The resulting posterior displacement of the ureter may produce compression, impaired urinary drainage, and hydronephrosis.Case presentation: A 35-year-old man was referred following the detection of a right-sided Type I retrocaval ureter during evaluation of right renal colic. Laboratory investigations and physical examination were unremarkable. Computed tomography urography and retrograde pyelography demonstrated the characteristic abnormal ureteral course with associated proximal obstruction. The patient underwent laparoscopic retroperitoneal mobilization, transposition, and reconstruction of the ureter. The operative steps are presented in an accompanying video. Recovery was uncomplicated, and follow-up imaging demonstrated resolution of the obstruction.Conclusion: Laparoscopic retroperitoneal reconstruction provides direct access to the affected ureter while avoiding entry into the peritoneal cavity. In appropriately selected patients and experienced hands, it represents an effective minimally invasive option for the treatment of retrocaval ureter.","PeriodicalId":30323,"journal":{"name":"Case Reports in Urology","volume":"2026 ","pages":"8373968"},"PeriodicalIF":0.0,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13528853/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148867021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although radiotherapy has traditionally raised concern as a risk factor for fistulization, this case suggests that selected patients with a pre-existing perianal fistula may be treated with careful multidisciplinary planning and modern radiotherapy techniques.Case presentation: A 70-year-old male diagnosed with favorable intermediate-risk prostate cancer and a concurrent perianal fistula was treated with definitive radiation therapy and staged surgical treatment, respectively. The patient underwent intensity-modulated radiation therapy (IMRT) with daily image-guided radiation therapy (IGRT), receiving a total dose of 70 Gy in 28 fractions while minimizing radiation dose to the perianal region. Prior to radiation, a seton was placed to facilitate drainage and reduce infection risk from the fistula. Following radiotherapy, the patient underwent successful surgical fistulectomy without complications. At 26 months posttreatment, the patient remains free of biochemical recurrence and without recurrence of the perianal fistula.Conclusions: This case highlights the clinical importance of applying and coordinating established management principles to an uncommon and challenging scenario. Although seton placement, IMRT/IGRT, and fistula surgery are individually well-established approaches, their sequencing in the setting of localized prostate cancer with a concurrent pre-existing perianal fistula remains poorly described. This report offers a practical example of individualized, staged management in a complex clinical scenario for which standardized treatment pathways remain limited.","PeriodicalId":30323,"journal":{"name":"Case Reports in Urology","volume":"2026 ","pages":"9964573"},"PeriodicalIF":0.0,"publicationDate":"2026-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13498855/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148798816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ureteric obstruction by this subtype of lymphoma can mimic other more common genitourinary or retroperitoneal conditions. The current case describes a 42-year-old female who presented with abdominal pain and hydronephrosis without findings supportive of renal or ureteric calculus. Diagnostic work-up was unremarkable, even with the employment of endoscopic evaluation. The patient's ureter was dilated and she underwent both stenting and eventual percutaneous nephrostomy tube placement. Ultimately, she underwent surgical intervention with ureteral reimplantation and associated histopathological analysis was able to definitively diagnose a low-grade B-cell extranodal marginal zone lymphoma. The present case highlights the diagnostic challenges associated with this rare etiology of urinary obstruction. It also emphasizes the importance of considering atypical malignancy in the differential diagnosis of recurrent ureteral obstruction, especially when traditional radiological imaging and clinical assessment are unrevealing.","PeriodicalId":30323,"journal":{"name":"Case Reports in Urology","volume":"2026 ","pages":"1563744"},"PeriodicalIF":0.0,"publicationDate":"2026-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13498890/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148798814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
