A 26-year-old female, presented with discomfort and a lump in the left side of abdomen. Examination showed a non-tender cystic mass in the left lumbar region extending down to the pelvis, the lower limit being palpable through the left fornix. Investigations revealed a cystic mass extending from the left renal area to the pelvis and a nonvisualized left kidney. Cystoscopy could not identify the...

Methods enabling kidney-specific gene transfer in adult mice are needed to develop new therapies for kidney disease. We attempted kidney-specific gene transfer following hydrodynamic tail vein injection using the kidney-specific podocin and gamma-glutamyl transferase promoters, but found expression primarily in the liver. In order to achieve kidney-specific transgene expression, we tested direc...

Renal cell carcinoma (RCC) is the most common malignancy of the kidney. It is not commonly form tumor thrombus in the ureter or renal pelvis. A 29-year-old woman presented with asymptomatic gross hematuria. Contrast CT study revealed a tumor suspected to be a Transitional Cell Carcinoma (TCC). However, tumor thrombus was found in the renal pelvis and ureter. We performed Nephroureterectomy, bla...

BACKGROUND Carcinosarcoma is a malignancy that rarely occurs in the renal pelvis. MATERIALS AND METHODS We present a case of histologically proven, native renal pelvis carcinosarcoma in a 65-year-old woman who had accepted a renal transplant. We performed a laparoscopic ureterectomy, combined with lymph node dissection and immunosuppression with sirolimus (SRL), which was alternated with the ...

Renal cell carcinoma (RCC) originated from parenchyma and the majority of malignancies originating in the renal pelvis are transitional cell carcinoma (TCC). In the present study, a rare case of RCC growing into the renal pelvis and mimicking TCC in medical imaging is reported. The preoperative differentiation between RCC and TCC is important in order to identify the type of surgical treatment ...

Received July 2007 Accepted April 2008 INTRODUCTION Epithelial tumors originating from the renal pelvis are uncommon, and adenocarcinomas account for less than 1% of malignancies which arise from renal pelvic epithelium.(1) Primary mucinous epithelial tumors occurring in the kidney are presumed to originate from the multipotential renal pelvic epithelium. Most reported cases are malignant.(2) O...

Since August 1989, we have seen 4 patients with leukoplakia of the renal pelvis associated with a longstanding renal stone. In 2 of them, excretory or retrograde pyelography revealed multiple filling defects in the left renal pelvis as well as a renal stone, although urine cytological examination was negative. One of the other 2 patients underwent extracorporeal shock wave lithotripsy (ESWL) fo...

OBJECTIVES To evaluate the effectiveness of laparoscopic pyelolithotomy (LP) for staghorn stones (>3-4 cm) in patients with chronic liver disease or coronary artery disease. PATIENTS AND METHODS In all, 49 patients underwent LP; they were divided into four groups, with stones in group 1 in the renal pelvis only, in group 2 in the renal pelvis and one calyx, in group 3 in the renal pelvis and ...

The aim of the present study was to assess the morbidity of ampullary renal pelvis (ARP) and document its natural history in post-natal life. A total of 1,167 newborn infants with prenatally suspected hydronephrosis were retrospectively analyzed. Of these, 65 patients were diagnosed with ARP by computed tomography urography (CTU) and/or magnetic resonance urography (MRU). All cases were followe...
