TFE3 Translocation-Associated Renal Cell Carcinoma Presenting as Avascular Necrosis of the Femur in a 19-Year-Old Patient: Case Report and Review of the Literature.

In the United States, renal cell carcinoma (RCC) accounts for approximately 3% of adult malignancies and 90-95% of all neoplasms arising from the kidney. According to the National Cancer Institute, 58 240 new cases and 13 040 deaths from renal cancer will occur in 2010. RCC usually occurs in older adults between the ages of 50 and 70 and is rare in young adults and children.

Urologic manifestations of postpolio syndrome.

To determine the character and prevalence of bladder dysfunction among persons with a history of polio, we conducted a survey of randomly selected polio survivors. The survey solicited information on the acute episode of polio and the nature of late-onset neurologic symptoms that could be attributed to postpolio syndrome. There were 242 female and 88 male respondents to the study.

Combined Leydig cell and Sertoli cell dysfunction in 46,XX males lacking the sex determining region Y gene.

We have evaluated 3 individuals with a rare form of 46,XX sex reversal. All of them had ambiguous external genitalia and mixed wolffian and müllerian structures, indicating both Leydig cell and Sertoli cell dysfunction, similar to that of patients with true hermaphroditism. However, gonadal tissue was not ovotesticular but testicular with varying degrees of dysgenesis.

Epidermoid cysts of testes and role of sonography.

Four patients with histologically proved epidermoid cysts of the testicle were managed with radical orchiectomy. High-resolution testicular sonography demonstrated similar findings in all cases, but these findings were not specific and did not preclude other malignant or teratomatous lesions. The lack of both unique clinical features and specific sonographic findings would suggest that extreme caution must be used if wedge resection or enucleation is contemplated for a patient with presumed epidermoid cyst.

The effects of ileocystoplasty on the development of renal failure in a rat model 5/6 nephrectomy.

We examined the effects of ileocystoplasty on renal function and bone mineral content in 160 juvenile male Wistar-Furth rats with and without renal insufficiency induced by 5/6 nephrectomy. At intervals up to 20 weeks blood, bone and kidney samples were obtained with the animals under anesthesia and then they were sacrificed. Serum parameters of renal function and calcium metabolism were measured.

Management of pregnancy after major urinary reconstruction.

Major reconstructions of the urinary tract are being performed with increasing frequency. However, published experience concerning pregnancy after urinary reconstruction is limited. Complications in women who have undergone such complex procedures may endanger them or their fetuses and can disrupt the reconstruction or impair renal function.

Experience with single stage hypospadias reconstruction.

Our experience with single stage primary hypospadias repair in 96 patients over a 12-month period is reviewed. The ages ranged from 7 months to 14 years with an average of 3.5 years.

Surgical approaches to block dissection of the inguinal lymph nodes.

Block dissection of the inguinal lymph nodes is associated with a high incidence of complications, the most frequent of which are related to wound healing. To determine the optimal surgical approach, a review of our experience over the last 10 years was undertaken. Fifty inguinal lymph node dissections are presented.

Transuretero-ureterostomy--a review of its use in modern paediatric urology.

Transuretero-ureterostomy (TUU) was performed on 55 patients with a mean age of 10 years at operation and a mean follow-up of 4 years. The indications for this procedure are described and, if followed, it is safe and easily performed. The indications for its use may be as a primary procedure for unilateral ureteric pathology, as a salvage procedure, after failed ureteric reimplantation or as part of a urinary undiversion.

Testicular torsion: management with ultrasonic Doppler flow detector.

The use of the ultrasonic Doppler flow detector in the management of acute testicular torsion is described. The Doppler can be used to diagnose torsion accurately and also to monitor manual detorsion. In this series detorsion was a reliable procedure which avoided emergency exploration in 5 of 8 patients with acute torsion.

Behçet disease with genitourinary involvement treated with colchicine.

A case report of Behçet disease is presented. Resolution was obtained with colchicine. The urologic implications of this disease and its treatment are discussed.

The persisting mesonephric duct syndrome: the description of a new syndrome.

Persistence of the mesonephric duct is a well recognized but uncommon abnormality that results in vasoureteral fusion. This anomaly may be accompanied by rectal malformations and disturbances of renal ascent or morphology. The literature on persistence of the mesonephric duct was reviewed and the data were correlated with our understanding of embryogenesis in an attempt to understand the relationship between these seemingly unrelated anomalies.

Ureterovesical fistula: an unusual complication of ureteral reimplantation.

A case of a ureterovesical fistula secondary to ureteral reimplantation is presented. The factors that may have contributed to formation of the fistula are discussed, and the diagnosis and management of this complication are reviewed.
