age of the patients was 36.4 (26-58) years. Four men (20%) had orchidectomy because the tumours were found to be malignant; the resected specimens yielded multifocal testicular intraepithelial neoplasia (TIN) in all patients and additional seminomatous tumour cells elsewhere in the testis in one. Frozen-section results were false-negative in one patient and he had orchidectomy after having established the definitive histological diagnosis. The 16 patients with benign lesions were correctly diagnosed and their testicles were not removed. CONCLUSIONSAdvanced and innovative ultrasonography technology allows the detection of increasingly small testicular masses. In the present series, most incidental intratesticular lesions were benign. In patients with malignant lesions, multifocal TIN and/or distant seminomatous foci were present despite the tumour being small. Therefore, it is essential to perform exploratory surgery as it is the only way to obtain accurate histological findings, thus providing oncological efficacy and precluding removal of a testicle bearing a benign lesion.

The L-RPLND has proved to be an excellent staging tool, which should be developed into a less-invasive alternative to primary open RPLND. The oncologic outcome of L-RPLND without adjuvant chemotherapy in pathologic stage II disease is being investigated.

Recurrent or multifocal TCC may represent a risk factor for secondary TCC of the remnant urothelium after cystectomy. In our series all recurrent tumors were late recurrences (more than 36 months postoperatively). Because the rate of urethral recurrence in the current series corresponds to that reported in men (2% to 6%), urethra sparing cystectomy with orthotopic bladder replacement does not appear to compromise the oncological outcome in women.

We report the first case of a diagnosis of an asymptomatic primary renal angiosarcoma. The patient underwent laparoscopic nephrectomy and is alive after long-term follow up. We provide the preoperative imaging studies and the histologic features of this exceedingly rare tumor.

These data show that the reported estimates of over diagnosis in the low total prostate specific antigen group are exaggerated in a screening population. Using our criteria prostate cancer under diagnosis occurs more frequently than over diagnosis in the total prostate specific antigen range of 4.0 to 10 ng/ml.

RESULTSPathological staging of specimens showed extracapsular extension in 69 patients, of whom 53 had pathological capsular perforation and 16 had seminal vesicle invasion. 3D-TRUS identified 58 patients with sites of extracapsular extension with 84% sensitivity, 96% specificity, 94% positive predictive value, 91% negative predictive value and an overall accuracy of 92%. Of the 16 patients with seminal vesicle invasion 14 were identified correctly on 3D-TRUS. Overall the 3D-TRUS staging sensitivity was 84%, specificity 96%, positive predictive value 93%, negative predictive value 91% and accuracy 91%. CONCLUSIONS3D-TRUS seems to be an accurate technique for staging localized prostate cancer. If 3D-TRUS indicates locally advanced disease, the probability of capsular perforation or seminal vesicle invasion is very high.
