Vacuum therapy prevents corporeal veno-occlusive dysfunction and penile shrinkage in a cavernosal nerve injured rat model.

Erectile dysfunction and penile shrinkage are the common complications after radical prostatectomy. Penile rehabilitation is widely applied after the surgery. Vacuum therapy is one of the three penile rehabilitation methods used in the clinical setting, but its mechanism is not well known.

Vacuum therapy in penile rehabilitation after radical prostatectomy: review of hemodynamic and antihypoxic evidence.

Generally, hypoxia is a normal physiological condition in the flaccid penis, which is interrupted by regular nocturnal erections in men with normal erectile function. [1] Lack of spontaneous and nocturnal erections after radical prostatectomy due to neuropraxia results in persistent hypoxia of cavernosal tissue, which leads to apoptosis and degeneration of cavernosal smooth muscle fibers. Therefore, overcoming hypoxia is believed to play a crucial role during neuropraxia.

[No-flip method versus external method for Shang Ring circumcision: a meta-analysis].

Objective: To compare the effect and safety of the no-flip method versus the external method in Shang Ring circumcision.

Methods: We searched relevant randomized controlled trials published in China and abroad comparing the no-flip method and external method of Shang Ring circumcision. Based on the Cochrane Handbook for systematic review, two reviewers independently eval- uated the quality of the included studies and abstracted relevant data, followed by a meta-analysis using the statistical software Review Manager 5.

[Strategies for the treatment and prevention of priapism in children].

Priapism is defined as abnormal persisting penile erection beyond or unrelated to sexual stimulation. It is rare in children and the appropriate management consensus is lacking. We have reviewed the literature on the treatment and prevention of priapism in children in the last 5 years.
