[Upper urinary tract tumors: our experience].

Objectives: To study the clinical, diagnostic, and therapeutic features of upper urinary tract tumors.

Methods: We perform a retrospective study of upper urinary tract tumors treated in our Department at Clinica La Luz Madrid between 1995 and 2008.

Results: We treated 42 tumors in 40 patients.

[Hydraulic dilation (URETEROMAT): effective and safe ureteroscopy].

Objectives: After the description and standardization of the technique of ureteroscopy in 1979, several methods to obtain a nontraumatic, simple, efficient and fast ureteral access have been developed. The hydraulic expansion of the ureter was possible in 1986, with the development of ureteromat. We evaluate the effectiveness of hydraulic ureteral expansion (Ureteromat) for ureteral access and the later endoscopic procedures.

[MRI-spectroscopy-guided prostate biopsy].

Prostate cancer is currently one of the main causes of urological practice workload. Patients with negative prostate biopsies may pose serious problems to the urologist in the decision making process for follow-up due to the lack of definitive data in the follow-up algorithm. MRI spectroscopy seems to open a diagnostic window evaluating prostatic metabolic changes.

[Anterograde endopyelotomy].

Objective: To analyze the results obtained with antegrade endopyelotomy and compare them with those reported in the literature.

Methods: 16 patients with ureteropelvic junction (UPJ) obstruction treated by antegrade endopyelotomy were evaluated.

Results: In our series the success rate was 81.
