Appendicular Mucosal Tube Implant with Dartos Wrap Operation for Hypospadias

摘要

Aims and Objective: To develop a better operation for hypospadias patients with poor and bad quality urethral plate and damaged urethral plate as in hypospadias cripples. Materials and Methods: I operated 21 cases of hypospadias with Appendicular mucosal tube implant with Dartos wrap operation from 17/04/2017 to 03/03/2019, in Jawale Institute of pediatric Surgery, and that group was labeled as group A. 27 cases of hypospadias were operated in same time span with conventional techniques such as extended Snodgrass operation and Byar’s two-stage operation (group B), kept as control. 7 patients (33.33%) were cases of hypospadias cripples with multiple surgeries done in the past. 4 patients (9.52%) patients had congenital short urethra. Remaining 10 patients (50%) were fresh cases with no operation done in past but with bad and fibrotic urethral plate. The longest follow up was 3 years and the shortest of 1 year. Technique of Operation: Appendicectomy performed by open technique and the serosa of Appendix cut longitudinally and stripped off the mucosal tube. The proximal hypospadias opening sutured with the appendicular mucosal tube with 6 sutures of 5-0 Vicryl. Dartos fascia is raised from the scrotum wrapped over the tube and 8 - 10 interrupted stitches taken with 5-0 Vicryl. Glanuloplasty performed over it. Suprapubic diversion did and kept for 3 weeks postoperatively. Results: In group A, 3 patients developed fistula and only 1 (4.76%) required repair at the end of 6 weeks. 2 (9.52%) patients developed grade 3 infection and settled with conservative treatment. UFR was normal at the end of 12 weeks (12.85 Ml/sec. In group B, 11 patients developed fistula and 9 (33.33%) required repaired. 9 (33.33%) patients developed strictures and all of them required multiple urethral dilatation under GA. 7 (25.92%) patients developed meatal stenosis.UFR was badly reduced with average of 5.78 ML/Sec. Conclusion: The operation proves to be a much better option compared to the conventional for group A patients. We need a series with longer follow up and larger number of patients.
