Insights
Early complications after pediatric pyeloplasty predict recurrence. Transanastomotic diversion lowers complication rates, while preoperative diversion increases both complications and recurrence risk in children.
Area of Science:
- Pediatric Urology
- Surgical Outcomes
- Renal Function Preservation
Background:
- Pyeloplasty failure in children presents significant management challenges.
- Early detection and intervention are crucial for preserving renal function.
Purpose of the Study:
- To identify predictors of recurrence and complications following primary pediatric pyeloplasty.
- To evaluate the impact of different diversion techniques on outcomes.
Main Methods:
- Retrospective analysis of 490 renal units undergoing primary dismembered pyeloplasty (June 2001-October 2016).
- Evaluation of demographic features, operative data, clinical findings, complications, and recurrence rates.
- Statistical analysis to determine significant predictors of recurrence and complications.
Main Results:
- Recurrence and complication rates were 6.7% and 11.4%, respectively.
- Early postoperative complications (7.8% UTI, 1.8% diversion-related, 1.4% urinoma) and preoperative diversion were significant predictors of recurrence.
- Transanastomotic diversion and absence of preoperative diversion were associated with lower complication rates.
Conclusions:
- Early postoperative complications are a key predictor of recurrence after pediatric pyeloplasty.
- Transanastomotic diversion is associated with reduced complication rates.
- Preoperative diversion increases both complication and recurrence rates.
Objective:
To assess the predictors of recurrence and complications, we retrospectively analyzed our experience in primary pediatric pyeloplasty. Management of pyeloplasty failure is challenging both for patients and for surgeons, especially in pediatric cases. Early detection of recurrence and early manipulation may help preserving renal function.
Methods:
We analyzed 490 renal units who underwent primary dismembered pyeloplasty with eligible data between June 2001 and October 2016 retrospectively. Patient's demographic features, operative data, clinical findings, complications, and recurrence rates were evaluated.
Results:
Mean age at operation and the mean follow-up time after pyeloplasty was 33.9 (±43.5) and 47.6 (±37.7) months. Our recurrence and complication rates were 6.7% and 11.4%, respectively. Urinary tract infection (7.8%), diversion-related complications (1.8%), and urinoma (1.4%) were the most common complications. Presence of preoperative diversion (P = .020) and presence of early complications (P < .001) after pyeloplasty were significantly related to recurrence. Complication rates were found less in children with transanastomotic diversions (P = .002) and children without preoperative diversion (P = .005). The analysis of patients in chronological order revealed an increase in prenatal diagnosis in the recent years (P < .001). Recurrence and complications were not related to age, gender, side, preoperative radionuclide renal scan results, hydronephrosis grade, surgery type, and surgical findings.
Conclusion:
Early postoperative complication is a predictor of recurrence after pediatric pyeloplasty. Transanastomotic diversion reduces the complication rates. Presence of a preoperative diversion increases both complication rates and recurrence rates after pyeloplasty.
