Insights
Glanular decompression and expansion surgery is effective for proximal hypospadias with hypoplastic glans penis, significantly reducing glanular dehiscence and improving penile size. This surgical approach enhances patient and physician satisfaction with penile appearance.
Area of Science:
- Pediatric Surgery
- Urology
- Reconstructive Surgery
Background:
- Proximal hypospadias with a hypoplastic glans penis presents reconstructive challenges.
- Current surgical techniques aim to improve both functional and aesthetic outcomes.
Purpose of the Study:
- To evaluate the clinical efficacy of glanular decompression and expansion surgery.
- To compare this technique with conventional glanuloplasty for proximal hypospadias with hypoplastic glans penis.
Main Methods:
- Retrospective analysis of pediatric patients from January 2020 to June 2023.
- Comparison between a conventional glanuloplasty group (n=26) and a glanular decompression and expansion group (n=28).
- Evaluation of surgical outcomes, complications, penile growth, and appearance satisfaction.
Main Results:
- Glanular decompression and expansion significantly reduced postoperative glanular dehiscence (P=0.047).
- The glanular width was significantly greater in the decompression and expansion group one year postoperatively (P=0.031).
- No significant differences in overall complication rates or urethral fistula incidence were observed between groups.
Conclusions:
- Glanular decompression and expansion surgery is effective in reducing glanular dehiscence in this patient population.
- The technique improves glanular size and patient/physician satisfaction with penile appearance.
- Efficacy in reducing urethral fistula and overall complications requires further investigation.
Objective:
To evaluate the clinical efficacy of glanular decompression and expansion surgery in repairing proximal hypospadias accompanied by hypoplastic glans penis.
Methods:
Clinical data from pediatric patients with proximal hypospadias and hypoplastic glans penis admitted to the pediatric surgery department of First People's Hospital, Zunyi City from January 2020 to June 2023 were retrospectively analyzed. Patients were divided into two groups according to surgical approach: a conventional glanuloplasty group (n = 26) and a glanular decompression and expansion group (n = 28). Surgical outcomes, postoperative complications, penile growth, and satisfaction with postoperative penile appearance were compared and analyzed between the groups.
Results:
No statistically significant differences existed between the two groups in preoperative baseline clinical data(P > 0.05).In the conventional glanuloplasty group, complications occurred in 10 cases (38.46%),including glanular dehiscence in 4 cases (15.38%), urethral stenosis in 2 cases (7.69%), urethral fistula in 3 cases (11.54%), and recurrent penile curvature in 1 case (3.85%). In the glanular decompression and expansion group, 6 cases (21.43%) experienced complications, comprising urethral fistula in 3 cases (10.71%), urethral stenosis in 2 cases (7.14%), urethral diverticulum in 1 case (3.57%),and no cases of glanular dehiscence. The incidence of postoperative glanular dehiscence was significantly lower in the decompression and expansion group compared with the conventional group (P = 0.047),There were no statistically significant differences in the overall complication rate, incidence of urethral fistula, or urethral diverticulum between the groups (P > 0.05).One year postoperatively, the glanular width in the decompression and expansion group was significantly greater than that in the conventional group (1.34 ± 0.13 cm vs 1.40 ± 0.08 cm; P = 0.031).
Conclusion:
Glanular decompression and expansion surgery effectively reduces the incidence of postoperative glanular dehiscence in proximal hypospadias patients with hypoplastic glans penis. Additionally, this technique enhances glanular size and improves the satisfaction of physicians and patients' families regarding penile appearance. However, its efficacy in reducing urethral fistula and overall complication rates remains limited.
