The advancements in cancer therapy have improved the clinical outcomes of cancer patients in recent decades. However, advanced cancer therapy is expensive and requires good health care systems. For kidney cancer, no studies have yet established an association between clinical outcome and health care disparities. We used the mortality-to-incidence ratio (MIR) for kidney cancer as a marker of clinical outcome to compare World Health Organization (WHO) country rankings and total expenditures on health/gross domestic product (e/GDP) using linear regression analyses. We included 57 countries based on data from the GLOBOCAN 2012 database. We found that more highly developed regions have higher crude and age-standardized rates of kidney cancer incidence and mortality, but a lower MIR, when compared to less developed regions. North America has the highest crude rates of incidence, but the lowest MIRs, whereas Africa has the highest MIRs. Furthermore, favorable MIRs are correlated with countries with good WHO rankings and high e/GDP expenditures (p < 0.001 and p = 0.013, respectively). Kidney cancer MIRs are positively associated with the ranking of health care systems and health care expenditures.

Background and objectives: Prostate cancer (PCa) is a common malignancy in males and has a relatively slower progression than other cancers. Our goal was to evaluate the clinical role of SPARC (secreted protein acidic and cysteine rich, osteonectin), cwcv, and kazal-like domains’ proteoglycan 1 (SPOCK1) in PCa. Materials and Methods: SPOCK1 expression was studied through the immunohistochemical staining of specimens from 71 patients with PCa. The correlation between SPOCK1 expression and clinicopathological features was quantitatively analyzed. We used Kaplan–Meier analysis and Cox proportional hazard models to analyze the prognostic value. Results: Of 71 PCa patients, high SPOCK1 expression was more likely to be seen in those with an advanced stage (p = 0.018) of the disease and an advanced tumor (T) value (p = 0.014). Patients in Gleason grade groups 3 and 4 had significantly higher SPOCK1 expression (p = 0.044 and 0.003, respectively) compared to those of Gleason grade group 1. However, this trend was not observed in patients in Gleason grade group 5. For the survival analysis, although it was not statistically significant, patients with a high SPOCK1 expression had a shorter median overall survival (6.2 years) compared to those with low expression (7.8 years). Conclusions: High SPOCK1 expression may be related to advanced clinicopathological features and possibly a poor prognosis. Further analysis with a larger patient base would help clarify this issue.

Background: Upper urinary tract urothelial carcinoma (UTUC) is the most common malignancy occurring after kidney transplantation (KT) in Taiwan. The aim of this study was to investigate the association between native kidney hydronephrosis and UTUC in post-KT patients. Methods: From 2003 to 2018, we conducted a retrospective cohort study that enrolled 1005 post-KT patients, 67 of whom were subsequently diagnosed with UTUC. We divided patients into two groups based on whether or not they had UTUC. Multivariate analysis and Kaplan-Meier plot were used to evaluate if native kidney hydronephrosis was associated with post-KT UTUC. Results: The total cohort consisted of 612 men (60.9%) and 393 women (39.1%) with a mean age of 48.2 ± 12.0 at KT. The mean follow-up time was 118.6 ± 70.2 months, and mean time from KT to UTUC was 7.53 years. There was a significant gender difference with a female predominance among the UTUC patients (73.1% versus 26.9%, p < 0.001). Native kidney hydronephrosis occurred more frequently in the UTUC group (68.7% versus 4.8%, p < 0.001). Multivariate analysis showed that native kidney hydronephrosis and female gender were significantly associated with UTUC with odds ratios of 35.32 (95% CI, 17.99–69.36; p < 0.001) and 3.37 (95% CI, 1.55–7.29; p = 0.002), respectively. UTUC in the post-KT patients also showed aggressive pathological characteristics and a tendency toward bilateral lesions (41.8%). Conclusions: Native kidney hydronephrosis is significantly associated with post-KT UTUC patients in Taiwan. Native kidney hydronephrosis may be a deciding factor for standard nephroureterectomy and bladder cuff excision in selected patients. Nevertheless, almost half of the patients with kidney hydronephrosis do not present with UTUC at the end of our study.

A male urethral disruption injury is a urological emergency. Primary endoscopic realignment (PER) refers to reestablishment of urethral alignment via indwelling urethral catheter by cystoscope, which is recommended as the optimal emergent treatment approach for reducing the likelihood of complications following injury. However, the prior literature suggests the success rate of PER to be relatively low due to complicated urethral disruption. We report a modified PER approach that serves to improve both the success rate and safety of the treatment. A 19-year-old male patient presented with multiple pelvic fractures and complete urethral disruption following a high-velocity traffic accident. The patient’s abdominal computed tomography and retrograde urethrography results revealed complete urethral disruption at the bulbar urethra, with hematoma and contrast medium extravasation that extended into the extraperitoneal space. The conventional retrograde PER by cystoscope failed due to severe disruption and considerable hematoma. Modified simultaneous antegrade and retrograde PER was performed by means of semi-rigid ureteroscopy via a suprapubic Foley catheter and cystoscopy via the external urethra. An antegrade guidewire was passed through the bladder neck and then pulled out through the external urethral meatus with a cystoscope. Urethral continuity was achieved after a 16-Fr silicone Foley catheter was indwelled into the bladder along the guidewire. The patient recovered well, achieving voiding continence and avoiding further operation for urethral stricture. Modified PER via suprapubic Foley catheter represents a promising and safe treatment approach in patients with posterior urethral injuries.

Background: Benign prostatic hyperplasia (BPH) can be associated with lower urinary tract symptoms (LUTS) and potential avlterations in autonomic nervous system function, as reflected by heart rate variability (HRV). This observational study was designed to generate hypotheses regarding the differential impacts of surgical de-obstruction versus uroselective pharmacological blockade on autonomic nervous system equilibrium, HRV restoration, and symptomatic outcomes in men with BPH and bladder outlet obstruction. Methods: Data from a prospective cohort of 242 men undergoing TURP and 210 men receiving tamsulosin were analyzed. HRV parameters (standard deviation of normal-to-normal intervals [SDNN], low-frequency/high-frequency [LF/HF] ratio, total power [TP], very low frequency [VLF]) and International Prostate Symptom Score (IPSS) was assessed at baseline and 12 weeks. Propensity score matching (PSM) was used to address baseline differences in age, prostate volume, IPSS, and baseline SDNN. Inter-group comparisons used ANCOVA with baseline as a covariate. Results: After TURP, SDNN increased by 14.70 ms (40%; 36.97 ± 22.80 to 51.67 ± 27.59 ms; p = 0.032; paired Cohen’s d = 0.58), LF/HF decreased by 0.90 (55%; 1.63 ± 1.60 to 0.73 ± 0.52; p = 0.028; d = −0.76), TP increased by 1303 ms² (95%; 1367 ± 820 to 2670 ± 1420 ms²; p = 0.025; d = 1.12), and VLF increased by 810 ms² (85%; 950 ± 560 to 1760 ± 980 ms²; p = 0.030; d = 1.01). For tamsulosin, SDNN increased by 6.73 ms (18%; 38.12 ± 12.50 to 44.85 ± 11.20 ms; p = 0.004; d = 0.57), LF/HF decreased by 0.16 (8%; 1.95 ± 0.65 to 1.79 ± 0.55; p = 0.012; d = −0.27), TP increased by 559 ms² (39%; 1453 ± 620 to 2012 ± 580 ms²; p = 0.006; d = 0.93), and VLF increased by 355 ms² (35%; 1020 ± 450 to 1375 ± 420 ms²; p = 0.010; d = 0.82). Secondary p-values (LF/HF, TP, VLF) were adjusted via the Benjamini–Hochberg method; adjusted p > 0.05 was used for some. Inter-group differences in changes were significant (ANCOVA p < 0.01; partial η² = 0.12–0.22 for group factor). TURP was associated with greater IPSS reduction (−10.2 points; 18.5 ± 6.2 to 8.3 ± 4.1; p < 0.001) compared to tamsulosin (−5.3 points; 15.8 ± 5.6 to 10.5 ± 4.8; p < 0.001; d = −1.02; inter-group p < 0.001). PSM confirmed these associations with p < 0.01 for HRV changes. Change in SDNN was associated with IPSS improvement in multivariate regression (standardized β = −0.42, p < 0.01). Conclusions: In this observational study, TURP was associated with greater changes in HRV parameters and symptomatic improvement compared to tamsulosin. These findings are hypothesis-generating and require confirmation in long-term randomized trials.
