Megaprepuce Reconstruction: A Single Center Experience

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.

Byar's flaps in the management of congenital megaprepuce

INTRODUCTION

Early management of congenital megaprepuce (CMP) is necessary to address recurrent urinary tract infections and parental concerns. Different procedures, mostly using the inner preputial skin to cover the phallus, have been described. However, cosmetic appearance with the inner preputial covering of the penis is suboptimal. Owing to this, we conducted this study using outer preputial skin in the form of Byar's flaps to cover the penile shaft and analysed the results.

PATIENTS AND METHODS

This prospective study included 19 patients with CMP operated by a single surgeon using the Byar's flap technique. Following surgery patients were assessed on the 4^th post-operative day, at 3 months and 1-year post-operative for cosmetic and functional outcomes. Parental satisfaction about cosmetic results was evaluated using a subjective score. Data were collected and analysed.

RESULTS

Nineteen patients with CMP were studied with a mean age of 6.3 months. Nineteen patients (100%) patients presented with buried penis and preputial ballooning, malodorous infected urine in 15 (78.9%) patients, thin stream of urine in 17 (89.4%) and dysuria in 12 (63%) patients. One of the patients had associated glanular hypospadias and the other two had isolated chordee. There were no significant complications except for one patient who developed meatal stenosis which was later managed by a meatoplasty. All patients had satisfactory cosmetic appearance.

CONCLUSION

CMP is an uncommon but easily identifiable condition. Early surgical correction is recommended to prevent complications. Byar's flap technique yields very good functional and cosmetic results in the management of CMP.

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.

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.
