Fluoroscopy-use during ureterorenoscopy: are urologists concerned about radiation exposure? A nationwide survey in Belgium and the Netherlands.

Conclusion: There is a wide variety in the use and awareness of radiation during URS. To further reduce radiation and it's negative effect for patients and medical staff, awareness about radiation safety should increase among urologists. PMID: 31718463 [PubMed - as supplied by publisher]

In this study, we evaluated the nephrotoxicity of MC-LR in mice drinking water at different concentrations (1, 30, 60, 90, and 120 μg/L) for 6 months for the first time. The results showed that the kidney weights and the kidney indexes of mice were not altered in the MC-LR treated mice, compared with the control group. In addition, the renal function indicators revealed that the serum creatinine (SCr) levels were not significant changes after exposure to MC-LR. The blood urea nitrogen (BUN) levels were markedly decreased after exposure to 90 and 120μg/L MC-LR for 3 months. The BUN levels were lower than that ...

AbstractTo compare outcomes of a single middle calyx access (MCA) with a single upper or lower calyceal access in mini-PCNL. From May 2015 through August 2018, patients ’ files who underwent a single renal access mini-PCNL were retrospectively reviewed. All patients underwent fluoroscopic-guided access (16–20 F) in the prone position. They were categorized into group 1 (MCA) and group 2 (either upper or lower calyceal access). Compared preoperative items includ ed stone location, size, number and complexity (according to Guy’s score). The compared outcome parameters were complication and stone-free rates....

In this study, we observed that PRMT1 and its specific epigenetic marker, asymmetric di-methylated histone 4 arginine 3 (H4R3Me2a), were highly expressed in cultured renal interstitial fibroblasts. Treatment of PRMT1 with AMI-1, a selective inhibitor of PRMT1, or silencing PRMT1 with a small interfering RNA inhibited serum- and transforming growth factor beta1 (TGFβ1)-induced expression of α-smooth muscle actin (α-SMA) and collagen 1, two hallmarks of renal fibroblast activation, in a dose- and time-dependent manner. In a murine model of renal fibrosis induced by unilateral ureteral obstruction (UUO), PRMT...

ConclusionThe incidence of artery-to-urinary tract fistulas is growing due to the increasing use of urologic and vascular surgery, pelvic oncologic surgery, and radiation therapy. In addition to fistulas involving a degenerated artery and ureter or synthetic grafts and ureter, they can also involve an autogenous vein graft and the urinary bladder. In our patient, the fistula was a result of erosion of the bladder from a pseudoaneurysm at the proximal anastomosis of an autogenous vein iliofemoral bypass in an extra-anatomic position. Open surgery remains the best treatment option, although there is increasing evidence of su...

68Ga-PSMA PET/CT has become a well-established imaging modality to detect prostate cancer (PCa) metastases in biochemical recurrence. Despite its claimed specificity for PCa, 68Ga-PSMA uptake in tissues unrelated to PCa, particularly in the neovascular tissue of other cancers, has been reported in numerous studies. A 73-year-old man underwent 68Ga-PSMA PET/CT for biochemical recurrence of PCa 7 years after radical prostatectomy. The 68Ga-PSMA PET/CT showed 1 lesion with PSMA uptake in the distal left ureter. Histology revealed a low-grade noninvasive papillary urothelial carcinoma. By immunohistochemistry, PSMA expression ...

CONCLUSIONS: MV-containing miRNA-153-3p released by tubulointerstitial fibroblasts transmits to the proximal tubular epithelial cells via the damaged tubule basement membrane. It induces the apoptosis of proximal tubular epithelial cells by inhibiting Bcl-2 level and further aggravates RIF. PMID: 31799677 [PubMed - in process]

CONCLUSIONThis study demonstrated an optimal approach for relieving upper urinary tract obstruction and acute infection in which percutaneous nephrostomy drainage is preferred for patients with severe pyonephrosis, large stones (>10 mm) with high-grade hydronephrosis, steinstrasse, or failure in retrograde ureteric stent placement, while retrograde ureteral catheterization using cystoscopy is suitable for patients diagnosed with small stones (≤10 mm) and low-grade hydronephrosis.
