A Systematic Review and Meta-analysis Revealing Realistic Outcomes following Paediatric Torsion of Testes
Journal of Pediatric Urology(2018)
Abstract
Summary Introduction Reported testicular loss rates following paediatric testicular torsion often reflect the surgical decision-making process, rather than long-term survival of the testes. Objectives We aim to perform systematic analysis and meta-analysis to investigate testicular salvage rates and to assess predictors of long-term viability. Study design Systematic review according to PRISMA guidelines was performed to investigate immediate and long-term (u003e12 months) testicular loss rates following torsion in the paediatric population. Literature search and study inclusion were performed by two investigators. A study quality score was derived and attributed to each study. Predictors of testicular loss were described. Proportions meta-analysis was performed with random effects modelling, and testing for heterogeneity. Results Twelve studies were includedm, 6 reporting early orchidectomy rates, and 6 reporting long-term outcomes. Study quality was generally low. Discussion The mean early testicular loss rate was 39%, whereas meta-analysis revealed late loss to approach 50%. Predictors of outcomes include prehospital symptom duration, location of presentation, transfer to a tertiary centre, social affluence and use of ultrasound prior to diagnosis or transfer. Conclusions This study has shown a considerable late testicular loss rate, which must be relayed to families even after testicular salvage. Delay in time to presentation is consistently found to predict poor outcomes.
