Laparoscopic pyeloplasty in pediatric patients: the SGPGI experience.
OBJECTIVE
To determine the safety, efficacy and long-term outcome of laparoscopic pyeloplasty in pediatric patients.


METHODS
A prospective analysis of data of pediatric patients under the age of 15 years, who had undergone laparoscopic pyeloplasty from January 2000 to June 2008 was done. The various parameters analyzed were; operative time, blood loss, need for analgesics, intra/postoperative complications, hospital stay and postoperative outcome. Success was defined on the basis of either improvement in the symptoms/or better drainage on postoperative isotope renography.


RESULTS
A total of 82 patients with a mean age of 7.12 years (four months to 15 years) and male to female ratio of 4.3:1 were included in the study. Dismembered pyeloplasty was done in 70 patients and Foley Y-V plasty in 12 patients via transperitoneal approach using three ports in 79 or four ports in three children. Mean operative time was 151 minutes (78-369); mean blood loss was 88.01 ml (50-250) with a mean hospital stay of 5.05 days (2-11). Conversion to open surgery was required in four (4.87%) patients. Follow-up renograms were available in 74 patients who showed improvement in drainage in 69 patients and obstructed pattern in five; of these two patients had significant deterioration in split function. Two patients among the obstructed group underwent redo pyeloplasty by open technique while the rest three elected for conservative approach. At a mean follow-up of 41.58 months (8-75) the overall success rate was 91.89%.


CONCLUSIONS
Laparoscopic pyeloplasty is effective and safe in children with minimal morbidity and gives excellent long-term results.
