[Clinical efficacy of Yougui capsules and Wuziyanzong pills on oligoasthenospermia].

Objective: To investigate the clinical effects of the Chinese traditional medicine Yougui Capsules and Wuziyanzong Pills on sperm viability and motility in patients with oligoasthenospermia.

Methods: A total of 80 infertile men oligoasthenospermia were equally randomized into a trial and a control group, the former treated with Yougui Capsules at 1.68 g tid, while the latter with Wuziyanzong Pills at 6 g bid, both for a course of 12 weeks.

Tissue engineering penoplasty with biodegradable scaffold Maxpol-T cografted autologous fibroblasts for small penis syndrome.

In this study, we investigated the safety and efficacy of a poly acid-co-glycolide biodegradable scaffold (Maxpol-T) coated by autologous fibroblasts (AF) for penile girth enlargement in small penis syndrome (SPS). Eighty patients with SPS were enrolled in a clinical study at 2 medical centers; 69 patients completed the study protocol. Scrotal skin was harvested under local anesthesia, and AFs were cultured and seeded on a Maxpol-T scaffold; the cografted scaffold was implanted under the Buck's fascia of penile shaft via a circumcising incision.

Clinical features and treatment options for Chinese patients with severe primary erectile dysfunction.

Objectives: To investigate clinical features of Chinese patients with severe primary erectile dysfunction (S-PED) and to identify the ideal treatment options for this population.

Methods: Patients with PED were screened for enrollment in our study. Sexual history, marital status, and erectile function were evaluated by inquiry including International Index of Erectile Function-5.

High-flow priapism: superselective cavernous artery embolization with microcoils.

Objectives: To determine the effectiveness of superselective cavernous artery embolization.

Methods: Eight patients with high-flow priapism were included in this study. All were treated by superselective cavernous artery embolization with microcoils and gelatin sponges.

[The establishment of hypospadias rat model and embryoteratogenic test of Atrazine].

Objective: To establish an easily reproducible animal model of hypospadias and to test whether Atrazine can induce hypospadias in animal experiment.

Methods: From the 11th to 16th day after conception, 120 conceived SD rats were divided randomly into 6 groups: one coin oil group (1 ml/kg/d), two finasteride groups (10 mg/kg/d, 20 mg/kg/d), three Atrazine groups (25 mg/kg/d, 100 mg/kg/d, 200 mg/kg/d). When all pregnant rats had delivered, the new born rats were counted and the penis appearance, urethral orifice position and micturition were observed with magnifying lens and anatomy microscope.

[The clinical application of acellular urinary bladder submucosa to reconstructive the urethral duct of hypospadias patients].

Objective: Attended to apply the acellular urinary bladder submucosa in the operation of the urethral duct reconstruction of penile hypospadias.

Methods: In 2 cases, the urethral ducts were reconstructed by using the acellular urinary bladder submucosa as dorsal half of the urethra, while the preputial island flap as ventral side. In the other patient, the urethral plate was incised, similar to Snodgrass operation, the matrix was fixed to the corpora cavernosa beneath.

[Autologous buccal mucosal graft pre-transplantation for urethral reconstruction of complicated hypospadias].

Objective: Applicate autologous buccal mucosal graft pre-transplantation for urethral reconstruction of complicated hypospadias by staging.

Methods: From 1999 to 2003, 40 patients have been treated by method of autologous buccal mucosal graft pre-placing. There were two models: graft onlay and graft-tube for urethral reconstruction, and the 2rd operation was accomplished half year later.

[Twice delaying of the expanded flap].

Objective: To introduce a new method for enlarging the survival area of an expanded flap.

Methods: After the skin expander was inflated with enough injection, the first delaying was performed. In the operation, two incisions were made in the skin and subcutaneous tissue superficial to the expander capsule on both sides of the long axis of the expanded flap.

[Clinical analysis of 80 cases of breast reconstruction].

Objective: To summarize the reasons for the complications after breast reconstruction.

Methods: The reasons for the complications after breast reconstruction were analyzed in flap necrosis, abdominal wall laxity or hernia and seroma.

Results: The partial necrosis rate of LDF, TRAM and DIEP was 7.

[Clinical application of the fibrous capsule to prevent muscle tendon adhesion].

Objective: To observe the effect of fibrous capsule to prevent the flexor tendon adhesion.

Methods: Six bum patients with 33 digits were treated with the fibrous capsule of the expanded flaps which was used to wrap the exposed flexor tendon in zone III in order to prevent the flexor tendon adhesion.

Results: From 1999-2001 ,all of the patients were followed up to 1-3 years.

[Applications of ultrasound in the treatment of the complications of breast augmentation with polyacrylamide hydrogel injection].

Objective: To search for a simple and non-invasive method to assist the treatment of the complications of breast augmentation with polyacrylamide hydrogel injection.

Methods: High-frequency ultrasound was used to examine the breast and observe the distributions of the injected polyacrylamide hydrogel. The operation procedure was predetermined according to the ultrasound information.
