[A Case of Rectum-Infiltrating Prostate Cancer Mimicking Prostate-Infiltrating Rectal Cancer].

A 71-year-old man was admitted to the department of general surgery at our hospital due to constipation. A large bowel endoscopic examination revealed a stenosis of the rectum near the anus. The pathological diagnosis of the biopsy was poorly differentiated adenocarcinoma.

Impact of relative dose intensity in gemcitabine-cisplatin chemotherapy for metastatic urothelial carcinoma.

Objectives: To evaluate the impact of relative dose intensity for gemcitabine-cisplatin chemotherapy in patients with metastatic urothelial carcinoma.

Methods: We retrospectively reviewed the medical records of 18 patients with metastatic urothelial carcinoma, who received gemcitabine-cisplatin regimen as the first-line chemotherapy between 2009 and 2015. The doses of gemcitabine and cisplatin were reduced or the intervals between treatment cycles were prolonged according to the treatment efficacy and adverse events during the first and second cycles.

[A Case of Hemodialysis-Associated Pelvic Amyloidoma Mimicking Renal Cancer-Associated Etiology].

Patients with renal insufficiency receiving long-term hemodialysis often develop so-called hemodialysis amyloidosis characterized by systemic β 2-microglobulin amyloid lesions, while patients with renal cell carcinoma may develop amyloid A(AA) amyloidosis. Herein, we present a 67-year-old man on thirty-yearlong hemodialysis who was diagnosed to have left renal cell carcinoma coincident with a large spaceoccupying lesion adjacent to the psoas muscle in the pelvic cavity. An ultrasound-guided percutaneous needle biopsy was performed at the time of laparoscopic radical nephrectomy.

[Spontaneous Infection of an Atrophic Ureter with an Ectopic Ureteral Opening after Living-Donor Renal Transplantation in a Patient with Kabuki Syndrome].

A 24-year-old woman with a high fever presented at our hospital. She had been diagnosed with Kabuki syndrome at the age of 4 years because she had the typical facial features of the condition ; she had undergone living donor renal transplantation 12 years prior. She was prescribed a course of antibiotics to treat pyelonephritis of the transplanted kidney and the high fever disappeared, but the fever developed again 3 days after the discharge.

[Multi-institute survey on actual conditions of urologic management for severe bladder dysfunction after hysterectomy].

We conducted a multi-institute survey on the conditions related to urologic management of severe voiding dysfunction after hysterectomy for uterine cancer with or without postoperative irradiation. Our first study population was a group of adult female patients currently managed by urologists, using clean intermittent catheterization (CIC). Of the 287 patients in this group, 99 (34%) had suffered from uterine cancer.

Advanced prostate cancer with extremely low prostate-specific antigen value at diagnosis: an example of high dose hook effect.

A 67-year-old man presented with a lower abdominal mass. Radiographic examination revealed a huge mass filling the entire pelvis. Although prostate-specific antigen (PSA) was 1.

A case of lupus cystitis diagnosed from urinary symptoms as the sole initial complaint.

Cystitis related with systemic lupus erythematosis (SLE) is termed as lupus cystitis. It is a subtype of SLE in which gastrointestinal and bladder symptoms are prominent and it usually manifests with other symptoms of SLE. We present a case in a 37-year-old woman whose sole complaint was the severe urinary symptoms.

[A multi-center prospective study for antibiotic prophylaxis to prevent perioperative infections in urologic surgery].

In order to assess the ability of our protocol for antibiotic prophylaxis to prevent perioperative infections in urologic surgery, 1,353 operations of open and laparoscopic urologic surgery conducted in 21 hospitals between September 2002 and August 2003 were subjected to analyses. We classified surgical procedures into four categories by invasiveness and contamination levels: Category A; clean less invasive surgery, Category B; clean invasive or clean-contaminated surgery, Category C; surgery with urinary tract diversion using the intestine. Prophylactic antibiotics were administrated intravenously according to our protocol, such as Category A; first or second generation cephems or penicillins on the operative day only, Category B; first and second generation cephems or penicillins for 3 days, and Category C; first, second or third generation cephems or penicillins for 4 days.

[Testicular cancer with inferior vena caval embolus causing pulmonary embolism following chemotherapy: a case report].

A 21-year-old male presented with right scrotal discomfort. Right high orchiectomy revealed non-seminoma and he was diagnosed with stage I non-seminoma. Since acute myeloid leukemia (AML) was diagnosed incidentally, no adjuvant therapy was given and he received chemotherapy for AML.

[Renal pelvic cancer representing G-CSF production and hypercalcemia simultaneously: a case report].

A 73-year-old man was admitted to the hospital complaining of gross hematuria and left flank pain. Abdominal ultrasonography and computed tomography revealed a left renal tumor with extracapsular extension. Laboratory data showed marked leukocytosis of 121,000/mm3 and hypercalcemia of 12.

[Sarcomatoid carcinoma of the renal pelvis: a case report].

A 65-year-old man visited our hospital with the complaint of left hypochondrial pain. Since he had left giant hydronephrosis due to ureteral stone, we performed left nephrectomy. Unexpectedly, macroscopic examination of the resected kidney revealed multiple yellowish nodules located in the renal pelvis and calyces.
