10 year institutional experience of use of buccal mucosal grafts for complex urethral reconstruction for varied indications with its outcome

Background: The objective of the study was to evaluate long term efficacy and outcome of use of buccal mucosal graft (BMG) for urethral reconstruction in varied urologic conditions in children.Methods: We retrospectively reviewed the medical records of 41 patients from 2009 till 2019 in our institution in which BMG was used for urethral reconstruction. Clinical findings along with surgical techniques used were noted for these patients. Postoperative outcome and complications were evaluated.Results: Mean age was 6.8 years and mean follow up was for 4 years. Out of 41 patients, BMG for substitution urethroplasty was used in 25 cases of hypospadias, 4 cases of urethral stricture, 6 cases of 46 XY disorders of sexual disorders, 4 cases of Y-duplication of urethra, and 2 cases of redo-epispadias repair. 11 patients underwent one stage repairs with a success rate of 63% and 30 patients underwent two stage repair with a success rate of 66%. Analysis and comparison of the outcome in relation to the type of repair, meatal position and number of surgical procedures prior to BMG urethroplasty was statistically insignificant.Conclusions: Buccal mucosa is an ideal graft substitute for urethroplasty. Two stage reconstructions has a slightly higher success rate than one stage reconstruction but the choice of the technique must be based on patients characteristics and on surgeons preference.

Ten years’ experience of augmentation cystoplasty for varied indications and its outcome

Background: The aim of the study was to evaluate long term efficacy and complications of augmentation cystoplasty in patients with bladder dysfunction.  Methods: Our series comprises of 30 patients undergoing enterocystoplasty from March 2009 till December 2019. Clinical findings and investigations result along with surgical techniques used were noted for these patients. Postoperative complications along with urinary continence and renal outcome were evaluated.Results: Mean age of patients was 7 years and their mean follow up was for 4 years. Major complications occurred in 5 patients which were successfully managed and minor complication in 8 patients. Of these 16 patients were with neurogenic bladder and 14 with non-neurogenic bladder. The primary etiology of non-neurogenic bladder was extrophy epispadias complex (10 patients), posterior uretheral valves (2 patients), anterior uretheral valve (1 patient), and bilateral ectopic ureter (1 patient). The primary etiology of neurogenic bladder was meningomyocele (4 patients), anorectal malformation with vertebral anomalies (7 patients), partial sacral ageneis (4), nonneurogenic neurogenic bladder (1 patient). Relative continence was achieved in 97%. The preoperative serum creatinine and blood urea nitrogen (BUN) at the time of bladder augmentation (termed  creatinine-1 and BUN-1)and the serum  creatinine and BUN at the last follow up after bladder augmentation (termed  creatinine-2 and BUN-2)were sought and compared using chi square test showed statistically significant improvement (p<0.01).Conclusions: Augmentation cystoplasty is a necessary and safe procedure to increase the functional capacity of small contracted and poorly compliant bladder and allows patients to achieve relative continence and preserves renal function.

A single centre 10-year experience of Mitrofanoffs procedure for varied indications with its outcome

Background: To evaluate long term efficacy and complications of Mitrofanoffs procedure in patients with bladder dysfunction.Methods: Authors retrospectively reviewed the medical records of 51 patients who underwent construction of a continent catherisable channel (mitrofanoffs and monti) from 2009 till 2019 in our institution. Clinical findings and investigations result along with surgical techniques used were noted for these patients. Postoperative complications along with urinary continence and renal outcome were evaluated.Results: Mean age was 7 years and mean follow up was for 3 years. 27 patients were with neurogenic bladder and 24 with non-neurogenic bladder. The most common type of conduit was appendicovesicostomy (38) followed by illeal monti (12) and ureter (1). The most common stomal site was umbilicus (44) followed by right lower abdominal quadrant (6). Catherterizable conduit complications included stomal leakage in 3, mucosal prolapse at the stoma site in1 and an intra peritoneal leak requiring exploratory laprotomy and revision in1. Relative stomal continence was achieved in 98%. The preoperative serum creatinine & blood urea nitrogen (BUN) at the time of mitrofanoffs procedure at the last follow up after the procedure were sought and compared using Chi square test showed statistically significant improvement (p<0.01). No differences in outcome and complication rates were noted between different types of conduit, sites of implantation, or segments used for augmentation.Conclusions: Mitrofanoff is a safe and reliable procedure in children who are dependent on intermittent catherisation in developing countries. Appendicovesicostomy is our first option followed by yang -monti illeovesicostomy.' While stomal continence is excellent patient education, family motivation and cost reduction are important factors for its lasting efficiency.
