The patient reported a swelling in his left lower abdomen over the past 6 months. Magnetic resonance imaging revealed a left inguinal mass extending from the left spermatic cord to the left inguinal(More)
To develop a new method of detecting cellular injury caused by oxygen radicals, we studied endogenous fluorescence from the cultured cells of a rat gastric mucosal epithelial cell line. Measurement with an ultra-high sensitivity camera-image processor system under an inverted epifluorescence microscope showed that the fluorescence intensity of the cells(More)
Autofluorescence observations enable scientists to sensitively identify various lesions. Non-steroidal anti-inflammatory drugs such as aspirin and indomethacin are well known to induce gastric mucosal injuries. Our purpose was to clarify whether the observation of mucosal autofluorescence could help us to recognize indomethacin-induced gastric lesion(More)
We report a case of traumatic unilateral renal artery thrombosis that was successfully treated by thrombolytic therapy. The patient was a 17-year-old woman, who had put her left upper abdomen between a wall and the handle of a ground roller when using it. A computed tomography scan with intravenous contrast showed a lack of contrast in the left kidney.(More)
A 22-year-old man consulted our hospital with a left intrascrotal mass and a six-day history of dull pain in the left lower abdomen. Serum levels of tumor markers were normal. Testicular ultrasonography demonstrated a heterogeneous isoechoic mass in the left testis. Computed tomography revealed a left testicular mass with high density. A diagnosis of(More)
Intraurethral catheters are effective in the treatment of elderly patients with benign prostate hyperplasia (BPH) who have severe complications. However, it is not easy to measure the length of the prostatic urethra and to determine an appropriate location for the urethral catheter using only fluoroscopy, especially in patient with severe mid-lobe(More)
BACKGROUND Occasionally, difficulty with standard urethral catheterization is encountered. OBJECTIVE We conducted a pilot study to evaluate whether transabdominal ultrasound (TAUS) showed the tip of a urethral catheter and whether TAUS-guided catheterization with transrectal pressure is successful in male patients in whom performing standard(More)
An 82-year-old man who was receiving treatment for prostate cancer and cholangiocellular carcinoma was admitted to our hospital because of chest discomfort and dyspnea. At the time of admission, 16 months after the start of hormone therapy, the prostate-specific antigen level was 454.08 ng/ml. Chest radiography revealed cardiomegaly, and ultrasonography(More)
We report a case of urinary retention caused by true phimosis in a 67-year-old man with untreated diabetes mellitus. The patient could not void in a stream, and urine dropped out of the external urethral orifice with manual compression of the penis. Subsequently, he visited our hospital due to urinary retention. Ultrasonography revealed right hydronephrosis(More)
