Total Replacement of the Human Ureter with Teflon Prosthesis

Fibrin Glue with Autogenic Bone Marrow Mesenchymal Stem Cells for Urethral Injury Repair in Rabbit Model

“…They help to maintain the luminal space and prevent calculus formation. [28][29][30][31] In this study, the epithelial layer was not removed during the surgery. Although the thickness of the uroepithelial layer was consistent in all the four groups (Fig.…”

Molecular, cellular and developmental biology of urothelium as a basis of bladder regeneration

“…Natural materials used for bladder repair/augmentation include fascia (Alonzo and Laughlin, 1964), skin (Draper and Stark, 1956), dura mater (Kelami, 1971), omentum (Goldstein et al, 1967), intestinal tract (Leong and Ong, 1972), peritoneum (Hutschenreiter et al, 1978), and epicardium (Kambic et al, 1992). Artificial materials used for this purpose include gelatin sponges (Tsuji et al, 1967), silicone (Bogash et al, 1960), polyvinyl (Kudish, 1957), and Teflon (Ulm, 1966). However, these attempts have generally failed due to mechanical, structural, and biocompatibility problems, which have led to a variety of clinical complications such as graft contracture secondary to poor vascularity and graft rejection (Taguchi et al, 1977; Goya, 1986; Gleeson and Griffith, 1992).…”

Midline extraperitoneal approach to upper urinary tract surgery: Anatomical basis of surgical technique

“…Although a midline extraperitoneal approach has been utilized for retroperitoneal lymph node dissection or sympathectomy, to our knowledge nephrectomy using this approach has not been previously described in the literature. In 1966 and 1969, Ulm reported a paramedian rectus‐retracting extraperitoneal approach for renal surgery, 2,3 and Tessler has adopted it for nephroureterectomy in 1975 4 . However, this approach has not become widely accepted, probably because of limited skin incision and limited exposure due to the costal margin.…”
