Malformations of the urinary tract
Insights
Surgical outcomes for pediatric urinary tract malformations were reviewed. Inadequate surgical indications, delayed diagnoses, and inappropriate procedures contributed to mortality in 10 out of 1500 cases.
Area of Science:
- Pediatric Surgery
- Urology
- Congenital Malformations
Background:
- Urinary tract malformations are a significant cause of morbidity in children.
- Surgical intervention is often necessary for correction.
- Assessing surgical outcomes is crucial for improving patient care.
Purpose of the Study:
- To analyze the mortality associated with surgical interventions for congenital urinary tract malformations.
- To identify factors contributing to adverse outcomes in pediatric surgical cases.
- To evaluate the effectiveness of different surgical approaches.
Main Methods:
- Retrospective review of 1500 pediatric surgical cases.
- Analysis of patient records, including diagnoses, procedures, and outcomes.
- Categorization of mortality causes and contributing factors.
Main Results:
- Ten (0.67%) of 1500 children died postoperatively or later.
- Causes of death included pneumonia, pyelonephritis, uraemia, urinary infection, peritonitis, and urinary ascites.
- Contributing factors identified were wrong operative indications (2), technical faults (1), delayed diagnosis (2), and wrong procedure type (5).
Conclusions:
- Mortality in pediatric urinary tract malformation surgery is low but associated with specific factors.
- Careful patient selection, timely diagnosis, and appropriate surgical technique are critical.
- Further research into optimizing surgical strategies for complex cases is warranted.
Abstract:
Between 1967 and 1977, 1500 children with malformations of the urinary tract were operated upon at the paediatric surgical department of the University of Tubingen. Ten children died in the early postoperative period or later on: Two patients died after operative correction of bladder extrophy following pneumonia and pyelonephritis and uraemia and urinary infection respectively. One child with a myelomeningocele had an ileal conduit performed and died two days after operation of peritonitis and urinary ascites. Two older children with reflux died in spite of successful ureteroneocystostomy, one following a cerebral haemorrhage and the other because of hypertension and uraemia. Five children with mechanical urinary obstruction died after discharge of uraemia and urinary infection. The following reasons for the deaths could be found: -- In two cases wrong indication for operation. -- In one case a technical fault at operation. -- In two cases the diagnosis was made too late. -- In five cases the wrong type of operation was used.
