This local community survey showed that ∼40% of hypertension patients used HBPM frequently in primary care in China. However, certain patients chose the improper BP monitoring device or questionable reporting methods. Therefore, the use of arm-cuff electric devices with multiple memory storage or a home BP telemonitoring system should be promoted by health education targeted at hypertensive patients.

Purpose Repair of long-segment ureteral defect (LSUD) is challenging. Currently available procedures carry some potential complications. We modified the ileal graft by tapering the wall and stripping the mucosa to combat associated pitfalls and first reported the medium-term outcomes of 4 patients. Material and methods From September 2019 to October 2020, tapered demucosalized ileum (TDI) was used for LSUD reconstruction in 4 patients on the right (2 males and 2 females). Two patients were with panureteral avulsion and 2 with high-risk urothelial carcinoma in the distal ureter. TDI was made by tapering 1/2–2/3 of the antimesenteric ileal wall and stripping the mucosa with a blunt/blunt operating scissor. Follow-up modalities included serum creatinine, electrolytes, ultrasonography, CT urogram, renal scintigraphy, and ureteroscopy. Results Mean operation time was 443 min (range 360–550) and blood loss was negligible. The mean follow-up period was 29 months (range 23–36). Vesicoureteral reflux and related pyelonephritis occurred in 1 patient, necessitating a repair operation (Clavien-Dindo grade IIIb). No strictures, obstructions, metabolic disorders, or electrolyte imbalances were observed in the remaining patients. In carcinoma patients, ureteroscopy in month 18 post-operation revealed ileal mucosal regrowth in the form of dwarf isolated islands. All renal units maintained adequate drainage and function during the follow-up. Conclusions Ileal wall tapering and mucosa stripping confined to the muscularis mucosae level will not result in shrinkage, fibrosis, or stricture formation of the ileal ureter. The present work provides evidence for further application of TDI in the replacement of LSUD in patients.

This study aimed to investigate the regeneration of epithelial cells in the long-term observation of ureter reconstruction by excising the demucosalized ileum. First, 8Beagle dogs were anesthetized and the abdominal cavity was inspected for abnormalities via an abdominal incision. The right kidney and ureter were subsequently separated, and the ureter was severed from its connection to the renal pelvis and bladder and ligated distally. The 10-15 cm of ileum was used to reconstruct the ureter. The biopsies of the proximal, middle, and distal reconstructed ureter (neoureter) were collected at the first, third, fifth, and sixth month postoperatively. The regeneration of ileal mucosa at the first, third, fifth, and sixth month was observed by hematoxylin-eosin (HE) staining and immunofluorescence staining cytokeratin 18 (CK18). HE staining results showed irregular cytoarchitecture, severe nuclear consolidation, and inflammatory infiltration in the proximal, middle, and distal neo-ureters of dogs at the first month after ureteral reconstruction. With longer follow-up, the injuries of the proximal, middle, and distal neo-ureters were alleviated at the third, fifth, and sixth month after surgery. The expression of CK18 was higher in the middle neo-ureters than that in the proximal and distal neo-ureters at different time points after ureteral reconstruction and decreased with time. In summary, the present study demonstrated that demucosalized ileum was feasible for ureteral reconstructive surgery with satisfying prognostic effects.

At present, the main injuries are caused by iatrogenic factors, and iatrogenic ureteral injuries are the potential devastating complication of This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.
