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.

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.

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.

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.

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.

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.

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.

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.

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.

Efficiency of the estimation of physiologic ability and surgical stress (E-PASS) score in predicting postoperative complications after robot-assisted radical prostatectomy.

BACKGROUND: Robot-Assisted Radical Prostatectomy (RARP) is increasingly becoming the standard surgical treatment for prostate cancer. While some risk factors for postoperative complications of RARP have been identified, no scoring model that incorporates both preoperative physical status of the patient and intraoperative risk factors has been developed. The Estimation of Physiologic Ability and Surgical Stress (E-PASS) score was initially described to predict postoperative complications after gastrointestinal surgical procedures. This study aims to assess the effectiveness of the E-PASS score in predicting postoperative complications of RARP. METHODS: A retrospective evaluation was conducted on 204 patients who underwent RARP between 2019 and 2022. Demographic data, parameters indicating patients' preoperative physical condition, and intraoperative risk factors were analyzed. The E-PASS score and subscores were calculated for each patient. RESULTS: Of the patients, 164 (80.4%) were discharged without any postoperative complications (Group 1), and 40 (19.6%) experienced various degrees of complications (Group 2). Patients in Group 2 had higher rates of previous abdominal surgery, elevated Eastern Cooperative Oncology Group (ECOG) performance scores, longer surgical durations, and higher E-PASS scores. To assess the effectiveness of the Comprehensive Risk Score (CRS) as a predictive factor for postoperative complications, a receiver operating characteristic (ROC) curve was constructed with a 95% confidence interval (CI), and a cut-off value was established. The cut-off value for CRS was determined to be -0.0345 (area under the curve [AUC]=0.783, CI: 0.713-0.853; p<0.001). Patients with a CRS higher than the cut-off value had a 16.4 times higher rate of postoperative complications after RARP (95% CI: 5.58-48.5). CONCLUSION: The E-PASS scoring model successfully predicts postoperative complications in patients undergoing RARP by using preoperative data about the physical status of the patient and surgical risk factors. The E-PASS score and its subscores could be utilized as objective criteria to determine the risk of postoperative complications before and immediately after surgery.

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.

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.

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.

Impact of metabolic syndrome on erectile dysfunction and lower urinary tract symptoms in benign prostatic hyperplasia patients.

INTRODUCTION: The aim of this study was to investigate the relationship among metabolic syndrome (MetS), erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) in patients with benign prostatic hyperplasia (BPH). METHODS: Our study included 106 patients with BPH, 33 (31.1%) of whom had MetS. Blood pressures, waist circumferences, serum levels of fasting blood glucose, high density lipoprotein and triglyceride of patients were recorded. Erectile functions of the patients were evaluated by International Index of Erectile Function (IIEF). Patients were divided into two groups according to IIEF scores, namely 'mild/no ED' and 'moderate/severe ED'. IIEF scores of ED groups were between 17 and 30 and 6-16 in turn. LUTS severities were assessed by International Prostate Symptom Score (IPSS) and classified as mild (IPSS 0-7), moderate (IPSS 8-19) and severe (IPSS 20-35). RESULTS: There was a significant difference between ED groups concerning MetS presence (p=0.032). MetS presence was not found to be associated with the severity of LUTS (p=0.144). There was no correlation between ED groups regarding LUTS severity (p=0.303). CONCLUSION: Results of the present study showed a correlation between MetS presence and ED. In the light of our results, MetS seems to play an important role in the etiopathogenesis of ED in patients with BPH.

Stage-by-stage effects of surgical margin status on biochemical failure after radical prostatectomy in patients with clinically localized prostate cancer.

PURPOSE: To evaluate the effects of pathological stage and surgical margin status on biochemical failure rates after radical prostatectomy (RP). MATERIALS AND METHODS: The records of 205 patients who underwent RP for clinically localized prostate cancer (CaP) were evaluated. Known risk factors for biochemical failure (BF) were analyzed using univariate and multivariate logistic regression analysis. The effects of surgical margin status together with pathological stage on BF were evaluated. p values lower than 0.05 were accepted to be statistically significant. RESULTS: Pathological stage, positive surgical margin (PSM), seminal vesicle invasion, lymph node involvement, biopsy Gleason score and postoperative Gleason score were the factors associated with BF in univariate analysis. Logistic regression analysis revealed that pT3a patients with PSM had a significant BF rate when compared to pT2 patients with a negative surgical margin (NSM) (OR 7.46, p = 0.002). pT3a patients with a NSM had a similar BF rate to that of pT2 patients with PSM. CONCLUSIONS: pT2 patients with PSM had a similar biochemical prognosis to that of pT3a patients without PSM, implicating that a PSM may have a negative effect on prognosis similar to that of extracapsular invasion.

Effect of transurethral resection of prostate on prostatic resistive index.

INTRODUCTION: In the present study, we evaluated the effect of transurethral resection of the prostate (TUR-P) on prostatic resistive index (RI) in patients with benign prostatic hyperplasia(BPH). PATIENTS AND METHODS: Forty BPH patients who were candidates for prostatectomy were prospectively included in the study. Prostatic RI was measured using power Doppler imaging (PDI) before TUR-P. In the postoperative follow-up, all patients were reevaluated with PDI, International Prostate Symptom Score (IPSS) and uroflowmetry. RESULTS: Mean age, IPSS and maximal urine flow rate (Q(max)) of the patients was 65.8 +/- 7.6 years, 24.6 +/- 7.1 and 7.7 +/- 3.8 ml/s, respectively. The mean prostatic RI of the patients before TUR-P was 0.79 +/- 0.02. Prostatic RI positively correlated with total prostate volume and IPSS (r = 0.57, p = 0.0001, and r = 0.42, p = 0.008, respectively) and negatively correlated with Q(max) (r = -0.37, p = 0.029) prior to treatment. After TUR-P, mean IPSS and prostatic RI significantly decreased (6.5 +/- 4.3 and 0.68 +/- 0.03, respectively; p < 0.05), whereas mean Q(max) was increased (15.7 +/- 5.7, p < 0.05). CONCLUSIONS: Our data demonstrated that prostatic RI of the patients with BPH significantly decreased after TUR-P. We believe that prostatic RI could be a useful parameter for the follow-up of patients who underwent TUR-P.

The effects of N-acetylcysteine on testicular damage in experimental testicular ischemia/reperfusion injury.

PURPOSE: The aim of this study to evaluate the effects of N-acetylcysteine (NAC) on testicular damage in a rat testicular ischemia-reperfusion (I/R) injury model. METHODS: Thirty male Wistar albino rats were divided into five groups. Group 1: sham control, Group 2: torsion (T), Group 3: torsion/detorsion (T/D), Group 4: the early NAC treatment plus T/D, 20 mg/kg of NAC was given intravenously 60 min before detorsion; Group 5: the late NAC treatment plus T/D, 20 mg/kg of NAC was given intravenously 5 min before detorsion. After torsion (2 h) and detorsion (2 h), bilateral orchiectomies were performed to determine the tissue levels of malondialdehyde (MDA) or more exactly thiobarbituric acid reactive substance (TBARS), myeloperoxidase activity and histopathological changes. RESULTS: The most significant increase in the mean TBARS level and decrease in the mean seminiferous tubular diameter, germinal epithelial cell thickness values in bilateral testes were observed in T/D group rather than other groups. TBARS levels of early NAC treatment group were significantly lowered and histological parameters of spermatogenesis were significantly improved in bilateral testes when compared with T and T/D groups. CONCLUSION: Our results suggest that the early administration of NAC may have a protective effect in the rat experimental testicular T/D models.

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.

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.

Correlation between upgrading of prostate biopsy and biochemical failure and unfavorable pathology after radical prostatectomy.

OBJECTIVE: To evaluate whether upgrading of the biopsy after radical prostatectomy (RP) affects disease outcome in terms of unfavorable pathology and biochemical failure. PATIENTS AND METHODS: We retrospectively evaluated the records of 174 patients who underwent RP. Prostate biopsy and RP specimen Gleason scores (GSs) and correlative clinical data were recorded, and a multivariate analysis was applied. RESULTS: Overall (138 patients), the disease of 69 men (50.0%) was upgraded, in 19 (13.8%) it was downgraded, and in 50 (36.2%) it had an identical biopsy and pathological GS. Accuracy rates were significantly higher for GS 8-10 compared to low GSs, with a concordance of 50.0 and 12.2%, respectively (p < 0.01). Multivariate analysis revealed the single independent prognostic factor for a non-organ-confined disease as a RP GS 8-10 (p = 0.035). The factors associated with a positive surgical margin were a biopsy GS 8-10 (p < 0.001) and the presence of biopsy score upgrading (p = 0.02). Biopsy GS >or=8 (p < 0.001) and presence of biopsy score upgrading (p = 0.009) were the two independent predictors of relapse after RP. CONCLUSION: This study demonstrated that biopsy upgrading was present in almost half of the patients who underwent RP and it was significantly related to positive surgical margins and biochemical relapse after RP.
