Application of modified small bladder patch-to-bladder double-layer sutures to improve renal transplantation in mice
Bibliographic record
Abstract
BACKGROUND: This study aimed to introduce an improved surgical procedure to reduce the incidence of urinary tract complications after renal transplantation in mice using a modified bladder patch-to-bladder anastomosis technique. METHODS: Renal isotransplantation was performed in 28 male C57BL/6 mice. The urinary tract was reconstructed with a ureteral anastomosis between the donor's small bladder patch and the recipient's bladder. The bladder patch was secured through a cystotomy in the recipient's bladder mucosa and seromuscular layers, which were sutured in a double-layer manner. The food intake and survival of mice were recorded for 100 days in addition to monitoring appearance, weight, and symptoms of pain. On post-transplantation day 7, the native kidney in the recipients was removed and the transplanted kidney assessed visually. Urine leakage from the transplanted graft was monitored by assessing the degree of ascites. RESULTS: The success rate of renal transplantation was 82 % (23 of 28 cases). Arterial thrombosis at the site of anastomosis occurred in 3 cases (11 %) and hemorrhagic shock in 2 cases (7 %). The mean ± SD time of the operation in recipients was 81 ± 5 min. No complications were noted in the successfully transplanted animals. CONCLUSIONS: The modified procedure of a small bladder patch-to-bladder with double-layer suturing minimizes complications after renal transplantation in mice while requiring the same operating time as other approaches such as ureter to bladder anastomosis, which are associated with more complications.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
