Sodium hyaluronate in treatment of diffuse nephrogenic adenoma of the bladder in a child.

Nephrogenic adenoma is a rare, benign lesion of the bladder, occurring as an epithelial response to chronic infection or trauma, probably arising from nephrogenic metaplasia. In contrast to nephrogenic adenomas in adults, who present with this tumor in the entire ureteral tract, it has been observed exclusively in the bladder of children thus far. We report and discuss here the case of a 12-year-old boy with diffuse calculus-producing nephrogenic adenoma successfully treated with sodium hyaluronate.

The use of the Limberg skin flap for closure of large lumbosacral myelomeningoceles.

Closure of the skin defect in myelomeningocele repair is an essential step that determines the quality of the surgical result. In large myelomeningoceles, however, adequate skin coverage may not be accomplished by direct closure or skin undermining. In such cases, the skin defect is best repaired using flaps.

Coexisting pelviureteral and vesicoureteral junction obstruction in children.

Objective: To address reasons for diagnostic failure in children with coexisting pelviureteral and vesicoureteral junction obstruction.

Patients And Methods: A total of 11 children with coexisting pelviureteral and vesicoureteral junction obstruction are reported. This anomaly was recognised at presentation in only 5 (45%) of cases.

[Antibiotic prophylaxys in pediatric surgery of genito-urinary abnormalities].

Ninety-two patients in the age range of 2,5 and 16 years with hypospadias (28 cases), vescicorenal reflux (22 cases), hydronephrosis (16 cases) and a series of other congenital genitourinary abnormalities underwent one or more surgical interventions performed by an unique surgeon at the department of Pediatric Surgery, S. Bortolo Hospital, Vicenza. The more frequently performed interventions were the plastic of the urethra (28 pts, 30,4%), that of the pyeloureteral joint (15 pts, 16,3%) and the modelling and the reimplantation of the ureter/ureters (12 pts, 13%).

Successful use of transureteroureterostomy in children: a clinical study.

The purpose of this review of patients was to look at the current role of transureteroureterostomy in children. In addition, this study should give an indication of the long-term safety of transureteroureterostomy in children with neurogenic bladder. From 1972 on, 70 subjects between the ages of 2 and 13 underwent transureteroureterostomy.

Relevance of infection in children with urachal cysts.

Objective: To assess the role of infection in the management of children with urachal cysts.

Methods: A retrospective study on 10 children with urachal cysts operated on over an 11-year period (from 1987 to 1998) was performed. Uncomplicated urachal cysts were found in 2 children who underwent primary cyst removal.

Ureterovascular hydronephrosis in children: is pyeloplasty always necessary?

Objective: To evaluate the efficacy of the vessel transposition technique in ureterovascular hydronephrosis in children.

Methods: Over a 25-year period, we treated 111 patients with 112 instances of ureterovascular hydronephrosis. In order to determine the obstructive effect of the vessels, we performed an intraoperative diuretic test.

Fatal cardiac tamponade as a late complication of central venous catheterization: a case report.

Central venous catheterization is a reliable technique in neonatal surgery. Nevertheless, the rate of mechanical catheter-related complications remains high. We report a neonate with gastroschisis in which the successful placement of a central venous catheter was followed later by a cardiac tamponade with a fatal outcome.

Endoscopic and minimal open surgical incision of ureteroceles.

Ureterocele decompression by endoscopic or open incision was the primary treatment in 59 children with 63 ureteroceles. Of these, 18 were intravesical and 45 were ectopic. The endoscopic or open incision adequately decompressed all intravesical ureteroceles and 37 of 45 ectopic ureteroceles (82%).

Blue venography in adolescent varicocelectomy: a modified surgical approach.

Background/purpose: Conventional varicocelectomy is often complicated by postoperative recurrences. When failure occurs, it is likely to be caused by incomplete interruption of the testicular vein, which is divided into multiple branches, or by the parallel collaterals, and to incompetence of the cremasteric vein(s). Occasionally it is caused by reversed flow in the deferential vein(s).

[Portable bladder ultrasonography: a new technic for the urological management of pediatric spinal cord damage].

Noninvasive measurement of bladder volume demonstrates how a new technology can improve the management of pediatric patients with spinal cord injured. The bladder-scan was used to perform volume and post-void residual urine measurement. The aim of our study is to verify the reliability of Bladder Manager Tc 5000 in these patients.

Labial skin-flap vaginoplasty using tissue expanders.

In severe vaginal malformations, when the distance between the upper vaginal pouch and perineum is too long (6 cm or more), reconstruction of the vagina can be performed by colonic interposition or by long cutaneous flaps obtained by the tissue expansion technique. Two female adolescents were treated using expanded labial skin flaps. Dissection and anastomosis between the vaginal remnant and cutaneous tube was performed by the transtrigonal approach.

[Severe chronic constipation: limitations of medical therapy and indications for surgical intervention. II].

Severe chronic constipation is a common problem in children. Most patients have functional constipation, only few (approximately 5%) have an underlying organic disease who requires surgical treatment. Anatomic problems with a painful defecation (anal rhagades, fistulas, hemorrhoids) or with difficult defecation (anal stenosis, tumor) require only a careful physical examination.

[Non-palpable testis: modern diagnostic and therapeutic trends].

Management of the nonpalpable testis is controversial and can be difficult as shown by the multiple modalities for evaluation and proposed treatment. In our opinion, laparoscopy is the ideal first step in the management of patients with a nonpalpable testis, having a great reliability in locating or confirming absence of an occult testis. Accurate preoperative assessment and localization will assist in selecting the appropriate surgical approach either laparoscopic, laparoscopic-assisted, or open procedure.
