Contractile responses of urinary bladder in an experimental model of chronic renal failure.

Chronic kidney disease is a public health problem with increasing prevalence caused by diabetes, hypertension and glomerulonephritis. Number of publications investigate the lower urinary tract dysfunction due to CKD is limited. There is a high incidence of bladder dysfunction of different degrees in patients with renal failure.

Alterations in promoter methylation status of tumor suppressor HIC1, SFRP2, and DAPK1 genes in prostate carcinomas.

Hypermethylated genomic DNA is a common feature in tumoral tissues, although the prevalence of this modification remains poorly understood. We aimed to determine the frequency of five tumor suppressor (TS) genes in prostate cancer and the correlation between promoter hypermethylation of these genes and low and high grade of prostate carcinomas. A total of 30 prostate tumor specimens were investigated for promoter methylation status of TS hypermethylated in cancer 1 (HIC1), death-associated protein kinase 1 (DAPK1), secreted frizzled-related protein 2 (SFRP2), cyclin-dependent kinase inhibitor 2A (p16), and O-6-methylguanine-DNA methyltransferase (MGMT) genes by using bisulfite modifying method.

Combined point mutations in codon 12 and 13 of KRAS oncogene in prostate carcinomas.

Prostate cancer is a common malignancy that develops by structural mutation(s) and/or other genetic alterations in specific genes.The G to T transversions in codon 12 and C to T transitions in codon 13 of KRAS proto-oncogene are predominant point mutations that occur in about 20% of different cancers in human. In the current study it was aimed to investigate the prevalence and predictive significance of KRAS mutations in patients with prostate carcinomas.

Effect of angiotensin-converting enzyme inhibition and angiotensin II type 1 receptor blockade on apoptotic changes in contralateral testis following unilateral testicular torsion.

Objectives: In this experimental study, our aim was to determine whether angiotensin-converting enzyme (ACE) inhibition and angiotensin II type 1 (AT1) receptor blockade affect the apoptotic changes in contralateral testis following unilateral testicular torsion (UTT).

Methods: Study groups consisted of 30 adult male Wistar rats. The rats were randomly separated into five groups.

A comparison of sedation with dexmedetomidine or propofol during shockwave lithotripsy: a randomized controlled trial.

Background: Dexmedetomidine, because it has both sedative and analgesic properties, may be suitable for conscious sedation during painful procedures. Extracorporeal shockwave lithotripsy (ESWL) is a minimal to mildly painful procedure that requires conscious sedation. We thus evaluated the utility of dexmedetomidine compared with propofol during an ESWL procedure.

Comparison of CT-guided sclerotherapy with using 95% ethanol and 20% hypertonic saline for managing simple renal cyst.

Objective: We wanted to compare the efficacies of 95% ethanol and 20% hypertonic saline (HS) sclerotherapies that were performed in a single session under CT guidance for the management of simple renal cysts.

Materials And Methods: A prospective series of 74 consecutive patients (average age: 57.6 +/- 8.

Efficacy of tolterodine as a first-line treatment for non-neurogenic voiding dysfunction in children.

Objective: To assess the effect of antimuscarinic treatment with tolterodine combined with behavioural modification as a first-line treatment, before invasive investigation, in children with non-neurogenic voiding dysfunction but no obvious anatomical or neurogenic cause.

Patients And Methods: The study comprised 44 children presenting with voiding dysfunction (30 girls and 14 boys, mean age 7 years, range 5-14); all had a noninvasive evaluation consisting of a history, urine analysis, renal and bladder ultrasonography and physical examination, with specific emphasis on the voiding pattern. Anticholinergic treatment with tolterodine (1 mg twice daily) was started in all patients; they were also informed about conservative management, including timed voiding, double voiding and relaxation of the pelvic floor during voiding.

Comparison of outcomes of three different surgical techniques performed for stress urinary incontinence.

Background: The aim was to compare the efficacy of Burch colposuspension, transvaginal four-corner bladder neck suspension (FCBNS) and the vaginal wall sling (VWS) procedures in patients with stress urinary incontinence.

Methods: A retrospective analysis was performed on 88 patients who underwent Burch colposuspension (n = 20), FCBNS (n = 29) and VWS (n = 39) for stress urinary incontinence. Objective and subjective cure rates at 3 months and annually after the operation were the primary outcome measures.

[Surgical treatment of penil fractures].

Background: Patients diagnosis as penil fracture and treated with surgical methods were evaluated retrospectively between January 1990-February 2002.

Methods: Patients were evaluated by age, trauma type, time passed after the trauma, physical examination and radiologic data.

Results: The cause of trauma was blunt trauma in all patients.

Genitourinary tuberculosis: a review of 174 cases.

In 174 cases of genitourinary tuberculosis diagnosed and treated in our clinic we evaluated, retrospectively, age and sex distributions, symptoms, physical and laboratory findings, primary focus, surgical and medical treatments. Flank pain and non-specific urinary complaints, e.g.
