[Treatment of ureterocele by endoscopic puncture]

Ureterocele is a congenital cystic dilatation of the intravesical segment of the ureter. As a consequence, the proximal ureter and renal pelvis become dilated and that results in renal-parenchymal pathological involvement. Management of this anomaly is still controversial. Among the therapeutical options there is a place for endoscopic punction. Our experience with 11 patients undergoing this treatment modality is reported. In all these cases endoscopic punction was the initial treatment. In 7 patients this technique was all that was needed. The technique of intravesical punction is described and its results are specified.
