Simple renal cyst communicating with the excretory tract is a rare complication frequently arising from obstructive uropathy. In most of the cases treatment continues to be conservative.
Permanent bladder catheterization for medical or social reasons increases the risk of complications, especially urinary infection. We evaluated the usefulness of the balloon catheter with a steerable intravesical tip in reducing the volume of residual urine between the bladder neck and the balloon of the conventional Foley catheter. The results show that this new catheter affords no additional advantage over the conventional catheter.

We report on a renal transplant patient who had developed Kaposi's sarcoma with cutaneous involvement 20 days after transplantation. The patient had a functioning renal graft and was on immunosuppressive therapy consisting of prednisone, azathioprine and cyclosporine. Azathioprine and cyclosporine were discontinued and chemotherapy was instituted with vinblastine first and methotrexate later; however, Kaposi's tumor did not respond to the foregoing therapeutic regimen. Thirty-two months following transplantation, the kidney graft presented acute interstitial rejection that warranted graft removal. The patient is currently receiving treatment for Kaposi's sarcoma but tumor regression has not been achieved. We discuss the atypical course of this case in comparison with those reported elsewhere.
Two cases of renal trauma are described herein. The diagnostic work up revealed the patients had solitary kidney. Trauma was classified as grade 1 and 2 and a conservative approach was adopted. The patient with grade 2 trauma was submitted to surgery one month following treatment. Preservation of the renal unit was achieved in both patients. Patient follow up at 16 years revealed no complications or sequelae from the injury. The diagnostic and therapeutic aspects of renal trauma in patients with solitary kidney are discussed.
The present study evaluates extravesical ureteroneocystostomy, the technique used for reconstruction of the urinary tract in 120 kidney transplants. The urological complications ascribable to this technique were observed in 10% (12/120) and consisted of urinary extravasation (10), and ureteric obstruction (2). The treatment of the foregoing complications, which was successful in 8 cases, is described. The indications and advantages afforded by this technique in renal transplantation are discussed.
A case of obstructive uropathy secondary to a periurethral teflon injection, performed to correct urinary incontinence, is presented. The obstruction of one ureter was caused by an inflammatory reaction followed by fibrosis, which could be explained by the presence of a local infection or of intolerance to the teflon paste. The use of prophylactic antibiotics and routine renal echography are mandatory after periureteral or periurethral injections of large quantity of teflon.
