Purpose: Nitazoxanide (NTZ) has shown a promising antitumoral effect, the current study compared the anti-neoplastic effects of intravesical NTZ and BCG plus NTZ in NMIBC animal model.
Methods: 30 rats, Fisher 344 were instilled with 4 intravesical doses of 1.5 mg/kg of N-methyl-N-nitrosourea (MNU) every 15 days for BC induction.
Purpose: To better understand potential modifiable risk factors guiding preventive interventions against lower urinary tract symptoms (LUTS).
Methods: A prospective cross-sectional study, including healthy men aged 40-70 years under routine urological evaluation, measured the strength of association between the International Prostate Symptom Score (IPSS) and socio-demographic, lifestyle, and health-related factors using logistic and linear regression adjusted for confounding factors. Men with urethral or prostate surgery were excluded.
Purpose: To subjectively and objectively compare an accessible interactive electronic library using Moodle with lectures for urology teaching of medical students.
Methods: Forty consecutive fourth-year medical students and one urology teacher were exposed to two teaching methods (4 weeks each) in the form of problem-based learning: - lectures and - student-centered group discussion based on Moodle (modular object-oriented dynamic learning environment) full time online delivered (24/7) with video surgeries, electronic urology cases and additional basic principles of the disease process.
Results: All 40 students completed the study.
Purpose: After a successful pyeloplasty at 3 to 6 months, the question remains whether children need a long follow-up.
Methods: The medical charts of patients with long-term follow-up (> 5 years), who underwent dismembered pyeloplasty for uretero-pelvic junction obstruction (UPJO) from May 1998 to May 2007, excluding those with bilateral UPJO, solitary kidney, associated vesicoureteral reflux or other abnormalities, and inconclusive renogram due to poor renal function, were retrospectively reviewed. Ultrasonography, differential renal function (DRF, DMSA), and renal drainage on diuretic renography (diethylene-triamine-pentaacetate technetium-99 or DTPA-Tc99) were performed at 3 and 6 months every year.
Objective: To verify and compare the results of behavioral modification plus pelvic floor muscle training and behavioral modifications plus oxybutynin chloride in children with nonmonosymptomatic enuresis.
Methods: A total of 47 children were randomized using opaque and sealed envelopes sequentially numbered. Group I was composed of 21 children who underwent antimuscarinic treatment (oxybutynin), and Group II was composed of 26 patients who underwent pelvic floor muscle training.
A 78-year-old man with coagulopathy and lower urinary tract symptoms secondary to benign prostatic hyperplasia underwent transurethral prostate ethanol gel injection. Six months after the injection, the patient presented with irritative symptoms and hematuria. Ultrasonography revealed a 5-cm intravesical calculus.

Methods: Between January 1995 and December 2000, the records of 119 patients with staghorn calculi who underwent percutaneous nephrolithotomy were retrospectively reviewed. The mean stone burden was 6.
