Relationship between semen parameters, serum InhB, and INSL-3 levels, and the degree of varicocele.

Background: Varicocele is an abnormal expansion of the pampininias venous plexus in the scrotum, resulting in impaired sperm production and reduced sperm quality. The exact pathophysiological mechanism leading to varicocele-related infertility has not been fully elucidated. Although treatable, varicocele may lead to male infertility.

Feasibility study on epithelial cells regeneration after excising the demucosalized ileum for ureteral reconstructive surgery.

This study aimed to investigate the regeneration of epithelial cells in the long-term observation of ureter reconstruction by excising the demucosalized ileum. First, 8 Beagle 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.

Replacement of long-segment ureteral defect with tapered demucosalized ileum: medium-term outcomes of 4 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.
