Aim: To investigate the prognostic significance of certain clinical and pathological factors of renal cell cancer.

Materials And Methods: One hundred and fourteen patients who underwent radical nephrectomy between 1996 and 2011 in our hospital were examined. Parameters including age, gender, mode of presentation, hematological and pathological parameters were evaluated for their role as predictors of disease-free and overall survival.

The aim of the study was to investigate the results of bladder irrigation with Water for Injection (WFI) after transurethral resection of bladder tumours for comparison with those for adjuvant use of BCG. A total of 239 patients (158 with single tumours, group A, and 81 with multiple tumours, group B) received continuous intravesical postoperative irrigation with WFI. Some 128 patients received intravesical irrigation with WFI, followed by weekly instillations of BCG (group C).

Purpose: To evaluate the effectiveness of Otis urethrotomy combined with six weekly urethral dilations until 40 French (Fr) in the treatment of women with urodynamic diagnosis of bladder outlet obstruction (BOO).

Materials And Methods: Women diagnosed with lower urinary tract symptoms underwent urodynamic evaluation. Severity of symptoms and quality of life were assessed with international prostate symptom score (IPSS) and quality of life (QoL) questionnaires.

Objective: We investigated the expression of thymidine phosphorylase (TP) in bladder carcinomas and assessed its prognostic significance in superficial bladder cancer samples.

Patients And Methods: We studied 142 primary bladder cancer samples immunohistochemically for nuclear thymidine phosphorylase (TPN), cytoplasmic (TPC) and stromal (TPSTR) expression. We correlated them with standard clinicopathological features (grade, stage, concurrent in situ, multiplicity, primary or recurrent status), as well with recurrence and progression.

Objective: To assess the prognostic significance of angiogenesis parameters such as microvessel density (MVD) and vascular endothelial growth factor (VEGF) in superficial bladder cancer.

Patients And Methods: We studied 127 superficial bladder cancer samples immunohistochemically for the above factors. We compared them with standard clinicopathological features (grade, stage, concurrent in situ, multifocality, primary or recurrent status) as well as with p53 expression, recurrence and progression to muscle infiltrating disease.

Introduction: The expression pattern of cyclins D1 and E, as well as cyclin-dependent kinase inhibitors p21(Wa1/Cip1) and p27(Kip1) and their relationship to tumour behaviour and patients' prognosis was examined in 142 urothelial cell carcinomas. The expression of these proteins was also analyzed along with other cell-cycle-related proteins such as: p53, pRb and the proliferation-associated indices Ki-67 and proliferating cell nuclear antigen (PCNA).

Patients And Methods: These molecule markers were localized immunochemically using the monoclonal antibodies anti-cyclin D1 (DCS-6), anti-cyclin E (13A3), anti-p21 (4D10), and anti-p27 (1B4) in 142 patients with urothelial cell carcinoma.

Preperitoneal inguinal herniorraphy in conjuction with other pelvic procedures has been described in the literature, but it has not gained wide popularity mainly due to the high recurrence rate. Recently, there has been a resurgence of interest in the preperitoneal repair of inguinal hernias with the application of mesh on the deficiency of the inguinal wall using the method commonly known as the Stoppa procedure. We evaluated the results and complications of 22 patients who underwent open surgical prostatectomy (adenomectomy) and simultaneous preperitoneal application of polypropylene mesh.

Background: Although tumor grade and stage are the most accurate prognostic factors in the evaluation of transitional cell bladder cancer, they cannot always predict the true tumor biological potential since superficial tumors of the same stage and grade may have completely different clinical courses. This study was performed in order to examine whether p53, bcl-2 and Ki-67 have any validity in predicting the course of superficial bladder tumors, with high risk for recurrence or progression, over the traditional prognostic factors that are currently used. Furthermore, we investigated whether any one of these markers maintains its prognostic capability after one course of intravesical instillations of IFN gamma.

Objective: The purpose of this study was to assess the significance of the standard CD44 adhesion molecule expression in predicting progression of high risk superficial bladder carcinoma in the short term.

Methods: Sixty-six patients (51 males and 15 females, aged 27 to 89 years (mean 64.75 years) with primary superficial transitional cell bladder cancer initially treated with transurethral resection (TURBT) were enrolled in the study.

Objective: To determine if intravesically administered recombinant interferon (IFN) gamma may serve as adjuvant first line treatment in prophylaxis of superficial bladder cancer by reducing its risk for recurrence, in the short term.

Material And Methods: A total of 54 patients (43 males and 11 females) with superficial bladder tumours (Ta/T1) initially treated with transurethral resection for their tumors were randomized into two groups: Twenty-eight patients were left untreated after the transurethral resection (controls) whereas 26 patients received intravesical IFN gamma adjuvantly, at a dosage of 0.7 mg per week for 8 weeks.

This study was conducted to examine the effect of height and weight on the incidence of varicocele in schoolboys aged 5-16 years and the impact of varicocele on testicular size. Genital stage, height, weight, varicocele grade, and testicular size were recorded for 3047 school boys who were clinically examined while standing by a specialist in urology. Left varicocele was detected in 98 of the boys who were all aged 9-16 years.

Background: The infiltration of muscularis mucosa in superficial bladder cancer has been reported to be predictive of an unfavourable course of the disease.

Materials And Methods: We studied immunohistochemically Ki-67, PCNA and p53 tumour markers in 68 P1a and Pib bladder tumours.

Results: A statistically significant difference (p = 0.

Background: Although the antiproliferative activity of interferon gamma has been reported in various tumours, this has not been studied in bladder cancer. Proliferative cell nuclear antigen and Ki67 growth fractions were estimated in this study in superficial bladder cancer, as a measure of the antiproliferative effect of interferon gamma.

Materials And Methods: Superficial bladder cancer samples before and after four weekly intravesical instillations of 0.

Background: The investigation of relationship of tumour biological activity and the degree of tissue infiltrating lymphocytes (T4, T8, T6) and macrophages in bladder cancer was the purpose of this study.

Materials And Methods: Tumour specimens and near and distant biopsies from 26 patients suffering from superficial bladder cancer and bladder biopsies from 6 controls were studied. Monoclonal antibodies against T helper/inducer, (CD4), T suppressor/cytotoxic (CD8), Langerhans cells (CD1a) and Monocytes/Histiocytes (LeuM5) were used for the detection of lymphocyte subpopulations.

Predicting future tumour behaviour has always been a major task when treating bladder cancer. Ki67 monoclonal antibody has been reported to be a good marker of proliferative activity in a variety of tumours. We have studied the association of growth fractions defined by the monoclonal antibody with tumour grade, category and recurrence rate of superficial lesions in 34 patients with bladder cancer and 15 normal controls.
