Congenital megaprepuce: a new alternative technique for surgical correction

Surgical correction of congenital megaprepuce: a pilot study

OBJECTIVE

Congenital megaprepuce (CMP) is a rare penile deformity that usually requires surgical correction. This study was performed to examine the efficacy of the modified Sugita procedure for repairing CMP in pediatric patients.

METHODS

We retrospectively analyzed the clinical data of pediatric patients with CMP treated by a surgeon using the modified Sugita procedure in our hospital from January 2019 to April 2021.

RESULTS

Twenty patients were enrolled, and their median age at surgery was 70.5 months (range, 60-96 months). All surgeries were successful, and no complications occurred during the operation. The postoperative foreskin had moderate edema in five patients, and soaking in 10% hypertonic saline resulted in disappearance of the edema within 4 to 8 weeks. The follow-up duration was 6 to 20 months (median, 10 months). No other complications occurred, such as dehiscence or hematoma.

CONCLUSIONS

The modified Sugita procedure for correction of CMP produces excellent cosmesis and a low complication rate. Our study indicates that the modified Sugita procedure is a safe and feasible treatment option.

Megaprepuce: a systematic review of a rare condition with a controversial surgical management

Megaprepuce (MP) is a rare and challenging condition characterised by an excessive inner prepuce, paucity of penile skin and an extremely narrow phimotic ring. The aetiological factors leading to its development are poorly understood. A variety of surgical techniques have been described in the last 26 years mostly with small number of patients and short follow-up. It is also highly likely that some series have in the past included different variants of inconspicuous penis combining concealed penis, MP and webbed penis. This article is a systematic review of the literature on Megaprepuce; in particular the embryology, history, aetiology, and the surgical techniques available for the correction of this unique penile anomaly will be presented and discussed in this study.

Megaprepuce: A New Surgical Technique with Excellent Cosmetic and Functional Results

Background: Congenital megaprepuce (CMP) is a malformation consisting of redundant inner foreskin, normal penile shaft, and severe phimosis. The excess inner prepuce pushes the penile shaft deeper causing the appearance of a buried penis. We describe a novel surgical technique using dartos fascial flaps to reconstruct the prepuce giving excellent cosmetic and functional results. Patients and Methods: Penile reconstruction was performed by a single surgeon in 07 cases of CMP between January 2018 and December 2019. In all cases, the described surgical technique was used. Following surgery, cosmetic and functional outcomes were reviewed as well as the incidence of complications. The patients' ages ranged from 15 to 27 months (mean = 19). Mean hospital stay was 9 hours (range = 7-12). Operating time was between 50 and 85 minutes. Results: Postoperative appearance of the penis was satisfactory for all the parents in our group. Swelling of the penile shaft was seen in all of our patients but settled within one week of surgery. Scrotal hematoma was seen in only one of our patients, but that also did not need any intervention and settled spontaneously. During the follow-up period (mean = 14.5 months, range 6-24) no patient underwent revision surgery. In all our patients, the final appearance was of a circumcised penis. The final similarity to a normal circumcised penis was excellent in all of our patients. Correction of penoscrotal transposition was done in all patients achieving an elongated penile shaft and almost invisible postoperative scarring. Conclusion: Our modified surgical procedure to correct CMP is a safe and simple technique, providing good cosmetic results with the appearance of a standard circumcised penis. This also provides a good functional outcome with complication rate quite low. This technique is also easy to reproduce and teach compared with other complex procedures.

Megaprepuce: presentation of a modified surgical technique with excellent cosmetic and functional results

OBJECTIVE

Congenital megaprepuce is a malformation consisting of a great redundancy of the inner preputial skin over a penis with normal shaft and glans and is combined with a severe phimosis. Patients suffer from difficulties in voiding because the urine is trapped in the large dome-shaped megaprepuce. We describe a modification of the surgical technique of reconstructing a megaprepuce initially presented by Leao et al.

PATIENTS AND METHODS

We retrospectively reviewed 7 patients aged 6-53 months (mean age 17 months, 6 were younger than 18 months) who underwent congenital megaprepuce repair between 02/2014 and 05/2018 in our institution. All these otherwise healthy children suffering from difficulties in voiding and reporting genital ballooning during micturition and urinary retention were referred to our hospital. In all cases, parents needed to express the trapped urine. Four of these patients additionally showed a glanular hypospadias, another one a distal penile hypospadias. In addition to the repair of the megaprepuce, six patients needed correction of a penile curvature, five of whom needed correction of the chordee and one a corporoplasty (Schröder-Essed). The patient showing the distal penile hypospadias additionally underwent hypospadias repair. During the follow-up, we evaluated the cosmetic result and complications such as secondary concealed penis, difficulties in voiding, urinary retention, and urinary infections.

RESULTS

Mean follow-up was 18 months. All patients following surgery showed normal voiding without urinary retention or urinary infections and good cosmetic results resembling a circumcised penis in appearance without reconcealment. No intraoperative complications occurred. One patient had a scrotal hematoma postoperatively. Mild transient edema of the penis was seen in all patients, which disappeared spontaneously within one week after surgery.

CONCLUSION

Our surgical approach is a safe and relatively simple procedure with a low rate of complications, good cosmetic results, and functional outcome. Whether the hypospadias associated with ventral curvature was a coincidence or part of the disease pattern remains unclear but will probably be the object of further investigations.

Congenital Megaprepuce: Literature Review and Surgical Correction

Congenital megaprepuce (CMP) is a type of buried penis characterized by extensive redundancy and ballooning of the inner prepuce as a result of preputial stenosis and phimosis. The malformation typically presents with difficulty voiding, often requiring manual expression of stagnant urine. Multiple techniques have been reported for the treatment of CMP with varying levels of positive outcomes. The authors provide a review of published literature, in addition to describing the procedure and results of our surgical technique in three children aged eleven months, two years, and twelve years. The literature review was conducted using PubMed with keywords “congenital megaprepuce,” “megaprepuce,” “buried penis,” “CMP,” and “correction.” Results were then differentiated based on presence or absence of true congenital megaprepuce and the surgical correction thereof. Regarding our cases, all patients completed the procedure with excellent cosmesis and without complication. Our technique is shown to provide consistent, excellent esthetic outcome across a wide range of ages and may be replicated by others.

Megaprepuce Reconstruction: A Single Center Experience

INTRODUCTION

Surgical treatment of congenital megaprepuce is challenging and controversial. We report our 10-year experience treating patients with this deformity using a standardized procedure that has similarities to a technique reported by Smeulders et al. (1). Our postoperative complications and mid-term follow-up cosmetic appearance of the genitalia after reconstruction are reviewed.

MATERIAL AND METHODS

Fifteen patients operated on between 2005 and 2015 were evaluated. Age at surgical repair ranged from 3 to 20 months (mean 9). Treatment included unfolding the preputial sac via a ventral approach, excision of redundant inner preputial skin, and ventral skin coverage with the outer preputial layer. Twelve patients presented associated partial scrotal engulfment, which was simultaneously treated. Mean follow-up was 4.6 years (range 2-7 years).

RESULTS

Short-term complications occurred in three patients: scrotal hematoma in one patient and small skin dehiscence at the penoscrotal junction in two patients. Skin disruption healed by secondary epithelial ingrowth. All cases resulted in a satisfactory genital cosmetic outcome. There were no late complications. All patients preserved normal external genitalia appearance.

CONCLUSION

Our experience is in agreement with reports of other authors; suggesting that excision of the inner preputial layer and using the external one for penile coverage provide good and durable mid-term esthetic results in megaprepuce reconstruction.
