The herniation of the ureter through the sciatic foramen presents as a particularly uncommon variant of this condition. A 62-year-old woman was referred to our hospital from a family practioner with symptoms of fever and septic shock. Subsequent computed tomography imaging revealed left hydroureteronephrosis without clear evidence of ureteral stones or ureteral tumors and that the lower part of the ureter was shifted to the outside of the cavum pelvis minor from the greater sciatic foramen. She was diagnosed with ureterosciatic hernia, and a left retrograde ureteral stent was indwelled. Her hemodynamic status improved and the ureteral stent was removed after ureteral migration became normal. However, three months later, left ureterosciatic hernia recurred. Therefore, we performed laparoscopic vesicoureteral neoanastomosis and native tissue repair of hernia by uterine appendages. The postoperative course was uneventful. We believe this is a durable repair although longer follow-up is needed to establish the longevity of our treatment modality.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"71 5","pages":"159-164"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144235492","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}

On the contrary, the majority of men who have varicocele show normal semen parameters. This study aimed to clarify the pathophysiology of abnormal semen findings associated with varicocele by evaluating the total antioxidant capacity in seminal plasma and serum. Sixty patients with clinical varicocele were included in this study. Of the 60 patients, 22 men had scrotal pain caused by varicocele with normal semen parameters, and 38 men had abnormal semen parameters as defined by the 2010 World Health Organization criteria. Before the investigation, semen samples were collected. Total antioxidant capacity in serum and seminal plasma was analyzed by colorimetric assay and the relationship between semen parameters and total antioxidant capacity was evaluated. Positive associations were found between antioxidant capacity in seminal plasma and concentration (r＝0.364, P＝0.004), motility (r＝0.254, P＝0.050), and total motile sperm count (r＝0.468, P＜0.001). In multivariate analysis, higher total motile sperm count showed a significant positive relationship with higher total antioxidant capacity in seminal plasma (P＝0.001). Our results indicated that the total antioxidant capacity of seminal plasma might affect varicocele-related male infertility.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"71 5","pages":"137-143"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144235493","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 45-year-old woman with kidney failure of unknown etiology who was on peritoneal dialysis for 2 years was admitted after receiving immunosuppressive drugs at an outpatient clinic. The platelet count gradually decreased and eventually reached a level that could interfere with surgery. Mycophenolate mofetil was considered the cause of thrombocytopenia. Thus, it was discontinued, which increased the platelet count. The patient also received platelet transfusion, and renal transplantation was successfully performed as planned. The patient did not develop hemorrhage after the transplantation. The pretransplantation administration of mycophenolate mofetil was suspected to have caused thrombocytopenia in this patient. Hence, sudden decline in platelet count before surgery should be promptly investigated to identify potential causes in order of their likelihood. It is important to confirm that there is no evidence of platelet consumption or destruction.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"71 5","pages":"149-153"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144235491","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}

On admission, his systolic blood pressure was in the 70s mmHg range, and his pulse was around 60 bpm. Initial resuscitation efforts included fluid administration with normal saline and vasopressor support with noradrenaline. A contrast-enhanced abdominal computed tomographic (CT) scan revealed multiple simple intraparenchymal lacerations in the right kidney, accompanied by perinephric hematoma, and peripheral extravasation of contrast at the right renal artery. There was also partial luminal narrowing of the main right renal artery, raising concern for the development of a false lumen. The renal injury was classified as grade IIIa, PV, H1, according to the Japanese Association for the Surgery of Trauma (JAST) criteria. Although interventional radiology (IVR) was considered for management of perinephric hematoma, it was ultimately deemed inappropriate given the potential presence of a false lumen in the main right renal artery. The patient's hemodynamic status improved, and vasopressors were discontinued by the time of the follow-up CT scan. Despite subsequent imaging showing hematoma enlargement, the patient remained hemodynamically stable, and conservative management was chosen. During hospitalization, the patient required transfusion of 16 units of packed red blood cells, 10 units of platelet concentrate, and 20 units of fresh frozen plasma. Gradual mobilization began six days after admission, and the patient was discharged on day 15. The follow-up contrast-enhanced abdominal CT one-month post-injury showed no evidence of pseudoaneurysm, and the renal function remained preserved throughout the course of care.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"71 4","pages":"121-126"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144053967","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}

Male patients diagnosed with urethral stricture between July 2012 and October 2019 who underwent primary treatment by internal urethrotomy or urethral stricture dilatation were divided into two groups : those who received ISD and those who did not. Factors associated with restenosis in the ISD group were also analyzed. The total number of patients analyzed was 45,34 (75.6%) in the ISD group and 11 (24.4%) in the no ISD group. The median age was 71 years. 19 (42.2%) had undergone transurethral surgery, 15 (33.3%) had undergone total prostatectomy, and the majority had undergone urological surgery. The hazard ratio in the ISD group was 0.1894 (95% confidence interval : 0.06749-0.5317, p＝0.001), suggesting that ISD significantly increased the time to recurrence. ISD significantly prolonged the time to recurrence. Also, restenosis was significantly more frequent when ISD was performed for less than 5 months (p＝0.00723). The results suggest that intermittent self-dilation after transurethral surgery as primary treatment for urethral stricture significantly increases the time to restenosis and that performing the procedure for more than 5 months reduces the rate of restenosis development.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"71 4","pages":"105-109"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144050348","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}
