  • ADVANCE IN URETHRAL RECONSTRUCTION WITH TISSUE ENGINEERING TECHNIQUES

    Objective To sum up the research advances in urethra reconstruction with tissue engineering techniques. Methods The recent original articles about urethra reconstruction with engineering techniques were extensively reviewed. Results At present, human urothelium and smooth muscle cells have been successfully harvested,cultivated, and expanded in vitro in sufficient quantitiesfor reconstruction. Tissue engineering for urethral reconstruction includes matrices alone, the body’s natural ability which induces new tissue growth, or the use of matrices with cells. Conclusion The tissue engineering materials for urethral reconstruction has been used successfully to repair defect of hypospadias and urethral strictures. The reconstructionof complex urethral defects need to be improved and developed.

  • TREATMENT OF MULTIPLE ARTERIES IN RENAL TRANSPLANTATION FROM LIVING RELATED DONORS

    To discuss renovascular reconstruction during l iving related donor kidney transplantation (LDKT). Methods Seventy-seven cases of LDKT from April 2006 to March 2008 were retrospectively analyzed, including 63 cases in single renal artery group and 14 cases in multi ple artery group. In multi ple artery group, there were 3 cases of three arteries and 11 cases of double arteries; 9 cases of donated left kidneys and 5 cases of donated right kidneys. Potential donors underwent fully medical evaluation before operation, including donor-reci pient human leucocyte antigen matchingand a cross match test. The donor’s operation of the incision either underneath the 12th rib approaching the dorsal lumbar was performed and the transplantation operation adopted the extraperitoneal approach in the contralateral fossa il iac. The arteries in the multiple artery group were implanted onto the external (or common) il iac artery different from the orthodox method. Results In multiple artery group, no blood transfusion during operation was performed, no compl ication occurred after operation and all donors were discharged after 7-9 days of postoperation. After a follow-up of 3 months to 1 year, all the recipients kept normal kidney function without renal tubule necrosis, renal artery embol ism, vascular stenosis, urinary fistula and ureter necrosis. The ultrasound examination showed that the transplanted kidney had good blood supply. There was no significant difference in the time of urine secretion, serum creatinine level after 1 week of operation, length of hospital ization between the multiple artery group and the single artery group (P gt; 0.05). Conclusion The accurate treatment of multiple artery anastomosis are critical for the safety of the LDKT.
