Urethral Plate Substitution in Two-Stage Hypospadias Repair: Grafts Versus Flaps.

BACKGROUND: Choosing between flaps or grafts to substitute the urethral plate in 2-stage hypospadias repair has been a matter of debate with no consensus in the literature. Flaps have reliable blood supply that maybe theoretically less liable for strictures or contractures. Grafts are more versatile, which can be used in primary and recurrent cases when healthy local skin is deficient.In this report, our aim was to compare outcomes of grafts and flaps when used to substitute the urethral plate in two-stage repair of primary proximal hypospadias with ventral curvature. METHODS: This retrospective study included primary cases of hypospadias with significant curvature who underwent two-stage repair using either grafts or flaps to substitute the urethral plate in the first stage. Cases included in the study were divided into two groups according to the technique of substituting the urethral plate at the first stage of repair. During first part of the study period (2015 through 2018), we mostly used grafts to substitute the urethral plate (group A); later, we shifted to skin flaps (Group B) during the period 2019 through 2021. RESULTS: The study included 37 boys with primary proximal hypospadias who underwent two-stage hypospadias repair. The meatus position was penoscrotal in 18, scrotal in 16, and perineal in three. Inner preputial graft was used to substitute the urethral plate in 18 cases (group A), while dorsal skin flaps were used in 19 (group B). Out of the 37 cases, 27 were available at follow-up after second stage (group A = 14; group B = 13). Follow up period ranged between 6 and 42 months (mean 19.7; median 18.5). Overall, 14 cases required reoperations for different indications: partial disruptions of distal part of the repair in six, closure of urethro-cutaneous fistula in six, and urethral strictures in two. The rate of complications was higher in group A (10 cases: 71%) compared to group B (4 cases: 31%) (Fisher exact test, p-value = 0.057). CONCLUSION: Grafts were associated with higher complication rate than flaps when used to substitute the urethral plate in two-stage repair of proximal hypospadias with chordee. TYPE OF STUDY AND LEVEL OF EVIDENCE: This is non-randomized comparative study (level III evidence).

Spectrum and classification of megameatus anomalies.

OBJECTIVE: To define and classify megameatus anomalies, the parameters of a considerable number of cases were investigated and compared with those of normal children. METHODS: A total of 1150 normal babies were examined during routine nonmedical circumcision, and another 750 boys referred with hypospadias were examined during the previous 3 years. All patients were evaluated and assessed for the size, location, and configuration of the urinary meatus, and penile length and girth were measured. Children with normal size and location of the meatus were considered control group A, and 42 cases of different forms of megameatus were considered group B. Other penoscrotal, urinary, and general anomalies were examined and investigated accordingly. All data were analyzed by the SPSS 9.0.1 statistical package and compared by paired t tests. RESULTS: Forty-two uncircumcised patients aged from 1 month to 4 years (mean 18 months) were diagnosed with a urinary meatus that engrossed the whole ventral or dorsal aspects of the glans, exceeding half the width of the glans or penile girth with the complete vanishing of the glans closure in most cases. Megameatus is usually associated with the abnormal meatal position as hypospadiac, orthotopic, or epispadic. Additionally, megameatus may be associated with a normally intact or deficient prepuce. Consequently, we had four categories of megameatus, and the intact prepuce orthotopic megameatus subcategory has not been described before. Megameatus was also detected with deficient prepuce, and this was considered a hypospadiac variant. CONCLUSION: Megameatus is diagnosed precisely with penile biometry and is classified into 4 groups: hypospadiac, epispadic, and orthotopic or central, either with or without intact prepuce. This classification is applicable for expansion to other centers.

Pigmentary complications after non-medical male circumcision.

BACKGROUND: A wide spectrum of complications are reported after male circumcision (MC), the non-aesthetic complications are well known, but the pigmentary complications scale are not reported precisely. METHODS: This is a prospective cohort study of 550 circumcised boys; aged from 6 months to 14 years (62% aged 5 years) who were examined and appropriately investigated for the incidence of pigmentary complications after circumcision. Most diagnoses were clinically, but dermoscopy was done for 17 case and a skin biopsy for 14 cases. Patients with personal or family history of vitiligo, or congenital nevi were excluded. Available hospital records details and parents' statements were revised. The main outcome measures are the incidence of different pigmentary complications and circumcision details; data were analyzed by a non-parametric tests including the Mann-Whitney U test. RESULTS: 69 cases had 72 confirmed pigmentary complications discovered at 2-36 months after commencement of circumcision (mean 18). 48 cases had pigmentary complications directly related to MC, 11 cases were probably related and 10 unrelated to MC. The most common lesion is the circular hyperpigmented scar (29 cases); liner hyperpigmented scar in 13, spotted exogenous melanosis in 18 cases, melanocytic nevi (7), hypopigmentation diagnosed in 3 cases, but kissing nevus is the rarest finding (2). Topical corticosteroid was tried in 15 cases, surgical excision of pigmented scar were done for 19 cases, local laser used for 4 resistant cases and reassurance with follow up for the rest. CONCLUSION: Pigmentary complications after male circumcision are not rare and its management is challenging.
