Ureterocele calculi are developed in cavities with urinary retention but far from the upper renal cavities. The structural
features of three ureterocele calcium oxalate stones were observed by scanning electron microscope coupled with X ray microanalysis.
The urinary parameters of the three patients were also determined. The stone A consisted of loose structure of large calcium
oxalate dihydrate crystals and small spheres of hydroxyapatite. The interior contains disorganized plate-like calcium oxalate
monohydrate crystals. The stone B was formed by a compact outer layer of calcium oxalate monohydrate columnar crystals. The
structure of stone interior was similar to the stone A. The stone C was formed by concentric layers composed of either calcium
oxalate monohydrate columnar crystals or hydroxyapatite. The core consisted of agglomerated calcium oxalate monohydrate crystals,
hydroxyapatite and organic matter. From the urinary biochemical data it was deduced that two ureterocele patients (who formed
A and B stones) were hypercalciuric (calcium > 300 mg/24 h), being 6.5 the urinary pH value of the patient that formed the
A stone, and 7.0 the urinary pH of the patient that formed the C stone. The rest of urinary parameters for the three patients
were normal. Thus, one of the requisite conditions for unattached stone development is the existence of a place inside the
urinary tract where the solid particles that act as calculus initiator of the stone can be retained enough time to exert this
action. 相似文献

Objective
The aim of the study was to evaluate clinical characteristics of ureteroceles particularly for diagnostic and treatment challenges.Methods
Data about patients treated for ureterocele in the two hospital clinics during 1996- 2009 are retrospectively evaluated.Findings
There were 12 girls and 7 boys. Symptomatic urinary tract infection was found in twelve cases. Ureterocele was associated with duplex systems in eleven cases. Vesicoureteral reflux was detected in 4 patients. Bladder diverticulum complicated with ureterocele in 1 patient. Ultrasonography diagnosed ureterocele in 12 patients. Renal scarring was detected in 6 patients at the side of ureterocele. Fifteen patients showed varying degrees of hydro-ureteronephrosis. Surgical therapy included upper pole nephrectomy in 3 cases. Bladder level reconstruction was performed in 11 cases. Five patients were treated only by endoscopic incision. In the follow up period 4 patients showed long term urinary tract infections whereas 3 of them were treated endoscopically. Postoperative reflux was still present in two patients who were treated by endoscopic incision.Conclusion
Ureterocele diagnosis and treatment show challenges. Urinary tract infection is important marker for urinary system evaluation. Preoperative management generally depends on a combination of diagnostic methods. Endoscopic incision needs serious follow up for postoperative problems. 相似文献65.

Obstructive ureterocele—an ongoing challenge 总被引:3,自引:0,他引:3
Ureterocele is a cystic dilatation of the intravesical ureter that is most commonly observed in females and children, and usually affects the upper moiety of a complete pyeloureteral duplication. According to their position, ureteroceles are divided into intravesical, when the ureterocele is completely contained inside the bladder, and extravesical when part of the cyst extends to the urethra or bladder neck. Most ureteroceles are diagnosed in utero or immediately after birth during an echographic screening of renal malformations. Severe, febrile urinary tract infection is the most common postnatal presentation of ureteroceles, but they may, rarely, prolapse and acutely obstruct the bladder outlet. Once an ureterocele is identified sonographically, a voiding cystourethrogram to detect vesicoureteral reflux (VUR) and a 99m-technetium dimercapto-succinic acid renal scan to evaluate the function of the different portions of the kidney are mandatory. VUR in the lower pole is observed in 50% of cases and in the contralateral kidney in 25%. Simple endoscopic puncture of the ureterocele has recently been advocated as an emergency therapy for infected or obstructing ureteroceles and as an elective therapy for intravesical ureteroceles. The rate of additional surgery after elective endoscopic puncture of an orthotopic ureterocele ranges from 7 to 23%. Treatment of ectopic ureteroceles is more challenging and both endoscopic puncture and upper pole partial nephrectomy frequently require additional surgery at the bladder level. The reoperation rate after endoscopic treatment varies from 48 to 100%. It is 15 to 20% after upper pole partial nephrectomy if VUR was absent before the operation, but is as high as 50–100% when VUR was present. Thus, endoscopic incision is appropriate as an emergency treatment or when dealing with a completely intravesical ureterocele. Upper pole partial nephrectomy is the elective treatment for an ectopic ureterocele without preoperative VUR. In an ectopic ureterocele with VUR, no matter which type of primary therapy has been chosen, a secondary procedure at the bladder level, involving ureterocele removal and reimplantation of the ureter(s), should be anticipated. 相似文献

AIM: To determine the long-term results of ureterocele repair, bearing in mind the relative rarity of the malformation, its very polymorphic appearance and the diversity of treatments. MATERIALS AND METHODS: Long-term results were assessed by postoperative follow-up of 126 children with 131 ureteroceles between 1970-2000. RESULTS: With a mean follow-up of 72 months, only 64.2% of children were cured after a one-stage procedure. According to the anatomical type, favourable results were obtained in 81.6% of cases with a single ureter and 57.9% of cases with a duplicated ureter. Treatment success rates for single or duplicated ureters were 73% in the case of intravesical implantation and only 53.9% (34/63 children) in ectopic forms. According to the technique, cure rates were 67.6% after distal incision in 34 children, 61.9% after total nephrectomy or upper pole nephrectomy in 42 children, 50% after ureterocele repair and ureterovesical reimplantation in 20 patients, 75% after total resection of the pathological ureter, parietal reconstruction and ipsilateral and/or contralateral reimplantation in another 20 patients. CONCLUSIONS: A one-stage procedure is only able to cure 2/3 of patients. In view of the tendency to progressive regression of often monstrous distensions during the neonatal period, first-line treatment should consist of a distal incision, followed, in the case of recurrent infections, by partial or total nephrectomy, while reserving the intravesical approach to cases with recurrent pyelonephritis. When this surgery is performed on older children or adolescents, the ureteroceles will be smaller with a lower risk of sphincter damage. 相似文献
