[Evaluation of our series of first biopsies and rebiopsies by applying a prostate cancer risk calculator.].

Objectives: 1.- To know the risk of detectable Prostate Cancer (PC) and significant PC by applying a Risk Calculator to patients who underwent a prostate biopsy (PB) and to analyze if there are significant differences between the risk of patients who had positive versus negative biopsies. 2.

[First prostate biopsy vs rebiopsy: Analysis of our series.].

Introduction: Prostate re-biopsydoes not guarantee detection of prostate cancer(PC), sometimes leading to overdiagnosis of clinicallyinsignificant tumors. The present study shows theincidence of PC in our hospital and analyzes thedistribution of risk groups and prognosis depending inthe diagnosis obtained by first biopsy vs rebiopsy.

Objectives: 1.

Vascular abnormalities in horseshoe kidney.

50 year old male with history of renal colic presenting to the emergency room with left colic pain. On ultrasound horseshoe kidneys were visualized without hydronephrosis or stones. CT scan: horseshoe kidney with inferior isthmus, no signs of nephrolithiasis or urolithiasis.

Antopol-Goldman lesion: a rare clinical entity in the differential diagnosis of macroscopic hematuria.

Objective: To describe the case of a patient with gross hematuria. The pathological study revealed a subepithelial hematoma of the renal pelvis (Antopol-Goldman lesion).

Methods/results: An 86 year-old woman presented with gross hematuria through the right ureteral orifice.

[Malacoplakia of the testis: a new case report and a literature review].

Malakoplakia is a uncommon chronic granulomatous condition of a benign nature preferentially occurring in the genitourinary tract. Testes are affected in 12% of cases, and the first case of testicular malakoplakia was reported in 1958. Forty cases have been reported worldwide since that date.

[Correlation between Gleason score on prostate biopsies diagnostic of adenocarcinoma and radical prostatectomy specimens].

Objectives: We analyse the concordance between Gleason scores on prostate biopsies diagnostic of adenocarcinoma and radical prostatectomy specimens.

Methods: We reviewed the charts of 214 patients who underwent radical prostatectomy between January 1992 and November 2002. We calculated the percentage of correct diagnosis, understaging and overstaging for individual Gleason and for groups with scores between 2-4, 5-6, 7 and 8-10.

[Collecting duct (Bellini) carcinoma].

Objectives: To report one case of collecting duct (Bellini) carcinoma and to review the national bibliography. To analyze the clinical, diagnostic, and therapeutic features of this malignant renal tumor.

Methods/results: A 36-year-old male presenting with monosymptomatic hematuria and clot retention was diagnosed of left renal mass suggestive of renal carcinoma.

[Renal artery embolism].

Objectives: To report a case of renal artery embolism. To review the clinical, diagnostic and therapeutic features of this disease interesting for the urologist.

Methods/results: Case of a 47 year old male with history of cardiovascular disease who presents in the emergency room with left flank pain.

[High-flow priapism caused by bilateral arterio-lacunar fistula].

Objective: Literature review about arterial priapism cases secondary to bilateral postraumatic arterial-lacunar fistula, with special attention to therapeutic management by bilateral supraselective embolization.

Methods: Bibliographic search using MEDLINE. A new case of high flow priapism secondary to bilateral postraumatic arterial-lacunar fistula is reported.
