Ureter tumor thrombus (TT) of renal cell carcinoma (RCC) is quite rare, although RCC-TT in the inferior vena cava (IVC) is not uncommon. We report the first case of RCC-TT extending into the IVC and ovarian vein as well as the ureter. Neoadjuvant axitinib shrank both the primary tumor and TT, making radical nephrectomy less invasive, particularly by(More)
Endocrine resistance is a major problem in prostate cancer. Recent studies suggest that cellular plasticity plays a key role in therapy resistance. Yet little is known about the cellular changes of human prostate cancer after androgen deprivation therapy (ADT). In this study, we investigated cellular senescence, senescence-associated secretory phenotypes(More)
Urethral perforation due to a foreign body self-inserted into the urethra is quite rare, although such foreign bodies themselves are not uncommon in clinical urologic practice. Two cases of a self-inserted urethral foreign body leading to anterior urethral perforation have been reported in the English-language literature. However, there are no case reports(More)
Transverse testicular ectopia (TTE) is a rare congenital anomaly in which both testes migrate toward the same hemiscrotum. We present a case of TTE in a 33-year-old man. Laparoscopy showed the left spermatic vessels, accompanied by parietal peritoneum, which formed a septum that divided the pelvic space into two, were extending transversely from the left(More)
epididymal tubule (Figure 1c) was harvested simply by touching the base of sterilized disposable plastic dishes (60 mm in diameter), directly to the incised epididymal tubule (Figure 1d). The epididymal fluid collected in the plastic dishes was diluted with washing medium and then examined for the presence of sperm directly under an inverted phase-contrast(More)
