Dismembered pyeloplasty in children with and without stents
Insights
Performing pyeloplasty without stents in infants is safe and cost-effective. This approach reduces hospital stays, antibiotic use, and febrile episodes compared to stented procedures.
Area of Science:
- Pediatric Surgery
- Urology
Background:
- Pyeloplasty is a common surgical procedure for ureteropelvic junction obstruction.
- The use of internal stents during pyeloplasty is a debated topic.
Purpose of the Study:
- To evaluate the benefits and safety of nonstented pyeloplasty in infants.
- To compare outcomes between stented and nonstented pyeloplasty.
Main Methods:
- A retrospective study of 48 infant pyeloplasties performed between 1987 and 1992.
- Comparison of outcomes between a group of 23 stented cases and 25 nonstented cases with external drainage.
- Exclusion of patients with poor renal function or extreme pyelocaliectasis.
Main Results:
- The nonstented group experienced fewer febrile episodes and required less antibiotic treatment.
- Hospitalization duration was significantly shorter in the nonstented group.
- Pre- and postoperative renal function remained comparable between both groups.
Conclusions:
- Nonstented pyeloplasty in infants is a safe and effective alternative to stented procedures.
- This technique offers significant cost and resource utilization benefits.
- Eliminating the need for internal stents simplifies the procedure and reduces patient morbidity.
Objectives:
To assess the benefit of performing nonstented pyeloplasty in infants.
Methods:
Forty-eight consecutive pyeloplasties were performed by two surgeons using different techniques, from 1987 to 1992. One used stents in all cases (23) and the other performed a nonstented anastomosis with external drainage (25 cases). Patients with specific indications for internal drainage, i.e. poor renal function, extreme pyelocaliectasis, were excluded from the study. Parameters of cost and complications were assessed.
Results:
The group with stents had more febrile episodes, needed more antibiotics and were hospitalized twice as long as the nonstented group. Pre- and postoperative renal function was similar in both groups.
Conclusions:
Performing pyeloplasties in children without stenting the anastomosis is safe and cost-effective.
