BackgroundRecently, sarcopenia has been reported as a new predictor for patient outcomes or likelihood of post-operative complications. The purpose of this study was to evaluate the association of the psoas muscle volume with the length of hospitalization among patients undergoing radical cystectomy.MethodsA total of 63 (80.8%) male patients and 15 (19.2%) female patients who underwent radical cystectomy for their bladder cancer in our institution from 2000 to 2015 were analyzed. The psoas muscle index (PMI) was calculated by normalizing the psoas muscle area calculated using axial computed tomography at the level of the umbilicus (cm2) by the square of the body height (m2). Longer hospitalization was defined as hospitalization exceeding 30 days after surgery.ResultsThe median PMIs (mean ± standard deviation) were 391 (394 ± 92.1) and 271 (278 ± 92.6) cm2/m2 in men and women, respectively. Thus, the PMIs of male patients were significantly larger than those of females (p < 0.001). Based on the differences in gender, we analyzed 63 male patients for a further analysis. In male patients, those hospitalized longer showed a significantly smaller PMI than those normally discharged (377 ± 93.1 vs. 425 ± 83.4; p = 0.04). Similarly, male patients with a small PMI (<400) had a significantly worse overall survival (p = 0.02) than those with a large PMI (≥400).ConclusionsThe presence of sarcopenia was found to be associated with significantly longer hospitalization after radical cystectomy in male patients. Furthermore, in men, a PMI <400 may suggest a significantly worse prognosis.

HighlightsWe experienced the foreign body had become severely calcified.The foreign bogy was successfully removed by bladder wall incision.The foreign body was covered by labor.

BackgroundMost patients with testicular cancer are infertile; thus, the preservation of the sperm after surgery is an important factor to consider. We report two cases of bilateral testicular cancer in patients who underwent bilateral higher orchiectomy and simultaneous testicular sperm extraction.Case presentationTwo Asian-Japanese men were referred to our hospital with bilateral testicular tumors. Both of the patients were preoperatively diagnosed with azoospermia and requested testicular sperm extraction at the time of higher orchiectomy. In one patient, sperm was successfully harvested and then frozen. In the other patient, sperm could not be retrieved from the patient’s testis. In both patients, the pathological diagnosis was seminoma. Testicular tumors often occur in patients of reproductive age. The preservation of sperm before chemotherapy or bilateral orchiectomy is necessary for patients with testicular tumors who wish to be fathers.ConclusionsOnco-testicular sperm extraction might be an option for patients with testicular cancer and azoospermia or severe oligospermia.

International Journal of Case Reports and Images (IJCRI) is an international, peer reviewed, monthly, open access, online journal, publishing high-quality, articles in all areas of basic medical sciences and clinical specialties.Aim of IJCRI is to encourage the publication of new information by providing a platform for reporting of unique, unusual and rare cases which enhance understanding of disease process, its diagnosis, management and clinico-pathologic correlations.IJCRI publishes Review Articles, Case Series, Case Reports, Case in Images, Clinical Images and Letters to Editor.

Castleman’s disease was first reported in 1954 by Castleman et al. and identified as an uncommon lymphoproliferative disorder. In most cases, Castleman’s diseases are detected in the chest, head, and neck. A 71-year-old man was referred to our hospital due to a retroperitoneal tumor in the para-aortic area by computed tomography (CT). Positron emission tomography-CT revealed an uptake in this tumor, suggesting malignant diseases. Laparoscopic tumorectomy was performed, and the pathological diagnosis was Castleman’s disease, hyaline vascular type. No evidence of recurrence was observed 20 months after surgery. We herein report a rare case of retroperitoneal Castleman’s disease.
