Augmentation Cystoplasty in Children: Institute of Kidney Diseases Peshawar Experience

Objective: The aim of this study is to share our single-center experience of Augmentation Cystoplasty (AC) in children regarding indications, bowel segment used, associated procedures, and its complications. Materials and Methods: We analyzed data of all pediatric patients who underwent AC at Institute of Kidney Diseases (IKD), Peshawar between July 2017 and March 2020. Results: A total of 18 pediatric patients are included in the study who underwent Bladder augmentation (BA) either isolated in 1 (5.5%), or along with other associated procedures like Mitrofanoff 17 (94.4%), Antegrade Continent Enema (ACE) 6 (33.3%), Bladder Neck Reconstruction (BNR) 5 (27.7%) and Bilateral ureteric Re-implantation (B/L UR) in 3 (16.6%). Indication for Bladder augmentation were Neurogenic bladder (NGB) 13 (72.2%), Exstrophy Epispadias Complex (EEC) 3 (16.6%) and Posterior urethral value with small functional capacity bladder 2 (11.1%). Small gut used in 15 (83.3%) and large gut in 3 (16.6%) for BA. For Mitrofanff associated with bladder augmentation, Appendix was used in 14 (82.35%) and small gut (Monti) in 3 (17.6%) cases. For ACE associated with BA, in 4 (66.6%) Appendix used as right-sided ACE and in 2 (33.3%) small gut (Monti) as left-sided ACE. No intraoperative complications noted, while early post-op complications, 2 wound infection and 1 urinary leakage from wound, were noted in 3(16.6%) cases and late post-op complications (stomal stenosis) in 4(22.2%) patients.

Bladder neck reconstruction in girls’ pelvic fracture bladder neck avulsion and urethral rupture

Background Girls’ pelvic fracture bladder neck avulsion and urethral rupture is rare however it causes great morbidity. The management is complex and not standard yet. We report our experience and a technique of bladder neck reconstruction with anterior bladder wall flap. Methods We retrospectively analysed data of 5 girls with pelvic fracture bladder neck avulsion and urethral rupture admitted to our institution from July 2017 to October 2019. They all came to our institution with a suprapubic tube. Patients’ trauma was all initially treated at other hospitals, 4 had suprapubic cystotomy and 1 had urethral realignment. One girl also had three other urethroplasties at other hospitals. We took pubectomy, posterior ureth roplasty and bladder neck reconstruction with anterior bladder wall flap in these 5 girls. Post-operative assessments included voiding cystourethrography, uroflowmetry and urethroscopy after urethral catheter removal. Verbal consent to participate was obtained from the parent or legal guardian of the children. Results Operation time ranged from 120 to 180 min. Follow-up time is 12 to 27 months. Uroflowmetry showed that maximum urine flow rate improved significantly. Cystourethrography indicated good continuity of the urethra. Two girls had urinary incontinence postoperatively but were continent 3 months later. One patient developed vesical-abdominal fistula and got repaired by surgery 6 months later. She was continent ever since. Other complications were not observed during the follow-up period. Conclusions Our method of bladder neck reconstruction using bladder flap as a patch is feasible and provides good continence, especially for those with serious bladder neck avulsion and urethral rupture caused by extensive trauma and those who had posttraumatic urethral distraction needed second repair.

Delayed primary bladder’s closure in children with exstrophy, microcystis

Introduction. The small size of the bladder plate is a poor prognostic sign for successful treatment of exstrophy. Primary closure in newborns and infants with microcystisis often accompanied by complications and relapses; there for, the approach to the treatment of this group of patients requires a more detailed analysis. The aim of the study. Identify advantages and disadvantages of delayed primary closure surgery in patients with bladder exstrophy and microcystis. Materials and methods. During the period from 1994 to 2020, 265 children with bladder exstrophy were subjected to surgery, 123 patients were newborns. There were 37 children with microcystis (bladders plate <3 cm). In 30 children, primary closure was performed at the newborn age. Seven patients with microcystis were subjected to everyday manual and mechanical stretching of the bladder and injections of botulinotoxin type A into the bladder plate (2-3 times) for 1-2 years. In 5 children the size of the bladder plate was increased from 3 cm to 6 cm, they were underwenteded delayed primary closure at the age of 1-2 years, supplemented by ureteroneoimplantation, bladder neck reconstruction, with bilateral osteotomy. Results. Complications of primary closure in patients operated on during the neonatal period (30) such as relapse of the exstrophywere observed in 10 patients (33.3%) and partial wound dehiscence in 3 children (10%). In patients with microcystis that underwent delayed primary closure after stretching the bladder, there was no relapse of exstrophy, and growth of the bladder was observed. Conclusions. In our opinion, delayed primary closure of the bladder in children with microcystis after mechanical stretching of the bladder plate in combination with injections of botulinum toxin type A into the detrusor can improve the results of correction of exstrophy.
