[An Increase in Cases of Bladder Tamponade Due to Cystitis Among Elderly Women and Clinical Background Factors].

Bladder tamponade is thought to be caused mainly by bladder cancer or radiation cystitis. However, in women, it may often be caused by cystitis in clinical settings. This has not been noted in previous reports of bladder tamponade in Japan.

[Cholesterol crystal embolization following urinary diversion: a case report].

Cholesterol crystal embolization (CCE) is a cardiovascular disorder with poor prognosis, causing multiple organ failure. The primary pathological condition of the disease is embolization of cholesterol crystals in peripheral vessels. We report a case of CCE following urinary diversion.

Antimicrobial prophylaxis to prevent perioperative infection in urological surgery: a multicenter study.

We prospectively investigated the rates of incidence of surgical site infection (SSI), urinary tract infection (UTI), and remote infection (RI) in 4,677 patients who underwent urological surgery from January to December 2010, including 2,507 endourological cases, 1,276 clean cases, 807 clean-contaminated cases, and 87 contaminated cases involving bowel segments. A single dose of antimicrobial prophylaxis (AMP) was administered in the endourological, clean, and clean-contaminated surgery cases, except for patients who underwent transurethral resection of the prostate (TURP) or percutaneous nephrolithotripsy (PNL). AMP was administered within 72 h in TURP and PNL, and AMP was administered within 48 h in contaminated surgery cases.

[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.

[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.

Leiomyosarcoma of the spermatic cord: a case report.

A 61-year-old man presented to our hospital with a 1.5-year history of a gradually enlarging mass in the left scrotum. The mass was apart from the testis and fixed to the spermatic cord.

[Superselective endovascular treatment of renal artery aneurysms with detachable microcoils].

Selective transcatheter embolization using an interlocking detachable coil was performed in two cases with renal artery aneurysms. Case 1, a 73-year-old male, was referred to our department complaining of macrohematuria persisting for three days. Case 2, a 52-year-old female, visited our department because calcifications in both renal pedicle areas were found in a health check up.

Predicting disease outcome of non-invasive transitional cell carcinoma of the urinary bladder using an artificial neural network model: results of patient follow-up for 15 years or longer.

Background: Patients with non-invasive (Ta/T1) transitional cell carcinoma (TCC) of the urinary bladder are often observed without progression in the long-term follow-up period, although many of them experience recurrence of disease. It is difficult to accurately predict the disease outcome of each patient with Ta/T1 TCC using conventional prognostic criteria. In this study, we examined the usefulness of artificial neural networks (ANNs) to predict the long-term disease outcome of patients with TCC of the urinary bladder.
