Evaluation of nefrotoxicity by tacrolimus and micophenolate mofetil associated with kidney ischemia and reperfusion: experimental study in rats.

Objective: to evaluate the renal toxicity caused by tacrolimus and mycophenolate mofetil (MMF) in a single kidney ischemia and reperfusion model.

Method: experimental study using Wistar rats, submitted to right nephrectomy and left renal ischemia for 20 minutes, separated into groups in the postoperative period (PO): 1) Control (nonoperated); 2) Sham (operated, without PO drug); 3) TAC0.1, TAC1 and TAC10, tacrolimus administered PO at doses of 0.

Inflammatory myofibroblastic bladder tumor: A very rare presentation.

Inflammatory myofibroblastic tumor (IMT) is a rare benign lesion with similarities to malignant lesions due to possible aggressive behavior. Although highly uncommon, this condition usually occurs in lungs and retroperitoneum. The involvement of the genitourinary tract represents a singular occasion.

Fever of unknown origin, a rare presentation of metastatic prostate cancer: Case report.

Metastatic prostate cancer can have an initial presentation with fever and systemic inflammatory response syndrome. Accurate diagnosis allows to differentiate this type of cancer from infectious conditions and to start early treatment. We report one case, in which the patient presented to the emergency department with lower urinary tract symptoms, fever and consumptive syndrome.

Prostate imaging reporting and data system correlation with Gleason score: Pathological aspects of magnetic resonance imaging findings.

Objective: Prostate cancer has a high prevalence and mortality, being the most diagnosed urologic cancer. Prostatic magnetic resonance imaging showed high sensitivity in the detection of clinically significant neoplasia and agreement with the Gleason score. Therefore, we attempted to evaluate the diagnostic accuracy of the prostate imaging reporting and data system, using biopsy and prostatectomy as the reference standard.

The use of double-J catheter decreases complications of retroperitoneoscopic ureterolithotomy.

Objective: To evaluate the retroperitoneoscopic ureterolithotomy in the treatment of ureteral calculi and the need for double-J catheter to reduce the procedure-related complications.

Methods: We conducted a retrospective study with 47 patients submitted to retroperitoneoscopic ureterolithotomy, of which 31 were selected and divided into two groups: Group 1, whose patients did not have double-J catheter placement, and Group 2, who underwent perioperative double-J catheter implantation. Data collected comprised pre-and post-operative excretory urography, operative time, postoperative analgesia, length of hospital stay and catheter removal.
