Summary
Percutaneous endopyelotomy successfully treated 80% of ureteropelvic junction strictures. This minimally invasive approach offered a high success rate for both acquired and congenital cases, with complications managed effectively.
Area of Science:
- Urology
- Minimally Invasive Surgery
Background:
- Ureteropelvic junction (UPJ) strictures can be congenital or acquired.
- Traditional open surgery for UPJ strictures carries significant morbidity.
Purpose of the Study:
- To evaluate the efficacy and safety of percutaneous endopyelotomy for UPJ strictures.
- To assess the success rate of endourological techniques in treating UPJ obstruction.
Main Methods:
- A retrospective review of 35 percutaneous endopyelotomy procedures performed between January 1988 and December 1993.
- Posterolateral incision of the UPJ using an electric device in 34 cases.
- Mean follow-up of 45.6 months.
Main Results:
- A total of 125 patients with UPJ strictures (100 acquired, 25 congenital) were included.
- The overall success rate using endourological techniques was 80%.
- Six failures (17.1%) were managed with secondary procedures, including the Anderson-Hynes technique and nephrectomy.
Conclusions:
- Percutaneous endopyelotomy is an effective minimally invasive treatment for UPJ strictures.
- The procedure demonstrates a high success rate with manageable complications.
- Endourological management offers a viable alternative to open surgery for UPJ obstruction.
