Objectives: The aim of this study was to evaluate serum C-reactive protein (CRP) concentration in patients with bladder cancer, as well as to determine its potential role as biomarker in the differentiation of different stages of the disease. Methods: The study included 90 patients with bladder carcinoma who were divided into 3 groups: 30 patients with non-invasive, superficial (Ta), 30 patients with superficial (T1), and 30 patients with invasive (T2-T4) bladder cancer. Serum CRP level was determined by laser nephelometry. Results: Serum CRP levels in T2-T4 group of patients was 8.65 (3.20-18.20) mg/dL and significantly higher compared to the serum CRP level in Ta group of patients (1.55 (0.67 - 3,35) mg/dL; p<0.005), T1 group (1.90 (1.27-7.20) mg/dL, p=0.006) and compared to the control group of patients (1.20 (0.90-2.10) mg/dL; p<0.005). Multiple linear regression revealed that serum CRP level was independently associated with the tumor size (β = 0.376; p<0.001). There was an independent positive association between CRP and high progressing potential of the bladder cancer. Conclusion: CRP might have a significant role as a biomarkerin the diagnosis of this disease, with special attention on its potential role in differentiating different stages of the disease.

AIM To determine the influence of independent predictors (nuclear grade, patient’s general condition, tumor size) on survival of patients suffering from renal cancer. METHODS The study included 158 patients treated for renal parenchymal carcinoma in the period between 01. 01. 1998 and 31. 12. 2011. The patients' general condition was evaluated using the ECOG staging system. Nuclear grade (NG) was assessed by the Fuhrman criteria. Prognostic factors were tested applying the Cox regression analysis and based on the significance independent predictors were determined. RESULTS The total survival rate of patients with renal parenchymal carcinoma was 81.2% after one year, 77.6% after 5 years and 70.4% after 10 years. In patients with NG 1 the survival rate after 5 years was 100%, whereas the survival in patients with NG2, 3 and 4 was 98%, 48% and 0%, respectively. The survival rate in patients with ECOG 0 and 1 after 5 years was 100%, while in patients with ECOG 2 and 3 stage of the disease the survival rate was 68% and 25%, respectively. In patients with a tumor node less than 40 mm, ten-year survival rate was100%, whereas the ten-year survival rate in patients with the tumor node sized 40 to 70 mm was 87%, and in patients with the tumor node over 70 mm ten-year survival rate was 66%. CONCLUSION Multivariate analysis has established that the size of the tumor node, patient's general condition and nuclear grade are independent predictors of disease outcome.

AIM To determine an influence of dependent predictors (clinical presentation, stage, pH type) on survival of patients suffering from renal carcinoma. METHODS The research included 158 patients who had been treated for carcinoma of renal parenchyma in the period between 1 January 1998 and 31 December 2011. A disease stage was determined according to the guidelines of the American Joint Committee on Cancer (AJCC). Prognostic factors were tested by the Cox regression analysis, and dependent prognostic factors were determined based on significance. RESULTS Patient survival was significantly different in relation to the clinical presentation of the disease (p less than 0.0001). Length of patient survival significantly differs with regard to the clinical stage of the disease (p less than 0.0001). The length of patient survival significantly differs depending on a pathohistological type of cancer (p=0.0027) and after five years it was much longer for patients with the conventional cancer type as compared with the chromophobe type, 80.3% vs. 61.5%, respectively. The total survival rate of patients with renal parenchymal cancer is 81.2% after one year, 77.6% after 5 years and 70.4% after 10 years. CONCLUSION The manner of detection, clinical stage and pathohistological type of the disease did not meet requirements for independent predictors. Success of the therapeutic treatment depends on the manner of the renal cell carcinoma presentation, pathohistological type and tumor stage.

Objectives: To determine the optimal medication for the treatment of renal colic using evidence based medicine (EBM) parameters (RR, ARR, NNT, NNH, ARI, RRI). Sample and Methodology: During 2010, an ITT study was conducted on 400 outpatients of the Sarajevo University Clinical Center Urology Clinic in order to investigate renal colic pain relief drugs. Each group consisting of 100 patients was administered either Metamizol amp. i.v., or Diclofenac amp. i.m., or Butylscopolamine amp. i.v., while 100 patients belonged to the placebo group that was given distilled water (aqua redestilata). All patients completed visual analogue pain scale (VAPS) from 0 to 10 prior to and after the treatment. Results: Using EBM parameters Diclofenac Na and Metamizol were shown to be the most efficient in the treatment of renal colic. In these two groups, relative risk (RR) was 21 and 8,5% respectively; Absolute Risk Reduction (ARR) was 74 and 86% respectively, and Number Needed to Treat (NNT) was 1 for both groups, while chi-squared (X2) test has shown that there is no statistically significant difference between these two drugs when it comes to their effect. In the Butylscopolamine group, RR was 81; ARR 18%, while NNT was 5. With respect to side effects, only in his group it was shown that Relative Risk Increase (RRI) was 84, ARI 83%, while Number Needed to Harm (NNH) was 2. Conclusion: The most optimal medication for the treatment of renal colic according to EBM parameters is Diclofenac Na, followed by Metamizol. Butylscopolamine is not recommended for the treatment of renal colic.

OBJECTIVE To determine the correlation of intravesical prostatic protrusion (IPP) and bladder wall thickness (BWT) with clinical and urodynamic parameters, as well as their sensitivity and specificity with regard to bladder outlet obstruction in patients with a benign prostatic enlargement (BPE). MATERIALS AND METHODS 111 patients with lower urinary tract symptoms and confirmed BPE completed the International Prostatic Symptom Score (I-PSS), as well as a transabdominal ultrasound to determine their prostate volume, a grade of IPP and BWT. All the patients were then subjected to the complete urodynamic studies (UDS). RESULTS The IPP showed a good correlation with the prostate volume (r = 0.61) and serum PSA (r = 0.48); p = 0.0000, free uroflowmetry (r = -0.27; p = 0.004), as well as the determinants of urodynamic obstruction: bladder outlet obstruction index-BOOI (r = 0.36; p < 0.0001), and ICS and Schaefer obstruction class nomograms (rho = 0.33 and rho = 0.39, respectively; p < 0.001), while the BWT showed only a statistical correlation with age (r = 0.23; p = 0.02) and serum PSA (r = 0.4; p = 0.0000), regardless of an significant correlation with the IPP (r = 0.45; p = 0.0000). The ANOVA test showed a significant difference between the IPP grades for the observed clinical and urodynamic variables with an increase in significance for IPP>10 mm. The area under the ROC curve in the prediction of obstruction for the IPP is 0.71 (sensitivity 59.6, specificity 81.4), while the AUC for the BWT is 0.61 (sensitivity 64.5, specificity 59.2). The stepwise logistic regression model shows that most significant independent variables for the obstruction are the IPP, Q(max) free and age, with the area under the ROC curve of 0.78 (95% CI 0.695 to 0.856). CONCLUSION The IPP higher than 10 mm as a non-invasive predictor of infravesical obstruction shows good correlations with clinical and urodynamic parameters, while the specificity and PPV against obstruction are significant. Despite a good correlation with IPP, the BWT is only a modest indicator of obstruction.

AIM Establish the main differences in the prostate volume, prostate specific antigen density (PSAD), number of biopsy samples in patients with primarily or rebiopsy detected prostate cancer. MATERIALS AND METHODS In the 2007-2009 period, at the KCUS Urology Clinic, there were 379 TRUS guided prostate biopsies in 323 patients with known prostate volume. The total of 56 patients (17.3%) underwent the first rebiopsy, primarily due to precancerous lesions. The mean prostate volume, ranges of prostate size, PSAT, PSAD and the number of biopsy samples were analysed retrospectively, and the main characteristics in patients with primarily and rebiopsy diagnosed Pca were evaluated as well. RESULTS The first biopsy cancer detection rate was 29.6% (112/379). The rebiopsy detection rate was 30.3%. There was no statistically significant difference in the prostate volume and the number of biopsy samples among the total number of patients with prostate cancer against the group with benign (suspected) findings. There was a higher Pca detection rate in patients with the prostate volume < 40 cm3 and 40-60 cm3, against the group with the prostate volume > 60 cm3. PSAD was significantly higher in patients with PCa (0.24 vs. 0.18; p = 0.013). The total of 27.2% of the patients with negative biopsy findings and 48% of the patients with diagnosed Pca had PSAD > 0.15. PSAD showed sensitivity and specificity in prostate cancer detection of 50% and 75%, with PPV of 48%. Furthermore, the patients with PSAD >0.15 had a higher Gleason score versus the patients with PSAD < 0.15 (6.7 +/- 2.4 vs. 5.9 +/- 1.7; p < 0.003). A comparison of the main characteristics in patients with primarily and rebiopsy detected prostate cancer gave a statistically significant difference only in the number of biopsy samples (10.9 vs. 14.1, p <.0000). CONCLUSION Patients with a smaller prostate volume, lower PSAD and a higher number of biopsy samples in rebiopsy have a higher chance of prostate cancer detection. PSAD carries a higher specificity in rebiopsy decision, and a higher PSAD is related to a higher Gleason score.

High grade prostatic intraepithelial neoplasia (HGPIN) is widely regarded as the precancerous. The aim of this study was to determine PSA related parameters in patients with initial PSA values 2-10 ng/mL and diagnosis of HGPIN without finding carcinoma at the time of their first needle biopsy. Study groups consisted of 100 men who were diagnosed HGPIN, 84 with cancer and 183 with benign hyperplasia on first biopsy of prostate. Total PSA and free PSA were measured and ratio free/total PSA and PSA density calculated. Mean values of these parameters were compared, and receiver operating characteristic curves were used for comparison of PSA related parameters to discriminate groups of patients.Total PSA, free PSA level and PSA density in patients with HGPIN (6.388 ng/mL) did not differ significantly compared to prostate carcinoma (6.976 ng/mL) or benign prostatic hyperplasia (6.07 ng/mL) patients. Patients with HGPIN had significantly higher ratio free/total PSA than those with prostate carcinoma (0.168 vs 0.133), but significantly lower than patients with benign prostatic hyperplasia (0.168 vs 0.185). Ratio of free/total PSA significantly discriminate HGPIN from prostate carcinoma with sensitivity 84.52 and specify 45.00 at cut-off point of ≤ 0.18. Values of PSA, free PSA and ratio free/total PSA in cases of HGPIN appear to be intermediate between prostate cancer and normal levels. Ratio of free/total PSA may help in decision to repeat biopsies in the presence of HGPIN on biopsy, without concomitant prostate cancer, in patients suitable for curative treatment, with normal digito-rectal examination and trans-rectal sonography.

OBJECTIVE Establish the prostate cancer (PCa) detection rate and the premalignant lesion incidence, as well as their importance in cancer detection at the first rebiopsy. MATERIALS AND METHODS In the period 2006-2008, at the CCUS Urology Clinic, there were 585 prostate biopsies performed in 515 patients. 12% of the patients underwent the first biopsy due to premalignant lesion findings. The main characteristics of the patients--age, prostate specific antigen (PSAt)-total and PSA ratio (PSAr), the number of needle biopsies, Gleason score and the role of premalignant lesions in diagnosis of PCa at the first rebiopsy were processed retrospectively. RESULTS Primarily detected PCa amounted to 32.4% (167/515), while the rebiopsy showed the detection rate of 35.7% (25/70). No statistically significant age or PSAt and PSAr difference was observed, while there was, however, a difference in the number of biopsy samples, 11 (6-18) vs. 12 (8-20) and in the Gleason score (6.5 vs. 5.9) among the observed groups (p < 0.05). Atypical small acinar proliferation (ASAP) and high grade intra epithelial neoplasia (HGPIN), were found in 4.95% and 7.2% of the cases, while the ASAP + HGPIN combination was found in 1.5% of the cases. The PCa detection rate at the first rebiopsy in patients with ASAP, HGPIN and ASAP + HGPIN lesions was 50%, 23.6% and 50%, respectively. The ANOVA test showed a statistically significant shorter time period for rebiopsy in ASAP+HGPIN patients than that of patients with ASAP and HGPIN lesions. CONCLUSION A repeated positive biopsy establishes PCa in patients with lower PSAt values and the Gleason score, which is followed by an increased number of biopsy samples. ASAP and ASAP + HGPIN lesions carry a higher specificity of75% and 91%, respectively, while the PPV in prostate cancer detection for HGPIN is low (24%).

UNLABELLED Purpose of the research is to establish which clinical and biopsy parameters could predict extra-capsular spread of prostate carcinoma for 2-10 ng/ml PSA values, in patients submitted to radical retropubic prostatectomy. METHODOLOGY In the period of 30 months, 80 patients were treated with radical retro-pubic prostatectomy with bilateral pelvic lymphadenectomy, for whom clinical, biopsy, radiological and biochemical analysis were positive to organ limited tumor. Serum PSA, fpsa/tpsa, PSAD,values are evaluated, and other parameters as number of positive biopsies, percentage of positive biopsies, localization of positive biopsies, and perineural invasion and biopsy Gleason score. RESULTS from total number of 80 patients with 2-10 ng/ml PSA, 7 (9%) patients had extra-capsular spread of prostate carcinoma. Upon using multivariate regression analysis, following parameters were proved as significant predictors of extra-capsular spread: biopsy Gleason score, number of positive biopsy samples and invasion, while serum PSA, FPSA/TPSA ratio, PSAD, prostate age and volume have not shown as significant predictors for extra-capsular extension. CONCLUSION Biopsy GS, perineural invasion and number of biopsy samples are statistically significant predictors of extra-capsular spread of prostate carcinoma for 2-10 ml PSA. Percentage of positive biopsies, tumor length in a sample and the localization of positive biopsies are on the borderline of statistical significance and as such should be taken into consideration.

BACKGROUND Prostate specific antigen (PSA) has significance in diagnostics of the prostate cancer, establishing stage of the disease and follow up of results of the treatment with different methods. Increased PSA levels in serum is not characteristic only for persons who have prostate cancer but also of those with benign conditions, especially in range of 4.0 ng/mL to 10.0 ng/ml, where we see a lot of results superposition. Marker determination of free and total PSA-ratio FPSA/TPSA and total PSA and prostate volume--PSA density was introduced for improvement of the sensitivity of PSA. Purpose is to analyze demonstrators of the concentration of PSA and its fraction in patients with histologically confirmed and radically removed prostate cancer, and to establish its correlation with advancement and differentiation of the disease. WORK METHOD The investigation was done in 80 patients with histologically confirmed, prostate cancer clinical stage T1-2, NO, MO, initial PSA level of 2-10 ng/ml and performed radical prostatectomy. RESULTS Out of 80 patients, 6 of them (9%) had total serum PSA level within referral values (<4 ng/ml). There were 55 patients (68%) with values of ratio FPSA/TPSA from 0 to 0.15, 18 (23%) patients had values between 0.16-0.19 and 7 (9%) patients had values above 0.20 ratio FPSA/TPSA. Fifty patients (62%) had PSA density in values to 0, 15, and 30 patients (38%) had values above 0.15. According to completed multiple regression analysis values of PSA, ratio FPSA/TPSA and PSA density had no statistically significant correlation with extra-capsular invasion and lymphatic metastasis, which points out that as it is, they do not contribute to its prediction. CONCLUSION Significant number of patients with histologically proven and radically removed prostate cancer had serum PSA level within normal referral values. PSA density and ratio FPSA/TPSA can help in differentiating malignant from benign changes in prostate in PSA values to 10 ng/ml but not with absolute safety since significant number of patients with proven cancer had these parameters in level range characteristic for benign diseases.

Anatrophic nephrolithotomy (ANL) in the selected cases represents the method of choice in the treatment of staghorn calculi. We evaluated postoperative outcome of patients subjected to standard ANL that received 10 mg of Verapamil immediately before declamping renal artery, due to prevention of reperfusion injury. From 2002 to 2005, 18 nephrolithotomies were performed on 15 patients, in the Urology Clinic, University of Sarajevo Clinics Centre. Preoperative evaluation included intravenous urography and radionuclide renal scans which had been repeated 6 months after the operations. 10 males and 5 females were operated with mean age of 45 years. Urography and renal scans showed severe calyceal distortion and infundibular stenosis in 83% cases, complicated with ureteropelvic junction obstruction in 55% cases. Chronic kidney failure was present in 60% patients. Mean operative time was 150 minutes, with mean cold ischemia time of 61 minutes and mean blood loss of 300ml. There were five minor postoperative complications. Residual small calculi were found in 3 patients. Kidney function was stabilized in the patients suffering from chronic kidney failure, which was proved by radio nuclide imaging. ANL improved by using calcium channel blockers as a protective factor for reperfusion injury proved to be a good treatment choice with a low level of complications and noticeable stabilization and improvement of kidneys function.

Chronic nonbacterial prostatitis/chronic pelvic pain syndrome is unsatisfactorily defined and insufficiently studied illness. Also, the treatment success is questionable and therefore, this illness is a therapeutical problem for urologists--which medications are the best choice in treating this uncomfortable condition? This paper presents results of prospective, open, analytical, comparative study that was performed on 90 patients with diagnosed chronic nonbacterial prostatitis/chronic pelvic pain syndrome. Patients were divided into three groups and were treated with two medications ciprofloxacin (C), doxazosin (D) and combination of ciprofloxacin + doxazosin (C+D). The effects were measured using symptom questionnaire for prostate illnesses of the National Institute for Health - USA (NIH-CPSI). During the basic evaluation, sum ranging from 0 to 43 was calculated for each patient. This number is called total sum NIH-CPSI (National Institutes of Health Chronic Prostatitis Symptom Index) of the questionnaire, which generates the questions from 1 to 9. The most significant change occurred in C+D group where the total sum changed from 18-38 in the beginning to 5-31 at the end of the treatment (55,1% (p<0,001)). Significant changes were also found in D group where the change was 46, 4% (p<0,001). At the end of the treatment no significant change was registered in C group (p<0,005): p<0,001--significance threshold. Combination of ciprofloxacin + doxazosin proved to be the best choice for treatment.

Paper goal is to determine complications after urgent surgical treatment of patient with penile fractures, by using circumferential-degloving technique (degloving penile skin to root of penis). In period between 1998-2006 year, 23 patients have been treated as urgent cases with clinically proven penis fracture, age between 18 and 35. Patients were treated in 3 medical centers in Bosnia and Herzegovina(Sarajevo, Tuzla and Zenica). All 23 (100%) patients were injured during sexual intercourse. In the case of 20 (86,9%) patients partial rupture of corpus cavernosum was verified. Two (8,6%) patients had a complete rupture of urethra and it was primary sutured. In 22 cases (95,6%) spontaneous erection appeared, and in the case of 2 (8,6%) patients penile curvature was verified. Urgent surgical treatment is the best therapy choice, which enables preservation of erection in great number of cases in patients with penile fracture.
