Two pelvises, one stone: A different approach for management of calculi in a duplex renal collecting system

We describe a patient with a duplex collecting system presenting with a renal calculus. Initial flexible ureteroscopy failed to reach the collecting system containing the stone due to inability to visualize an additional ureteric orifice. The patient then underwent percutaneous puncture of the stone containing moiety, followed by antegrade stent insertion. This allowed for guidewire-assisted passage of a ureteroscope into the duplex collecting system, where the calculi were identified and fragmented.

Conclusion: This study has a total complication rate of 16%, approximately 10% of those are severe. The most common complication to PCNL was infection (60%), followed by bleeding (5.4%), reoperation (1.6%) and pain (0.5%). The high prevalence of E. faecalis might need to be considered, however the results should be validated in a larger cohort, possibly with a higher rate of antibiotic resistance, before a change of guidelines regarding prophylactic antibiotics could be proposed.

Abstract Astragalus polysaccharide (APS) was modified using the Na2SeO3/HNO3 method to obtain selenized APS (Se-APS) with a selenium content of 1.75 mg/g. The structure and physicochemical properties of APS and Se-APS were investigated through transmission electron microscopy-energy dispersive spectroscopy mapping, fourier transform infrared spectroscopy, nuclear magnetic resonance, nano-zetasizer analysis, atomic force microscopy, and scanning electron microscopy. APS and Se-APS did not exhibit toxic effects on human kidney proximal tubular epithelial (HK-2) cells and were able to remove hydroxyl and DPPH ra...

ConclusionThe immune microenvironment is an important factor influencing the relapse of PC. The intratumoural density of CD3+, CD8+, CD45+, and CD163+ immunocytes was correlated with disease-free survival (DFS) in patients with PC. Immunotherapy based on T lymphocytes or tumour-associated macrophages may be a promising treatment strategy.
