The mass measured approximately 13 mm and was not clearly palpable on physical examination. Scrotal magnetic resonance imaging showed a well-defined, lobulated, and multinodular mass within the right testis. As a malignant testicular tumor could not be excluded, a right high inguinal orchiectomy was performed for diagnostic and therapeutic purposes. Macroscopically, the excised specimen contained a solid yellow-white mass measuring 16×13×12 mm. Histopathological examination revealed proliferation of tumor cells with round nuclei and eosinophilic cytoplasm. Immunohistochemical staining showed that the tumor cells were positive for calretinin, focally positive for Melan-A, and negative for SALL4. Based on these findings, the diagnosis of a Leydig cell tumor of the testis was made. The patient's postoperative course was uneventful, and no evidence of local recurrence or distant metastasis was observed during 9 months of follow-up. Leydig cell tumors are rare, accounting for approximately 1-3% of all testicular tumors. To our knowledge, this case represents the 128th reported case of testicular Leydig cell tumor in Japan. We report this rare case and provide a review of the literature.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"72 3","pages":"103-107"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147821876","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}

Blood tests showed an elevated inflammatory response, and a computed tomography (CT) scan showed emphysematous cystitis. In addition, air bubbles were observed in the inferior vena cava, pulmonary artery, and brachiocephalic vein. We considered that they came from emphysematous cystitis. After admission to our hospital, we started antibiotics, placed a urethral catheter, and controlled the hyperglycemia. The patient's emphysematous cystitis resolved, and a CT scan performed on the 9th day of her hospitalization showed the disappearance of air bubbles. Emphysematous cystitis is caused by the accumulation of gas produced by gas-producing bacteria in the bladder wall or bladder cavity. It is a relatively rare disease with a high mortality rate of about 2-7%. Emphysematous cystitis with air bubbles in the venous system is rare. To our knowledge this is the first report of air bubbles in the brachiocephalic vein. In this report, we describe a case of emphysematous cystitis with air bubbles in the inferior vena cava, pulmonary artery and brachiocephalic vein.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"72 3","pages":"113-116"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147821903","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 patient wasa 26-year-old woman who had experienced urinary frequency since childhood. Two years prior to visiting our hospital, her symptoms worsened, leading her to seek medical attention for increased frequency and bladder pain. Cystoscopy revealed no Hunner's lesions, but a voiding diary indicated reduced bladder capacity. A trial of bladder hydrodistension was performed without symptomatic improvement. She was referred to our department for further evaluation and management. Pressure-flow study (PFS) showed reduced detrusor contractility with significant abdominal straining during voiding. Although there was no post-void residual, she experienced severe voiding pain, prompting initiation of CIC. While her symptoms improved, attempts to discontinue CIC resulted in pain recurrence, and she continued CIC for over two years. This case highlights the diagnostic value of PFS and the potential effectiveness of CIC in selected BPS patients.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"72 3","pages":"117-120"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147821908","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}

Computed tomography scan revealed a 3 cm urethral stone, and she was referred to our hospital for surgery. The patient had a history of tension-free vaginal tape (TVT) surgery for stress urinary incontinence approximately 15 years ago. When transurethral lithotripsy was initiated, the lower end of the stone was found near the external urethral meatus, and an attempt to push it into the bladder was unsuccessful. When fragmentation of the stone was performed using a Ho-YAG laser, exposure of the mesh, presumably from the previous TVT surgery, was detected. A loop electrocautery was used to remove as much of the exposed mesh and the stone as possible. Cystoscopic observation was not possible, but no stone recurrence or mesh-related complications have been noted six months after the surgery. Cases of urethral stones caused by mesh exposure in the urethra after TVT are rare, and we report this case together with a literature review.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"72 2","pages":"89-92"},"PeriodicalIF":0.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147575859","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}

Here we retrospectively analyzed clinical courses from four patients with colovesical or rectovesical fistulas diagnosed at our hospital between January 2024 and December 2024. Among the four cases, three were male, and one was female. Fever was the chief complaint in three of the four cases, and sigmoid diverticulitis was identified as the underlying disease in two cases. All patients underwent abdominal plain CT scan and cystoscopy. CT scan revealed intravesical air in all cases. In one case, there was a discrepancy between the fistula location identified on CT and cystoscopic findings. One patient underwent laparoscopic sigmoidectomy as curative treatment, with an uneventful postoperative course. In the three cases managed conservatively, laparoscopic colostomy was performed, and postoperative complications such as urinary tract infection and urethral catheter obstruction occurred. In our case series, cystoscopy was useful for assessing the fistula location accurately. Preoperative evaluation with cystoscopy should be considered, especially in patients scheduled for curative surgery.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"72 2","pages":"75-78"},"PeriodicalIF":0.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147575846","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}
