Surgical treatment of the massively dilated primary megaureter in children
Insights
Tailored reimplantation surgery, involving ureteric tailoring and excision of the atonic segment, is highly effective for managing massive primary megaureter in children. This approach achieved a 98% success rate, correcting previous failures.
Area of Science:
- Pediatric Urology
- Surgical Gastroenterology
Background:
- Primary megaureter is a congenital condition characterized by massive ureteric dilatation.
- A significant proportion of children with this condition experience complications such as febrile infections, sepsis, and azotemia.
- Surgical intervention is often necessary for severely affected cases.
Purpose of the Study:
- To evaluate the efficacy of a specific surgical technique for managing massive primary megaureter in children.
- To identify critical components for successful surgical outcomes in these complex cases.
Main Methods:
- Retrospective analysis of 83 children with primary megaureter from 1964 to 1975.
- Surgical treatment involved ureteric reimplantation with excision of the atonic distal segment.
- Tailored reimplantation techniques were compared with non-tailored approaches.
Main Results:
- Of 41 children requiring surgery, tailored reimplantation achieved a 98% success rate.
- Non-tailored reimplantation was uniformly unsuccessful.
- All previously failed cases were successfully treated with tailored reimplantation.
Conclusions:
- Successful surgical management of massive primary megaureter secondary to an atonic ureteric segment requires specific techniques.
- Key elements include excision of the atonic segment, tailored ureteric tailoring (transvesical or extravesical), and reimplantation.
Abstract:
From 1964 to 1975, of 83 children with primary megaureter 33 had unilateral and 8 bilateral massively dilated ureters that required surgical treatment, and of these 73% had febrile infection, 5% were septic and 10% were azotaemic. Surgical treatment consisted of ureteric reimplantation with excision of the atonic distal segment, preceded by diversion when indicated. Tailored reimplantation was successful in 98% of ureters and non-tailored reimplantation was uniformly unsuccessful. All failures were successfully corrected by tailored reimplantation. Thus the requirements for successful surgical management of massive ureteric dilatation in children secondary to an atonic ureteric segment are excision of the atonic segment, transvesical or extravesical tailoring of the ureter and reimplantation.
