[Technical summary and experiences of urinary reconstruction in mouse kidney transplantation].

ABSTRACT

The present paper summarizes the methods and technical key points for urinary reconstruction in mouse kidney transplantation. Both bladder patch and ureter implantation techniques are feasible options for urinary reconstruction in mouse kidney transplantation. The dominant complication in bladder patch technique is ischemic necrosis of patch and distal ureter and is associated with donor mouse strains and surgical skills. The most common complication in ureter implantation technique is urine leakage and is related to recipient mouse gender and technical skills. The key technical points for bladder patch method are estimation of blood supply for bladder patch and properly trimming and suturing bladder walls. The key points for ureter implantation method are properly trimming and fixation of the ureter. Comparing with the bladder patch, the ureter implantation technique is faster, its complications are easier to be repaired by secondary surgery, but the risk of urine retention is higher at late time. The timeliness of surgical intervention is a key factor for successfully repairing the early urinary complications.
