Beginning in May 2016, an 83-year-old male underwent three transurethral resections for recurrent bladder cancer. In June 2017, following a positive urine cytology exam, a random biopsy of the bladder was performed. The histopathological findings revealed urothelial carcinoma, high grade, pTis. Treatment consisted of bacillus Calmette-Guerin (BCG) instillation. In February 2018, he complained of left scrotal swelling and pain ; and, was diagnosed with left epididymitis. However, based on resistance to the antibiotic agent, epididymal tuberculosis after BCG therapy was suspected and resection of the left testis and epididymis was performed. Histopathological findings revealed epididymal tuberculosis. Three months after the left orchiectomy, the patient complained of right scrotal swelling and pain. Based on antibiotic resistance and the positive findings of a urinary mycobacterium tuberculosis polymerase chain reaction assay, metachronous right epididymal tuberculosis was suspected and the patient underwent resection of the right epididymis. While the histopathological findings did not indicate tuberculosis, the urinary mycobacterium culture was positive. The patient was diagnosed with right epididymal tuberculosis and after surgery was administered an antituberculosis drug.A 39-year-old man experiencing cranial nerve symptoms was referred to our neurosurgery department after a brain tumor was detected on computed tomography (CT) scans at a local hospital. Due to convulsive symptoms, the patient was admitted to our hospital for detailed examination. The patient was diagnosed with right testicular tumor, multiple brain metastases, multiple lung metastases and right kidney metastases, and was transferred to our urology department. Since the testicular tumor was staged as IIIC and identified as poor prognosis by the International Germ Cell Consensus classification (IGCCC), Bleomycin Etoposide Cisplatin (BEP) chemotherapy was initiated prior to surgery. A right high orchiectomy was performed after two courses of BEP chemotherapy. https://www.selleckchem.com/products/ly3522348.html Histopathology revealed mixed germ cell tumors (seminoma and/or embryonal carcinoma+teratoma) along with the following results ly (-) ; Intratubular Malignant Germ Cells (ITMGC) (+, viable) ; tunica albuginea invasion (-) ; spermatic cord invasion (-) ; tumor size (73× 50×45 mm). Two additional courses of BEP chemotherapy and two courses of Paclitaxel Ifomaide Cisplatin(TIP) chemotherapy were performed successively. The CT revealed metastatic lesions shrinking steadily but the metastatic foci still remained. Since tumor markers were not negative, continuous chemotherapy was considered. However, strong side effects were expected, and treatment was discontinued. Since then,the tumors continued to shrink, and the tumor markers became negative. Currently, the patient maintains complete response and is being followed-up.This case report documents seminal vesicle cystadenoma with concurrent prostate cancer in a 49-yearold man evaluated at follow-up for a high prostate-specific antigen level (12 ng/ml). Transrectal ultrasound-guided prostate biopsy was performed for adenocarcinoma of the prostate (Gleason score 3+4= 7). Staging computed tomography showed a 6.6×5.5×5.0 cm cystic tumorof the seminal vesicle. A possible diagnosis of primary malignant tumor of the seminal vesicle with concurrent organ-confined prostate cancer was considered. However, seminal vesicle tumor biopsy was not performed because the patient underwent open radical prostatectomy with the resection of the seminal vesicle tumor. Histopathologic examination of the seminal vesicle and the prostate revealed cystadenoma (Gleason score 4+3=7) and adenocarcinoma (stage pT2cN0). Neither recurrence of the cystadenoma nor biochemical recurrence of the prostate cancer was observed 5 years and 6 months after the surgery.A 26-year-old man visited our hospital with a complaint of macrohematuria. Cystoscopy revealed a nodular tumor around the right ureteral orifice. Transurethral resection of bladder tumor was performed, and the tumor was pathologically diagnosed as the nested variant of urothelial carcinoma (NVUC). Radical cystectomy and modified Studer orthotopic neobladder reconstruction were performed. The pathological stage was pT2a, pN2. The patient received 2 courses of adjuvant chemotherapy consisting of gemcitabine and cisplatin. The patient is currently free from disease at 31 months after the treatment. To our knowledge, this case report represents the youngest case of NVUC.A 27-year-old man was referred to our hospital with right-sided back pain and renal dysfunction. Computed tomography revealed a right-sided horseshoe kidney with hydronephrosis and a thin renal cortex. Diuretic renography revealed a nonfunctioning right kidney. We diagnosed the patient with a symptomatic nonfunctioning right kidney and performed laparoscopic right heminephrectomy. His right-sided back pain reduced postoperatively ; however, he developed retrograde ejaculation, which was attributable to intraoperative injury to the superior hypogastric nerve plexus. We treated the patient with amoxapine (an antidepressant), which led to improvement in retrograde ejaculation.Radical prostatectomy is one of the major treatment options for patients with localized prostate cancer, and biochemical recurrence (BCR) after surgery is regarded as one of the representative indicators of the oncological outcome. The positive surgical margin (PSM) of the surgical specimen is considered to be one of the risk factors for BCR and its length (LPSM) was reported to be positively correlated with the risk for BCR. We retrospectively investigated the relationship between BCR and LPSM in 115 patients who underwent radical retropubic prostatectomy or laparoscopic radical prostatectomy without neoadjuvant hormone therapy at Shimada Municipal Hospital between 2008 and 2016. We found that the patients with a LPSM of 3 mm or longer had a higher risk for BCR than those with a LPSM shorter than 3 mm (HR 10.98, 95% confidence interval 3.09-39.06, p less then 0.001), and patients with pT3 disease with a LPSM of 3 mm or longer had a higher risk for early BCR. Therefore, the LPSM may be a useful parameter to predict BCR after radical prostatectomy.
