Can systemic immune-inflammation index and hematologic parameters aid in decision-making for active surveillance or curative treatment in low-risk prostate cancer?

INTRODUCTION: Pathologic Gleason Score (GS) upgrading is common in patients with low-risk localized prostate cancer (PCa) who are followed by active surveillance (AS) or undergo radical prostatectomy (RP). This fact raises concerns about inadequate treatment, especially in AS patients. We aimed to analyze the association of preoperative neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and systemic immune-inflammation (SII) index with GS upgrading. MATERIALS AND METHODS: This study was approved by the Ethical Review Committee of Afyonkarahisar Health Sciences University. Data of the patients who underwent RP for PCa at three different centers between 2018 and 2023 were retrospectively analyzed. The patients were divided into 2 groups based on GR upgrading status as "upgrading" and "non-upgrading". Among the patients who underwent RP, 77 patients who fully met the criteria for AS were identified. The patients eligible for AS were divided into "non-upgrading" and "upgrading" groups. These groups were compared regarding NLR, PLR, and SII index values. RESULTS: Overall, data from 250 patients were reviewed. Among these, 147 had GS upgrading, while 103 had no upgrading. Seventy-seven patients were eligible for AS. Among these patients, 30 had upgrading, while 47 were in the "non-upgrading" group. Our analysis revealed that an NLR of 1.85 and above was associated with a 2.238-fold increase in the risk of GS upgrading (p = 0.009). Also, a PLR of 115.7 and above was affiliated with a 2.992-fold increase in the GS upgrading risk (p < 0.001). The analysis regarding patients who underwent RP but were eligible for AS revealed that an NLR of ≥1.68 was associated with a 3.25-fold risk increase in GS upgrading. On the other hand, a PLR≥134.5 and an SII index≥630.7 were affiliated with a 12.303-fold and 6.562-fold increase in the risk of upgrading (p = 0.019, p = 0.018). CONCLUSION: The decision of AS should be carefully reappraised, and treatment methods such as RP or radiotherapy should be considered in patients with high NLR, PLR, or SII index values.

Could twinkling artifact be a parameter in predicting the success of shock wave lithotripsy? A prospective study.

Introduction: It is important to predict success before the treatment of urolithiasis. We aimed to predict the success of shock wave lithotripsy (SWL) by comparing twinkling artifact (TA) revealed through colour Doppler ultrasonography (CDUS) with stone density in non-contrast computed tomography (NCCT). Material and methods: Eighty patients who underwent SWL between January 2021 and January 2022 were included in the study. Patients with stones of 5-20 mm in the renal pelvis and proximal ureter at NCCT were included. Patients' demographics, Hounsfield units (HU) in NCCT, and TA grades in CDUS were recorded. The stone-free rate after SWL, additional treatments, overall success rates, and the association between TA and success rates were evaluated. Results: The mean age was 47.41 ±15.08 years. The mean BMI was 24.49 ±3.67 kg/m2. Twenty-three (28.8%) patients were TA grade 0, 33 (41.2%) patients were grade 1, and 24 (30%) were grade 2. The mean HU of TA grades 0, 1, and 2 of stones were 628 ±107, 864 ±123, and 1166 ±292, respectively. The HU increased along with the increase in the TA grade of the stone (p <0.01). The mean number of SWL sessions was 2.26 ±0.75 in patients with TA grade 0, and 2.92 ±0.40 in patients with TA grade 2. The mean number of SWL sessions increased along with the increase in TA grade (p <0.01). The stone-free rate decreased as the TA grade increased. Stone diameter and TA were the only predictors of SWL success. Conclusions: We think that TA may be useful in predicting SWL success.

Distinct Adverse Clinical Outcomes of Small and Large Cribriform Patterns on Gleason 7 Prostate Cancer: A Preliminary Study.

OBJECTIVE: We aimed to evaluate the effect of large and small cribriform morphology on survival following radical prostatectomy. METHODS: We included 30 patients who underwent radical prostatectomy with curative intent between 2015 and 2022. Patients with the final pathology of Gleason 7 were included. Patients' radical prostatectomy specimens were reviewed by an experienced genitourinary pathologist. The diverse growth patterns of Gleason grade 4 were specified as poorly formed/fused glands, cribriform glands, and glomeruloid glands. The cribriform morphology was subdivided into small and large cribriform. Large cribriform growth morphology was defined by its size, which was double that of benign prostate glands. Small and large cribriform glands' percentages were indicated semiquantitatively. The cribriform morphology subtype present at 50% and higher was defined as the dominant pattern. The effect of histopathological patterns on biochemical recurrence and clinical progression was analyzed. RESULTS: Thirteen patients were small cribriform pattern dominant (group 1), whereas 14 of the patients were large cribriform pattern dominant (group 2). Pathological T, N stages, and surgical margin positivity were similar between groups. Biochemical recurrence and clinical progression rates were significantly higher in group 2. The large cribriform dominant patients had worse 2-year biochemical recurrence-free survival than small cribriform dominant patients (45.5% vs. 66.7%). In the univariate analysis, International Society of Urological Pathology grade, Gleason pattern 4 percentage, large cribriform pattern dominancy, and pT stage were predictors for biochemical recurrence-free survival. International Society of Urological Pathology grade was the only independent predictor for biochemical recurrence-free survival. CONCLUSION: Large cribriform pattern dominancy is associated with worse biochemical recurrence-free survival in Gleason 7 prostate cancer.

Comparison of transcutaneous tibial nerve stimulation versus percutaneous tibial nerve stimulation in category IIIB chronic prostatitis/chronic pelvic pain syndrome: A randomized prospective trial.

BACKGROUND: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a heterogenous condition that impacts the Quality of life severely, and it has multimodal complex treatment options. We aimed to compare the efficacy of two well-described neuromodulation therapies, transcutaneous tibial nerve stimulation (TTNS) versus percutaneous tibial nerve stimulation (PTNS) in the treatment of category IIIB CP/CPPS. METHODS: This study was designed as a randomized prospective clinical trial. We randomized category IIIB CP/CPPS patients into two treatment groups as TTNS and PTNS groups. Category IIIB CP/CPPS was diagnosed by two or four-glass Meares-Stamey test. All patients included in our study were antibiotic/anti-inflammatory resistant. Transcutaneous and percutaneous treatments were applied 30 min sessions for 12 weeks. Patients were evaluated by Turkish-validated National Health Institute Chronic Prostatitis Symptom Index (NIH-CPSI) and visual analogue scale (VAS) initially and after treatment. Treatment success was evaluated within each group and also compared with each other. RESULTS: A total of 38 patients in the TTNS group and 42 patients in the PTNS group were included in the final analysis. The mean VAS scores of the TTNS group were lower than the PTNS group initially (7.11 and 7.43, respectively), (p = 0.03). The pretreatment NIH-CPSI scores were similar between groups (p = 0.07). VAS scores, total NIH-CPSI, NIH-CPSI micturation, NIH-CPSI pain, and NIH-CPSI QoL scores decreased significantly at the end of the treatment in both groups. We found a significantly higher VAS and NIH-CPSI scores decrease in the PTNS group compared to the TTNS group (p < 0.01). CONCLUSION: Both PTNS and TTNS are effective treatment methods in category IIIB CP/CPPS. Comparing the two methods, PTNS provided a higher level of improvement in terms of pain and quality of life.

Impact of COVID-19 on the progression of benign prostatic hyperplasia and aggravation of related symptoms: A prospective study.

OBJECTIVE: This study aims to evaluate the lower urinary tract symptoms (LUTS) of the patients with benign prostatic hyperplasia (BPH) who were admitted due to coronavirus disease (COVID-19) and to show the effect of COVID-19 on BPH. METHODS: This prospective study included patients over the age of 45 admitted due to COVID-19 between June 2021 and December 2021 and treated with alpha-blockers for BPH. During admission, the patients were evaluated by prostate volumes, prostate-specific antigen (PSA) values, and International Prostate Symptom Scores (IPSS). Furthermore, treatment duration due to COVID-19, frequency, nocturia, and voided volumes obtained from the voiding diary was recorded. Finally, the sequent IPSS values were compared by inviting the patients to the urology polyclinic in the first month. RESULTS: The mean age of 142 patients was 72.42 ± 10.21 years. The IPSS scores of the patients increased from 10.66 ± 4.46 to 12.99 ± 3.58 1 month after the diagnosis (p < 0.01). Moreover, the IPSS quality of life (QoL) scores were 2.44 ± 0.58 and 2.75 ± 0.51, respectively (p < 0.01). The mean frequency obtained from the voiding diary data increased from 5.10 ± 1.5 to 5.65 ± 1.36 (p < 0.01), mean nocturia count increased from 1.13 ± 0.05 to 1.39 ± 0.66 per day (p < 0.01), and the mean voiding volume decreased from 320.56 ± 46.76 ml to 298.84 ± 39.74 ml (p < 0.01). CONCLUSION: In this study, we detected an increase in LUTS during COVID-19 treatment. Therefore, it should be noted that symptomatic or asymptomatic COVID-19 patients may refer to urology polyclinics due to aggravation of LUTS.

Efficacy of transcutaneous tibial nerve stimulation in the treatment of bladder pain syndrome.

Background: This study aimed to demonstrate the effectiveness of transcutaneos tibial nerve stimulation (TTNS) in the treatment of bladder pain syndrome (BPS). Materials and methods: The data of 16 female patients, diagnosed with BPS in our clinic between 2019 and 2021 and had TTNS twice a week for 12 weeks, were retrospectively analyzed. Results: The mean age of the patients was 46.00 ±â€Š13.11 years, and the mean body mass index was 26.43 ±â€Š3.07 kg/m2. After the treatment, the median day time frequency of the patients decreased from 13.37 (3.69) to 10.25 (4.56) (p < 0.001). Nocturia also decreased after treatment from 4.37 (1.81) to 3.00 (1.94) (p = 0.001). The median voiding volume increased by 26.5 mL (p = 0.001). The median of the patients' visual analog scale scores decreased after treatment (median of visual analog scale score changed from interquartile range 8 [1] to 7 [4]) (p = 0.001). In addition, the median interquartile range interstitial cystitis symptom index scores decreased from 17 (4) to 15 (10) (p = 0.002). Conclusions: In this study it was demonstrated that TTNS is an alternative method that can be successfully applied before invasive methods in the treatment of BPS.

How effectively do we apply first-line treatment in overactive bladder?

INTRODUCTION AND HYPOTHESIS: We aimed to reveal the effectiveness of the combination of behavioral therapy (BT), drug therapy, and pelvic floor muscle training (PFMT) in patients with the diagnosis of overactive bladder (OAB) who did not respond to drug therapy. METHODS: Seventy female patients aged between 18 and 65 years diagnosed with wet-type OAB, who did not respond to drug therapy, were included in our study, which was planned as a prospective randomized controlled trial. The patients were randomly assigned to one of two groups. BT and a combination of anticholinergic + beta3-agonist was implemented in the control group for 12 weeks. BT and PFMT were applied with a combination of anticholinergic + beta3-agonist in the active therapy group for 12 weeks. Post-treatment changes in OAB, ICIQ-SF scores, and frequency and nocturia were compared. RESULTS: The age and BMI averages of the groups were similar (p>0.01). After the treatment, no significant decrease was observed in OAB scores in the control group (p = 0.06), but a significant decrease was observed in the active therapy group (p<0.01). The mean ICIQ-SF scores and the number of nocturia were found to decrease in both groups after 12 weeks of treatment (p<0.01). There was no significant decrease in frequency in the control group (p = 0.054). It regressed significantly in the active therapy group (p<0.01). After the treatment, 3 of 30 the patients in control group (10%) and 11 of the 32 patients in the active therapy group (34.3%) said that their complaints had regressed and that they were pleased with their current situation. Although after the treatment, 4 patients in the control group were dry (13.3%), 10 patients in the active therapy group were dry (31.25%). CONCLUSIONS: We demonstrated that drug therapy, BT, and PFMT, which are recommended in the first-line treatment of OAB reduce the need for invasive treatments when they are well explained to the patients and combined.

A factor not to be ignored in post-COVID-19 erectile dysfunction; psychological effect, a prospective study.

It was aimed to show the effect of anxiety and depression on erectile dysfunction seen after coronavirus disease-2019 (COVID-19). Between March and July 2021, the participants completed the International Index of Erectile Function, Beck Depression Inventory and Generalised Anxiety Disorder 7 forms at the beginning and after the 1st month of the disease. We investigated the psychological impact of COVID-19 on the development of erectile dysfunction. The mean age of 156 male patients in the study was 54.74 ± 8.01 years. It was determined that the mean International Index of Erectile Function scores of the patients before COVID-19 were 73.42 ± 3.43 and decreased to 68.28 ± 12.86 after COVID-19 (p < .01). The patients' erectile function scores were significantly lower after COVID-19 (29.45 ± 1.23, 27.69 ± 4.33, p < .01, respectively). Their Beck Depression Inventory scores were statistically significantly higher after COVID-19 (1.69 ± 2.56, 2.22 ± 2.79, p < .01, respectively). Their Generalised Anxiety Disorder 7 scores were also statistically significantly higher after COVID-19 (4.69 ± 1.63 6.56 ± 2.40, p < .01, respectively). A negative correlation was found between the increase in the Beck Depression Inventory score during the pandemic process and the decrease in the International Index of Erectile Function score (r = -0.356, p = <.001). A negative correlation was also found between the increase in the Generalised Anxiety Disorder 7 score and the decrease in the International Index of Erectile Function score (r = -0.200, p = .012). One of the main factors post-COVID-19 erectile dysfunction is anxiety and depression due to the disease.

Comparison of the efficiency, safety and pain scores of holmium laser devices working with 20 watt and 30 watt using in retrograde intrarenal surgery: One center prospective study.

OBJECTIVES: Holmium:Yttrium Aluminum Garnet laser lithotripsy is used in Retrograde Intrarenal Surgery. Fragmentation is made with a certain value of pulse energy (Joule) and frequency (Hertz) in Holmium laser lithotripsy and the multiplication of these values gives us total power (Watt). Devices with maximum power of 20 Watt and 30 Watt are used in clinical practice. We want to compare the efficiency, safety and pain scores of the lithotripsy made below 20 Watt and over 30 Watt with 30 Watt laser device. MATERIALS AND METHODS: 60 patients who had 2-3 cm sized kidney stones and operation planned were prospectively divided into three groups. Groups were random identified. In the first group, fragmentation was performed below 20 Watt power with 20 Watt laser device. In the second group, fragmentation was performed below 20 Watt power with 30 Watt laser device. In the third group, fragmentation was performed over 20 Watt power with 30 Watt laser device. Demographic, stone, intraoperative and postoperative data were recorded. We compared these groups regarding efficiency, safety and pain score. RESULTS: For demographic and stone data, there was a statistically significant difference only for stone number. For intraoperative and postoperative data, there was a statistically significant difference only for ureteral access sheath usage between the groups. Success was lower than the other groups in Group 1. CONCLUSIONS: Success was higher in groups using 30 Watt laser device. There was not statistically significantly difference between complications and pain. 30 Watt laser device is safe and efficient in Retrograde Intrarenal Surgery.

Comparison of Retrograde Intrarenal Surgery and Percutaneous Nephrolithotomy Used in the Treatment of 2-4 cm Kidney Stones in Terms of Pain and Need for Additional Analgesics: A Prospective Randomized Study.

Purpose: To compare the effects of retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) on postoperative pain and their differences in terms of the postoperative need for analgesics in the treatment of 2-4 cm kidney stones. Methods: A total of 132 patients who suffered from renal stones 2-4 cm in size and had surgery at our urology clinic between April 2015 and April 2017 were enrolled in this prospective study (NCT02430168). Patients were randomized into either the RIRS group (Group 1) or PNL group (Group 2) in a ratio of 1:1. Postoperative visual analog scale (VAS) values at 8 and 24 hours postoperatively and analgesic treatments of patients were recorded. Results: Patients from both groups had similar demographic characteristics. Stone-free states were achieved in 37 (74%) patients in the RIRS group and 45 (90%) patients in the PNL group. Postoperative complication rates were similar in two groups. Moreover, there was no statistically significant difference between the groups in terms of the postoperative need for analgesics (P = .309). However, the PNL group had higher VAS values (P < .001). Conclusion: Although the early postoperative pain scales were high in the PNL group, there was no significant difference between the groups in terms of the standard analgesic treatments for achieving patient's comfort. PNL, which has similar complications, but with higher success rates, compared with RIRS, did not require additional analgesic treatment during postoperative pain management. Thus, in our opinion, PNL should still remain as a first choice in treatment of 2-4 cm renal stones.

Salvage Ultrasound-guided Targeted Cryoablation of The Perispermatic Cord For Persistent Chronic Scrotal Content Pain After Microsurgical Denervation Of The Spermatic Cord.

OBJECTIVE: To assesses the efficacy of ultrasound-guided targeted cryoablation (UTC) of the perispermatic cord as a salvage treatment for patients who failed microsurgical denervation of the spermatic cord. METHODS: Retrospective review of 279 cases (221 patients: 58 bilateral) undergoing UTC between November 2012 and July 2016, performed by 2 fellowship trained microsurgeons. UTC was performed using a 16-gauge cryo needle (Endocare, HealthTronics, Austin, TX). Branches of the genitofemoral, ilioinguinal, and inferior hypogastric nerves were cryoablated medial and lateral to the spermatic cord at the level of the external inguinal ring. Level of pain was measured preoperatively and postoperatively using the visual analog scale and Pain Index Questionnaire-6 (QualityMetric Inc., Lincoln, RI). RESULTS: Median age was 43 years, operative duration 20 minutes, and postoperative follow-up 36 months (24-60). Subjective visual analog scale outcomes: 75% significant reduction in ain (11% complete resolution and 64% ≥50% reduction in pain). Objective Pain Index Questionnaire-6 outcomes: 53% significant reduction at 1 month (279 cases), 55% at 3 month (279 cases), 60% at 6 month (279 cases), 63% at 1 year (279 cases), 65% at 2 years (275 cases), 64% at 3 years (232 cases), 59% at 4 years (128 cases) and 64% at 5 years (53 cases) post-op. COMPLICATIONS: 2 wound infections, 4 penile pain cases (resolved in a few months). CONCLUSION: UTC of the perispermatic cord is a safe potential treatment option for the salvage management of persistent chronic scrotal pain in patients who have failed microsurgical denervation of the spermatic cord.

Does Previous Failed Shockwave Lithotripsy Treatment Have an Influence on Retrograde Intrarenal Surgery Outcome?

Background: The prevalence of urolithiasis is nearly 20% and patients with urolithiasis constitute an essential part of the patients referred to the urology clinic. Many parameters should be considered for the management of renal stones and authors recommend extracorporeal shockwave lithotripsy (SWL), retrograde intrarenal surgery (RIRS), and percutaneous nephrolithotripsy (PNL), as treatment options. Among these techniques, SWL does not require general anesthesia, has 89% success rate for renal pelvic stones: 83% for upper caliceal stones, 84% for middle caliceal stones, and 68% for lower caliceal stones. In this study, we aimed to investigate whether the previously failed SWL treatment affects RIRS outcome. Methods: Patients who underwent RIRS for kidney stones between January 2012 and December 2017 in Diskapi Yildirim Beyazit Training and Research Hospital were reviewed retrospectively. Patients treated with primary RIRS (186 patients) were classified as Group 1. The outcomes of these patients were compared with those of 186 patients who underwent RIRS after failed SWL treatment using matched-pair analysis, and these patients were classified as Group 2. Results: The procedure success was defined as the sum of the stone-free and clinically insignificant residual fragments (CIRFs); final success rates were 90.3% and 91.9%, respectively. If we compare the final success rates, there was no statistically significant difference between both groups (P = .584). Conclusions: As a result, there is no negative effect of the previous unsuccessful SWL treatment on the RIRS success. Patients with CIRF should be followed up more carefully in terms of becoming symptomatic.

This case report presents a 70-year-old diagnosed with primary prostatic signet ring cell carcinoma, treated with a combination of radiotherapy and hormone therapy and a 16 month survival without an evidence of the disease at follow up.

The Association of Encrustation and Ureteral Stent Indwelling Time in Urolithiasis and KUB Grading System.

PURPOSE: To evaluate the management of prolonged indwelling ureteral stents and the newly developed KUB (kidney, ureter, and bladder) grading system for the classification of encrusted stents in urolithiasis. METHOD: This study involved 69 patients that had indwelling and forgotten ureteral stents for more than 6 months after urolithiasis treatment. They were categorized into 4 groups based on indwelling time and were reviewed retrospectively. Patients whose ureteral stent could not be removed with simple cystoscopy were graded according to stone surface area and the KUB system. RESULTS: The mean stent indwelling time was 23.1 months. Stone burden in KUB and, in proportion to that, total KUB (T) score showed increased association that was directly proportional to indwelling time (p < 0.001, p = 0.008). Surgical intervention was required in 73.9% of patients. Among patients requiring surgery, 78.4% were treated in a single session and multi-modal interventions were performed in 70.5%. K score ? 3 was found to be associated with multiple surgery requirements (odds ratio [OR];11.25, %95 confidence interval [CI]:2.132-59.375),multi-modal procedure requirements (OR;16.50, %95 CI:3.434-79.826 ), and lower stone-free rates (p = 0.04). Bscore ? 3 was associated with multi-modal procedure requirements (OR;8.90, %95 CI:1.052-75.462). U score ? 3and T score ? 9 were associated with an operating time >180 minutes (p < 0.001, p = 0.008). CONCLUSION: Prolonged indwelling time of the ureteral stent in urolithiasis is associated with increased encrustation and stone burden. Since the KUB system specifies stone burden and its particular localization, it can be used as a simple, convenient method for the planning treatment of encrusted ureteral stents.

Does Tadalafil Increase The Uptake of Finasteride into Prostate Tissue? A Biochemical and Histological Evaluation in Rats.

PURPOSE: To histopathologically and biochemically evaluate the hypothesis that tadalafil increases the uptake of a second medication into the prostate tissue by increasing the blood supply in the prostate. METHODS: Forty 12-week-old Sprague Dawley male rats were equally divided into 5 groups and were administered drugs orally as follows: Group 1 - no drugs, Group 2 - 10 days of finasteride, Group 3 - 10 days of finasteride + tadalafil, Group 4 - 30 days of finasteride, and Group 5 - 30 days of finasteride + tadalafil. At the end of 10 days of drug administration in Group1, 2, and 3, and at the end of 30 days of drug administration in Group 4 and 5,blood samples were collected from rats and analyzed for serum androgen levels. In addition, prostate tissues were removed for histological examination. RESULTS: The mean DHT level as well as the minimum and maximum epithelial thicknesses in Group 3 were lower than those in Group 2. However, there was no statistical significant difference (P = 0.989, P = 0.176, and P = 0.070, respectively). The mean DHT level as well as the minimum and maximum epithelial thicknesses in Group 5 were lower than those in Group 4. However, there was no statistical significant difference (P = 0.984, P = 0.147, and P= 0.478, respectively). The mean minimum and maximum epithelial thicknesses in Group 3 and Group 4 were not statistically different (P = 0.488 and P = 0.996, respectively). CONCLUSION: The similarity of the mean minimum and maximum epithelial thickness in Group 3 and Group 4 may be indicate that the combination therapy provides an early histological effect. However, the fact that there was no statistical significant difference between Group 2 and Group 3, and between Group 4 and Group 5, in terms of the mean DHT level and minimum-maximum epithelial thicknesses suggests that longer term studies with more rats are necessary to test the validity of our hypothesis.
