Purpose: We investigate the feasibility and the result of mini-laparoscopic pyeloplasty in our hospital since 2005.
Materials and Methods: A total 7 patients aged from 43 days to 17 years old were enrolled in our retrospective review. The persisting symptoms (pain, stone, infection) and obvious deteriorated renal function were the indication for surgical intervention. The etiology, surgical finding, surgical method, operation time, number and size of troca, complication, admission days were all enrolled in our retrospective study.
Results: The average age of patients was 6.0 ± 5.3 year-old with average following up period 51.9 ± 35.6 years. The hospital days were 6.1 ± 1.8 days. The average operation time was 292.9 ± 56.3 minutes with minimal blood loss (all < 50 ml). There was only one complication recorded (Post operative urosepsis, with pre-operation finding of pyuria). The complication rate was 14.3% (1 in 7 patients). The post operation following up revealed no hydronephrosis nor obstructive finding in the DTPA scan.
Conclusion: The Mini-laparoscopic surgery brings excellent surgical result and is not inferior to the golden standard open surgery in our hospital experience in cosmetic and surgical result.
