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.

Revisiting ureteral substitution and its outcome in children: single centre 13 year experience

Background: Objective of this study is to explore various ureteric substitutes in pediatric age group and their outcomes.Methods: Retrospective analysis was done from 2003-2016, of all patients operated in this hospital that had undergone ureteral replacement. Thirteen such patients (5 from initially published paper (1) and 8 new patients) were followed up to find conduit patency, renal function and related complications with their outcomes assessed.Results: Ureteric substitution was done in 8 patients. Age of the patient ranged from 4 months to 8 years. Out of these for 2 patients monti tube was created; one with colon and other jejunum, rest of the 6 patient appendix was used. On follow up one patient had early appendico-ureteral leak requiring re-anastomosis and one patient had partial obstruction at 6 months corrected by dividing mesentry and untwisting appendix. With a mean follow up of 3.8 years all patients have preserved renal functions and drainage present. Also 5 patients of ureteral substitution performed at this institution and published prior were followed up with mean follow up of 10.4 years having no complaints with preserved function and unobstructed drainage.Conclusions: This small series supports that not only appendix and ileum but even colon as well as jejunum should be considered as Monti's tube for ureteric replacement, when confronting with short ureter in paediatric age group.

Evaluation of long term outcome of congenital diaphragmatic hernia survivors: a single centre 8 years’ experience in a developing nation with limited facilities

Background: The objective of the study was to find out incidence of long term complications in congenital diaphragmatic hernia (CDH) survivors in a developing nation with limited facilities.Methods: A retrospective study was done on patients who underwent CDH repair at our institution from 2012 to 2019. 71 patients were identified of these 55 patients operated in neonatal age were considered. After applying exclusion criteria 42 patients included in the study were then divided in 2 groups. Group 1 (26 patients): neonates requiring ventilation within 6 hrs of birth and group 2 (16 patients): not requiring ventilation or intubated after 6hrs of birth. Data from medical records were supplemented by a questionnaire regarding perceived physical function and medical follow up till date. Respiratory, central nervous, musculoskeletal and gastrointestinal systems were concentrated upon and questionnaire set. These were then compared with respect to their long term outcomes. Also, overall incidence of these in the two groups combined was noted compared with other studies.Results: On comparing these 2 groups incidence of long term complications was found more in group 1; however on statistical analysis difference was not significant. As also incidence of individual long term complications in all patients together were identical or lower than in other published series. Mortality in our study was 8 of 49 neonates which was 17% of all patients presenting with CDH or born at our centre.Conclusions: Despite the growing population of CDH survivors the morbidity is not very significant and most patients lead a normal average active life.

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.
