Background
The incidence of renal cell carcinoma (RCC) is rising, in part because of greater use of cross-sectional imaging and the resultant detection of incidental, small renal masses [1]. Some 20% of renal masses of <4 cm in diameter are benign [2] and renal tumour biopsy (RTB) can better characterise the nature of such lesions and help in determining appropriate management [3]. Patients with small renal masses who have biopsy-proven RCC may be offered surgery, ablative therapy (cryoablation or
Discussion
This study represents the largest reported series of RTB tract seeding in which the cases were confirmed on histological examination of the resection specimen. In the modern literature, six cases of histologically proven RTB tract seeding have been reported (Table 3) [7], [8], [9], [10], [11], [12], one of which was associated with histologically proven local recurrences within the biopsy tract, abdominal wall, and psoas muscle [12]. The majority of these cases were also PRCC, although the RCC

2022, Progres en UrologieRenal tumor biopsy does not increase the risk of surgical complications of minimally invasive partial nephrectomy
2022, Progres en UrologieCitation Excerpt :The most common complications are renal hematoma (4.9%), clinically significant pain (1.2%), gross hematuria (1.0%), pneumothorax (0.6%) and hemorrhage requiring transfusion (0.4%). Tumor seeding along the needle tract has been considered anecdotal, especially when using coaxial technique [5,6,11–13]. A recent study showed that benign findings at pathology is significantly lower in centres where biopsies are performed (5% vs. 16%), suggesting that biopsies can reduce unnecessary surgery for benign tumors and therefore the morbidity associated with these procedures [14].
A unique case of chromophobe renal cell carcinoma seeding after biopsy
2022, Urology Case ReportsCitation Excerpt :Current guidelines and studies from centers of excellence suggest performing RTB to characterize the histology of radiologically indeterminate small renal lesions. Although rare and still mainly anecdotal, the increasing utilization of RTB to characterize SRMs has the potential to increase the occurrence of malignant tumor seeding of the biopsy tract.1 Macklin et al. reported on the largest series of histopathological tumour seeding with seven cases (1.2%) of all patients that underwent RTB before surgery, of which one developed local recurrence.1

2021, European Urology Open ScienceCitation Excerpt :As might be expected, patients in our study with cystic tumors and anterior tumors were less likely to undergo RMB. Other reports have shown lower diagnostic rates for cystic RMs (83.6% vs 99.1%) [2,23] and there is controversy regarding the appropriateness of RMB for cystic tumors given the inherent challenges of adequate tumor sampling and some concerns regarding tumor spillage [24–26]. RMB might be less likely for anterior tumors because of closer proximity to the bowel and visceral organs and a perceived risk of injury.
