“…The results show that complications such as fistulas occur more frequently after the Snodgrass technique than after TPOF. However, the Snodgrass technique results in a more normal-looking glans and a meatus that resembles a natural vertical slit-shaped meatus [23].…”

Background: This study aims to compare outcomes of treatment, in terms of early and late complications, between the Snodgrass and meatal mobilization (MEMO) techniques in children operated on because of distal hypospadias. Methods: The medical records of 127 children who underwent glandular, coronal, or subcoronal hypospadias repair between 1 January 2019 and 31 December 2023 were retrospectively reviewed. A total of 105 children met the inclusion criteria and were included in further analysis. The inclusion criteria were pediatric patients who underwent glandular, coronal, or subcoronal hypospadias repair using MEMO (n = 49) or the Snodgrass technique (n = 56) as a comparative group. The primary outcome of this study was the incidence of early and late complications with two different surgical techniques. Secondary outcomes were the duration of surgery, the length of hospital stay, the number of readmissions or unplanned returns to the operating room, and repeat surgeries between groups. Results: The median age of all patients was 17 (interquartile range, IQR 13, 29) months, with a median follow-up of 26 (IQR 17, 34) months. Regarding the type of hypospadias, the majority of patients in both groups were categorized as coronal and subroronal hypospadias. Regarding the incidence of postoperative complications, a significantly lower incidence of postoperative complications was found in the MEMO group compared to the Snodgrass group (n = 4; 8.2% vs. n = 14; 25%; p = 0.037). An urethrocutaneous fistula was the most common complication in the Snodgrass group (n = 8; 14.3%), while in the MEMO group, only one patient (2%) developed a fistula (p = 0.034). The incidence of meatal stenosis (p = 0.621) and wound infections (p > 0.999) was low in both groups. No further complications were recorded during the follow-up period. Duration of surgery (41 min (IQR 38, 47) vs. 51 min (IQR 45.5, 61); p < 0.001), duration of hospitalization (1 day (IQR 1, 2) vs. 3 days (IQR 2, 6); p < 0.001), and time to catheter removal (3 days (IQR 2.5, 5) vs. 6 days (IQR 6, 8); p < 0.001) were significantly lower in patients operated on with MEMO compared to the Snodgrass technique. Only one case of readmission due to severe wound infection which led to suturing line dehiscence was recorded in the Snodgrass group. The incidence of redo surgery was significantly lower in the MEMO group than in the Snodgrass group (n = 3; 6.1% vs. n = 11; 19.6%; p = 0.048). Conclusions: MEMO is a safe and effective technique that can be used for the treatment of distal hypospadias. It showed excellent outcomes, cosmetic results, and a low incidence of complications as well as a significantly shorter duration of surgery compared to the Snodgrass technique.

“…The vertical slit appearance of the meatus was better in the Snodgrass group (54.5%) than it was in the transverse preputial onlay flap group (24.2%, p = 0.023). The mean operation time was significantly higher in the transverse preputial onlay flap group (123.1 ± 6.8 min) than in the Snodgrass group (93.73 ± 3.9 min, p < 0.001) [ 20 ].…”

Purpose We conducted this study, comparing the outcomes among Transverse Onlay Island Flap, inlay grafted incised plate and our previous records of tubularized incised plate urethroplasty (TIPU) in patients with narrow urethral plates, aiming to determine which method of repair provides a good outcome. Methods This hybrid study included two datasets. The first from a prospective randomized study evaluating outcomes of two treatment modalities; Inlay graft and only flap for distal hypospadias with shallow urethral plate with 80 patients (40 patients in each group) included, the second based on our previous records of TIPU in 40 patients with distal primary hypospadias with narrow urethral plate. Results The success rate in inlay graft urethroplasty group (n = 40) was 87.5%; glandular dehiscence occurred in one case (2.5%), fistulas occurred in 2 cases (5%), and narrow meatus occurred in two cases (5%). Success rate in onlay flap urethroplasty group (n = 40) was 82.5%; glandular dehiscence occurred in two cases (5%), fistulas occurred in two cases (5%), and narrow meatus occurred in three cases (7.5%). TIPU group (n = 40) had success rate of 62.5%; glandular dehiscence occurred in eight cases (20%), fistulas occurred in five cases (12.5%), and narrow meatus occurred in seven cases (17.5%), with five cases exhibiting both narrow meatus with fistula. Conclusion Inlay graft and onlay flap urethroplasty for repair of distal penile hypospadias with narrow urethral plate had higher success rate and fewer complications than traditional TIPU. Moreover, operative time was shorter in TIPU.

Objective To evaluate the efficacy of different dressing methods in wound healing and the postoperative outcome in children who underwent hypospadias repair. Methods Altogether 109 children with distal hypospadias who underwent urethroplasty were recruited from our hospital between January 2021 and March 2023. All patients were randomized in two groups according to the different dressing methods: Group A receiving 3 M antimicrobial incise drape + MEBO (moisture-exposed burn ointment) and Group B receiving absorbent dressing + elastic bandage dressing. The age at surgery, operation time, bleeding during the dressing, postoperative changes in glans color, dressing fell off, comfort of children during the dressing, difficulty in dressing removal, and degree of pain during dressing removal were compared between the two groups. Results Differences in age at surgery (p = 0.337) and operation time (p = 0.055) were not significant between the two groups. The overall effectiveness of the dressing was better in Group A than that in Group B. Only five cases in Group A had blood leakage after dressing (p = 0.006), and there was no dressing dislocation (p < 0.001) or glans color abnormality (p < 0.001). Moreover, the number of complication cases was less. The overall comfort and pain degree during dressing removal in Group A was better than that in Group B (p < 0.001). Conclusion Postoperative dressing using 3 M antimicrobial incise drape + MEBO can achieve lower incidence rates of bleeding during dressing, postoperative glans darkening, and dressing falling off, a lower pain degree during dressing removal, and a better overall comfort level than those of the control group. This method is cost-effective and clinically safe, which contributes to the postoperative recovery of children with hypospadias and is thus worth promoting and applying.
