Unilateral Renal Tumor Cryoablation and Contralateral Radical Nephrectomy of Bilateral Renal Tumors by Transumbilical 3D Multichannel Laparoendoscopic Single-Site Surgery.

Unilateral renal tumor cryoablation and contralateral radical nephrectomy of bilateral renal tumors were performed by transumbilical three-dimensional (3D) multichannel laparoendoscopic single-site (LESS) surgery, in an attempt to verify the feasibility and safety of the procedure, sum up the operational experience, and evaluate the surgical outcome. This was a 47-year-old female patient with a body mass index of 27.34 kg/m without backache, low back pain, hematuria, urinary urgency, frequent urination, dysuria, and other symptoms.

[Small-dose vardenafil restores erectile function after penile surgery].

Objective: To investigate the impact of penile surgery on the erectile function of the patient and to evaluate the role of small-dose vardenafil in restoring the impaired penile erection.

Methods: Sixty cases of penile cavernosum surgery were equally and randomly divided into a vardenafil and a control group, the former treated 5 - 7 days after surgery with 10 mg vardenafil every other day, while the latter given vitamin E at 100 mg once a day, both for 12 weeks. The penile erectile function of the patients was evaluated with the IIEF-5 questionnaire before surgery and at 3 and 6 months after vardenafil medication.

[Repair and functional reconstruction of the penis (a report of 62 cases)].

Objective: To investigate the effects of surgery treatment on serious penile lesions and malformation.

Methods: Sixty-two patients, aged from 19 to 63 years old (mean 35 ys), were included in the study. Among them, 4 patients suffered from penis partial defection were respectively treated with restoring defective penis, penis lengthening and urethroplasty; three patients with penis completely missing were treated with penis reconstruction surgery; 22 cases with serious penile curvature were treated with the 16-dot plication technique (Lue's procedure); 15 cases with penile fracture were treated with conservative treatment for 1 case and with patch penis, corpus spongiosum, and deep penile dorsal vein ligation for 14 cases; 5 cases with post-operative complications of 3-pieces of penile prosthesis, including the prosthesis perforating to the urethra, water pump failure, broken connection tube, erection angle < 60 degrees and failure to expansion the corpus cavernosum, were treated by taking out prostheses, urethral repair cracks, replacement of the prostheses, excision of fibrosis scar and re-implantation prostheses respectively.

[Duckett's procedure of one-stage urethroplasty for hypospadias].

Objective: To study the clinical effect of Duckett's procedure of one-stage urethroplasty with the transverse preputial island flap in the treatment of hypospadias.

Methods: We retrospectively studied 20 cases of hypospadias treated by Duckett's procedure of one-stage urethroplasty with the transverse preputial island flap (Group A) from 2003 to 2007. The patients ranged in age from 2 to 22 years (mean 11.

[Successive "Z" incision and skin flaps: a better procedure for penile lengthening].

Objective: To recommend the successive "Z" incision and skin flaps as a method for repairing the wound in penile lengthening procedures.

Methods: We performed penile lengthening surgery by successive "Z" incision for 5 patients complaining of short penis, who ranged in age from 16 to 34 years (22.4 +/- 7.

Penile and scrotal Paget's disease: 130 Chinese patients with long-term follow-up.

Objectives: To report a retrospective series of 130 Chinese patients with penoscrotal extramammary Paget's diseases (EMPD), with a long-term follow-up, and thus improve the diagnosis and therapy of this disease.

Patients And Methods: The history, clinical presentation, pathology, treatment, and prognosis of 130 patients were analysed. All cases were confirmed by skin biopsy, and then the patients had local wide resection to remove the involved skin and subcutaneous tissue.
