We included 18 consecutive cases of stenosis of the ureterovesical junction in 11 women and in 7 men between the ages of 26 and 60 years (41.6 ± 15.7): 5 cases of an obstructive megaureter without reflux (3 cases with ureteral lithiasis), 4 cases of stenosis of the ureteral meatus secondary to endoscopic bladder surgery, and 9 cases of an orthotopic ureterocele with lithiasis.
The treatment was effective in 4 of the 5 cases of megaureter, 9 cases of orthotopic ureterocele, and 4 cases of iatrogenic stenosis of the ureteral meatus.
Vesicoureteral reflux was present in 4 patients at 3 months, but had disappeared by 6 months.[sup.13] Isen treated 5 women who presented with an orthotopic ureterocele using an incision with scissors, which resulted in a 100% success rate and the clinical absence of vesicoureteral reflux.[sup.14] Moreover, Spatafora and colleagues performed a combined transurethral and percutaneous transvesical treatment using a Collins knife incision in 15 adult patients who presented with a ureterocele.
