurrence occurred in only five patients (6.0%). Conclusions: Our study demonstrates that radiological embolisation is an effective modality for the treatment of varicoceles. Our single centre experience demonstrates comparable complication and recurrence rates of radiological embolisation versus the surgical treatment options (3). Given radiological embolisation is a day procedure with a reasonably short procedure time; our findings make it an effective option comparable to surgery. Objective / Introduction: Radiography of the immature skeleton is complex for junior doctors and students due to physes and ossification centers. Knowledge of normal radiographic characteristics is important to interpretation, which form the majority of xray studies of the paediatric population. Books and image based resources such as Keats Atlas of Normal Variants are cumbersome as an introductory resource, and a video/timelapse approach to normal skeletal development would condense the knowledge to a more accessible form. Project objective is to improve JMO proficiency in reading paediatric radiographs, including familiarity with the order of appearance of ossification centers, and improved fracture detection accuracy. Methods and materials:To demonstrate feasibility, a test timelapse was completed for the pelvis and proximal femur for 0-10 years of age. Anonymised radiographs were obtained from the local radiology department PACS. Images were aligned and stacked in a video editor, and annotated the order of appearance of ossification centres and physeal...

Midterm results of radiofrequency ablation versus nephrectomy for T1a renal cell carcinoma

Abstract: RF ablation provides RCC-related and DFS comparable to that found after nephrectomy with little loss of renal function.
