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.

Abstract Introduction: Pleurodesis is a time-honored procedure for malignant effusion as one of the palliative procedures to treat recurrent effusions. Various agents have been used in the past such as tetracycline, talc, bleomycin, and povidone-iodine. This paper aims at evaluating safety and efficacy of povidone-iodine for the procedure. Materials and Methods: One hundred and four patients underwent of pleurodesis with povidone-iodine done at our center for malignant effusion between June 2008 and August 2015. The safety and efficacy of the procedure was analyzed. Results: One hundred and four patients of malignant effusion with mean age of 53 years and a mean follow-up of 7.8 months were evaluated. A total of 79% patients did not show any reaccumulation of fluid in their follow-up. There was no periprocedural mortality. Eight patients had severe pain; eleven patients had fever, while one patient had arrhythmia.Conclusion: Povidone-iodine is a simple, cheap, and effective method of pleurodesis with no major complication and a high success rate.

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.
