Synchronous bilateral multilocular renal cell carcinoma - A rare case

A rare case of multilocular primary renal cell carcinoma (two sites in each kidney) in a 48-year-old woman is presented. The preoperative diagnosis was based on the computerized tomography findings. The patient underwent bilateral total nephrectomy and subsequently maintained renal dialysis. © 1994 Akadémiai Kiadó

A rare case of gigantic calyx dilatation manifested as renal ectopia

We present a very rare case of gigantic hydrocalycosis which was caused by an obstructed stone. It was so large that it displaced the rest kidney into the contralateral lumbar fossa giving the appearance of a crossed ectopic kidney. © 1995 Akadémiai Kiadó

Contribution of transcutaneous ultrasonography to the evaluation of urethral strictures

The aim of our study was to investigate the accuracy and sensitivity of ultrasound in detecting urethral strictures. Between 1992 and 1994, 117 patients with stricture of the anterior urethra were evaluated by retrograde urethrography, ultrasonography and urethroscopy

Tuberculosis of the prostate

We present five cases of tuberculous prostatitis. In all cases this was an incidental histologic finding after transurethral prostatectomy. The patients were all treated with an antituberculous drug regimen. A literature review of this rare condition is included

Stimulation of the obturator nerve during extracorporeal shock wave lithotripsy

This paper presents eight patients with lithiasis of the lower third of the ureter that were treated by extracorporeal shock wave lithotripsy (ESWL). All the procedures were performed with a Dornier HM4 lithotriptor in the sitting position. In all cases clinical signs of stimulation of the obturator nerve were presented. Because of the continuing movement of the patient and the possibility of damage to the obturator nerve, the lithotripsy was interrupted in the sitting position and was performed successfully with patients in the prone position. One possible explanation for the above phenomenon is that the increased abdominal pressure in the sitting position pushes the ureter with the stone towards the side walls of the pelvis and the obturator nerve. In this way, both obturator nerve and stone were included either in the zone of the high concentration of the shock waves, or in the secondary focal point, with the final result of stimulation of the nerve. By placing the patient into the prone position, the abdominal pressure is reduced, the ureter moves towards the center line, the obturator nerve gets away from the shock waves and the ESWL is completed freely without stimulation of the nerve. © 1995 Akadémiai Kiadó
