Influence of double J stent in the complications of ureterovesical anastomosis during kidney transplantation.

Introduction: Complications arising from ureterovesical anastomosis in kidney transplantation have an important influence on the success of the procedure.

The aim of this study is to analyze, within our department, the implementation of a laparoscopic radical cystectomy (LRC) program compared with a well consolidated and standardized open radical cystectomy (ORC) program.

Post-surgical complications in patients with bladder cancer treated with cystectomy: Differences between open and laparoscopic approach.

Objectives: The main objective of this study is to establish the role of minimally invasive surgery, laparoscopic radical cystectomy, versus open surgery by analyzing their perioperative complications.

Influence of laparoscopic access in cancer-specific mortality of patients with pTa-2pN0R0 bladder cancer treated with radical cistectomy.

However, its effect on the oncological results is still controversial due to the lack of definite analyses. The objective of this study is to evaluate the effect of the laparoscopic approach on cancer-specific mortality.

[Conservative treatment of renal cancer using HIFU. Procedure, indications, and results].

This article reviews the mechanisms of action of high-intensity focused ultrasound (HIFU), as well as both experimental and clinical work related to renal tumor treatment. While most currently available experience in urological tumors with HIFU has been obtained with prostate cancer, an increasing number of studies support the efficacy and safety of this procedure for renal tumor destruction. HIFU completes, with cryotherapy and radiofrequency, the spectrum of minimally invasive surgery in renal cancer, intended to decrease surgical morbidity while achieving similar oncological control rates.

[Upper urinary tract tumor: differential diagnosis by radiological images].

To perform the adequate treatment of upper urinary tract lesions it is very important to have an exact diagnosis. When the suspicion of an upper tract urothelial tumor is established the initial evaluation is carried out by imaging diagnostic tests (intravenous urography, pyelography, and others). The association of radiological tests and urine cytologies allows us to get to a correct diagnosis in most cases.
