Although the intermittent balloon catheter has the potential to improve the patient's quality of life (QOL), appropriate information and guidelines are needed to prevent complications such as hematuria and urinary tract infection. This study aimed to assess the real-world practice, complications, and problems associated with the use of intermittent balloon catheters and provide useful information for future medical care. We conducted a questionnaire survey on patients with spinal cord lesions who currently use or have used intermittent balloon catheters in the past. Seventy-six patients with spinal cord lesions who visited Kanagawa Rehabilitation Hospital from August 2020 to March 2021 and gave consent for participating in this study were included. QOL scores before and after intermittent balloon catheter use showed significant improvement after use. Forty-six of the 76 (61.3%) patients had complications. Overall complications were significantly associated with male sex and possibly linked to non-traumatic spinal cord lesions.","PeriodicalId":39291,"journal":{"name":"Acta Urologica Japonica","volume":"70 5","pages":"111-115"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141535631","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}

We report a case of SCCB that was refractory to multiple chemotherapies but responded to pembrolizumab. A 77-year-old male, diagnosed with clinical stage T3N0M0 small cell carcinoma and invasive urothelial carcinoma by transurethral resection of bladder tumor (TURBT), underwent robot-assisted radical cystectomy after three cycles of neoadjuvant cisplatin-irinotecan chemotherapy, and pathological examination revealed only small cell carcinoma in his cystectomy specimen. After three courses of adjuvant carboplatin-etoposide chemotherapy, the patient developed liver and bone metastases. Furthermore, after two courses of amrubicin, we started pembrolizumab due to the progression of metastases. Metastases decreased after starting pembrolizumab and continued to decrease after discontinuation because of immunerelated adverse events (irAEs).

Incidental prostate carcinoma (iPCa) following HoLEP occurs at a certain rate. Predictors, include age, biopsy, history, preoperative prostate specific antigen, and prostate volume. We compared cases with and without incidental carcinoma detection among 257 patients with BPH who underwent HoLEP at our hospital from July 2015 to December 2022. Among the 257 patients, 29 (11.3%) were found to have incidental carcinoma. Although 1 patient switched to endocrine therapy the remaining patients showed good prognosis under surveillance therapy. The proportion of cases with magnetic resonance imaging (MRI) findings suggestive of carcinoma was significantly higher in the incidental carcinoma detection group (p＝0.009). Furthermore, univariate analysis of incidental carcinoma predictive factors revealed a significant difference in MRI findings (odds ratio [OR] 2.92 ; confidence interval [CI] 1.33-6.42), and multivariate analysis showed similar results (OR 2.92 ; CI 1.33-6.42).

There was no dysplasia in the bladder epithelium. Therefore, we diagnosed the case as bladder amyloidosis. Immunostaining of the amyloid subtype revealed transthyretin amyloid (ATTR) amyloidosis. Bence-Jones protein in urine was negative, M protein was not detected in serum protein electrophoresis, and serum amyloid A was at the threshold. Scintigraphy for 99m Tc pyrophosphoric acid was positive in the myocardium. No genetic disorder was detected. We concluded that it was systemic ATTRwt amyloidosis as above. The patient did not wish to be treated for the systemic amyloidosis. Thirteen months after surgery, the patient showed no signs of recurrence in the bladder.

Nineteen years later (age＝60), he was diagnosed with right testicular tumor and underwent right orchiectomy. Herein, the pathological finding showed seminoma (stage IA). The patient in case 3 had a history of right orchiectomy for testicular tumor at the age of 25.

Fourteen years later (age＝39), he was diagnosed with left testicular tumor and underwent left orchiectomy. The pathological finding revealed seminoma (stage IB).

Due to the long interval between the occurrence of bilateral metachronous testicular tumors (mean＝19 years ; three cases), long-term observation is necessary to detect the possible occurrence of contralateral testicular tumors.
