Gain in Stretched Penile Length After Phalloplasty With & Without Penile Traction in Children.

Concealed penis is a rare clinical entity that affects young males. It leads to various concerns about cosmesis even though it does not necessarily affect functional aspects such as micturition and intercourse. However, data suggests that up to 4% of individuals may be affected by a concealed penis and this can lead to great distress to the patient especially as the child ages. There are different methods of phalloplasty that are performed, however none have explored the possible benefit of traction to the penis after phalloplasty to increase stretched penile length. We conducted a pilot study where we found a modest increase in stretched penile length following traction with phalloplasty and believe that addition of this step will help individuals with a concealed penis following phalloplasty gain a modest increase in length. The hypothesis of this study is that there will be a significant mean gain in stretched penile length with traction for 24 hours following phalloplasty for concealed penis. The research conducted will be a Randomized Control Trial with two groups where one group receives traction while one group does not.

The net gain in stretched penile length, stretched penile length pre-operatively and 2 weeks post-operatively will be analyzed using the independent study T-test with a P-value of 0.05 or less as significant between the two groups. The difference between the baseline SPL and post-operative SPL for each group will be assessed using the paired student t-test with a p-value less than 0.05 as significant. Sample Size for our study will be 70 patients (35 in each group).

Phalloplasty is a well-known procedure in children presenting with concealed penis as ordinary circumcision may lead to phimosis and adhesions formation between glans and skin in concealed penis. This procedure is not associated with any untoward results (except Suture Cut-through the glans skin which can be easily repaired) as only traction will be applied & SPL will be measured immediately per-op & two weeks post operatively.

Since there is currently no local study assessing the increase in stretched penile length following phalloplasty with traction, we have done a pilot study (Annexure B) whose results were satisfactory with penile traction as compared to without penile traction therefore, we anticipate a notable augmentation in stretched penile length both prior to and post the procedure in each patient. This observation implies that employing 24-hour penile traction may be a recommended course of action, potentially opening the door for more comprehensive investigations to furnish additional evidence regarding the procedure's advantages. It is important to acknowledge that this study will face limitations due to the restricted sample size, primarily attributable to the rare nature of the condition. Given the limited existing literature on the subject, the substantial prevalence of the condition, and the absence of a consensus regarding the optimal approach for concealed penis, this study could contribute to the existing body of knowledge by examining the efficacy of combining penile traction with phalloplasty.
