Aim: To study the clinical effects of a disposable circumcision device in treatment of male patients of different ages
with either phimosis or excess foreskin. Methods: One thousand two hundred patients between the age of 5 and 95
years underwent circumcision using this procedure in the 2-year period between October 2005 and September 2007.
Of these cases, 904 had excess foreskin and 296 were cases of phimosis. Results: In 96.33% of the cases the
incision healed, leaving a minimal amount of the inner foreskin with no scarring and producing good cosmetic results.
There were no incidents of device dislocation or damage to the frenulum. The average operative time was 2.5 min for
excess foreskin, and 3.5 min for phimosis. During the 7 days of wearing the device, mild to moderate edema
occurred in 10.08 % of cases with excess foreskin and in 2.58 % of those with phimosis. Edema in the frenulum was
seen in 1.67% of patients, and only 0.67% had an infection of the incision. A total of 86.25% of patients reported pain
due to penile erection. After removal of the device, 0.58% of the cases had minimal bleeding around the incision, and
2.42% had wound dehiscence. Conclusion: The new device can be applied to an overwhelming majority of patients
with phimosis and excess foreskin. This technique is relatively simple to perform, and patients who underwent this
surgery had very few complications. Antibiotics were not required and patients reported less pain than those who
were circumcised using conventional methods. Circumcision with this device requires minimal tissue manipulation,
and is quicker and safer than circumcision using conventional techniques. (Asian J Andro 2008 May; 10: 447–454)

Male circumcision has been practiced on a large scale
for more than 5 000 years  as a way to remove the
redundant foreskin in order to expose the glans. The
A new device for minimally invasive circumcision
device distinguishes itself because it is quick, relatively
simple and safe. Fewer complications and less pain were
observed than in conventional circumcision. Patients did
not experience discomfort with the device, which is light-
weight and smooth. The foreskin was folded back, so
the layers were further from the external urethral meatus,
thus reducing exposure to bacterial infection. The linear
and even cut produced good cosmetic results as well as
meeting requirements for circumcision with minimal tis-
sue manipulation. Additional research is needed to: 1)
better evaluate pain severity associated with nocturnal
erections without the use of an anti-androgen, or with
the use of other anti-androgens, as the use of diethylstil-
besterol might not be acceptable in other settings; and 2)
evaluate use of the device in African countries with high
HIV prevalence. This device deserves wide clinical ap-
plication and evaluation in other settings.
