Safety and efficacy of various strains of bacille Calmette-Guérin in the treatment of bladder tumours in standard clinical practice.

Background: The natural progression of bladder tumours (nonmuscle-invasive bladder cancer [NMIBC]) is recurrence with a high rate of progression. Bacille Calmette-Guérin (BCG) has been shown effective in reducing these rates, but there are few comparative studies between strains.

Material And Methods: An observational, prospective and multicentre registry studied 433 patients with a 12-month follow-up visit from 961 registered patients, assessing disease-free survival (DFS), progression-free survival (PFS) cancer-specific survival (CSS) and adverse effects.

Small-calibre percutaneous nephrolithotomy (SC-PCNL). Therapeutic decision algorithm.

Introduction: The progressive reduction in the calibre of the tract in percutaneous kidney surgery to the point of miniaturisation has expanded its use to smaller stones that until now have been treated with extracorporeal shock wave lithotripsy (ESWL) and retrograde intrarenal surgery (RIRS).

Objective: To provide an update on the various techniques of small-calibre nephrolithotomy (SC-PCNL) analyse their efficacy, safety and indications and determine their degree of implantation at this time.

Material And Methods: We performed a review in PubMed of Spanish and English medical literature on the various techniques of SC-PCNL.

Predicting results of daily-practice cystoscopies.

Objective: Our objective was to elaborate a predictive model of bladder cancer, in an unselected clinical population submitted to cystoscopy.

Materials And Methods: We recruited consecutive patients that underwent cystoscopy due to suspicion of bladder cancer or surveillance of a previously diagnosed bladder cancer. Urine cytology and a BTA-stat® (BTA) test were carried out for all patients.

[Fibromyxoid sarcoma of kidney].

Objective: To report a case of fibromyxoid sarcoma of the kidney.

Clinic Report: A 28-year-old male patient attended the urological outpatient clinic for left varicocele associated with abdominal pain, fatigue, and weight loss.

Conclusions: Low-grade fibromyxoid sarcoma of the kidney is an uncommon tumor.

[Long-term follow-up of antegrade endopyelotomy. Factors that influence the outcome].

Objective: To find out the outcomes of endopyelotomy alter a long-term follow-up and determine the variables that may influence the results.

Material And Methods: We review the results obtained in 77 patients that underwent antegrade endopyelotomy with ureteropelvic junction obstruction, after 10-year follow-up. We used the Kaplan-Meier curve in order to determine the probable failure rate at a certain point.
