“…A similar observation has been reported by other authors using needles of identical gauges [5]. The adequacy of the biopsy material also compared favorably with other reports in the literature [6,7,12] regardless of the technique used [5,13].…”

Objective: Ultrasound-guided core renal biopsies were performed in children to describe the accuracy of this technique and compare it with the other techniques. Methods: Forty-six children, aged 9 months to 13 years, were biopsied with 14 G and 18 G Tru-cut needles, using a real-time ultrasound sector scanner. Results: Adequate biopsy samples were obtained from 88.2 and 86.9% of the biopsy procedures with 14 G and 18 G Tru-cut needles, respectively. No major complications were encountered. Minor complications were also minimal and seen in only 3 of our patients who were managed conservatively. Conclusion: Ultrasound-guided Tru-cut renal biopsy is a safe and efficient method for performing renal biopsies in pediatric patients. The use of small needles (18 G) would reduce the complication rate while allowing retrieval of sufficient tissue for histological diagnosis.

“…There was a slightly larger proportion of complications using microbiopsy forceps, but it was not statistically significant [28]. There is paucity of studies focusing on the needle size, which is in contrast to studies in biopsies of other organs [29,30,31,32,33,34]. …”

Aim: To compare the risk of postoperative haemorrhage with different sizes of brain biopsy needles. Patients and Method: A cohort of patients using a 2.5-mm outer diameter side-cutting biopsy needle was compared to a subsequent cohort using a 1.8-mm needle of the same type. All data were collected prospectively. A CT scan was done within 12 h after surgery. Any visible haemorrhage at the operated site was documented. Results: From 2007 to 2013, 54 stereotactic brain biopsies (all frameless except for one frame-based) were performed. The 2.5-mm group comprised 29 procedures from 2007 to 2009. The 1.8-mm group comprised the subsequent 25 procedures. The diagnostic yields were 90 and 96% in the 2.5- and the 1.8-mm group, respectively (p = 0.615). Comparing the 2.5- and the 1.8-mm group, haemorrhage was significantly reduced: incidence (72 vs. 40%, p = 0.016); size of haemorrhage (mean 7.2 vs. 2.6 mm, p = 0.002); proportion of haemorrhage size >10 mm (34.5 vs. 4%, p = 0.006). Symptomatic haemorrhage rates were 3.4 and 0.0% in the 2.5- and the 1.8-mm group, respectively (p = 1.00). Conclusion: The 1.8-mm outer diameter needle carried a lower risk of postoperative haemorrhage than the 2.5-mm one, without compromising the diagnostic yield.

“…However, Wood et al [18] suggested that core biopsy and FNA are complementary and the combination of these techniques was better then either alone. Although complications are rare, it has been FNA CYTOLOGY FOR RENAL MASSES 15 shown that there is a lower complication rate when using ®ner needles for core biopsy [20], but this difference is not as clearly established in the kidney as it is for the liver. Theoretically therefore, FNA is probably a safer method of biopsy than needle-core biopsy, yet comparable in sensitivity.…”

Evaluation of fine‐needle aspiration cytology for renal masses

Objective To evaluate the accuracy and use of ®ne-needle aspiration (FNA) cytology for the diagnosis of renal masses because with the improved quality and increasing use of ultrasonography and computed tomography (CT), asymptomatic renal masses, particularly small (<5 cm) tumours, are being discovered more frequently. Patients and methods Between 1995 and 1997, 49 patients (mean age 67.5 years, range 42±88, 34 men and 14 women) underwent FNA of a solid or complex cystic mass under radiological guidance. All masses were further evaluated and staged by CT. Solid masses were divided according to size (<5 cm and o5 cm).Patients were followed up to the determination of a ®nal diagnosis on tissue histology, after nephrectomy where possible. Results Thirty-six patients had histologically con®rmed carcinoma at nephrectomy, and nine had presumed carcinoma (four un®t for surgery, ®ve with advanced malignancy). The remaining four patients had benign diagnoses. FNA produced insuf®cient sample in eight cases (16%). The sensitivity was 89% for large (o5 cm) solid masses, 64% for small (<5 cm) solid masses and 50% for complex cysts. Conclusion FNA does not contribute to the diagnosis of malignancy in large (>5 cm) masses, as good radiological imaging is nearly always diagnostic. For smaller (<5 cm) masses and complex cysts, FNA can occasionally con®rm malignancy, but lack of diagnostic yield and low sensitivity means that FNA is unreliable as a diagnostic tool and will rarely help in the routine management of these patients.
