Postoperative examination revealed a right pheochromocytoma, which was a large hypervascular tumor with a maximum diameter of 18 cm. The patient had a short stature and thoracic deformity associated with NF1, which posed a challenge in securing the surgical field in the upper abdomen during the resection procedure. Additionally, it was necessary to consider the vascular and bone fragility associated with NF1. A positioning simulation was performed in collaboration with other medical departments the day before surgery. On the day of the surgery, the patient was positioned in a magic bed, to allow for safe rotation. A wide surgical field was successfully secured by performing a thoracoabdominal opening with a midline upper abdominal incision and a diagonal incision at the 9th intercostal space. The intraoperative hemodynamics were stable, and the surgery was completed safely. The patient has been recurrence-free for approximately 2 years since the surgery. Patients with NF1 have various lesions that differ greatly from one individual to another, and each case requires an appropriate surgical approach.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"71 8","pages":"255-259"},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144972960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The right renal artery normally runs dorsal to the inferior vena cava. In precaval renal artery, vascular anomaly, the right renal artery, branching from the abdominal aorta, runs ventral to the inferior vena cava. Furthermore, the precaval renal artery is often an accessory artery and rarely a single main artery. Preoperative identification of these anomalies is important for successful surgery. Herein, we report a case of 71-year-old woman who visited our department after right renal cancer was detected on computed tomography (CT) performed to investigate the sigmoid colon cancer. Per CT findings, the right renal artery ran ventrally to the inferior vena cava and was the single main artery. The right renal artery abnormality was confirmed preoperatively, and robot-assisted laparoscopic partial nephrectomy (RAPN) was completed without any major intraoperative complications. Approximately 25-40% of the renal arteries are estimated to run abnormally. Among these, the prevalence of a precaval right renal artery is estimated to be 0.8-5.0%, and most are collateral arteries. Furthermore, the precaval right renal artery rarely serves as the single main artery. This report aims to describe a case in which RAPN was performed safely in a patient with a single main artery, the precaval right renal artery, as the course of the right renal artery was known preoperatively.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"71 8","pages":"281-284"},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144972996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A retrospective analysis was conducted on 48 cases of AML treated with TAE at our hospital between 2014 and 2022. The median follow-up period for imaging was 24 months (0-145 months), and that for blood tests was 19 months (0-117 months). Preventive renal artery embolization was performed in 36 cases, and emergency renal artery embolization was performed in 12 cases. The overall complication rate associated with embolization was 75% (36/48 cases), but there were no postoperative complications of Clavien-Dindo classification grade III or higher except for one case with blood transfusion, and there was no difference between the two groups. Renal function was evaluated by eGFR, and there was no difference in renal function changes before and after embolization between the two groups. Tumor reduction was observed in all cases, with no difference in tumor reduction effect. Reembolization was required in three cases after emergency renal artery embolization. TAE for rupture prevention significantly reduced rupture due to marked tumor reduction and did not result in a significant decline in renal function. Emergency TAE requires a prompt response and is more challenging, making the timing of preventive treatment crucial. With the improvement of embolic materials and techniques, the safety and efficacy of TAE have been increasing in facilities where TAE is feasible.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"71 7","pages":"213-219"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144785564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are few reports on its relationship with lower urinary tract symptoms (LUTS). We investigated changes in urinary symptoms in patients treated with androgen deprivation therapy (ADT) for prostate cancer. This retrospective study included 38 patients who underwent ADT prior to low-dose-rate brachytherapy for low-risk prostate cancer and had no LUTS before treatment at our hospital. The median duration of ADT was 4 months. Prostate volume significantly decreased after ADT (P＜0.001), while the total International Prostate Symptom Score (IPSS) showed a tendency to worsen (P＝0.053). When IPSS was divided into voiding and storage symptom scores, there was no significant worsening in the voiding symptom score (P＝0.29) ; however, there was a significant worsening in the storage symptom score (P＝0.011). In addition, we observed a significant increase in urinary frequency at night (P＝0.009) and a significant worsening of the Overactive Bladder Symptom Score (P＝0.035). Thus, we suggest that short-term ADT may reduce prostate volume ; however, it may also lead to LUTS, particularly urinary storage symptoms.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"71 7","pages":"221-225"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144785563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This report includes a review of the literature and details of a case in a 75-year-old male with concurrent primary follicular lymphoma and adenocarcinoma of the prostate. The patient was referred to our department due to prostate enlargement observed on CT and complaints of a decreased urinary stream. His PSA level was elevated at 8.9 ng/ml. MRI showed a PI-RADS category 4 lesion in the right peripheral zone of the prostate, with an estimated prostate volume of 60 ml. A transrectal prostate biopsy identified adenocarcinoma in two cores from the right base and one from the left apex, leading to a diagnosis of prostate cancer cT2aN0M0. Subsequently, the patient underwent robotic-assisted laparoscopic radical prostatectomy. Pathological findings confirmed adenocarcinoma in the right and left lobes (pT2a, pN0, EPE0, SV0, LVl1, RM0) and identified concurrent primary follicular lymphoma within the anterior fibromuscular stroma, which was positive for CD20, CD10 and Bcl-2. A complete clinical investigation, including an 18F-fluorodeoxyglucose positron emission tomography scan and bone marrow biopsy, revealed no involvement of other sites, and the patient was ultimately diagnosed with Ann Arbor stage IE lymphoma. No additional treatment was administered, and the patient has been followed up regularly. At six months postoperatively, there was no evidence of recurrence of either prostate cancer or lymphoma.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"71 6","pages":"197-202"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144576590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
