Randomized Controlled Trial Comparative StudyComparison of lidocaine suppositories and periprostatic nerve block during transrectal prostate biopsy.
The aim of this randomized prospective and partially double-blind study was to evaluate the efficacy of transrectal lidocaine applied as suppositories in comparison to periprostatic infiltration as methods of reducing pain during transrectal prostate biopsy. 100 patients were randomized to four groups and received either a suppository containing 60 mg of lidocaine 2 h before biopsy, a 120-mg lidocaine suppository 1 h before biopsy, a 120-mg lidocaine suppository 2 h before biopsy, or they were anaesthetized with a periprostatic infiltration of 5 ml 2% lidocaine. In all patients the same 10-core transrectal biopsy technique was performed. Pain was evaluated using a visual pain scale ranging from 0 to 10 points. ⋯ No patient had severe pain. Eight of the 9 patients with no pain were in the periprostatic injection group. Thus, all lidocaine suppositories showed a good analgesic effect although a significantly better pain reduction was achieved by periprostatic lidocaine infiltration.

Case ReportsMalignant epithelioid renal angiomyolipoma involving the inferior vena cava in a patient with tuberous sclerosis.
Renal angiomyolipomas (AMLs) are mesenchymal tumors that occur either sporadically or are associated with tuberous sclerosis, and are generally considered to be benign. Malignant AML is extremely rare, and most are found to be epithelioid histopathologically. The authors report the case of a patient followed for renal AML. ⋯ The patient was treated by nephrectomy and tumor thrombectomy with retroperitoneal lymph node dissection. Histological examination demonstrated renal AML with a malignant epithelioid contingent. The various aspects of this histological and radiological variant are discussed.

Case ReportsTraumatic penile injuries--mechanisms and treatment.
Injuries of the penis are uncommon but represent urological emergencies. We report 3 cases of penile trauma illustrating the diversity of penile injury presentation. ⋯ An immediate operative exploration with removal of hematoma and primary defect closure should be done in every case. Surgical management should not be delayed to avoid late complications.
