AbstractIntroduction: There are conflicting results in the literature regarding the efficacy of retrograde intrarenal surgery (RIRS) in lower pole stones. This study aimed to evaluate RIRS outcomes in lower pole stones by forming matched case-control groups. Methods: The data of 491 patients who were diagnosed with kidney stones and underwent RIRS were retrospectively included in the study. A total of 209 patients with lower pole stones (Group 1) and 282 patients with pelvic stones (Group 2) were matched at a 1:1 ratio in terms of stone burden, stone density, preoperative double-J stenting status, and a previous history of shock wave lithotripsy, yielding 159 patients in each group. A computed tomography scan was performed to evaluate the stone-free status. The primary outcome was stone-free status 1 month after RIRS. Results: After case-control matching, the median age was 49 years (interquartile range [IQR]: 40–58) in Group 1 and 50 years (IQR: 35–60) in Group 2 (p = 0.388). The median stone burden values of Group 1 and Group 2 were 415.3 mm3 (IQR: 176.1–858.2) and 503.3 mm3 (IQR: 282.5–864), respectively (p = 0.100). After RIRS, stone-free status was achieved by 126 of the 159 (79.2%) in Group 1 and 133 of the 159 (83.6%) patients in Group 2 (p = 0.387). The groups were similar in terms of perioperative complications (4.4% in Group 1 and 3.8% in Group 2, p = 0.777), postoperative complications (13.8% in Group 1 and 10.3% in Group 2, p = 0.393), and median operation time (60 min in both, p = 0.230). A longer median fluoroscopy time was noted in Group 1 compared to Group 2 (26 s and 3 s, respectively, p = 0.013). Conclusions: Stone-free rates and complications were comparable between the patients with lower pole and pelvic stones after RIRS. However, lower pole stones are associated with longer fluoroscopy time. RIRS can be performed effectively for the treatment of lower pole stones.

AbstractIntroduction: Recurrent urinary tract infections (UTIs) are common in individuals with neurogenic lower urinary tract dysfunction (NLUTD) and greatly affect their quality of life. There is currently no established prophylactic measure based on evidence. We have therefore evaluated the effects of a horseradish root and nasturtium herb product on the frequency of UTIs in a retrospective cohort. Methods: Clinical data of patients with chronic NLUTD who were receiving the phytotherapeuticum for at least 12 months were analyzed. The number of UTIs was categorized as no UTIs, sporadic UTIs (1–2/year) and recurrent UTIs (≥3/year). The change in the annual number of patient-reported symptomatic UTIs and antibiotic prescriptions was investigated. Results: Data of 43 individuals (mean age 49 ± 13 years, median NLUTD duration 17.9 years) were analyzed. The proportion of individuals with recurrent UTIs decreased significantly (p < 0.0001) from 58.1% (42.1–73.0%) to 23.3% (11.8–38.6%) during phytotherapy, whereas the proportion of individuals without UTIs increased significantly (p = 0.001) from 14.0% (5.3–27.9%) to 39.5% (25.0–55.6%). In addition, there was a significant (p = 0.008) decrease in the number of antibiotic prescriptions. Conclusion: Prophylactic treatment with horseradish root and nasturtium herb seems to be a promising option for the prevention of UTIs.

AbstractIntroduction: Renal cancer (RC) is not typically symptomatic until it reaches a considerable size and an advanced stage [World J Oncol. 2020;11(3):79–87]. The 5-year survival rate for metastatic renal cancer (mRC) is estimated at 13% [CA Cancer J Clin. 2021;71(1):7–33]. Health-related quality of life (HRQoL), obtained as patient-reported outcomes (PRO), reflects the patient’s subjective perception of the disease and treatment impact on their normal activity and well-being [Lancet Oncol. 2016;17(11):e510–4]. Measuring HRQoL can facilitate doctor-patient communication, aid in decision-making, and improve clinical outcomes [Eur Urol Focus. 2020;6(1):26–30]. We will analyse the baseline quality of life of patients diagnosed with mRC, who are candidates for systemic treatment, in our setting, as measured by responses to the NCCN-FKSI 19 questionnaire. Methods: We analysed 78 consecutive patients diagnosed and treated for mRC from September 2012 to September 2019. We described the baseline questionnaire responses of our patients before initiating systemic treatment and analysed their responses. Results: Over 60% of the patients reported some degree of lack of energy or fatigue, 60.8% were very or extremely worried about their disease worsening, and 47.9% had some issues related to rest. Additionally, 26.8% of the patients were not at all satisfied with their quality of life at that time. Conclusions: Patients diagnosed with mRC exhibit deterioration in their quality of life, mostly showing asthenia and concern about their disease. The quality of life of “real-life patients” seems to be worse than that of those included in clinical trials.

AbstractIntroduction: Studies comparing refluxing versus non-refluxing ureteric implantation in continent cutaneous urinary diversion (CCUD) are scarce and often characterized by heterogeneous study populations. This work therefore aimed at comparing both techniques regarding long-term outcomes in a propensity-scored approach. Methods: We identified n = 19 patients, totaling n = 38 renal units (RU), who underwent CCUD surgery at our hospital out of a pool of 120 patients. Of these 38 RU, 27 RU were implanted via refluxing ureteric implantation utilizing various procedures due to special intraoperative circumstances (short ureters, damage due to radiation). In terms of preoperative renal function, a comorbidity index (Age-Adjusted Charlson Comorbidity Index [ACCI]), and gender, we compared them to n = 38 patients with a total of 76 RU with non-refluxing ureteric implantation in all RU (1:2 matching). The mean follow-up was 56 (IQR: 23–112) months. Results: Long-term renal function was comparable in CCUD patients receiving refluxing versus non-refluxing ureteric implantation (estimated glomerular filtration rate: 63.11 mL/min vs. 71.7 mL/min, p = 0.22) with an average decline of 17.4 mL/min and 13.69 mL/min during the follow-up period, respectively. Also, the rate of new-onset chronic kidney disease (CKD) (both 15%, p = 1), the need for alkalizing medication, or the number of pyelonephritis episodes did not significantly differ between the groups. In Cox regression analysis, ACCI was the single most predictive parameter for the development of new-onset CKD (HR: 1.71 [1.10–2.66], p = 0.0167). None of the RU in the refluxing group needed revisional surgery concerning the ureterointestinal anastomosis, whereas 7 RU of the non-refluxing group did. Conclusions: Our study confirms that refluxing ureteric implantation in CCUDs is a valid and safe procedure regarding long-term renal, metabolic and functional outcomes. Our data also suggest that patients should be counseled according to their comorbidities regarding long-term renal function.

AbstractIntroduction: Systematic evaluations focusing on the perception of body image and social support in relation to quality of life (QoL) outcomes in patients radical cystectomy (RC) with urinary diversion (UD) are currently lacking. This study investigated the relationship between body image perception, social support, and QoL in bladder cancer patients who underwent RC with UD. Methods: A cross-sectional survey was conducted using validated general oncology tools to assess QoL in relation to newly implemented tools assessing body image perception and social support. Body image perception was assessed with the Self-Image Scale, and social support was assessed using the Illness-Specific Social Support Scale. Logistic regression models were used to analyze factors associated with QoL and body image, respectively. Results: The survey revealed a significant association of body image perception with QoL, as well as social support with body image perception. This is the first study to systematically evaluate these psychosocial factors in the context of QoL for RC patients, highlighting their critical role in patient-reported outcomes. Conclusion: Body image perception and social support are important psychosociological factors that affect QoL of bladder cancer patients post-RC. Targeted psychosocial interventions could be promising for improving QoL patients post-RC.

AbstractIntroduction: Benign prostatic hyperplasia (BPH) is a common condition in older men, marked by the noncancerous enlargement of the prostate gland. Inflammation of the prostate plays a significant role in the progression of BPH and the symptoms it causes. The objective of this study was to create a predictive model for prostatic inflammation in men with BPH based on important clinical factors. Methods: A retrospective cohort study was conducted with 137 patients diagnosed with BPH. Data collected included various factors such as age, prostate volume (PV), preoperative international prostate symptom score, preoperative maximum urine flow rate (Qmax), preoperative post-void residue, weight of the excised tissue, body mass index, fasting blood glucose (FBG), cholesterol levels, prostate-specific antigen, blood calcium, blood phosphorus, blood uric acid, triglycerides, hypertension status, and presence of prostate calcifications. Multivariate logistic regression and LASSO regression analyses were performed to identify significant predictors and develop a nomogram. The model’s performance was evaluated using receiver operating characteristic curves, calibration plots, and decision curve analysis (DCA). Results: Among the patients, 9.49% showed no signs of prostatic inflammation, while 22.63% had mild, 47.45% had moderate, and 20.44% had severe inflammation. Factors such as PV, FBG, and prostate calcification were identified as important predictors of prostatic inflammation. The predictive model developed exhibited strong discrimination and calibration, as evidenced by a high area under the curve value, indicating reliable predictive accuracy. DCA further validated the clinical usefulness of the nomogram. Conclusion: The developed nomogram, incorporating PV, FBG, and prostate calcification, effectively predicts prostatic inflammation in men with BPH. This tool can aid in early intervention and targeted treatment, potentially improving patient outcomes. Further validation in diverse populations is recommended to enhance its generalizability and clinical applicability.

AbstractIntroduction: The objective of this study was to investigate the relationship between the activity of neutral α-glucosidase in seminal plasma and semen quality and to explore the effect of secretory capability of the epididymis on male fertility. Methods: A retrospective analysis of 542 men treated in the Center for Reproductive Medicine and Infertility from February to December 2022, the semen parameters and neutral α-glucosidase were tested and compared among different groups. These 542 men included normozoospermia, oligospermia, asthenospermia, and teratozoospermia. Results: There was statistical difference in neutral alpha-glucosidase (NAG) level among different groups with different sperm concentration, motility, and morphology (p < 0.001). The NAG activity in seminal plasma was positively correlated with ejaculate volume and sperm concentration; meanwhile, a very weak positive correlation was found between NAG level and sperm motility, sperm morphology, respectively. Conclusions: Our results indicated that the secretion of NAG affected the volume, concentration, motility, and morphology of sperm to a certain extent. Given that NAG is a specific and marker enzyme in epididymis, where is the site of sperm maturation, we can conclude that there is a close relationship between NAG and sperm quality. Therefore, seminal plasma NAG has a definite clinical value in helping diagnosis of male infertility.

AbstractIntroduction: To study the clinical symptoms and psychological status of biofeedback electrical stimulation combined with pelvic floor muscle training during the treatment of mild stress urinary incontinence (SUI) after holmium laser enucleation of the prostate (HoLEP). Methods: Group A was treated by biofeedback and electrical stimulation; Group B was treated by pelvic floor muscle training; and Group C was treated by biofeedback and electrical stimulation combined with pelvic floor muscle training. Patients in the 3 groups had follow-up evaluations every 8, 16, and 24 weeks. Clinical symptoms of urinary incontinence were assessed using the 24-h urinary pad test, the Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF); and psychological status was evaluated using the modified Hospital Anxiety Depression Scale (HADS). Results: The results of ICIQ-UI-SF showed that there were differences within and between the three groups at 8 weeks, 16 weeks, and 24 weeks (p < 0.05). The results of the 24-h pad tests were similar (p < 0.05), except for no difference between group B and group C at 8 weeks (p > 0.05). In the study with the score of HADS >35, the differences among the three groups were statistically significant (p < 0.05). There was no significant difference among the three groups at 0 and 8 weeks (p > 0.05). There were differences in the results between group C and the other two groups at 16 and 24 weeks of treatment (p < 0.05). For patients with HADS <35 at week 0, the results were basically the same except for the difference between groups at week 8. HADS of all patients were no statistical difference (p > 0.05). Conclusions: Biofeedback electrical stimulation combined with pelvic floor muscle training is an efficient nonsurgical combination therapy for the symptoms of SUI after HoLEP for benign prostatic hyperplasia. In addition, the recovery of the patient’s psychological state does not coincide with the recovery of urinary incontinence; therefore, we propose that patients still need additional psychological treatment after SUI disappears.

AbstractBackground: Urinary system stones are a common clinical disease, with significant differences in incidence and recurrence rates between different countries and regions. The etiology and pathogenesis of urinary system stones have not been fully elucidated, but many studies have found that some bacteria and fungi that are difficult to detect in urine constitute a unique urinary microbiome. This special urinary microbiome is closely related to the occurrence and development of urinary system stones. By analyzing the urinary microbiome and its metabolic products, early diagnosis and treatment of urinary system stones can be carried out. Summary: This article reviews the relationship between the urinary microbiome and urinary system stones, discusses the impact of the microbiome on the formation of urinary system stones and its potential therapeutic value, with the aim of providing a reference for the early diagnosis, prevention, and treatment of urinary system stones. Key Messages: (i) Urinary stones are a common and recurrent disease, and there is no good way to prevent them. (ii) With advances in testing technology, studies have found that healthy human urine also contains various types of bacteria. (iii) Is there a potential connection between the urinary microbiota and urinary stones, and if so, can understanding these connections offer fresh perspectives and strategies for the diagnosis, treatment, and prevention of urinary stones?

AbstractIntroduction: Although albumin-globulin ratio (AGR) has been used in the prognostic assessment of multiple solid malignancies, so far no research has confirmed the prognostic significance of AGR as a biomarker for urachal carcinoma. We analyzed the relationship between AGR and prognosis in urachal carcinoma, aiming to identify a promising prognostic biomarker for urachal carcinoma. Methods: We reviewed the clinical data of 25 patients diagnosed with urachal carcinoma in the Xiangya Hospital, Central South University, from January 2008 to October 2021. The best cut-off value of preoperative AGR was determined according to the receiver operator characteristic curve. The Kaplan-Meier curve was used to analyze the effect of preoperative AGR on the overall survival (OS) and relapse-free survival (RFS) of patients. Cox proportional hazards model was used to analyze prognostic factors including preoperative AGR. Results: The best cut-off value of preoperative AGR in urachal carcinoma patients is 1.45. Low preoperative AGR is significantly associated with worse OS and RFS. Univariate analysis and multivariate analysis indicated that low preoperative AGR is an independent and reliable factor to predict poor prognosis, OS, and RFS in urachal carcinoma patients. Conclusion: Urachal carcinoma patients with low preoperative AGR have worse prognosis, and preoperative AGR is a valuable prognostic indicator for urachal carcinoma research.
