Primary malignant fibrous histiocytoma of the renal pelvis is extremely rare. This article reports a pathologically confirmed case. Surgery is the main treatment for this disease. Chemotherapy and radiotherapy have been reported to be ineffective. It is difficult to differentiate it from urothelial tumor of the renal pelvis and renal cell carcinoma by preoperative laboratory and radiological ev...

Primary squamous cell carcinoma (SCC) of renal pelvis is a rare neoplasm. A 75-year old male presented with history of chronic dull aching pain in left flank region for last 10-years with history of left pyelolithotomy about 30-years back. After proper workup, large calculus with heterogeneous density mass detected in nonfunctioning left kidney. After radical nephrectomy, histopathological exam...

Experiments were performed in vitro to explore the influence of isoproterenol on the canine pelvi-ureteral system. The rhythmic changes of intrapelvic pressure became no longer manifest and simultaneously recorded electromyograms revealed disappearance of peristalsis at sites distal to the upper region of renal pelvis following application of isoproterenol, while the pacemaker at the pelvi-caly...

OBJECTIVE This study describes the frequency of sonographically detected fetal renal disorders, the correlation of fetal renal pelvis dilatation (RPD) with the need for postnatal surgery, and proposed management of RPD. METHODS The study population consisted of 342 fetuses with prospectively identified isolated renal abnormalities and known follow-up. Fetuses with RPD were considered separate...

Background: Double ureter is one of the anomaly of urethra that appears complete or incomplete. Incomplete duplication of ureter is known as bifid ureter, this kind of anomaly may be formed due to some error or disturbance in development of the ureteric bud which arises from the mesonephric duct around the 5th week. The ureteric bud grows and penetrates in to the metanephric tissue at about32co...

Our presentation illustrates a rare case of primary renal pelvis malignant melanoma in a 35-year-old man. The diagnosis of malignant melanoma was based on immunophenotype and the detection of intracellular melanin pigment. The renal origin was proven by the presence of scattered melanocytes within the urothelium of the pelvis. The tumor exhibited extensive clear cell change that closely mimics ...

OBJECTIVE To analyze the prenatal outcomes in a cohort of fetuses with mild bilateral pyelectasis and determine whether performing serial ultrasounds is a good follow-up strategy. METHODS A prospective longitudinal study was conducted on 62 fetuses with mild bilateral pyelectasis. Fetal mild bilateral pyelectasis was considered when the renal pelvis measured (in millimeters) ≥5.0 to 10.0, ≥7....
