[Endoscopic treatment of ureterocele in children: is a long term effective technique?].

INTRODUCTION: The endoscopic treatment of the ureterocele is a less invasive procedure. Currently, there are only a few published articles regarding the long-term outcomes of this treatment. MATERIAL AND METHODS: We have introduced this technique in our practice since 1995, and have been tracking 15 pediatric patients for long-term evaluation. RESULTS: The average operative age for endoscopic treatment is 19.40 months (1 week-8 years). In 53% of the cases, the diagnosis was made during prenatal screening. In 27% of the cases, the ureterocele was bilateral, and 47% of the patients have a double system. The indication for endoscopic treatment is 66% ureteric obstruction and 34% vesicoureteric reflux. We perform "uncapping" and incision in the two first cases and puncture in the subsequent procedure. The patients were followed for 4 years (7 months-7 years). During this time, two ureteroceles needed a second perforation, out of the seven that continued having reflux, two were treated with quimioprofilaxis and two were treated endoscopically for anti-reflux. Two patients continued to have reflux, and two were diagnosed with renal atrophy and hemiatrophy. DISCUSSION: The endoscopic treatment avoided an open surgical procedure in almost all cases. The need for anti-reflux puncture occurred in 33% of the cases.

[Cystic angiomatosis].

A case of cystic angiomatosis is presented in a patient whose clinical sign were the presence of an inguinoescrotal mass due to a retroperitoneal lymphangioma, visceral splenic lesions and diffuse skeletal lesions. This rare entity is discussed and a brief review of the literature is made.

[Our experience with aspiration of ectopic ureteroceles].

Since 1986 we have performed suction of the ectopic ureteroceles in seven cases. In four of these cases the obstruction caused by the ureteroceles affected the upper hemi-kidney. In the remaining three cases both hemi-kidneys of the same side were affected. One child suffered failure of both hemi-kidneys. All the ureteroceles corresponded to the upper hemi-kidney and were associated with ipsilateral duplicity. In four of the cases the treatment applied was the heminephrectomy of the upper hemi-kidney and the suction of the ureterocele. In one case, we did a nephrectomy and suction of the ureterocele. In the remaining two cases the suction of the ureterocele was done, as well as the ureteropyelostomy, since it was necessary to use the upper hemi-kidney in the renal TC99m dimercaptosuccinic acid scan-DMSA. In five of the children there was a collapse of the ureterocele giving good results in both kidneys. In two of the children there was no collapse, which provoked the need for removal of the ureterocele. In one of these two cases, the renal dilatation persisted later. In the last case it was necessary to perform nephrectomy due to the absence of recuperation of the renal function. Three of the children had associated reflux which disappeared in one of them, after the suction of the ureterocele. Vesical surgery might be avoided by means of the ureterocele's suction technique in 60 per 100 of the cases. However, it is essential to pursue the child's progress once every six months, in order to detect possible failures of ureterocele collapse.
