“…The number of glomeruli per biopsy was significantly less with the 18-gauge needle (9 glomeruli) compared to that obtained with the 14- or 16-gauge needles (12 glomeruli each, p < 0.001), and the adequacy rate was lower at 94.3%. A number of studies have shown that the diagnostic yield is greater with 14-gauge automated needles compared to 16- or 18-gauge needles, and the quality of the sample has been shown to be superior, with more ‘intact' glomeruli and less ‘crush or fragmentation' artifact [3,8,11,21,29,32,33,34,35,36,37,38]. In the only prospective study assessing the differences between automated needle sizes, Nicholson et al [37] demonstrated that the use of a 14-gauge needle resulted not only in a significantly larger sample size (15 vs. 11 vs. 9 glomeruli, p < 0.05) but also greater diagnostic success (85 vs. 76 vs. 53%, p < 0.05) compared to the use of 16- or 18-gauge needles.…”

Background: Percutaneous renal biopsy (PRB) of native kidneys is an essential tool in the diagnosis and management of renal disease. We report one of the largest single-center experiences on the success and safety of the procedure. Methods: From June 1983 to March 2012, 1,055 adults underwent PRB using real-time ultrasound guidance and 14-gauge biopsy needles. Data were collected prospectively for 826 biopsies (78%). Statistical analysis was performed using the Mann-Whitney test, Wilcoxon matched pairs test and Kruskal-Wallis test for continuous data or the Fisher's exact test and χ² test for categorical data. Multivariate analysis using logistic regression was performed to determine which feature at baseline was predictive of a complication following renal biopsy. Results: Patients were aged 46 ± 17 years; 38% were male, 40% were white and 43% were African-American. Serum creatinine (SCr) was 2.3 ± 2.3 mg/dl (>1.5 mg/dl in 47%). The pre-PRB hemoglobin was 12 ± 2 g/dl (<11.0 g/dl in 35%). Adequate tissue for diagnosis was obtained in 99% of biopsies. Minor complications occurred in 8.1% of biopsies (mainly gross hematuria, in 4.5%). Major complications occurred in 6.6% of biopsies, with transfusions required in 5.3%. Only 1 death (0.09%) resulted from post-PRB bleeding. By multivariate analysis, baseline features predictive of a complication were systolic blood pressure >170 mm Hg (OR 4.2, 95% CI 1.8-9.8), bleeding time >7.5 min (OR 1.7, CI 1.2-2.5) and SCr >3.5 mg/dl (OR 1.8, CI 1.2-2.9). Conclusions: PRB of native kidneys using real-time ultrasound with a 14-gauge automated needle remains a successful and safe procedure.

“…The laparoscopic biopsy offered the ability to the direct visualization of the pathologic condition of the horse (Fischer). Excellent-quality renal biopsy specimens with large numbers of glomeruli can be obtained during laparoscopy versus ultrasound guidance (Rawlings et al, 2003). The learning curve for the ultrasound-guided procedure was steeper than that for laparoscopic biopsy (Cole et al, 2002).…”

Gasless Laparoscopic Anatomy and Renal Biopsy of the Kidney in the Standing Mare

et al. 2014

SUMMARY:The current study aimed to provide the topography and renal biopsy of the standing mare kidneys by laparoscopy w ithout CO 2 insufflation and to compare between the use of biopsy needle and forceps. Five clinically healthy adult nonpregnant mares weighing 250-300 Kg and aging 7-9 years were used in the current work. The gasless laparoscopic renal biopsy appeared simple, safe, reliable, minimal invasive, timesaving and economical technique. The parallel biopsy portals provided easy and accessible biopsy procedure than dorsal or ventral portals. The biopsies taken from the lateral surface were less hemorrhagic than those taken from the caudal pole. This study recommended the laparoscopic forceps because the biopsy forceps provided satisfactory and representative specimens with minimal hemorrhage than Tru-cut needle.

“…The most common complication was hemorrhage. There have been a number of recent published reviews comparing renal biopsy methods to optimize specimen procurement and minimize biopsy-induced complications (Rawlings et al, 2003;Rawlings and Howerth, 2004;Vaden, 2004Vaden, , 2005Vaden et al, 2005).…”
