Surgical correction and rehabilitation for children with "Prune-belly" syndrome
Insights
A novel treatment protocol for congenital absence of abdominal musculature and urinary tract deformities has significantly improved patient outcomes. This approach has led to improved survival and function in children with these complex congenital anomalies.
Area of Science:
- Pediatric Surgery
- Urology
- Developmental Biology
Background:
- Congenital absence of abdominal musculature, often termed prune belly syndrome, is associated with significant urinary collecting system deformities.
- Historically, patients faced poor prognoses with high mortality rates.
Purpose of the Study:
- To evaluate the long-term outcomes of a comprehensive treatment protocol for infants with abdominal muscle agenesis and urinary tract anomalies.
- To assess the efficacy of surgical reconstruction and functional recovery in affected children.
Main Methods:
- A protocol involving immediate bilateral tubeless pyelostomy, serial renal evaluations, and reconstructive laparotomy at one year of age.
- Surgical steps included orchiopexy, urinary collecting system reconstruction, and abdominal wall reconstruction.
- Post-operative monitoring included serial electromyography and renal function studies.
Main Results:
- Nine patients followed from age 3 to 12 years demonstrated positive outcomes, with all surviving and growing well.
- Four patients experienced chronic urinary infections, with three requiring further urinary system surgery.
- Three patients needed additional abdominal wall surgery but regained sufficient function to avoid external support devices.
Conclusions:
- The devised treatment protocol offers a highly encouraging outlook for patients with this complex constellation of congenital anomalies.
- Surgical reconstruction of the abdominal wall and urinary system can lead to significant functional improvements.
- Further research into the etiology of these conditions is warranted.
Abstract:
Until the recent past, patients born with congenital absence of the abdominal musculature, and associated deformity of the urinary collecting system, have often had an unhappy life and an early death. Twelve years ago, a treatment protocol was devised in our institution which included the following major steps: 1) bilateral tubeless pyelostomy immediately after birth; 2) serial evaluation of renal status during the first year of life; 3) laparotomy at one year of age with orchiopexy, reconstruction of the urinary collecting system and reconstruction of the abdominal wall; 4) serial electromyographic evaluation of the growth and development of the lateral abdominal musculature; 5) serial studies of renal function; 6) secondary revision of the abdominal wall and of the urinary drainage system as needed. Nine patients so treated have been followed from the third through the twelfth years of life. All are alive and growing well. Four patients had chronic urinary infection treated with long-term antibiotics; three of these have required a second surgical correction of some aspect of the urinary drainage system. Three patients have required additional surgery on the abdominal wall, but have recaptured enough function so that corsets and other devices have not been necessary. Electromyographic studies show good growth and development of some aspects of the lateral abdominal musculature which has been used in the repair. The outcome in these patients is highly encouraging for this constellation of anomalies. The cause remains controversial.
