Initial cystectomy ± adjuvant therapy had fewer recurrences than decompression ± secondary cystectomy.
Enucleation ± adjuvant therapy in the treatment of KOTs decreases the incidence of recurrences by 48.6% compared with using decompression ± secondary cystectomy.
The overall pooled weighted RR for enucleation ± adjuvant therapy and decompression ± secondary cystectomy were 18.2% (random: 95% CI = [14.3%, 22.8%]) and 27.1% (random: 95% CI = [18%, 38.5%]) respectively.
