We report a case in a 51-year-old woman with diabetic nephropathy who underwent an ABO-compatible living-donor kidney transplant from her younger brother. Although the procedure was completed without major complications, the patient developed persistent oliguria postoperatively. Serial allograft biopsies on postoperative days 1, 3, and 13 consistently showed findings of ATN without evidence of acute rejection or calcineurin inhibitor toxicity. Imaging studies revealed no vascular abnormalities or urinary tract obstruction. Despite adequate fluid management and stable hemodynamics, urine output remained below 500 ml/day for 26 days, and dialysis was required. On postoperative day 27, urine output gradually increased, allowing for withdrawal from dialysis by day 29. The patient was discharged on postoperative day 44, and renal function remained stable with a serum creatinine of 1.0 mg/dl at 9 months post-transplant. Intraoperative review of the donor nephrectomy video revealed purplish discoloration of the graft surface, raising suspicion of transient ischemia potentially caused by venous congestion during renal mobilization. This case emphasizes the importance of gentle vascular handling during donor nephrectomy and vigilant postoperative monitoring. Even in cases of prolonged DGF, recovery may be achieved with continued supportive therapy and repeated biopsies to rule out rejection. This report highlights that timely diagnosis and conservative management can lead to successful graft recovery, even after extended periods of oliguria.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"72 9","pages":"283-289"},"PeriodicalIF":0.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149116070","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}

Three months after the treatment, the efficacy of this drugs was assessed based on any improvement in subjective symptoms by the medical interview as follows ;\"ineffective\", \"slightly effective\", \"moderately effective\", and\"excellently effective\". Desire to continue this drug, the duration of continuation, and adverse effects were investigated. The cases in which efficacy was\"slightly effective\"or better were defined as the responder group, and patients'characteristics were compared between the responder and non-responder groups. The mean age was 72.2 years, and the mean period from the start of ADT to keishibukuryogan administration was 14.5 months. The efficacy of this drug was excellent in 3 cases, moderately effective in 11, slightly effective in 36, and ineffective in 52. Fifty-six patients desired to continue the treatment after three months. The average duration of drug continuation in the responder group was 13.7 months. In the responder group, the cases with a history of radiation therapy were significantly frequent (p＝0.0277). Six patients discontinued the drug administration due to adverse effects, with 3 experiencing itching, and 1 each experiencing loose stools, nightmares, and difficulty taking the drug.

Pathological examination revealed xanthogranulomatous endometritis, which was considered the source of the mesh infection. The patient was discharged on postoperative day 7 without complications. In early January year X＋1, she developed buttock pain that persisted for approximately 2 weeks without improvement, prompting her to return to our hospital. Magnetic resonance imaging findings indicated pyogenic spondylitis. She was admitted and treated with intravenous sulbactam/ampicillin for 1 week, but her symptoms did not improve. Laparoscopic mesh removal was subsequently performed. After surgery, the antibiotic regimen was switched to intravenous imipenem/cilastatin, resulting in good infection control. However, progressive bone destruction was noted, and on postoperative day 37, posterior spinal fusion from L3 to the pelvis was performed by our orthopedic team. The postoperative course following spinal surgery was favorable, with marked symptom relief. Oral minocycline was initiated on postoperative day 69 and continued until day 133. The patient was discharged ambulatorily on postoperative day 139.

Furthermore, the General Rule stated that\"it is generally understood that pathological findings from biopsies are not taken into consideration when determining T categories\". We investigated how physicians interpret the General Rule and perform T classification in real-world clinical practice. We prepared five hypothetical cases with negative digital rectal examination findings but with lesions identified on magnetic resonance imaging (MRI) and conducted a questionnaire survey targeting board-certified urologists certified by the Japanese Urological Association. We received responses from 58 participants. Twenty-six participants (44.8%) diagnosed cases with discontinuous lesions in both lobes as cT2a, and 32 participants (55.2%) diagnosed them as cT2c. In addition, 41 participants (70.7%) diagnosed cases in which lesions were found in one lobe on MRI and cancer was detected in both lobes by biopsies as cT2a, while 17 participants (29.3%) diagnosed them as cT2c. Furthermore, three participants (5.2%) diagnosed cases in which cancer was detected by biopsies only from the contralateral side where lesions were found on MRI as cT1c, 49 participants (84.5%) diagnosed them as cT2a, and six participants (10.3%) diagnosed them as cT2c. In staging prostate cancer, the General Rule can have multiple meanings and there are cases in which even specialists disagree.

A 63-year-old woman presented with fever and right flank pain. Computed tomography revealed right hydronephrosis, a renal pelvic mass, and para-aortic lymphadenopathy. Selective urinary cytology was negative, and ureteroscopic examination showed no visible tumor. Because of recurrent febrile urinary tract infections, retroperitoneal laparoscopic right nephrectomy was performed. The resected specimen showed mucosal thickening and a mass lesion in the renal pelvis. Histopathological examination demonstrated diffuse proliferation of atypical lymphoid cells positive for CD20 and CD79a, consistent with diffuse large B-cell lymphoma (DLBCL). The patient received eight cycles of R-THP-COP (rituximab, pirarubicin, cyclophosphamide, vincristine and prednisolone) chemotherapy, and para-aortic lymphadenopathy regressed. She remains in complete remission 60 months after surgery. As imaging findings are nonspecific and urinary cytology is usually negative, preoperative diagnosis of renal pelvic lymphoma is challenging.
