[Transurethral seminal vesiculoscopy combined with finasteride for recurrent hematospermia].

Objective: To evaluate the clinical effectiveness of transurethral seminal vesiculoscopy (TUSV) combined with finasteride in the treatment of recurrent hemospermia.

Methods: This study included 32 patients with recurrent hematospermia, with the disease course of 3 months to 4 years. After administration of finasteride at 5 mg/d for 2 weeks, the patients underwent TUSV for both exploration of the causes and treatment, followed by medication with finasteride at the same dose for another 2 weeks.

[Compound graft of porcine small intestinal submucosa with Schwann cells to reconstruct injured cavernous nerves and restore erectile function].

Objective: To investigate the restoration of rat penile erection by reconstructing injured cavernous nerves (CN) with a compound graft prepared from porcine small intestinal submucosa (SIS) and Schwann cells (SC).

Methods: SCs were cultured in vitro and a compound graft was prepared from the SCs and SIS. Thirty-three healthy SD rats were randomly divided into three groups of equal number, sham-operation, CN ablation, and SIS + SC graft.

[Restoration of erectile function by reconstructing cavernous nerves with small intestinal submucosa grafts].

Objective: To investigate the restoration of erectile function by reconstructing cavernous nerves (CN) with small intestinal submucosa (SIS) grafts.

Methods: We prepared SIS grafts, established rat models and divided the models into a CN ablation, a sham-operation and an SIS graft group. The CNs at both sides were severed with 1 cm ablated in the first group, and 0.
