The fate of clinically insignificant residual fragments following retrograde intrarenal surgery and factors affecting spontaneous passage.

The remaining stone fragments after retrograde intrarenal surgery (RIRS) can lead to stone recurrence/regrowth, or stone-related events (SRE). We aimed to delineate the clinical circumstances that are decisive for spontaneous passage of clinical insignificant residual fragments (CIRF) (primary outcome) and define risk factors for stone recurrence/regrowth and their clinical manifestation (secondary outcome). A total of 115 patients who had CIRF following RIRS were included in this study. Demographic, clinical data, stone, and anatomic characteristics including infundibulopelvic angle (IPA), infundibular length (IL) and follow-up data of patients were analyzed. The mean follow-up time was 27.5 ± 6.9 months. 31 (26.9%) patients passed the CIRF spontaneously. Patients were divided into two groups as spontaneous fragment passage group and fragment remaining group and compared with respect to demographic, clinical, stone-related, and anatomic characteristics. 61.2% of patients had lower pole CIRF in fragment remaining group and 83.3% of patients in spontaneous fragment passage group (p = 0.031). In addition, IPA was wider in spontaneous fragment passage group (60.7° vs 51.4°, p = 0.001). A subanalysis was performed for fragment remaining group. In 84 patients, 44 (52.4%) patients were stable for their CIRF at their follow-up and included in stable group. 40 (47.6%) patients experienced stone re-growth (27 patients) or SRE (13 patients) at their follow up. Patients in re-growth/SRE group were older (49.1 vs 39.4 years, p = 0.047), had higher body mass index (28.2 vs 27 kg/m2, p = 0.03) and larger CIRF (2.8 vs 2.1 mm). CIRFs may be not expelled spontaneously and they may lead to additional morbidity and lithotripsy interventions.

The Value of Prostate-Specific Antigen Density in Combination with Lesion Diameter for the Accuracy of Prostate Cancer Prediction in Prostate Imaging-Reporting and Data System 3 Prostate Lesions.

INTRODUCTION: The aim of the study was to investigate the value of prostate-specific antigen density (PSAD) and lesion diameter (LD) combination in prostate cancer (PCa) detection. METHODS: 181 patients who were detected to have prostate imaging-reporting and data system (PI-RADS) 3 lesions in mpMRI and underwent prostate biopsies were included in the study. Demographic, clinical, and pathological data of all patients were evaluated. The patients were divided into four groups according to PSAD and LD status (PSAD <0.15 ng/mL/cc + LD <1 cm, PSAD <0.15 ng/mL/cc + LD ≥1 cm, PSAD ≥0.15 ng/mL/cc + LD <1 cm, and PSAD ≥0.15 ng/mL/cc + LD ≥1 cm). Diagnostic ability for PCa and clinical significant PCa (csPCa) was evaluated by PSAD and LD. RESULTS: PSAD ≥0.15 ng/mL/cc (OR = 6; 95% Cl = 2.847-12.647; p < 0.001), LD ≥1 cm (OR = 7.341; 95% confidence interval [CI] = 2.91-18.52; p < 0.001), and combination of PSAD ≥0.15 ng/mL/cc and LD ≥1 cm (OR = 10.023; 95% CI = 4.32-23.252; p < 0.001) were associated with PCa detection rates. The most sensitivity, specificity, negative, and positive predictive values were found in PSAD ≥0.15 ng/mL/cc + LD ≥1 cm group for both PCa and csPCa detection (48.8%, 92%, 85.2%, and 65.6% for any PCa detection; 66.7%, 85.2%, 97.3%, and 24.2% for csPCa detection, respectively). CONCLUSION: The presence of PSAD ≥0.15 ng/mL/cc or LD ≥1 cm in mpMRI of patients with PI-RADS 3 lesions is associated significantly with the finding of PCa and particularly with the detection of csPCa.

YouTube™ as a source of information on prostatitis: a quality and reliability analysis.

It was aimed to analyze the YouTube™ videos on prostatitis regarding their source, content, and information included. The term "prostatitis" was searched by relevance and the first 200 video links and features were recorded. Using the 5-point modified DISCERN tool, Global Quality Score (GQS), and Journal of American Medical Association (JAMA) score, the quality and reliability of the information were assessed by two urologists. Inter-rater agreement for DISCERN, JAMA, and GQS had Cohen's kappa coefficients of 0.883, 0.887, and 0.885, respectively. The most common source of upload was doctors/medical institutions (33.0%), and the majority of the content was about general information (27.0%). The mean modified DISCERN, GQS and JAMA scores were 3.24 ± 1.23 (1.00-5.00), 3.25 ± 1.26 (1.00-5.00) and 2.17 ± 1.36 (0.00-4.00), respectively. These scores were correlated with each other (r = 0.914, p < 0.001 between JAMA and GQS; r = 0.954, p < 0.001 between JAMA and modified DISCERN; and r = 0.885, p < 0.001 between GQS and modified DISCERN, Spearman test) and were the highest in the videos uploaded by doctors/medical institutions (p < 0.001, Kruskal-Wallis test). Of the videos, 25.5% were poor, 30.5% were moderate and 44.0% were high quality. The high quality videos were significantly shorter than those with poor quality (p = 0.039, Kruskal-Wallis test). The poor quality videos had the highest view ratio (50.49 ± 127.74 (0.03-618.91), p = 0.036, Kruskal-Wallis test). Most YouTube™ videos on prostatitis are short and high quality videos uploaded by doctors/medical institutions. However, these videos have less view ratios than those with poor quality.

Does surgical position affect infective complications in percutaneous nephrolithotomy?

The downward orientation of the access sheath during supine percutaneous nephrolithotomy (PCNL) allows the faster evacuation of fluids and stone fragments. It theoretically can contribute to the reduction of the high intrarenal pressure-associated complications. We aimed to investigate whether there is a difference between prone and supine PCNL in terms of infective complications. This retrospective study includes 182 patients who underwent supine and prone PCNL due to kidney stones in our clinic between April 2020 and May 2022. Demographic (age, sex, body mass index, comorbidities), radiological (cumulative stone burden, stone density, number of stones, stone localization, stone laterality, presence of hydronephrosis), clinical (previous stone surgery, previous urinary tract) and perioperative (prone or supine position, surgery duration, hospitalization, success, non-infective and infective complications) data of all patients were evaluated. All patients were divided into two groups, the prone position group, and the supine position group. These two groups were compared in terms of pre and postoperative data above. Infective complications were observed in 16 (18%) patients in the prone position group and in 7 (7.5%) patients in the supine position group, and this difference was statistically significant (p = 0.034). Surgery duration (OR = 1.041; 95% CI 1.021-1.061; p < 0.001), number of stones (OR = 4.09; 95% CI 1.093-7.309; p = 0.036), previous urinary tract infection (OR = 6.272; 95% CI 1.936-9.317; p = 0.002) and prone position (OR = 4.511; 95% CI 1.265-7.087; p = 0.02) were found as independent risk factors for infective complications. Prone position was proved as an independent predictor of postoperative infectious events. Supine PCNL will be further adopted as the standard PCNL approach by a continuously growing proportion of endourologists.

External validation of the T.O.HO. score as predictor of success after retrograde intrarenal surgery.

BACKGROUND: To assess the effectiveness of T.O.HO. (Tallness, Occupied lesion, Houndsfield unit evaluation) score in predicting the retrograde intrarenal surgery (RIRS) success and to validate this scoring system. METHODS: The age, sex, previous stone surgery, hospitalization, surgery duration, postoperative complication, stone length, stone location, stone density, stone number, lateralization, presence of hydronephrosis, and presence of preoperative stent datas of 611 patients who underwent RIRS in our clinic between January 2013 and January 2021 were retrospectively assessed. The patients were divided into two groups as successful and unsuccessful. The T.O.HO scores of all patients were calculated. RESULTS: The success rate was 72.5%. Compared to the unsuccessful group, stone length and stone density were lower, surgery duration was shorter and there were less lower pole stones in the successful group (p < 0.001). No significant difference was found between the two groups in terms of the other parameters. The T.O.HO. score was significantly lower in the successful group compared to the unsuccessful group (p < 0.001). According to the multivariate logistic regression analysis, stone length (OR: 0.905; 95% Cl: 0.866-0.946; p < 0.001), lower pole location (OR: 0.546; 95% Cl: 0.013-0.296; p < 0.001), stone density (OR: 0.999; 95% Cl: 0.998-1; p = 0.044) and the T.O.HO. score (OR: 0.684; 95%Cl: 0.554-0.844; p < 0.001) were found as the independent risk factors for RIRS success. ROC curve analysis showed that the T.O.HO. score could predict the RIRS success with 7.5 cut-off point (AUC: 0.799, CI: 0.76-0.839; p < 0.001). CONCLUSION: The T.O.HO. score can predict RIRS success with a high rate of accuracy.

Can the Stone Scoring Systems Be Used to Predict Infective Complications of Retrograde Intrarenal Surgery?

OBJECTIVE: We aimed to evaluate whether the retrograde intrarenal surgery (RIRS) scoring systems (Resorlu-Unsal Stone Score [RUSS], modified Seoul National University Renal Stone Complexity Score [modified S-ReCS], and R.I.R.S. score) can predict the infective complications after RIRS. SUBJECT AND METHODS: A total of 581 patients who underwent RIRS for kidney stones were included in the study. All patients were evaluated for demographic data, medical history, radiological imaging methods before surgery, duration of surgery, and hospitalization time after surgery. Stone laterality, stone burden, stone size, stone density, the number of stones, stone localization, the presence of congenital kidney anomaly, and solitary kidney were evaluated preoperatively by computed tomography. The RUSS and modified S-ReCS and R.I.R.S. score of all patients were determined. RESULTS: Infective complications were detected in 47 (8.1%) patients who underwent RIRS. Fever developed in 27 subjects (4.6%), urinary infection in 15 (2.5%), sepsis in 2 (0.3%), and septic shock in 3 (0.5%) patients. In multivariate logistic regression analysis, age (OR = 1.8; 95% CI = 1-3.4; p = 0.049), surgical duration of >60 min (OR = 1.9; 95% CI = 1.1-3.5; p = 0.027), and high R.I.R.S score (OR = 8.9; 95% CI = 1.9-42.4; p = 0.006) were shown to be independent risk factors for the infective complications after RIRS. A receiver operating characteristic curve analysis showed that the R.I.R.S. score can be used as a marker to predict infective complications (AUC = 0.619, CI = 0.55-0.69; p = 0.007). CONCLUSION: We suggest that the R.I.R.S. score can be used to predict infective complications in RIRS.

Evaluation of factors associated with the detection of incidental prostate cancer after open prostatectomy for benign prostatic hyperplasia.

We aimed to evaluate the incidental prostate cancer (PCa) rate and predictive factors in patients who underwent open prostatectomy (OP) with a pre-diagnosis of benign prostatic hyperplasia (BPH). This study included patients with a pre-diagnosis of BPH, who underwent OP due to symptomatic prostate enlargement. Our database included age, medications, prostate-specific antigen (PSA), free/total PSA ratio, PSA density, digital rectal examination (DRE), prostate volume, serum neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, aspartate aminotransferase/alanine aminotransferase ratio, presence of metabolic syndrome (MetS) and histopathological results after OP. Of the 430 patients that underwent OP, 406 (94.4%) with a benign pathological diagnosis were evaluated as the benign group and 24 (5.6%) detected to have PCa constituted the incidental PCa group. The rate of incidental PCa was much higher in the elderly patients. The cut-off value of age was 71.5 years in the PCa group according to the receiver operating characteristic curve analysis. According to the multivariate analysis, DRE and the presence of MetS were effective in predicting PCa (p < .001 and p = .031, respectively). DRE was found 16 times more effective and MetS was 2.8 times more effective than the other parameters. Our results showed that DRE and the presence of MetS could be useful predictive factors of incidental PCa in OP.

Evaluation of the anatomical factors affecting the success of retrograde intrarenal surgery for isolated lower pole kidney stones.

Studies which examine the factors affecting success rate in kidney stones located in the lower pole as well as the effects of infundibulopelvic angle (IPA) and infundibular length (IL) have been conducted with a small number of patients. We aimed to evaluate the cut-off points of IPA and IL parameters that effect the success of retrograde intrarenal surgery (RIRS) for isolated lower pole kidney stones. This retrospective study includes 168 patients who underwent primary RIRS due to isolated lower pole kidney stones in our clinic between January 2013 and May 2020. Pre-operative demographic data, medical history, physical examination, surgery duration as well as the post-operative hospitalization time of patients specifics were obtained. According to pre-operative computed tomography (CT), stone size, stone burden, stone density, number of stones (single and multiple), stone laterality, congenital kidney abnormality, the presence of solitary kidney, parameters of IPA and IL were measured and both included in the study. All patients were divided into two groups as the successful group and the unsuccessful group according to their post-operative success. These two groups were compared in terms of pre and post-operative data. Stone burden, IPA < 42.65°, and IL > 27.5 mm were specified as the independent risk factors for success of RIRS procedure. The patients for whom RIRS procedure is planned for lower pole kidney stones, stone burden, IPA, and IL should be taken into consideration to be able to predict success and it should be kept in mind that additional treatment may be required.

Comparison of percutaneous nephrolithotomy and retrograde intrarenal surgery outcomes for kidney stones larger than 2 cm from Guy's stone scoring system perspective.

OBJECTIVE: To compare surgical outcomes of percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgeries (RIRS) as a result of kidney stones larger than 2 cm, together with Guy's stone scores (GSS). MATERIALS AND METHODS: The data of 811 patients with stone sizes 2-6 cm were operated using PNL (n = 361) and RIRS (n = 450) reviewed retrospectively. GSS were graded 1, 2, 3 or 4 according to the computed tomography findings. Stone-free rate (SFR), operation times, length of hospital stay (LOHS) and Clavien complications (CC) were recorded. RESULTS: Although mean operative times were significantly longer in the RIRS group than the PNL group in GSS grades 1, 2 and 3 (P < .001), it was similar between the two groups in GSS grade 4 (P = .186). SFRs in the PNL and RIRS group were 90.3% and 58.4% on post-operative 10th day (P < .001), and it raised up to 95.3% and 81.6% after secondary interventions (P < .001). Significantly higher SFRs observed in the PNL group in GSS grades 1, 2 and 3 categories. On postoperative 10th day, the SFRs were similar in both GSS grade 4 categories (P = .06). LOHS was longer in the PNL group (P < .001). Although LOHS was significantly longer only in GSS grade 3 (P = .043) and GSS grade 4 (P < .001) in the PNL group, it was similar in GSS grade 1 and 2 between groups. Clavien complications increased in line with GSS in the PNL group (P < .001), but the difference did not differ between GSS grade 3 and 4. CONCLUSION: SF of PNL in a single session and short operation time seems to be significant especially in GSS grades 1, 2 and 3 category stones. Although the number of patients in the GSS 4 group is very small to claim this, RIRS might be considered as an alternative to PNL in a special group of patients such as GSS grade 4 because of its lower complication rates and shorter LOHS.

Analysis of clinical factors associated with intraoperative and postoperative complications of retrograde intrarenal surgery.

The aim of this study was to evaluate the factors affecting intraoperative and postoperative complications in retrograde intrarenal surgery. In this retrospective cohort study, 706 retrograde intrarenal surgery procedures administered to 617 patients were reviewed. Intraoperative and postoperative complications were classified according to the modified Satava and modified Clavien classification systems. The stone-free rate was 407 (57.6%) and the success rate was 528 (74.8%). Intraoperative complications were observed in 215 (30.5%) patients. The most common intraoperative complication was mild bleeding 60(8.5%), while the only independent risk factor associated with intraoperative complications was the presence of residual stones. Postoperative complications were observed in 190 (26.9%) patients. The most common postoperative complication was fever requiring antipyretic drugs 60(8.6%), while independent risk factors associated with postoperative complications were the presence of residual stones and solitary kidney.

Evaluating the anxiety and depression status of prostate cancer patients whose operations were postponed because of the COVID-19 pandemic.

AIM: In this study, we aimed to evaluate the anxiety and depression status of prostate cancer (PCa) patients whose planned operations in the urology clinic of our hospital, which is serving as a pandemic hospital in Turkey have been postponed because of the coronavirus disease 2019 pandemic. METHODS: This survey study was conducted at urology clinic of Ankara City Hospital between March 1 and June 1, 2020, and included 24 male patients who agreed to answer the questionnaires (State-Trait Anxiety Inventory [STAI] I and II and Beck Depression Inventory [BDI]). Demographical and clinical data (age, time since diagnosis, total serum prostate-specific antigen (PSA) levels, risk groups according to the D'Amico classification system, smoking, alcohol habitus, major surgical history and comorbidities) of the patients were collected from hospital software. RESULTS: The mean STAI-I score of the patients (46.7 ± 1.4 [44-49]) was significantly higher than their STAI-II score (41.7 ± 2.4 [39-47]) (P < .001). The negative correlation between the decrease in age and STAI-I score was found to be statistically significant (r = 0.439, P < .05). The mean BDI score of the patients was 4.3 ± 3.2 (0-13), which was compatible with mild depression. There was no statistically significant difference among the time elapsed from diagnosis, PSA levels, smoking and alcohol habitus, major surgical history and comorbidity status and STAI-I, STAI-II and BDI scores (P > .05). CONCLUSION: Prostate cancer patients with postponed operations should be guided properly in order to manage their anxiety status especially young patients.

The Effects of Transobturator Tape Surgery on Sexual Functions in Women With Stress Urinary Incontinence.

INTRODUCTION: Stress urinary incontinence (SUI) can adversely affect the patient's sexual function. AIM: To evaluate the sexual functions in women who underwent transobturator tape (TOT) surgery because of stress urinary incontinence and factors affecting the treatment results. METHODS: The study was conducted in 2 tertiary level clinics between 2013 and 2019 and included sexually active patients with a diagnosis of SUI who underwent TOT operation. The preoperative and postoperative (6 months after surgery) Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire short form (PISQ-12) scores of the patients were evaluated. The patients were evaluated according to the score changes of an increased score (benefited) and the same or lower score (did not benefit). The PISQ-12 questionnaire has 3 subdomains of behavioral-emotive (Q: 1-4), physical (Q: 5-9), and partner-related (Q: 10-12). Each question is scored from 0 to 4, giving a total ranging from 0 to 48. A higher PISQ-12 score indicates better sexual function. MAIN OUTCOME MEASURE: PISQ-12. RESULTS: The study included 117 patients with a median age of 52 years (range, 32-67 years), and 51.3% of the patients were postmenopausal. When the preoperative and postoperative PISQ-12 scores were evaluated in the whole group, there was a statistically significant improvement (from 24.66 to 26.52, P = .001). In the analysis of domains, there was a statistically significant improvement in physical score (from 11.68 to 13.53, P < .001), whereas behavioral-emotive and partner-related scores did not significantly change. In the multivariate analysis of menopausal status, parity and presence of diabetes mellitus were all independently and significantly associated with poor PISQ-12 outcome (OR: 2.60, 95% CI: 1.41-4.81, P = .002; OR: 1.59, 95% CI: 1.03-2.47, P = .034; and OR: 2.42, 95% CI: 1.28-4.58, P = .007, respectively). CONCLUSION: Both physical and psychological statuses should be taken into consideration when planning treatment in patients with urinary incontinence, and it should be noted that postsurgical sexual function status may not be positively affected in postmenopausal, multiparous, and diabetic patients.

Comparison of the Efficacy of Local Anesthesia Methods and Caudal Regional Anesthesia in Prostate Biopsy Applied Under Transrectal Ultrasonography: A Randomized Controlled Study.

PURPOSE: To evaluate the efficacy of caudal regional anesthesia and local anesthesia methods in prostate biopsy applied under transrectal ultrasonography. Matherials and Methods: This prospective study included a total of 160 patients randomly separated into 4 equal groups as intrarectal local anesthesia (IRLA), periprostatic local anesthesia (PPLA), combined local anesthesia (IRLA+PPLA), and caudal regional anesthesia (CRA). The patients were evaluated using the pain scores on a visual analog scale. RESULTS: The pain score during anesthesia induction was significantly higher in the CRA group than in the IRLA and IRLA+PPLA groups (p<0.001). The pain score during entry of the probe to the rectum and movement was significantly lower in the CRA group than the IRLA groups (p=0.014). The pain score on penetration of the needle to the prostate and at 30 mins after the biopsy was significantly higher in the IRLA group (p<0.001). At 2 hours after the biopsy, the pain score in the CRA group was significantly lower than IRLA groups (p=0.015). CONCLUSION: The PPLA alone can be applied more quickly than CRA, causes less pain during the application, and has similar efficacy in reducing pain during and after the prostate biopsy procedure.

Effect of age on biochemical recurrence after radical prostatectomy.

The aim of the study was to evaluate the relationship between patient's age and biochemical recurrence (BCR) after radical retropubic prostatectomy (RRP). Data from RRP applied to 305 patients with clinically localized prostate cancer were included in the study. Patients were divided into the three age groups, < 60 years, 60-70 years, and > 70 years. The groups were compared regarding adverse pathological findings on RRP specimen, BCR, and biochemical recurrence-free survival (bRFS) rates. The rates of positive surgical margin, seminal vesicle invasion, lymph node involvement, RRP specimens' Gleason score, and BCR were not significantly different among the three age groups. bRFS rates were not different either. Nonorgan-confined disease and extracapsular extension (ECE) rates were significantly higher in the group of 60-70 years group than in the other two age groups. Factors associated with BCR in multivariate Cox regression analysis were ECE, seminal vesicle invasion, positive surgical margin, and RRP specimens' Gleason score of ≥ 4+3. Patient age and preoperative prostate specific antigen levels were not identified to be associated with BCR. Post-RRP nonorgan-confined disease and ECE are more frequently seen in patients of 60-70 years of age group than in other age groups. However, patient age is not an independent prognostic factor associated with bRFS.

Flurbiprofen alone and in combination with alfuzosin for the management of lower urinary tract symptoms.

INTRODUCTION: We aimed to investigate the effectiveness and safety of flurbiprofen, a non-steroidal anti-inflammatory drug with dual cyclooxygenase inhibition, and α-blocker alfuzosin, both alone and in combination with each other for lower urinary tract symptoms suggestive of benign prostatic obstruction (LUTS/BPO). MATERIAL AND METHODS: Ninety patients complaining of moderate-to-severe LUTS/BPO were randomly assigned into 3 groups (30 patients each) to receive alfuzosin XL 10 mg, or flurbiprofen SR 200 mg, or combination of alfuzosin XL 10 mg and flurbiprofen SR 200 mg, once daily for 4 weeks. Patients were evaluated using the international prostate symptom score (IPSS) (total and IPSSstorage, IPSSempty subscores), uroflow-metry (maximum (Qmax) and average (Qave) flow rates) and postvoid residual urine (PVR) both at baseline and following the drug therapy course. RESULTS: There was no difference among the 3 groups regarding age and baseline values of prostate volume, IPSS, IPSSstorage, IPSSempty, Qmax, Qave and PVR (P >0.05). IPSS, IPSSstorage, IPSSempty, and PVR decreased significantly in all the 3 groups after drug therapies (P <0.01). However, Qmax and Qave significantly improved only in the combination group (P <0.01). CONCLUSIONS: Addition of flurbiprofen increased the therapeutic effectiveness of alfuzosin by further improving symptoms in patients with LUTS/BPO. Combination therapy also improved urine flow compared to baseline. Monotherapy with flurbiprofen was not superior to alfuzosin.

Evaluation of biochemical recurrence-free survival after radical prostatectomy by cancer of the prostate risk assessment post-surgical (CAPRA-S) score.

BACKGROUND: The cancer of the prostate risk assessment (CAPRA) score has been defined to predict prostate cancer recurrence based on the pre-clinical data, then pathological data have also been incorporated. Thus, CAPRA post-surgical (CAPRA-S) score has been developed based on six criteria (prostate specific antigen (PSA) at diagnosis, pathological Gleason score, and information on surgical margin, seminal vesicle invasion, extracapsular extension and lymph node involvement) for the prediction of post-surgical recurrences. In the present study, biochemical recurrence (BCR)-free probabilities after open retropubic radical prostatectomy (RP) were evaluated by the CAPRA-S scoring system and its three-risk level model. MATERIALS AND METHODS: CAPRA-S scores (0-12) of our 240 radical prostatectomies performed between January 2000-May 2011 were calculated. Patients were distributed into CAPRA-S score groups and also into three-risk groups as low, intermediate and high. BCR-free probabilities were assessed and compared using Kaplan-Meier analysis and Cox proportional hazards regression. Ability of CAPRA-S in BCR detection was evaluated by concordance index (c-index). RESULTS: BCR was present in 41 of total 240 patients (17.1%) and the mean follow-up time was 51.7±33.0 months. Mean BCR-free survival time was 98.3 months (95% CI: 92.3-104.2). Of the patients in low, intermediate and high risk groups, 5.4%, 22.0% and 58.8% had BCR, respectively and the difference among the three groups was significant (P=0.0001). C-indices of CAPRA-S score and three-risk groups for detecting BCR-free probabilities in 5-yr were 0.87 and 0.81, respectively. CONCLUSIONS: Both CAPRA-S score and its three-risk level model well predicted BCR after RP with high c-index levels in our center. Therefore, it is a clinically reliable post-operative risk stratifier and disease recurrence predictor for prostate cancer.

Association between prostatic resistive index and cardiovascular risk factors in patients with benign prostatic hyperplasia.

We evaluated the relationship between prostatic resistive index (RI) and cardiovascular system (CVS) risk factors in patients with benign prostatic hyperplasia. The study included 120 patients who were attending our outpatient clinic with lower urinary tract symptoms related to benign prostatic hyperplasia. The clinical, laboratory, anthropometric data, and CVS risk factors (hypertension, diabetes mellitus, metabolic syndrome, history of CVS events, and smoking) of the patients were evaluated regarding the association between prostate RI level by regression analyses. The prostatic RI levels of the patients were measured using power Doppler imaging. In univariate regression analysis, there were statistically significant relationships between prostatic RI levels and the patients' age, International Prostate Symptom Score, hip circumference, fasting blood glucose, prostate specific antigen, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, total prostate volume, uroflowmetric maximal flow rate, and all investigated CVS risk factors (p < 0.05). The prostatic RI levels were found to be associated with fasting blood glucose and total prostate volume, and also with CVS risk factors including only metabolic syndrome and cigarette smoking in the multivariate regression analysis. Our results showed that prostatic RI level is significantly related to metabolic syndrome and smoking among the investigated CVS risk factors.

Effects of medical therapy or surgery on prostatic and bladder resistive indices in patients with benign prostatic hyperplasia.

INTRODUCTION: The effects of medical therapy or surgery on bladder and prostatic resistive indices (RIs) in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) were evaluated in the present study. PATIENTS AND METHODS: A total of 124 consecutive LUTS/BPH patients who were candidates for medical therapy (alfuzosin 10 mg once daily, n=66) or surgery (transurethral prostatectomy (TUR-P), n=58) were prospectively included. Baseline assessment of patients was performed with the International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax), and prostatic and bladder RIs measured using power Doppler imaging (PDI). All patients were re-evaluated 3 months after treatment measuring the same parameters. RESULTS: Following medical therapy, mean IPSS (17.2±5.1 vs. 8.3±5.3, p=0.0001), postvoiding residual (PVR) urine (80.0±80.5 vs. 40.3±38.6, p=0.0001), and prostatic RI (0.73±0.1 vs. 0.70±0.1, p=0.0001) were decreased, Qmax (13.7±4.2 vs. 16.9±5.9, p=0.0001) was increased, and bladder RI remained unchanged (0.70±0.1 vs. 0.70±0.1, p=0.68). Mean IPSS (25.3±5.6 vs. 6.0±4.5, p=0.0001), PVR urine volume (134.5±115.5 vs. 35.7±25.9, p=0.0001), and prostatic (0.78±0.1 vs. 0.67±0.04, p=0.0001) and bladder RIs (0.72±0.1 vs. 0.64±0.04, p=0.005) were decreased, and Qmax (8.0±4.5 vs. 17.2±8.2, p=0.0001) was increased after TUR-P. CONCLUSIONS: Our results demonstrated that TUR-P decreased both prostatic and bladder RIs, while α-blocker therapy did not change bladder RI in the early posttreatment period in LUTS/BPH patients.

Metabolic syndrome prevalence in renal cell cancer patients.

PURPOSE: Renal cell carcinoma (RCC) is increasingly being recognized as a metabolic disease in recent studies. The aim of the present study was to identify the prevalence of metabolic syndrome (MetS) and its association with RCC among urologic patients. MATERIALS AND METHODS: The study included a total of 355 participants (117 adult RCC patients and 238 age matched controls) divided into groups, with and without MetS diagnosed using the criteria of the American Heart Association/The National Heart Lung and Blood Institute. Groups were compared statistically and logistic regression analysis was performed to investigate the impact of MetS criteria on RCC risk. RESULTS: Of the 117 RCC patients, 52 (44.4%) and of the 238 controls, 37 (15.5%) had MetS. A significant association (p<0.001) was found between the presence of MetS and RCC (OR: 4.35; 95% CI=2.62- 7.21). As the number of MetS components accumulated from 3 to 5, RCC risk increased likewise from 4 to 6 times. CONCLUSIONS: MetS is more prevalent in RCC patients in Turkey compared to controls. Risk increases with the number of coexisting MetS components.

Association of prostate volume with voiding impairment and deterioration in quality of life after prostate biopsy.

OBJECTIVE: To evaluate how voiding function and quality of life (QoL) were affected by transrectal ultrasound-guided prostate biopsy with respect to prostatic size and to determine whether there is a size-bothersomeness relationship. METHODS: Ninety-two patients who were candidates for prostate biopsy were included. Ten-core prostate biopsies were taken, and patients were followed up for 7 days. The international prostate symptom score, QoL, maximum urine flow rate (Q-max) and average urine flow rate, postvoid residual urine, and prostate volume (Vp) of the patients were recorded at baseline and on postbiopsy day 7. On receiver operating characteristics curve analysis, a Vp of 38.8 mL was found to be the best cutoff point for deterioration in QoL after biopsy. Then, patients were divided into 2 groups according to baseline Vp, as <38.8 mL and ≥38.8 mL, group 1 and 2, respectively. Baseline and postbiopsy values were compared. RESULTS: One patient in group 1 and 5 in group 2 developed acute urinary retention after biopsy, but the difference was not significant (P >.05). Only Vp and Q-max of group 1 (P <.001 and P = .035, respectively), but QoL (P = .002), international prostate symptom score, Q-max, Vp (P <.001 in all 3), and average urine flow rate (P = .006) of group 2 were significantly changed on postbiopsy day 7 compared with baseline. CONCLUSION: Patients with a Vp >38.8 mL were more prone to voiding difficulty and deterioration in QoL after biopsy. They should be informed about the likelihood of these complications.
