Insights
Pyeloplasty is effective for pediatric patients with poorly functioning kidneys, showing good intermediate-term success rates. This procedure improves drainage and maintains renal function in most cases.
Area of Science:
- Pediatric Urology
- Nephrology
- Surgical Outcomes
Background:
- Pyeloplasty is a common surgical procedure for ureteropelvic junction obstruction.
- Assessing the efficacy in kidneys with pre-existing poor function is crucial for pediatric patients.
Purpose of the Study:
- To evaluate the efficacy and long-term outcomes of pyeloplasty in children with poorly functioning kidneys.
- To determine if pyeloplasty can improve renal function and drainage in this specific pediatric cohort.
Main Methods:
- Retrospective analysis of 39 pediatric patients who underwent pyeloplasty between 2000-2008.
- Success defined by symptom improvement or enhanced drainage on Tc-99m DTPA renography.
- Both laparoscopic and open dismembered pyeloplasty techniques were utilized.
Main Results:
- Overall success rate was 90% at a mean follow-up of 41.6 months.
- 31 out of 35 patients showed improved drainage and stable renal function post-surgery.
- 4 patients had obstructed patterns, with 2 requiring redo pyeloplasty.
Conclusions:
- Pyeloplasty demonstrates good intermediate-term results in pediatric patients with poorly functioning kidneys.
- The procedure is a viable option for improving renal function and drainage in this population.
Objective:
To determine the efficacy and long-term outcome of pyeloplasty in poorly functioning kidneys in the pediatric age group.
Method:
Retrospective data analysis was performed on patients who underwent pyeloplasty in 2000-2008. The parameter analyzed was postoperative outcome. Success was defined on the basis of either improvement in symptoms or better drainage on postoperative Tc-99m DTPA renography done after 3 months and yearly thereafter.
Results:
A total of 39 patients with a mean age of 8.6 years (4 months to 13 years), and male to female ratio of 3:1, with poor function on isotope renogram (<30%) were included in the study. Left to right side ratio was 1.3:1. Dismembered pyeloplasty was done in all patients. Laparoscopic pyeloplasty was done in 27 (66.7%) and open in 12 (33.3%) patients. Follow-up renograms were available for 35 patients: 31 showed improvement in drainage and no further deterioration in renal function and 4 showed an obstructed pattern; of these, two patients had significant deterioration in split function and the other two underwent redo pyeloplasty by open technique. At a mean follow up of 41.6 months (8-75), overall success rate was 90%.
Conclusion:
Pyeloplasty gives good intermediate-term results in poorly functioning kidneys in the pediatric age group.
