ABSTRACT
BACKGROUND:
To present our early experience in the use of Cutting-Balloon for the treatment of resistant or relapsed ureteropelvic junction obstruction (UPJO) after a prior endourological retrograde high-pressure balloon dilatation (RHPBD). MATERIALS ANDMETHODS:
Patients with progressive hydronephrosis and impaired drainage of the renal pelvis on a diuretic renal scan were treated with RHPBD. In those patients with resistant UPJO (waist persistence after dilatation) or relapsed UPJO, we consider using a Cutting-Balloon as an alternative to our current protocol (second RHPBD or open surgery). A JJ stent was placed following the procedure, and removed at 4-6 weeks. Outcomes were evaluated 3 and 6 months after stent removal, and every 6 months thereafter, repeating renal ultrasonography and diuretic renal scan.RESULTS:
Between 2008 and 2010 we treated with Cutting-balloon 5 patients (4 male, 1 woman) with UPJO (left side 3 cases, right side 1 case, bilateral 1 case) with a mean age of 3 months (range, 10 days to 7 months). Four cases had resistant UPJO and 1 case relapsed UPJO. After the procedure, and during the follow-up period of 12 months (range, 9-18 months), no further treatment was necessary. Four patients had improvement of hydronephrosis, with normal relative renal function (RRF). One patient (RRF 18% before treatment) did not improve. No periprocedural complications occurred.CONCLUSIONS:
Cutting-balloon retrograde endopyelotomy seems to be a treatment with encouraging early results for resistant and relapsed UPJO, after a prior RHPBD. We believe that further clinical evaluation is needed to confirm these findings.
