Summary
The Acucise catheter demonstrated an 86.6% success rate in treating ureteropelvic junction (UPJ) obstruction. This minimally invasive procedure is effective for adults and children, though severe dilation impacts outcomes.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Endourology
Background:
- Ureteropelvic junction (UPJ) obstruction is a condition affecting the urinary tract.
- Treatment options for UPJ obstruction vary, with a need for effective minimally invasive approaches.
Purpose of the Study:
- To determine the efficiency of the Acucise catheter in treating ureteropelvic junction (UPJ) obstruction.
- To evaluate the Acucise endopyelotomy as a therapeutic option for UPJ obstruction.
Main Methods:
- A prospective study involving 30 patients with UPJ obstruction treated with the Acucise endopyelotomy catheter.
- Procedures included retrograde (27 patients) and antegrade (3 patients) access, with lateral incision of the stricture.
- Diagnosis confirmed via intravenous urography and diuretic renography; a 7F double-J catheter was placed post-procedure.
Main Results:
- The Acucise endopyelotomy achieved good results in 26 out of 30 patients (86.6%).
- Patients with mild pyelocalyceal dilation showed better outcomes compared to those with severe dilation.
Conclusions:
- Acucise endopyelotomy is a viable, minimally invasive treatment for UPJ obstruction in both adults and children (8 years and older).
- The degree of pyelocalyceal dilation is a significant factor influencing treatment success.
