Abstract Aim: The study aims to compare the adequacy, complication and pathological classification rates of using 18G vs. 16G needles to perform renal biopsy with ultrasound-guided on native kidneys in Chinese. Methods: We retrospectively analyzed the number of glomeruli, adequate sample rates, complication rates and pathological classification in 270 patients who were used by 18G or 16G needles separately from January, 2011 to May, 2017，and verified whether the needle gauge affect the diagnosis of the disease. Results: A total of 270 kidney biopsies were performed. Among them :72 were with 18G needles, and 198 were with16G needles. There was no difference in the number of glomeruli count under light microscope using 18G relative to 16G needles（24±11vs25±11，p=0.265）, whereas more glomeruli count were found for the 16G group using immunofluorescence microscopy(3±2 vs 5±3， p＜0.05).There was no significant difference in the adequate sample rates between 18G group and 16G group (90.28%vs93.94%, p=0.298). Minor complications including the incidence of lumbar or abdominal pain (4.17% vs 7.07%, p = 0.57), gross hematuria (4.17% vs 3.54%, p = 0.729), and perinephric hematoma without symptoms (4.17% vs1.52%, p = 0.195) were not significantly different for 18G vs 16G group. In 16G group, there was 2 cases of serious complications occurred, including severe gross hematuria requiring blood transfusion, and retroperitoneal hematoma requiring surgery. No serious complications were observed in the 18G group, even although there was no significant difference in serious complications rates between the 18G and 16G group (0% vs 1.02%，p = 1). Conclusion: There was no significant difference in the number of glomeruli, adequate sample rates, and complication rates of using the 18G and 16G needles to perform renal biopsy, and the 18G needle with smaller diameter did not affect the pathological diagnosis and classification of IgA nephropathy and lupus nephritis.

Abstract Background: Percutaneous renal biopsy (PRB) is the primary biopsy technique and it was used by 16G needles or 18G needles in China, but there is controversy about the effect and safety of the two different diameters. The study aims to compare the adequacy, complication rate and pathological classification when using 18G vs. 16G needles to perform renal biopsy with ultrasound-guidedance on native kidneys in Chinese individuals.Methods: We retrospectively analyzed the number of glomeruli, adequate sample rates, complication rates and pathological classification in 270 patients with the use of 18G or 16G needles from January 2011 to May 2017 and verified whether the needle gauge affected the disease diagnosis.Results: A total of 270 kidney biopsies were performed.

Background: Percutaneous renal biopsy is performed for diagnosis and prediction of prognosis of renal diseases. Adequacy of tissue and clinically significant bleeding are the main issues of the procedure. We aimed to compare these issues in renal biopsy by blind and real time ultrasound guided technique.Methods: It was a cross sectional, randomized study conducted between June 2016 to December 2016. In blind technique, marking for biopsy was done by ultrasound. Two attempts were performed for all and more if tissue was inadequate. Patients kept in bed rest for 24 hours, observed for post procedure hematuria and ultrasound done at 6 hours and 24 hours to diagnose perinephric hematoma.Results: Total 75 biopsies (blind = 37 and Ultrasound -guided = 38) were evaluated. Blind and Ultrasound-guided technique had significant difference of number of attempt (mean±SD) 2.4±0.6 and 2.1±0.3 (p<0.01) respectively with no difference of number of glomeruli in light microscopy. Bleeding complications were macroscopic hematuria (11(30%)vs15(40%)) and perinephric hematoma ( 5(13.5%)vs3(7.9%)) in blind and Ultrasound-guided technique respectively with no significant difference. Those patients who developed perinephric hematoma was observed in all at 6 hours.Conclusions: Ultrasound-guided technique of percutaneous renal biopsy is superior with fewer attempts and equivalent in adequacy of tissue and bleeding complication than blind technique.

Objective We assessed the use of ultrasound guided foam sclerotherapy (UGFS) to treat bilateral varicose veins either as synchronous or interval procedures. We specifically assessed total foam volume usage and its influence on early outcome and complications. Methods We reviewed our prospectively compiled computerised database of patients with bilateral varicose veins who have undergone UGFS. Duplex findings, foam volumes used and clinical outcome were assessed. Results One hundred and twelve patients had undergone UGFS for bilateral varicose veins. Sixty-one had bilateral UGFS (122 legs) and 51 had interval UGFS (102 legs). Seventy-eight percent bilateral and 60% interval procedures were for single trunk disease. Median foam volumes per treatment episode were: 17.5 mls bilateral, and 10 mls interval FS. At two weeks 81% of legs had complete occlusion after bilateral UGFS compared to 70% after interval UGFS. One patient in the bilateral UGFS developed transient visual disturbance. There was no systemic complications in the interval UGFS. Conclusions Bilateral foam sclerotherapy treatment did not adversly affect vein occlusion rates and there was no significant difference in complication rates between the two groups. Bilateral UGFS can be safely performed in selected patient presenting with bilateral varicose veins.

Abstract Objective: To evaluate the success and complication rates of ultrasound-guided renal biopsy at a tertiary care hospital. Materials and Methods: This was a retrospective analysis of 97 ultrasound-guided renal biopsies, all performed by the same radiologist, between 1 March, 2017 and 31 October, 2019. Results: Of the 97 biopsies evaluated, 87 had a definitive pathological diagnosis. In five cases (5.4%), the biopsy results were inconclusive and a second procedure was required. In seven procedures (7.6%), there were complications, all of which were properly resolved. Conclusion: Ultrasound-guided renal biopsy has proven to be a safe, effective method for the diagnosis of nephropathies, with high success rates.

Ultrasound-guided percutaneous renal biopsy has been a basic tool for the diagnosis of kidney disease, but minor and major complications cannot be completely avoided. Major complications including gross hematuria, renal hematoma and arteriovenous fistula, and usually develop within 24 hours after renal biopsy. We present an educational case of female having major bleeding complications after renal biopsy with unusual clinical courses. The patient developed hypovolemic shock at 48 hours after renal biopsy along with perirenal hematoma and hemothorax.   The case highlight the need to remain the major complications in mind for physicians. Key words: Hemothorax, renal biopsy.

Introduction: Ultrasound-guided percutaneous kidney allograft biopsy is the gold-standard for pathology work-up. Recent studies postulate better safety and efficacy for tangential approaches, however, there is no recommendation regarding biopsy needle path. In this context, we previously described the unified tangential extraperitoneal retrorenal (TER) approach for standard allograft biopsy.Methods: A single-center retrospective observational study evaluated safety and efficacy of the TER biopsy approach among 250 patients that underwent 330 ultrasound-guided kidney transplant biopsies between January 2011 and May 2020.Results: The overall major complication rate was 0.56% per biopsy attempt (1.21% per biopsy) including blood transfusion, arterial embolization and bladder catheterization for gross hematuria in 0.28, 0.14 and 0.14% of biopsy attempts, respectively (0.61, 0.30 and 0.30% of biopsies, respectively). Minor complications included subcapsular and/or perinephric hematoma, superficial bleeding, arteriovenous fistula and gross hematuria in 12.6, 3.0, 2.5 and 1.4% of biopsy attempts, respectively (27.0, 6.4, 5.5 and 3.0% of biopsies, respectively). Sample adequacy rate was 86.7%, ranging from 82.2 to 94.1% if one or ≥two cores were analyzed, respectively. Residents and consultants yielded similar complication and adequacy rates.Conclusion: According to current literature, ultrasound-guided TER kidney transplant biopsy is a safe and efficient approach eligible for nephrology training.
