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

Abstract

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.
