[Epididymal cysts in adolescents]. / Les kystes de l'épididyme chez l'adolescent.

Epididymal tumours are uncommon in children and adolescents and are usually benign. Epididymal cyst is exceptionally reported in the literature, although it is certainly underdiagnosed. The authors report 3 cases of epididymal cyst in 3 children, 12, 14 and 16 years of age. These children presented with an uncomfortable scrotal mass and were treated by excision of the cyst in every case. The aetiology of epididymal cysts is unclear. It is probably a congenital abnormality related to hormonal disorders during embryonic life. Physical examination is very important, but not sufficient for the diagnosis and must be completed by scrotal ultrasonography, which shows an echo-free cystic epididymal structure. Despite ultrasonography, the differential diagnosis of other scrotal cystic masses and even some solid epididymal tumours, which may present all of the sonographic characteristics of a cyst, must be considered. The treatment of symptomatic epididymal cyst in children must be surgical. For asymptomatic cysts diagnosed by sonography, clinical follow-up to document stability of the mass is justified.

Mesenteric adenitis caused by Yersinia pseudotuberculosis presenting as an abdominal mass.

Infection by Yersinia pseudotuberculosis has become of increasing pathological importance. Patients normally present with symptoms similar to those of appendicitis, due to mesenteric adenitis. We present the case of 3 patients infected by Yersinia pseudotuberculosis who in addition to fever and abdominal pain had a palpable abdominal mass, so great was the enlargement of the mesenteric nodes. In 2 patients a laparotomy was carried out, followed by biopsy of a mesenteric lymph node. The diagnosis of Yersinia infection was confirmed by bacterial culture of the biopsied material and also by serology. In the third patient, serological studies and ultrasonic imaging of the abdomen led to early diagnosis and surgery was avoided. We suggest that a diagnosis of mesenteric adenitis due to Yersinia pseudotuberculosis should now be considered in all patients presenting with an abdominal mass, and in whom there is an appropriate clinical and epidemiological history. The diagnosis should be confirmed by abdominal ultrasound (alternatively Computerised Axial Tomography or Magnetic Resonance Imaging) and serological studies. In this way, unnecessary surgery can be avoided.

Ureteroureteral anastomosis in the treatment of reflux associated with ureteral duplication.

PURPOSE: Reflux is the most common pathological condition associated with ureteral duplication. Based on 18 cases of reflux associated with ureteral duplication that were managed by ipsilateral ureteroureteral anastomosis, we analyzed this method of treatment and its advantages. MATERIALS AND METHODS: Between 1978 and 1991, 19 ipsilateral ureteroureterostomies were performed in 18 children. No complications were noted perioperatively or postoperatively. Average 38-month followup was uneventful. RESULTS: End-to-side ipsilateral ureteroureterostomy behind the bladder is simple and safe with respect to bladder integrity, and so it decreases morbidity and hospitalization. CONCLUSIONS: Indications for this operation are well-defined and they must be recognized.

Endoscopic management of ureteroceles in children.

OBJECTIVE: Treatment of ureteroceles in children varies according to the anatomicopathological form and the choice of the surgical team. This study tries to determine the exact value of the endoscopic management of ureteroceles in children. METHODS: Between 1987 and 1993, 11 ureteroceles in 10 children were treated by endoscopic incision: 7 intravesical ureteroceles (4 single system and 3 duplex system) and 4 duplex-system ectopic ureteroceles. The procedure consists of a tiny transversal incision at the lower and median aspects of the ureterocele. RESULTS: The dilation of the upper urinary tract disappeared or decreased in all cases of intravesical ureteroceles and in half the cases of ectopic ureteroceles. Endoscopic incision of the ureterocele led to a vesicoureteral reflux in the associated ureter in 6 cases: 54.5% (43% of the intravesical ureteroceles, 75% of the ectopic ureteroceles). Following endoscopic treatment, no further surgery was required in 5 of the 7 cases with intravesical ureteroceles (71.5%), while every case of ectopic ureterocele needed a further operation (lower tract surgery in 3 cases, upper tract surgery in 1 case). CONCLUSIONS: Endoscopic incision of ureteroceles is a simple and quick procedure which allows obstruction to be removed and the dilation of the upper urinary tract and its corresponding kidney function to be improved, particularly in the neonate. The endoscopic management of ureteroceles may in itself suffice, without necessity of further surgery. These favorable results can more readily be seen in cases of intravesical ureterocele than in those of ectopic ureterocele.
