ABSTRACT
OBJECTIVES: To understand the real-world outcomes for patients with penile cancer in the Kyushu-Okinawa area before the introduction of practice guidelines in Japan. METHODS: We retrospectively collected medical information on patients with penile squamous cell carcinoma and penile intraepithelial neoplasia at 12 university hospitals and their affiliated hospitals in the Kyushu-Okinawa area from January 2009 to December 2020. Patients with unknown clinical stage were excluded. Patient background characteristics and survival, as well as pretreatment factors involved in survival, were investigated. RESULTS: A total of 196 patients were included. Patients with clinical stage 0, I, IIA, IIB, IIIA, IIIB and IV comprised 9.7, 26.0, 22.4, 2.6, 10.7, 14.3 and 14.3%, respectively. The median follow-up was 26 months, and the mean 5-year overall survival and cancer-specific survival rates were 74.3 and 79.8%, respectively. On univariate analysis, tumor diameter ≥ 30 mm, penile shaft tumor, Eastern Cooperative Oncology Group performance status ≥ 1, cT ≥ 3, cN ≥ 2 and cM1 were associated with significantly poorer cancer-specific survival. On multivariate analysis, pretreatment factors of cN ≥ 2 (hazard ratio, 32.5; 95% confidence interval, 5.08-208; P = 0.0002), Eastern Cooperative Oncology Group performance status ≥ 1 (4.42; 1.79-10.9; P = 0.0012) and cT ≥ 3 (3.34; 1.11-10.1; P = 0.0319) were identified as independent prognostic factors. CONCLUSIONS: The study revealed basic data for future penile cancer treatment and research, including survival rates according to clinical stages, and identified cN ≥ 2, Eastern Cooperative Oncology Group performance status ≥ 1 and cT ≥ 3 at initial diagnosis as independent prognostic factors. Evidence for penile cancer in Japan is particularly scarce, and future large-scale prospective studies are warranted.

Aim: To identify the risk factors for bruises and fractures from falls in patients with overactive bladder (OAB). Methods: We evaluated 1136 patients with OAB and aged ≥50 years who visited our hospital. Age, sex, frequency of nocturnal urination, and urinary incontinence type were investigated in the 360 eligible patients. Patients were divided into three groups: those patients without falls (no-fall group), those with fall bruises (bruise group), and those with fall fractures (fracture group). The risk factors for bruises and fractures in patients with OAB were evaluated using the logistic regression analysis. In addition, association between the bruises or fractures from falls and the behavior around urination during the night was investigated. Results: The multivariate logistic regression analysis showed that female sex (odds ratio (OR) 2.888, p = 0.030) and nocturnal urination frequency ≥3 times/night (OR vs. ≤2 times/night, 2.940; p = 0.040) were significantly associated with bruises. Nocturnal urination frequency ≥3 times/night (OR vs. ≤2 times/night, 2.835; p = 0.026) and urge incontinence (OR 3.415, p = 0.016) were significantly associated with fractures. Behavior around urination during the night was significantly associated with fractures (p = 0.009). Conclusion: In the real-world clinical setting, increasing nocturnal urination frequency is a common risk factor for bruises and fractures. Also, female sex and urge incontinence were the risk factors for bruises and fractures, respectively. OAB patients with urge incontinence would especially require aggressive intervention to prevent fractures during night-time voiding.

OBJECTIVES: To evaluate the management and outcome of idiopathic retroperitoneal fibrosis (iRPF) in Japan, and to identify its clinical biomarker. METHODS: We retrospectively analyzed 129 patients with iRPF treated between January 2008 and May 2018 at 12 university and related hospitals. Patients treated with glucocorticoid were analyzed to identify a predictive biomarker. These patients were classified into three groups according to overall effectiveness (no change: NC, complete response: CR, and partial response groups: PR), and each parameter was compared statistically. RESULTS: Male-female ratio was 5:1, and median age at diagnosis was 69 (33-86) years. Smoking history was reported in 59.6% of the patients. As treatment, 95 patients received glucocorticoid therapy with an overall response rate of 84%. As a result, serum concentration of IgG4 was significantly decreased in NC group compared with the other two groups (56.6 mg/dL vs. 255 mg/dL, 206 mg/dL, p = 0.0059 and 0.0078). ROC analysis was performed between the nonresponder (NC) and responder groups (CR + PR) to identify the cut-off value of serum IgG4 as a predictive marker. As a result, AUC of 0.793 was confirmed. CONCLUSIONS: Pre-treatment serum IgG4 concentration may have potential as a predictive biomarker of steroid treatment.
ABSTRACT
Due to its rarity, adrenal hemorrhage is difficult to diagnose, and its precise etiology has remained unknown. One of the pivotal mechanisms of adrenal hemorrhage is the thrombosis of the adrenal vein, which could be due to thrombophilia. However, detailed pathological evaluation of resected adrenal glands is usually required for definitive diagnosis. Here, we report a case of a cortisol-secreting adenoma with concomitant foci of hemorrhage due to antiphospholipid syndrome diagnosed both clinically and pathologically. In addition, the tumor in this case was pathologically diagnosed as cortisol-secreting adenoma, although the patient did not necessarily fulfill the clinical diagnostic criteria of full-blown Cushing or sub-clinical Cushing syndrome during the clinical course, which also did highlight the importance of detailed histopathological investigations of resected adrenocortical lesions.

OBJECTIVE: To study the risk factors for urolithiasis in patients with Crohn's disease. METHODS: This retrospective study included 1071 patients with Crohn's disease who were treated at a single center. Data pertaining to the following variables were analyzed: sex; age; type of Crohn's disease; number of intestinal resections; residual small intestine length; ileostomy; history of glucocorticoid therapy; and duration of Crohn's disease treatment. RESULTS: Of the 1071 patients, 34 (28 male and six female) had urolithiasis (urolithiasis group) and 1037 (711 male and 326 female) did not (non-urolithiasis group). The median residual small intestine length measured in the urolithiasis group (280.0 cm) was significantly shorter than that in the non-urolithiasis group (342.5 cm; P < 0.01). Significantly more patients in the urolithiasis group (14/34) received steroid medication than those in the non-urolithiasis group (213/1037; P < 0.01). On multivariate analysis, male sex (odds ratio 3.15; P < 0.05), history of glucocorticoid therapy (odds ratio 3.07; P < 0.05), and shorter residual small intestine length (odds ratio 0.99; P < 0.01) were risk factors for the development of urolithiasis in patients with Crohn's disease. CONCLUSION: Our results suggest that male sex, history of glucocorticoid therapy, and shorter residual small intestine length are risk factors for urolithiasis in patients with Crohn's disease.

BACKGROUND Before partial adrenalectomy for primary aldosteronism due to a primary adrenal adenoma, the aldosterone-producing tumor can be localized by segmental adrenal vein sampling (S-AVS). Cardiologists, who regularly perform percutaneous coronary intervention (PCI), or coronary angioplasty with stent, may not be familiar with the technique of S-AVS. A case of the use of S-AVS is reported in a patient who presented with primary aldosteronism and a right adrenal adenoma. CASE REPORT A 44-year-old man with a history of hypertension presented with a man in the posterior part of the right adrenal gland. He had hypokalemia, and a high plasma aldosterone concentration/plasma renin activity ratio. A captopril stress test confirmed the diagnosis of primary aldosteronism. Pre-operative S-AVS was performed using a microwire and microcatheter, which were advanced into the segmental adrenal vein using a 6.5 French guiding catheter and a Y-shaped connector, under biplane cine angiography guidance. S-AVS showed a high plasma aldosterone concentration in the right superior tributary adrenal vein draining the adrenal mass. Right partial adrenalectomy was performed. Postoperatively, the patient's blood pressure and plasma aldosterone levels normalized. CONCLUSIONS S-AVS can be performed relatively easily before partial adrenalectomy using a catheter system with biplane cine angiography, which is a technique that is familiar to cardiologists.

A 74-year-old man was initially diagnosed as having cT4N0M0 and Gleason score 5+4 prostate adenocarcinoma in 2012. Systemic therapy was initiated with luteinizing hormone-releasing hormone (LH-RH) agonist and bicalutamide, and serum prostate-specific antigen (PSA) levels fell to a nadir of 0.02 ng/ml from 25.55 ng/ml.After 3 years of initial treatment, the patient presented with metastatic castrate-resistant prostate cancer (mCRPC) with extensive bulky lymphadenopathy and a serum PSA of 4.81 ng/ml. Open biopsy of the left supraclavicular lymph node revealed metastasis by poorly-differentiated adenocarcinoma of prostatic origin. He continued to receive LH-RH agonist and bicalutamide and underwent seven courses of docetaxel (DOC) chemotherapy plus prednisolone. Computed tomography showed partial response in all but one metastatic pelvic lymph node, which gradually increased in size. The mCRPC response to DOC was heterogeneous, and DOC chemotherapy was stopped because of toxicity and progressive disease.Second-line hormonal therapy with enzalutamide and LH-RH agonist was started and after 6 months, computed tomography revealed complete response in the metastatic lymph nodes based on response evaluation criteria in solid tumors (RECIST); PSA levels decreased to 0.01 ng/ml. The patient has been in complete remission for 28 months.
ABSTRACT
Objectives We retrospectively investigated the clinical and endocrinological characteristics of adrenal incidentalomas. Methods We studied 61 patients who had been diagnosed with adrenal incidentalomas and had undergone detailed clinical and endocrinological evaluations while hospitalized. We used common criteria to diagnose the functional tumors, but for sub-clinical Cushing's syndrome, we used an updated set of diagnosis criteria: serum cortisol ≥1.8 µg/dL after a positive response to a 1-mg dexamethasone suppression test if the patient has a low morning adrenocorticotropic hormone (ACTH) level (<10 pg/mL) and a loss of the diurnal serum cortisol rhythm. Results Of the 61 patients, none (0%) had malignant tumors, 8 (13.1%) had pheochromocytoma, and 15 (24.6%) had primary aldosteronism; when diagnosed by our revised criteria, 13 (21.3%) had cortisol-secreting adenomas (Cushing's syndrome and sub-clinical Cushing's syndrome), and 25 (41.0%) had non-functional tumors. Compared with the non-functional tumor group, the primary aldosteronism group and the cortisol-secreting adenoma group were significantly younger and had significantly higher rates of hypokalemia, whereas the pheochromocytoma group had significantly larger tumors and a significantly lower body mass index. Conclusion Our study found a larger percentage of functional tumors among adrenal incidentalomas than past reports, partly because we used a lower serum cortisol level after a dexamethasone suppression test to diagnose sub-clinical Cushing's syndrome and because all of the patients were hospitalized and could therefore receive more detailed examinations. Young patients with hypokalemia or lean patients with large adrenal tumors warrant particularly careful investigation.

BACKGROUND Catheter-based renal sympathetic denervation has been reported to be effective for treatment resistance hypertension in Australia and Europe. However, in the blinded SYMPLICITY HTN-3 trial, renal denervation did not achieve a significant decrease in blood pressure (BP) in comparison to sham controls. There have been various discussions on the factors that influenced this result. CASE REPORT Two men on antihypertensive therapy underwent unilateral radical nephroureterectomy for cancer of the renal pelvis. When the renal artery adventitia was stripped and cauterized just before renal artery ligation, the measured BP of the 2 men increased after stripping adventitia and decreased gradually after cauterization of the renal artery. This was presumably due to removal of renal artery sympathetic nerves, similar to the mechanism of catheter-based renal sympathetic denervation, although anesthesia, fluid infusion, and/or mesenteric traction may have had an influence. CONCLUSIONS A similar strategy involving thoracolumbar sympathectomy was reported about 50 years ago. The clinically significant blood pressure reduction in these patients suggests renal denervation is effective.

Before surgery for primary aldosteronism (PA), localization is evaluated with adrenal vein sampling (AVS). A 56-year-old Japanese woman had a right adrenal mass, hypokalemia, and a high aldosterone/renin ratio. Stress tests confirmed the diagnosis of PA. Subsequently, preoperative AVS was performed and right adrenal hemorrhage (AH) occurred unexpectedly. Because hypertension persisted, laparoscopic right adrenalectomy was performed. Postoperatively, the blood pressure was normalized. Pathological examination revealed an adrenal cortical adenoma largely unaffected by necrosis and hemorrhage. Previous reports have also indicated that AH may not ameliorate PA. We discussed the clinical progress of AH and the measures to prevent causing AH.
ABSTRACT
A 69-year-old man was admitted to our hospital with a chief complaint of lymphatic edema of left arm. He had a past history of transurethral resection of the bladder tumor 5 years ago, and pathological diagnosis was urothelial carcinoma with micropapillary variant, G3 = G2, pT1. CT scan revealed bladder tumor with invasion of the rectum, and multiple lymph nodes swelling in the axilla, retroperitoneum and pelvis (cT4bN3M1). The patient underwent biopsies of the bladder wall and the left axillary lymph nodes, and pathologic examination revealed micropapillary carcinoma. Five courses of gemcitabine plus cisplatin (GC therapy) were perfomed, and bladder tumor and lymph node metastases reduced remarkably, with serum CA19-9 level decreasing from 172,000 U/ml to 106 U/ml. However, the patient died from recurrence 23 months after the start of GC therapy.

Skeletal muscle is a very rare location for the metastasis of renal cell carcinoma (RCC) and only one case of solitary metastasis to the psoas muscle has been reported. We present a 63-year-old male patient with late recurrence (14 years) after left side radical nephrectomy for RCC. He first visited Chikushi Hospital, Fukuoka University, Japan in January 2000 for a postoperative follow-up because he had shifted residence to the area. Follow-up was by abdominal computed tomography (CT) and chest X-ray. In December 2001, a CT scan showed a 1.5 cm enhanced mass in the right psoas muscle without any other metastasis. The mass was resected that month and histological study showed RCC metastasis.

The patient was a 77-year-old man who underwent radical cystectomy and ileal conduit urinary diversion due to bladder cancer in 1989. A stenosis of the right uretero-ileal anastomosis occurred in 1992, and of the left uretero-ileal anastomosis in 1999. These were treated with indwelling of a ureteral stent and percutaneous nephrostomy, respectively. He was admitted to our hospital for progressive renal dysfunction due to frequent pyelonephritis. We performed a reconstruction of the ileal conduit urinary diversion and after the removal of the bilateral ureteral stent he complained of nausea and general malaise. The laboratory data showed hyponatremia, hyperkalemia and azotemia, which were diagnosed as complication liked jejunal conduit syndrome. He was treated with hydration and salt supplementation. With regard to this case, we considered that a long ileal conduit close to the jejunum and renal dysfunction caused the complication liked jejunal conduit syndrome. Careful observation and follow-up laboratory examination should be performed if the patient has renal dysfunction and a long conduit near the jejunum is used for the ileal conduit.

PURPOSE: We clarified the risk of elevated creatine kinase (CK) and myoglobulinemia during incised muscle urological operations. MATERIALS AND METHODS: We retrospectively reviewed 58 consecutive cases of radical nephrectomy with muscle incision and 89 consecutive radical prostatectomies or radical cystectomies without muscle incision. Operations with or without muscle incision were divided into 2 groups depending on operative time (200 minutes or less and 201 to 400). Increases in CK and myoglobin were compared between the 2 groups, and between muscle incision and no muscle incision at each operative time. RESULTS: CK and myoglobin were proportionally increased according to operative time in operations without muscle incision but not in muscle incision operations, in which high CK and myoglobin were seen even with short operative times. CK and myoglobin were more increased in muscle incision operations than in those without incision with significance at each operative time. However, maximum CK and myoglobin were 2,220 IU/L and 3,600 ng/ml, respectively, in muscle incision operations. CONCLUSIONS: Even with short operative times surgeries with muscle incision are associated with a marked increase in CK and myoglobulinemia. However, CK and myoglobin are not sufficiently high for rhabdomyolysis with acute renal failure to develop.

Bacillus Calmette-Guérin (BCG) immunotherapy is increasingly being accepted for management of some bladder transitional cell neoplastic lesions. Mild adverse reactions occur frequently. However, an unusual complication of tuberculous epididymitis is reported. A 64-year old man presented with bilateral epididymal mass. Four months earlier he had seven treatments with intravesical BCG instillation (Tokyo 172 strain) for a grade 2 transitional cell carcinoma in situ. Bilateral epididymectomy was performed. Microscopic examination of the epididymis revealed chronic inflammation and necrosis with granulomas and Langhans' giant cells. After the operation, there were no further complications.
