A case of giant renal calculus with poorly functioning opposite kidney
نویسنده
چکیده
Giant renal calculus is rarely seen in urologic practice. A 69-year-old woman who had right giant renal calculus with poorly functioning opposite kidney is presented. She was with a history of right pyelolithotomy for large renal calculus 10 years back. Ultrasonography(USG), uncontrast computed tomography ( CT ), plain abdominal X-ray ( KUB ) and intraveneous urography ( IVU ) revealed a giant renal calculus (10 x 8 cm) and grade III hydronephrosis on the right kidney and moderate calixiel dilation on the left kidney. Diethylene triamine pentaacetic acid ( DTPA ) renal scan showed good functioning affected kidney and poor functioning opposite kidney. Right pyelolithotomy was performed. During the manuplation of the stone removal, the stone was divided into five pieces spontaneously. This situation made the procedure easier. The stones were extracted without any complications, and a double-j ( DJ ) stent was placed to the patient. Chemical analysis of the stone revealed a calcium phosphate stone. KUB and IVU showed complete stone clearence and modarate dilatation on the right renal pelvis on the second month postoperatively. Like this case, today, open stone surgery is still continues to represent a reasonable alternative treatment option for some special cases.

BACKGROUND Neglected renal stones remain a major cause of morbidity in developing countries. They not only result in functional impairment of affected kidney, but also act as an important predisposing factor for development of urothelial neoplasms. It is not uncommon to miss an associated urothelial tumor in a patient of nephrolithiasis preoperatively. CASE PRESENTATION In last 3 years, we ca...

Primary hyperoxaluria (PH) disorder causes end-stage renal disease (ESRD). Missed diagnosis or relapse in transplanted kidney is common. We present a 36-year-old patient with a history of recurrent renal calculus which progressed to end-stage renal disease. He underwent kidney-transplant surgery.

Nuclear medicine imaging is routinely used for evaluation of perfusion and function of the transplanted kidneys. At present, the radiopharmaceutical of choice for this study in our center is Tc 99m-Ec. Complications of the kidney graft are demonstrable in the early and delayed images. One of these complications is vesicoureteral reflux to the graft or to the native kidneys. We present a 27 year...

AbstractRenal medullary carcinoma (RMC) is an uncommon aggressive neoplasm of the kidney. RMC is biologically aggressive with a very poor prognosis, and metastasis is seen in up to 95% of the patients at diagnosis or shortly thereafter. The common sites of metastasis are respectively lymph nodes, lungs, livers, and adrenal glands in order of frequency. The presence of poorly differentiated eosi...
