Introduction 45,X/46,XY mosaicism is a rare anomaly in sexual differentiation, presenting with diverse phenotypes and often leading to infertility due to abnormal gonadal development. Aims This report aims to present a case study of a 45,X/46,XY mosaic male patient with an ejaculatory disorder attributed to seminal vesicle dysplasia. Methods In this case study, diagnostic procedures encompassed blood tests, semen analysis, chromosomal examination, and imaging studies to assess gonadal morphology. Treatment strategies included attempted varicocelectomy, pharmacological intervention with amoxapine, and surgical testicular sperm extraction. Additionally, the patient underwent assisted reproductive techniques, specifically intracytoplasmic sperm injection (ICSI), to facilitate pregnancy for his wife. Results A 32-year-old man could not ejaculate, with post-orgasmic urinalysis revealing minimal sperm presence. Chromosomal analysis confirmed 45,X/46,XY mosaicism. Despite undergoing microsurgical varicocelectomy for clinical varicocele and receiving tricyclic antidepressants, no improvement in semen volume occurred. Imaging studies indicated ejaculatory disorder due to prostate and seminal vesicle aplasia. Consequently, surgical retrieval of testicular sperm was performed, leading to successful pregnancy via ICSI for his wife. Conclusion Our approach has effectively addressed ejaculatory disorder in 45,X/46,XY mosaic men, resulting in successful pregnancy. [ABSTRACT FROM AUTHOR]

Simple Summary: Enfortumab vedotin, a targeted therapy for advanced urothelial carcinoma, has shown efficacy, especially in those treated with platinum-based chemotherapy and immune-checkpoint inhibitors. The EV-301 phase III trial reported enhanced overall survival and response rates than conventional chemotherapy. However, its effectiveness in Japanese patients needs further real-world validation. Analyzing 6007 urothelial cancer patients treated with pembrolizumab, 563 subsequently received enfortumab vedotin, while 443 switched to docetaxel or paclitaxel. Results indicated the enfortumab vedotin group had an extended overall survival compared to the paclitaxel/docetaxel group (p = 0.013, HR: 0.71). Conclusively, enfortumab vedotin offers Japanese patients better overall survival prospects after pembrolizumab treatment than docetaxel or paclitaxel. Background: Enfortumab vedotin shows promise as a targeted therapy for advanced urothelial carcinoma, particularly in patients who have previously received platinum-based chemotherapy and an immune-checkpoint inhibitor. The EV-301 phase III trial demonstrated significantly improved overall survival and response rates compared to standard chemotherapy. However, more data, especially from larger real-world studies, are needed to further assess its effectiveness in Japanese patients. Methods: A total of 6007 urothelial cancer patients inducted with pembrolizumab as a second-line treatment were analyzed. Among them, 563 patients received enfortumab vedotin after pembrolizumab, while 443 patients received docetaxel or paclitaxel after pembrolizumab, and all were included in the study for efficacy as a life prolonging agent. Results: The enfortumab vedotin group showed a longer overall survival than the paclitaxel/docetaxel group (p = 0.013, HR: 0.71). In multivariate analysis, enfortumab vedotin induction was the independent risk factor for overall survival (p = 0.013, HR: 0.70). There were no significant differences in cancer-specific survival. Conclusions: Enfortumab vedotin prolonged the overall survival for Japanese advanced or metastatic urothelial carcinoma patients compared to paclitaxel or docetaxel after pembrolizumab treatment.

Objective: Urethral stenosis is a disease in which the lumen of the urethra becomes constricted by fibrosis. Such stenoses have been treated by urethral dilation using a bougie and optical internal urethrotomy (OIU). Recently, high‐pressure balloon dilation (BD) has been developed as a new treatment method for urethral stenosis. The present study compared the effectiveness of urethral dilation by BD and OIU. Methods: Twenty‐two patients of urethral stenosis were treated at Yokohama City University Medical Center between 2005 and 2015. Of these, 13 underwent BD, whereas OIU was performed in 9. BD was performed at 30 atm twice for 5 min each time. In OIU, an endoscopic knife was used to cut out the stenotic lesion in 3 directions. The endpoint was set as restenosis, which required additional surgical treatment, including BD, OIU, and the use of a urethral bougie. Results: The causes of urethral stricture were endoscopic surgery (n = 7; 31.8%), development after total prostatectomy (n = 4; 18.2%), iatrogenic reasons associated with catheter insertion (n = 5; 22.7%), development after a prostate needle biopsy (n = 3; 13.6%), and unknown (n = 3; 13.6%). The site of the stenotic lesion site was the anastomosis (n = 3; 13.6%), bladder neck (n = 6; 27.3%), prostatic urethra (n = 4; 18.2%), anterior urethra (n = 7; 31.8%), and membranous urethra (n = 2; 9.1%). The stenosis‐free rate was 84% for those undergoing BD and 22% for those receiving OIU. The median stenosis‐free time was significantly longer after BD than OIU (1675 vs. 244 days, respectively; P < .01). Conclusion: The stenosis‐free time was significantly longer after BD than OIU.

Background: Female urethral carcinoma is a very rare disease that accounts for 0.02% of malignant diseases in female patients.Case Presentation: A 70-year-old Asian Japanese woman with a urethral tumor was referred to our hospital to undergo further examination. Biopsy specimens showed urethral adenocarcinoma that was positive for prostate-specific antigen. Her serum prostate-specific antigen level before surgery was 34.4 ng/ml. Urethral tumor resection with pelvic lymph node resection was performed. Her serum prostate-specific antigen level decreased to < 0.01 ng/ml after surgery.Conclusions: We report a very rare case of Skene duct adenocarcinoma in a female patient with serum prostate-specific antigen elevation.

Introduction: We evaluated bone scan index (BSI) as a predictive biomarker for time to castration-resistant prostate cancer (CRPC) in patients with metastatic hormone-sensitive prostate cancer (mHSPC). Materials and Methods: We identified 85 consecutive mHSPC patients treated with first-line androgen deprivation therapy. We analyzed the correlations between time to CRPC and clinicopathological characteristics, including age, prostate-specific antigen (PSA) level, Gleason score, clinical TNM stage, hemoglobin, lactate dehydrogenase, C-reactive protein, and BSI. Results: The median BSI was 2.7%. Progression to CRPC occurred in 55 (64.7%) patients and the median time to CRPC was 12.9 months. In multivariate analysis, 3 significant risk factors for time to CRPC were identified: age (>73 vs. ≤73 years; hazard ratio [HR] 0.53), p = 0.038, PSA level (>270 vs. ≤270 ng/mL; HR 0.53, p = 0.038), and BSI (>2.7 vs. ≤2.7%; HR 2.97, p < 0.001). Conclusion: Age, PSA level, and BSI were found to be significant predictive factors for time to CRPC in patients with mHSPC. [ABSTRACT FROM AUTHOR]

Introduction and Objectives. An elevated neutrophil-to-lymphocyte ratio (NLR) has been suggested to be associated with a poor prognosis in several cancers. We evaluated the utility of an elevated NLR as a biomarker to predict the prognosis of metastatic castration-resistant prostate cancer (mCRPC) patients treated with cabazitaxel (CBZ). Methods. We analyzed 47 patients who received CBZ chemotherapy for mCRPC in our institutions. The NLR was calculated using the neutrophil and lymphocyte counts before CBZ chemotherapy. We determined the NLR cut-off value based on the sensitivity and specificity levels derived from area under the receiver operator characteristic curves for death. A multivariate analysis was performed to investigate the association between the NLR and the prognosis. Results. The median overall survival (OS) after CBZ was 10.0 months (range: 6.3–13.2). The median OS was shorter in patients with a high NLR (≥3.83) than in those with a low NLR (<3.83) (5.8 versus 13.2 months, p=0.018). In the multivariate analysis, the NLR, patient age, and lymph node (LN) metastasis were independent predictors of the OS (hazard ratio 3.01, p=0.030; hazard ratio 3.10, p=0.029; hazard ratio 12.38, p=0.001, resp.). Conclusions. NLR might be a useful prognostic biomarker in mCRPC patients treated with CBZ. [ABSTRACT FROM AUTHOR]

Background: The neutrophil-to-lymphocyte ratio (NLR) is reported as a biomarker for some solid malignant diseases. Thus far, however, no reports of the relationship between the NLR and adrenal tumors have been published. We analyzed the utility of the preoperative NLR as a biomarker for predicting the prognosis or diagnosis of malignant disease.Methods: A total of 59 patients with adrenal tumors (13 cases of malignant disease and 46 with benign disease) were analyzed in this study from February 2004 to June 2015 at our institute. The NLR was obtained just before adrenalectomy. The diagnosis of adrenal tumor was confirmed by a pathological examination of surgical specimens.Results: The NLR in malignant adrenal tumor specimens was significantly higher than in non-malignant specimens (p = 0.028). Adrenocortical carcinoma (ACC) showed the highest NLR among all adrenal tumors. In ACC, the higher NLR group (NLR ≥ 5) showed a significantly poorer overall survival than the lower NLR group (NLR < 5) (p = 0.032).Conclusions: In adrenal tumors, a higher NLR indicates a higher incidence of malignancy. The NLR might be a new biomarker for predicting the prognosis of adrenal tumor patients. [ABSTRACT FROM AUTHOR]

Introduction. Gemcitabine and cisplatin (GC) is a gold-standard first-line systemic chemotherapy for advanced urothelial carcinoma (UC). However, it may cause severe adverse effects such as renal toxicity, gastrointestinal toxicity, and neurotoxicity. Sarcopenia is the age-related loss of skeletal muscle mass. A correlation between sarcopenia and the oncological prognosis has been reported. In UC, several studies have noted that patients with sarcopenia had a greater incidence of complications and worse survival after radical cystectomy or chemotherapy. Our institute introduced gemcitabine and nedaplatin (GN) for UC patients with renal failure. We investigated whether the presence of sarcopenia predicted the prognosis of patients with advanced UC who were treated by GN chemotherapy. Methods. A total of 27 patients (male, n=21; female, n=6) received GN therapy for metastatic UC from 2005 to 2016. The institutional review board of Yokohama City University Hospital approved this study. The psoas muscle index (PMI, cm2/m2) was calculated using this formula: right psoas muscle area (cm2)/the square of the body height (m2). The overall survival (OS) of the high PMI group (male: ≥2.49, female: ≥2.07) and low PMI group (male: <2.49, female: <2.07) was compared. Results. Kaplan-Meier survival curves and a log-rank test revealed that the high PMI group had significantly better OS than the low PMI group (p=0.015). The mean survival of the high and low PMI groups was 561 days and 223 days, respectively. Conclusions. In the present study, we revealed that sarcopenia (a low psoas muscle volume) might be a predictive factor for poorer overall survival in patients with advanced urothelial carcinoma who are undergoing GN chemotherapy.

Introduction and Objectives. Neutrophil-to-lymphocyte ratio (NLR) has been suggested to be a simple marker of the systemic inflammatory response in critical care patients. We previously assessed the utility of NLR as a biomarker to predict tumor recurrence and cancer death in bladder cancer patients who underwent radical cystectomy. In this study, we evaluated the prognostic impact of NLR in bladder cancer patients who received gemcitabine and nedaplatin (GN) chemotherapy. Methods. A total of 23 patients who received GN chemotherapy for advanced bladder cancer were enrolled in this study. The cut-off point of NLR according to the sensitivity and specificity levels was derived from the area under receiver operator characteristics (AUROC) curve plotted for disease progression or overall mortality. Results. The NLR cut-off point was determined as 4.14 for both tumor progression and overall mortality. Median progression-free survival (PFS)/overall survival (OS) in the higher NLR group (NLR ≥ 4.14) and lower NLR group (NLR < 4.14) were 194/468 days versus 73/237 days, respectively. Kaplan-Meier analysis showed that higher NLR significantly correlated with poorer PFS (p=0.011) and OS (p=0.045). Conclusions. NLR may serve as a new biomarker to predict responses to GN-based chemotherapy in advanced bladder cancer patients and/or their prognosis. [ABSTRACT FROM AUTHOR]

Ductal adenocarcinoma is an unusual variant of adenocarcinoma of the prostate. A 73-yearold male was referred to our hospital for the further examination of an elevated prostatespecific antigen level of 23.4 ng/mL. Radical prostatectomy (RP) was performed based on the diagnosis obtained by a prostate needle biopsy. The RP specimen revealed ductal adenocarcinoma of the prostate with positive capsular penetration. We herein report a rare case of ductal adenocarcinoma of the prostate. [ABSTRACT FROM AUTHOR]

A 36-year-old male was referred to our department for further examination of asymptomatic gross hematuria emanating from a bladder tumor. Cystoscopy revealed a broad-based tumor 40 mm in diameter. Urinary cytology was negative. Preoperative magnetic resonance imaging suggested a muscle invasive tumor. Transurethral resection was performed, and the pathological findings revealed an inflammatory myofibroblastic tumor. We herein report a rare case of bladder inflammatory myofibroblastic tumor.

We determined whether prostate specific antigen (PSA) would decrease with immediate antiandrogen switching from bicalutamide (BCL) to flutamide (FLT) in patients receiving combined androgen blockade for advanced prostate cancer. From 2002 to 2006, 20 patients who showed PSA failure after first-line hormonal therapy with a luteinizing hormone-release hormone (LH-RH) agonist and BCL were enrolled. All patients were immediately switched from BCL to FLT, administered with an LH-RH agonist, as second-line combined androgen blockade (CAB). We evaluated the PSA response to second-line CAB. Eight patients (40%) were responsive, showing PSA decreases of at least 50%. The median (range) duration of the PSA response was 18.4 (3–26) months. Second-line CAB using FLT was effective in 40% of patients who received first-line CAB using BCL. The lower Gleason scores at the initial prostate biopsy probably reflect the response to second-line CAB. Responders showed significantly better OS and CSS in the determination of any PSA decline and 40% PSA decline. The median OS duration in nonresponders and responders (40% PSA decline) was 1433 days versus 3617 days. It is concluded that an immediate switch from BCL to FLT is effective for some CRPC patients after first-line CAB using BCL. [ABSTRACT FROM AUTHOR]

Introduction. The neutrophil-to-lymphocyte ratio (NLR), which can be easily calculated from routine complete blood counts of the peripheral blood, has been suggested to serve as a prognostic factor for some solid malignancies. In the present study, we aimed to determine the relationship between NLR in prostate cancer patients undergoing radical prostatectomy (RP) and their prognosis. Materials and Methods. We assessed NLR in 73 men (patients) who received RP for their prostate cancer. We also performed immunohistochemistry for CD8 and CD66b in a separate set of RP specimens. Results. The median NLR in the 73 patients was 1.85. There were no significant correlations of NLR with tumor grade (p=0.834), pathological T stage (p=0.082), lymph node metastasis (p=0.062), or resection margin status (p=0.772). Based on the area under the receiver operator characteristic curve (AUROC) to predict biochemical recurrence after RP, potential NLR cut-off point was determined to be 2.88 or 3.88. However, both of these cut-off points did not precisely predict the prognosis. There were no statistically significant differences in the number of CD66b-positive neutrophils or CD8-positive lymphocytes between stromal tissues adjacent to cancer glands and stromal tissues away from cancer glands and between different grades or stages of tumors. Conclusions. There was no association between NLR and biochemical failure after prostatectomy. [ABSTRACT FROM AUTHOR]

Background: The bone scan index (BSI) using a computer-aided diagnosis system for bone scans is expected to be an objective and quantitative clinical tool for evaluating bone metastatic prostate cancer. This study aimed to evaluate the pretreatment BSI as a prognostic factor in hormone-naive prostate cancer patients with bone metastases.Methods: The study included 60 patients with hormone-naive, bone metastatic prostate cancer that was initially treated with combined androgen blockade therapy. The BONENAVI system was used for calculating the BSI. We evaluated the correlation between overall survival (OS) and pretreatment clinicopathological characteristics, including patients' age, initial prostate-specific antigen (PSA) value, Gleason scores, clinical TNM stage, and the BSI. Cox proportional hazards regression models were used for statistical analysis.Results: The median follow-up duration was 21.4 months. Clinical or PSA progression occurred in 37 (61.7%) patients and 18 (30.0%) received docetaxel. Death occurred in 16 (26.7%) patients. Of these deaths, 15 (25.0%) were due to prostate cancer. The median OS was not reached. In multivariate analysis, age and the BSI were independent prognostic factors for OS. We evaluated the discriminatory ability of our models, including or excluding BSI by quantifying the C-index. The BSI improved the C-index from 0.751 to 0.801 for OS. Median OS was not reached in patients with a BSI ≤ 1.9 and median OS was 34.8 months in patients with a BSI >1.9 (p = 0.039).Conclusions: The pretreatment BSI and patients' age are independent prognostic factors for patients with hormone-naive, bone metastatic prostate cancer.

Background: The bone scan index (BSI), which is obtained using a computer-aided bone scan evaluation system, is anticipated to become an objective and quantitative clinical tool for evaluating bone metastases in prostate cancer. Here, we assessed the usefulness of the BSI as a prognostic factor in patients with metastatic castration-resistant prostate cancer (mCRPC) treated using docetaxel.Methods: We analyzed 41 patients who received docetaxel for mCRPC. The Bonenavi system was used as the calculation program for the BSI. The utility of the BSI as a predictor of overall survival (OS) after docetaxel was evaluated. The Cox proportional hazards model was used to investigate the association between clinical variables obtained at docetaxel treatment, namely PSA, patient age, liver metastasis, local therapy, hemoglobin (Hb), lactase dehydrogenase (LDH), albumin (Alb), PSA doubling time, and BSI and OS.Results: The median OS after docetaxel therapy was 17.7 months. Death occurred in 22 (53.7%) patients; all deaths were caused by prostate cancer. In multivariate analysis, three factors were identified as significant independent prognostic biomarkers for OS after docetaxel; these were liver metastases (yes vs no; HR, 3.681; p = 0.026), Alb (<3.9 vs ≥ 3.9; HR, 3.776; p = 0.020), and BSI (>1% vs ≤ 1%; HR, 3.356; p = 0.037). We evaluated the discriminatory ability of our models including or excluding the BSI by quantifying the c-index. The BSI improved the c-index from 0.758 to 0.769 for OS after docetaxel. CRPC patients with a BSI >1 had a significantly shorter OS than patients with a BSI ≤ 1 (p = 0.029).Conclusions: The BSI, liver metastases and Alb were independent prognostic factors for OS after docetaxel. The BSI might be a useful tool for risk stratification of mCRPC patients undergoing docetaxel treatment. [ABSTRACT FROM AUTHOR]

Background: The neutrophil-to-lymphocyte ratio (NLR), a simple marker of the systemic inflammatory response in critical care patients, has been suggested as an independent prognostic factor for several solid malignancies. We investigated the utility of pretreatment NLR as a prognosticator in patients who presented with metastatic prostate cancer.Methods: We first investigated the correlation between NLR and prostate-specific antigen (PSA) levels in 1464 men who had both tests and were found to have prostate cancer on their biopsies at our institution from 1999 to 2015. We then assessed the relationship between pretreatment NLR and the prognosis in 48 patients who were diagnosed with prostate cancer metastasized to the lymph node and/or bone.Results: The NLR value was significantly elevated in men with higher PSA than in those with lower PSA (p < 0.001). In patients with metastatic prostate cancer, NLR (cut-off point of 3.37 determined by the AUROC curve) was correlated with both cancer-specific (p = 0.018) and overall (p = 0.008) survivals.Conclusions: Pretreatment NLR may function as a new biomarker that precisely predicts the prognosis in patients with metastatic prostate cancer.

A 73-year-old male was referred to our department for further treatment of a right retroperitoneal tumor. Contrast CT showed a tumor mass measuring 33 × 26 mm in size with poor contrast enhancement. Because we were unable to rule out tumor malignancy, we planned an operation. The tumor was easily separated and removed without nephrectomy. Histological study revealed a schwannoma. It is rare for this kind of tumor to arise from the retroperitoneum (approximately 0.7% of all cases), in particular at the renal hilum. We herein report a rare case of retroperitoneal schwannoma arising from the renal hilum. [ABSTRACT FROM AUTHOR]

Introduction: Retroperitoneal tumor is often seen in urology clinical practice. To diagnose the tumor, tumor specimens must be obtained. However, in some cases, the tumor is penetrated by vessels around the ureter, and it may be difficult to detect the optimal spot for obtaining a specimen, even when performing open surgery. Case Presentation: A 53-year-old male patient was referred to our hospital for further examination of left back pain due to hydronephrosis. Enhanced computed tomography demonstrated ureter stenosis in front of the ilium, which was surrounded by a retroperitoneal tumor. The tumor was penetrated by blood vessels; therefore, we performed an open surgical biopsy on the suspicion of a retroperitoneal tumor using ureteroscopic assistance. The diagnosis of idiopathic retroperitoneal fibrosis was made according to the biopsy. Conclusion: We herein report the first case of a ureteroscopy-assisted biopsy for the pathological diagnosis of a retroperitoneal tumor. © 2015 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

The aging population is becoming a primary global problem. The most important alteration that occurs in the body with age, is the loss of skeletal muscle. Previously, sarcopenia, which is associated with the loss of skeletal muscle, has been reported to be associated with the prognosis of cancer and complications. The present study investigated the importance of sarcopenia with regard to the prognosis or postoperative complications of upper urothelial cancer patients who underwent nephro-ureterectomy. A total of sixty patients (male, n=44; female, n=16) underwent nephro-ureterectomy for upper urothelial carcinoma. The psoas muscle volume was calculated at the level of the umbilicus using axial computed tomography images obtained prior to nephro-ureterectomy. The psoas muscle index (PMI) was calculated by the following formula: (right side psoas muscle area at the level of the umbilicus mm2)/(body height m)2. The median and mean (± standard deviation) ages of the 44 patients were 71 and 68.0 years (± 12.2 years). The lower PMI group demonstrated a significantly poorer recurrence-free survival compared with the higher PMI group (634 vs. 2,317 days, P=0.005). In terms of the duration of postoperative admission, the long-admission group (≥13 days) demonstrated a significantly lower PMI compared with the short-admission group (≤12 days) (383.0 vs. 433.1, P=0.039). Although the overall survival of the two groups did not differ significantly, the lower PMI group tended to have a shorter survival period compared with the higher PMI group (P=0.080). Of the patients with upper urothelial carcinoma, the lower PMI group exhibited a longer postoperative admission period and poorer recurrence-free survival compared with the higher PMI group. The present findings suggest that sarcopenia is a meaningful factor that should be considered when selecting therapy for upper urothelial carcinoma. [ABSTRACT FROM AUTHOR]

Background: In most cases, prostate cancer metastasizes to the lymph nodes, bone, and liver. In very rare cases, it metastasizes to the ureter. Due to the difficulty in making a preoperative diagnosis, ureteral metastasis from prostate cancer is typically diagnosed after nephroureterectomy.Case Presentation: A 77-year-old Asian Japanese man with right hydronephrosis and hydroureter was referred to our hospital to undergo further examination due to the suspicion of ureteral cancer. He had been diagnosed 2 years previously with prostate cancer with a Gleason score of 4+5=9. He received radiotherapy and androgen deprivation therapy. A nephroureterectomy was performed for suspected right ureteral cancer. On the basis of a histopathological examination, poorly differentiated adenocarcinoma was suspected, and the tumor cells were positive for prostate-specific antigen immunohistochemically.Conclusions: We herein report a rare case of ureteral metastasis in castration resistant prostate cancer.

Background: An enterogenous cyst is a rare entity categorized as an intestinal cyst. In most cases, enterogenous cysts are seen in the mediastinum, peritoneal cavity, spinal canal, subarachnoid space, and cerebral ventricle.Case Presentation: A 14-year-old Asian (Japanese) boy reported feeling pain in his left groin, and a mass was found. We did not perform orchiectomy because intraoperative frozen sections showed no malignant findings. On histological examination the resected specimens contained columnar epithelium surrounded by smooth muscle. Based on these findings, an enterogenous cyst was diagnosed. Few cases of enterogenous cysts of the testis have been described.Conclusion: We encountered a case of an enterogenous cyst of a pediatric testis. [ABSTRACT FROM AUTHOR]
