The relationship between depression, anxiety and lower urinary tract symptoms in men.

Purpose: Patients with lower urinary tract symptoms (LUTS) often experience comorbid depression and anxiety, yet the mechanisms underlying this association remain incompletely understood. This prospective study aimed to investigate the relationship between depression, anxiety, and LUTS in men. Materials and methods: A prospective study was conducted with 350 male patients who underwent urologic examinations at our institution from January 2021 to December 2021. Of these, 131 patients meeting the inclusion criteria were included. Various questionnaires, including the International Prostate Symptom Score (IPSS) and the Hospital Anxiety and Depression Scale (HADS), as well as LUTS examinations (prostate-specific antigen test, transrectal ultrasonography, and urine flowmetry), were administered. Results: Among the 350 patients, 131 were included in the analysis, with an average age of 58.0 ± 13.69 years. The total IPSS was 18.0 ± 8.69, with the average voiding symptom score at 8.7 ± 5.19 and the average storage symptom score at 6.0 ± 3.27. Both anxiety and depression were found to be correlated with LUTS (P < 0.05). After adjusting for age, hypertension, and diabetes, anxiety (but not depression) was significantly associated with LUTS based on regression analysis. Conclusion: Men with LUTS are more likely to experience anxiety. Therefore, it is essential to assess and address anxiety when managing men with LUTS.

Correlation between urine cytology results on the day after overnight continuous saline irrigation following transurethral resection of bladder tumor and bladder tumor recurrence.

PURPOSE: To investigate the relationship between urine cytology results after overnight continuous saline irrigation (OCSI) following transurethral resection of bladder tumor (TURBT) and bladder tumor recurrence in non-muscle invasive bladder cancer (NMIBC). MATERIALS AND METHODS: A retrospective study was conducted on patients diagnosed with NMIBC between 2016 and 2020 after undergoing TURBT at our hospital. All patients received OCSI following TURBT and had urine cytology test at postoperative 1 day. Urine cytology was classified into three groups: Negative, low-grade urothelial neoplasm (LGUN)+atypical urothelial cells (AUC), and suspicious for high-grade urothelial carcinoma (SHGUC)+high-grade urothelial carcinoma (HGUC). Recurrence-free survival (RFS) in each group was compared using the Kaplan-Meier method. Univariable and multivariable Cox regression analyses were performed to evaluate independent prognostic factors. RESULTS: A total of 172 patients were included in this study. Based on urine cytology group (after OCSI), RFS did not reach the median value in the Negative group. In the LGUN+AUC group, the median RFS was 615.00 days. In the SHGUC+HGUC group, the median RFS was 377.00 days. In survival analysis, the Negative group had a longer RFS than the SHGUC+HGUC group (p=0.013). However, Cox regression analysis showed that SHGUC+HGUC was not an independent prognostic factor for recurrence. CONCLUSIONS: Urine cytology results after OCSI following TURBT in NMIBC were associated with bladder tumor recurrence. Specifically, SHGUC or HGUC in urine cytology after OCSI showed earlier recurrence than negative cases. However, further research is needed to accurately determine whether it is an independent prognostic factor.

Clinical outcome and safety of holmium laser prostate enucleation after transrectal prostate biopsies for benign prostatic hyperplasia.

PURPOSE: This study aimed to assess the clinical outcome and safety of holmium laser enucleation of the prostate (HoLEP) following transrectal ultrasound-guided prostate biopsy (TR biopsy) in the treatment of benign prostate hyperplasia. MATERIALS AND METHODS: We retrospectively analyzed data from 556 patients who underwent HoLEP between 2014 and 2021. The patients were categorized into six groups: Group 1-A (n=45) underwent HoLEP within four months post TR biopsy. Group 1-B (n=94) underwent HoLEP more than four months post TR biopsy. Group 1-C (n=120) underwent HoLEP after a single TR biopsy. Group 1-D (n=19) underwent HoLEP after two or more TR biopsies. Group 1-total (n=139, group 1-A+group 1-B or group 1-C+group 1-D) underwent HoLEP post TR biopsy. Group 2 (control group, n=417) underwent HoLEP without prior TR biopsy. We examined perioperative parameters, safety, and functional outcomes. RESULTS: The age, body mass index, International Prostate Symptom Score (IPSS), uroflowmetry, and comorbid diseases between group 1-total and group 2 were comparable. However, group 1-total exhibited significantly elevated prostate-specific antigen levels and larger prostate volumes (p<0.01). Perioperative factors like enucleation time, enucleation weight, and catheterization duration were notably higher in group 1-total (p<0.01). All groups showed significant improvements in IPSS, postvoid residual urine, and maximum flow rate during the 1-year postoperative period (p<0.05). The rates of postoperative complications were similar between group 1-total and group 2. CONCLUSIONS: Enucleation time and catheterization duration were significantly longer in the TR biopsy group. However, postoperative complications were not significantly different between TR biopsy and non-TR biopsy groups.

Pelvic floor muscle exercise with or without duloxetine for postprostatectomy urinary incontinence: A retrospective single-center study.

This study aimed to evaluate the effectiveness of combined pelvic floor muscle exercise (PFME) and duloxetine treatment in the recovery from postprostatectomy urinary incontinence (PPUI). Participants were patients who underwent radical prostatectomy (RP) between 2018 and 2021 and who were able to attend follow-up appointments every 3 months for at least 12 months. Continence was defined as the use of ≤1 pad per day. PPUI was compared at each follow-up period by dividing the participants into the PFME group (PFME only after RP) and the PFME + DUL group (PFME and 30 mg duloxetine daily after RP). A total of 197 patients were included. No significant differences were observed in the baseline characteristics between the 2 groups. In the PFME group (n = 127), the PPUI was 77.17%, 27.56%, 17.32%, 12.60%, and 9.45% at 2 weeks, 3 months, 6 months, 9 months, and 12 months, respectively. In the PFME + DUL group (n = 70), the PPUI was 62.50%, 17.86%, 12.50%, 8.93%, and 5.36%, respectively, at the same follow-up period. At 2 weeks, the PFME + DUL group demonstrated a better incontinence rate than the PFME group (P = .019). However, no significant differences were found in the incontinence rates between the 2 groups at each follow-up period after 3 months. Compared to PFME monotherapy, the combination therapy of PFME and duloxetine has short-term effectiveness in improving PPUI, but it does not have a significant long-term impact. Therefore, for early recovery from PPUI, duloxetine should be administered for a short period during PFME.

The Efficacy and Safety of 'Inverted Omega En-bloc' Holmium Laser Enucleation of the Prostate (HoLEP) for Benign Prostatic Hyperplasia: A Size-Independent Technique for the Surgical Treatment of LUTS.

PURPOSE: To evaluate the safety, efficiency, and size-dependency of the 'Inverted omega En-bloc (Ʊ)' holmium laser enucleation of the prostate (HoLEP) in benign prostate hyperplasia (BPH) with lower urinary tract symptoms. MATERIALS AND METHODS: A retrospective analysis of 716 consecutive patients who underwent HoLEP under the care of a single surgeon from 2014-2021. These patients were treated using the 'Inverted omega En-bloc' HoLEP technique for BPH. The patients were divided into 3 groups: Group 1 (<40 mL, n=328), Group 2 (40-60 mL, n=221), and Group 3 (≤60 mL, n=167). Perioperative parameters, safety, and functional outcomes were assessed and analyzed. RESULTS: The perioperative parameters, like enucleation time (45.8±26.9 min), morcellation time (13.2±47.5 min), and catheterization duration (1.6±1.2 d) significantly differed to favor smaller prostate sizes (p<0.01). Significant improvements in the IPSS (total, voiding, storage, and quality of life), post-void residual urine, and maximum flow rate were observed 3 months post-HoLEP and continued during the 1-year follow-up period in all groups (p<0.01). The postoperative complications included urethral stricture in 11 patients (1.5%), bladder neck contracture in 12 (1.7%), urinary incontinence in 14 (2.0%), and bladder injuries in 4 (0.6%). Bladder neck contractures occurred only in Group 1. The postoperative surgical management for complications included urethral sounding (n=9, 1.3%), endoscopic internal urethrotomy (n=2, 0.3%), and re-HoLEP for bladder neck contractures in (n=12, 1.7%). The rate of re-HoLEP for regrowing adenomas was 15 (2.1%). Postoperative medications exceeding 6 months were α-blocker (n=22, 3.1%), cholinergics (n=16, 2.2%), anticholinergics (n=58, 8.1%), antidiuretics (n=18, 2.5%), and daily PDE5 inhibitor (n=38, 5.3%). Thirty-four patients (4.7%) had postoperative incidental prostate cancer. CONCLUSIONS: The inverted omega En-bloc HoLEP technique is safe and effective for the treatment of BPH. Moreover, 'Inverted omega En-bloc' HoLEP is a size-independent and effective method for all prostate sizes.

Robotic-assisted simple prostatectomy after prostatic arterial embolization for large benign prostate hyperplasia: Initial experience.

Background and objective: We aimed to evaluate the safety and efficacy of robot-assisted simple prostatectomy (RASP) after prostatic arterial embolization (PAE) in large benign prostatic hyperplasia (BPH). Material and methods: This retrospective study included 11 cases of PAE and subsequent RASP, performed on 11 patients with BPH from March 2018 to September 2020. Clinical information on the patients was collected before surgery and 3 months after surgery. For the quantification of lower urinary tract symptoms (LUTS), International Prostate Symptom Scores (IPSSs), prostate-specific antigen (PSA) levels, urinary peak flow rate (Qmax), voided volume (Vvol), and postvoid residual volume (PVR) were measured. Results: PAE and the subsequent RASP were successfully performed in all 11 patients. The mean total prostate volume was 129.7 ± 65.1 mL, and the transitional zone volume was 71.7 ± 5.9 mL. The mean resected prostate volume was 60.8 ± 26.1 mL. The mean hemoglobin level of the patients prior to PAE was 14.2 ± 2.3 g/dL, and one day after RASP, the hemoglobin level was 12.4 ± 1.9 g/dL. The outcome indicated that there was a considerable decline in IPSS and PVR after RASP was performed compared to before PAE (21.6 ± 9.4 vs. 10.6 ± 8.0 and 159.4 ± 145.8 mL vs. 43.9 ± 45.9 mL). Qmax and Vvol significantly improved after RASP was performed (7.6 ± 5.2 mL/s vs. 26.1 ± 12.6 mL/s; 114.2 ± 92.5 mL vs. 192.4 ± 91.8 mL, respectively). Conclusion: This research demonstrated that RASP could be performed safely and effectively after PAE in patients with large BPH.

Expression Patterns of ERα, ERß, AR, SIRT1, SIRT2, and SIRT3 in Prostate Cancer Tissue and Normal Prostate Tissue.

BACKGROUND/AIM: The purpose of this study was to examine the expression of estrogen receptor α (ERα) and ß (ERß), androgen receptor (AR), SIRT1, SIRT2 and SIRT3 in prostate cancer (PCa). MATERIALS AND METHODS: From October 2010 to January 2015, 70 patients who had undergone radical prostatectomy following a PCa diagnosis were enrolled in our study. Normal prostate tissue (NPT) and prostate cancer tissues (PCAT) were separated, and the expression of each receptor in each tissue was analyzed with immunochemical staining. Univariate and multivariate analyses were performed to identify factors affecting the development of PCa. RESULTS: ERß and AR were highly expressed in PCAT compared with NPT (p<0.05). SIRT2 was highly expressed in NPT and PCAT (p<0.05). Univariate and multivariate analyses showed that AR and SIRT2 affect PCa development. CONCLUSION: AR is a risk factor for PC, and SIRT2 is associated with a lower incidence of PCa.

Correlation Between Testosterone Replacement Treatment and Lower Urinary Tract Symptoms.

Lower urinary tract symptoms (LUTS) are a cluster of voiding symptoms, such as weak stream, hesitancy, intermittency, urinary frequency, urgency, and nocturia. LUTS are frequent in elderly men and it considered the ultimate clinical symptoms of benign prostatic hyperplasia. With aging, male hypogonadism is increased which is defined as decreased ability of the testes to produce sperm and sex steroids because of a pituitary/hypothalamic, or testicular deficiency. In academic andrology associations, the term "male hypogonadism" is commonly used to categorize testosterone deficiency. Testosterone deficiency syndrome (TDS) is defined as a decrease in serum testosterone accompanied by symptoms such as libido decrease, depressive disorder, erectile dysfunction, and fatigue. Although the mechanism about testosterone-replacement therapy (TRT) effects on men with hypogonadism is not yet identified, TRT has been shown to effectively relieve the symptoms of TDS as well as LUTS by several studies. Although the present review demonstrates the effectiveness and safety of TRT in men with TDS by prior studies, future large scale of clinical trials should be conducted to present more high-quality evidence to clinicians and patients.

Presence of leucocytes in prostatic secretions correlates with the severity of lower urinary tract symptoms.

We investigated the correlation between the presence of leucocytes in expressed prostatic secretion and the lower urinary tract symptom severity by retrospectively reviewing 699 men with lower urinary tract symptoms. The patients were evaluated by the International Prostate Symptoms Score and the Overactive Bladder Symptoms Score and underwent expressed prostatic secretion testing. Patients were classified into groups 1 and 2 based on the expressed prostatic secretion leucocyte count. The mean total and storage score of the International Prostate Symptoms Score, and mean total Overactive Bladder Symptoms Score were higher in group 1. Urine flow metrics showed that voided volume and maximum flow rate were lower in group 1. The scores for International Prostate Symptoms Score questions 4, 6 and 7 and Overactive Bladder Symptoms Score question 2 were higher in group 1 and showed a weak positive correlation with expressed prostatic secretion. Voided volume and maximum flow rate showed the strongest correlation, although International Prostate Symptoms Score question 7 and Overactive Bladder Symptoms Score question 2 were the only independent predictors of expressed prostatic secretion. Therefore, leucocytes in expressed prostatic secretion are associated with the lower urinary tract symptom severity, particularly nocturnal urination symptoms.

Relationship between Hypogonadal Symptoms, Sexual Dysfunction and Chronic Prostatitis in Middle-Aged Men by Self-Reported Questionnaires, even without Biochemical Testosterone Deficiency.

PURPOSE: To investigate the association of erectile dysfunction (ED), premature ejaculation (PE), and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in men with late-onset hypogonadism (LOH). MATERIALS AND METHODS: We reviewed the data of 408 enrolled men between January 2014 and January 2019. All participants completed the Androgen Deficiency in the Aging Male (ADAM), international index of erectile function-5 (IIEF-5), National Institutes of Health chronic prostatitis symptom index (NIH-CPSI), and premature ejaculation diagnostic tool (PEDT) questionnaires. Participants were divided by ADAM positive (ADAM+: Group 1) and ADAM negative (ADAM-: Group 2). RESULTS: Total of 289 subjects were in Group 1 and 119 were in Group 2. The mean age was 53.8±7.8 years. The mean total testosterone was 4.8±1.2 ng/dL and showed no differences between the groups (p=0.839). In Groups 1 and 2, ED (IIEF≤21) was identified in 233 (80.6%) versus 37 (31.1%), respectively (p<0.001). The prevalence of PE (PEDT≥9) was 112 (38.7%) versus 13 (10.9%) in Groups 1 and 2, respectively (p<0.001). However, PE (intravaginal ejaculation latency time<5 minutes) showed no differences between the groups (p=0.863). The incidence of chronic prostatitis (NIH-CPSI pain score≥4) showed significant differences with 49 (17.0%) versus 8 (6.7%) in Groups 1 and 2, respectively (p=0.007). IIEF-5 total score showed the significantly highest negative correlation (r=-0.313, p<0.001). CONCLUSIONS: Those who complained of LOH symptoms and positive results in the ADAM questionnaire need to be assessed concurrently with the above questionnaires. This could aid useful to detect of ED, PE, and chronic prostatitis co-occurrence.

Effect of preoperative urethral dilatation on preventing urethral stricture after holmium laser enucleation of the prostate: A randomized controlled study.

INTRODUCTION: We aimed to evaluate the effect of preoperative urethral dilatation during holmium laser enucleation of the prostate (HoLEP) on the prevention of urethral stricture. METHODS: A total of 72 patients without urethral stricture underwent HoLEP for benign prostatic hyperplasia (BPH). Recruited patients were randomly divided into two groups (groups A and B). Patients in group A (36 patients, experimental group) received preoperative urethral dilatation and patients in group B (36 patients, control group) did not. Each patient was evaluated at four weeks, 12 weeks, and 24 weeks after surgery. The effectiveness of preoperative urethral dilatation was evaluated based on the International Prostate Symptom Score (IPSS), peak urine flow rate (Qmax), voided volume, and post-void residual (PVR) volume. To diagnose urethral stricture, Qmax <10 mL/s, as assessed using uroflowmetry and findings of visualization through retrograde urethrography and urethroscopy, were used. RESULTS: Among 72 initial participants, 33 patients in group A and 31 patients in group B completed the experiment. Preoperative characteristics were well-balanced between groups. At each postoperative visit, there was no significant difference in voiding symptoms between groups. Two patients (6.06%) in group A and five patients (15.15%) in group B showed a Qmax <10 mL/s on uroflowmetry (p=0.013). On urethroscopy, no patient in group A (0%) and two patients in group B (6.45%) (p=0.021) showed urethral stricture after HoLEP. CONCLUSIONS: Preoperative urethral dilatation during HoLEP decreased the incidence of urethral stricture. This procedure could be useful to reduce the risk of urethral stricture after transurethral prostate surgery. One limitation of the current study is the single-centre design. Also, we sought to determine the efficacy of preoperative urethral dilatation for the prevention of urethral stricture after transurethral prostate surgery within a short time period, which could be another limitation of the study. Despite these limitations, to the best of our knowledge, the present study is the first reported prospective, randomized trial analyzing the safety and efficacy of preoperative urethral dilatation for the prevention of urethral stricture after transurethral prostate surgery.

Risk factors for postoperative urinary retention among women who underwent laparoscopic cholecystectomy.

OBJECTIVES: The aim of this study was to investigate the risk factors for postoperative urinary retention (POUR) among female patients by evaluating its occurrence in women who underwent laparoscopic cholecystectomy in Gyeongsang National University Hospital. METHODS: The medical records of female patients who had undergone laparoscopic cholecystectomy for gallbladder stones between March 2014 and February 2018 were reviewed. Information was collected regarding patient age, body mass index (BMI), creatinine, absolute neutrophil count, duration of the operation and anesthesia, the amount of fluid infused, American Society of Anesthesiologists (ASA) classification, and medical comorbidities, such as hypertension, diabetes, and lung, liver, heart, renal, and neurologic disease. Comparisons were made between the POUR and non-POUR groups, and both univariate and multivariate analyses were conducted. RESULTS: Seventeen of 591 patients (2.9%) developed POUR. There as a positive correlation between age and POUR (P = 0.040), and a negative correlation between BMI and POUR (P = 0.037). In addition, a history of neurologic disease was greater in the POUR group (P = 0.033), which also had a higher ASA class than the non-POUR group (P < 0.001). Multivariate analysis showed that a high ASA class was a risk factor for POUR (hazard ratio 3.01; 95% confidence interval 1.13-7.99; P = 0.027). CONCLUSIONS: Medical care providers need to be aware of the risk factors for POUR, which is likely to prolong hospital stay for Foley catheter placement. A high ASA class is an important risk factor for POUR among female patients, so medical staff need to provide proper preoperative management strategies for patients with a high ASA class.

Metabolic Syndrome Is an Independent Risk Factor for Acquired Premature Ejaculation.

PURPOSE: To determine the role of metabolic syndrome (MetS) as a risk factor for acquired premature ejaculation (PE) after considering the various risk factors, such as lower urinary tract symptoms, erectile dysfunction, hypogonadism, and prostatitis. MATERIALS AND METHODS: From January 2012 to January 2017, records of 1,029 men were analyzed. We performed multivariate analysis to identify risk factors for PE, including the covariate of age, marital status, International Prostate Symptom Score, International Index of Erectile Function (IIEF) score, National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) score, serum testosterone levels, and all components of MetS. Acquired PE was defined as self-reported intravaginal ejaculation latency time ≤3 minutes, and MetS was diagnosed using the modified National Cholesterol Education Program Adult Treatment Panel III criteria. RESULTS: Of 1,029 men, 74 subjects (7.2%) had acquired PE and 111 (10.8%) had MetS. Multivariate analysis showed that the IIEF overall satisfaction score (odds ratio [OR]=0.67, p<0.001), NIH-CPSI pain score (OR=1.07, p=0.035), NIH-CPSI voiding score (OR=1.17, p=0.032), and presence of MetS (OR=2.20, p=0.022) were significantly correlated with the prevalence of acquired PE. In addition, the Male Sexual Health Questionnaire for Ejaculatory Dysfunction scores and ejaculation anxiety scores progressively decreased as the number of components of MetS increased. CONCLUSIONS: MetS may be an independent predisposing factor for the development of acquired PE. Effective prevention and treatment of MetS could also be important for the prevention and treatment of acquired PE.

Analysis of Motion-dependent Clinical Outcome of Tumor Tracking Stereotactic Body Radiotherapy for Prostate Cancer.

BACKGROUND: To analyze clinical outcome of CyberKnife (CK) tumor-tracking stereotactic body radiotherapy (SBRT) for prostate cancer (Pca) according to the magnitude of intra-fractional prostate motion. METHODS: Medical records and daily treatment logs for 71 patients who received CK tumor-tracking SBRT were retrospectively analyzed. Statistical relationships between prostate motion and various outcome results, including local recurrence (LR), biochemical failure (BF), and treatment-related toxicity, were investigated in order to evaluate motion-dependent efficacy of tumor-tracking SBRT for Pca. RESULTS: In a total 71 patients, 3 (4.2%) patients with LR, 12 (16.9%) patients with BF, and 22 (31%) patients with grade-II or worse toxicities to rectal or bladder (22 to rectal, 22 to bladder and 8 patients to both) were observed in a median follow-up of 47 months. Magnitudes of intra-fractional tumor motion along superior-inferior, right-left, and anterior-posterior (AP) axes were 0.15 ± 0.31, 0.12 ± 0.19, and 0.73 ± 0.32 mm, respectively. Radial magnitude was estimated to be 1.0 ± 0.35 mm. Intra-fractional movement was not significantly correlated with tumor control. However, it was significant correlated with the incidence of grade-II or worse toxicity to rectum or bladder particularly when tumor motion was in the AP axis. CONCLUSION: Our quantitative results revealed that toxicity related to SBRT treatment was highly sensitive to intra-fractional prostate movements, although local-tumor control was not affected by such movements. Our results demonstrate that precise motion correction is essential in prostate SBRT, even if it seems to be small.
