Paraurethral leiomyoma.

Objective: To describe a case of para-urethral leiomyoma and to review the literature.

Methods: The usual preoperative diagnostic procedures and clinical manifestations are discussed.

Results: The mass was resected and, 6 years later, the patient remains asymptomatic and with no recurrence.

GSTT1, GSTM1, and CYP1B1 gene polymorphisms and susceptibility to sporadic renal cell cancer.

Purpose: To estimate the prevalence and importance of GSTT1, GSTM1, and CYP1B1 genotypes in renal cell carcinoma (RCC), and to identify their value as a prognostic factor.

Materials And Methods: Cross-sectional study of a group of patients diagnosed with RCC (n = 133) and a control group (n = 208) with benign conditions and no history of tumor. Controls were selected by cumulative samples and mixed pairing.

Median raphe cyst. Report of two cases and literature review.

Objectives: To report 2 cases of median raphe cysts, 1 in the penis and the other in the perineum.

Method: Two cases of median raphe cyst are described; the first was treated by surgery and the second required no treatment.

Results: The surgical patient experienced no complications and was asymptomatic with no recurrence at 2 years.

[Bellini duct carcinoma: report of two cases].

Objective: We report two cases of collecting duct carcinoma that were diagnosed in our hospital in a six-month period.

Methods/results: The first case was a 75years-old woman showing in CT scan a mass in the left kidney which infiltrated perinephric fat. The second case was a 72-years-old that showed in a CT scan a right renal pelvis lesion, involving inferior vena cava and renal vein.

[Current status of the diagnosis and treatment of Leydig cell testicular tumor. Report of two cases].

Objectives: To review the current diagnosis and treatment of Leydig cell testicular tumors, with special attention to conservative treatment.

Methods: We report two cases of Leydig cell tumor in young adults, diagnosed two years after the appearance of bilateral gynecomastia as first clinical symptom.

Results: One year and eight months after orchyectomy, respectively, clinical symptoms completely disappear in the first case and significantly improved in the second.

Implications of p53 gene mutations on patient survival in transitional cell carcinoma of the bladder: a long-term study.

Objective: To determine the prognostic value of p53 gene mutations and P53 overexpression for predicting the incidence of recurrence, progression and long-term survival of patients with transitional cell carcinoma (TCC) of the bladder.

Methods: Prospective cohort study with 94 consecutive patients diagnosed and treated for TCC. DNA was obtained from tumor tissue to perform PCR-SSCP of p53 exons 5-9, with automatic sequencing of any mutated samples.

Sensitivity and specificity of p53 protein detection by immunohistochemistry in patients with urothelial bladder carcinoma.

Objective: To analyze the correlation between the genotypic and phenotypic patterns of p53 in patients with transitional cell carcinoma (TCC) of the urinary bladder.

Materials And Methods: Cross-sectional study of 73 patients diagnosed with TCC. DNA was obtained from the tumor tissue to perform polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) of exons 5-9 of the p53 gene, with automatic sequencing done on any mutated samples.

[Voiding symptoms changes after vaginal sling surgery for female stress urinary incontinence].

Objectives: To evaluate the changes in voiding symptoms in female patients with stress urinary incontinence (SUI) undergoing transvaginal sling techniques over a five-year period in the Department of Urology at the University Hospital of Albacete.

Methods: Between November 2001 and December 2005 126 patients with SUI (mean age 57.09 years; 36-78) underwent transvaginal sling techniques (Sling in Fast, TVK TOT).

Isolated testicular polyarteritis nodosa.

Isolated polyarteritis nodosa is a rare condition that may be triggered by local exposure to certain agents capable of provoking local immunostimulation without a systemic immune reaction. Isolated polyarteritis nodosa in the testes presents similar histologic characteristics as those of systemic inflammation, although infarcted areas in the testis are more common in generalized polyarteritis nodosa. Definitive diagnosis requires histologic study.

Obstructive uropathy secondary to ureteral herniation in a pediatric en bloc renal graft.

Ureteral herniation is a rare entity. We report the first case of extraperitoneal ureteral herniation in a pediatric en bloc renal graft causing obstructive uropathy. A 70-year-old, obese patient with an en bloc renal transplant was found to have ureterohydronephrosis in the right renal graft on magnetic resonance imaging.

[Large retroperitoneal malignant fibrohistiocytoma: report of one case].

Objectives: To report one case of a large retroperitoneal malignant fibrohistiocytoma.

Methods/results: 40-year-old female with the diagnosis of a large right retroperitoneal mass after a study for right flank pain and weight loss over several months. Surgery was performed with excision of a large tumor; the pathologic diagnosis was malignant fibrohistiocytoma.

[Complications after radical cystectomy in patients with bladder carcinoma].

Objective: To describe the frequency and type of complications after radical cystectomy for cancer of the urinary bladder and their relationship with the different types of urinary diversion techniques utilized.

Methods: We conducted a retrospective study of 166 patients who underwent radical cystectomy in the same department of urology over a period of 12 years. The intraoperative, early, late complications and the need for postoperative treatments are analyzed according to percentages, main trends, scatter and confidence interval.
